A leg walking aid for rehabilitation care

Abstract

This invention relates to the field of rehabilitation nursing technology and discloses a leg-assisted walking device for rehabilitation nursing. The device includes an assistive walking support and positioning mechanism. At both ends of the top center of the assistive walking support and positioning mechanism, a first lifting mechanism, a first auxiliary bending mechanism, a second lifting mechanism, a second auxiliary bending mechanism, and a third lifting mechanism are sequentially fixedly connected. This invention integrates the first and second auxiliary bending mechanisms, which are driven by a first drive motor and a second drive motor, respectively, to rotate a first positioning gear and a second positioning gear. This, in turn, causes a second support frame and a fourth support frame to bend, simulating the natural bending movements of the human thigh and calf. This design allows patients to more accurately simulate a natural gait during rehabilitation training, effectively stimulating the joints and muscles of the legs to fully engage, and avoiding safety hazards and poor rehabilitation effects caused by the legs' inability to move synchronously with the device.

Description

Technical Field

[0001] This invention belongs to the field of rehabilitation nursing technology, and specifically relates to a leg-assisted walking device for rehabilitation nursing. Background Technology

[0002] Against the backdrop of a growing global population aging trend, persistently high rates of disease and injury, and a profound shift in rehabilitation medicine from the traditional "alternative care" model to "functional recovery," the market demand for leg assistive walking devices for rehabilitation care is showing a sustained growth trend. From a technical perspective, traditional assistive devices, such as crutches, walking frames, and paraplegic walking aids, provide fundamental support for mild lower limb dysfunction and early postoperative rehabilitation. These devices are widely used in various fields such as neurorehabilitation, orthopedic rehabilitation, geriatric care, and sports rehabilitation, effectively promoting patients' neurological function remodeling, muscle strength recovery, and improved self-care abilities.

[0003] In existing technologies, continuous rehabilitation care is essential to prevent leg muscle atrophy in severely injured patients and to stimulate their rehabilitation walking function. While commonly used leg-assisting walking devices provide strong body support during rehabilitation, there is a potential risk that the legs may not move synchronously with the device when the patient's leg mobility is weak. This could lead to dragging of the legs or twisting of the feet, causing safety hazards and failing to effectively stimulate the joints and muscles in the legs for full activity. Furthermore, the patient's overall height changes slightly with each step during rehabilitation walking. Due to the limited flexibility of the patient's legs and the fixed height of commonly used axillary supports, the patient may be in a semi-suspended state for a period of time during rehabilitation walking. Simultaneously, the pressure on the armpits will constantly change, and long-term rehabilitation training can easily cause significant discomfort in the armpits. This is clearly detrimental to the long-term rehabilitation care of severely injured patients and also reduces the ease of use of leg-assisting walking devices.

[0004] Therefore, it is necessary to invent a leg-assisted walking device for rehabilitation nursing to solve the above problems. It can help patients dynamically adjust their walking posture during rehabilitation training and dynamically adjust the body support height according to the patient's actual walking status.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention integrates a first auxiliary bending mechanism and a second auxiliary bending mechanism. The first and second driving motors drive the first and second positioning gears to rotate, thereby causing the second and fourth support frames to bend, simulating the natural bending movements of the human thigh and calf. This design allows patients to more accurately simulate a natural gait during rehabilitation training, effectively stimulating the joints and muscles of the legs to fully engage, and avoiding safety hazards and poor rehabilitation results caused by the legs' inability to move synchronously with the device.

[0020] 2. This invention uses a geared motor in the auxiliary walking support positioning mechanism to drive the limiting screw to rotate, thereby causing the limiting seat and the second limiting rod to move up and down, achieving height adjustment of the support protective ring and the support seat. This design allows the device to dynamically adjust the body support height based on the patient's actual walking status and data feedback from the pressure sensor, ensuring that the patient is always at the optimal height during rehabilitation training. This effectively avoids the underarm discomfort caused by the fixed height of traditional auxiliary devices, significantly improving the comfort and effectiveness of rehabilitation training.

[0021] 3. This invention, through the design of the first, second, and third lifting mechanisms, allows for personalized adjustment based on the patient's specific body dimensions (such as waist length, thigh length, and calf length). By rotating the first, second, and third positioning handles, the relative positions of the first lifting rod, the second and third support frames, and the second lifting rod and the fourth support frame can be adjusted respectively, thereby achieving personalized adaptation of the device size. This personalized design ensures that the device can accurately conform to the patient's body contours, improving the targeting and effectiveness of rehabilitation training.

