Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a movable nursing bed. Background Technology

[0002] As the name suggests, a nursing bed is a bed designed for patients or the elderly, serving to assist in their care and simplify post-care. Nursing beds are currently widely used in hospitals, nursing homes, and other similar facilities. However, with societal progress, technological advancements, and an aging population, the market applications and prospects for nursing beds are expanding, attracting increasing attention and importance.

[0003] Existing nursing beds have limited functionality, only able to lift the user's back during use. Therefore, for patients with limited mobility, prolonged periods of lying flat can easily lead to bedsores and other conditions, and may cause functional decline. Furthermore, medical studies indicate that maintaining the same posture without effective exercise can disrupt bodily functions, causing stiffness and numbness in the affected area. Therefore, further improvements are warranted. Summary of the Invention

[0004] In order to assist patients in moving their lower body and prevent stiffness and numbness caused by prolonged lying down, and to reduce the occurrence of bedsores and other conditions, this application provides a movable nursing bed.

[0005] The movable nursing bed provided in this application adopts the following technical solution:

[0006] A movable nursing bed includes a bed frame; a backrest mechanism mounted on the bed frame for supporting the patient's back during use; and a leg flexion mechanism mounted on the bed frame for assisting the patient in leg flexion activities during use.

[0007] By adopting the above technical solutions, in actual use, the back-raising mechanism can selectively support the patient's back to assist the patient in getting up, making it easier for subsequent caregivers to assist the patient with eating, drinking, and other needs, while also assisting the patient in moving their upper body. The leg-bending mechanism assists the patient in bending their legs to help them move their lower body, preventing stiffness and numbness caused by prolonged lying down, and reducing the occurrence of bedsores and other conditions.

[0008] Optionally, the bed frame includes a headboard, a footboard, and a bed frame installed between the headboard and the footboard. The backrest lifting mechanism and the leg bending mechanism are both installed on the bed frame. Rollers are installed on both sides of the bottom of the headboard and the bottom of the footboard. The headboard and the footboard can be adjusted in height by a lifting drive to lift the head section or the foot section of the bed frame at the corresponding position.

[0009] By adopting the above technical solutions, the first mode involves both the headboard and footboard rising, which is the normal nursing bed posture and enables normal nursing bed functions. The second mode involves both the headboard and footboard lowering, creating a head-lower, tail-lower position, allowing nursing staff to more easily approach the patient for nursing and monitoring. The third mode involves the headboard rising and the footboard lowering, creating a head-higher, tail-lower position, facilitating nursing staff to assist patients with getting up, transferring them, and other nursing tasks. The fourth mode involves the headboard lowering and the footboard rising, creating a head-lower, tail-higher position to suit special nursing needs. For example, for some patients with lower limb paralysis, this posture can promote fluid circulation and drainage, reducing lower limb edema.

[0010] Optionally, the headboard and footboard each include a bottom connecting part, a top connecting part, and a telescopic rod installed between the bottom connecting part and the top connecting part. The telescopic rod is set downwards and is shaped as smaller at the bottom and larger at the top. The two ends of the bed are respectively connected to the upper part of the corresponding telescopic rod.

[0011] Optionally, the lifting drive component is an electric push rod, which is arranged parallel to the telescopic rod, with the bottom of the electric push rod hinged to the bottom connecting part and the top of the electric push rod connected to the top connecting part.

[0012] By adopting the above technical solution, when the electric push rod extends, it lifts the corresponding headboard or footboard to raise the head or foot section of the bed. Simultaneously, since both ends of the electric push rod are hinged, it can be adapted for different configurations, allowing for some flexibility to improve the overall adjustability of the headboard or footboard.

[0013] Optionally, the backrest lifting mechanism includes a backrest plate and a backrest lifting drive. The backrest plate is installed on the side of the bed frame near the headboard, and the inward end of the backrest plate is rotatably connected to the bed frame. The backrest lifting drive is installed between the bed frame and the backrest plate and is used to control the backrest plate to swing up or swing down.

