Description

Technical Field

[0001] This utility model relates to the field of rehabilitation exercise equipment technology, specifically a self-rehabilitation exercise device for the lower limbs of stroke hemiplegic patients. Background Technology

[0002] The lower limb self-rehabilitation exercise device for stroke hemiplegic patients is an intelligent rehabilitation device designed to help patients restore lower limb motor function. It mainly stimulates neuroplasticity through active training and promotes limb function reconstruction. Therefore, it is widely used in rehabilitation nursing and other fields. When stroke hemiplegic patients use rehabilitation exercise devices for rehabilitation exercises, most of them directly use the rehabilitation exercise devices for rehabilitation nursing. However, the existing rehabilitation exercise devices have poor protection when in use and do not have protective mechanisms to protect the users, which leads to poor practicality of the rehabilitation exercise devices.

[0003] To overcome the above-mentioned defects, in the prior art 1 (Chinese patent application number CN202121001496.6, application date 2021-05-11), the lower limb autonomous function exercise assistive device for hemiplegic patients uses a recovery machine to drive the foot pedal to rotate, thereby achieving the effect of automatically exercising the legs of hemiplegic patients. The restraint straps on the restraint shoes, combined with Velcro, make it easy for caregivers to put the hemiplegic patient's feet into the restraint shoes and to restrain and fix the hemiplegic patient's feet, preventing the hemiplegic patient's feet from falling off the foot pedal when the recovery machine is working, thus reducing safety hazards. The elastic potential energy of the spring drives the massage ball to slide up and down in the mounting groove, thereby achieving the purpose of massaging the soles of the hemiplegic patient's feet, which is beneficial to the recovery of hemiplegic patients.

[0004] While existing technologies can provide protective measures for patients to improve the safety of rehabilitation exercise equipment, the actual use of such equipment is limited because the swing frame lacks an adjustment mechanism to hold and position the patient during rehabilitation, preventing the patient's legs from loosening and falling off during exercise. Therefore, the proposed lower limb autonomous rehabilitation exercise device for stroke hemiplegic patients can effectively solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a self-rehabilitation exercise device for the lower limbs of stroke hemiplegic patients, in order to solve the problem mentioned in the background art that the current rehabilitation exercise devices on the market have poor practicality because the swing frame does not have an adjustment mechanism on the outside to hold and position the patient during rehabilitation, thus preventing the patient's leg from loosening and falling off during later rehabilitation exercises.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-rehabilitation exercise device for the lower limbs of a stroke hemiplegic patient, comprising a base, wherein a support frame for positioning and installation is provided above the base, and a seat is provided above the support frame, and a swing frame is rotatably installed on the left side of the seat, and two stops are mounted on opposite sides of the bottom ends of the two swing frames, and a limiting plate is slidably installed through the outer surface of the two stops, and the diameter of the limiting plate is larger than the diameter of the stops, while the two swing frames are inclined, and a rotating shaft is rotatably installed inside the seat, and the left end of the rotating shaft extends through to the outside of the seat, and a pull rope is connected to the left side of the rotating shaft.

[0007] Preferably, a limiting rod is slidably installed through the front side of the limiting plate, and the inner end of the limiting rod is connected through a limiting groove, wherein a row of limiting grooves is opened at equal intervals.

[0008] Preferably, the limiting rod and the limiting groove form an engaging structure.

[0009] Preferably, one end of a tension spring is connected to the outer surface of the limiting rod, and the other end of the tension spring is connected to a limiting plate.

[0010] Preferably, a row of eccentric massage wheels is mounted on the outer surface of the rotating shaft, and the row of eccentric massage wheels is evenly spaced inside the seat, and the top inner wall of the seat is attached to the top of the row of eccentric massage wheels.

[0011] Preferably, two air-storage airbags are symmetrically installed inside the seat, and the four air-storage airbags have the same structure. The bottom of the air-storage airbags is provided with an exhaust port, and the outer side of the air-storage airbags is provided with an air inlet port.

[0012] Preferably, the outer side of the eccentric massage wheel corresponds to an air storage bag, the top of the exhaust port corresponds to a ventilation slot, and the ventilation slot is formed on the surface of the seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) A limiting plate is set up. The limiting plate is installed through the outside of the stop bar. The patient’s leg rehabilitation exercise can be limited by the limiting plate to avoid the patient’s leg from being misaligned during exercise, so as to improve the exercise efficiency of the anti-segment exercise equipment.

[0015] (2) Furthermore, when patients of different body types use the rehabilitation exercise equipment for rehabilitation exercises, they only need to pull the limiting rod outward to separate the limiting rod from the limiting groove. At this time, the limiting plate can be moved to the outside of the stop bar to move its position, which makes it convenient for patients of different body types to use the rehabilitation exercise equipment for rehabilitation exercises, and it is more practical.

[0016] (3) Furthermore, by using a tension spring on one end of the limit rod and connecting a limit plate to the other end of the tension spring, the position of the limit rod after being pulled can be elastically reset by the tension spring itself, so that the limit rod after being pulled can automatically spring into the inside of the limit groove, thereby limiting and fixing the position of the limit plate after movement, avoiding the phenomenon of loosening and displacement of the limit plate during use, and improving stability.

