Description

Technical Field

[0001] This invention relates to the field of medical transport device technology, and in particular to a medical transport bed that is easy to clean. Background Technology

[0002] A patient transport bed is a mobile device designed for the safe and efficient transfer of patients. Its core advantage lies in its movable conveyor belt structure, which significantly reduces the frictional resistance between the patient's body and the support surface. This allows medical staff to transfer patients more effortlessly and smoothly, effectively improving operational safety, significantly reducing the probability of secondary injury to the patient during transfer, and lowering the risk of musculoskeletal strain for medical staff from lifting patients. In actual use, because the conveyor belt comes into direct contact with the patient, it is easily stained with blood, medication, and other contaminants. Existing patient transport beds often have complex and tightly fixed conveyor belt designs, making them extremely difficult to disassemble and clean quickly, severely reducing the equipment's turnover efficiency. Summary of the Invention

[0003] This invention provides a medical transfer bed that is easy to clean, overcoming the disadvantages of existing transfer beds with conveyor belts, such as inconvenient disassembly of the conveyor belt leading to cleaning difficulties and low equipment turnover efficiency.

[0004] The technical implementation of the present invention is as follows: a medical convenient cleaning transfer bed, comprising: a frame and a bed board, the bed board being fixedly connected to the upper side of the frame, an electric roller and a guide belt being provided on the upper side of the bed board, the guide belt being used to carry the patient, and a power component being provided on the upper side of the bed board for providing power for the movement of the guide belt; The power assembly includes: two electric slide rails, two mounting seats, and two connecting seats. The electric slide rails are disposed on the upper side of the bed board, and sliders are disposed on the electric slide rails. The mounting seats are fixedly connected to the sliders on adjacent electric slide rails. The two mounting seats are used to mount the electric roller shaft. The connecting seats are disposed on the mounting seats. Magnetic rings are fixedly connected to the opposing sides of the mounting seats and adjacent connecting seats. There is a magnetic attraction between two adjacent magnetic rings. The electric roller shaft is in surface contact with the outer periphery of the guide belt. The opposing sides of the two connecting seats are jointly provided with a bearing component for maintaining the shape of the guide belt, so as to lock the relative position of the electric roller shaft and the guide belt.

[0005] Furthermore, the bearing assembly includes: two symmetrically distributed side support plates, a support roller, a main inner roller, a secondary inner roller, and a guide member. The support roller and the main inner roller are both disposed between the two connecting seats. The support roller and the main inner roller are rotatably connected to the two side support plates. The secondary inner roller is disposed on the opposite side of the two side support plates. The secondary inner roller is fixedly connected to the guide member. The guide belt is wound around the support roller and the guide member. The electric roller shaft is located between the support roller and the main inner roller.

[0006] Furthermore, it also includes: a plurality of support mechanisms disposed between the main inner roller and the auxiliary inner roller, the support mechanisms being located inside the guide belt, the support mechanisms being used to support the guide belt and switch between rigid and flexible support modes; the support mechanisms include: a main mounting cylinder, an auxiliary mounting cylinder, and a support plate, the main mounting cylinder being rotatably connected to the auxiliary inner roller, the auxiliary mounting cylinder being rotatably connected to the main inner roller, both the main mounting cylinder and the auxiliary mounting cylinder being hinged to the support plate, the support plate being in contact with the upper side of the guide belt, for providing support for the guide belt.

[0007] Furthermore, the main inner roller is slidably connected to a power knob, and the main inner roller is fixedly connected to a reset member. The reset member is used to squeeze the secondary mounting cylinder and make it rotate. The secondary inner roller is rotatably connected to the side support plate, and the guide member is used to squeeze the main mounting cylinder and make it rotate.