[0014] By adopting the above technical solution, nursing staff can choose to raise the back support board by controlling the back lifting drive to lift the patient's back, so as to carry out subsequent nursing work such as eating, drinking, and cleaning.

[0015] Optionally, the leg-bending mechanism includes a thigh support, a calf support, and a leg-bending drive component; the thigh support and calf support are arranged on the side of the bed frame near the footrest, with the thigh support positioned inward and the calf support positioned outward; the ends of the thigh support and calf support close to each other are rotatably connected, and the ends of the thigh support away from the calf support are rotatably connected to the bed frame; the leg-bending drive component is installed between the bed frame and the thigh support and is used to control the thigh support to swing up or swing down.

[0016] By adopting the above technical solution, nursing staff can choose to raise the thigh support by controlling the leg flexion drive during nursing work, so that the thigh support and the calf support form a "︿" shape, which helps the patient to perform leg flexion activities, helps the patient's lower limb movement, promotes blood circulation, makes the lower limb less prone to stiffness, and is conducive to the patient's recovery.

[0017] Optionally, a leg-lifting support rod is installed between the bed and the leg support plate. The leg-lifting support rod includes a rod body and a rod sleeve. The rod body is slidably and telescopically inserted into the rod sleeve. The tail of the rod sleeve is hinged to the bed, and the head of the rod body is hinged to the bottom of the leg-lifting support rod. A guide groove is provided inside the rod sleeve, and the guide groove extends along the length of the rod sleeve. A locking port is provided inside the guide groove, and the locking ports are arranged at intervals along the length of the guide groove. A locking element and a switching element are installed at the tail of the rod body. When the leg support plate is lifted, the switching element releases the locking element, and the locking element moves along the guide groove and falls into any locking port. After the outward pulling stops, it locks in the locking port. When the leg support plate is lowered, the switching element locks the locking element, and the locking element moves along the guide groove to reset.

[0018] Optionally, the locking component includes a swing hook, a locking pin, and a locking spring. The swing hook is oscillatingly mounted on the rod body, and the locking pin is mounted on the swing hook and swings with it. The locking spring is used to press the swing hook to swing towards the locking port. A movable limiting port is formed between the tail of the rod body and the rod sleeve. The switch component is slidably mounted in the movable limiting port and moves in the same direction as the rod body. The switch component has a locking port and a movable port. The locking port and the movable port are connected. When the switch component moves towards the tail of the rod body, the locking pin slides out from the locking port into the movable port to unlock. When the switch component moves in the other direction, the locking pin slides in from the movable port into the locking port to lock.

[0019] By adopting the above technical solution, when the calf support is lifted, the rod extends, and the switch moves to the left relative to the rod. The locking pin slides out from the locked slot into the movable slot to unlock. At this time, the locking pin moves along the guide groove and can fall into any locking slot. After the pull stops, it locks in the corresponding locking slot to complete the lifting of the calf support again, assisting the patient in lifting their leg. When it is necessary to lower the calf support, the rod is first pulled outward to its limit position. At this time, the locking pin falls back to the right end position in the guide groove. Then, the calf support is lowered, and the rod retracts. At this time, the switch moves away from the tail of the rod relative to the rod, and the locking pin slides from the movable slot into the locked slot to lock. At this time, the locking pin cannot move or swing, but can only move and reset along the guide groove until it returns to the bent leg position. This is to wait for the subsequent return to the bent leg position. The leg bending drive controls the thigh support and calf support to return to the initial flat position.

[0020] Optionally, the bed frame and headboard, and the bed frame and footboard are detachably connected by connectors. Each connector includes a first connecting part and a second connecting part. The first connecting part is used to connect to the bed frame, and the second connecting part is used to connect to the corresponding headboard or footboard. A connecting cylinder is fixedly installed on the bed frame. The first connecting part and the connecting cylinder are connected by a horizontal interlocking method and are detachably locked by a locking device.

