Description

Technical Field

[0001] This invention relates to the field of nursing bed technology, and more specifically, to a bed-chair integrated nursing bed and its method of use. Background Technology

[0002] To facilitate patient transfer, existing technology (Chinese Patent, CN213697597U) discloses a nursing bed that combines a bed and a wheelchair into one unit. When the wheelchair is combined with the bed, it can be used as a regular nursing bed. When the wheelchair is separated from the bed, it can be used independently.

[0003] The wheelchair in this type of nursing bed can enter and exit from the left and right sides of the bed. Compared to nursing beds where the wheelchair enters and exits from the rear of the bed, it does not require more space at the rear of the bed and has less restriction on space, thus making it more widely applicable.

[0004] However, in order to allow entry and exit from both sides, this nursing bed has an entrance and exit on one side of the bed that are the same size as a wheelchair. This undoubtedly damages the bed structure and reduces its structural strength. Furthermore, when used as a nursing bed, the patient's body is supported by the wheelchair, and the bed provides less support to the patient's body. This undoubtedly wastes the structural performance of the bed and may bring the risk of tipping over. In addition, because the size of the entrance and exit needs to be adapted to the size of the wheelchair, the wheelchair often cannot be placed in the middle of the bed when used as a nursing bed. This means that the patient still needs to move their body during actual use, which obviously causes great inconvenience to the patient.

[0005] There is currently no effective technical solution to the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a bed-chair integrated nursing bed and its usage method. The smaller entrance and exit are conducive to improving the structural strength of the bed and do not hinder the wheelchair from entering the middle of the bed. The patient does not need to move his body, reducing inconvenience. At the same time, the bed structure supports the wheelchair, so that the patient's body is supported by the bed, effectively reducing the risk of tipping over.

[0007] In a first aspect, the present invention provides a bed-chair integrated nursing bed, comprising: The bed frame has an inlet / outlet on one side in the left-right direction, a first support part is provided on the front side of the inlet / outlet, and a second support part is provided on the rear side of the inlet / outlet. The wheelchair includes a seat and a swingable first and second movable parts. The seat supports the buttocks, the first movable part is located at the front of the seat and supports the back, and the second movable part is located at the rear of the seat and supports the legs. The first and second movable parts swing upwards to a first preset angle and can move with the wheelchair over the bed, allowing the wheelchair to enter and exit the bed through the inlet / outlet. After entering the bed, the wheelchair is positioned in the middle of the bed's left-right direction. When the first movable part swings to a horizontal position, it is supported by the first support part, and when the second movable part swings to a horizontal position, it is supported by the second support part.

[0008] The integrated bed and chair nursing bed provided by the present invention improves the structural strength of the bed frame without hindering the entry and exit of the wheelchair by reducing the size of the entrance and exit, and allows the wheelchair to be placed in the middle of the bed frame, so that the bed frame can effectively play a supporting role, while avoiding inconvenience to the patient.

[0009] Furthermore, the bottom of the bed is provided with a first telescopic mechanism and two second telescopic mechanisms, which are arranged in a triangular pattern. Both the first telescopic mechanism and the second telescopic mechanism are capable of extending and retracting in the vertical direction and are used to cooperate with each other to drive the bed to rise and fall in the vertical direction.

[0010] The adjustable bed height makes it easier for medical staff to care for patients and accommodate the different height requirements of various patients, which helps to reduce the psychological burden on patients.

[0011] Furthermore, multiple first pin holes are provided on both the front and rear sides of the inlet and outlet; multiple first pins are provided on both the front and rear sides of the bottom of the wheelchair; after the wheelchair enters the bed, each first pin is aligned with a corresponding first pin hole in the vertical direction, and as the bed rises, the first pin is inserted into the first pin hole to fix the wheelchair to the bed.

[0012] The first pin is inserted into the first pin hole in conjunction with the bed frame lifting mechanism, thereby strengthening the fixation between the wheelchair and the bed frame and ensuring that the wheelchair is locked onto the bed frame.

[0013] Furthermore, the telescopic end of the first telescopic mechanism is rotatably connected to the bed body; The telescopic end of the second telescopic mechanism is rotatably connected to a first slider, and the first slider is slidably connected to the bed body; The first telescopic mechanism and the second telescopic mechanism are also used to cooperate with each other to drive the bed to flip to the left or right.

[0014] Adjusting the patient's posture by moving the bed can reduce the difficulty of turning the patient over, making it easier for medical staff to care for the patient.

