Description

{A two-way sliding patient transfer device that can move critically ill patients with minimal movement}

The present invention relates to a bidirectional sliding patient transfer device capable of moving a critically ill patient while minimizing the movement thereof, and more specifically, to a bidirectional sliding patient transfer device capable of moving a critically ill patient while minimizing the movement thereof, wherein a sling can be positioned between the bed and the patient regardless of the direction of the bed when moving a patient lying on a bed, and when the patient is moved onto the patient transfer device, the patient transfer device can be transformed into a chair type for easy movement.

Typically, medical institutions or nursing homes use patient transfer lifts to transfer patients with limited mobility from beds to other means of transport, such as wheelchairs, or vice versa, from means of transport to beds.

Such patient transport lifts are classified as electric or non-electric depending on the driving method, and also as fixed or rotating depending on the degree of freedom of transport.

A fixed patient transport lift has a fixed structure so that the sling sheet on which the patient's body is placed does not rotate, and a rotary patient transport lift has a rotatable structure so that the sling sheet can rotate around a predetermined rotation axis.

At this time, the fixed patient transport lift has the advantage of having a stable structure and less anxiety felt by the patient, but there is a problem that the process of putting the patient on or off the sling seat is very inconvenient depending on the distance and angle from the patient's body.

In addition, in the case of a rotary patient transport lift, there is an advantage in that the process of putting a patient on or off a sling seat is convenient regardless of the distance or angle from the patient's body, but there is a problem in that the patient feels severe anxiety or suffers motion sickness during the process of rotating the sling seat.

That is, both the fixed and rotational types require the sling sheet to be inserted into the patient's back, but there was a problem that this process could cause pain to the patient, and when transported, the sling sheet could sag due to gravity, changing the patient's posture and causing great pain to the patient.

In addition, in the case of the above conventional technology, there was a problem that a lot of labor was required for guardians or caregivers to move and transport the patient.

The present invention relates to a bidirectional sliding patient transfer device capable of moving a critically ill patient while minimizing the movement thereof, and more specifically, to a bidirectional sliding patient transfer device capable of moving a critically ill patient while minimizing the movement thereof, wherein a sling can be positioned between the bed and the patient regardless of the direction of the bed when moving a patient lying on a bed, and when the patient is moved onto the patient transfer device, the patient transfer device can be transformed into a chair type for easy movement.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the attached drawings.

FIG. 1 is a perspective view showing a patient being moved by a two-way slide-type patient transfer device capable of moving a critically ill patient by minimizing the movement thereof according to the present invention, FIG. 2 is a perspective view showing a two-way slide-type patient transfer device capable of moving a critically ill patient by minimizing the movement thereof according to the present invention transformed into a chair shape, FIG. 3 is a perspective view showing a state in which a two-way slide-type patient transfer device capable of moving a critically ill patient by minimizing the movement thereof according to the present invention is slid onto a bed (10), and FIG. 4 is a plan view showing a state in which a two-way slide-type patient transfer device capable of moving a critically ill patient by minimizing the movement thereof according to the present invention is slid onto a bed (10).

As illustrated in FIGS. 1 to 4, the bidirectional slide-type patient transfer device according to the present invention, which can move a critically ill patient by minimizing his/her movement, can be changed into a bed form on which the patient can lie down and a chair form on which the patient can sit, and comprises a transfer unit (100) formed to operate a driving wheel (110) by a driving handle (120) to move the patient, a first transfer unit (200) and a second transfer unit (300) formed at the bottom and top of the transfer unit (100) respectively to slide toward a bed (10) on which the patient is lying and move the patient, a sling unit (400) formed in the first transfer unit (200) and having a sling sheet (420) wound inside and a plate (410) coupled to one end of the sling sheet (420) to be positioned on the bed (10), and a second transfer unit (300) formed on both sides inside, It is characterized by including a traction unit (500) that is provided with a traction belt (510) that can be connected to a plate (410) and inserts the plate (410) and sling sheet (420) between the patient and the bed (10) by winding the traction belt (510).

The driving handle (120) is characterized in that it can recognize the pushing or pulling direction with a sensor, and can move the patient by controlling the rotation direction and rotation speed of the driving wheel (110) according to the direction of force applied to the handle.

The first transfer unit (200) and the second transfer unit (300) are characterized by being able to slide in both directions to one side or the other with respect to the transfer unit (100), thereby allowing the sling unit (400) and the traction unit (500) to be moved to the bed (10) regardless of the position of the bed (10) on which the patient is lying.

