Description

Technical Field

[0001] This invention belongs to the field of intelligent rehabilitation equipment technology, specifically relating to a multifunctional care and rehabilitation bed. Background Technology

[0002] With the increasing aging of the population, the proportion of elderly people in my country's total population is also growing. Statistics show that by 2030, the number of elderly people will reach 400 million, accounting for 26% of the population. The incidence of diseases causing lower limb dysfunction, such as hemiplegia and paraplegia, requiring long-term care, is much higher in the elderly than in young adults, significantly increasing the number of patients needing long-term care. When caring for these patients with lower limb dysfunction, it is necessary not only to meet their daily living needs but also to consider their rehabilitation. Patients need to undergo lower limb rehabilitation exercises (such as standing, squatting, and leg raises) to prevent osteoporosis, improve cardiopulmonary function, and prevent bedsores. In traditional medical care, caregivers manually move patients to rehabilitation equipment (such as standing frames), consuming a large amount of caregiver labor. Furthermore, multiple caregivers are needed to provide rehabilitation care for a single patient with lower limb dysfunction, resulting in a significant waste of caregiver labor.

[0003] In recent years, some rehabilitation beds have emerged to reduce the physical labor of caregivers. Hospital rehabilitation beds can be divided into two categories. One type is the daily living care rehabilitation bed, which reduces the burden of daily care by enabling patients to perform common postures (such as sitting up, bending legs, and turning over), or is a bed-chair integrated rehabilitation bed that allows switching between wheelchairs and nursing beds, reducing the effort caregivers need to move patients. The other type is the rehabilitation care rehabilitation bed designed to reduce the labor of caregivers in patient rehabilitation training. For example, standing beds that allow patients with lower limb dysfunction to perform lower limb rehabilitation training belong to this category. Most standing beds, as rehabilitation equipment, only have standing functions. Often, when patients need lower limb rehabilitation training, caregivers move them from a regular rehabilitation bed to the standing bed for lower limb movement rehabilitation, and then move them back to the regular rehabilitation bed afterward. This repeated moving is physically demanding and consumes a lot of energy. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multifunctional care and rehabilitation bed to address the shortcomings of the prior art, thereby reducing the pressure of manual care by frequently changing beds when patients with lower limb dysfunction switch between daily care and lower limb rehabilitation training.

[0005] The present invention adopts the following technical solution: The bed adopts a double-frame structure, including a fixed bed frame and a standing bed frame connected to one end of the fixed bed frame. The fixed bed frame is equipped with a back-raising module, a turning module, and a lifting module, while the standing bed frame is equipped with a leg-bending module, a standing module, a lower limb rehabilitation training module, and a locking module. The fixed bed frame is used for daily living care, while the standing bed frame is used for lower limb rehabilitation training.

[0006] Specifically, the backrest module is hinged to the backrest push rod mounting hole and the backrest drive rod mounting hole at the front of the fixed bed frame; the turning module is hinged to the turning push rod mounting hole and the turning triangle mounting hole in the middle of the fixed bed frame; the fixed bed frame standing rotation hole at the end of the fixed bed frame is hinged to the standing rotation hole at the rear of the standing bed frame; the front and rear legs of the lifting module are fitted to the back of the fixed bed frame through slots, and the middle leg and push rod of the lifting module are hinged to the back of the fixed bed frame.

[0007] Furthermore, the backrest module includes a backrest push rod, the tail of which is hinged to a backrest push rod mounting hole on the fixed bed frame, and the head of which is hinged to the middle of the backrest drive rod, which is hinged to a backrest drive rod mounting hole on the fixed bed frame. When performing backrest operation, the power supply drives the backrest push rod to extend and rotate the backrest drive rod, which in turn pushes the backrest plate to rotate to achieve the backrest function. Backrest side plates are provided on both sides of the backrest plate, and the angle between the backrest side plates and the backrest plate is 30°.

[0008] Furthermore, the turning module includes a turning push rod, the tail of which is mounted on the fixed bed frame. The head of the turning push rod is hinged to one side of the turning drive rod, and the other side of the turning drive rod is hinged to the turning triangle. The turning triangle is hinged to the turning triangle mounting hole on the fixed bed frame. When turning over, the power supply drives the turning push rod to move the turning drive rod, causing the turning triangle to rotate around a fixed point on the fixed bed frame. The turning triangle then drives the back panel and hip panel to rotate, and the hip panel then drives the back panel and back side panel to rotate, thus achieving the turning over.

[0009] Furthermore, the lifting module includes six bed legs. Among the six bed legs, the lower parts of the four head and leg legs are integrated with the base frame, and the upper parts are connected to the fixed frame through slots. The lower part of the middle bed leg is hinged to the base frame, and the upper part of the middle bed leg is hinged to the fixed bed frame. When a head-high, feet-low position is desired, the power-driven leg push rod remains stationary while the head push rod extends, enabling a reclining posture with the backrest raised. When a head-low, feet-high position is desired, the power-driven leg push rod extends while the head push rod remains stationary.

