Description

The present invention relates to a prone position support device that supports various prone positions, such as upper limb flexion, lower limb flexion, upper limb extension, lower limb extension, and kneeling position, and a transport cart that carries and transports the device.

Children with severe motor disabilities need to lie prone several times a day in order to expel phlegm, and traditionally, urethane cushions with dimensions and shapes set to fit each child's body were used as positioning aids to support their bodies. In this case, it was necessary to remake the cushions as the child grew.

For example, the cushion shown in Patent Document 1 (JP Patent Publication 7-246134) is an example of such a posture-maintaining device. It has two wedges made of a foam material surrounded by an upholstery cloth, and a mat attached to each wedge, and when the mats are partially overlapping, the weight of the body causes the two wedges to be fixed apart from each other. The mat is in the form of a sheet, and is fixed to the wedge at a distance above the lower edge of the wedge. Support cushions for stabilizing supine, prone and lateral positions of adults and infants are known, which have an inclined and/or arc-shaped mat band to increase the fixing stress that contacts the body.

In addition, Patent Document 2 (Patent No. 5968246) describes a bedding set for prone position, comprising a pillow section, a mattress section, and a chest support device placed on the mattress section to support the chest of a user in prone position, the pillow section comprises a forehead section capable of supporting the forehead of the user when viewed in plan, a cheek section capable of supporting the cheeks, eye grooves capable of receiving both eyes, and a trapezoidal nasal groove capable of receiving the nose and mouth, the eye grooves and the nasal grooves being mutually connected to each other so as to form a single exhalation diffusion section that penetrates the pillow section in the thickness direction, and the nasal groove is configured to be positioned so that the chin of the user is supported by the pillow section. The pillow is open on the side, and a maxillary section capable of supporting the maxilla of the user is formed below the eyeball groove when viewed in plan, and the maxillary section forms a bulge that bulges toward the inside of the trapezoidal nasal-oral groove. The mattress section includes a chest mattress section and a lumbar mattress section that respectively correspond to the chest and lumbar regions of the user, the lumbar mattress section having a length of 200 mm to 300 mm, and the chest mattress section having a width smaller than that of the lumbar mattress section.

The prone position bedding set shown in Patent Document 3 (JP 2019-98102 A) includes a pillow with holes formed to face the user's eyes, nose, and mouth, an upper body support section for supporting the user's shoulders, chest, and abdomen, a waist support section for supporting the user's waist, and a footrest section for supporting the user's feet at a predetermined height. The upper body support section is composed of a shoulder support cushion area for supporting the user's shoulders, an abdominal support cushion area for supporting the user's abdomen, which is formed higher than the shoulder support cushion area, and a recess formed between the abdominal support cushion area and the shoulder support cushion area and located in the user's chest.

However, during the course of care, posture-maintaining devices need to be changed in a variety of ways, such as from prone position to upper limb flexion and lower limb flexion, upper limb extension and lower limb extension, kneeling position, etc. However, as described above, posture-maintaining devices made of cushions, whose dimensions are fixed at the manufacturing stage, require different cushion arrangements and combinations for each posture, making it difficult to fine-tune the posture. This places a heavy burden on caregivers to stably maintain or reproduce that posture, and the devices need to be remade each time as the child's body size changes as they grow.

In view of the above circumstances, the present invention aims to provide a prone position support device that can be easily modified to accommodate various prone positions, allows easy fine adjustment of the position, reduces the burden of care required to stably maintain or reproduce that position, and can instantly accommodate changes in body size as the child grows, as well as a transport cart capable of transporting the prone position support device with a prone human body mounted on it.

(Prone position support device)
The present invention relates to a prone position supporting device comprising a torso frame consisting of a pair of left and right side skeletons and a cross skeleton horizontally disposed between the pair of side skeletons, the torso frame having a length and width capable of holding the chest to abdomen of a human body in a prone position, an arm frame consisting of a pair of left and right side skeletons and a cross skeleton horizontally disposed between the pair of side skeletons, the length and width being capable of holding the arm of the human body, a thigh frame consisting of a pair of left and right side skeletons and a cross skeleton horizontally disposed between the pair of side skeletons, the length and width being capable of holding the thigh of the human body, and angle adjustment mechanisms provided between the side skeletons of the torso frame and the arm frame, and between the side skeletons of the torso frame and the thigh frame, respectively, and a cushioning device exteriorly mounted on the skeleton body, wherein each angle adjustment mechanism has a pair of connecting parts connected between the side skeletons, a horizontal support shaft passing through between the horizontally aligned tips of the pair of connecting parts, and each horizontal support shaft being provided with a quick release tightening mechanism. It may also be provided with a lower leg frame consisting of a pair of left and right side skeletons and a cross skeleton spanning between the pair of side skeletons, the length and width of which are set to be capable of holding the lower leg of a human body.

The present invention relates to a prone position support device in which a face frame with openings in areas corresponding to the eyes, nose, mouth, and neck is attached to the torso frame via an attachment/detachment mechanism, and the cushion device is provided with a neck pad corresponding to the neck portion of a prone human body and/or an abdominal pad corresponding to the abdominal portion, which are detachably attached to the torso frame.

The present invention relates to a prone position support device in which a knee frame consisting of a lateral skeleton with a length equivalent to the knee of a human body in a prone position is disposed between the thigh frame and the lower leg frame, and the angle adjustment mechanism is provided between the lateral skeletons of the thigh frame and the knee frame, and between the lateral skeletons of the knee frame and the lower leg frame.

