Description

Technical Field

[0001] This invention belongs to the field of nursing assistive equipment technology, specifically relating to an assistive standing and movement device. Background Technology

[0002] Patients typically require bed rest after surgery or when their condition is severe. However, prolonged bed rest can slow blood flow throughout the body, leading to pressure sores on the buttocks and a decreased metabolic rate, affecting digestion and nutrient absorption, thus hindering recovery. Furthermore, slow blood flow in the lower limbs can cause insufficient venous return, resulting in edema and, in severe cases, thrombosis. Therefore, once muscle strength has recovered, especially in the lower limbs where basic standing and walking are possible, patients should be encouraged to get out of bed and begin moving around, such as walking slowly while holding onto railings. This promotes blood circulation, strengthens muscles, and improves joint mobility, thereby aiding recovery.

[0003] However, clinical observations have revealed that although patients may have regained some muscle strength, stiffness and weakness in their lower back muscles during lying down make it difficult for them to get out of bed. Caregivers typically need to support their upper body and slowly roll them up. For patients just beginning to move around, due to their overall weakness, movements should be frequent and short in duration. While activity helps the body recover, it's also important to avoid prolonged activity that could lead to fatigue. Each time a patient gets out of bed, they require assistance from caregivers, increasing the workload for caregivers. This is especially true for heavier patients, who may require multiple caregivers to assist them, making it particularly difficult for them to get out of bed.

[0004] Currently, to address the difficulty patients have in getting out of bed, the common methods are fixing cloth ropes to the armrests on both sides of the bed or using beds with built-in lifting assist functions. With cloth ropes fixed to the armrests, patients pull on the ropes with both hands to lift their upper body off the bed. Beds with lifting assist functions use a flap located on the side of the patient's upper body that slowly rotates upwards to lift the upper body. However, when pulling on the cloth ropes to get up, patients need to continuously use their arms to lift their upper body. If the patient's arms lose strength, the rope may slip, causing patients to be afraid to use this method. In severe cases, it can even lead to the patient falling off the bed, making cloth rope-assisted lifting unsafe. Furthermore, because of the bedding on the bed, the maximum upward rotation angle of the lifting flap is only 60°~70°, making it inconvenient for patients to use, still requiring caregivers to assist or pull on the cloth ropes to fully lift the upper body.

[0005] In conclusion, existing methods for assisting patients to get out of bed have certain shortcomings, leading to patients' reluctance to get out of bed and move around, which is not conducive to their physical recovery. Summary of the Invention

[0006] In view of this, the present invention provides an assistive device for getting up and moving around, in order to overcome the shortcomings of the prior art.

[0019] This invention provides an auxiliary device for getting up, which is described below in conjunction with... Figures 1 to 10 The present invention is illustrated by the structural diagram shown below.

[0020] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the technical solution of this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0021] Reference Figure 1 As shown, Figure 1 This is a front view of the assisted standing exercise device of this embodiment. An assisted standing exercise device includes: a housing 1 and a standing assembly disposed on the housing 1. The housing 1 is vertically arranged on one side of the bed. The standing assembly includes: an arc-shaped slide rail 2 fixedly disposed on the side wall of the housing 1 opposite to the bed; a first slider 4 slidably disposed on the arc-shaped slide rail 2; one end of a first connecting rod 3 disposed on the first slider 4; the first connecting rod 3 is perpendicular to the side wall; two L-shaped hooks 5 are respectively disposed on the first connecting rod 3 for hooking the patient's shoulders from under the armpits; a drive mechanism is disposed in the housing 1, connected to the first slider 4 and electrically connected to a controller disposed on the outer wall of the housing 1; the user starts the drive mechanism through the controller to drive the first slider 4 to move upward along the arc-shaped slide rail 2, so that the first connecting rod 3 uses the L-shaped hooks 5 to help the patient's upper body stand up.

[0022] The assisted sitting-up device in this embodiment vertically positions the housing 1 on one side of the bed and integrates a linkage sitting-up mechanism consisting of an arc-shaped slide rail 2, a first slider 3, a first connecting rod 4, and an L-shaped hook 5. Combined with a built-in drive mechanism, it enables the patient's upper body to be smoothly raised along a natural turning trajectory. The core of this solution lies in using an arc-shaped path to guide the patient's upper body from a lying position to an upright position, improving the safety and comfort of the sitting-up process.

[0023] The housing 1, serving as the load-bearing foundation of the entire device, is vertically positioned on one side of the bed, specifically near the head of the bed to align with the patient's initial upper body position. Its shape can be rectangular or cylindrical, with internal space to accommodate the drive mechanism. It is constructed entirely of metal or high-strength engineering plastics, possessing sufficient structural rigidity and anti-overturning capability.

[0024] The curved slide rail 2 is located on the side of the housing 1 opposite the bed, specifically in the top corner area of ​​the housing 1 near the head of the bed. This arrangement ensures that the initial end of the curved slide rail 2 is perpendicular to the bed surface, allowing force to be applied upwards from a position close to the patient. Its end extends towards the foot of the bed, nearly parallel to the length of the bed, and may also have a horizontal section tangent to the curved slide rail 2, allowing the patient to move towards the edge of the bed after turning over, facilitating a smooth transition to the ground. The radius of curvature of the curved slide rail 2 can be set according to ergonomic data, ensuring its trajectory conforms to the natural rotation center of the upper body from supine to sitting. The curved slide rail 2 can be fixed to the housing 1 by embedding, with its outer side flush with the outer wall of the housing 1.