[0010] Specifically, the leg-bending module is hinged to the leg-bending push rod mounting hole on the side of the standing bed frame and the leg-bending parallel mounting hole in the middle and rear of the standing bed frame; the standing module is hinged to the standing push rod mounting hole in the middle of the standing bed frame; the bayonet module is fitted to the top of the standing bed frame and the top of the fixed bed frame; and the lower limb rehabilitation training module is hinged to the lower limb rehabilitation training drive rod mounting hole at the end of the standing bed frame.

[0011] Furthermore, the bayonet module includes a bayonet fixing block and a bayonet moving block. The bayonet fixing block is connected to the bayonet fixing block mounting hole of the fixed bed frame. The T-slot of the bayonet moving block is fitted to the boss of the bayonet moving mounting position. The bayonet moving block is fitted to the bayonet moving position on the standing bed frame. The bayonet extension block is connected to the back of the back panel.

[0012] Furthermore, the lower limb rehabilitation training module is a parallelogram linkage mechanism, including a lower limb rehabilitation training push rod. The tail of the lower limb rehabilitation training push rod is hinged to the lower limb rehabilitation training push rod mounting hole on the standing bed frame. The head of the lower limb rehabilitation training push rod is hinged to the tail of the lower limb rehabilitation training drive rod. The middle hole of the three lower limb rehabilitation training drive rods is hinged to the lower limb rehabilitation training drive rod mounting hole on the standing bed frame. The head of the lower limb rehabilitation training drive rod is hinged to the rear side of the squatting board. The bottom of the squatting board is hinged to a rehabilitation inclined plate. The foot inclination adjustment rod is hinged to the rehabilitation inclined plate. The other side of the foot inclination adjustment rod fits into the pre-reserved mounting groove on the squatting board.

[0013] Furthermore, the standing module includes a standing push rod, the head of which is hinged to a standing push rod mounting hole on the standing bed frame, and the tail of which is hinged to the base frame. When standing is activated, the power supply drives the standing push rod to work, which pushes the standing bed frame to rotate around a fixed point on the fixed bed frame to achieve standing. The standing bed frame is provided with slots for installing restraint straps and mounting holes for installing small table placement rods. The small table placement rods are used to place small tables when the standing bed frame is in a standing or lying position. The length of the standing push rod is adjustable.

[0014] Furthermore, the leg-bending module includes a leg-bending push rod. The tail of the leg-bending push rod is hinged to the leg-bending push rod mounting hole on the standing bed frame, and the head of the leg-bending push rod is hinged to one side of the single leg-bending drive rod. The other side of the leg-bending drive rod is hinged to the heads of two leg-bending parallel rods. The rotation hole of the leg-bending parallel rod is hinged to the leg-bending parallel rod mounting hole on the standing bed frame, and the tail of the leg-bending parallel rod is hinged to the lower side of the calf plate. During leg-bending operation, the power supply drives the leg-bending push rod to move the leg-bending drive rod, causing the leg-bending parallel rod to rotate around a fixed point on the standing bed frame, thereby causing the calf plate to move. The leg-bending parallel rod, thigh plate, calf plate, and standing bed frame form a parallelogram mechanism. The calf plate is always parallel to the standing bed frame during movement. The leg-lifting function is achieved by changing the direction of the push rod.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: A multifunctional care and rehabilitation bed offers diverse functions, including daily living assistance such as back raising, leg bending, turning over, reclining, head-up / foot-down, head-down / foot-up, and semi-sitting / lying positions for patients with lower limb dysfunction. It also provides lower limb rehabilitation training functions such as standing, squatting, leg raising while standing, and squatting while lying down, reducing the workload for caregivers. The lower limb rehabilitation training module is simple in principle, easy to maintain, safer, more reliable, and allows for natural function transitions. A locking module is designed to lock the standing bed frame and backrest in the standing position, and automatically disengages when not standing or when the standing position is cancelled, without affecting the patient's back raising and turning functions.

[0016] Furthermore, by controlling the back-lifting push rod, the patient's back is lifted, and a certain angle is created between the back side plate and the back plate to protect the patient on the back plate.

[0017] Furthermore, a push-back turning structure that puts less pressure on the patient's shoulders is adopted, and the patient's left and right turning is controlled by a single push rod through the turning triangle.

[0018] Furthermore, the six bed legs of the lifting module ensure safety, and the two push rods, through linkage control, can achieve head-high-feet-low, head-low-feet-high, and reclining positions for the patient.

[0019] Furthermore, the locking module ensures that the bed board will not tip over and cause injury to the user when the user is standing, and it automatically unlocks when returning to a lying position, without affecting the operation of the backrest and turning over functions.

[0020] Furthermore, the three lower limb rehabilitation training drive rods, squatting board, and standing bed frame in the lower limb rehabilitation module are arranged in a parallelogram structure, so that the squatting board is always perpendicular to the standing bed board. This allows the patient to squat and stand up, raise their legs, squat and stand up in a supine position, raise their legs in a supine position, and adjust the inclination of their feet to complete lower limb functional rehabilitation training.

[0021] Furthermore, the standing module enables the patient to stand.

