Description

The present invention relates to a transfer device. The transfer machine of this invention makes it possible for the person requiring assistance to easily stand up (stand up) and sit down (sitting down) while utilizing the remaining ability of the person requiring assistance as much as possible when transferring the person requiring assistance. It is a device that facilitates the transfer of a person requiring assistance by assisting the patient.

[Explanation of terms]
First, the terms used in this specification will be explained.
“Assistance” refers to those who are physically or mentally handicapped and have difficulty in carrying out their daily lives. It is to provide various types of assistance.
“Persons requiring assistance” are those who require assistance in all or part of basic daily activities such as moving, bathing, toileting, eating, dressing, and washing due to a physical or mental disability. be.
A “caregiver” is a person who assists a person requiring assistance.
"Transfer" refers to, for example, the action of transferring from a bed to a wheelchair or from a wheelchair to a toilet seat of a Western-style toilet. Recently, there are also portable toilets (simple flush toilets) with a hot water shower function, so transferring from a bed to a portable toilet is also included in transfer. A portable toilet with a hot water shower function is placed near the bed, but its placement position is within a certain range around the bed. This is because the portable toilet of this type is connected to a water supply hose and the like, so the arrangement position is limited to the range in which the hose can be routed.

"Difference" generally refers to the dimensional difference between the height to the top of a desk or table and the height to the seat of a chair. In accordance with this, in this specification, the dimensional difference between the height to the upper plate of the transfer device according to the present invention and the height to the upper surface (seat surface) of, for example, a bed, a wheelchair, or a portable toilet is referred to as "different size." It says.
"Base of support (BOS)" means "an area (range) for supporting the weight of a person". For example, as shown in FIG. 1(a), when a person is in a standing posture, the base of support is the range surrounding the dotted soles in the figure, as shown in FIG. 1(b). be. Also, for example, when a person is in a standing posture with a cane on, the range encompasses both the tip of the cane on the floor and the sole of the foot. When a person sits on a chair and is in a sitting posture with the buttocks in contact with the seat surface of the chair and the soles of the feet in contact with the floor surface, the part of the buttocks that is in contact with the seat surface of the chair and the floor surface It is a range that surrounds the contacting sole.

[Rising motion based on base of support theory]
Next, the theory of the base of support, which optimally utilizes the relationship between the "base of support" and the "human center of gravity" to enable a person to stand up from a seated state with the least burden, will be described. This base of support theory is a theory known in the world of rehabilitation and ergonomics.

In FIG. 2, the point where the center of gravity GL of the human body center of gravity G and the floor F intersect is called the pressure center point P. As shown in FIG. As shown in FIG. 2, when a person sits on the edge of the bed B, puts his/her feet on the floor F, and is in a sitting posture in which the upper half of the body is stretched straight upward, the center of pressure P and the position of the sole of the person's foot are the same. are separated from each other, and cannot stand up in this state.

On the other hand, as shown in FIG. 3, when a person is sitting on the edge of the bed B and puts his or her feet on the floor F, the buttocks are shifted to the front position (the left position in the figure) and the heels of the feet are placed. When the upper half of the body is tilted forward by bringing the upper body closer to the bed B, the pressure center point P enters the range surrounding the soles of the feet. As shown in FIG. 3, after the upper body is tilted forward and the pressure center point P is in the range surrounding the soles of the feet, the force required to stand up is small if the buttocks are lifted and then the person stands up. test.

Further developing the description based on FIGS. 2 and 3, a series of motion states in which a person can stand up from a sitting state with the least burden will be described with reference to FIG. In addition, in FIG. 4, BOS indicates the base of support.