[0025] The first slider 3 is slidably mounted on the arc-shaped slide rail 2, serving as a key intermediate component for power transmission. An arc-shaped guide rod 23 is inserted through the interior of the arc-shaped slide rail 2 along its circumference. The arc-shaped guide rod 23 is coaxial with the center line of the arc-shaped slide rail 2. Both ends of the arc-shaped guide rod 23 are fixedly connected to the inner wall of the arc-shaped slide rail 2. The arc-shaped guide rod 23 passes through the first slider 3 and is slidably connected to it. The first slider 3 can move smoothly along the arc-shaped path under the drive of external force.

[0026] The first connecting rod 4 is horizontally positioned on the side of the first slider 3 closest to the bed, with one end rigidly connected to the first slider 3 and moving synchronously with it. This rod is straight and spans across the patient's torso, used to transmit the lifting force from the first slider 3.

[0027] Specifically, a connecting seat 32 is fixedly provided on the side of the first slider 3 away from the arc-shaped slide rail 2. One end of the connecting seat 32 is vertically fixedly connected to the first slider 3. An electric telescopic rod 33 is provided on the side of the connecting seat 32 away from the central axis of the arc-shaped slide rail 2. One end of the electric telescopic rod 33 is vertically fixedly connected to the connecting seat 32, and the other end is vertically fixedly connected to the first connecting rod 4. Through the connecting seat 32 and the electric telescopic rod 33, the position of the first connecting rod 4 can be flexibly adjusted according to the distance between the patient's waist and shoulder, so that the patient can turn over and get up with the waist as the axis, which is convenient for patients of different body types and further improves the flexibility of use.

[0028] Two L-shaped hooks 5 are vertically mounted on the first connecting rod 4 to correspond to the patient's shoulders. Each L-shaped hook 5 includes a vertical section and a horizontal section. The vertical section connects to the first connecting rod 4, while the horizontal section extends forward towards the head of the bed. The horizontal sections of both hooks are parallel to each other, forming a symmetrical clamping structure. Before the device is activated, the patient can place their armpits above the horizontal section. As the first connecting rod 4 rises, the L-shaped hooks 5 lift the shoulders from under the armpits, providing stable support. This design avoids the problems of pressure from traditional straps or instability when holding on, making it particularly suitable for users with weaker upper limb strength.

[0029] The drive mechanism is located inside the housing 1, and its output end is connected to the first slider 3, used to drive it to reciprocate along the arc-shaped slide rail 2. This drive mechanism can take various forms, such as a motor-gear-rack combination, an electric actuator with a guide mechanism, or a hydraulic / pneumatic system. For example, refer to... Figure 7 , Figure 7 This is an enlarged schematic diagram of point D of the assisted standing movement device in this embodiment. The driving mechanism in this embodiment includes: an arc-shaped plate 24, an arc-shaped rack 25, a first rotary power unit 27, and a gear 28. The arc-shaped plate 24 is fixed on the side of the arc-shaped slide rail 2 away from the first slider 3. The arc-shaped plate 24 is coaxial with the center line of the arc-shaped slide rail 2. An arc-shaped rack 25 is fixed on the outer side of the arc-shaped plate 24 and is coaxial with its center line. A first arc-shaped through groove 21 is opened at the bottom of the arc-shaped slide rail 2. A gear 28 is fixed on the side of the first slider 3 near the first arc-shaped through groove 21. The first rotary power unit 27 has its output shaft passing through the first arc-shaped through groove 21 and fitted with a gear 28. The gear 28 meshes with the arc-shaped rack 25. The first rotary power unit 27 is electrically connected to the controller. Through the cooperation of the arc-shaped plate 24, the arc-shaped rack 25, the first rotary power unit 27, and the gear 28, the first rotary power unit 27 can drive the gear 28 to rotate, causing the gear 28 to move along the arc-shaped rack 25, thereby driving the first slider 3 to move on the arc-shaped slide rail 2. The first rotary power unit 27 is powered by an external power source and is electrically connected to the control system, supporting remote start / stop, speed adjustment, and travel limit functions to ensure smooth and adjustable movement.

[0030] In this embodiment, the controller can take the form of a control handle. The control handle is connected to the first rotary power unit 27 via a signal line. During use, the control handle can be operated by the patient or by a nursing staff.

[0031] The aforementioned components work in concert: when the drive mechanism is activated, it drives the first slider 3 to move slowly from bottom to top along the arc-shaped slide rail 2, thereby pulling the first connecting rod 4 and its L-shaped hook 5 upwards simultaneously. Because the geometric path design of the arc-shaped slide rail 2 conforms to the rotation law of the human spine, the patient's upper body will gradually rise along the arc trajectory with the waist as an approximate fulcrum, ultimately reaching a sitting angle close to 90°. During this process, the shoulders are effectively supported by the L-shaped hook 5 to prevent slippage.

[0032] The above embodiments achieve a safe, stable, and fully automatic assistive function for bedridden patients to get up. By employing a power guidance mechanism based on an arc-shaped trajectory, it overcomes the technical limitations of traditional planar lifting devices that suffer from insufficient getting-up angles, enabling patients to achieve a more thorough posture transition. The L-shaped hooks directly act on the shoulder and armpit areas, providing reliable mechanical support points and significantly reducing the risk of dislocation due to limb weakness during getting up. The coordination between the drive mechanism and the slider-rail system ensures the continuity and controllability of the movements, improving the user experience. This device is particularly suitable for daily care scenarios in the postoperative recovery period, for the elderly and frail, or for individuals with neuromuscular dysfunction, reducing the workload of caregivers and enhancing patients' independent living abilities and rehabilitation motivation.