[0022] Furthermore, the leg-bending module enables patients to bend and raise their legs. The lower leg plate, thigh plate, standing bed frame, leg-bending drive rod, and leg-bending parallel rod form a parallelogram structure, ensuring that the lower leg plate is always parallel to the buttock plate.

[0023] In summary, this invention enables daily care and rehabilitation training for patients with lower limb dysfunction, reducing the burden of manual care.

[0034] This invention provides a multifunctional care and rehabilitation bed, employing a double-frame structure, consisting of a standing bed frame 13 and a fixed bed frame 40. The standing rotation hole at the end of the fixed bed frame 40 is hinged to the standing rotation hole at the rear of the standing bed frame 13. The back-raising module, turning module, and lifting module are mounted on the fixed bed frame 40 and do not move with the standing bed frame 13 when in a standing position. The leg-bending module, standing module, lower limb rehabilitation training module, and locking module are mounted on the standing bed frame 13. The fixed bed frame 40 provides daily care for patients with lower limb dysfunction, while the standing bed frame 13 provides lower limb rehabilitation training for these patients.

[0035] Please see Figure 1 This invention discloses a multifunctional care and rehabilitation bed, comprising a back-raising module, a turning-over module, a leg-bending module, a standing module, a lower limb rehabilitation training module, a locking module, and a lifting module. The multifunctional care and rehabilitation bed adopts a double-frame structure, consisting of a standing bed frame 13 and a fixed bed frame 40. The end of the fixed bed frame 40 is hinged to the middle and rear part of the standing bed frame 13. The back-raising module, turning-over module, and lifting module are mounted on the fixed bed frame 40 and do not move with the standing bed frame 13 when in a standing position. The leg-bending module, standing module, lower limb rehabilitation training module, and locking module are mounted on the standing bed frame 13. The fixed bed frame 40 provides daily care for patients with lower limb dysfunction, while the standing bed frame 13 provides lower limb rehabilitation training for these patients.

[0036] The back-raising module enables the patient to raise their back. It is mounted on the fixed bed frame 40. The back-raising drive rod 17 is not hinged to the back panel 2 or the back side panel 3. When the back-raising function is needed, the control console issues a command, and the power supply drives the back-raising push rod 20 to move. This, in turn, causes the back panel 2 to rotate around the hip plate 15 via the back-raising drive rod 17 (a wheel can be added to the rod head to reduce friction), thus achieving the back-raising function. The back-raising angle reaches 80°, and the angle between the back side panel 2 and the back panel 2 is 30°.

[0037] The turning module is mounted on the fixed bed frame 40 and is not hinged to the bed board. It adopts a push-back turning method for upper body turning. Compared with the traditional "V"-shaped turning, the push-back turning method puts less pressure on the user's shoulders. When using the turning function, the control panel issues a command, and the power drives the turning push rod 22 to move, which in turn moves the turning drive rod 23. This, in turn, causes the turning triangle 21, which is in contact with the buttocks plate 15, to rotate. The turning triangle 21 pushes the buttocks plate 15 to rotate around the hinge of the non-rotating side plate 14, and also causes the back plate 2 to rotate together. At the junction of the side plate and the main plate, only unidirectional rotation is possible between the main plate and the side plate, which also avoids the problem that when turning over, the side plate on the turned-over side is vertically downward and cannot automatically return to its original position. By changing the direction of the push rod, turning in both directions can also be achieved. Both left and right turning can reach 30°.

[0038] The leg-bending module enables patients with lower limb dysfunction to bend and raise their legs.

[0039] To ensure that the calf board 11 remains parallel to the buttock board 15, the calf board 11, thigh board 12, standing bed frame 13, leg bending drive rod 28, and leg bending parallel rod 30 form a parallelogram structure. Since the calf board 11 needs to remain parallel to the buttock board 15 at all times, the parallelogram structure also needs to move when standing. Therefore, the leg bending module is installed on the standing bed frame 13. At the same time, to avoid conflict with the standing push rod 26, the leg bending push rod 24 is located on the right side of the bed, and two leg bending parallel rods 30 are installed on both sides. The leg bending parallel rods 30 and the leg bending push rod 24 are connected by the leg bending drive rod 28. This rod is shaped like an "F" with a horizontal bar added to the lower left side. The two horizontal bars of the "F" connect to the leg bending parallel rods 30, and the additional horizontal bar connects to the leg bending push rod 24. To ensure that the leg-bending structure does not conflict with other structures when in a lying position, a slot is provided on the fixed bed frame 40 to accommodate the leg-bending module in a lying position, while also ensuring that the leg-bending module moves without conflict when standing. When the leg-bending command is executed, the control console issues a command, and the power supply drives the leg-bending push rod 24 to work. The hinged leg-bending drive rod 28 moves, causing the leg-bending parallel rod 30 to move the lower leg plate 11 (different push rod directions can achieve upward or downward leg bending); when bending the leg downward, the angle between the thigh plate 12 and the buttock plate 15 can reach 70°, and when raising the leg, the angle between the thigh plate 12 and the buttock plate 15 can reach 25°.