[0015] Furthermore, a third support portion is provided on both the left and right sides of the inlet and outlet; a swingable third movable portion is provided on both the left and right sides of the seat cushion portion, the third movable portion being used to support the human hand and being able to swing to a horizontal state; after the wheelchair enters the bed and the third movable portion swings to a horizontal state, the third movable portion is supported by the third support portion.

[0016] Furthermore, the wheelchair also includes a first mattress that covers the upper surfaces of the seat, the first movable part, and the second movable part.

[0017] Furthermore, the first mattress can be folded from the position corresponding to the connection between the seat cushion and the second movable part, and can also be folded from the position corresponding to the connection between the seat cushion and the first movable part.

[0018] Furthermore, the first movable part is slidably provided with at least one second slider, which is capable of reciprocating in a direction close to or away from the cushion part; all the second sliders are connected to the first mattress and are used to drive the first mattress to move.

[0019] Furthermore, the bed frame includes a second mattress, which is disposed around the first support portion and the second support portion and forms a first recessed space; After the wheelchair enters the bed, and the first movable part swings to the horizontal, the left and right sides of the first movable part are surrounded by the second mattress, and when the second movable part swings to the horizontal, the left and right sides of the second movable part are surrounded by the second mattress.

[0020] Furthermore, both the first support portion and the second support portion are recessed relative to the top of the bed body to form a second recessed space; After the wheelchair enters the bed, and the first movable part swings to the horizontal, the first movable part is embedded in the second recessed space corresponding to the first support part, and when the second movable part swings to the horizontal, the second movable part is embedded in the second recessed space corresponding to the second support part.

[0021] Furthermore, the first supporting part is provided with a load-bearing beam, which is used to support the first movable part after the first movable part swings to a horizontal position.

[0022] Furthermore, the second movable part is provided with second pins on both sides in the left and right directions, and the second support part is provided with second pin holes on both sides in the left and right directions. The second pins can be inserted into the second pin holes on the same side to fix the second movable part and the second support part together.

[0023] Furthermore, the wheelchair is equipped with swivel wheels and all-way wheels.

[0024] Furthermore, the wheelchair is provided with two omnidirectional wheels on the side closer to the first movable part, and two universal wheels on the side closer to the second movable part.

[0025] Secondly, the present invention provides a method of use for the aforementioned integrated bed-chair nursing bed, comprising the following steps: S1. When the wheelchair enters the bed, the following steps are performed: S11. Control the first and second movable parts to swing upwards to a first preset angle; S12. Control the wheelchair to move to the middle position in the left-right direction of the bed through the inlet and outlet; S13. Control the first and second movable parts to swing downwards to a horizontal position; S2. When the wheelchair leaves the bed, the following steps are performed: S21. Control the first and second movable parts to swing upwards to the first preset angle; S22. Control the wheelchair to leave the bed body from the middle position in the left-right direction through the inlet and outlet; S23. Control the second movable part to swing downwards to a third preset angle.

[0026] As can be seen from the above, the integrated bed and chair nursing bed provided by the present invention has the following advantages: Firstly, by utilizing the movable first and second support parts of the wheelchair itself to swing to a certain angle, the area occupied by the wheelchair when entering and exiting can be reduced. This allows for wheelchair entry and exit with a smaller entrance and exit on the bed, avoiding the reduction of the bed's structural strength by a larger entrance and exit. Secondly, the bed is equipped with a first support and a second support for the wheelchair, so that the patient's body weight is concentrated on the bed, which allows the bed to effectively play its supporting role and reduce the risk of tipping over. Third, the wheelchair can be moved directly to the center of the bed, and after being flattened, the patient can sit directly in the center of the bed without having to move their body again, making the whole system more humane.

[0027] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing embodiments of the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0052] Reference Appendix Figure 1 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 and attached Figure 14 This invention provides a bed-chair integrated nursing bed, comprising: The bed body 100 has an inlet and outlet 110 on one side in the left and right directions, a first support part 120 is provided on the front side of the inlet and outlet 110, and a second support part 130 is provided on the rear side of the inlet and outlet 110. Wheelchair 200 includes a seat 210 and a pivotable first movable part 220 and a second movable part 230 (the second movable part 230 may include a lower leg section and a footrest section; the lower leg section is rotatably connected to the seat 210, and the lower leg section and the footrest section are rotatably connected. When used as a wheelchair, the lower leg section serves as a backrest for the lower legs, and the footrest section supports the feet, thus constituting the basic elements of a wheelchair). The seat 210 supports the buttocks, the first movable part 220 is located in front of the seat 210 and supports the back, and the second movable part 230 is located in front of the seat 210. The rear side of 210 is used to support the legs of the human body; after the first movable part 220 and the second movable part 230 swing upward to the first preset angle, they can move with the wheelchair 200 and pass over the bed 100 so that the wheelchair 200 can enter and exit the bed 100 through the inlet and outlet 110; after the wheelchair 200 enters the bed 100, the wheelchair 200 is in the middle position in the left and right direction of the bed 100, and when the first movable part 220 swings to the horizontal, the first movable part 220 is supported by the first support part 120, and when the second movable part 230 swings to the horizontal, the second movable part 230 is supported by the second support part 130.