The state of FIG. 4(a) is the same state as that of FIG. 2, the pressure center point P is at the rear position (right side position in the figure) of the base of support BOS, and the person is stably at the end of the bed B. Stable and sitting.
The state of FIG. 4(b) is the same as that of FIG. 3. The buttocks are shifted forward (to the left in the figure), the heels are brought closer to the bed, the upper body is tilted forward, and the center of gravity G of the body is shifted forward. is moving to By doing so, the pressure center point P moves to the front position and comes to the position where the sole is placed on the base of support BOS. When the posture shown in FIG. 4(b) is taken, the buttocks can be easily lifted, followed by a standing motion.

In the state of FIG. 4(c), the buttocks are lifted from the bed B while maintaining balance while the center of pressure P is kept at the sole position.
In the state of FIG. 4(d), the body's center of gravity G is moved upward using the force of the legs while raising the upper body in a balanced state.
In the state shown in FIG. 4(e), the whole body is stretched and is in a stable standing posture.

By successively performing the actions shown in FIGS. 4(a) to 4(e) in this way, the user can stand up from a seated state with the least burden. FIG. 4 shows a state in which a physically healthy person is standing up. By applying such a standing motion to a person requiring assistance, the need for assistance can be reduced. That is, when the person requiring assistance whose leg strength is weakened is to stand up, the person is assisted so that the posture of the person requiring assistance is sequentially changed to the postures shown in FIGS. 4(a) to 4(e). to stand up. In this way, the labor of the caregiver is reduced, and the care-requiring person can stand up safely and easily.

[Current situation of nursing care]
In care facilities such as care facilities and at-home care, people who require care mainly spend their lives on the bed. For this reason, when a person requiring assistance who has difficulty walking independently moves to a toilet, bathroom, dining room, rehabilitation training room, etc., the person requiring assistance must be assisted by a caregiver to transfer from the bed to the wheelchair. Moves to the toilet, dining room, etc. in a wheelchair. The caregiver must assist the person in need of assistance in transferring from bed to wheelchair, from bed to portable toilet, from wheelchair to toilet seat, and so on. Furthermore, the caregiver has to carry out many tasks such as moving and transporting the wheelchair on which the person requiring care is on, dressing and undressing, excretion processing, and meal assistance. In addition, for example, the number of times a person requiring assistance uses the toilet to excrete urine or feces, or the number of times a person requiring assistance goes to the cafeteria is multiple times a day. It must be done frequently. Due to the excessive burden and effort imposed on caregivers, caregivers often experience pain in various parts of the body, such as the lower back, knees, back, arms, and neck, and low back pain becomes chronic. I am very busy with various care work. Problems such as the onset of low back pain in caregivers have become a major social issue.

Here, a brief description will be given of a general conventional assistance operation for manually transferring a person requiring assistance, who has a certain degree of residual ability as a physical function, from a bed to a wheelchair.
(1) First, place the wheelchair near the bed.
(2) Put the person requiring assistance N into a seated position sitting on the edge of the bed.
(3) As shown in FIG. 5, have the person requiring assistance N hug the person H while sitting. The caregiver H picks up the person requiring assistance N, and rotates together with the person requiring assistance N who is picked up to turn the buttocks of the person requiring assistance N toward the wheelchair.
(4) As shown in FIG. 6, the caregiver H slowly lowers the person N to sit on the seat of the wheelchair while holding the person N in their arms. When the person requiring assistance N sits on the seat surface of the wheelchair, the person requiring assistance N holds the arm support of the wheelchair with his/her hands, maintains the posture by the strength of his arms, and sinks his body little by little, thereby stabilizing. You can sit comfortably while maintaining good posture.

Next, as another example of the assistance action, a brief description will be given of an assistance action of manually moving a person requiring assistance from a wheelchair to a toilet seat to excrete. This kind of so-called “toilet assistance” requires two assistants (the first assistant and the second assistant) to ensure safety when assisting a person requiring assistance who has decreased cognitive ability or physical function. 2 caregiver).

