Description

Technical Field

[0001] This invention relates to the field of patient-assisted standing bed technology, specifically a mobile assisted standing bed for paraplegic patients. Background Technology

[0002] For a long time, patients with paraplegia, severe paralysis, and other mobility impairments have faced the risk of complications such as muscle atrophy, joint contractures, pressure sores, deep vein thrombosis, and pulmonary infections due to prolonged bed rest. At the same time, about half of these patients experience psychological problems such as depression and anxiety, resulting in a significant decline in their quality of life. To improve this situation, standing beds, as assistive rehabilitation equipment, are widely used in rehabilitation centers, nursing homes, hospitals, and home care settings. They use electric or hydraulic mechanisms to lift patients from a supine position to an upright or sitting position, utilizing gravity to promote blood circulation, enhance the vitality of thoracic and abdominal organs, reduce the burden on caregivers, and improve the patient's independence.

[0003] While existing electric standing beds (such as CN118161358A and CN118924585A) can achieve passive standing training, they have significant shortcomings in terms of safety fixation and adaptability for completely paralyzed patients. Most devices use an integrated flat bed structure with poor conformity between the bed board and the physiological curvature of the human body, relying solely on simple restraint straps to secure the patient. When the bed rotates from a horizontal to a vertical position, the patient's body is prone to slipping through the gaps between the restraint straps and the bed board, or leaning forward and resting on the chest rail. Furthermore, the restraint structure of existing devices lacks targeted design, with dispersed support points for the shoulders, back, waist, hips, and legs, failing to provide comprehensive restraint for patients who have completely lost their ability to move independently. In addition, while some improved standing beds (such as CN219681060U) can provide some leg movement space, patients still need to have the ability to support their legs. For patients with complete leg paralysis, this not only fails to provide safe fixation but may also exacerbate the risk of slipping due to insufficient support. The core of these problems lies in the fact that existing equipment lacks an integrated restraint structure that conforms to the physiological characteristics of the human body, making it difficult to balance fixation safety and patient comfort, thus becoming a key bottleneck restricting the rehabilitation training and quality of life improvement of completely paralyzed patients. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a movable assisted standing bed for paraplegic patients, which solves the problems of low conformity between the bed board and the physiological curvature of the human body and the inability to provide all-round restraint for patients who have completely lost their ability to move independently.

[0023] Preferably, the connecting plate assembly includes two sets of parallel and symmetrically connected end-to-end rotating connecting plates one, two, three and four;

[0024] The connecting plate 1 is fixed and symmetrically arranged on both sides of the back frame of the support plate. The tail end of each connecting plate 1 is rotatably connected to the head end of a connecting plate 2, the tail end of each connecting plate 2 is rotatably connected to the head end of a connecting plate 3, and the tail end of each connecting plate 3 is rotatably connected to the head end of a connecting plate 4.

[0025] Two connecting plates 2 and two connecting plates 3 are respectively fixedly connected to the inner sides of the legs, and a total of four leg frames are provided for fixing the left and right thighs and calves; each leg frame is provided with the restraint component 2, and the inner sides of the tail ends of the two connecting plates 4 are respectively rotatably connected to the foot frames, and a total of two foot frames are provided; elastic bands are fixedly provided on both foot frames for foot fixation.

[0026] Preferably, the second restraint component includes a first fixing strap and a second fixing strap;

[0027] The first fixing strap is wrapped around the front side of the leg frame, and the second fixing strap is wrapped around the side or rear side of the leg frame; the inner side of the first fixing strap is the barbed side of the hook and loop fastener, and the outer side of the second fixing strap is the rough side of the hook and loop fastener. The inner side of the first fixing strap can be attached to the outer side of the second fixing strap, forming a restraining ring around the leg with the leg frame.

[0028] Preferably, the drive assembly includes a rotating rod that passes through the bottom of the support frame back frame and is rotatably connected to the support frame; each end of the rotating rod is connected to a first rope wheel via an electromagnetic clutch; the outer periphery of each of the first rope wheels is fixedly connected to the tail ends of the second connecting plates via two first traction ropes; the outer periphery of each of the first rope wheels is coaxially fixedly connected to a second rope wheel; the outer periphery of each of the second rope wheels is fixedly connected to the tail ends of the second connecting plates via two second traction ropes.