[0040] The standing module enables standing rehabilitation training for patients with lower limb dysfunction.

[0041] When standing is required, the standing push rod 26 on the base frame 6 pushes the standing bed frame 13, causing the bed board on the standing bed frame 13 to stand up together. Unlike when the fixed bed frame 40 and the standing bed frame 13 are in contact when performing daily living care functions, this can be regarded as a single bed frame structure similar to that of a general care and rehabilitation bed. At this time, the standing bed frame 13 and the fixed bed frame 40 are separated. When standing is required, the control console issues a command, and the power drives the standing push rod 26 on the fixed bed frame 40, causing the standing bed frame 13 to rotate around the fixed bed frame 40 to a standing position. By adjusting the length of the standing push rod 26, different angles of head-high and feet-low positions and reclining positions without back support can also be achieved, with a maximum standing angle of 90°.

[0042] The locking module is installed on the standing bed frame 13. Since there is no hinge between the bed board and the bed frame, in order to ensure that the bed board will not tip over and cause injury to the user when standing at 90°, the locking module locks the bed board and bed frame to ensure safety when standing. It automatically unlocks when returning to the lying position, without affecting the operation of the backrest and turning over functions.

[0043] The locking module does not operate during relative movement between the backrest 2 and the standing bed frame 13, such as when the patient is sitting up or turning over. It operates during standing work, when there is relative movement between the standing bed frame 13 and the fixed bed frame 40, locking the backrest 2 and the standing bed frame 13 to prevent the bed from tipping over. The locking module automatically unlocks when the standing work ends and the standing bed frame 13 is lowered. The device consists of a locking fixing block 31 (mounted on the fixed bed frame 40), a locking extension block 38 (mounted on the backrest), and a locking moving block 32 (located between the backrest 2, the locking extension block 38, and the fixed bed frame 40; it does not contact the extension block in the lying position).

[0044] When in a lying position, the tail of the latch moving block 32 does not contact the latch extension block 38. The protrusion 39 at the front end of the latch moving block 32 is embedded in the slot of the latch fixing block 31. The latch moving block 32 is only engaged with the latch fixing block 31 on the fixed bed frame 40 and the standing bed frame 13, and is completely detached from the back panel. At this time, turning over, raising the back, and other operations will not cause the latch to move, so it will not affect the normal operation of the back panel 2. When standing is required for work, the standing bed frame 13 drives the locking block 32 to move. The ramps on the locking block 31 and the locking block 32 enable the locking block 32 to move synchronously upward with the standing bed frame 13 (the head of the bed moves upward when standing) and into the slot formed by the back panel 2 and the locking expansion block 38. When the standing bed frame 13 is completely separated from the fixed bed frame 40, the locking block 32 has completely moved into the slot of the standing bed frame 13, the back panel 2 and the locking expansion block 38, and enters the locked state.

[0045] When the standing position ends and the bed is lowered, the protrusion 39 on the ramp of the locking block 32 will first contact the slot of the locking block 31. Due to the ramp in the slot of the locking block, when moving downward, the locking block 32 will be "pulled" out of the slot of the back plate 2 and the locking extension block 38, and returned to the lying position, no longer affecting the movement between the bed board and the standing bed frame 13.

[0046] The lower limb rehabilitation training module enables patients with lower limb dysfunction to squat, stand up, and raise their legs, thereby completing the lower limb functional rehabilitation training function.

[0047] It consists of a lower limb rehabilitation training push rod 29, three lower limb rehabilitation training drive rods 10, and a squatting board 9. To ensure that the squatting board 9 is always perpendicular to the bed surface, a parallelogram mechanism is designed between the squatting board 9 and the standing bed frame 13, with three lower limb rehabilitation training drive rods 10 on each side. The dead point problem is solved through the multiple parallelogram structure.

[0048] Four casters 8 are installed at the head and foot of the base frame 6 to enable overall movement. In addition, two casters 8 are installed at the foot of the standing bed frame 13 so that there is a support point between the standing bed frame 13 and the ground when standing, ensuring safety when standing.

[0049] When there is no need to squat, the squatting board 9 is located at the foot of the bed, which can provide a foothold when standing, and can also serve as the foot of the bed when lying down; When squatting is required, the console issues a command, and the power drives the lower limb rehabilitation training push rod 29 to drive the lower limb rehabilitation training drive rod 10, which in turn drives the squatting board 9 to rotate around the fixed point on the standing bed frame 13, up to the position of the buttock board 15. When a person steps on the squatting board 9, the squatting board 9 drives the leg movement, thereby realizing the squatting rehabilitation training function. The lower limb rehabilitation training modules on both sides are controlled by two lower limb rehabilitation training push rods 29 respectively. By controlling the lower limb rehabilitation training push rods 29 through the control console, when one side of the squatting board 9 is working, the patient can realize the rehabilitation training of unilateral bent-leg squatting and leg raising. By controlling the periodic movement of the push rods on both sides, the patient with lower limb dysfunction can realize the cyclic leg raising rehabilitation exercise.