[0017] (4) A rotating shaft is provided. One end of the pull rope is connected to the bottom of the swing frame, and the other end of the pull rope is connected to the rotating shaft through the guide wheel. When the patient drives the swing frame to perform swing rehabilitation exercises by moving the stop bar with his legs, the pull rope connected to the bottom of the swing frame will pull the rotating shaft connected inside the seat through the guide wheel to rotate. At this time, a row of eccentric massage wheels set on the outer surface of the rotating shaft will rotate inside the seat, so that the patient's buttocks can be rotated and massaged through a row of eccentric massage wheels, thereby improving the patient's comfort.

[0018] (5) Furthermore, when the rotating shaft drives a row of eccentric massage wheels to rotate for massage, the row of eccentric massage wheels will also squeeze the four air storage bags at the same time. At this time, the four air storage bags will release the gas stored inside through the exhaust hole and then through the ventilation hole groove to the top outer side of the seat, so as to ventilate the patient's buttocks and avoid the accumulation of heat on the surface of the seat, which would affect the patient's exercise comfort.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides the following technical solution: a device for autonomous rehabilitation exercises of the lower limbs of stroke patients with hemiplegia.

[0029] Example 1: To address the problem that existing rehabilitation exercise equipment is impractical due to the lack of an adjustment mechanism on the outer side of the swing frame 4 to hold and position the patient during rehabilitation, thus preventing the patient's legs from loosening and falling off during exercise, the following solution is disclosed: a base 1, with a support frame 2 for positioning and installation on top of the base 1, and a seat 3 on top of the support frame 2. The swing frame 4 is rotatably mounted on the left side of the seat 3. The bottom ends of the two swing frames 4 are mounted with opposing stops 5, and the outer surfaces of the two stops 5 are slidably fitted with limit plates 6, the diameter of which is larger than the diameter of the stops 5. The two swing frames 4 are tilted. A rotating shaft 9 is rotatably mounted inside the seat 3, with its left end extending to the outer side of the seat 3, and a pull rope 8 connected to the left side of the rotating shaft 9.

[0030] A limiting rod 10 is slidably installed through the front side of the limiting plate 6, and the inner end of the limiting rod 10 is connected through a limiting groove 11. One row of limiting grooves 11 is equally spaced. The limiting rod 10 and the limiting groove 11 form a locking structure. One end of a tension spring 12 is connected to the outer surface of the limiting rod 10, and the other end of the tension spring 12 is connected to the limiting plate 6.

[0031] like Figures 1-3As shown, when patients of different body types use the rehabilitation exercise equipment for rehabilitation exercises, they only need to place their legs inside the limiting plate 6, and then pull the limiting rod 10 outward to separate the limiting rod 10 from the limiting groove 11. At this time, the limiting plate 6 can be moved to adjust its position so that the moved limiting plate 6 fits the patient's leg, preventing the patient's leg from shifting during exercise, thereby improving the exercise efficiency of the anti-segmentation exercise equipment. After the limiting plate 6 is adjusted to the appropriate position, the limiting rod 10 is released. At this time, the tension spring 12 will elastically reset the position of the pulled limiting rod 10 through its own elasticity, so that the pulled limiting rod 10 will automatically spring into the interior of the limiting groove 11, thereby limiting and fixing the position of the limited plate 6 after adjustment and preventing the limiting plate 6 from shifting during subsequent rehabilitation exercises, thus improving stability.

[0032] Example 2, unlike Example 1, allows for the simultaneous use of the rehabilitation exercise equipment by engaging the massage and ventilation mechanisms to enhance patient comfort and improve the practicality of the rehabilitation exercise equipment. The following is disclosed:

[0033] A row of eccentric massage rollers 13 is installed on the outer surface of the rotating shaft 9. The row of eccentric massage rollers 13 is evenly spaced inside the seat 3. The top inner wall of the seat 3 is attached to the top of the row of eccentric massage rollers 13. Two air storage bags 14 are symmetrically installed inside the seat 3. The four air storage bags 14 have the same structure. The bottom of the air storage bag 14 is provided with an exhaust hole 15. The outer side of the air storage bag 14 is provided with an air inlet 16. The outer side of the eccentric massage rollers 13 corresponds to the air storage bag 14. The top of the exhaust hole 15 corresponds to the ventilation hole groove 7. The ventilation hole groove 7 is opened on the surface of the seat 3.

[0034] like Figures 1-6As shown, when a patient uses the rehabilitation exercise equipment, the swinging frame 4 drives the pull rope 8 to pull the rotating shaft 9 inside the seat 3 through the guide wheel. At this time, the rotating shaft 9 drives a row of eccentric massage rollers 13 to rotate and massage the patient's buttocks sitting on the surface of the seat 3, thereby improving the patient's comfort. After the swinging frame 4 swings back to its original position, the return spring 17 will also elastically reset the position of the rotating shaft 9 through its own elasticity, so as to facilitate repeated massage in the future, thus improving the comfort of the rehabilitation exercise equipment. While the rotating shaft 9 drives the row of eccentric massage rollers 13 to rotate and massage, the row of eccentric massage rollers 13 will also squeeze the four air storage bags 14 at the same time. At this time, the four air storage bags 14 will discharge the gas stored inside through the exhaust hole 15 to the outside of the ventilation slot 7, thereby ventilating the patient's buttocks and preventing pressure sores from forming on the patient's buttocks due to prolonged sitting pressure. This improves the ventilation effect of the patient's buttocks and enhances its practicality.

[0035] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