[0008] Furthermore, the main inner roller is slidably connected to a main locking member fixedly connected to the power knob. The main locking member is used to restrict the rotation of the main inner roller, the secondary mounting cylinder, and the reset member relative to the side support plate. The secondary inner roller is slidably connected to a secondary locking member. The secondary locking member is used to restrict the rotation of the secondary inner roller, the guide member, and the main mounting cylinder relative to the side support plate. The secondary locking member is fixedly connected to a limit plate. The side support plate is provided with a first limit groove near the secondary inner roller. The secondary inner roller is provided with a second limit groove. The guide member is provided with a third limit groove. The limit plate restricts the rotation of the secondary inner roller relative to the side support plate through the first limit groove, the second limit groove, and the third limit groove.

[0009] Furthermore, a support rod is fixedly connected to the lower side of the auxiliary mounting cylinder, and the support rod is used to support the guide belt.

[0010] Furthermore, both ends of the support rod are spherical.

[0011] Furthermore, the guide belt has raised ridges along its edge, and the electric roller shaft, the support roller, the guide member, and the reset member all have annular grooves at positions corresponding to the raised ridges of the guide belt.

[0012] Furthermore, the mounting base is rotatably connected to the connecting base, and a support block is fixedly connected to the side of the electric slide rail near the guide member, the support block being used to support the adjacent side support plate.

[0013] Furthermore, the side of the electric slide rail closest to the guide is rotatably connected to the bed board.

[0014] The beneficial effects of adopting the above technical solution are as follows: This invention utilizes the contact between the electric roller shaft and the outer periphery of the guide belt, and uses the connecting seat to lock the relative position of the electric roller shaft and the guide belt. When using the guide belt to transfer patients, the guide belt is kept in a taut state, which facilitates the transfer of patients. When it is necessary to remove the guide belt for cleaning, the relative position of the electric roller shaft and the guide belt is unlocked by controlling the connecting seat, so that the electric roller shaft loses its pressure on the guide belt, thereby making the guide belt change to a relaxed state, which facilitates the disassembly and cleaning of the guide belt and improves the efficiency of equipment turnover.

[0015] By switching between flexible and rigid support through the relative positions of the support plate and the guide strap, and adjusting the position of the corresponding support plate according to the patient's wound location and transport needs, flexible support is provided to the patient's wound to reduce the probability of the wound tearing due to compression, while rigid support is provided to the rest of the patient's body to ensure stability during transport.

[0016] The guide strap is supported by a support rod to keep it taut. When the position of the local support plate is adjusted, the support rod moves together and loses contact with the guide strap, making the guide strap more deformable in the local position. This further reduces the support effect of the guide strap on the patient's wound and lowers the probability of causing secondary damage to the patient's wound.

[0017] By utilizing the rotating connection between the electric slide rail and the bed board, the electric slide rail and the side support plate can swing as a whole. The electric slide rail and the hospital bed provide two-point support for the side support plate, avoiding the entire weight of the patient being borne by the electric slide rail. At the same time, shortening the length of the slider on the electric slide rail extends the movable distance of the side support plate, making it easier to carry and transfer the patient.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0022] Example 1

[0023] This embodiment provides a medical transport bed that is easy to clean, thereby improving the ease of disassembling and cleaning the transport bed.

[0024] See Figures 1 to 6A medical transport bed that is easy to clean includes: a frame 1 and a bed board 2. The height of the bed board 2 can be adjusted by the frame 1 (this is an existing structure and will not be described in detail here). The bed board 2 is fixed to the upper side of the frame 1. Handrails are provided on both the front and rear sides of the bed board 2. The handrails are an existing structure. When transporting patients, the handrails can swing to the lower side of the bed board 2. An electric roller 3 and a guide belt 9 are provided on the upper side of the bed board 2. The electric roller 3 consists of two end seats and rollers symmetrically distributed on the left and right. A power component for providing power for the movement of the guide belt 9 is provided on the upper side of the bed board 2.