(1) The first caregiver picks up the person requiring assistance sitting in the wheelchair and transfers the picked-up person requiring assistance from the wheelchair to the toilet seat. At this time, the person requiring assistance first sits on the toilet seat while wearing a lower garment (trousers, diaper, underpants, etc.) on the lower half of the body.
(2) The first caregiver picks up the person requiring care and causes the person requiring care to stand up from the toilet seat. Furthermore, the first caregiver holds the underarm of the person requiring assistance and puts the person requiring assistance in a standing position. At this time, the person requiring assistance holds the handrail installed on the wall of the toilet and holds the trunk. The person's upper body is tilted forward, and the first caregiver takes off the person's lower garment. In addition, if the residual ability of the person requiring assistance is low, or if the degree of dementia is advanced, there is a risk that the person will let go of the handrail and fall. , While the first caregiver secures the person's standing posture, the second caregiver removes the lower garment of the person requiring care.
(3) Next, the first caregiver lowers the person requiring care while holding the person requiring care, and sits the person requiring care who has removed the lower garment on the toilet seat.
(4) Have the baby excrete.
(5) After excretion, the first caregiver holds the care-requiring person in his arms and makes him/her stand up, secures the care-requiring person's standing posture, and further tilts the upper body of the care-requiring person forward. Then, the second caregiver performs post-excretion treatment such as genital washing (wiping the lower half of the body), and puts the lower garment on the care-requiring person who is in a standing posture while grasping the handrail.
(6) After that, the first caregiver puts the person requiring care on the wheelchair while holding the person.

In addition to the above-mentioned toilet assistance, in various situations such as transferring from a bed to a wheelchair, or from a bed to a portable toilet, the person requiring assistance is required to stand up from a sitting posture to a standing posture (stand-up motion). ) or perform a sitting motion (sitting motion) from a standing posture to a sitting posture. In the nursing care field, assistance for such standing and sitting actions frequently occurs.

[Conventional transfer machine]
Therefore, various transfer devices have been conventionally developed in order to reduce the burden on the caregiver and assist the person requiring care in standing up and sitting down.

FIG. 7 shows a state in which the caregiver H uses the conventional transfer device 01 to raise the care-requiring person N sitting on the edge of the bed B. As shown in FIG. The person requiring assistance N takes a seated posture at the end of the bed B, puts the soles of the feet on the footrest portion 02 of the transfer device 01 and puts the knees on the knee pads 03 . In this state, the caregiver H inserts the pair of arm portions 04 into both armpits of the person N requiring assistance. Next, the caregiver H moves the arm section 04 upward and forward by pushing down the push-up section 05 that applies the principle of leverage using the hands and feet. Then, with the knees pressed against the knee pads 03, both armpits of the person requiring assistance N are lifted upward and forward, and the upper body moves upward and forward while the opening angle of the knee joints widens. You can go and stand up.

When the conventional transfer machine 01 is used to perform a sitting action, the above-described action is reversed, so that the person requiring assistance N, who is in a standing position, is placed in a sitting position.

The transfer machine 01 shown in FIG. 7 is a type of device that lifts the side of the person N requiring assistance. There is also a type transfer machine. Further, as a conventional technology, there is a transfer machine of a type that lifts the person requiring care N by using an electric force, a spring force, or a gas damper force.

JP 2021-65517 A

By the way, not only the conventional transfer machine shown in FIG. 7, but also any conventional transfer machine, as shown in FIG. while the position of the sole of the foot and the pressure center point P are separated, that is, while the person requiring assistance N is in a posture that makes it difficult to stand up (the same posture as shown in FIGS. 2 and 4(a)). , the person requiring assistance N is forced to stand up. Therefore, a large force is required to make the person N requiring assistance stand up, and a large force is applied to the person N requiring assistance. Further, when the transfer device 01 shown in FIG. 7 is used, the knees of the person requiring assistance N are strongly pressed against the knee pads 03 . Since force and pressure are applied to the body of the person requiring assistance N in this way, the person requiring assistance N suffers a great burden and pain.