[0029] The drive assembly also includes a worm gear fixedly connected to the outer wall of the rotating rod; a screw is meshed at the bottom end of the worm gear, and the drive end of the second motor is fixedly connected to the rear end of the screw; the second motor is mounted at the bottom of the support frame back frame via a fixing bracket.

[0030] The electromagnetic clutches on both sides of the rotating rod operate in opposite states; the first and second rope pulleys on the same side have opposite winding directions.

[0031] Preferably, the bottom of the base frame is provided with casters; the middle of the long side outer wall of the rotating frame is provided with a handle; and the back frame is provided with a soft pad.

[0032] Working principle: The patient is transferred to the standing bed via a transfer bed. Then, the patient's chest is secured by restraint straps one and two and buckles, and the patient's waist and hips are secured by restraint strap three. Next, the patient's legs are placed on the corresponding leg rests, and the patient's thighs and calves on both sides are secured by fixing straps one and two respectively. Finally, the patient's feet are placed on the footrests and secured by elastic bands. Then, the rotating frame is raised and rotated according to a predetermined program by an electric telescopic rod, so that the patient's position changes from lying flat to standing. Then, motor one is started, which drives the gear to rotate. Under the meshing of the gear and rack, the movable bed board moves backward a certain distance along the slide on the support plate, so that the leg rests and footrests are detached from the movable bed board. As the gear continues to drive, the movable bed board will move upward along the slide. When it reaches the appropriate position, motor one is turned off. At this time, the leg rests and footrests are detached from the movable bed board and suspended in the air.

[0033] At this point, the patient is in an upright position. When performing leg-raising exercises, motor two is activated. When it is necessary to raise the patient's left thigh, the right electromagnetic clutch disengages, so that the right rope pulleys one and two are no longer driven by motor two. At this time, the left electromagnetic clutch is in a magnetic attraction state, and the rotating rod will drive the left rope pulleys one and two to rotate simultaneously. During rotation, the first traction rope is tightened, and the second traction rope is loosened. This allows the left connecting plate two to be controlled to rotate counterclockwise by a predetermined angle around its connection with the first connecting plate, thereby raising the patient's left thigh. Afterwards, motor two controls the rotating rod to rotate in the opposite direction. When the motor moves, the second connecting plate will slowly return to its original position, and then the second traction rope will be tightened while the first traction rope is loosened. The third connecting plate on the left side will rotate clockwise around the connection point with the second connecting plate by a predetermined angle, thus raising the patient's left lower leg. Similarly, when it is necessary to raise the patient's right leg, the left electromagnetic clutch will disengage, so that the first and second rope wheels on the left side are no longer driven by the second motor. At this time, the right electromagnetic clutch will be in a magnetic attraction state, and the rotating rod will drive the first and second rope wheels on the right side to rotate simultaneously. As above, the patient's right thigh will be raised by tightening the first traction rope, and the patient's right lower leg will be raised by tightening the second traction rope.

[0034] After the patient completes the training, medical staff can move the standing bed to the appropriate position by holding the handle and pushing it, and then control the standing bed to return to its original position.

[0035] This invention provides a movable assisted standing bed for paraplegic patients. It has the following beneficial effects:

[0036] 1. The present invention has human-shaped recesses on the fixed bed board and the movable bed board, and the support frame adopts a human-shaped structure that conforms to the physiological curve of the human body, providing comprehensive and stable support for patients during the process of standing up, effectively reducing the risk of patients slipping during the process of standing up;

[0037] 2. The binding strap 1, binding strap 2, binding strap 3 and Velcro fixing strap 1 and fixing strap 2 provided by the present invention provide full-body binding support points, realize all-round fitting and fixation of the shoulders, chest, waist, hips and legs, and do not require any part of the patient's body to provide independent support during the process of standing up and rotating, providing comprehensive support for patients who have completely lost the independent support function of the spine, lumbar spine and legs.

[0038] 3. The present invention uses a rotating frame with a fixed bed board and a movable bed board inside, as well as a structure in which the support frame and the bed board are flexibly fixed and separated. This allows the patient's torso and leg support structures to work together in a coordinated manner while remaining relatively independent. They work together in a horizontal state to complete the standing and rotation, and can be separated independently after standing up, allowing the patient's legs to suspend in the air, leaving ample space for training activities.

[0039] 4. This invention uses a traction rope structure and a continuously rotating connecting plate structure to simulate the traction control principle of human leg muscles on bones, assisting patients who have completely lost their voluntary muscle ability and are unable to stand independently to achieve basic leg training functions such as "raising the thigh forward" and "raising the lower leg backward".