[0050] The lower limb rehabilitation training module can be used not only while standing, enabling patients with lower limb dysfunction to perform lower limb rehabilitation training in a standing position, but also while lying down. In the standing position, for rehabilitation purposes, it is sometimes necessary to adjust the angle between the patient's instep and the contact surface. Commonly used rehabilitation angles are 10°, 20°, and 30°. To achieve this, an inclined plate support structure is provided on the squatting board 9, allowing adjustment of the angle between the patient's instep and the board surface. The squatting height difference can reach 650mm, and the angle between the instep and the board surface can be adjusted from 10° to 30°.

[0051] To achieve overall height adjustment of the bed, patients with lower limb dysfunction can lie at an angle with their head lower than their feet. To avoid affecting the use of other daily living care functions of the bed, the lifting module is connected to the fixed bed frame 40 and the base frame equipped with casters. When the fixed bed frame 40 is raised or lowered, the relevant modules on the fixed bed frame 40, as well as the relevant modules on the standing bed frame 13 on the fixed bed frame 40 and the standing bed frame 13, will also be raised or lowered together, so it does not affect the realization of any function.

[0052] The lifting module consists of six bed legs and two push rods. Of the six bed legs, the lower parts of the four head and leg legs are integrated with the base frame, while the upper parts are connected to the fixed frame via slots. The lower part of the middle bed leg is hinged to the base frame, and the upper part is hinged to the fixed bed frame at a 40° angle. To achieve a head-high, feet-low position, the control panel issues a command, and the power drives the leg push rods to remain stationary while the head push rod extends, allowing for a reclining position with the backrest raised. To achieve a head-low, feet-high position, the control panel issues a command, and the power drives the leg push rods to extend while the head push rod remains stationary. Because the head support leg and leg support leg can only move vertically during operation, and their relative positions on the bed frame change, a slot connection is used. In the head-low, feet-high position, the maximum height difference between the foot of the bed and the headboard is 320mm, and in the reclining position, the maximum height difference is 100mm.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0054] Please see Figure 1 The bed board of the rehabilitation bed is placed on the standing bed frame 13. The bed board of the rehabilitation bed consists of nine bed boards (of which the leg side boards are integrated with the standing bed frame 13), namely the back board 2, back side board 3, hip board 15, hip side board 14, thigh board 12, and calf board 11. In the lying position, the standing bed frame 13 is placed on the fixed bed frame 40. The standing bed frame 13 and the fixed bed frame 40 are connected by the fixed bed frame standing rotation hole 409 on the fixed bed frame 40. The fixed bed frame 40 and the base frame 6 equipped with casters are connected by six bed legs. Please refer to [link to relevant documentation]. Figure 2 Of the six bed legs, the inner rods supporting the front leg 18 and the rear leg 27 are integrated with the base frame 6. The supporting legs are connected to the fixed bed frame 40 through support rod slots, ensuring that the bed legs are always perpendicular to the base frame 6, while allowing for some rotation and movement between the fixed bed frame 40 and the bed legs. The middle supporting legs 36 and 37 are hinged at both ends to the base frame 6 and the fixed bed frame 40, forming the main structure of the bed.

[0055] Please see Figure 5The fixed bed frame 40 is equipped with mounting holes 401 for locking blocks, 402 for batteries and control consoles, 403 for backrest lifting push rods, 404 for IV stands, 405 for guardrails, 406 for turning triangles, 407 for leg flexion modules, 408 for backrest lifting drive rods, and 409 for the fixed bed frame standing rotation. An IV stand 1 is installed in mounting hole 404 to facilitate injection procedures for patients. Guardrails 4 are installed in mounting holes 405 to ensure patient safety. Please refer to [link / reference needed]. Figure 3 The fixed bed frame 40 is equipped with a back-lifting module (back-lifting push rod 20, back-lifting drive rod 17), a turning module (turning push rod 22, turning drive rod 23, turning triangle 21), and a bayonet module (consisting of bayonet fixing block 31, bayonet moving block 32, bayonet expansion block 38, and connecting boss 39).

[0056] Please see Figure 6 The standing bed frame 13 has a bayonet moving block mounting position 131, a boss mounting hole 132, a restraint strap mounting hole 133, a small table placement rod mounting hole 134, a bent leg parallel rod mounting hole 135, a bent leg push rod mounting hole 136, a standing push rod mounting hole 137, a standing bed frame standing rotation hole 138, a lower limb rehabilitation training push rod mounting hole 139, and a lower limb rehabilitation training drive rod mounting hole 1310.

[0057] The small table placement rod 5 is installed on the small table placement rod mounting hole 134, which can be used to install the small bed board in the lying and standing positions for the convenience of the patient's daily use. The restraint belt mounting hole 133 is used to install restraint belts to protect the patient when the lower limb disability patient is standing.