The moving unit (100) is formed so as to be able to move toward a patient lying on a bed (10) and is formed so as to be able to change into a bed or chair shape so as to be able to move the patient lying down or sitting down.

The moving unit (100) that can be transformed into a bed and a chair has a number of joint structures, so that when the patient is moved from the bed (10) on which he or she is lying to the moving unit (100), the moving unit is formed in the shape of a bed, so that the patient's posture is not changed and the patient can be moved in the lying posture.

In addition, when the patient is moved to a lying position, the moving unit (100) can be transformed into a chair shape, and while the part where the patient's buttocks are formed is maintained, the backrest part can be rotated upward, and the leg rest part can be rotated downward, thereby transforming into a chair shape.

At this time, depending on the deformation of the backrest and leg rest areas, the edges on both sides of the area supporting the buttocks can be transformed into armrests on which the patient can place his or her arms, allowing the patient to assume a stable posture when sitting.

A plurality of driving wheels (110) are formed at the bottom of the moving unit (100) so that the patient can be moved in the same manner as an electric wheelchair while sitting, and in the case of a seriously ill patient, the moving unit (100) can be operated by control by a guardian, nursing assistant, or medical staff.

To this end, a driving handle (120) for operating a driving wheel (110) is provided on the rear of the backrest portion of the moving unit (100), and a sensor capable of measuring the direction of force applied to the driving handle (120) is provided so that the driving wheel (110) can be operated according to the direction of force applied to the driving handle (120).

For example, when the drive handle (120) is pushed forward while being gripped, the drive wheel (110) rotates and the moving unit (100) can move forward, and when the drive handle (120) is pulled, it can move backward.

In addition, if force is applied to only one of the left and right sides of the drive handle (120), the moving unit (100) can turn left or right, and if it is desired to stop, it can be stopped by applying force in the opposite direction of the moving direction.

Since the moving unit (100) can be moved according to the direction of the force applied again after being stopped, and the driving wheel (110) can be rotated according to the direction of the force applied to the driving handle (120) to move the moving unit (100), the guardian, nursing assistant, and medical staff can reduce the labor required to move the patient.

In addition, it is preferable that a battery be built into the moving unit (100) to supply power, and that a separate cylinder be provided to drive the moving unit (100) so that it can be transformed into a bed or chair shape.

In particular, it is preferable that a controller with a display and control buttons for controlling the operation of the moving unit (100) and checking the operating status be provided at the rear of the moving unit (100).

The operation structures of the first transfer unit (200) and the second transfer unit (300) are identical to each other, and are used when moving a patient lying on a bed (10) to the transfer unit (100) or when moving a patient lying on the transfer unit (100) to the bed (10).

The first transfer unit (200) is positioned at the bottom of the moving unit (100) and has a sling unit (400) coupled to the top, and the second transfer unit (300) is positioned at the top of the moving unit (100) and has a traction unit (500) coupled to the top.

The first transfer unit (200) and the second transfer unit (300) can slide in either one direction of the one side or the other side of the moving unit (100) to position the sling unit (400) and the traction unit (500) at the top and bottom of the bed (10) on which the patient is lying.

The sling unit (400) can be positioned under the feet of a patient lying on the bed (10) by the first transfer unit (200) and the second transfer unit (300), and the traction unit (500) can be positioned above the head of a patient lying on the bed (10).

Since the first transfer unit (200) and the second transfer unit (300) can slide in both directions from the moving unit (100) toward one side and the other side, when the moving unit (100) is positioned on the side of the patient's bed (10), the first transfer unit (200) and the second transfer unit (300) can position the sling unit (400) and the traction unit (500) on the bed (10) regardless of the direction in which the patient's bed (10) is positioned.

That is, when the first transfer unit (200) and the second transfer unit (300) slide in only one direction, it is necessary to adjust the position by matching the sliding direction of the first transfer unit (200) and the second transfer unit (300) formed on the transfer unit (100) according to the direction of the patient's bed (10), but the patient can be conveniently moved by the first transfer unit (200) and the second transfer unit (300) that can slide in both directions.

In addition, the first transfer unit (200) and the second transfer unit (300) can move the patient to the transfer unit (100) by sliding and returning to the transfer unit (100) while the patient is on the sling seat (420), and it is desirable to synchronize the rotation speeds of the first transfer unit (200) and the second transfer unit (300) during the transfer process.