[0040] 5. The present invention has casters on the base frame and handles on the rotating frame. The rotating frame has the telescopic rod in the middle area as the rotation center, which effectively reduces the load-bearing risk during movement, reduces movement cost, and increases movement feasibility compared to the structure with the foot area as the rotation center.

[0041] 6. The invention has a built-in power module, which enables long-term paralyzed patients to be pushed out of the ward or indoors more frequently for outdoor training and social interaction. Attached Figure Description

[0054] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] Example:

[0056] Please see the appendix Figure 1 - Appendix Figure 11 This invention provides a mobile assisted standing bed for paraplegic patients, comprising: a base frame 1, a bed body assembly, and a support assembly.

[0057] The base frame 1 is connected to the bed frame assembly via three sets of electric telescopic rods 2. By driving the three sets of electric telescopic rods 2 to work together, the bed frame assembly can be raised and lowered relative to the base frame 1, or the bed frame assembly can be rotated from a horizontal position to an upright position and then back to a horizontal position.

[0058] The bed frame assembly includes a rotating frame 3; a fixed bed board 5 is fixedly connected to the inside of the rotating frame 3, and a movable bed board 6 is movably connected to the inside of the rotating frame 3; the fixed bed board 5 provides trunk support, and the movable bed board 6 provides leg support; the movable bed board 6 can be moved from a flat position alongside the fixed bed board 5 to the back of the fixed bed board 5 inside the rotating frame 3 via a moving assembly, so that the patient's legs are suspended in the air;

[0059] The support components include a headrest, armrests, and support frame 13 that conform to the human physiological structure; the headrest and armrests are set on the fixed bed board 5, and the support frame 13 is detachably connected to the fixed bed board 5 through a disassembly assembly;

[0060] The support frame 13 includes a torso assembly and a leg assembly. The torso assembly includes a back frame and a first restraint assembly, and the leg assembly includes a connecting plate assembly, a second restraint assembly, and a drive assembly.

[0061] like Figure 1 As shown, the base frame 1 is generally rectangular in shape, providing overall support for the bed frame assembly, the support components mounted on the bed frame assembly, and the patient's body. The rotating frame 3 is also generally rectangular in shape; three sets of electric telescopic rods 2 are symmetrically arranged on both sides of the base frame 1 and the rotating frame 3, corresponding to the head, middle, and foot areas, for a total of six electric telescopic rods 2. The central axes of the three electric telescopic rods 2 on the same side are coplanar, and the bottom ends of the two electric telescopic rods 2 in the same group are coaxial, meaning that the rotation angle of the two electric telescopic rods 2 in the same group is always the same, and they move synchronously on parallel vertical planes.

[0062] Specifically, the bottom ends of the two electric telescopic rods 2 located in the middle area are respectively set at the midpoint of the long sides of the base frame 1, and are fixedly connected to the electric controllers at corresponding positions inside the base frame 1. Their top ends are rotatably connected to the outer wall of the midpoint of the long side of the rotating frame 3. The electric controllers at these positions can control the two electric telescopic rods 2 in the middle group to perform synchronous lifting and lowering movements, and keep their lifting and lowering heights consistent. The two electric telescopic rods 2 in this group cannot rotate around their bottom ends, and their top ends serve as the rotation centers of the long sides of the rotating frame 3, providing reference support.

[0063] The bottom ends of the two electric telescopic rods 2 located in the head area are rotatably connected to the electric controller in the head area inside the base frame 1 via a common rotating shaft, and their top ends are rotatably connected to the outer wall of the long side of the head area of ​​the rotating frame 3. The electric controller at this position can control the synchronous extension and retraction of the two electric telescopic rods 2, and can also control the synchronous rotation of the two electric telescopic rods 2 by controlling the rotation angle of the common rotating shaft. The bottom ends of the two electric telescopic rods 2 located in the foot area are rotatably connected to the electric controller in the foot area inside the base frame 1 via a common rotating shaft, and their top ends are rotatably connected to the outer wall of the long side of the foot area of ​​the rotating frame 3. The electric controller at this position can control the synchronous extension and retraction of the two electric telescopic rods 2, and can also control the synchronous rotation of the two electric telescopic rods 2 by controlling the rotation angle of the common rotating shaft.