The present invention relates to a prone position support device in which arms and legs are connected to the arm frame via a detachable mechanism, and the arm frame is equipped with arms and legs with casters that are interchangeable with the arms and legs via the detachable mechanism.

(Functions of each part of the prone position support device)
The following effects can be obtained with this skeletal body.
For example, it can be fitted with a cushioning device, and a face frame and/or a saddle frame, and holds the human body in a supine position. It can be transformed into a shape that corresponds to various prone positions according to the user's condition and wishes. It can secure space for a tracheotomy cannula, space for expectoration procedures, etc., in the part that corresponds to the neck of a user in a supine position, and also can secure space to avoid interference with tubes for gastrostomy or enterostomy, pouches for artificial anus, etc. It is temporarily fixed and mounted on a transport cart.

The torso frame provides the following effects. For example, its front end supports the base end of our arm frame, and its rear end supports the base end of our thigh frame, and serves as the target for mounting the cushioning device. It holds the chest and abdomen of a prone human body in various positions according to the user's condition and wishes. It detachably supports the face frame. In the case where a saddle frame is provided, it detachably supports the saddle frame. It detachably supports a neck pad at a position corresponding to the neck of a prone human body, and/or an abdominal pad at a position corresponding to the abdominal part.

The arm frame provides the following effects. For example, the base end of the arm frame is connected to the front end of our torso frame via an angle adjustment mechanism, and the posture of the arm frame can be changed according to the user's condition and wishes, and it holds the left and right arms of a prone body. The arm frame can be made up of only an upper arm frame. The upper arm frame supports the left and right upper arms of a prone body. It is a target for mounting a cushioning device. The arm frame is made up of, for example, an upper arm frame and a forearm frame connected thereto, and supports the base end of the forearm frame detachably relative to the tip of the upper arm frame.

When a forearm frame is provided, the forearm frame supports the left and right forearms of a prone human body. For example, the forearm frame is the subject to which a cushioning device is attached. When the forearm frame is connected to the tip of the upper arm frame via an angle adjustment mechanism, the support angle relative to the upper arm frame can be adjusted.

The arms and legs provide the following effects. For example, they support the front of the prone position support device. In a device equipped with a front height adjustment mechanism, the height of the front of the prone position support device can be adjusted and temporarily fixed at the adjusted height. In a device in which arms and legs are connected to the arm frame via a detachable mechanism, and arms and legs with casters that are interchangeable with the arms and legs are equipped to the arm frame via the detachable mechanism, when the arms and legs of the prone position support device are replaced with ones with casters, the caregiver can grasp the rear end of the prone position support device and lift it up with only the casters touching the ground, making it easy to move.

The thigh frame provides the following effects. For example, its base end is connected to the rear end of our torso frame via an angle adjustment mechanism, and its posture can be changed according to the user's condition and wishes, supporting the left and right thighs of the prone position human body. It is the subject of attachment of a cushioning device. In the case where the thigh legs are provided via an attachment/detachment mechanism, the thigh legs support the thigh frame of the prone position holding device. In the case where the thigh legs are provided with a mid-height adjustment mechanism, the height of the thigh frame of the prone position holding device can be adjusted and temporarily fixed at the adjusted height.

The knee frame provides the following effects. For example, when the knee frame is provided between the thigh frame and the lower leg frame via an angle adjustment mechanism, the frame portions corresponding to the left and right knees of the prone human body are no longer bent at an acute angle into a V shape when viewed from the side, but are bent into an L or U shape, reducing the stress on the left and right knees of the user. The knee frame supports the lower legs of the prone human body in various positions depending on the condition and wishes of the user. It is a target for mounting a cushioning device.

The lower leg frame provides the following effects. For example, its base end is supported by the rear end of the torso frame via the thigh frame (knee frame) and various angle adjustment mechanisms, and supports the lower leg of a prone human body in various postures according to the user's condition and wishes. It is the target for mounting the cushion device. In the case where the lower leg is provided, the lower leg touches the ground together with the arm leg and thigh leg to support the lower leg frame. In the case where the lower leg is provided with a rear height adjustment mechanism and/or an angle adjustment mechanism, even if the posture or height of the lower leg frame is changed due to the influence of the height of the arm leg and thigh leg, the lower leg is adjusted to touch the ground and/or rotated, and can be temporarily fixed in that grounded posture.

The pair of left and right side skeletons of each of the frames provide the following functions. For example, they support both the left and right ends of each cross skeleton, maintain the ladder shape of each frame, and ensure the strength of the frame. They support the angle adjustment mechanism, making it possible to maintain the posture of the skeleton body in a set state. Together with each cross skeleton, they support both ends of the support belt that holds the lower side of a prone human body. They are targets for the installation of belt loops.

The length adjustment mechanism provides the following effects. For example, the length of each side frame of each frame can be adjusted, temporarily fixed at the adjusted length, and set to a length dimension that matches the length of each part of the user's body.

The cross skeletons provide the following effects. For example, the left and right ends of each cross skeleton support the left and right side skeletons, ensuring the strength of each frame. They can be connected to an angle adjustment mechanism. They can serve as handles for moving the prone position support device or changing its posture. They can be grounded to the mounting mechanism of a transport cart and temporarily fixed thereto.

For example, if the pair of left and right side skeletons of the torso frame have a concave shape or a concave bend at a location corresponding to at least one of the left and right sides of the neck and/or abdomen of the prone human body, it becomes possible to avoid interference with or lead out a cannula for tracheotomy, a tube for gastrostomy or enterostomy, a pouch for an artificial anus, etc. Furthermore, if the cross skeleton of the torso frame is bent so that the midway part between the left and right ends corresponding to at least one of the neck and/or abdomen of the prone human body bulges out towards the back side of the torso frame, it becomes possible to avoid interference with medical cannulas, tubes, pouches, other medical devices, wearable devices, etc., or lead out towards the back side of the torso frame.