In addition, in transfer assistance using a conventional transfer machine, when the person requiring assistance N is seated (seated) from a standing posture to a sitting posture, the person requiring assistance N is forced to use his or her arms and hands, which have remaining ability. Since there is no need to support a support or the like, the person N who needs assistance may receive a great burden or pain on the body, or may feel uneasy.
That is, for example, as shown in FIG. 6, when the person requiring assistance N sits on the seat surface of the wheelchair, the person requiring assistance N grasps the arm support of the wheelchair with his/her hands and maintains his/her posture by the strength of his/her arms. By sinking the body little by little, you can sit comfortably while maintaining a stable posture. However, when the person requiring assistance N is seated (sitting) using a conventional transfer machine, the person requiring assistance N cannot use his/her hands and arms to maintain his/her posture. I feel pain and anxiety because I can't do anything while I leave it to (the transfer machine).

In view of the above-described conventional problems, the present invention is designed to make the sitting posture of the person requiring assistance similar to the ideal posture for standing up shown in FIGS. Assisting the person in standing up so that they can stand up on their own as much as possible, and allowing the person requiring assistance to support the trunk as much as possible with their own hands and arms when changing from a standing posture to a sitting posture, so that the person can sit down comfortably. It provides a transfer. That is, by applying the theory of the base of support explained with reference to FIG. To provide a transfer machine capable of allowing a person requiring care to be seated in a state deviated from the theory of the base of support when sitting from a standing posture to a sitting posture, and allowing the user to sit on the seat without anxiety.

It should be noted that the state of physical function and the degree of disability vary among persons requiring assistance. Persons requiring assistance who can use the transfer device of the present invention include, for example, those who have the physical function (residual ability) to perform the following actions even if they are slow, or those who need assistance It is intended for people who can perform the following actions with simple assistance from a person.
(a) Able to bend and straighten elbows, knees and hips.
(b) The sole of the foot can be placed on the floor.
(c) For example, when a person is sitting on the edge of a bed and puts his/her feet on the floor, he/she can stand up with a certain amount of assistance.
(d) In the sitting posture of (c), the sitting posture of sitting on a chair, etc., the upper half of the body can be tilted forward.
(e) In order to stabilize the trunk in a standing or sitting posture, the posture can be maintained and supported to some extent by the strength of the arms while holding a supporting member or the like with the hands.

The transfer machine according to the present invention for solving the above problems is
a base plate;
a rotating mechanism having a fixed portion fixed to the base plate and a rotating portion rotatably arranged on the fixed portion;
a turning plate fixed to the rotating portion of the rotating mechanism and capable of turning while maintaining a parallel state with respect to the base plate;

a rear grip portion disposed at a position rearwardly and downwardly of the rear edge of the upper plate and at a height position that can be gripped by a person standing on the swivel plate.

In addition, in the transfer machine of the present invention,
The upper plate is at a height position that does not contact the legs of a person who is in a sitting posture while putting his/her feet on the turning plate, and is in a sitting posture while putting his/her feet on the turning plate. It is positioned in the front-rear direction so that the legs and torso of the person do not come into contact when the person stands up from the sitting posture to the standing posture,
The upper surface of the upper plate is inclined so that the height gradually decreases from the rear to the front.
In addition, in the transfer machine of the present invention,
A positioning plate is arranged on the upper surface of the swivel plate for positioning the foot by contact with the tip of the foot when the person puts the foot on the swivel plate.

According to the transfer device according to the present invention, when transferring, the person requiring care can easily stand up using the so-called scale method, and can safely and comfortably sit down. Able to sit down. This greatly reduces the burden on the caregiver when transferring.

[How to use the transfer machine]
As an example of transferring using the transfer machine 1, an operation state in which the person requiring care N transfers from the bed B to the portable toilet PT will be described.