[0033] Specifically, the controller uses a knob switch on the handle, and nursing staff or patients can start the first rotary power unit 27 by turning the knob switch.

[0034] Reference Figure 2 As shown, Figure 2 This is a top view of the assistive standing exercise device in this embodiment. As a further optimization, in this embodiment, a second connecting rod 6 is provided on the side wall of the box 1 opposite to the bed, and is located on the side of the box 1 near the foot of the bed. The second connecting rod 6 is parallel to the first connecting rod 3. Two lower limb levers 7 are vertically arranged on the lower side of the second connecting rod 6 and are perpendicular to each other. The two lower limb levers 7 are located on the outside of the patient's legs to clamp them. A support is vertically arranged at the bottom of the box 1. The box 1 is rotatably connected to the support around its vertical center line, so that the patient's upper body shifts towards the middle of the bed when standing up and the lower limb levers 7 drive the patient's legs to shift towards the outside of the bed.

[0035] This embodiment introduces a second connecting rod 6, a lower limb lever 7, and a rotating connection structure between the housing 1 and the support. Building upon the existing upper body assistive turning function, it achieves coordinated guidance of the patient's lower body posture. The entire system constitutes a spatial linkage-based standing control mechanism, enabling the upper body and lower limbs to synchronously adjust directional displacement during the transition from a lying to a sitting position, thereby improving the coordination and safety of the standing motion.

[0036] The second connecting rod 6 is horizontally positioned on the side of the housing 1 closest to the first slider 3, diagonally opposite to the arc-shaped slide rail 2, with its centerline parallel to the centerline of the arc-shaped slide rail 2. This diagonal arrangement ensures that when the housing 1 rotates, the second connecting rod 6 can drive the connected lower limb lever 7 to provide lateral support to the patient's leg. The second connecting rod 6 can be made of high-strength metal materials such as aluminum alloy or stainless steel, possessing sufficient rigidity to withstand the thrust load during transmission.

[0037] Two lower limb paddles 7 are vertically arranged on the lower side of the second connecting rod 6, and are perpendicularly connected to the second connecting rod 6 to form a T-shaped or inverted T-shaped connection structure. The lower limb paddles 7 extend vertically and are located on the outer sides of the patient's legs to apply directional abduction force during movement. The installation distance between the two lower limb paddles 7 can be adjusted according to the average adult leg width, usually set between 400mm and 500mm to meet the needs of most users. As an optional embodiment, the lower limb paddles 7 can also be connected to the second connecting rod 6 by sliding, and the distance can be adjusted with the locking mechanism to enhance the versatility of the device.

[0038] The lower limb paddle 7 is vertically positioned and designed to gently push against the patient's lower leg from the outside. Its shape can be straight or slightly curved to conform to the contours of the leg and reduce local pressure. Engineering plastics such as ABS or nylon can be used, with a soft cushioning layer such as silicone or sponge covering the surface to improve comfort.

[0039] The bottom of the housing 1 is equipped with a support, through which housing 1 can rotate relative to its own vertical centerline. The support serves as the supporting foundation, while housing 1 is rotatably connected to the support via bearings, slewing bearings, or bushing structures, allowing for rotational movement around the vertical axis at a certain angle. The typical rotation angle range is 0° to 90°, sufficient to complete the attitude transformation from initially parallel to the long side of the bed to ultimately perpendicular to the bed surface. This rotatable connection structure is the key load-bearing component for realizing the overall rotational movement, and must possess good coaxiality and low friction characteristics to ensure smooth movement and repeatable positioning accuracy.

[0040] When the drive mechanism moves the first slider 3 upward along the arc-shaped slide rail 2, the entire housing 1 rotates. Since the second connecting rod 6 is diagonally arranged with the arc-shaped slide rail 2, it generates a horizontal displacement component pointing outwards as it rotates with the housing 1. This displacement is transmitted to the patient's legs through the lower limb lever 7, achieving passive abduction guidance. Simultaneously, the first connecting rod 4 and its L-shaped hook 5 also rotate with the housing and shift towards the center of the bed, gradually moving the patient's upper body towards the center of the bed, thus avoiding the risk of the body slipping off the edge of the bed during the process of getting up.

[0041] This embodiment achieves coordinated spatial control of the upper and lower body during the patient's ascent. This is achieved by incorporating a second connecting rod 6 diagonally arranged to the arc-shaped slide rail 2 and a lower limb lever 7 vertically connected to it, along with a rotatably connected support structure at the bottom of the housing 1. During the assistive ascent process, rotating the housing 1 not only allows the patient's upper body to shift towards the center of the bed when rising, but also utilizes the lower limb lever 7 to shift the patient's legs towards the outside of the bed.

[0042] Reference Figure 3 As shown, Figure 3This is a side view of the assistive standing exercise device in this embodiment. As a further optimization, in this embodiment, a linear guide rail 8 is horizontally fixed on the side wall of the box 1 opposite to the bed. The linear guide rail 8 is parallel to the side wall. A second slider 9 is slidably mounted on the linear guide rail 8. One end of the second connecting rod 6 is fixedly connected to the second slider 9. A rope 10 is connected between the second connecting rod 6 and the bracket. When the linear guide rail 8 rotates with the box 1, the second slider 9 moves toward one end of the linear guide rail 8.

[0043] This embodiment provides a structural scheme for synchronously adjusting the position of the second connecting rod during the rotation of the box. By setting the linear guide rail 8 and the second slider 9 to form a sliding guide pair, and combining it with the rope 10, the second connecting rod 6 can realize that the lower limb lever 7 can automatically move along the patient's lower limb towards the waist side when the box 1 rotates, so as to adapt to changes in spatial displacement, thereby ensuring that the lower limb lever applies a stable and continuous guiding force to the patient's lower limb.