[0022] 4. This invention utilizes a walking support and positioning mechanism with multiple auxiliary wheels at its base, providing a stable foundation for movement. The design of the auxiliary support ring and support diagonal rod enhances the overall stability of the device, effectively preventing safety hazards such as tipping over. Simultaneously, the shoe sole positioning plate, auxiliary limiting plate, and rotation limiting ring in the foot auxiliary positioning mechanism work together to ensure stable fixation of the patient's foot, preventing slippage and twisting during walking. Furthermore, the inclusion of a first and second elastic band further enhances the fixation effect on the knee area, reducing risks during training.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, 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.

[0042] This invention provides, for example Figure 1-15 The illustrated leg assist walking device for rehabilitation nursing includes an assist walking support and positioning mechanism 1. At both ends of the top middle position of the assist walking support and positioning mechanism 1, a first lifting mechanism 2, a first assist bending mechanism 3, a second lifting mechanism 4, a second assist bending mechanism 5, a third lifting mechanism 6, and a foot assist positioning mechanism 7 are sequentially fixedly connected.

[0043] In one specific embodiment of the present invention, the bottom end of the second lifting rod 606 is fixedly connected to a foot auxiliary positioning mechanism 7. The foot auxiliary positioning mechanism 7 includes a shoe sole positioning plate 701. One end of the shoe sole positioning plate 701 is fixedly connected to an auxiliary limiting plate 702. One end of the top of the shoe sole positioning plate 701 is rotatably connected to a rotation limiting ring 703. Pressure sensors are fixedly connected to the bottom ends of both shoe sole positioning plates 701.

[0044] A first buckle 503 is fixedly connected to one side of the third support frame 501, and a first elastic cable tie 504 is inserted through the middle of the first buckle 503. A second buckle 506 is fixedly connected to one side of the fourth support frame 505, and a second elastic cable tie 507 is inserted through the middle of the second buckle 506.

[0045] When the rehabilitation nursing leg assist walking device is needed, the patient needs rehabilitation to wear the safety pants for support and install the safety pants for support on the inside of the two first support frames 301. The patient supports their armpits on the top of the two support seats 101 and places their feet on the top of the two shoe sole positioning plates 701. The limiting ring 703 rotates and locks stably on the patient's inclined back, so that the feet are fixed. The first elastic band 504 passes through the upper end of the patient's knee and is fixed by the first buckle 503. The second elastic band 507 passes through the lower end of the patient's knee and is fixed by the second buckle 506, so that the patient is stably supported in a vertical position by the rehabilitation nursing leg assist walking device.

[0046] In one specific embodiment of the present invention, the first lifting mechanism 2 includes a first positioning frame 201, a first positioning screw 202 is rotatably connected to the middle position of the first positioning frame 201, a first movable seat 205 is threadedly connected to one end of the outer wall of the first positioning screw 202, a first lifting rod 206 is fixedly connected to one end of the first movable seat 205, the bottom end of the first positioning frame 201 is fixedly connected to the top end of the first support frame 301, a first positioning groove 204 is provided at the middle position of one side of the first positioning frame 201, one end of the first movable seat 205 is slidably connected to one end of the inner wall of the first positioning groove 204, and a first positioning handle 203 is fixedly connected to the top end of the first positioning screw 202 through the first positioning frame 201.

[0047] By rotating the first positioning handle 203, the first positioning handle 203 drives the first positioning screw 202 to rotate, which causes the first moving seat 205, which is threaded to the outer wall of the first positioning screw 202, to drive the first lifting rod 206 to rise and fall, thereby changing the positional relationship between the support seat 101 and the first support frame 301, so that the positional relationship between the support seat 101 and the first support frame 301 is equivalent to the length of the patient's waist.

[0048] In one specific embodiment of the present invention, the second lifting mechanism 4 includes a second positioning frame 401, a second positioning screw 402 rotatably connected to the middle position of the second positioning frame 401, a second movable seat 405 threadedly connected to one end of the outer wall of the second positioning screw 402, one end of the second movable seat 405 fixedly connected to the top end of the third support frame 501, the top end of the second positioning frame 401 fixedly connected to the bottom end of the second support frame 303, a second positioning groove 404 is provided at the middle position of one side of the second positioning frame 401, one end of the second movable seat 405 is slidably connected to one end of the inner wall of the second positioning groove 404, and the bottom end of the second positioning screw 402 passes through the second positioning frame 401 and is fixedly connected to a second positioning handle 403.