[0064] When the three sets of electric telescopic rods 2 are in their initial state, all three sets are vertical and at the same height, while the rotating frame 3 and its inner bed are horizontal. Pressing the raise / lower button on the remote control allows the three sets of electric telescopic rods 2 to rise and fall synchronously on the vertical plane; releasing the button locks the three sets of electric telescopic rods 2 at their current height. By pressing or releasing the raise / lower button, the plane of the rotating frame, its inner bed, and the support frame 13 can be aligned with the surface of the target hospital bed.

[0065] After the patient is transferred to the assisted standing bed and secured, press the standing switch on the remote control. This causes the three sets of electric telescopic rods 2 to work together: first, the entire bed surface is raised to a suitable height for rotation; then, the two electric telescopic rods 2 in the middle area remain locked at their current height, serving as the central axis support for rotation; the two sets of electric telescopic rods 2 on the head and feet sides work together, using their respective bottom common rotation axis as the central axis, to deflect and extend towards the middle area, jointly driving the rotating frame 3 to rotate with the head raised and feet lowered, until the rotating frame 3 and the inner side of the bed reach the preset upright position. All three sets of electric telescopic rods 2 remain locked. Figure 11 As shown.

[0066] During the standing process, the coordinated extension and rotation of the three sets of electric telescopic rods 2 are carried out synchronously, and their respective rotation speed and extension speed need to be calibrated and determined. The rotating frame 3 serves as the connecting carrier between the bed board and the telescopic rods, and its two long sides are rotatably connected to the top of the electric telescopic rods 2 to ensure a smooth rotation process.

[0067] The base frame 1 has a built-in power module that supplies power to all motor drives and control components of the device. Once charged, this built-in power module allows the device to operate normally outdoors, independent of indoor power supply environments. The bottom of the base frame 1 is equipped with casters 40, each with a brake mechanism. A handle 4 is fixedly connected to the front end of the rotating frame 3. Locking the casters 40 secures the auxiliary lifting bed in place; releasing the casters 40 allows the auxiliary lifting bed to be moved freely using the handle 4 and the casters 40.

[0068] It should be noted that most existing standing beds use the foot area as the rotation center. With this structure, after the bed is upright, the center of gravity of the bed and the patient's torso naturally shifts towards the foot area of ​​the base frame, not completely coinciding with the center of gravity of the base frame for balance. This increases the overall weight-bearing risk during movement, and the handles suitable for pushing are located a considerable distance from the head boundary of the base frame, often requiring two caregivers to push the bed from both sides. In contrast, this invention uses the telescopic rod in the middle area as the rotation center. After the bed is upright, the center of gravity of the rotating frame, bed body, support frame, and patient's torso is aligned vertically with the center of gravity of the base frame. Furthermore, the handles for pushing are located at the center of the center of gravity plane, closer to the head boundary of the base frame. This reduces the overall weight-bearing risk during movement and makes single-person pushing possible.

[0069] A fixed bed board 5 is fixedly connected to the inner circumference of the rotating frame 3 corresponding to the patient's torso area. The fixed bed board 5 is fixedly connected to the rotating frame 3 via a fixed shaft and can rise, fall, or rotate synchronously with the rotating frame 3 to provide support for the patient's torso. Support plates 7 are symmetrically fixedly connected to the bottom of the long sides of the rotating frame 3. The inner surfaces of the two support plates 7 are respectively on the same vertical plane as the corresponding inner wall of the rotating frame 3, serving as extension surfaces of the inner wall of the rotating frame 3. A movable bed board 6 is movably connected between the inner surfaces of the rotating frame 3 and the two support plates 7, corresponding to the patient's leg area, via a moving component. The movable bed board 6 provides support for the patient's legs. In the initial state... The movable bed board 6 is temporarily kept in a parallel and flat position with the fixed bed board 5 via the movable axis. When the movable bed board 6 is in the initial state, the bottom center line of the movable bed board 6 is collinear with the bottom center line of the fixed bed board 5, and the corresponding sides are basically in contact. At this time, the movable bed board 6 can provide support for the patient's leg area. When the rotating frame 3 is rotated to be perpendicular to the base frame 1, all three sets of electric telescopic rods 2 are locked. After the patient completes the standing action in an upright position, the moving component is activated. The movable bed board 6 can be moved along the "L" shaped trajectory to the back of the fixed bed board 5 through the moving component, so that the patient's legs are in a suspended state.