The face frame provides the following effects. For example, it holds the head of a prone human body in an appropriate front-to-back position. With a flat head pad exterior, it is possible to support the sides of the head of a prone human body. With openings in the areas corresponding to the eyes, nose, mouth, and neck, it is possible to hold the face facing straight down, and with a forehead pad and left and right cheek pads, the frontal bone and left and right cheekbones are stably held by the pads, reducing stress, and eliminating any obstructions to the neck, making it easier to place a cannula via tracheotomy and perform procedures such as expectoration.

The cushioning device provides the following effects. For example, it stably supports a prone body, disperses pressure, and reduces stress. The detachable neck pad holds the neck of a prone body, and can be removed to provide space for a tracheotomy cannula or to perform a phlegm removal procedure. The detachable abdominal pad holds the abdomen of a prone body, and can be removed to provide space for a gastrostomy or enterostomy tube, an artificial anus pouch, or the like. The abdominal pad removed from the torso frame can be moved onto the lower leg frame or arm frame (forearm frame) and used as an ankle or wrist pad.

Furthermore, for example, if the cushioning device has forearm pads, it exerts cushioning properties over a wide range of forearm movement, dispersing pressure. If it has shoulder pads, it holds both shoulders of the prone body. If it has trunk pads, it holds the chest of the prone body from the left and right outside, preventing abduction. If it has pelvic pads, it holds the lumbar region of the prone body from the left and right outside, preventing abduction. If it has adduction prevention pads, it prevents the lower limbs of the prone body from crossing or falling over. If it has abduction prevention pads, it holds the lower limbs of the prone body from the left and right outside, preventing abduction. If it has a chest belt and/or pelvic belt, it restrains the chest and/or abdomen or buttocks of the prone body against the torso frame, preventing movement or falling off.

(Transport cart)
The present invention relates to a transport cart for the prone position support device, which comprises a chassis having wheels and a mounting mechanism that is provided on the chassis and temporarily fixes the skeletal body.

The present invention relates to a transport cart for the prone position support device, which comprises a chassis having wheels, at least left and right parallel rails provided on the chassis, at least two sliders, one in front and one in back, that are horizontally mounted between the left and right parallel rails and equipped with a braking mechanism that can move forward and backward and can be temporarily fixed, and a mounting mechanism provided on each slider for temporarily fixing the skeleton body to each slider.

(Functions of each part of the transport cart)
The chassis provides the following effects. For example, it supports a mount mechanism supported on wheels so that it can be moved freely. The mount mechanism supports the prone position support device mounted on the chassis so that it can be detached and temporarily fixed. The parallel rails support each slider so that it can slide in the front-rear direction relative to the chassis. Each slider allows the respective mount mechanism to move forward and backward along the parallel rails. Each angle adjustment mechanism is adjusted during the posture setting process, and each ground contact point of the prone position support device that has been moved forward and backward can be placed on each mount mechanism so that it can be detached and temporarily fixed. The brake mechanism temporarily fixes each slider on which the prone position support device is mounted so that it does not move forward and backward relative to the parallel rails.

The present invention has the excellent effect of providing a prone position support device that can be easily modified to accommodate various prone position positions, allows easy fine adjustment of the position, reduces the burden of care required to stably maintain or reproduce that position, and can immediately respond to changes in body size as the child grows, as well as a transport cart that can transport the prone position support device carrying a prone human body.

(Prone position support device)
A prone position support device according to a first embodiment of the present invention will be specifically described below with reference to Fig. 1 to Fig. 9. In particular, this embodiment includes, for example, a torso frame 3, which is made up of a pair of left and right side skeletons SF having a length adjustment mechanism 30 and a cross skeleton CF horizontally disposed between the pair of side skeletons SF, and is set to a length and width capable of supporting the chest to abdomen of a prone position human body; an arm frame 4, which is made up of a pair of left and right side skeletons SF having a length adjustment mechanism 41 and a cross skeleton CF horizontally disposed between the pair of side skeletons SF, and is set to a length and width capable of supporting the arms of the human body; a thigh frame 5, which is made up of a pair of left and right side skeletons SF having a length adjustment mechanism 50 and a cross skeleton CF horizontally disposed between the pair of side skeletons SF, and is set to a length and width capable of supporting the thighs of the human body; and a pair of left and right side skeletons SF having a length adjustment mechanism 70. The prone position maintaining device 1 may be provided with a skeletal body 2 having a lower leg frame 7 which is made up of a pair of side skeletons SF and a cross skeleton CF which is horizontally disposed between the pair of side skeletons SF and which is set to a length and width capable of holding the lower leg of a human body, and angle adjustment mechanisms 8 which are provided between the lateral skeletons SF of the torso frame 3 and the arm frame 4 and between the lateral skeletons SF of the torso frame 3 and the thigh frame 5, respectively, and a cushioning device 9 which is exteriorly mounted on the skeletal body 2, and each angle adjustment mechanism 8 has a pair of connecting parts 80, 81 connected between the lateral skeletons SF, a horizontal support shaft 82 which passes through between the horizontally aligned tips of the pair of connecting parts 80, 81, and each horizontal support shaft 82 is provided with a quick release tightening mechanism 82.