[0053] In this embodiment, the inlet and outlet 110 are located on the left and right sides of the bed 100, which reduces space restrictions and facilitates the entry and exit of the wheelchair 200. In practical applications, unlike existing wheelchair-integrated nursing beds, the width of the inlet and outlet 110 of the bed 100 in this embodiment is much smaller than the length of the wheelchair 200 after it is flattened (greater than or equal to the length of the seat cushion 210). Therefore, the first movable part 220 and the second movable part 230 are set to be swingable. When the wheelchair 200 needs to be assembled or disassembled, the first movable part 220 and the second movable part 230 only need to be swung upward to a certain angle. This avoids interference between the first movable part 220 and the second movable part 230 and the structure of the bed 100 when the wheelchair 200 moves laterally, so that the seat cushion 210 can pass smoothly through the inlet and outlet 110 to finally realize the entry and exit of the wheelchair 200. By reducing the size of the inlet and outlet 110, the structural strength of the bed 100 is improved.

[0054] It should be noted that, taking the installation of wheelchair 200 into bed 100 as an example, the patient sits normally in wheelchair 200, adjusts the angle of the first movable part 220 and then leans against the first movable part 220. After that, the second movable part 230 is adjusted to swing upward to a certain angle. Since the second movable part 230 is used to support the patient's legs, the patient's legs can swing upward to a certain angle on their own. Therefore, the upward swing of the legs supported by the second movable part 230 will not cause discomfort to the patient. Thus, the process of wheelchair 200 entering and leaving bed 100 does not require the patient to leave wheelchair 200, thereby avoiding inconvenience and stress to the patient and is more in line with medical care concepts.

[0055] Furthermore, the wheelchair 200 can be inserted into the middle of the left and right sides of the bed 100 through the inlet and outlet 110. After the wheelchair 200 is flattened, the patient will be directly in the center of the bed 100 without having to move his body (to ensure the patient's safety and to provide space for the patient to turn over on both sides, the experience of the body being in the center of the bed 100 is the best), which further facilitates the use of the patient and avoids inconvenience and stress to the patient.

[0056] Furthermore, after the wheelchair 200 is unfolded, the patient's body weight can be roughly divided into three parts: the heavier torso and hips, and the lighter legs. The first support part 120 is mainly used to support the weight of the torso, the wheelchair 200 itself (i.e., the seat 210) is mainly used to support the weight of the hips, and the second support part 130 is mainly used to support the weight of the legs. This allows the bed 100 and the wheelchair 200 to share the patient's body weight, avoiding the waste of the bed 100's performance by having the weight concentrated on the wheelchair 200, and is more conducive to reducing the risk of tipping over.

[0057] In some embodiments, reference is made to the appendix. Figure 5 and attached Figure 6The bottom of the bed body 100 is provided with a first telescopic mechanism 140 and two second telescopic mechanisms 150, which are arranged in a triangular pattern. The first telescopic mechanism 140 and the second telescopic mechanism 150 can both extend and retract in the vertical direction and are used to cooperate with each other to drive the bed 100 to rise and fall in the vertical direction.

[0058] In this embodiment, a first telescopic mechanism 140 and a second telescopic mechanism 150 are provided to realize the lifting function of the bed 100. For medical staff, adjusting the height of the bed 100 allows them to care for patients in a more convenient posture and with smoother operation, which can reduce the fatigue of medical staff. For patients, on the one hand, they can receive better nursing services, and on the other hand, it can cater to the different patients' preferences for the height of the bed 100, which helps to reduce the psychological burden of patients.

[0059] Furthermore, the triangular arrangement of one first telescopic mechanism 140 and two second telescopic mechanisms 150 ensures the overall stability of the bed 100 during lifting and lowering, which helps reduce the risk of tipping over.