The sling unit (400) is formed with a sling sheet (420) wound inside for moving a patient to a moving unit (100), and a plate (410) connected to one end of the sling sheet (420) is exposed to the outside of the sling unit (400).

The plate (410) is formed in a plate shape and is connected to a traction unit (500) and is used to position the patient on a sling sheet (420) while moving between the patient and the bed (10) by the traction unit (500).

The plate (410) may be formed in a state where it is inserted into one end of the sling sheet (420), and a pair of sling belts (411) may be formed on both edges of the plate (410) so as to be combined with the traction belts (510) formed in the traction unit (500).

The sling belt (411) is formed to be connected to the traction belt (510) with a clamp, and when the plate (410) is connected to the traction belt (510) by the sling belt (411), the traction unit (500) winds the traction belt (510) so that the plate moves between the patient and the bed (10), allowing the patient to be positioned on the sling sheet (420).

The traction unit (500) has a pair of traction belts (510) wound on both sides inside, and the pair of traction belts (510) are formed so that they can be combined with a pair of sling belts (411) located on one side and the left side of the plate (410), respectively.

When the traction unit (500) is operated to wind the traction belt (510) while the traction belt (510) is connected to the sling belt (411), the plate (410) connected to the traction belt (510) slowly moves from under the patient's feet to over the patient's head, and through this process, the sling sheet (420) connected to the plate (410) is positioned between the patient and the bed (10), allowing the patient to be positioned over the sling sheet (420).

It is desirable that the rotation speeds of the sling unit (400) and the traction belt (510) be synchronized with each other so that the tension of the traction belt (510) or the sling sheet (420) is maintained constant. When the patient is positioned on the sling sheet (420), the first transfer unit (200) and the second transfer unit (300) return to the moving unit (100), allowing the patient to be moved to the upper part of the moving unit (100) in the form of a bed and laid down.

Thereafter, the moving unit (100) can be transformed into a chair shape as needed, so that the patient can change his/her posture so that he/she is sitting, and the driving handle (120) of the moving unit (100) can be used to move the patient to a comfortable posture.

If necessary, the moving unit (100) may be equipped with a separate safety belt to prevent the patient from falling, thereby enabling the patient to be moved more safely.

The first transfer unit (200) and the second transfer unit (300) have the same structure, and the first transfer unit (200) is formed facing each other at the bottom of the transfer unit (100), and the second transfer unit (300) is formed facing each other at the top of the transfer unit (100).

Since the structures of the first transfer unit (200) and the second transfer unit (300) are the same, the structure and operation will be described based on the first transfer unit (200).

On the other side, a first drive roller (232) for changing the direction of a second wire (260) and a second drive roller (233) for changing the direction of a first wire (250) are provided, and a rack gear (234) is provided in the center to allow sliding in both directions by a first drive pinion (212) and a second drive pinion (213), and a first tension block (243) formed on the upper side of the drive pinion (230) and provided on the upper side to fix the first wire (250) and adjust the tension, and a second tension block (245) for fixing the second wire (260) and adjusting the tension are provided, so that a stand (240) is formed to slide from the drive pinion (230) by the first wire (250) or the second wire (260) depending on the direction of movement of the drive pinion (230).

In addition, it is characterized by further including a plurality of support rollers (224) formed on the upper front and rear sides of the support (220) and supporting the transporter (230) so that the transporter (230) can slide by rolling motion while in contact with the lower surface of the transporter (230), a plurality of transport rollers (242) formed on the lower front and rear sides of the stand (240) and forming the stand (240) so that the support rollers (224) can be inserted into one side and the transporter rollers (242) can be inserted into the other side, and a connecting end (231) formed on the lower front and rear sides of the transporter (230) in an ㅗ shape so that the support rollers (224) can be inserted into one side and the transport rollers (242) can be inserted into the other side.

The drive unit (210) is formed so that it can be fixed in position by being coupled to the moving unit (100), and is used to generate power and control the position of the moving unit (230) when the moving unit (230) formed on the first moving unit (200) slides in one direction and the other.

To this end, a drive motor (211) that generates rotational force using the power supplied from the moving unit (100) is provided inside the drive unit (210), and the rotational force generated from the drive motor (211) is formed to rotate the first drive pinion (212) and the second drive pinion (213) located at the center of one side and the other side of the drive unit (210) through a plurality of gears.

At this time, the first drive pinion (212) is formed to be directly connected and rotated by a plurality of gears connected to the drive motor (211), but the second drive pinion (213) located on the other side is formed to be rotated by a timing belt (214) that is connected to the side of the first drive pinion (212) and rotates.