[0025] See Figure 2 , Figure 3 and Figures 5 to 8 The power assembly includes two electric slide rails 10, two mounting seats 11, and two connecting seats 12. The two electric slide rails 10 are respectively located on the left and right sides of the upper side of the bed board 2. Each electric slide rail 10 has a slider. The mounting seats 11 are fixedly connected to the sliders on the adjacent electric slide rails 10. The two mounting seats 11 are used together to mount the electric roller shaft 3. Specifically, the two mounting seats 11 are fixedly connected to the end seats on the left and right sides of the electric roller shaft 3. The connecting seats 12 are located on adjacent mounting seats 11. The mounting seats 11 and the adjacent connecting seats 12 face each other. Each of the two connecting seats 12 is fixedly connected with a magnetic ring 13. There is a magnetic attraction between two adjacent magnetic rings 13. The connecting seat 12 and the mounting seat 11 are fixed by magnetic attraction, which makes it easy to remove the connecting seat 12. The electric roller 3 and the outer peripheral side of the guide belt 9 are in surface contact. The outer side of the roller of the electric roller 3 is provided with a rubber sleeve to increase the friction between the roller of the electric roller 3 and the guide belt 9. The opposing sides of the two connecting seats 12 are provided with a bearing component to maintain the shape of the guide belt 9, so as to lock the relative position of the electric roller 3 and the guide belt 9.

[0026] The above setup enables the electric roller 3 to contact the outer periphery of the guide belt 9, and the connecting seat 12 to lock the relative position of the electric roller 3 and the guide belt 9. When using the guide belt 9 to transfer patients, the guide belt 9 is kept taut, which facilitates the transfer of patients. When it is necessary to remove the guide belt 9 for cleaning, the connecting seat 12 is controlled to unlock the relative position of the electric roller 3 and the guide belt 9, so that the electric roller 3 loses its pressure on the guide belt 9, thereby making the guide belt 9 loose, which facilitates the disassembly and cleaning of the guide belt 9 and improves the efficiency of equipment turnover.

[0027] See Figures 2 to 6The supporting components include: two symmetrically distributed side support plates 4, a support roller 5, a main inner roller 6, a secondary inner roller 7, and a guide 8. The support roller 5 and the main inner roller 6 are both disposed between two connecting seats 12. The support roller 5 and the main inner roller 6 are rotatably connected to the two side support plates 4. The secondary inner roller 7 is disposed on the opposite side of the rear of the two side support plates 4. The secondary inner roller 7 is fixedly connected to the guide 8. The support roller 5, the electric roller shaft 3, the main inner roller 6, and the secondary inner roller 7 are arranged sequentially from front to back. The thickness of the guide 8 gradually decreases from front to back, and it is used to guide the patient to move to the upper side of the guide belt 9. The guide belt 9 is wrapped around the support roller 5 and the guide 8. The connecting seat 12 is used to fix the support roller 5 and the main inner roller 6 on the mounting seat 11 and facilitates disassembly.

[0028] It should be noted that in this embodiment, the arrangement of the support roller 5 and the main inner roller 6 with the connecting seat 12 can be regarded as an insertion connection, so that the support roller 5 and the main inner roller 6 can rotate and slide relative to the connecting seat 12; the arrangement of the connecting seat 12 with the mounting seat 11 can be regarded as a spline connection; the arrangement of the auxiliary inner roller 7 with the side support plate 4 can be regarded as a fixed connection; and the arrangement of the electric slide rail 10 with the bed board 2 can be regarded as a fixed connection.

[0029] The patient transfer procedure is as follows (see attached document). Figure 1 Taking the patient's bed as an example (with the patient's bed located behind the device): the medical staff pushes the device to the patient's bed, then lowers the armrests on the back of the bed board 2, and adjusts the height and position of the bed board 2 until the bed board 2 contacts the front of the bed, and the upper side of the bed board 2 is close to the same height as the upper side of the bed.