The pair of left and right side frameworks SF of the body frame 3 each have a length adjustment mechanism 30, for example, a pair of long and short square pipes SF1, SF2, with multiple positioning holes h1 drilled at equal intervals along the longitudinal direction in the side wall of the long square pipe SF1. The base end of an adjustment shaft SF3, which is inserted into the long square pipe SF1 so as to be able to move back and forth, is concentrically connected to the short square pipe SF2. A positioning hole h2 is drilled in the side wall of the adjustment shaft SF3.

The adjustment shaft SF3 of the short square pipe SF2 is advanced or retreated relative to the long square pipe SF1 to adjust the overall length of the side frame SF, and a temporary fixing shaft TS (FIG. 7) is attached to the adjustment shaft SF3 and the arbitrarily selected and aligned positioning holes h1, h2 of the long square pipe SF1, so that the short square pipe SF2 is temporarily fixed to the long square pipe SF1.
The temporary fixed shaft TS may be, for example, a bolt and nut, or a shaft having a head with an annular groove carved into the outer periphery of the tip thereof into which an E-ring is fitted, and may consist of a bolt and nut with an integrated handle knob as shown in FIG. 7(a).

For example, the pair of left and right side frames SF of the body frame 3 are integrated by horizontally connecting one or more cross frames CF in a ladder shape. Each cross frame CF can be made of, for example, a round pipe, an elliptical pipe, a square pipe, or a polygonal pipe.

Each side skeleton SF and each cross skeleton CF of the torso frame 3 may be bent in a concave shape (bulging toward the back side of the torso frame 3) toward the bottom of the torso frame 3 at a position to avoid contact with or pressure on a cannula for tracheotomy, a catheter (tube) for gastrostomy or enterostomy, a stoma pouch, etc., of a prone human body, or to secure a route for tubes and wiring of various wearable devices. For example, as shown in Figures 5(a) and 8(c) and (d), the cross skeleton CF arranged at a position to secure a route for a catheter (tube) for gastrostomy or enterostomy may have a midway portion between both ends connected to a pair of left and right side skeletons SF that is 5 to 30 cm away from a plane formed by a pair of left and right side skeletons SF, forming a concave curve, V-shape, U-shape, or concave shape toward the back side. As shown in Figures 2 and 5(a), for example, the middle part of each of the cross skeletons CF of the torso frame 3, upper arm frame 40, and thigh frame 5 is bent in a bulging manner toward the back surface of each frame 3, 40, 5, and the bulging middle part of each cross skeleton CF becomes the gripping part of each frame 3, 40, 5. Furthermore, the middle part or end of each side skeleton SF of the torso frame 3 can be bent in a concave manner (not shown) to ensure a route for medical tubes and wiring of equipment.

The torso frame 3 is set to a length and width that can hold the chest to abdomen of a prone human body. For example, a child's small size can have a width between the left and right ends of 400 mm to 700 mm, preferably 550 mm, and a length of 260 to 350 mm when the length adjustment mechanism 30 is adjusted to the shortest position, and 280 to 530 mm when adjusted to the longest position, preferably 279 mm when adjusted to the shortest position, and 426 mm when adjusted to the longest position.

The arm frame 4 may have, for example, an upper arm frame 40 and a forearm frame FA. The pair of left and right side skeletons SF of the upper arm frame 40 is formed by one or more cross skeletons CF similar to those described above being horizontally connected in a ladder shape and integrated with each other. Each side skeleton SF is set to a length and width capable of holding the upper arm of a prone human body. For example, a child's S size is made of a square pipe SF with a length of 330 mm and is set to the same left-right width as the torso frame 3. For example, a plurality of positioning holes h1 are drilled in the side walls of the left and right square pipes SF of the upper arm frame 40 at equal intervals along the longitudinal direction. Each positioning hole h1 forms part of a length adjustment mechanism 41 described later.

The base end of the upper arm frame 40 is connected to the front end of the torso frame 3 via an angle adjustment mechanism 8. For example, the base ends of the pair of left and right side skeletons SF of the upper arm frame 40 and the left and right ends of the cross skeleton CF are connected via an angle adjustment mechanism 8, and the front ends of the pair of left and right side skeletons SF of the torso frame 3 and the left and right ends of the cross skeleton CF are connected via an angle adjustment mechanism 8, or the middle part of the cross skeleton CF located at the base end of the upper arm frame 40 is connected to the middle part of the cross skeleton CF located at the front end of the torso frame 3.

For example, an angle adjustment mechanism 8 is provided between the base end of the pair of left and right side skeletons SF of the upper arm frame 40 and the front end of the pair of left and right side skeletons SF of the torso frame 3, and they are connected to each other so that the angle can be freely adjusted. The angle adjustment mechanism 8 has, for example, a connecting part 80 whose base end is fitted into and connected to the front end of the side skeleton SF of the torso frame 3, and a connecting part 81 whose base end is fitted into and connected to the base end of the side skeleton SF of the upper arm frame 40, and horizontal shaft holes penetrating in the horizontal direction are drilled in the tips of the pair of connecting parts 80, 81, which are aligned horizontally, and unevenness that mesh with each other at unit angles is engraved around the horizontal shaft holes in the joint walls of the tips. A horizontal support shaft 82 having a quick release lever 82 as a quick release tightening mechanism 82 is inserted through the horizontal hole, and when the quick release lever 82 is released, the projections and recesses are released from engagement, making the angle adjustable, and when the quick release lever 82 is closed, the projections and recesses are engaged, temporarily fixing the angle so that it cannot be adjusted.