The timing belt (214) has a number of gear teeth provided inside so that it can rotate by meshing with the gears formed on the sides of the first driving pinion (212) and the second driving pinion (213). By the timing belt (214), the first driving pinion (212) and the second driving pinion (213) are synchronized with each other so that the rotation direction and rotation amount can be controlled identically.

In addition, four detection switches (215) are provided on one side and the other side edges of the drive unit (210) to determine the position of the transport unit (230), and the detection switches (215) are provided with wheels on the top so that when the transport unit (230) is slid to one side and the other side by the first driving pinion (212) or the second driving pinion (213), the detection switches can be maintained in a state of being pressed by the transport unit (230) while making a rolling motion.

At the bottom of the transporter (230), a number of grooves are provided for the detection switch (215) to check the position of the transporter (230), and when the detection switch (215) is pressed, it protrudes upward when it reaches the groove, thereby enabling the position of the transporter (230) to be identified.

That is, the detection switch (215) is pressed when the transporter (230) slides, and when it reaches the groove of the transporter (230), the pressed detection switch (215) protrudes upward, thereby generating an operating signal, and the position of the transporter (230) can be determined based on this signal.

In addition, it is preferable that the grooves formed in the transporter (230) be such that the four detection switches (215) can determine the position at which the transporter (230) slides to one side or the other and the distance by which the transporter (230) has slid, so that the four detection switches (215) generate signals at different positions.

At this time, when the transporter (230) slides to one side, two detection switches (215) located on one side of the driving unit (210) are pressed, and then, by the grooves formed at different positions of the connecting end (231), the two detection switches (215) located on one side of the driving unit (210) protrude at different positions, enabling the distance of the transporter (230) to be determined.

The operation of the driving motor (211) can be controlled by the detection switch (215), and the transport member (230) can be prevented from being separated from the support member (220).

The support (220) is formed on the upper part of the driving member (210) and is used to support the transport member (230) so that it can slide only in one direction and the other direction of the driving member (210), and to enable the transport member (230) to slide smoothly by a plurality of support rollers (224).

The support (220) covers the upper part of the drive member (210) to prevent the drive member (210) from being exposed to the outside, and at the same time, a first drive hole (221) and a second drive hole (222) are provided so that the first drive pinion (212) and the second drive pinion (213) formed on the drive member (210) penetrate the support member (220) and are exposed to the outside.

The first driving hole (221) and the second driving hole (222) are provided in the center of one side and the other side of the support (220), and when connected to the driving member (210), the first driving pinion (212) and the second driving pinion (213) rotated by the driving motor (211) and the timing belt (214) protrude outward so that the transfer member (230) can come into contact with them.

The first drive pinion (212) and the second drive pinion (213) exposed by the first drive hole (221) and the second drive hole (222) come into contact with the rack gear (234) formed at the bottom of the transfer plate (230) so that the transfer plate (230) can slide in one direction and the other direction.

In addition, in order to enable the conveyor (230) to be restrained and slid in one and the other directions of the support (220), support members (223) formed in one and the other directions are protruded from the upper front and rear sides of the support member (220), and a plurality of support rollers (224) are formed at regular intervals on the outer surface of the support member (223).

The support roller (224) is inserted into the connecting member (231) formed at the bottom of the transport member (230) to restrict the transport member (230) so that it can only slide in one direction and the other direction of the support member (220), and friction and noise generated when the transport member (230) slides due to the rolling movement of the support roller (224) can be reduced.

In addition, a plurality of detection holes (227) are formed on one side and the other side edge of the support (220) so that four detection switches (215) can protrude from the upper part of the support (220), and the detection switches (215) are maintained in a state of protruding from the upper part of the support (220) through the detection holes (227) and can generate a signal when pressed or protruded by the transport member (230).

In addition, a first fixing block (225) and a second fixing block (226) are provided on the lower side and the other side of the transporter (230) to fix the first wire (250) and the second wire (260), and the first wire (250) and the second wire (260) pass through the transporter (230) and are connected to the stand (240) so that the stand (240) can slide from the transporter (230).

At this time, it is preferable that the first fixed block (225) and the second fixed block (226) are formed to be staggered toward the front and rear of the support (220) so that the first wire (250) and the second wire (260) do not come into contact with each other.

Through this, the stand (240) can be slid in multiple stages by the first wire (250) or the second wire (260) along the direction in which the transport unit (230) slides, and by this multi-stage sliding, the length of the first transport unit (200) can be shortened while the total sliding length can be extended.