[0070] Specifically, a guide plate 8 is fixedly connected to the top corner area of ​​the bottom surface of the movable bed board 6. A motor 9 is installed at the rear end of the guide plate 8 via a fixing frame. The drive end of the motor 9 passes through the guide plate 8 and is fixedly connected to a gear 10. The rear end of the gear 10 is rotatably connected to the front end of the guide plate 8. A rack 11 is meshed with the outer periphery of the gear 10. The rack 11 is fixedly connected to a groove 12 in the inner wall of the support plate 7. The groove 12 forms four sets of "L"-shaped slide rails. The short "L"-shaped arms are perpendicular to the bed board plane and extend in a direction away from the bed board surface. The long "L"-shaped arms are parallel to the bed board plane and extend towards the head of the bed. The four sets of "L"-shaped slide rails provide support and sliding tracks for the four bottom corners of the movable bed board 6. The rack 11 is L-shaped and matches the slide groove 12. The gear 10 meshes with the rack 11 under the drive of the motor 9 and makes an L-shaped movement in the slide groove 12. The cross section of the guide plate 8 matches the inner diameter of the slide groove 12 and can be partially engaged in the slide groove 12 to make an L-shaped movement synchronously. The guide plate 8 restricts the gear 10 in the slide groove 12 so that it cannot move away from the slide groove 12.

[0071] Preferably, two sets of moving components consisting of guide plates 8, motors 9, gears 10, and racks 11 can be respectively installed at the diagonal corners of the bottom of the movable bed plate 6 to provide diagonal meshing drive for the movable bed plate 6. For the diagonal areas where no moving components are installed, corresponding guide shafts or guide plates can be installed. Motors 9 at different corner positions maintain synchronous operation through calibration to ensure stable movement of the movable bed plate 6. Alternatively, four sets of moving components consisting of guide plates 8, motors 9, gears 10, and racks 11 can be respectively installed at the four corners of the bottom of the movable bed plate 6 to provide four-corner meshing drive for the movable bed plate 6.

[0072] A headrest is fixedly installed at the head position of the fixed bed board 5. The headrest is arc-shaped and is used to support the patient's head. An elastic headband is installed on the headrest to provide support for the patient's head and cervical spine when necessary.

[0073] The upper surface of the bed frame, composed of the fixed bed board 5 and the movable bed board 6, is padded, with corresponding human-shaped recesses. The support frame 13 is an overall human-shaped support, conforming to the physiological structure of the human body. The human-shaped recesses on the fixed bed board 5 and the movable bed board 6 match the bottom and side contours of the support frame 13. The bottom of the support frame 13 is connected to the fixed bed board 5 via a detachable assembly. Specifically, bolts 14 are fixed at the four corners of the bottom of the support frame 13, and through holes are made at the corresponding locations of the human-shaped recesses on the fixed bed board 5. The bolts 14 pass through the fixed bed board 5 and are threadedly connected to nuts 15. During use, the support frame 13 is fixedly installed on the fixed bed board 5 using bolts 14 and nuts 15 to prevent displacement. After use, the support frame 13 can be removed from the fixed bed board 5 by loosening the nuts 15 for easy cleaning, disinfection, or storage.

[0074] When the support frame 13 is installed on the fixed bed board 5, the support frame 13 can be embedded in the human-shaped recess on the upper surface of the fixed bed board 5 and the movable bed board 6, so that the support frame 13 is basically flush with the upper surface of the fixed bed board 5 and the movable bed board 6.

[0075] The upper part of the support frame 13 is equipped with a restraint component. Specifically, two restraint straps 16 for restraining the shoulders are respectively provided on both sides of the back frame of the support frame 13 corresponding to the upper end of the patient's shoulders, and two restraint straps 28 for restraining the chest are provided on both sides of the back frame of the support frame 13 corresponding to the patient's ribs. Buckles 17 are provided at the connection points of the restraint straps 16 and 28. The ends of the two restraint straps 16 are connected to the upper ends of the two restraint straps 28 via the buckles 17, and the middle connecting ends of the two restraint straps 28 can also be connected via the buckles 17. The restraint straps 16 extend downwards from the patient's shoulders to the chest, and the restraint straps 28 pass under the patient's armpits to the chest. The restraint straps 16 and 28 can tightly restrain the patient's upper torso to the back frame of the support frame 13.