[0049] By rotating the second positioning handle 403, the second positioning handle 403 drives the second positioning screw 402 to rotate, which causes the second moving seat 405, which is threaded to one end of the outer wall of the second positioning screw 402, to drive the third support frame 501 to move, thereby changing the positional relationship between the second support frame 303 and the third support frame 501, so that the positional relationship between the second support frame 303 and the third support frame 501 is equal to the length of the patient's thigh.

[0050] In one specific embodiment of the present invention, the third lifting mechanism 6 includes a third positioning frame 601, a third positioning screw 602 is rotatably connected to the middle position of the third positioning frame 601, a third moving seat 605 is threadedly connected to one end of the outer wall of the third positioning screw 602, a second lifting rod 606 is fixedly connected to one end of the third moving seat 605, the top end of the third positioning frame 601 is fixedly connected to the bottom end of the fourth support frame 505, a third positioning groove 604 is provided in the middle position of one side of the third positioning frame 601, one end of the third moving seat 605 is slidably connected to one end of the inner wall of the third positioning groove 604, and the bottom end of the third positioning screw 602 passes through the third positioning frame 601 and is fixedly connected to a third positioning handle 603.

[0051] By rotating the third positioning handle 603, the third positioning handle 603 drives the third positioning screw 602 to rotate, which causes the third moving seat 605, which is threaded to one end of the outer wall of the third positioning screw 602, to move the second lifting rod 606, thereby changing the positional relationship between the fourth support frame 505 and the second lifting rod 606, so that the positional relationship between the fourth support frame 505 and the second lifting rod 606 is equal to the length of the patient's lower leg.

[0052] This ensures that the size of the leg assist walking device for rehabilitation nursing is adapted to the patient's body size, which facilitates the stimulation of the patient's joints and muscles, avoids secondary injury, and improves the comfort of rehabilitation training.

[0053] In one specific embodiment of the present invention, the auxiliary walking support positioning mechanism 1 includes an auxiliary support ring 111. First limiting rods 110 are fixedly connected to both ends of the top of the auxiliary support ring 111. Limiting frames 106 are fixedly connected to the top ends of the two first limiting rods 110. Limiting screws 107 are rotatably connected to the middle positions of the two limiting frames 106. Limiting seats 104 are threadedly connected to one end of the outer wall of each of the two limiting seats 104. Second limiting rods 103 are fixedly connected to one end of each of the two limiting frames 106. First limiting grooves 109 are formed at the middle positions of one side of each of the two limiting frames 106. One end of each of the two limiting seats 104 is slidably connected to one end of the inner wall of each of the two first limiting grooves 109. Second limiting grooves 105 are formed at the middle positions of the two second limiting rods 103. The top of one side of the frame 106 is slidably connected to one end of the inner wall of the two second limiting grooves 105. The bottom of the two limiting frames 106 is fixedly connected to the reduction motor 108. The output end of the two reduction motors 108 is fixedly connected to the bottom of the two limiting screws 107. The top of the two second limiting rods 103 is fixedly connected to the support and protection ring 102. The side of the two support and protection rings 102 is fixedly connected to the support seat 101. The middle position of the bottom of the two support seats 101 is fixedly connected to the top of the two first lifting rods 206. The bottom of the auxiliary support ring 111 is fixedly connected to multiple auxiliary wheels 113. The two ends of the two first limiting rods 110 are fixedly connected to the support inclined rods 112. The bottom of the four support inclined rods 112 is fixedly connected to the top of the auxiliary support ring 111.

[0054] Based on the data sensed by the pressure sensors fixed to the bottom of the two shoe sole positioning plates 701, the output ends of the reduction motors 108 fixed to the bottom of the two limit frames 106 respectively drive the two limit screws 107 to rotate, causing the limit seat 104 threaded to the outer wall of the limit screw 107 to slide along the first limit groove 109. This causes the second limit rod 103 fixed to one end of the limit seat 104 to drive the support protective ring 102 and the support base 101 to move up and down, and slide through the top of one side of the limit frame 106 to the second limit groove 105, thus enabling the auxiliary walking support. The positioning mechanism 1 adjusts the patient to the optimal height, which is beneficial for rehabilitation nursing exercises. Furthermore, it slightly adjusts the axillary support height according to the patient's different pressure sensing states during walking, ensuring the patient is always in a dynamic height adjustment state suitable for normal walking. This facilitates real and effective stimulation exercises during rehabilitation nursing and provides greater comfort, reducing discomfort caused by long-term training. The assisted walking support positioning mechanism 1 prevents lateral rollover in multiple directions through an auxiliary support ring 111 fixed at the bottom, and assists walking training through multiple auxiliary wheels 113 fixed at the bottom of the auxiliary support ring 111.