[0060] In some embodiments, reference is made to the appendix. Figure 7 Appendix Figure 8 Appendix Figure 11 and attached Figure 12 Multiple first pin holes 160 are provided on both the front and rear sides of the inlet and outlet 110; multiple first pins 240 are provided on both the front and rear sides of the bottom of the wheelchair 200; after the wheelchair 200 enters the bed 100, each first pin 240 is aligned with a corresponding first pin hole 160 in the vertical direction, and as the bed 100 rises, the first pin 240 is inserted into the first pin hole 160 to fix the wheelchair 200 to the bed 100.

[0061] In this embodiment, the first pin 240 is inserted into the first pin hole 160 in conjunction with the lifting and lowering of the bed 100, thereby strengthening the fixation strength between the wheelchair 200 and the bed 100, which is more in line with the concept of integrated design. At the same time, as long as the bed 100 does not descend to the preset height, it can ensure that the wheelchair 200 is locked on the bed 100. In addition, after the bed 100 rises to the preset height, the bed 100 can lift the entire wheelchair 200, thereby distributing the weight borne by the wheelchair 200 to the bed 100 with higher structural strength. It is equivalent to the bed 100 bearing the entire weight of the patient's body, relieving the pressure on the bottom rollers of the wheelchair 200, thereby avoiding damage to the rollers due to long-term pressure, and helping to extend the overall service life of the wheelchair 200.

[0062] In some embodiments, reference is made to the appendix. Figure 5 and attached Figure 6 The telescopic end of the first telescopic mechanism 140 is rotatably connected to the bed 100; The telescopic end of the second telescopic mechanism 150 is rotatably connected to the first slider 151, and the first slider 151 is slidably connected to the bed 100. The first telescopic mechanism 140 and the second telescopic mechanism 150 are also used to cooperate with each other to drive the bed 100 to flip to the left or right.

[0063] In practical applications, some nursing procedures may require patients to turn over, such as for injections, back rubs, and medication application. However, some patients may have difficulty turning over on their own due to physical reasons, requiring assistance from medical staff. Since the patient's body has a certain weight, medical staff may find it difficult to push the patient or may cause discomfort if the push is too forceful. In this embodiment, after ensuring that the wheelchair 200 is completely fixed to the bed 100, the extension and retraction of the first telescopic mechanism 140 and the second telescopic mechanism 150 can be controlled separately to enable the bed 100 to achieve a side-turning function. The bed 100 can then move the patient's body to adjust the patient's posture, which can reduce the difficulty of turning the patient over to a certain extent, making it easier for medical staff to care for the patient.

[0064] In some embodiments, reference is made to the appendix. Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 8 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 and attached Figure 14 The left and right sides of the inlet and outlet 110 are provided with a third support part 170; the left and right sides of the seat cushion 210 are provided with a swingable third movable part 250, which is used to support the human hand and can swing to a horizontal state; after the wheelchair 200 enters the bed 100, and when the third movable part 250 swings to a horizontal state, the third movable part 250 is supported by the third support part 170.

[0065] In this embodiment, when the wheelchair 200 is used as a wheelchair after being separated from the bed 100, the third support part 170 is controlled to swing to an upright state to act as an armrest to support the weight of the user's hands; when the wheelchair is used as a bed after being combined with the bed 100, the third support part 170 can be flattened and become part of the bed, or it can be swinged to an upright state to act as a guardrail to block the patient's body and prevent the patient from overturning or from slipping on the bed 100 due to its tilt, thus preventing the patient from falling off the bed 100.

[0066] In some embodiments, reference is made to the appendix. Figure 9 and attached Figure 10The wheelchair 200 also includes a first mattress 260, which covers the upper surfaces of the seat 210, the first movable part 220, and the second movable part 230. The first mattress isolates the rigid structure of the wheelchair 200 and acts as a cushion to the human body, thereby improving the patient's comfort.

[0067] In some embodiments, reference is made to the appendix. Figure 9 and attached Figure 10 The first mattress 260 can be folded from the position corresponding to the connection between the seat cushion 210 and the second movable part 230, and can also be folded from the position corresponding to the connection between the seat cushion 210 and the first movable part 220. The foldable first mattress 260 can adapt to the swinging movements of the first movable part 220 and the second movable part 230, thereby preventing the first mattress 260 from falling off the wheelchair 200.