[0058] Please see Figure 5 and Figure 6 The standing bed frame is equipped with a leg bending module (leg bending push rod 24, leg bending drive rod 28, leg bending parallel rod 30, calf board 11), a lower limb rehabilitation training module (lower limb rehabilitation training push rod 29, lower limb rehabilitation training drive rod 10, rehabilitation inclined board 33, foot inclination adjustment rod 34, locking switch 35, squatting board 9), a standing module (standing push rod 26, base frame 6, standing bed frame 13), a locking moving block 32 in the locking module and a boss 39 connected to the locking moving block 32, and a boss 39 in the locking module connected to the standing bed frame 13.

[0059] Please see Figure 7The backrest module consists of a backrest push rod 20, a backrest drive rod 17, a backrest plate 2, and a backrest side plate 3. The tail of the backrest push rod 20 is hinged to the backrest push rod mounting hole 403 on the fixed bed frame 40, and the head of the push rod is hinged to the middle of the backrest drive rod 17. The backrest drive rod 17 is hinged to the backrest drive rod mounting hole 408 on the fixed bed frame 40. When the backrest is raised, the control console issues a command, and the power drives the backrest push rod 20 to extend, which in turn drives the backrest drive rod 17 to rotate. The backrest drive rod 17 then pushes the backrest plate 2 to rotate, thus realizing the backrest raising function. Because there is an angle difference between the drive rods on both sides of the backrest drive rod 17 and the drive rod in the middle, when the backrest drive rod 17 pushes the backrest plate 2 to rotate, the backrest side plates 3 on both sides will be driven by the drive rod with a larger angle on the side of the backrest drive rod 17 and will rotate before the backrest plate 2. After completion, the backrest side plates 3 will be higher than the backrest plate 2 to protect the user. The backrest raising angle can reach 80°, and the angle between the backrest side plates 3 and the backrest plate 2 is 30°.

[0060] Please see Figure 8 The turning module consists of a turning push rod 22, a turning drive rod 23, a turning triangle 21, and a hip plate 2. The tail of the turning push rod 22 is mounted on the fixed bed frame 40, and the head of the turning push rod 22 is hinged to one side of the turning drive rod 23. The other side of the turning drive rod 23 is hinged to the turning triangle 21, which is hinged to the turning triangle mounting hole 406 on the fixed bed frame 40. When turning over, the control console issues a command, and the power drives the turning push rod 22. According to the direction of the push rod, the turning drive rod 23 moves, causing the turning triangle 21 to rotate around a fixed point on the fixed bed frame 40. The turning triangle 21 then drives the back plate 2 and the hip plate 15 to rotate, and the hip plate 15 then drives the back plate 2 and the back side plate 3 to rotate, thus achieving the turning effect. Changing the direction of the push rod 24 can achieve reverse rotation, and both left and right turning can reach 30°.

[0061] Please see Figure 10The leg-bending module consists of a leg-bending push rod 24, a leg-bending drive rod 28, a leg-bending parallel rod 30, a lower leg plate 11, and a thigh plate 12. The tail of the leg-bending push rod 24 is hinged to the leg-bending push rod mounting hole 136 on the standing bed frame 13. The head of the push rod is hinged to one side of the single rod of the leg-bending drive rod 28. The other side of the leg-bending drive rod 28 is hinged to the heads of the two leg-bending parallel rods 30. The rotation hole of the leg-bending parallel rod 30 is hinged to the leg-bending parallel rod mounting hole 135 on the standing bed frame 13. The tail of the leg-bending parallel rod 30 is hinged to the lower side of the lower leg plate 11. When the leg-bending operation is to be realized, the control console issues a command, and the power drives the leg-bending push rod 24. The leg-bending push rod then pushes the leg-bending drive rod 28 to move, causing the leg-bending parallel rod 30 to rotate around a fixed point on the standing bed frame 13, thereby causing the lower leg plate 11 to move. Since the leg-bending parallel rod 30, thigh plate 12, lower leg plate 11, and standing bed frame 13 form a parallelogram mechanism, the lower leg plate 11 is always parallel to the standing bed frame 13 during movement. Changing the direction of the push rod 24 can also realize the leg-raising function. When bending the leg downward, the angle between the thigh plate 12 and the buttock plate 15 can reach 70°. When raising the leg, the angle between the thigh plate 12 and the buttock plate 15 can reach 25°.

[0062] Please see Figure 11 The standing module consists of a standing push rod 26, a base frame 6, and a standing bed frame 13. The head of the standing push rod 26 is hinged to the standing push rod mounting hole 137 on the standing bed frame 13, and the tail is hinged to the base frame 6. When the standing position is activated, the control console issues a command, and the power supply drives the standing push rod 26 to work. The standing push rod 26 pushes the standing bed frame 13 to rotate around a fixed point on the fixed bed frame 40, achieving a standing position with a maximum standing angle of 90°. The standing bed frame 13 has slots 133 for restraint straps to protect the user and mounting holes 134 for a small table placement rod 5. The small table placement rod 5 can be used to place a small table when the standing bed frame 13 is in a standing or lying position, facilitating upper limb rehabilitation training or daily use. The length of the standing push rod 26 can also be adjusted to achieve different angles between the standing bed frame 13 and the fixed bed frame 40, allowing for different reclining postures. To ensure that the bed board will not tip over when standing, a locking module is installed on the standing bed frame 13 to ensure the safety of the equipment.