[0044] The linear guide rail 8 serves as a guiding element, providing a precise linear sliding path for the second slider 9. The cross-sectional shape of the linear guide rail 8 can be rectangular, dovetail-shaped, or cylindrical, and it works in conjunction with the corresponding slider structure to achieve low-friction sliding.

[0045] The second slider 9 is a movable component mounted on the linear guide rail 8. It contains ball bearings or sliding bearings to reduce frictional resistance and improve motion smoothness. The second slider 9 can slide freely along the linear guide rail 8 under external force, possessing a certain load-bearing capacity and resistance to eccentric loads. As the connecting node of the second connecting rod 6, the second slider 9 transmits motion and force. Its structural form can be selected from standard linear module sliders or customized sliding sleeve structures depending on the actual load conditions.

[0046] One end of the second connecting rod 6 is fixedly connected to the second slider 9. This connection can be achieved by bolting, welding or interference fit, etc., to ensure a firm and reliable connection.

[0047] A rope 10 connects the second connecting rod 6 to the support. This rope 10 can be made of synthetic fiber materials such as polyamide, polyester, or braided tape, possessing a certain tensile strength. One end of the rope 10 is connected to the side of the second connecting rod 6 near the second slider 9 or directly to the second slider 9, while the other end is fixed to a specific anchor point on the support, located near the outer side of the rotation center of the housing 1. Since the support is a static foundation structure, and the second connecting rod 6 rotates with the housing 1, the spatial distance between them changes periodically during rotation. When the housing rotates from its initial position towards the bed width direction, the second connecting rod swings outward, increasing the linear distance between it and the support. The rope 10 pulls the second slider 9 or the second connecting rod 6, causing the second slider 9 to move along the linear guide rail 8.

[0048] As a further optimization, in this embodiment, the linear guide rail 8 is provided with an elastic damping element to drive the second slider 9 to move to the other end of the linear guide rail 8.

[0049] In this embodiment, an elastic damping element is provided on the linear guide rail 8 to provide directional restoring force to the second slider 9, so that it can automatically return to the position near the foot of the bed when it is not in operation or after the action is completed, and so that the second slider 9 remains stable when moving, thereby allowing the lower limb lever 7 to move at a uniform speed along the patient's lower limb towards the waist.

[0050] The elastic damping element can be a spring-damper combination structure, such as a compression coil spring and a hydraulic buffer arranged in parallel, or it can be a component made of an integral elastic damping material, such as a rubber-metal composite bushing or a viscoelastic polymer component. One end of the elastic damping element is fixed to the end region of the linear guide 8 near the headstock, and the other end is connected to the second slider 9 or a transmission component linked to it. Thus, after the rotation of the housing stops, a force pointing towards the tailstock is continuously applied, ensuring that the second slider 9 slides along the linear guide 8 to the end of its stroke and remains stably positioned.

[0051] The elastic damping element not only provides static reset capability but also has dynamic buffering characteristics. When the housing 1 drives the linear guide 8 to rotate, the second slider 9 is pulled towards the head of the bed by the rope 10, overcoming the resistance of the elastic damping element.

[0052] This embodiment achieves a solution by incorporating an elastic damping element with directional reset capability and buffering function on the linear guide rail 8. This allows the second slider 9 to reliably return to a preset position near the foot of the bed after each operation, resolving the initial position offset problem caused by the lack of an active return mechanism in passive transmission systems. Simultaneously, the elastic damping element ensures the stability of the second slider 9 during movement, improving the stability and comfort of the device's operation and preventing swaying from affecting the patient's user experience.

Figure 5This is a BB cross-sectional view of the assistive standing exercise device in this embodiment. As a further optimization, in this embodiment, a rotating shaft 11 is horizontally provided inside the housing 1 and is rotatably connected to it. The rotating shaft 11 is parallel to the first connecting rod 3. A worm gear sleeve 12 is fitted on the rotating shaft 11. An annular toothed ring 13 is horizontally fixed at the top of the bracket and is coaxial with the vertical center line of the housing 1. The bottom of the housing 1 is fitted through the annular toothed ring 13 and is rotatably connected to it. The teeth of the annular toothed ring 13 are located at its top and mesh with the worm gear sleeve 12. The rotating shaft 11 is connected to the first slider 4 through an elastic telescopic rod 14. When the first slider 4 moves on the arc-shaped slide rail 2, it drives the rotating shaft 11 to rotate around its circumference.

[0054] In this embodiment, by setting up a transmission structure of rotating shaft 11, worm gear sleeve 12, and ring gear ring 13, and combining the linkage between elastic telescopic rod 14 and first slider 3, a technical path is achieved to drive the overall rotation of the box body by utilizing the arc-shaped motion of the first slider 3 during the patient's ascent. The rotating shaft 11 is a rigid rod-shaped component, horizontally positioned inside the box body 1, and connected to the box body 1 via bearings or bushings to ensure its free rotation around its own axis. The rotating shaft 11 is arranged diagonally to the arc-shaped slide rail 2, and its extension direction is parallel to the centerline of the arc-shaped slide rail 2. This spatial arrangement allows the first slider 3 to apply torque to the rotating shaft 11 at a specific angle via the elastic telescopic rod 14 when moving along the arc-shaped trajectory, thereby stimulating its circumferential rotational motion. The rotating shaft 11 drives the worm gear sleeve 12 to rotate on the ring gear ring 13, enabling the patient's upper body to shift towards the center of the bed when the patient rises.