[0021] By adopting the above technical solution, since the first connecting part and the connecting cylinder are connected by horizontal insertion, a horizontally combined detachable connection is formed between the first connecting part and the bed. This allows workers to detach the connection between the bed and the corresponding headboard and footboard by horizontal pulling during disassembly, facilitating disassembly and assembly.

[0022] Optionally, a sound-absorbing pad may also be installed at the connection point between the connecting cylinder and the first connecting part.

[0023] By adopting the above technical solution, the location is made quieter, making it less likely to generate harsh noise, thereby improving the user experience.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. In actual use, the back support mechanism can selectively support the patient's back to assist them in getting up, making it easier for caregivers to help them with eating, drinking, and other needs. It can also help patients move their upper body. The leg flexion mechanism can assist patients in bending their legs to help them move their lower body, preventing stiffness and numbness caused by prolonged lying down, and reducing the occurrence of bedsores and other conditions.

[0026] 2. Mode 1: Both the headboard and footboard are raised, representing the normal nursing bed posture and enabling normal nursing bed functions. Mode 2: Both the headboard and footboard are lowered, creating a head-down, tail-down position, allowing nursing staff to more easily access the patient for care and monitoring. Mode 3: The headboard is raised and the footboard is lowered, creating a head-up, tail-down position, facilitating assistance with patient getting up, transfers, and other nursing tasks. Mode 4: The headboard is lowered and the footboard is raised, creating a head-down, tail-up position, suitable for special nursing needs. For example, for patients with lower limb paralysis, this posture can promote fluid circulation and drainage, reducing lower limb edema.

[0027] 3. When performing nursing care, nurses can choose to raise the thigh support by controlling the leg flexion drive, so that the thigh support and the calf support form a "︿" shape, which helps the patient to perform leg flexion activities, helps the patient's lower limb movement, promotes blood circulation, makes the lower limb less prone to stiffness, and is conducive to the patient's recovery.

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-11 This application will be described in further detail.

[0042] This application discloses a movable nursing bed.

[0043] Reference Figure 1 A movable nursing bed includes a bed frame 1, a backrest lifting mechanism 2, and a leg bending mechanism 3. The bed frame 1 includes a headboard 11, a footboard 12, and a bed body 13 installed between the headboard 11 and the footboard 12. The backrest lifting mechanism 2 and the leg bending mechanism 3 are both installed on the bed body 13. The backrest lifting mechanism 2 is located on the side of the bed body 13 near the headboard 11 and is used to support the patient's back during use. The leg bending mechanism 3 is located on the side of the bed body 13 near the footboard 12 and is used to assist the patient in bending their legs during use.

[0044] In practical use, the back support mechanism 2 can selectively support the patient's back to assist the patient in getting up, making it easier for subsequent caregivers to assist the patient with eating, drinking, and other needs. It can also help the patient move their upper body. The leg bending mechanism 3 can assist the patient in bending their legs to help them move their lower body, preventing stiffness and numbness caused by maintaining a supine position for a long time, and reducing the occurrence of bedsores and other conditions.

[0045] Specifically, both the headboard 11 and the footboard 12 include a bottom connecting part 41, a top connecting part 42, and a telescopic rod 43 installed between the bottom connecting part 41 and the top connecting part 42. There are two telescopic rods 43, arranged at intervals, with the bottom rods 43 facing downwards and wider at the top. Two rollers 44 are installed at the bottom of the bottom connecting part 41, and these rollers 44 are lockable. The two ends of the bed frame 13 are respectively connected to the upper parts of the telescopic rods 43 installed in the corresponding headboard 11 and footboard 12. Both the headboard 11 and footboard 12 are adjusted for height via a lifting drive 45, thereby raising the head or foot of the bed frame 13 at the corresponding positions.