The forearm frame FA is formed by connecting one or more cross skeletons CF horizontally in a ladder shape between a pair of left and right side skeletons SF, which are integrated with each other. Each side skeleton SF is set to a length and width that can hold the forearm of a prone human body. For example, a child's S size is made of a square pipe SF with a length of 200 mm, and is set to the same left and right width as the torso frame 3. A pair of left and right advance/retract shafts FA1, which form the other part of the length adjustment mechanism 41, are connected to the base ends of the pair of left and right side skeletons SF via the angle adjustment mechanism 8 similar to that described above, so that the angle can be freely adjusted and the shafts can be temporarily fixed. The pair of left and right advance/retract shafts FA1 are provided with positioning holes h2 corresponding to the positioning holes h1. The length adjustment mechanism 41 has a structure similar to that of the length adjustment mechanism 30 described above, and each of the advance/retract axes FA1 can be advanced and retreated relative to the upper arm frame 40, and the length can be adjusted to match the upper arm of a prone human body, and the temporary fixing axis TS can be attached to the aligned positioning holes h1, h2, and temporarily fixed.

For example, the arm legs 42 are attached to the outer wall on the back side of the upper arm frame 40 in a removable and/or height-adjustable manner via a front height adjustment mechanism 43 that also serves as an attachment/detachment mechanism. The arm legs 42 may have, for example, a ground pipe RP1 bent into a U-shape with a length of 200 mm and a width of 550 mm, with a cross frame laid horizontally in a ladder shape, and a base pipe RP2 with a pair of left and right round pipes RP2 with a length of 393 mm connected midway between the left and right parts in an H shape by a cross frame, and both base ends of the ground pipe RP1 and the tips of both base pipes RP2 are connected via an angle adjustment mechanism 8 with a structure similar to that described above so that the angle can be adjusted and the angle can be temporarily fixed.

The front height adjustment mechanism 43 has a casing 43a connected in parallel to the outer wall of the back side of the left and right side skeletons SF of the upper arm frame 40. The base pipe RP2 is inserted into each casing 43a so that it can slide and move forward and backward (height adjustable). Each casing 43a is provided with a temporary fixing mechanism 43b that temporarily fixes the forward and backward movement of each base pipe RP2. As shown in FIG. 7(a), the tip of the casing 43a is provided with a quick release lever 43c as a quick release tightening mechanism that wraps around the outer periphery of the base pipe RP2 to reduce its diameter and tighten it, and can prevent rattling at the tip of the casing 43a at a corresponding point in the middle of the base pipe RP2.

As shown in FIG. 2 and FIGS. 8(a) and (b), the arm/leg 42 may be interchangeable with an arm/leg 44 that has casters.
The caster-equipped arm leg 44 may be, for example, a pair of left and right round pipes 44a with a length of 200 mm, each end of which has a caster 44b, a cross frame CF that is spanned between the ends of the left and right round pipes 44a, a ground side pipe 44a that is roughly U-shaped with a width of 550 mm, and a base end pipe RP2 that has the same structure as described above, and both base ends of the ground side pipe 44a and the tips of both base end pipes RP2 are connected via an angle adjustment mechanism 8 that has the same structure as described above so that the angle can be adjusted and the angle can be temporarily fixed. The caster-equipped arm leg 44 is inserted into the casing 43a via the front height adjustment mechanism 43, for example, so that it can slide and move forward and backward (height can be adjusted).

The caster-equipped arms and legs 44 are, for example, temporarily fixed by the temporary fixing mechanism 43b so that each base pipe RP2 cannot slide against the casing 43a. In addition, for example, a quick release lever 43c as a quick release tightening mechanism that can be wrapped around the base pipe RP2 and the casing 43a and tightened can prevent the base pipe RP2 from wobbling at a corresponding location midway against the tip of the casing 43a. As shown in Figure 8 (b), the prone position support device 1 equipped with the caster-equipped arms and legs 44 can be pushed and pulled by grasping the rear ends (such as cross bones) of the lower leg frame 7 and the lower leg 71, etc., and lifting them so that only the casters 44b are in contact with the ground.

As shown in FIG. 5(a), the arm legs 42 can be connected to the left and right outer walls of the arm frame 4 via a front height adjustment mechanism 43 that also functions as an attachment/detachment mechanism, and can be dimensioned to have a wider left-right end width than the torso frame 3 and arm frame 4. For example, the thigh legs 51 and crus legs 71 described below can also be similarly connected to the left and right outer sides, and can be dimensioned to have a wider left-right end width than the torso frame 3 and arm frame 4.

The thigh frame 5 is set to a length and width that can hold the thigh of a prone human body. The pair of left and right side skeletons SF of the thigh frame 5 is formed by horizontally connecting one or more cross skeletons CF in a ladder shape to be integrated with each other. The thigh frame 5, for example, of a child's S size, has the same width between the left and right ends as the torso frame 3, and the length is set to 260 to 350 mm when the length adjustment mechanism 50 is adjusted to the shortest length, and 280 to 530 mm when adjusted to the longest length, preferably 279 mm when adjusted to the shortest length, and 426 mm when adjusted to the longest length. The length adjustment mechanism 50 can have a structure similar to that of the length adjustment mechanisms 30 and 41 described above. For example, an angle adjustment mechanism 8 having a structure similar to that described above can be provided between the rear end of the torso frame 3 and the tip of the thigh frame 5, and they can be connected to each other so that the angle adjustment and the angle posture can be temporarily fixed.