[0055] The worm sleeve 12 is fixedly fitted around the outer circumference of the rotating shaft 11 and can rotate synchronously with the rotating shaft 11. Its shape is a cylindrical helical tooth structure, constituting the driving component in the worm gear transmission. The annular gear ring 13 is a ring-shaped gear structure, horizontally fixed to the top of the support, with its central axis coaxial with the vertical center line of the housing 1. The bottom of the housing 1 passes through the annular gear ring 13 and forms a rotational engagement with its outer side, for example, through a rolling bearing or sliding bearing to achieve a low-friction rotational connection. The teeth of the annular gear ring 13 are distributed on its top end face, facing upwards and meshing with the helical teeth of the worm sleeve 12, forming a worm-gear transmission pair. This transmission method has a one-way self-locking characteristic, meaning the worm can drive the gear ring to rotate, but the gear ring cannot drive the worm in the opposite direction, effectively preventing accidental rotation of the housing due to external disturbances or load changes, thus improving the safety and stability of the device operation.

[0056] The elastic telescopic rod 14, as a mechanical linkage element, is connected at both ends to the rotating shaft 11 and the first slider 3, respectively. Its structure can be a spring-type telescopic rod, a hydraulically damped telescopic rod, or a guide sleeve structure with built-in elastic elements, allowing it to freely extend and retract within a certain stroke range and provide restoring force. When the first slider 3 slides along the arc-shaped slide rail 2, it pulls one end of the elastic telescopic rod 14, causing it to move accordingly. Since the other end of the rotating shaft 11 is constrained within the housing 1 and can only rotate, the pulling force, under the oblique action in space, decomposes into a tangential component, forming a rotational torque acting on the rotating shaft 11, which in turn drives the worm sleeve 12 to rotate. As the worm sleeve 12 rotates, its meshing relationship with the annular gear ring 13 pushes the housing 1 to undergo controllable deflection around the vertical centerline.

[0057] Specifically, the inner side of the arc-shaped slide rail 2 is provided with a second arc-shaped through groove 22 along its circumference. The end of the elastic telescopic rod 14 away from the rotating shaft 11 passes through the second arc-shaped through groove 22 and is connected to the first slider 3. The teeth on the annular gear ring 13 can also be set only on the side close to the worm gear sleeve 12.

[0058] A clear mechanical transmission link is formed between the above-mentioned components: the arc-shaped upward motion of the first slider 3 is converted into the rotational input of the rotating shaft 11 through the elastic telescopic rod 14. The rotating shaft drives the worm gear sleeve 12 to rotate, and the worm gear sleeve drives the ring gear ring 13 to realize the overall deflection action of the housing 1. This linkage mechanism can complete the rotation function without the need for additional independent motors or control systems, making full use of the energy output of the original drive mechanism and improving the system integration and energy utilization efficiency.

[0059] This embodiment transforms the reciprocating motion of the first slider 3 along the arc-shaped slide rail 2 into a controllable rotational motion of the housing 1 around the vertical axis. Because the rotating shaft 11 and the arc-shaped slide rail 2 are arranged diagonally, the displacement vector generated by the first slider 3 during its ascent can be effectively decomposed into the torque component driving the rotating shaft 11 to rotate. The elastic telescopic rod 14 not only transmits power but also absorbs minor deviations and impacts during the motion, ensuring smooth transmission. The meshing transmission between the worm gear sleeve 12 and the ring gear 13 efficiently transmits the rotational motion to the housing 1 and, with its self-locking characteristic, prevents reverse rotation, enhancing the structural reliability of the device under load.

[0060] Therefore, this structure achieves coordinated execution of the adduction movement of the patient's upper body and the guidance of the lower limbs to shift outward from the bed without adding an additional power source.

[0061] Reference Figure 6 , Figure 6This is a CC cross-sectional view of the assistive standing exercise device in this embodiment. The bracket in the above embodiment includes a base 41 and telescopic columns 42. The base 41 is horizontally arranged directly below the box 1. Multiple telescopic columns 42 are vertically fixed around the base 41 at equal intervals with the vertical center line of the box 1 as the center. The upper end of the telescopic column 42 is fixedly connected to the bottom of the annular toothed ring 13.

[0062] In addition, a screw 71 is vertically fixed on the base 41. The screw 71 is coaxial with the vertical center line of the housing 1. The screw 71 extends into the housing 1 and is fitted with an internally threaded tube 72. The internally threaded tube 72 is threadedly connected to the screw 71. A second rotary power unit 73 is fixedly installed on the top inner side of the housing 1. The output shaft of the second rotary power unit 73 is fixedly connected to the top of the internally threaded tube 72. By using the screw 71, the internally threaded tube 72 and the second rotary power unit 73 together, the height of the housing 1 can be flexibly adjusted to facilitate use with beds of different heights. The second rotary power unit 73 is electrically connected to the controller, and the controller controls the first stepper motor according to the height of the bed.

[0063] As a further optimization, in this embodiment, two second connecting sleeves 15 are coaxially sleeved on the second connecting rod 6. The second connecting sleeves 15 are slidably connected to the second connecting rod 6 along its length. The top of the lower limb lever 7 is fixedly connected to the second connecting sleeves 15. A first elastic traction member is provided between the ends of the two second connecting sleeves 15 that are far apart from each other and the end of the second connecting rod 6, so as to drive the two second connecting sleeves 15 to move towards the side that is closer to each other.