[0046] In this embodiment, the lifting drive 45 is an electric push rod, which is arranged parallel to the telescopic rod 43. The bottom of the electric push rod is hinged to the bottom connecting part 41, and the top of the electric push rod is connected to the top connecting part 42. At the same time, the bottom of the headboard 11 and the footboard 12 are both equipped with rollers 44. During the operation of the lifting drive 45, the headboard 11, the footboard 12, the bed 13 and the ground form a parallelogram structure, which can better complete the conversion of the nursing bed posture.

[0047] In actual use, the nursing bed can be used in four different modes by using the lifting drive 45 in the headboard 11 and footboard 12.

[0048] In the first mode, both the headboard 11 and the footboard 12 are raised, which is the normal nursing bed posture, enabling normal nursing bed functions.

[0049] Reference Figure 2 The second mode: both the headboard 11 and the footboard 12 are lowered, which is the head-low and tail-low state, so that the bed body 13 of the nursing bed is lowered to an ultra-low position, making it easier for nursing staff to approach the patient and carry out nursing and monitoring work.

[0050] Reference Figure 3 The third mode: the headboard 11 is raised and the footboard 12 is lowered, which is a head-high-tail-low state, making it convenient for nursing staff to assist patients in getting up, transferring and other nursing work.

[0051] Reference Figure 4The fourth mode: the headrest 11 is lowered and the footrest 12 is raised. At this time, the head is lower and the foot is higher, which is suitable for special nursing needs. For example, for some patients with lower limb paralysis, this posture can promote the circulation and drainage of body fluids and reduce edema in the lower limbs.

[0052] Reference Figure 5 In this embodiment, the installation methods between the bed frame 13 and the headboard 11 and between the bed frame 13 and the footboard 12 are the same, and they are all detachably connected by connectors 5. The number of connectors 5 on each side is two that are spaced apart.

[0053] Reference Figure 6 The connector 5 includes a first connecting part 51 and a second connecting part 52. The first connecting part 5 is used to connect with the bed frame 13, and the second connecting part 52 is used to connect with the corresponding headboard 11 or footboard 12.

[0054] In one embodiment, the first connecting part 51 is a horizontal square rod. Correspondingly, a connecting cylinder 53 is fixedly installed on the bed 13. The connecting cylinder 53 is a horizontal square tube. The first connecting part 51 is inserted into the connecting cylinder 53 and locked by a locking member. In this embodiment, the locking member is a locking screw 54. There are two locking screws 54, which are spaced apart along the length of the connecting cylinder 53. The locking screws 54 pass through the top of the connecting cylinder 53 from top to bottom and are threaded to the first connecting part 51, so that the first connecting part 51 and the bed 13 form a horizontally combined detachable connection. This allows the worker to detach the connection between the bed 13 and the corresponding headboard 11 and tailboard 12 by pulling laterally during disassembly, which facilitates disassembly and assembly.

[0055] Because there is a space allowance between the first connecting part 51 and the connecting cylinder 53, relative friction can easily occur between them during actual use, generating harsh noise. This noise is particularly noticeable during different posture changes of the nursing bed, severely impacting the user experience. Therefore, in this embodiment, a sound-absorbing pad 55 made of TPE material is installed at the connection point between the connecting cylinder 53 and the first connecting part 51 to reduce noise at that location and improve the user experience.

[0056] In one embodiment, the second connecting portion 52 is in the shape of a vertical plate, and a first hanging interface 521 and a second hanging interface 522 are provided on the second connecting portion 52. Both the first hanging interface 521 and the second hanging interface 522 are located on the side of the second connecting portion 52 away from the first connecting portion 51. The first hanging interface 521 is located at the bottom with its opening facing downwards; the second hanging interface 522 is located at the top, and its opening extends vertically downwards for a certain distance before tilting downwards and penetrating to the side of the second connecting portion 52. Correspondingly, a first hook 523 and a second hook 524 are fixedly installed on the headboard 11 and the footboard 12, and the first hook 523 and the second hook 524 are arranged vertically at intervals to allow the first hanging interface 521 and the second hanging interface 522 in the second connecting portion 52 to be hooked one-to-one, so that the first hook 523 is hooked into the first hanging interface 521 and the second hook 524 is hooked into the second hanging interface 522.