First, the caregiver prepares for the transfer. That is, the caregiver places the transfer device 1 next to the bed B so that the rear side of the transfer device 1 faces the bed B. As shown in FIG. In addition, the caregiver installs a portable toilet PT near the transfer machine 1 installed beside the bed B. - 特許庁In this manner, the bed B and the portable toilet PT are arranged at circumferentially displaced positions on the periphery of the transfer device 1. - 特許庁

Next, the person requiring assistance N does a standing motion (standing motion) by himself/herself. That is, by using the transfer device 1, the person N who needs assistance stands up (stands up) by himself from a state where he is sitting on the edge of the bed B. As shown in FIG. This operation procedure will be described with reference to FIGS. 11 to 13. FIG. 11 to 13, the person requiring assistance N is indicated by a chain double-dashed line. This standing motion can be easily performed according to the theory of the base of support by appropriately setting the difference (height dimensional difference) between the upper plate 20 of the transfer machine 1 and the upper surface of the bed B. This is an operation using a so-called differential scale method.

The transfer machine 1 is installed beside the bed B with the rear side of the transfer machine 1 on the bed B side, as shown in FIG. The person N requiring assistance sits on the edge of the bed B, lowers his/her legs, and puts them on the swivel plate 12 . Also, the person N requiring assistance adjusts the position of the foot so that the tip of the foot contacts the positioning plate 13 . By placing the foot on the swivel plate 12 with the tip of the foot in contact with the positioning plate 13 in this manner, the support base surface during use is appropriately set.

In addition, the person requiring assistance N places the forearm on the upper plate 20 while placing the elbow on the elbow receiving portion 21 . Furthermore, the person requiring assistance N grips the front grip portion G1 or the front grip portion G2 by hand. FIG. 11 shows a state in which the front grip portion G1 is gripped.

From the state shown in FIG. 11, the upper body of the person requiring assistance N is tilted forward while sitting. Then, since the upper plate 20 is tilted forward so that the height gradually decreases from the rear to the front, the posture similar to that shown in FIG. 3 and FIG. The buttocks of the patient can be easily lifted from the upper surface of the bed B, and the posture required for standing up can be reduced.

The person requiring assistance N moves the upper half of the body forward while lifting the buttocks while pulling the gripped front grip part G1 (or G2) toward the person. Then, the elbow held by the elbow receiving part 21 becomes just like a fulcrum of a lever, and the upper arm and shoulder move forward with the elbow as a fulcrum of rotation, thereby easily moving the upper body forward and upward. go. At this time, by extending the leg so as to widen the opening angle of the knee joint, the person requiring assistance N can easily stand up by himself as shown in FIG. The posture shown in FIG. 12 is the same posture as the posture shown in FIG. 4(c).

When the person requiring assistance N stands up from the posture shown in FIG. 12 so as to straighten his legs by the strength of his legs, as shown in FIG. G2), the elbow separates from the elbow rest 21 and floats upward, allowing the user to stand up.

After that, the care recipient N releases his/her hand from the front grip G1 (G2) and pulls back the upper half of the body, which has been tilted forward, so that the whole body is straightened upward, and assumes a standing posture. be able to. The person requiring care N, who is in the standing posture in this way, can maintain the standing posture stably standing on the turning plate 12 by gripping the auxiliary pipe 31 with the hand.

Next, a turning motion is performed by the caregiver. That is, as shown in FIG. 13, the person requiring assistance N stands up on the turning plate 12 while gripping the front grip portion G1 (G2), or the person requiring assistance N is holding the auxiliary pipe 31 while the turning plate 12 is being lifted. After standing up, the caregiver grips the front grip portions G1 and G2, the rear grip portion G3, the pipe member 30, and the like, and pulls the revolving plate 12 of the transfer machine 1 and the members above the revolving plate 12. Swirl (rotate in the horizontal plane). Then, when the back and buttocks of the person requiring assistance N face (face) the portable toilet PT, the turning of the turning plate 12 and the like is stopped.

Next, the person N requiring assistance performs a sitting motion (sitting motion) by himself/herself.