[0063] The bayonet module, designed to ensure equipment safety, comprises a bayonet moving block 32, a bayonet fixing block 31, a bayonet extension block 38, a boss 39, and a standing bed frame 13. The bayonet fixing block 31 connects to the bayonet fixing block mounting hole 401 on the fixed bed frame 40. The "T"-shaped groove of the bayonet moving block 32 engages with the boss 39 mounted on the bayonet moving mounting position 131. The bayonet moving block 32 also engages with the bayonet moving position 131 on the standing bed frame 13. The bayonet extension block 38 connects to the back of the back panel 2. (See also...) Figure 12The right figure shows the overall schematic diagram of the latch module. Figure AA shows the unlocked state when the patient is in a lying position, i.e., not standing. In this state, the latch is detached from the back panel 2, and it does not affect normal back raising or turning over. Figure BB shows the locked state when starting to stand up. At this point, the standing bed frame and the fixed bed frame have just completely separated. The latch module connects the back panel 2 and the standing bed frame 13 via the boss 39, preventing the back panel 2 from detaching from the standing bed frame 13. When the patient is in a lying position, the latch module is in the unlocked state. When raising or turning over, the standing bed frame 13 does not move; only the back panel 2 moves. Therefore, the latch moving block 38 will not move and will not affect the operation of the bed panel 2. When the standing push rod 26 is driven, it causes relative movement between the standing bed frame 13 and the fixed bed frame 40. The standing bed frame 13 causes the locking block 32 to move upward. Due to the inclined surface of the locking block 31, the locking block 32 moves into the slot between the back plate 2 and the locking expansion block 38. It is connected to the protrusion 39 on the standing bed frame 13 through the "T" groove on the locking block 32. When the locking block 32 is separated from the locking block 31, it has become integrated with the standing bed frame 13 and the back plate 2. Please refer to Figure BB. At this time, the locking block 31, the locking block 32, the back plate 2 and the standing bed frame 13 are connected as one, achieving the purpose. When the standing posture ends, the standing bed frame 13 is lowered, and the protrusion 39 on the locking block 32 will first enter the "T"-shaped hole reserved in the locking block 31. Driven by the locking block 31, the locking block 32 is pulled out from the space between the back panel 2 and the standing bed frame 13, canceling the locked state and returning to the unlocked state, without affecting subsequent work.

[0064] Please see Figure 13 and Figure 11The lower limb rehabilitation training module consists of a lower limb rehabilitation training push rod 29, a lower limb rehabilitation training drive rod 10, a rehabilitation inclined plate 33, a foot inclination adjustment rod 34, a locking switch 35, and a squatting plate 9. The tail of the lower limb rehabilitation training push rod 29 is hinged to the lower limb rehabilitation training push rod mounting hole 139 on the standing bed frame 13, and the head of the push rod is hinged to the tail of the lower limb rehabilitation training drive rod 10. The middle hole of the three lower limb rehabilitation training drive rods 10 is hinged to the lower limb rehabilitation training drive rod mounting hole 1310 on the standing bed frame 13. The head of the lower limb rehabilitation training drive rod 10 is hinged to the rear side of the squatting plate 9. The bottom of the squatting plate 9 is hinged to the rehabilitation inclined plate 33, and the foot inclination adjustment rod 34 is hinged to the rehabilitation inclined plate 33. The other side of the foot inclination adjustment rod 34 is fitted into the mounting groove reserved on the squatting plate 9. This device provides rehabilitation training for patients with lower limb dysfunction, including squatting and leg raising exercises. When in operation, the control console issues a command, powering the lower limb rehabilitation training push rod 7 to rotate the lower limb rehabilitation training drive rod 10. This causes the squatting board 9 to rotate around a fixed point on the standing bed frame 13. Because the three lower limb rehabilitation training drive rods form a multi-parallelogram mechanism (avoiding the influence of the four points of a parallelogram), the squatting board 9 remains perpendicular to the standing bed frame 13. The rehabilitation inclined plate 35 continuously moves towards the bed surface, thus achieving the patient's squatting posture. The lower limb rehabilitation training modules on both sides are controlled by two lower limb rehabilitation training push rods 29 respectively. By controlling the lower limb rehabilitation training push rods 29 through the control console, when one side of the squatting board 9 is working, the patient can achieve unilateral squatting and leg raising rehabilitation training. By controlling the periodic movement of the push rods on both sides, the patient can achieve cyclic leg raising rehabilitation exercises. The squatting board 9 is equipped with a rehabilitation inclined board 33 and a foot inclination adjustment rod 34. By manually adjusting the foot inclination adjustment rod 34, the angle between the user's foot and the board can be adjusted according to the user's different situation, and the angle can be changed to 10°, 20° and 30°, which plays a role in rehabilitation and correction for the patient. This module can be used not only when standing, but also when lying down, the squatting board 9 can be moved to realize the squatting position when lying supine, as well as leg raising and leg kicking training in the lying position.