[0057] In this embodiment, the downwardly inclined extension of the second hook interface 522 is flared from the inside out so that the second hook 524 can be inserted and hooked in cooperation with it. The opening positions of the first hook interface 521 and the second hook interface 522 are both rounded to remove the sharpness of the first hook interface 521 and the second hook interface 522, so as to facilitate the insertion and hooking of the first hook 523 and the second hook 524, and at the same time, to prevent them from scratching the assembly workers during disassembly and assembly.

[0058] Reference Figure 6 In this embodiment, a locking member 56 is installed on the second connecting part 52. Correspondingly, the headboard 11 and footboard 12 are provided with locking ports 57 for the locking member 56 to be plugged in and fixed. The locking member 56 is arranged inside the second hanging interface 522, so that the first hanging nail 523, the second hanging nail 524 and the locking member 56 form a triangular arrangement. On the one hand, by cooperating with the locking member 56 and the locking port 57, the second connecting part 52 can be fixedly connected to the corresponding headboard 11 or footboard 12. On the other hand, since the first hanging nail 523, the second hanging nail 524 and the locking member 56 form a triangular arrangement, the connection stability between the connecting member 5 and the corresponding headboard 11 or footboard 12 can be further guaranteed, making it less likely to generate abnormal noise during use.

[0059] Reference Figure 7Specifically, the locking component 56 includes a locking sleeve 561 and a locking rod 562. The locking sleeve 561 is threadedly connected to the second connecting part 52 and passes through the second connecting part 52. The locking rod 562 is installed inside the locking sleeve 561 in a stepped shaft shape, with a smaller head and a larger tail. A rod head 563 is installed at one end of the locking rod 562, and the rod head 563 is threadedly connected to the locking rod 562. A return spring 564 is installed inside the locking sleeve 561, with one end of the return spring 564 abutting against the stepped surface in the locking rod 562 and the other end abutting against the inside of the rod head 563.

[0060] During assembly, when the connector 5 is attached to the corresponding headboard 11 or footboard 12, the tail of the locking rod 562 passes through the connector 5 and is inserted into the locking port 57 under the action of the return spring 564, so as to lock the connector 5 to the corresponding headboard 11 or footboard 12.

[0061] In this embodiment, the inner end face of the rod head 563 is integrally formed with a limiting piece 565. There are two limiting pieces 565, which are arranged symmetrically from top to bottom. Correspondingly, the locking sleeve 561 has two limiting ports 566 at its outward end, which are also arranged symmetrically from top to bottom, so as to allow the two limiting pieces 565 to slide and engage, thereby limiting and controlling the inward insertion distance of the locking rod 562.

[0062] In this embodiment, a pre-tightening washer 567 is also installed between the locking sleeve 561 and the second limiting part, and the pre-tightening washer 567 is made of polyurethane material to further increase the frictional pre-tightening force after the locking sleeve 561 is installed, so as to improve its installation stability.

[0063] Reference Figure 8 In this embodiment, the back-raising mechanism 2 includes a back support plate 21 and a back-raising drive component 22. The back support plate 21 is partition-shaped and is installed on the side of the bed frame 13 near the headboard 11, with one inward-facing end rotatably connected to the bed frame 13. The back-raising drive component 22 is installed between the bed frame 13 and the back support plate 21 and is used to control the back support plate 21 to swing up or down. In this embodiment, the back-raising drive component 22 is an electric push rod, with one end hinged to the bed frame 13 and the other end connected to the bottom of the back support plate 21. When performing nursing care, caregivers can choose to raise the back support plate 21 by controlling the back-raising drive component 22 to lift the patient's back, facilitating subsequent feeding, drinking, cleaning, and other nursing tasks.