The conveyor (230) formed on the upper part of the conveyor (230) is provided with a connecting member (231) formed in the shape of the letter ㅗ on the lower front and rear sides, and when a support roller (224) is inserted in the inner direction of the connecting member (231), the conveyor (230) can only slide in one direction and the other direction of the support member (220).

In addition, the support roller (224) is coupled between the transport member (230) and the connecting member (231) to perform rolling motion, thereby reducing frictional force and noise generated when the transport member (230) slides, thereby allowing the transport member (230) to slide stably.

A rack gear (234) formed from one side to the other side is provided at the center of the conveyor belt (230). The rack gear (234) is meshed with the first driving pinion (212) and the second driving pinion (213) so as to move the conveyor belt (230) in one or the other direction along the rotational direction of the first driving pinion (212) and the second driving pinion (213).

At this time, in the initial state where the transfer plate (230) is positioned on top of the support plate (220), both the first drive pinion (212) and the second drive pinion (213) are engaged, and when the transfer plate (230) is moved in one or the other direction, it can slide by engaging with the first drive pinion (212) or the second drive pinion (213).

It is preferable that the transport member (230) that is slid by the first driving pinion (212) or the second driving pinion (213) slides only to a position where the rack gear (234) is not separated, and this position can be controlled by a detection switch (215) formed on the driving member (210).

In addition, a first drive roller (232) and a second drive roller (233) are provided on one side and the other side of the conveyor (230) to change the rotational direction of the first wire (250) and the second wire (260), and the first drive roller (232) and the second drive roller (233) are formed to be staggered toward the front and rear of the conveyor (230).

This is to prevent the first wire (250) and the second wire (260) from coming into contact with each other and causing interference when they intersect, and the first drive roller (232) and the second drive roller (233) can move the first wire (250) and the second wire (260), which intersect each other at the upper part of the support (220), to the upper part of the transfer plate (230).

The first wire (250) and the second wire (260) can be positioned on the upper side of the transport plate (230) by the first driving roller (232) and the second driving roller (233), and can move to the upper side of the stand (240) while intersecting each other, and can be fixed by being combined by the first tension block (243) and the second tension block (245) formed on the upper side of the stand (240).

The stand (240) is formed so that a sling unit (400) or a traction unit (500) can be combined at the top, and the sling unit (400) or the traction unit (500) can be positioned on the bed (10) by sliding it a second time from the transport stand (230) by the first wire (250) or the second wire (260).

The first transfer unit (200) is shown as having a sling unit (400) attached to it, but the second transfer unit (300) is shown as having a towing unit (500) attached to it.

A transfer stage (241) is protruded from the lower front and rear of the stand (240), and a number of transfer rollers (242) are formed at regular intervals on the inner surface of the transfer stage (241).

The transfer roller (242) is connected to the outer surface of the connecting member (231) formed on the transfer plate (230) and is restricted so that it can slide only in one direction and the other direction of the transfer plate (230), thereby reducing friction and noise generated when the stand (240) slides by the support roller (224), thereby allowing the stand (240) to slide stably.

The first tension block (243) and the second tension block (245) formed on the upper part of the stand (240) are formed so as to fix the ends of the first wire (250) and the second wire (260), respectively, and the tension of the first wire (250) and the second wire (260) can be adjusted using the first adjusting screw (244) and the second adjusting screw (246).

The first adjusting screw (244) and the second adjusting screw (246) can change the positions of the first tension block (243) and the second tension block (245) by moving in the front and rear directions according to the direction of rotation, and the tension of the first wire (250) and the second wire (260) can be changed according to the changed positions.

When the transporter (230) is slid, the stand (240) can be slid a second time in accordance with the direction in which the transporter (230) is slid by the first wire (250) and the second wire (260).

The coupling structure of the first wire (250) and the second wire (260) can be expressed as shown in FIG. 7, and one end of the first wire (250) is coupled to the first fixing block (225) formed on one side of the lower portion of the support (220), and one end of the second wire (260) is coupled to the second fixing block (226) formed on the other side of the lower portion of the support (220).

Thereafter, the first wire (250) coupled to the first fixed block (225) is moved upwards on the support (220) by a hole formed on one side of the support (220), and the second wire (260) coupled to the second fixed block (226) is moved upwards by a hole formed on the other side of the support (220).