[0076] The lower part of the back frame of the support frame 13 is equipped with a binding strap 3 19 for binding the patient's waist and hips. The binding strap 3 19 is shaped like a "T" belt. The upper ends of the vertical "T" belt are equipped with buckles 17 on both sides, which connect to the horizontal straps on both sides. The binding strap 3 19 provides binding support from the patient's waist and hips, tightly binding the patient's waist and hips to the waist and hip frame of the support frame 13.

[0077] The tightness of the first restraint belt 16, the second restraint belt 18, and the third restraint belt 19 can be adjusted through the buckle 17 to adapt to the restraint support needs of patients of different body types.

[0078] Handrails are correspondingly installed on the fixed bed boards 5 on both sides of the support frame 13. Specifically, an inverted "L"-shaped storage slot is provided on the upper part of the fixed bed board 5. A rotating shaft is fixedly installed on the inner side of the bottom apex of the inverted "L"-shaped storage slot. A rotating block 21 is rotatably connected to the rotating shaft, and an L-shaped frame 22 is rotatably connected to the top of the rotating block 21. The L-shaped frame 22 initially matches the inverted "L"-shaped storage slot and can be completely stored in the inverted "L"-shaped storage slot. When the L-shaped frame 22 is disengaged from the inverted "L"-shaped storage slot, it can rotate and open and close on an axis perpendicular to the central axis of the rotating block 21, and can be extended and retracted. The L-shaped frames 22 on both sides can be staggered above the chest of the support frame 13, pass under the patient's armpit, and form a barrier support on the lower part of the patient's upper arm and in front of the chest.

[0079] Two sets of connecting plate assemblies are symmetrically arranged on both sides of the central axis of the support frame 13 back frame, including connecting plate 1 23 fixedly connected to both sides of the support frame 13 back frame. The tail end of each connecting plate 1 23 is rotatably connected to the head end of a connecting plate 24, the tail end of each connecting plate 24 is rotatably connected to the head end of a connecting plate 3 25, and the tail end of each connecting plate 3 25 is rotatably connected to the head end of a connecting plate 4 26. Connecting plate 1 (23), connecting plate 2 (24), connecting plate 3 (25) and connecting plate 4 (26) are continuously rotatably connected from head to tail and are symmetrically and parallelly arranged on both sides of the support frame 13 to provide a transmission basis for the patient's leg training.

[0080] Leg supports 27 are fixedly connected to the inner sides of two connecting plates 24 and two connecting plates 3, respectively, for a total of four leg supports 27, which are used to provide fixed support for the patient's left and right thighs and calves; each leg support 27 is equipped with a restraint component 2; foot supports 30 are rotatably connected to the inner sides of the tail ends of two connecting plates 4 26, for a total of two foot supports 30; each foot support 30 is fixedly equipped with an elastic band for foot fixation.

[0081] Specifically, a first fixing strap 28 is provided around the front side of the leg frame 27, and a second fixing strap 29 is provided around the side or rear side of the leg frame 27. The inner side of the first fixing strap 28 is the barbed side of the hook and loop fastener, and the outer side of the second fixing strap 29 is the rough side of the hook and loop fastener. The inner side of the first fixing strap 28 can be attached to the outer side of the second fixing strap 29 to form a restraint ring around the leg with the leg frame 27.

[0082] The drive assembly includes a rotating rod 31, which passes through the bottom of the support frame 13 and is rotatably connected to the support frame 13. Both ends of the rotating rod 31 are connected to a first rope wheel 32 via an electromagnetic clutch 39. The outer periphery of the two first rope wheels 32 is fixedly connected to the tail ends of two second connecting plates 24 via a first pull rope 33. The outer periphery of the two first rope wheels 32 is coaxially fixedly connected to a second rope wheel 34. The outer periphery of the two second rope wheels 34 is fixedly connected to the tail ends of two third connecting plates 25 via a second pull rope 35.

[0083] The drive assembly also includes a worm gear 38 fixedly connected to the outer wall of the rotating rod 31; the bottom end of the worm gear 38 is meshed with a screw 37, and the rear end of the screw 37 is fixedly connected to the drive end of the second motor 36, which is mounted on the bottom of the support frame 13 via a fixing bracket.

[0084] The electromagnetic clutches 39 on both sides of the rotating rod 31 operate in opposite states, that is, when one electromagnetic clutch 39 is in the connected state, the other electromagnetic clutch 39 is in the disengaged state; the first rope wheel 32 and the second rope wheel 34 on the same side have opposite winding directions, that is, when the first rope wheel 32 is in the tightened state, the second rope wheel 34 on the same side is in the relaxed state, so that the patient's thigh and calf movements are coordinated.