[0068] In some embodiments, reference is made to the appendix. Figure 10 Appendix Figure 11 and attached Figure 14 The first movable part 220 is slidably provided with at least one second slider 221, which can reciprocate in the direction of approaching or moving away from the cushion part 210; all second sliders 221 are connected to the first mattress 260 and are used to drive the first mattress 260 to move.

[0069] In this embodiment, the second slider 221 is set to move the first mattress 260 to avoid the structure between the first mattress 260 being squeezed when the first movable part 220 and the second movable part 230 swing, so that the first mattress 260 can better cover the upper surface of the cushion part 210, the first movable part 220 and the second movable part 230.

[0070] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and attached Figure 8 The bed frame 100 includes a second mattress 180, which is arranged around the first support portion 120 and the second support portion 130 to form a first recessed space (the two first recessed spaces are respectively used for the front and rear ends of the first mattress 260 to be inserted). After the wheelchair 200 enters the bed 100, and the first movable part 220 swings to the horizontal, the left and right sides of the first movable part 220 are surrounded by the second mattress 180, and when the second movable part 230 swings to the horizontal, the left and right sides of the second movable part 230 are surrounded by the second mattress 180.

[0071] In this embodiment, after the wheelchair 200 is flattened in the bed 100, it will be blocked by the second mattress 180, thereby further limiting the left and right directions of the wheelchair 200 and ensuring that the wheelchair 200 and the bed 100 form a complete unit.

[0072] Furthermore, a second mattress 180 of appropriate thickness is selected so that the upper surface of the second mattress 180 is flush with the upper surface of the first mattress 260, thereby making the surface of the bed 100 flat and avoiding the formation of a step at the junction of the first mattress 260 and the second mattress 180, which would cause discomfort to the patient.

[0073] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 and attached Figure 8 The first support portion 120 and the second support portion 130 are both recessed relative to the top of the bed body 100 to form a second recessed space; After the wheelchair 200 enters the bed 100, and the first movable part 220 swings to the horizontal, the first movable part 220 is embedded in the second recessed space corresponding to the first support part 120, and when the second movable part 230 swings to the horizontal, the second movable part 230 is embedded in the second recessed space corresponding to the second support part 130.

[0074] In this embodiment, after the wheelchair 200 is flattened in the bed 100, it will be blocked by the first support part 120 and the second support part 130, thereby further limiting the left and right directions of the wheelchair 200 and ensuring that the wheelchair 200 and the bed 100 form a complete unit.

[0075] Furthermore, a second mattress 180 of appropriate thickness is selected and placed around the first mattress 260 on the bed frame 100, with the upper surface of the second mattress 180 flush with the upper surface of the first mattress 260, thereby making the surface of the bed frame 100 flat and avoiding the formation of a step at the junction of the first mattress 260 and the second mattress 180, which would cause discomfort to the patient.

[0076] In some embodiments, reference is made to the appendix. Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 and attached Figure 8 The first supporting part 120 is provided with a load-bearing beam 121, which is used to support the first movable part 220 after the first movable part 220 swings to the horizontal.

[0077] Since the human body weight is mainly concentrated in the upper body (i.e. above the buttocks, including the buttocks), and the buttocks are supported by the wheelchair 200, in order to make the bed 100 have better strength to support the human torso, this embodiment improves the load-bearing capacity of the first support part 120 by setting a thicker load-bearing beam 121, which is beneficial to improving the overall reliability and safety of the integrated bed and chair nursing bed.

[0078] In some embodiments, the second support portion 130 may also be provided with a load-bearing beam for supporting the second movable portion 230 after the second movable portion 230 swings to a horizontal position.

[0079] In some preferred embodiments, refer to the appendix Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 Appendix Figure 7 Appendix Figure 9 Appendix Figure 10 Appendix Figure 11 Appendix Figure 13 and attached Figure 14 The second movable part 230 is provided with a second pin 231 on both sides in the left and right directions, and the second support part 130 is provided with a second pin hole 131 on both sides in the left and right directions. The second pin 231 can be inserted into the second pin hole 131 located on the same side so that the second movable part 230 and the second support part 130 are fixedly connected.

[0080] Compared to setting a load-bearing beam in the second support portion 130 to prevent the second movable portion 230 from swinging downwards, this embodiment uses a pin hole connection method. When the second pin 231 is inserted into the second pin hole 131, the second movable portion 230 can be locked onto the second support portion 130, which also improves the load-bearing capacity of the second support portion 130. Since the weight of the lower body (i.e., the leg area) is relatively light, it is sufficient to ensure that the second support portion 130 can support the weight of the lower body. (See attached figure) Figure 2 Considering that a commode can be installed directly below the seat cushion 210 so that the patient can defecate while sitting in the wheelchair 200, the second movable part 230 can swing downward after the second pin 231 is pulled out from the second pin hole 131, so that the patient can defecate normally while sitting in the wheelchair 200.