Thereafter, the first wire (250) moves to the upper part of the transfer plate (230) through the second drive roller (233) of the transfer plate (230) formed on the upper part of the support (220), and the second wire (260) moves to the upper part of the transfer plate (230) through the first drive roller (232) of the transfer plate (230), so that their directions intersect for the first time.

The first wire (250) moves to the upper part of the stand (240) through a hole formed on one side of the stand (240), and the second wire (260) moves to the upper part of the stand (240) through a hole formed on the other side of the stand (240), so that their directions can intersect each other twice.

The other end of the first wire (250) transferred to the upper part of the stand (240) is connected to the first tension block (243) formed on one side of the upper part of the stand (240), and the other end of the second wire (260) can be connected to the second tension formed on the other side of the upper part of the stand (240) and fixed.

When the transporter (230) is slid by the first wire (250) and the second wire (260) in this cross-shaped manner, the first wire (250) and the second wire (260) can slide the stand (240) a second time along the sliding direction.

FIG. 8 is a side view showing the sliding structure of the transfer unit of a bidirectional slide-type patient transfer device capable of moving a critically ill patient with minimal movement according to the present invention, and FIGS. 9 and 10 are side views showing the bidirectional sliding of a bidirectional slide-type patient transfer device capable of moving a critically ill patient with minimal movement according to the present invention.

As illustrated in FIGS. 8 to 10, the first wire (250) of the bidirectional slide-type patient transfer device capable of moving a seriously ill patient while minimizing the movement of the patient according to the present invention is connected in a cross-like manner toward one side of the support (220), the other side of the transfer table (230), and one side of the stand (240), and the second wire (260) is connected in a cross-like manner toward the other side of the support (220), one side of the transfer table (230), and the other side of the stand (240), so that the stand (240) is slid from the transfer table (230) by the first wire (250) or the second wire (260) depending on the sliding position of the transfer table (230).

As shown in Fig. 8, when the driving member (210), the support member (220), the transfer member (230), and the stand (240) are separated from each other, the first wire (250) and the second wire (260) are configured to first intersect each other in an X shape at the upper part of the support member (220) and secondly intersect each other in an X shape at the upper part of the transfer member (230).

Through this, the first wire (250) is connected to the second drive roller (233) formed on one side of the support (220) and the other side of the transfer plate (230) through the first fixing block (225), and to the first tension block (243) formed on one side of the stand (240), and the second wire (260) is connected to the first drive roller (232) formed on the other side of the support (220) and the one side of the transfer plate (230), and to the second tension block formed on the other side of the stand (240) through the second fixing block (226).

The first wire (250) and the second wire (260) connected in this manner are formed to intersect each other without contacting each other, and when the transfer member (230) is moved to one side or the other side by the first drive pinion (212) and the second drive pinion (213) formed on the drive member (210), the holder (240) can be slid a second time in the direction in which the transfer member (230) is slid by the first wire (250) or the second wire (260).

As shown in Fig. 9, when the driving member (210) slides the transfer member (230) in the other direction, the rack gear (234) formed at the lower part of the transfer member (230) can be slid to the other side of the support member (220) by the second driving pinion (213).

At this time, when the transporter (230) slides to the other side of the supporter (220), the length of the first wire (250) from the first fixed block (225) to the second drive roller (233) becomes longer, and the length from the second drive roller (233) to the first tension block (243) becomes shorter, allowing the stand (240) to slide in multiple stages in the other direction of the transporter (230).

In this case, the length of the second wire (260) from the second fixed block (226) to the first driving roller (232) becomes shorter, and the length from the first driving roller (232) to the second tension block (245) becomes longer, so that when the stand (240) slides by the first wire (250), interference by the second wire (260) does not occur.

As shown in Fig. 10, when the driving member (210) slides the transfer member (230) in one direction, the rack gear (234) formed at the bottom of the transfer member (230) can be slid to one side of the support member (220) by the first driving pinion (212).

At this time, when the transporter (230) slides to one side of the supporter (220), the length of the second wire (260) from the second fixed block (226) to the first drive roller (232) becomes longer, and the length from the first drive roller (232) to the second tension block (245) becomes shorter, allowing the stand (240) to slide in multiple stages in one direction of the transporter (230).

In this case, the length of the first wire (250) from the first fixed block (225) to the second drive roller (233) becomes shorter, and the length of the first wire (250) from the second drive roller (233) to the first tension block (243) becomes longer, so that when the stand (240) slides by the second wire (260), interference by the first wire (250) does not occur.