[0064] This embodiment provides a structure for adaptive adjustment of the clamping component for the patient's lower limbs. By combining a sliding connection structure with an elastic element, the lower limb lever 7 can automatically adjust its position according to the actual distance on the outer sides of the patient's legs, thereby improving the device's adaptability to different patients.

[0065] The second connecting rod 6, serving as a component of the second connecting sleeve 15, can have a circular, square, or polygonal cross-section, with a circular shape preferred to facilitate smooth sliding of the second connecting sleeve 15. The second connecting sleeve 15 is a hollow cylindrical structure, with its inner diameter matching the outer diameter of the second connecting rod 6 for a sliding fit. Each second connecting sleeve 15 can slide freely along the length of the second connecting rod 6, thereby changing the distance between the two lower limb levers 7. The second connecting sleeve 15 is made of engineering plastic or lightweight metal, balancing wear resistance and low friction. The lower limb levers 7 are vertically positioned below the second connecting sleeves 15, and the outer wall of the second connecting sleeve 15 has a connecting flange or threaded interface for fixed connection with the top of the lower limb levers 7. The two lower limb levers are arranged in pairs on the outer sides of the patient's legs to apply guiding force to the legs during standing. The first elastic traction element is located between the ends of the two second connecting sleeves 15 that are far apart from each other and the ends of the second connecting rod 6, with one on each side for a total of two, symmetrically distributed. The first elastic traction component can be an elastic element with energy storage and release functions, such as a tension spring, a rubber elastomer, a pneumatic damping unit, or a coil spring mechanism with preload. One end of it is connected to the second connecting sleeve 15, and the other end is connected to the end of the second connecting rod 6, generating an inward driving force. When the patient's legs are placed between the two lower limb levers 7, the legs spread outward, causing the second connecting sleeve 15 to slide on the second connecting rod 6, overcoming the elastic force of the first elastic traction component and automatically clamping the patient's legs. In addition, limiting structures, such as axial bosses or retaining rings, can be provided at both ends of the second connecting rod 6 to prevent the second connecting sleeve 15 from detaching from the rod during sliding. In this embodiment, the lower limb levers 7 can be closely fitted to both sides of the patient's legs during the assisted standing process.

[0066] In this embodiment, the second connecting rod 6 can be a telescopic rod. While adjusting the position of the lower limb lever 7 through the second connecting sleeve 15, the second connecting rod 6 can also be shortened to reduce the space occupied when the device is not in use.

[0067] As a further optimization, in this embodiment, the cross-section of the lower limb paddle 7 is arc-shaped, and the center line of the arc is parallel to the vertical center line of the box 1. The center lines of the two lower limb paddles 7 are located on opposite sides of each other.

[0068] This embodiment sets the lower limb paddles in an arc shape and keeps their geometric center line parallel to the vertical center line of the housing. At the same time, the center lines of the two lower limb paddles are arranged opposite to each other, so that when the second connecting rod 6 drives the lower limb paddles 7 to move along the patient's lower limb towards the waist, the distance between the two lower limb paddles 7 automatically increases.

[0069] The lower limb paddle 7 is made of a material with a certain degree of rigidity and elasticity, such as engineering plastics or lightweight metal alloys. The surface can be covered with a soft cushioning layer such as silicone or polyurethane foam to reduce local pressure and prevent skin abrasions.

[0070] As an alternative implementation, the lower limb paddle 7 can also be designed as a variable curvature structure. The curvature of the lower limb paddle 7 is smaller on the side closer to the second connecting rod 6, and the curvature gradually increases on both sides of the second connecting rod 6. While ensuring the stability of clamping the patient's leg, the lower limb paddle 7 can move along the patient's leg to adapt to the physiological changes of the patient's leg from thin to thick.

[0071] As a further optimization, in this embodiment, two first connecting sleeves 17 are coaxially sleeved on the first connecting rod 3. The first connecting sleeves 17 are slidably connected to the first connecting rod 3 along its length direction. The first connecting sleeves 17 are detachably connected to the first connecting rod 3 by fasteners. The vertical end of the L-shaped claw 5 is fixedly connected to the first connecting sleeves 17.

[0072] This embodiment provides an auxiliary clamping structure with adjustable lateral position for the patient's shoulder. By modularly designing the connecting components on the first connecting rod 4, it can adapt to patients of different body types. The first connecting rod 4 serves as a lateral support base, and its cross-section can be circular, square, or polygonal, and can be selected as a cylindrical structure to facilitate the sliding of the first connecting sleeve 17 on it and achieve flexible configuration of circumferential limiting or no limiting.

[0073] The first connecting sleeve 17 is a hollow tubular structure with an inner diameter matching the outer diameter of the first connecting rod 4. It allows for free axial sliding through a clearance fit or a transition fit. Two first connecting sleeves 17 are respectively mounted on the first connecting rod 4, and their spacing can be adjusted as needed to change the lateral span between the L-shaped claws 5 on both sides. This adjustment process allows for initial positioning without tools, followed by locking using fasteners.

[0074] The first connecting sleeve 17 is fixed relative to the first connecting rod 4 using fasteners, including but not limited to: locking screws, clamping clamps, elastic buckles, or quick-release pin mechanisms. For example, in one optional embodiment, the surface of the first connecting rod 4 has multiple equidistantly distributed positioning holes along its length, and the first connecting sleeve 17 has corresponding through holes and elastic spring pin assemblies. When slid to the target position, the spring pin automatically springs into the positioning holes for quick fixing. In another embodiment, the fastener is a side-locking hexagonal socket head cap screw, which, after tightening, abuts against the surface of the first connecting rod 4 to generate friction, achieving stepless adjustment and reliable locking. All of the above fastening methods can achieve detachable fixed connections, meeting the needs of frequent adjustments and subsequent maintenance in clinical use.