[0030] Medical staff activate two electric slide rails 10 and electric rollers 3. The electric slide rails 10 are activated and drive the mounting base 11 and connecting base 12 to move backward through the slider. The two connecting bases 12 together drive the support roller 5 and the main inner roller 6 to move backward. The support roller 5 and the main inner roller 6 drive the side support plate 4, the auxiliary inner roller 7, the guide 8 and the guide belt 9 to move backward together, so that the guide 8 moves between the patient and the bed.

[0031] Electric roller 3 starts and rotates counterclockwise (see appendix). Figure 1 (The left view is for illustration from a rotating perspective). The roller of the electric roller shaft 3 drives the guide belt 9 to rotate through friction. The guide belt 9 drives the support roller 5 to rotate. During this process, the speed at which any point on the guide belt 9 moves is equal to the speed at which the slider on the electric slide rail 10 moves.

[0032] As the guide 8 is inserted between the patient and the bed, the patient moves onto the guide belt 9. Once the patient has completely lost contact with the bed, the electric slide rail 10 stops, and the guide belt 9 continues to move the patient forward until the patient moves between the main inner roller 6 and the auxiliary inner roller 7, at which point the electric roller shaft 3 stops.

[0033] Restart the electric slide rail 10 and move the slider on the electric slide rail 10 forward. The slider on the electric slide rail 10 will move the patient forward through the guide belt 9 until the slider on the electric slide rail 10 is reset, thus completing the transfer operation.

[0034] When it is necessary to move the patient from this device to the bed, repeat the above steps in reverse.

[0035] The procedure for disassembling and cleaning the guide belt 9 is as follows: Pull out the connecting seat 12 on either side (the following explanation will use the connecting seat 12 on the left side as an example), overcome the magnetic attraction between the two magnetic rings 13 and separate the two magnetic rings 13. The connecting seat 12 loses contact with the support roller 5 and the main inner roller 6. At this time, the side support plate 4, support roller 5, main inner roller 6, auxiliary inner roller 7, guide 8 and guide belt 9 can be removed from the bed board 2, so that the guide belt 9 loses contact with the electric roller shaft 3. The guide belt 9 changes from a taut state to a relaxed state. Then, the medical staff will pull the guide belt 9 away from the support roller 5, main inner roller 6, auxiliary inner roller 7 and guide 8 and clean the guide belt 9.

[0036] Example 2

[0037] Based on Example 1, this provides the ability to switch between rigid and flexible support according to the patient's wound location.

[0038] See Figures 2 to 6 , Figure 9 and Figure 10 It also includes: several support mechanisms disposed between the main inner roller 6 and the auxiliary inner roller 7. The support mechanisms are located inside the guide belt 9 and are used to support the guide belt 9 and switch between rigid and flexible support modes. The support mechanisms include: a main mounting cylinder 15, an auxiliary mounting cylinder 16 and a support plate 17. The main mounting cylinder 15 is rotatably connected to the auxiliary inner roller 7, and the auxiliary mounting cylinder 16 is rotatably connected to the main inner roller 6. Both the main mounting cylinder 15 and the auxiliary mounting cylinder 16 are hinged to the support plate 17. The support plate 17 is made of elastic metal and fits against the upper side of the guide belt 9 to provide support for the guide belt 9. The number of support mechanisms is determined according to the width of the guide belt 9 and the support plate 17 in the left and right directions, so that the sum of the widths of all the support plates 17 in the left and right directions is approximately equal to the width of the guide belt 9 in the left and right directions.

[0039] The above settings enable the switching between flexible and rigid support by utilizing the relative positions of the support plate 17 and the guide belt 9, and adjust the position of the corresponding support plate 17 according to the patient's wound location and transport needs. This provides flexible support for the patient's wound, reducing the probability of the wound tearing due to compression, and provides rigid support for the rest of the patient's body, ensuring stability during transport.