The angle adjustment mechanism 8 can be provided, for example, between the rear ends of the pair of left and right side skeletons SF of the torso frame 3 and the front ends of the pair of left and right side skeletons SF of the thigh frame 5. Also, it can be provided between the middle part between the left and right ends of the cross skeleton CF that is horizontally laid between the rear ends of the pair of left and right side skeletons SF of the torso frame 3 and the middle part between the left and right ends of the cross skeleton CF that is horizontally laid between the front ends of the pair of left and right side skeletons SF of the thigh frame 5. Furthermore, it can be connected so as to span between the rear ends of the pair of left and right side skeletons SF of the torso frame 3 and the left and right ends of the cross skeleton CF that is horizontally laid between them, and between the front ends of the pair of left and right side skeletons SF of the thigh frame 5 and the left and right ends of the cross skeleton CF that is horizontally laid between them.

For example, the thigh legs 51 are attached to the outer wall on the back side of the thigh frame 5 in a removable and/or height adjustable manner via a height adjustment mechanism 52 that also serves as an attachment/detachment mechanism. The thigh legs 51 are bent into a U-shape, for example, 200 mm long and 550 mm wide, and have a ground pipe RP3 with a cross skeleton CF suspended horizontally in a ladder shape.

The height adjustment mechanism 52 is, for example, a case 52a connected in parallel to the outer wall of the back side of the side frame SF of the thigh frame 5, and the left and right parallel pipe parts of the ground pipe RP3 are inserted so that they can slide and move back and forth (height adjustable). A temporary fixing mechanism 52b that fixes the forward and backward movement of the left and right parallel pipe parts of the ground pipe RP3 is provided on the case 52a, and the left and right parallel pipe parts of the thigh leg 51 can be temporarily fixed to the case 52a so that they cannot slide. Furthermore, as shown in Figures 2 and 7(a), a quick release lever 52c is provided at the tip of the case 52a as a quick release tightening mechanism that wraps around the outer periphery of the left and right parallel pipe parts of the thigh leg 51 and can be tightened by reducing the diameter, and the tip of the case 52a can be made to prevent rattling of the mid-point of the left and right parallel pipe parts of the thigh leg 51.

The lower leg frame 7 is set to a length and width capable of holding the lower leg including the foot of a prone human body. The pair of left and right side skeletons SF of the lower leg frame 7 is formed by horizontally connecting one or more cross skeletons CF in a ladder shape and integrating them with each other. The lower leg frame 7, for example, of a child's S size, has the same width between the left and right ends as the torso frame 3, and the length is set to 400 to 440 mm when the length adjustment mechanism 70 is adjusted to the shortest length, 440 to 480 mm when adjusted to the longest length, preferably 420 mm when adjusted to the shortest length, and 445 mm when adjusted to the longest length. The length adjustment mechanism 70 can have a structure similar to that of the length adjustment mechanisms 30, 41, and 50 described above. For example, between the tip of the lower leg frame 7 and the rear end of the thigh frame 5, two angle adjustment mechanisms 8 (four in total, one on each side) with the same structure as described above, and one knee frame 6 on each side, are interposed between the angle adjustment mechanisms 8, and they can be connected to each other so that the angles can be adjusted and the angle postures can be temporarily fixed.

The lower leg frame 7 may be provided with the angle adjustment mechanism 8 between the tips of the pair of left and right side skeletons SF and the rear ends of the pair of left and right side skeletons SF of the thigh frame 5. The middle part between the left and right ends of the cross skeleton CF horizontally laid between the rear ends of the thigh frame 5 and the middle part between the left and right ends of the cross skeleton CF horizontally laid between the front ends of the lower leg frame 7 may be connected via the angle adjustment mechanism 8. Furthermore, one connecting part 80 of the angle adjustment mechanism 8 may be connected between the rear ends of the pair of left and right side skeletons SF of the thigh frame 5 and the left and right ends of the cross skeleton CF horizontally laid between them, and the other connecting part 80 of the angle adjustment mechanism 8 may be connected between the front end of the lower leg frame 7 and the left and right ends of the cross skeleton CF horizontally laid between them, such that the angle adjustment mechanism 8 allows the mutual angle adjustment and temporary fixation of the angle posture.

For example, the lower leg frame 7 may have a foot frame (not shown) added to its rear end, the length and width of which are set to be able to hold the foot of a prone human body. The foot frame may be, for example, a pair of left and right side skeletons formed in a U-shape by a cross skeleton that is placed horizontally between at least the rear ends of the side skeletons, the width between the left and right ends of which is the same as that of the lower leg frame 7, the length of which is 50 mm to 150 mm, two angle adjustment mechanisms 8 having the same structure as described above are arranged between the rear end of the lower leg frame 7 and the front end of the foot frame, and the foot frame may be connected to the lower leg frame 7 so that the angle can be adjusted and the angle position can be temporarily fixed.

Also, for example, as shown in FIG. 7(a), an ankle pad AN can be provided on the lower leg frame 7 instead of the foot frame. The ankle pad AN can be a pad with a side cross-sectional shape, such as a triangular, arc-shaped, or semicircular cross-sectional shape, that can support the raised ankle and shin when the knee or instep of a prone human body is placed on the upper surface of the lower leg frame 7. For example, the ankle pad AN can be provided with a means for attaching and detaching to the cushion sheet LBC, such as a hook-and-loop fastener or a hook.

The knee frame 6 is set to a length and width that can hold the knees of a prone human body. The knee frame 6 can be, for example, made up of a pair of left and right side skeletons SF, or one or more cross skeletons CF can be horizontally connected to the pair of left and right side skeletons SF in a ladder shape and integrated with each other. The knee frame 6 can be, for example, a small size for children, with the width between the left and right ends set to the same as the torso frame 3 and the lower leg frame 7, and the length set to 50 mm to 250 mm. Each angle adjustment mechanism 8 can be connected to the front and rear ends of the pair of left and right side skeletons SF of the knee frame 6. In addition, when the knee frame 6 is provided with a cross skeleton CF, each angle adjustment mechanism 8 can be connected to either the middle part between the left and right ends of the cross skeleton CF of the knee frame 6, or between the left and right joint ends of the pair of left and right side skeletons SF and the cross skeleton CF.