[0075] The vertical end of the L-shaped hook 5 is fixedly connected to the first connecting sleeve 17, and the connection method can be a welded threaded connection. This connection structure allows the L-shaped hook 5 to not only be flexibly adjusted in terms of lateral spacing, but also to be replaced with different types or sizes of hooks as needed, such as special models suitable for children, thin patients, or those in a protective state after shoulder surgery.

[0076] The components work together through sliding fit and mechanical locking. The first connecting sleeve 17 serves as an intermediate connecting unit, which not only serves as the mounting base for the L-shaped hook 5, but also provides it with adjustable position on the first connecting rod 4. The fastener provides stable fixed support after adjustment, preventing relative displacement due to vibration or force changes during the process of the drive mechanism lifting the patient, thus ensuring clamping stability and safety.

[0077] This embodiment enables manual adjustment of the relative positions of the two first connecting sleeves 17 on the first connecting rod 4 according to the differences in shoulder width among different patients during the assisted standing process. This adjustment, in turn, adjusts the lateral spacing of the L-shaped hooks 5, allowing the hooks on both sides to accurately fit the patient's armpit area, achieving stable and comfortable clamping support. Due to the adoption of a sliding connection and detachable fastening structure, this design not only improves the ergonomic adaptability of the device but also enhances its safety and comfort during use.

[0078] Alternatively, the first connecting rod 4 can also be a telescopic rod. While adjusting the position of the L-shaped hook 5 through the first connecting sleeve 17, the first connecting rod 4 can also be shortened to reduce the space occupied when the device is not in use.

[0079] As a further optimization, in this embodiment, a clamping rod 18 is horizontally provided above the horizontal section of the L-shaped claw 5. The clamping rod 18 is parallel to the horizontal section of the L-shaped claw 5. The clamping rod 18 is slidably connected to the L-shaped claw 5 in the vertical direction. The L-shaped claw 5 is provided with a second elastic traction member to drive the clamping rod 18 to move towards the side closer to the horizontal section of the L-shaped claw 5.

[0080] This embodiment uses a vertically sliding clamping rod 18 above the horizontal section of the L-shaped hook 5, and a second elastic traction member to apply a downward pre-tightening force, forming a bidirectional clamping structure for the patient's shoulders. This design upgrades the original fixation method that relied solely on the L-shaped hook to hook the shoulder on one side to a U-shaped clamping mechanism with adaptive clamping capability, significantly improving the stability and safety of upper body support during standing up without increasing operational complexity.

[0081] The L-shaped claw 5 includes a vertical section and a horizontal section. The horizontal section supports the patient's axillary region from below, forming the bottom boundary of the clamping mechanism. The clamping rod 18 is horizontally positioned directly above this horizontal section, with the two sections parallel and spaced a certain distance apart, thus creating a space in the vertical direction to accommodate the shoulder. The clamping rod 18 moves vertically relative to the L-shaped claw 5 via a sliding connection structure.

[0082] Specifically, the horizontal section of the L-shaped hook 5 and the clamping rod 18 form a U-shaped clamping clamp. A groove is provided along the length of the vertical section of the L-shaped support arm 81. The clamping rod 18 passes horizontally through the groove. A guide rod 51 is vertically provided in the groove. The two ends of the guide rod 51 are fixedly connected to the inner wall of the groove. The guide rod 51 passes through the clamping rod 18 and is slidably connected to it. The second elastic traction member is sleeved on the guide rod 51. Through the cooperation of the L-shaped hook 5, the clamping rod 18, the guide rod 51 and the second elastic traction member, the patient's shoulders can be automatically clamped from under the armpits to prevent slippage when standing up. After standing up, the horizontal section of the L-shaped hook 5 supports the patient's armpits upwards. The clamping rod 5 is then separated after the patient's condition stabilizes, further improving the safety of the standing assistance.

[0083] In addition, the horizontal section of the L-shaped claw 5 and the clamping rod 18 are arc-shaped, and the horizontal section of the L-shaped claw 5 and the side of the clamping rod 18 away from the vertical section of the L-shaped claw 5 are arc-shaped and offset towards each other, which further improves the stability of clamping the patient's shoulder.

[0084] The second elastic traction element is disposed on the L-shaped hook 5 and is used to provide an elastic pulling force that continuously moves the clamping rod 18 towards the horizontal section of the L-shaped hook 5. This second elastic traction element can be a common elastic element such as a coil spring, rubber spring, or spring sheet. One end is fixed to the upper structure of the L-shaped hook 5, and the other end is connected to the clamping rod 18 or its linkage component. The second elastic traction element always applies a downward force to the clamping rod 18, thereby enabling the clamping rod 18 to conform to or lightly press against the upper surface of the patient's shoulder, forming a stable upper and lower clamping effect.

[0085] As an optional implementation, a vertically arranged guide rod can be installed inside the chute, with both ends fixed to the inner wall of the chute. The clamping rod 18 is sleeved on the guide rod and slidably connected to it. The second elastic traction member is sleeved on the outside of the guide rod, with one end abutting against the upper surface of the clamping rod 18 and the other end abutting against the inner wall of the top of the chute, so as to achieve uniform force on the clamping rod 18. This structure helps to improve the smoothness of sliding and prevent the clamping rod 18 from deflecting or getting stuck.