[0064] Reference Figure 8In this embodiment, the leg-bending mechanism 3 includes a thigh support plate 31, a calf support plate 32, and a leg-bending drive component 33. Both the thigh support plate 31 and the calf support plate 32 are partition-shaped, arranged on the side of the bed frame 13 near the footrest 12, with the thigh support plate 31 positioned inwards and the calf support plate 32 positioned outwards. The ends of the thigh support plate 31 and the calf support plate 32 are rotatably connected, while the end of the thigh support plate 31 away from the calf support plate 32 is rotatably connected to the bed frame 13. The leg-bending drive component 33 is installed between the bed frame 13 and the thigh support plate 31 and is used to control the thigh support plate 31 to swing up or down. In this embodiment, the leg-bending drive component 33 is an electric push rod, with one end hinged to the bed frame 13 and the other end connected to the bottom of the thigh support plate 31.

[0065] When performing nursing care, nurses can choose to raise the thigh support plate 31 by controlling the leg flexion drive 33, so that the thigh support plate 31 and the calf support plate 32 form a "︿" shape, which helps the patient to perform leg flexion activities, helps the patient's lower limb movement, promotes blood circulation, makes the lower limb less prone to stiffness, and is conducive to the patient's recovery.

[0066] Reference Figure 8 In this embodiment, a leg-lifting support rod 6 is installed between the bed 13 and the calf support plate 32. When the legs are bent, the caregiver can lift the calf support plate 32 again to lift the calf or even flatten the calf. Under the action of the leg-lifting support rod 6, the calf support plate 32 maintains a supporting state to help the patient maintain the leg-lifting state. In the bent-leg state, it releases the foot support force of the patient to help the patient maintain a more lasting leg-lifting posture.

[0067] Reference Figure 9 Specifically, the leg support rod 6 includes a rod body 61 and a rod sleeve 62. The rod body 61 is slidably and telescopically inserted into the rod sleeve 62, and the tail of the rod sleeve 62 is hinged to the bed 13. A guide groove 63 is provided inside the rod sleeve 62, and the guide groove 63 extends along the length of the rod sleeve 62. A locking port 64 is provided inside the guide groove 63, and the locking ports 64 are arranged at intervals along the length of the guide groove 63.

[0068] Reference Figure 10 and Figure 11 The tail of the rod 61 is equipped with a locking member 65 and a switch member 66. When the lower leg support plate 32 is lifted, the switch member 66 releases the locking member 65, and the locking member 65 moves along the guide groove 63 and falls into any locking port 64. After the pull stops, it locks itself in the locking port 64. When the lower leg support plate 32 is lowered, the switch member 66 locks the locking member 65, and the locking member 65 moves along the guide groove 63 to reset.

[0069] Reference Figure 10Specifically, the locking component 65 includes a swing hook 651, a locking pin 652, and a locking spring 653. The tail of the rod 61 has a through-hole swivel opening 654. The swing hook 651 is installed within the swivel opening 654, and the swing hook 651 and the swivel opening 654 can be movably engaged, allowing the swing hook 651 to be swivelly installed within the swivel opening 654 in the rod 61. The locking pin 652 is installed on the swing hook 651 to swing with it. The locking spring 653 is installed within the swivel opening 654, with its bottom connected to the inner bottom surface of the swivel opening 654 and its top connected to the bottom of the swing hook 651, applying an upward swivel preload to the swing hook 651.