[0065] Please see Figure 14The lifting module consists of a base frame 6, front support legs 18, a head drive push rod 19, a middle support leg 36, an inner rod 37 of the middle support leg 37, a rear support leg 27, a leg drive push rod 25, and a fixed bed frame 40. Both push rods have their heads hinged to the fixed bed frame 40, and their other sides are mounted on the frame of the base frame 6. The front support legs 18 and 27 fit into slots in the fixed bed frame 40. The curved support legs 18 and 27 engage with straight rods on the base frame 6. The inner rod 37 of the middle support leg 37 is mounted on the base frame 6 and engages with the inside of the middle support leg 36, which is hinged to the fixed bed frame. To achieve the commonly used head-down, feet-up position and reclining position with the backrest raised, the head drive push rod 19 and leg drive push rod 25 enable the overall lifting of the bed, allowing for the head-down, feet-up, and reclining positions with the backrest raised. When the head drive lever 19 is retracted, a command can be issued via the control console to power the leg drive lever 25, achieving a head-down, feet-up posture, with the foot of the bed up to 320mm higher than the headboard. When the leg drive lever 25 is retracted, a command can be issued via the control console to power the head drive lever 19, achieving a reclining position for the adjustable backrest 2, with the headboard up to 100mm higher than the footboard.

[0066] This invention can achieve the following usage states: Lying position; such as Figure 1 As shown, all bed boards are in a flat position, and the patient is lying flat on the bed.

[0067] Backrest position; such as Figure 7 As shown, when the back lift push rod 20 extends, the back lift push rod 20 drives the back lift drive rod 17 to rotate, lift the back plate 2, and at the same time lift the back side plate 3. The back side plate 3 protects the patient in the middle, thereby protecting the patient.

[0068] Rolling over; such as Figure 8 and Figure 9 As shown, when the turning push rod 24 extends or retracts, the turning push rod drives the turning drive rod 23 to move, thereby driving the turning triangle 21 to rotate, which in turn drives the hip plate 15 to rotate. The hip plate 15 then drives the back plate 2 and the hip side plate 14 through the hinge. The back plate 2 drives the back side plate 3 to rotate, thus realizing the patient's turning position.

[0069] Bent-leg position; such as Figure 10 As shown, when the leg-bending push rod 24 retracts, the leg-bending push rod 24 drives the leg-bending drive rod 28 to move, which in turn drives the leg-bending parallel rod 30 to rotate. The leg-bending parallel rod 30 pulls the lower leg plate 11 downward, thus enabling the patient to bend their leg.

[0070] The patient is in a supine position with legs bent. When the leg-bending push rod 24 extends, the lower leg plate 11 moves upward, enabling the patient to achieve supine leg-bending function.

[0071] Standing position; such as Figure 11As shown, when the standing push rod 26 extends, it pushes the standing bed frame 13 to rotate around the fixed bed frame, enabling the patient to stand. The standing bed frame 13 is equipped with restraint strap placement holes 133 and a small table placement rod 5 for placing a small table. Figure 13 When standing, the angle between the patient's foot and the board surface can also be controlled by adjusting the angle between the squatting board 9 and the rehabilitation inclined board 33.

[0072] reclining position; such as Figure 11 As shown, when the standing push rod 26 is not fully in the standing position, the bed can be in a reclining position.

[0073] Squatting position; such as Figure 13 As shown, when the patient is standing, when the lower limb rehabilitation training push rod 7 extends, it pushes the lower limb rehabilitation training drive rod 10 to rotate, thereby raising the squatting board 9 and enabling the patient to squat.

[0074] Leg-raising position; such as Figure 13 As shown, when standing, the patient can perform cyclic leg raises by controlling the lower limb rehabilitation training pushers 7 on both sides. The height and frequency of the leg raises can also be controlled by adjusting the extension length and duration of the lower limb rehabilitation training pushers 7.

[0075] Supine leg raise position; when the patient is in a supine position, the movement of the squatting board 9 can also be controlled by controlling the lower limb rehabilitation training push bar 7, thereby achieving the supine leg raise position when the patient is in a supine position.

[0076] Head down, feet up; such as Figure 14 When in a lying position, the head drive lever 19 retracts and the leg drive lever 25 extends, raising the foot of the fixed bed frame 40 and causing the standing bed frame 13 and the bed boards on it to rise and fall together, achieving a head-lower-feet-higher position.

[0077] Head-high-feet-low position: When in a lying position, the leg drive push rod 25 retracts and the head drive push rod 19 extends, raising the head of the fixed bed frame 40, which in turn raises and lowers the standing bed frame 13 and the bed boards on it, achieving the head-high-feet-low position.

[0078] In summary, this invention provides a multifunctional care and rehabilitation bed that enables patients with lower limb dysfunction to receive both daily care and lower limb rehabilitation training. It solves the problems of incomplete functionality in current care and rehabilitation beds and the need for frequent bed changes when switching between daily care and lower limb rehabilitation training for patients with lower limb dysfunction, thereby reducing the burden of manual care and improving social welfare.

[0079] The above content is only for illustrating the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solution based on the technical concept proposed in this invention shall fall within the scope of protection of the claims of this invention.