In the above manner, the conveyor (230) can be slid in one direction and the other direction by the rack gear (234) and the first driving pinion (212) or the second driving pinion (213), and the stand (240) can be slid in multiple stages in one direction or the other direction from the upper portion of the conveyor (230) by the first wire (250) or the second wire (260).

As the transport unit (230) and the stand (240) slide in multiple stages, the overall length of the first transport unit (200) can be reduced, and the sliding length can be doubled.

Figure 11 is a drawing showing the structure of a sling unit (400) of a two-way slide-type patient transfer device capable of moving a critically ill patient with minimal movement according to the present invention.

As shown in Fig. 11, the sling unit (400) of the bidirectional slide-type patient transfer device capable of moving a seriously ill patient by minimizing the movement according to the present invention comprises: a sling swivel (440) that is connected to the other end of a sling sheet (420) to roll up or roll out the sling sheet (420) according to the rotation direction; a sling motor (430) formed to be able to rotate the sling swivel (440); a sling tension bar (450) formed on the front of the sling swivel (440) and formed to be raised and lowered by a spring to adjust the tension of the sling sheet (420); and a sling tension detection sensor (470) positioned on each side of the sling tension bar (450) to control the operation of the sling motor (430) according to the lowering position of the sling tension bar (450) to adjust the tension of the sling sheet (420). It is characterized by being formed on the front of the sling tension bar (450) and comprising a sling support bar (460) that supports the position of the sling sheet (420) when the sling sheet (420) is wound or unwound.

The sling unit (400) is formed to be able to roll up or roll down the sling sheet (420), and is used to position the patient on the sling sheet (420) when moving the patient, and to adjust the tension of the sling sheet (420) when the patient is moved so that the patient is moved in a stable position.

To this end, the sling unit (400) is provided with a sling swivel (440) formed so that the other end of the sling sheet (420) can be wound or unwound by being connected, and the sling swivel (440) is connected to the sling motor (430) through a sling gear (431) so that the direction of rotation can be switched according to the rotational direction of the sling motor (430).

At this time, it is preferable that the sling swivel (440) be formed with fastening holes at regular intervals so that one end of the sling sheet (420) can be fastened and fixed.

A sling tension bar (450) that moves up and down is provided on the front of the sling swivel (440) to measure the tension that occurs when the sling sheet (420) is rolled up or rolled out, and a coil spring is provided on each of the lower ends of both sides of the sling tension bar (450), so that when the sling tension bar (450) is lowered, the coil spring is compressed and the sling tension bar (450) can be returned to its original position by the restoring force.

On both sides of the sling tension bar (450), a sling tension detection sensor (470) is provided to determine the state in which the sling tension bar (450) is lowered. The sling tension detection sensor (470) is provided with a roller on the upper side so that rolling movement is possible on the contact surface when the sling tension bar (450) is lowered, and is configured so that when the sling tension bar (450) is lowered, it is pressurized and a switch is operated.

Through this sling tension detection sensor (470), the lowered state of the sling tension bar (450) can be confirmed, and the rotation speed or operating state of the sling motor (430) can be controlled based on the tension generated when the sling sheet (420) is wound or unwound.

In addition, when a patient is positioned on the sling sheet (420), the sling swivel (440) can be rotated to ensure that the sling sheet (420) is kept taut, thereby winding the sling sheet (420). The tension generated at this time can be detected by the sling tension detection sensor (470), thereby enabling the tension state of the sling sheet (420) to be determined.

The sling support bar (460) is formed on the front of the sling tension bar (450) and is used to support the position when the sling sheet (420) is rolled up or unrolled by allowing the sling sheet (420) to pass between the two bars.

The sling support bar (460) can limit the left-right and up-down positions of the sling sheet (420), and the sling sheet (420) can be unwound or wound sequentially by passing through the sling swivel (440), the sling tension bar (450), and the sling support bar (460).

Figure 12 is a drawing showing the structure of a traction unit (500) of a two-way slide-type patient transfer device capable of moving a critically ill patient with minimal movement according to the present invention.

As shown in Fig. 12, the traction unit (500) of the bidirectional slide-type patient transfer device capable of moving a seriously ill patient by minimizing the movement according to the present invention comprises: a traction turntable (530) in which a pair of traction belts (510) are respectively connected to one side and the other side to take in or take out the traction belt (510) according to the rotation direction; a traction motor (520) formed to rotate the traction turntable (530); a traction tension bar (540) formed on the front side of the traction turntable (530) and formed to be raised and lowered by a spring to adjust the tension of the traction belt (510); a traction tension detection sensor (560) positioned on each side of the lower portion of the traction tension bar (540) to control the operation of the traction motor (520) according to the lowered position of the traction tension bar (540) to adjust the tension of the traction belt (510); and a traction tension sensor (560) located on the front side of the traction tension bar (540). It is characterized by being formed with a traction support bar (550) that supports the position of the traction belt (510) when the traction belt (510) is wound or unwound.