In the case where the knee frame 6 is not provided between the thigh frame 5 and the lower leg frame 7, for example, a knee holding mechanism is provided in which a number of cross-piece plates, whose width corresponds to the width between the left and right ends of the thigh frame 5 (lower leg frame 7), have angle-restricting engagement parts that limit the bending angle between them to an obtuse angle along the length of the length of the angle adjustment mechanism 8 that connects the thigh frame 5 and the lower leg frame 7, and are connected so that they can be arranged in a multi-jointed curved shape around a horizontal axis, preventing the knee of a prone human body from being held between the frames at an acute V-shape when viewed from the side, and holding it at a gentle U- or L-shape angle, thereby reducing stress on the knee.

As shown in FIG. 2, the lower leg frame 7 is provided with left and right short hanging pipes 72 at a position slightly toward the rear end of the pair of left and right side skeletons SF, and the left and right ends of ground legs 73, which are bent into a U-shape, are connected to the lower ends of the hanging pipes 72 via angle adjustment mechanisms 8 similar to those described above, so that the angle position of the ground ends of the ground legs 73 can be changed forward and backward relative to each hanging pipe 72.

For example, as shown in FIG. 4, a plurality of belt loops BL facing each other may be provided along the longitudinal direction of the outer peripheral walls of each pair of left and right side frames SF of the torso frame 3, upper arm frame 40, forearm frame FA, thigh frame 5, knee frame 6, and lower leg frame 7, for example, on the upper wall (which may be the left and right opposing walls, the lower wall, or the left and right outer walls, etc.), and a support belt SB may be stretched between the left and right belt loops BL. The support belt SB may have a fastening means such as a hook-and-loop fastener, a buckle, or a tie string, and may be stretched between the left and right belt loops BL so as to be freely attached and detached. Each support belt SB may be made of, for example, cotton, hemp, or other natural fibers, synthetic fibers such as polyamide or polyester, rubber, or may have a spring in the middle.

As shown in Figures 1 to 4, for example, the upper arm frame 40, arm leg 42, forearm frame FA, thigh frame 5, thigh leg 51, knee frame 6, lower leg frame 7 (foot frame), and lower leg leg 71 cross skeletons CF, as well as the skeleton parts that span between the left and right ends in the same manner, may be provided with cushion grips CG made of resin tubes or foam tubes for gripping.

The face frame FF is attached, for example, to the front end of the torso frame 3.
As shown in Figures 1 to 5 and 8(e), the face frame FF is, for example, gate-shaped and made up of a pair of left and right side rods FF1 made of square pipes and a cross rod FF2 made of square pipes suspended between the ends of each side rod FF1, with a forehead pad FP attached to the cross rod FF2, and support pieces FF3 are provided at the middle portions of each side rod FF1 that correspond to the left and right cheekbones when the forehead of a human body in a prone position is placed on the forehead pad FP, and left and right cheek pads CP are attached to each support piece FF3, and the base ends of each of the left and right side rods FF1 can be attached to the front end of the torso frame 3 via a position adjustment mechanism PM that also serves as an attachment/detachment mechanism, which will be described later.

As shown in Figures 7(a) and (b), the face frame FF is ladder-shaped and is fitted with a rectangular, flat, planar full-head pad FLP on top of it. The base ends of the left and right side rods FF1 of the face frame FF can be attached to the front end of the body frame 3 via a position adjustment mechanism PM that also serves as an attachment/detachment mechanism, which will be described later.

1 to 4, the position adjustment mechanism PM, which also serves as an attachment/detachment mechanism, has a pair of parallel, left and right rectangular tubular casings PM1 oriented in the front-to-rear direction provided on each lower wall at a position on the left and right (coinciding with the left and right side rods FF1) of the center between the left and right ends of the cross skeleton CF that is horizontally mounted near the front end of the body frame 3. A fixing hole is drilled in the peripheral wall of each casing PM1 from the bottom or side, and multiple positioning holes are drilled at intervals along the length of the face frame FF in the range near the base ends of the left and right side rods FF1. The left and right side rods FF1 of the face frame FF are inserted from the front into the left and right casing parts PM1 of the body frame 3, respectively, the amount of protrusion of the face frame FF is adjusted, the fixing holes are matched with the positioning holes, and temporary fixing screws (not shown) with operating knobs equipped with bolt and nut mechanisms are screwed into the fixing holes and the positioning holes that match them, so that the face frame FF is temporarily fixed.

The saddle frame SD is attached, for example, to the rear end of the body frame 3.
1 to 4, 7(a) and 7(d), the saddle frame SD is, for example, an inverted L-shape with a restricting rod SD2 erected at the rear end of an adjusting rod SD1 made of a square pipe, and a buttocks pad BP is fitted to the middle to rear end of the adjusting rod SD1 and the restricting rod SD2. The base end of the adjusting rod SD1 can be attached to the rear end of the body frame 3 via a position adjustment mechanism PM that also serves as an attachment/detachment mechanism.