[0040] See Figure 4 , Figure 6 , Figure 9 , Figure 11 and Figure 12 A power knob 18 is slidably connected to the left side of the main inner roller 6, and a reset component 19 is fixedly connected to the main inner roller 6. (See also...) Figure 4 The reset member 19 is provided with a receiving groove for accommodating the auxiliary mounting cylinder 16. The reset member 19 is used to control the rotation of the auxiliary mounting cylinder 16. The auxiliary inner roller 7 is rotatably connected to the side support plate 4. (See...) Figure 9 The guide 8 is provided with a receiving groove for accommodating the main mounting cylinder 15, and the guide 8 is used to control the rotation of the main mounting cylinder 15.

[0041] The above settings enable that, after the transfer is completed, the rotation of the reset component 19 and the guide component 8 simultaneously resets all the auxiliary mounting cylinders 16 and all the main mounting cylinders 15, allowing all the support plates 17 to quickly reset and contact the guide belt 9.

[0042] See Figure 5 , Figure 6 and Figures 10 to 13 A main locking member 20 is embedded and slidably connected to the rear side of the main inner roller 6. The left end of the main locking member 20 is fixedly connected to the power knob 18. The main locking member 20 is provided with first protrusions distributed at equal intervals. (See...) Figure 5 and Figure 6 Both the side support plate 4 and the reset member 19 are provided with locking grooves for accommodating the first protrusion on the main locking member 20. (See [link]) Figure 6 and Figure 10 The auxiliary mounting cylinder 16 has two locking grooves, and the central angle corresponding to the projection of the two locking grooves on the end face of the auxiliary mounting cylinder 16 is 120°. Initially, the leftmost first protrusion of the main locking member 20 is located in the locking groove of the side support plate 4, and the remaining first protrusions on the main locking member 20 are located in the corresponding locking grooves of the adjacent auxiliary mounting cylinders 16. The main locking member 20 is used to restrict the rotation of the main inner roller 6, the auxiliary mounting cylinder 16 and the reset member 19 relative to the side support plate 4; the auxiliary inner roller 7 is slidably connected to the auxiliary locking member 21, and the auxiliary locking member 21 is provided with equally spaced second protrusions (see Figure 12 The guide member 8 is provided with a locking groove for accommodating the second protrusion on the secondary locking member 21 (see...). Figure 6 and Figure 10The main mounting cylinder 15 is provided with two locking grooves, and the central angle corresponding to the projection of the two locking grooves on the end face of the main mounting cylinder 15 is 120°. Initially, all the second protrusions on the secondary locking member 21 are located in the corresponding locking grooves of the adjacent main mounting cylinders 15. The secondary locking member 21 is used to restrict the rotation of the secondary inner roller 7, the guide member 8 and the main mounting cylinder 15 relative to the side support plate 4. The left end of the secondary locking member 21 is fixedly connected to the limiting insert plate 14. The rear part of the side support plate 4 is provided with a first limiting groove 141, the left end of the secondary inner roller 7 is provided with a second limiting groove 142, and the left end of the guide member 8 is provided with a third limiting groove 143, which facilitates the traction of the limiting insert plate 14. The limiting insert plate 14 restricts the rotation of the secondary inner roller 7 relative to the side support plate 4 through the first limiting groove 141, the second limiting groove 142 and the third limiting groove 143.

[0043] See Figure 5 , Figure 6 and Figure 10 A support rod 22 is fixedly connected to the lower side of the auxiliary mounting cylinder 16. The support rod 22 is used to support the guide belt 9. Both ends of the support rod 22 are spherical to eliminate the sharp parts of the end face of the support rod 22 and prevent the support rod 22 from scratching the guide belt 9.

[0044] The above settings enable the support rod 22 to support the guide band 9, keeping the guide band 9 taut. When the position of the local support plate 17 is adjusted, the support rod 22 moves together and loses contact with the guide band 9, making the guide band 9 more deformable in the local position, further reducing the support effect of the guide band 9 on the patient's wound and reducing the probability of causing secondary damage to the patient's wound.