[0085] The working principle of the leg training structure driven by the drive component in this invention is as follows: the second motor 36 drives the screw 37 to rotate, the screw 37 meshes with the worm gear 38 on the outer wall of the rotating rod 31, causing the rotating rod 31 to rotate. Through the electromagnetic clutches 39 on both sides of the rotating rod 31, the transmission state connecting the single-sided rope wheel 32 and the second rope wheel 34 can be independently controlled to achieve precise single-leg training. Taking the left thigh lift as an example: the right electromagnetic clutch 39 is disengaged, and the right rope wheel 1 32 and rope wheel 2 34 stop transmission; the left electromagnetic clutch 39 is magnetically locked, and the rotating rod 31 drives the rear rope wheel 1 32 to rotate, tightening the pull rope 1 33; the pull rope 1 33 is connected to the connecting plate 24, pulling the connecting plate 24 to rotate counterclockwise around the connection point of the connecting plate 1 23, thereby driving the left thigh to lift through the leg frame 27; at this time, the rope wheel 2 34 rotates synchronously, releasing the pull rope 2 35 to avoid pulling interference on the lower leg, so that the lower leg can follow the knee and thigh in motion; similarly, the reverse drive motor 2 36 can reset the left thigh; if the reverse drive motor 2 36 continues, the rope wheel 34 tightens the pull rope 2 35, and the connecting plate 3 25 rotates around the connecting plate 2 24, driving the left lower leg to lift, at which time the pull rope 1 33 is released again, so that the thigh can follow the knee and lower leg in motion; the right leg training is achieved by switching the magnetic state of the electromagnetic clutch 39, and the operation logic is the same.

[0086] The first traction rope 33 simulates the muscles on the front of the thigh, and the second traction rope 35 simulates the muscles on the back of the calf. Combined with the continuous connecting structures such as the first connecting plate 23, the second connecting plate 24, and the third connecting plate 25, they simulate the movement pattern of leg muscles pulling on bones, achieving the goal of leg training for paralyzed patients. Furthermore, to simulate the transmission function of leg muscle and bone movement in a more detailed way, multiple sets of separately controlled rotating rods 31 and worm gear drive structures can be set up, along with multiple sets of rope pulleys and traction ropes working together, as well as connecting plate structures, to more precisely simulate the movement patterns of leg muscles, ligaments, and bone joints.

[0087] The assisted standing bed device provided by this invention has soft pads or soft rubber structures in all areas that come into contact with the patient's body, improving patient comfort. Simultaneously, soft pads 20 conforming to human physiological structure are provided in the lumbar and hip areas of the support frame 13, especially in the area where the motor 2 36 contacts the support frame 13, and in the area where the restraint strap 3 19 contacts the patient's body. These pads provide restraint support while protecting the patient's lumbar and hip skin and bones, further enhancing patient comfort.

[0088] The specific usage process of this invention is as follows: When it is necessary to transfer a patient to this device, firstly, the device is pushed to the target bed using the casters 40 at the bottom of the base frame 1. The brake device of the casters 40 is locked to ensure stability. At this time, the three sets of electric telescopic rods 2 are in an initial inactive state, the fixed bed board 5 and the movable bed board 6 are in a horizontal state, and the support frame 13 is fixed to the fixed bed board 5 by the disassembly assembly of bolts 14 and nuts 15. All restraint components are released, and the soft pads 20 and other soft structures on its surface conform to the physiological curvature of the human body, providing initial support for the patient. The lift / lower switch is activated, and the three sets of electric telescopic rods 2 are activated and raised and lowered synchronously, adjusting the device to a plane with the same height as the target bed. The lift / lower switch is released, and the three sets of electric telescopic rods 2 remain locked in their current state. Medical staff lay out a transfer mat between the two beds and push the patient to move horizontally onto the fixed bed board 5 and the movable bed board 6, so that the patient's back is against the support frame 13, and the body position is adjusted to a comfortable lying position.