[0055] Before and after training, by controlling the overall height of the assisted walking support positioning mechanism 1, it is easy to support the patient from the chair and relax the patient in the chair. This avoids the need for multiple people to assist the patient in getting on and off the device due to fixed equipment. It not only avoids secondary injury caused by improper operation, but also reduces the risk of psychological harm to the patient.

[0056] The first auxiliary bending mechanism 3 includes a first support frame 301, a second support frame 303 rotatably connected to the bottom end of the first support frame 301, a first positioning gear ring 302 fixedly connected to one end of one side of the first support frame 301, a first fixing frame 304 fixedly connected to one end of one side of the second support frame 303, a first positioning gear 306 rotatably connected to one side of the first fixing frame 304, and the tooth surface of the first positioning gear 306 meshing with the tooth surface of the first positioning gear ring 302.

[0057] A first drive motor 307 is fixedly connected to the other side of the first fixed frame 304. The output end of the first drive motor 307 is fixedly connected to the middle position of the first positioning gear 306. A first protective ring 305 is fixedly connected to one side of the first fixed frame 304. The inner wall of the first protective ring 305 slides in contact with the outer wall of the first positioning gear ring 302.

[0058] The second auxiliary bending mechanism 5 includes a third support frame 501, a fourth support frame 505 rotatably connected to the bottom end of the third support frame 501, a second positioning gear ring 502 fixedly connected to one end of one side of the third support frame 501, a second fixing frame 508 fixedly connected to one end of one side of the fourth support frame 505, a second positioning gear 510 rotatably connected to one side of the second fixing frame 508, and the tooth surface of the second positioning gear 510 meshing with the tooth surface of the second positioning gear ring 502.

[0059] The output end of the first drive motor 307, which is fixed to one side of the first fixed frame 304, drives the first positioning gear 306 to rotate, so that the tooth surface of the first positioning gear 306 meshes with the tooth surface of the first positioning gear ring 302. Since the positions of the first support frame 301 and the first positioning gear ring 302 are fixed, the first positioning gear 306 drives the second support frame 303 to rotate, so that the first positioning gear ring 302 rotates stably under the protection of the first protective ring 305.

[0060] A second drive motor 511 is fixedly connected to the other side of the second fixed frame 508. The output end of the second drive motor 511 is fixedly connected to the middle position of the second positioning gear 510. A second protective ring 509 is fixedly connected to one side of the second fixed frame 508. The inner wall of the second protective ring 509 slides in contact with the outer wall of the second positioning gear ring 502.

[0061] The output end of the second drive motor 511, fixed to one side of the second fixed frame 508, drives the second positioning gear 510 to rotate, so that the tooth surface of the second positioning gear 510 meshes with the tooth surface of the second positioning gear ring 502. Since the relative positions of the third support frame 501 and the second positioning gear ring 502 are fixed, the second positioning gear 510 drives the fourth support frame 505 to rotate, so that the second positioning gear ring 502 rotates stably under the protection of the second protective ring 509. This allows the patient's torso, thighs, and calves to be in a semi-autonomous state, and the range of motion is adjusted by a pressure sensor, making it easier for severely ill patients to receive precise walking assistance, avoiding the hidden danger of being dragged along. This truly enables severely ill patients to receive rehabilitation training, effectively preventing muscle atrophy, and providing effective treatment for severely ill patients using leg-assisted walking devices for rehabilitation nursing.

[0062] In one specific embodiment of the present invention, an intelligent control panel is fixedly connected to one side of one of the second limiting rods 103. The pressure sensor, the reduction motor 108, the first drive motor 307 and the second drive motor 511 are all electrically connected to an external power supply through the intelligent control panel.

[0063] This device, through its design that simulates a natural gait, dynamically adjusts support height, and provides personalized size adaptation, effectively promotes the recovery of leg muscle strength and the remodeling of nerve function in patients.