The traction unit (500) is formed to be able to wind or unwind the traction belt (510), and when the plate (410) of the sling unit (400) is positioned at the bottom of the bed (10), the traction belt (510) is unwound to extend its length so as to be combined with the sling belt (411) formed on the plate (410), and the traction belt (510) combined with the sling belt (411) is wound, thereby allowing the plate (410) to pass between the patient and the bed (10).

When the plate (410) passes between the patient and the bed (10), the sling sheet (420) connected to the plate (410) is positioned between the patient and the bed (10), thereby enabling the patient to be moved by positioning it over the sling sheet (420).

To this end, the traction unit (500) is provided with a traction turntable (530) that is formed so that the ends of a pair of traction belts (510) can be wound or unwound simultaneously by connecting them to one side and the other side so that they can be combined with sling belts (411) formed on both sides of the plate (410), and the traction turntable (530) is connected to the traction motor (520) through a traction gear (521) so that the direction of rotation can be switched according to the direction of rotation of the traction motor (520).

At this time, it is preferable that the towing swivel (530) be provided with fastening holes on both sides so that the ends of the towing belt (510) can be fastened and secured.

A traction tension bar (540) that moves up and down is provided on the front of the traction turntable (530) to measure the tension generated when the traction belt (510) is wound, and a coil spring is provided on each of the lower sides of the traction tension bar (540). When the traction tension bar (540) is lowered, the coil spring is compressed and the traction tension bar (540) can be returned to the original position by the restoring force.

On both sides of the traction tension bar (540), a traction tension detection sensor (560) is provided to determine the state in which the traction tension bar (540) is lowered. The traction tension detection sensor (560) is provided with a roller on the upper side so that rolling movement is possible on the contact surface when the traction tension bar (540) is lowered, and is configured so that when the traction tension bar (540) is lowered, it is pressurized and a switch is operated.

Through this traction tension detection sensor (560), it is possible to check the lowered state of the traction tension bar (540), and the rotation speed or operating state of the traction motor (520) can be controlled based on the tension generated when the traction belt (510) is wound and pulls the plate (410) and the sling sheet (420).

In addition, when a patient is positioned on the sling sheet (420), the traction swivel (530) can be rotated to ensure that the sling sheet (420) is kept taut so that the traction belt (510) can be wound, and the tension generated at this time can be detected by the traction tension detection sensor (560) to determine the tension state of the sling sheet (420).

At this time, since the traction belt (510) is connected to the sling sheet (420) through the plate (410), the sling tension detection sensor (470) and the traction tension detection sensor (560) can have similar tension values, and if the tension value of one side is larger or smaller, it can be determined that the plate (410) is caught between the patient and the bed (10).

The traction support bar (550) is formed on the front of the traction tension bar (540) and is used to support the position when the traction belt (510) is wound or unwound by allowing the traction belt (510) to pass between the stand (240) and the traction support bar (550).

The traction belt (510) can be restricted in the left-right and up-down directions through the traction support bar (550), and the traction belt (510) can be unwound or wound sequentially by passing through the traction turntable (530), the traction tension bar (540), and the traction support bar (550).

As described above, according to the bidirectional slide-type patient transfer device capable of moving a critically ill patient by minimizing the movement of the patient according to the present invention, regardless of the position of the bed on which the patient is lying, when the patient transfer device is positioned parallel to the bed, the sling sheet can be positioned by sliding to the upper and lower parts of the bed, and the sling sheet can be automatically pulled from the patient's feet to the head so that the patient can be moved from a lying state to the sling sheet, and when the patient transfer device that has slid to the upper and lower parts of the bed returns to its original position, the patient can be moved to the patient transfer device by sliding horizontally at the same height as the bed, and since the patient transfer device can be transformed into a bed and a chair form, when moving the patient, the patient can be moved in a lying state like a bed, and when the movement of the patient is completed, the patient can be transformed into a chair form and then moved electrically.

As described above, the present invention has been described with reference to preferred embodiments, but it will be understood by those skilled in the art that various modifications or variations may be made to the present invention without departing from the technical idea and scope described in the claims of the present invention.