[0045] See Figure 6 , Figure 7 and Figure 13 The guide belt 9 has raised edges, meaning that the thickness of the left and right edges of the guide belt 9 is greater than the thickness of the rest of the parts. The left and right sides of the roller, support roller 5, guide 8 and reset part 19 of the electric roller shaft 3 are provided with annular grooves to accommodate the raised edges on the guide belt 9, so as to keep the relative position of the guide belt 9 and the roller, support roller 5, guide 8 and reset part 19 of the electric roller shaft 3 stable.

[0046] See Figure 8 and Figure 13 The mounting base 11 is rotatably connected to the connecting base 12. A support block 23 is fixedly connected to the rear part of the upper side of the electric slide rail 10. The support block 23 contacts the adjacent side support plate 4 and is used to support the adjacent side support plate 4. This allows the entire load-bearing assembly and the guide belt 9 to swing relative to the mounting base 11, which facilitates the swinging of the guide 8 to reset the main mounting cylinder 15.

[0047] When transferring patients, if there is a wound on the contact surface between the patient and the guide belt 9, transferring the patient in this state may easily lead to wound tearing (the following explanation will be based on the patient lying flat with a wound on their back). The measures to deal with this situation are as follows: First, repeat the steps in Embodiment 1 above and move the device next to the bed to be transferred. Then, the medical staff pull the power knob 18 and the limiting plate 14 to the left respectively. The power knob 18 drives the main locking member 20 to move to the left, so that the first protrusion on the leftmost side of the main locking member 20 moves out of the locking groove of the side support plate 4, releasing the main locking member 20 from limiting the main inner roller 6. The remaining first protrusions on the main locking member 20 move out of the locking groove of the adjacent secondary mounting cylinder 16 and enter the locking groove of the reset member 19, releasing the main locking member 20 from limiting the secondary mounting cylinder 16; the limiting plate 14 drives the secondary locking member 21 to move to the left, and the limiting plate 14 moves out of the first limiting groove 141, the second limiting groove 142 and the third limiting groove 143, releasing the limiting plate 14 from limiting the secondary inner roller 7; the second protrusion on the secondary locking member 21 moves out of the locking groove of the adjacent main mounting cylinder 15 and enters the locking groove of the guide member 8, releasing the secondary locking member 21 from limiting the main mounting cylinder 15.

[0048] Medical staff locate the support plate 17 corresponding to the position of the wound on the patient's back and press the found support plate 17 downwards, causing the support plate 17 to bend and store force, which drives the adjacent main mounting cylinder 15 and auxiliary mounting cylinder 16 to rotate. When the hinge point between the main mounting cylinder 15 and auxiliary mounting cylinder 16 and the support plate 17 moves to below the central axis of the main mounting cylinder 15 and auxiliary mounting cylinder 16, the main mounting cylinder 15 and auxiliary mounting cylinder 16 continue to rotate under the elastic action of the support plate 17 until the main mounting cylinder 15 and auxiliary mounting cylinder 16 have rotated 120° respectively. At this point, the support plate 17 returns to its original shape, and the main mounting cylinder 15 and auxiliary mounting cylinder 16 stop rotating.

[0049] During the counterclockwise rotation of the auxiliary mounting cylinder 16, the auxiliary mounting cylinder 16 drives the support rod 22 to rotate. The support rod 22 slides along the inner side of the guide band 9 until the support rod 22 finally loses contact with the guide band 9, thus causing the part of the guide band 9 corresponding to the patient's wound to change from a taut to a relaxed state.