[0086] As an alternative, the clamping rod 18 can also be raised and lowered in a controlled manner via a pneumatic or electric push rod. In this case, the function of the second elastic traction element is replaced by the actuator combined with sensor feedback control logic, which can dynamically adjust the clamping force according to the pressure detection results. This is suitable for intelligent nursing scenarios that require precise control of clamping force.

[0087] The horizontal section of the L-shaped hook 5 and the clamping rod 18 together form a U-shaped clamping clamp structure. The relative positional relationship between the two ensures that the patient's shoulder is restricted in vertical freedom of movement. When the patient adjusts their position so that their armpit enters the U-shaped space, the second elastic traction member drives the clamping rod 18 to move downward, completing the automatic locking action. When the device resets after the patient gets up, the clamping state can be released by manually lifting the clamping rod 18 or triggering the release mechanism, making it easy for the patient to get out.

[0088] This embodiment achieves flexible bidirectional clamping of the patient's shoulders. Due to the synergistic effect of the clamping rod 18 and the second elastic traction element, the original support structure relying on a single hook is transformed into a clamping system with active clamping capability, effectively solving the risk of shoulder slippage caused by sweating, muscle tension, or lack of coordination. The working principle of the assistive movement device of this invention is as follows: When a bedridden patient wants to get out of bed and move around, the controller activates the first rotary power unit 27. The first rotary power unit 27 drives the gear 28 to move downward along the arc-shaped rack 25, causing the first slider 3 to move downward along the arc-shaped slide rail 2. The first connecting rod 4 drives the two L-shaped hooks 5 to move downward along an arc trajectory. At the same time, the first slider 3 drives the rotating shaft 11 to rotate around its center line through the elastic telescopic rod 14. The worm sleeve 12 meshes with the ring gear ring 13, causing the worm sleeve 12 to rotate circumferentially along the ring gear ring 13, thereby driving the rotating shaft 11 and the housing 1 to rotate. This causes the first connecting rod 4 and the second connecting rod 6 to rotate from a state parallel to the length direction of the bed to a state parallel to the width direction of the bed 74, respectively. Figure 8 The diagram shows the first state of the assisted standing device of the present invention. The two L-shaped hooks 5 are positioned directly under the patient's armpits. The patient moves slightly towards the foot of the bed or is moved with the assistance of a caregiver. The patient's shoulders are gripped in a U-shaped clamp formed by the L-shaped hooks 5 and the clamping rod 18. The two lower limb levers 7 on the second connecting rod 6 are positioned on the outside of the patient's calves for clamping. The controller then activates the first rotating power unit 27, which drives the gear 28 to rotate in the opposite direction. This causes the first slider 3 to move upward along the arc-shaped slide rail 2, allowing the first connecting rod 4 to use the two L-shaped hooks 5 to lift the patient's upper body upward. Simultaneously, the first slider 3 uses the elastic telescopic rod 14 to drive the rotating shaft 11 and the worm gear sleeve 12 to rotate. The worm gear sleeve 12 meshes with the annular gear ring 13, causing the worm gear sleeve 12 to rotate in the opposite direction along the circumference of the annular gear ring 13. Figure 9 The diagram shows the second state of the assisted sitting-up device of the present invention. The housing 1 drives the first connecting rod 4 and the second connecting rod 6 to rotate from a state parallel to the width direction of the bed 74 to a state parallel to the length direction of the bed 74, enabling rotation when the patient's upper body is turned over. For example, if the device is located on the right side of the bed 74, when the patient turns over to sit up, the patient rotates counterclockwise from a top-down perspective. During the sitting-up process, the electric telescopic rod 33 shortens, causing the patient to move towards the edge of the bed. The second connecting rod 6 uses two lower limb levers 7 to simultaneously rotate the patient's lower legs towards the side of the bed closest to the device. As the second connecting rod 6 rotates, the rope 10 drives it along the linear guide rail 8. The device is moved so that the lower limb lever 7 gradually moves from the patient's lower leg to the thigh, thereby gradually rotating the patient's lower limbs away from the bed. When the patient finally sits up, they are positioned on the side of the bed 74 closest to the device, with their lower limbs hanging naturally to the ground. Once the patient feels stable, the L-shaped hook 5 is separated from the patient's shoulder, and the lower limb lever 7 is separated from the patient's legs. The device is then moved away from the bed 74 (moving wheels can be installed at the bottom of the device for nursing staff to move). Alternatively, the controller can be used to continue rotating the housing 1 counterclockwise (if a rotation of 180° or more is required, the horizontal extension length of the arc-shaped slide rail 2 near the top of the housing 1 needs to be increased). Figure 10 The diagram shown is a schematic of the third state of the assisted standing exercise device of the present invention, in which the patient stands up from a sitting position and gets off the ground to move around.

[0089] In addition, when the housing 1 in this device can be raised and lowered vertically along the annular gear ring 13, for example, by setting a vertical lifting mechanism between the annular gear ring 13 and the housing 1, so that the teeth of the annular gear ring 13 and the worm gear sleeve 12 can be separated, then after the patient has finished getting out of bed and is sitting on the bed, the above-mentioned state of the L-shaped hook 5 holding the patient's shoulder can be repeated. At this time, the first connecting rod 4 is parallel to the width direction of the bed, and the patient's legs are not held by the lower limb lever 7. The first rotating power unit 27 drives the first slider 3 to move downward along the arc-shaped slide rail 2. The housing 1 does not rotate. Using the first connecting rod 4 and the L-shaped hook 5, the patient is slowly pulled back onto the bed. The patient's legs can move onto the bed by themselves when lying down.

[0090] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