[0070] Reference Figure 11 Correspondingly, a movable limiting port 661 is formed between the tail of the rod 61 and the sleeve 62. The switch 66 is slidably installed in the movable limiting port 661 and moves in the same direction as the rod 61. In this embodiment, the bottom of the switch 66 is a rod-shaped elastic pre-tightening part 662. A pre-tightening spring 663 is installed inside the switch 66, and the bottom of the pre-tightening spring 663 is pressed down and connected to the end of the elastic pre-tightening part 662 to control the elastic deformation of the elastic pre-tightening part 662 and press it against the inner wall of the sleeve 62, so that the switch 66 and the sleeve 62 are pre-tightened, making it difficult for them to move relative to the rod 61 spontaneously. The switch 66 has a locking port 664 and a movable port 665. The locking port 664 is connected to the movable port 665, and the locking port 664 is arranged closer to the tail of the rod 61. The locking opening 664 is small and fits the locking stop; the movable opening 665 is large to allow the locking stop to swing.

[0071] When the calf support plate 32 is lifted, the lever 61 extends outward. At this time, the switch 66 moves relative to the lever 61 towards the tail end, and the locking pin 652 slides out from the locking slot 664 into the movable slot 665 to unlock. The locking pin 652 then moves along the guide groove 63 and can fall into either locking slot 64. After the outward pulling stops, it locks in the corresponding locking slot 64, thus completing the re-lifting of the calf support plate 32 and assisting the patient in lifting their leg.

[0072] When the lower leg support plate 32 needs to be lowered to restore its original position, the outer rod 61 is first pulled to its limit position. At this time, the locking pin 652 falls back to the right end position in the guide groove 63. Then the lower leg support plate 32 is lowered, and the rod 61 is restored and retracted. At this time, the switch 66 moves away from the tail of the rod 61 relative to the rod 61. The locking pin 652 slides from the movable opening 665 into the locking opening 664 to lock. At this time, the lock cannot move or swing. It can only move and reset along the guide groove 63 until it is restored to the bent leg position. When the bent leg is restored again, the bent leg drive 33 controls the thigh support plate 31 and the lower leg support plate 32 to restore to the initial flat position.

[0073] The implementation principle is as follows:

[0074] Firstly, in actual use, the nursing bed can be used in four different modes through the lifting drive component 45 in the headboard 11 and footboard 12.

[0075] In the first mode, both the headboard 11 and the footboard 12 are raised, which is the normal nursing bed posture, enabling normal nursing bed functions.

[0076] Second mode: Both the headboard 11 and the footboard 12 are lowered, resulting in a head-low and tail-low position. This lowers the bed body 13 to an ultra-low position, making it easier for nursing staff to approach the patient and perform nursing and monitoring duties.

[0077] The third mode: the headboard 11 is raised and the footboard 12 is lowered, which is the head-high and foot-low position, making it convenient for nursing staff to assist patients in getting up, transferring and other nursing work.

[0078] Fourth mode: The headboard 11 is lowered and the footboard 12 is raised. At this time, the head is lower and the foot is higher, which is suitable for special nursing needs. For example, for some patients with lower limb paralysis, this posture can promote the circulation and drainage of body fluids and reduce edema in the lower limbs.

[0079] Secondly, when performing nursing care, nurses can choose to lift the back support board 21 by controlling the back lifting drive 22 to lift the patient's back so that subsequent nursing care such as eating, drinking, and cleaning can be carried out.

[0080] Thirdly, when nursing staff are performing nursing work, they can choose to raise the thigh support plate 31 by controlling the leg bending drive 33, so that the thigh support plate 31 and the calf support plate 32 form a "︿" shape, which helps the patient to perform leg bending activities, helps the patient's lower limb movement, promotes blood circulation, makes the lower limb less prone to stiffness, and is conducive to the patient's recovery.

[0081] Fourthly, in the bent-leg position, the nurse can lift the calf support plate 32 again to lift the calf or even flatten it. With the support of the leg lifting support rod 6, the calf support plate 32 maintains a supporting state to help the patient maintain the leg-raising position. In the bent-leg position, it releases the foot support force to help the patient maintain a more sustained leg-raising posture.

[0082] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