The position adjustment mechanism PM, which also serves as an attachment/detachment mechanism, is provided with a square cylindrical casing PM1 facing the front-rear direction, for example, on the lower wall at the center between the left and right ends of the cross frame CF that is horizontally mounted near the rear end of the body frame 3. A fixing hole is drilled from the bottom or side of the peripheral wall of the casing PM1, and multiple positioning holes are drilled at intervals in the length direction in the range near the base end of the adjustment rod SD1 of the saddle frame SD. The adjustment rod SD1 of the saddle frame SD is inserted into the casing PM1 of the body frame 3 from the rear, the amount of protrusion of the saddle frame SD is adjusted, the fixing hole is aligned with the positioning hole, and temporary fixing screws (not shown) with operating knobs equipped with bolt and nut mechanisms are screwed into the fixing hole and the aligned positioning hole.

As shown in Figs. 1 to 4, 5, 7 to 9, the cushion equipment 9 has, for example, a rectangular flat forearm pad FAP attached to the left and right side skeletons SF and cross skeleton CF of the forearm frame FA. For example, a cushion sheet UBC is wrapped around and exteriorized on the upper arm frame 40, torso frame 3, thigh frame 5 and their respective support belts SB. The cushion sheet UBC may have mounting windows and operation windows corresponding to the face frame FF and saddle frame SD, for example. A similar cushion sheet LBC may also be wrapped around and exteriorized on the knee frame 6, lower leg frame 7 and their respective support belts SB. For example, each of the frames 40, 3, 5, 6, and 7 may be exteriorized with an independent cushion sheet UBC (LBC).

The cushioning device 9 may be made of, for example, a sheet, mat, pad, block, etc. made of foamed resin such as urethane, polyester, or rubber, and/or cotton, wool, wadding, or other elastic material, and may be covered with a cloth cover, with the adhesive surface provided with a means for attachment and detachment such as a hook-and-loop fastener, a hook and eye, a buttonhole and button, or a zipper.

As shown in Figures 2, 3, and 8(d) and (e), for example, left and right shoulder pads SP with a triangular cross section can be attached to the front end of the torso frame 3 at the portions corresponding to the left and right shoulders of the prone position human body, and further, a neck pad NP with a triangular cross section can be attached to the cushion sheet UBC at a position corresponding to the neck of the prone position human body between the left and right shoulder pads SP via a fastening means such as a hook and loop fastener or a hook. The width between the left and right ends of the neck pad NP can be set to a width suitable for expectoration procedures and for passing a tracheotomy tube, for example, 50 to 300 mm.

As shown in Fig. 1, Fig. 4, Fig. 8(c) and Fig. 8(d), for example, the support belt SB of the torso frame 3 at the part corresponding to the gastrostomy or enterostomy tube or stoma appliance of the abdomen of the prone position human body is not provided in advance, is removed, or is loosened, and the cushion sheet UBC at the part corresponding to the part is not provided in advance, is removed, or is loosened, and a communication space RS is formed that leads from above to the lower outside and/or the left and right outside of the part, and an abdominal pad AP that covers the communication space RS in a flat shape or in a top shape that can hold the abdomen of the prone position human body is removably fitted. For example, a chest pad CHP and a lumbar pad MPP are attached to the front and rear of the abdominal pad AP at positions corresponding to the chest and the lumbar, and the abdominal pad AP is removably attached so as to close the communication space RS between the chest pad CHP and the lumbar pad MPP.

As shown in Figures 1 to 5 and 7, for example, at the left and right outer sides of the chest of the prone human body on the torso frame 3, block-shaped trunk pads TP corresponding to the thickness of the chest are detachably attached to the cushion sheet UBC. Also, for example, at the left and right outer sides of the waist of the prone human body on the torso frame 3, block-shaped pelvic pads PP corresponding to the thickness of the waist can be detachably attached to the cushion sheet UBC. Also, on the outer periphery of the torso frame 3, a chest belt CB and a pelvic belt PB are attached, which are flexible enough to be temporarily fixed in an endless manner via a fastening means such as a hook and loop fastener or a hook, so as to hold the chest and buttocks of the prone human body.

For example, a block-shaped adduction prevention pad AC, which corresponds to the thickness of the thigh, is detachably attached to the cushion sheet LBC at a position on the inner side between the left and right thighs of the prone human body on the thigh frame 5. As shown in Fig. 1 to Fig. 5(b), the adduction prevention pad AC is, for example, a combination of two front and rear pads, and is formed into a block shape by joining the forward or rearward inclined surfaces of each pad, so that even when the positions of the two front and rear pads are moved forward and backward, the inclined portions of each pad maintain a constant overlap between the left and right width. In addition, the pads are completely separated, making it possible to avoid interference with the saddle frame SD and the buttocks pad BP.
At positions on the thigh frame 5 that correspond to the left and right outer sides of the thighs of a prone human body, block-shaped abduction prevention pads AB having a thickness equivalent to the thickness of the thighs are detachably attached to the cushion sheet LBC.

(prone position)
The prone position holding device 1 shown in Figures 1 to 7 and 8 can be changed into various shapes when the angle adjustment mechanism 8 between the torso frame 3, arm frame 4, upper arm frame 40, forearm frame FA, thigh frame 5, knee frame 6 and lower leg frame 7, the front height adjustment mechanism 43 of the arm leg 42 and the middle height adjustment mechanism 52 of the thigh leg 51 are adjusted, respectively, and can hold the supine human body P in various positions, such as the upper limbs bent and lower limbs bent position shown in Figure 6 (a), the upper limbs bent and lower limbs strongly bent position shown in Figure 6 (b), the upper limbs extended and lower limbs extended position shown in Figure 6 (c), the upper limbs bent and lower limbs extended position shown in Figure 6 (d), or the kneeling position shown in Figure 6 (e), and can be adjusted to hold the body in a different position depending on the user's condition and desire. In addition, as shown in Figure 9, it can be folded into a state that is easy to store and carry.