[0050] After the main mounting cylinder 15 and the auxiliary mounting cylinder 16 stop rotating, the medical staff pushes the limiting plate 14 and the power knob 18 to the right, that is, repeats the above steps of pulling the limiting plate 14 and the power knob 18 to the left, so that the main locking member 20 restricts the rotation of all auxiliary mounting cylinders 16, and the limiting plate 14 and the auxiliary locking member 21 jointly restrict the rotation of all main mounting cylinders 15. In this way, the support plate 17 corresponding to the patient's wound loses contact with the guide belt 9, and the guide belt 9 provides flexible support for the patient's wound position, reducing the probability of the patient's wound tearing during the transfer.

[0051] After the patient transfer is completed, the medical staff lifts the support assembly upwards, causing it to swing clockwise around the rotation axis of the connecting seat 12 and the mounting seat 11. This causes the side support plate 4 to lose contact with the adjacent support block 23, thus creating space for the guide 8 to swing. The medical staff then repeats the steps of pulling out the limiting plate 14 and the power knob 18, and then rotates the guide 8 counterclockwise. The guide 8's receiving groove presses against the hinge between the main mounting cylinder 15 and the support plate 17, causing the main mounting cylinder 15 to rotate and drive the adjacent support plates 17 to swing until all the main mounting cylinders 15 are reset. Then, the rotation is clockwise... Rotate the guide 8 to reset it; rotate the power knob 18 clockwise, and the power knob 18 will drive the reset member 19 to rotate through the main locking member 20. The reset member 19 will press the hinge between the auxiliary mounting cylinder 16 and the support plate 17 by the receiving groove, causing the auxiliary mounting cylinder 16 to rotate and drive the adjacent support plate 17 to swing until all the auxiliary mounting cylinders 16 are reset. Then rotate the power knob 18 counterclockwise to reset the power knob 18, the main locking member 20 and the reset member 19. Then repeat the above steps of pushing the limit plate 14 and the power knob 18 to the right to quickly complete the operation of resetting the support plate 17.

[0052] Example 3

[0053] Based on Example 2, the effect of the patient's gravity on the electric slide rail 10 is provided to disperse the force.

[0054] See Figure 13 The rear side of the electric slide rail 10 is rotatably connected to the bed board 2.

[0055] Due to the limitations of medical staff's observation, it is difficult to ensure that the side support plate 4 is completely placed on the side of the bed during the process of protruding from the bed board 2. This means that the patient's weight on the side support plate 4 is entirely supported by the slider of the electric slide rail 10, which can easily lead to the loosening or even damage of the connection between the electric slide rail 10 and its slider.

[0056] The above settings enable the electric slide rail 10 and the bed board 2 to rotate together, allowing the electric slide rail 10 and the side support plate 4 to swing as a whole. The electric slide rail 10 and the bed provide two-point support for the side support plate 4, avoiding the entire weight of the patient being borne by the electric slide rail 10. At the same time, the length of the slider on the electric slide rail 10 is shortened, and the movable distance of the side support plate 4 is extended, making it easier to carry and transport the patient.

[0057] The transfer operation after the above settings is as follows: Repeat the steps of Embodiment 1, move the device to the front of the hospital bed, then adjust the height of the bed board 2 so that the upper side of the bed board 2 is slightly higher than the upper side of the hospital bed. Then, control the load-bearing component and the guide belt 9 to extend together. During the process of the guide 8 moving between the patient and the hospital bed, the patient squeezes the guide 8. At this time, the entire load-bearing component and the electric slide rail 10 form a lever with the rotational position of the electric slide rail 10 and the bed board 2 as the rotation axis. This causes the entire load-bearing component to drive the guide belt 9, electric roller 3, mounting base 11, connecting base 12 and magnetic ring 13 to move, and causes the front side of the electric slide rail 10 to tilt upward. At this time, the rotational position of the electric slide rail 10 and the bed board 2 and the contact position of the guide 8 and the hospital bed provide two-point support, avoiding the patient's weight being entirely borne by the slider of the electric slide rail 10, thus extending the service life of the electric slide rail 10.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention are included within the scope of protection of the present invention.