[0081] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 9 Appendix Figure 10 and attached Figure 11 The wheelchair 200 is equipped with casters 270 and omnidirectional wheels 280.

[0082] The swivel casters 270 guide the movement of the wheelchair 200, enabling it to move forward, backward, and turn like a regular wheelchair. The omnidirectional casters 280 allow the wheelchair 200 to move laterally in a straight line, allowing it to pass through the inlet / outlet 110 into and out of the bed 100 more smoothly, thus reducing the difficulty of assembling and disassembling the wheelchair 200 and the bed 100.

[0083] In some embodiments, reference is made to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 3 Appendix Figure 9 Appendix Figure 10 and attached Figure 11 The wheelchair 200 has two omnidirectional wheels 280 on the side near the first movable part 220 and two universal wheels 270 on the side near the second movable part 230.

[0084] In this embodiment, the two omnidirectional wheels 280 and the two universal wheels 270 form a four-legged structure, which can ensure the stability of the wheelchair 200 when it moves, and when used together, the wheelchair 200 moves more flexibly.

[0085] Reference Appendix Figure 15 The present invention also provides a method of use for the bed-chair integrated nursing bed in the above embodiments, comprising the following steps: S1. When the wheelchair is placed into the bed, perform the following steps: S11. Control the first and second movable parts to swing upwards to a first preset angle; S12. Control the wheelchair to move to the middle position in the left-right direction of the bed through the entrance and exit; S13. Control the first and second movable parts to swing downwards to a horizontal position; S2. When the wheelchair is removed from the bed, perform the following steps: S21. Control the first and second movable parts to swing upwards to a first preset angle; S22. Control the wheelchair to leave the bed body from the middle position in the left and right directions through the entrance and exit; S23. Control the first movable part to swing upward to the second preset angle (not to continue swinging to the second preset angle based on the first preset angle, but to swing directly to the second preset angle with the first movable part in a horizontal state as the 0° reference; the purpose of swinging to the second preset angle is to make the first movable part function as a normal wheelchair backrest. If the entrance and exit are designed properly, the second preset angle can be the same as the first preset angle, so that the first movable part can no longer be controlled to swing when the wheelchair enters or exits the bed) and control the second movable part to swing downward to the third preset angle (lower the patient's legs to make the patient in a normal sitting position).

[0086] Traditional integrated bed-chair nursing beds allow wheelchairs to be easily moved in and out of the bed by simply flattening them. However, unlike existing technologies, this embodiment reduces the width of the entrance / exit to improve the bed's structural strength. Therefore, the wheelchair cannot enter or exit the bed through the entrance / exit when flattened. Instead, the first and second movable parts must be controlled to swing upwards to a certain angle to prevent interference with the bed structure, allowing the seat cushion to pass smoothly through the entrance / exit. This process utilizes the swinging function of the first and second movable parts and adapts to the joint movements of the patient's legs. While ensuring that the upward swinging of the first and second movable parts does not cause discomfort to the patient, it opens up more optimization space for the bed structure, thereby improving the bed's structural strength, centering the wheelchair, and fully utilizing the bed's support function.

[0087] It should be noted that if the wheelchair has a first pin at the bottom and a first pin hole at the inlet / outlet, then before step S11, the bed is lowered to a position below the preset height, so that the first pin smoothly enters the inlet / outlet with the wheelchair and aligns with the first pin hole in the vertical direction; similarly, after step S13, the bed is raised to the preset height, so that the first pin is inserted into the first pin hole to ensure that the wheelchair is fixedly connected to the bed; similarly, before step S21, the bed is lowered to a position below the preset height, so that the first pin is pulled out from the first pin hole and smoothly leaves the inlet / outlet with the wheelchair; similarly, after step S23, the bed is raised to the preset height, so that the bed returns to its initial state.

[0088] In some embodiments, reference is made to the appendix. Figure 2 When the wheelchair is assembled into the bed and needs to be switched to a sitting position, the second pin is pulled out from the second pin hole, and then the second movable part is swung downward to a certain angle, while the first movable part is swung upward to a certain angle. At this time, the patient can perform behaviors such as eating and defecating in a normal sitting posture.