[0089] During the fixation phase, restraint components one and two work together: restraint strap one 16 wraps around the patient's shoulders and is fastened to restraint strap two 18 on the chest via buckle 17, achieving dual fixation of the chest and shoulders. The adjustable buckle 17 adapts to patients of different body types. Restraint strap three 19 wraps around and fastens around the waist and hips, ensuring a tight fit between the waist and hips and the support frame 13, preventing slippage during changes in body position. The patient's legs are placed on the leg frame 27, where the Velcro fasteners on the top of the leg frame 27 (one 28 and two 29) secure the thighs and calves respectively, making operation convenient and the tightness controllable. The feet are secured by elastic bands on the foot frame 30, and with the rotating structure of the connecting plate four 26, the feet are ensured to be placed naturally. The L-shaped frame 22 of the support component can be adjusted in angle and extended / retracted via rotating block 21, encircling the patient's chest from under the armpits to provide auxiliary support for the patient's upper limbs, further enhancing fixation stability.

[0090] After confirming that the patient's body is properly secured, activate the standing switch. The three sets of electric telescopic rods 2 work in concert: the three sets of electric telescopic rods 2 first raise and lower synchronously to lift the entire device to a suitable height. Then, the two middle electric telescopic rods, acting as support rods at the center of rotation, remain locked. The electric telescopic rods on the head side and foot side rotate relative to each other and extend and retract simultaneously, causing the entire device to rise headfirst and lower feetmost until the standing action is completed. After the standing action is completed, the three sets of electric telescopic rods remain locked in their current state.

[0091] At this time, medical staff can release the brake of the universal wheel 40 and push the device flexibly by the handle 4, so that the patient can temporarily leave the ward environment and go outdoors for training or socializing.

[0092] When the patient needs to perform leg training in an upright position, the bed separation switch is activated: Motor 9 on the guide plate 8 at the bottom of the movable bed board 6 is activated, driving gear 10 to rotate. Gear 10 meshes with rack 11 on support plate 7, causing the movable bed board 6 to move backward along the slide groove 12 on the inner side of support plate 7. Support plate 7 serves as the support frame for movable bed board 6, and slide groove 12 limits its movement path, ensuring stable translation. When movable bed board 6 moves backward until leg frame 27 and foot frame 30 are no longer supported, motor 9 continues to drive, and movable bed board 6 moves upward along slide groove 12 until it completely avoids the range of leg movement, at which point motor 9 shuts off. At this time, leg frame 27 and foot frame 30 are suspended in the air, providing unobstructed space for leg training and solving the defect of "limited leg movement" in existing integrated bed boards.

[0093] At this point, the corresponding leg training switch is activated, controlling motor 36 and electromagnetic clutch 39 to work alternately to complete the corresponding training for the patient's left and right legs. After the training is completed, pressing the end training switch will return motor 36 and electromagnetic clutch 39 to their initial state, and the patient's legs will return to an upright position.

[0094] After the patient is pushed back to the ward and placed next to the target bed, the casters 40 are secured, and the bed restoration switch is activated: motor 9 is started in reverse, and the movable bed board 6 moves down and then forward along the slide rail 12, resetting to align with the fixed bed board 5; the electric telescopic rod 2 is unlocked and rotates in the reverse direction, driving the rotating frame 3 to rotate counterclockwise to a horizontal position and lower to the initial height, which is the initial height of the three sets of electric telescopic rods 2. If necessary, the height of the device can be readjusted using the lifting switch to match the bed height.

[0095] The patient's foot elastic band, leg fixation straps 28 and 29, waist and hip restraint strap 3 19, and chest restraint strap 16 and restraint strap 2 18 are untied in sequence. The patient can then be transferred back to the target bed via the easy transfer method. If the device needs to be moved, the medical staff can hold the handle 4 at the front end of the rotating frame 3, unlock the brake of the universal wheel 40, push the device to the target position, and then lock it again. The operation is convenient and labor-saving.

[0096] Precautions for operation of this invention: The leg lifting angle and speed are controlled by the output speed of motor 36. The maximum lifting angle of the thigh is 90 degrees and the maximum lifting angle of the calf is 90 degrees. During the lifting process, the magnetic attraction state of the electromagnetic clutch 39 must strictly correspond to the target leg to avoid misoperation.

[0097] Before resetting the movable bed board 6, it is necessary to ensure that the leg frame 27 is in an upright position and aligned with the movable support groove of the movable bed board 6 to prevent collision; during the process of leveling the rotating frame 3, the extension and retraction speed of the electric telescopic rod 2 should be reduced slowly to avoid discomfort to the patient due to changes in body position;

[0098] When moving the device, first confirm that the brake device of the caster wheel 40 is in the unlocked state. After moving to the target position, immediately lock the brake to prevent the device from sliding.

[0099] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
