Description

A lower limb exercise device

technical field

The invention relates to the technical field of exercise aids, in particular to a lower limb exercise device.

Background technique

For patients with movement disorders caused by diseases, corresponding rehabilitation exercises are generally required, such as rehabilitation exercises for lower limbs. Rehabilitation exercise includes passive exercise and active exercise. In the early stage of rehabilitation exercise, due to the limited degree of physical recovery of the patient, it is difficult to complete the rehabilitation exercise independently. Medical staff are often required to assist them in completing the exercise, that is, passive exercise; , can independently carry out rehabilitation exercise, that is, active exercise.

At present, in order to reduce the work intensity of the medical staff during the passive exercise of the lower limbs, corresponding lower limb exercise devices are used to assist patients in lower limb exercise. Most of the existing lower limb exercise devices are composed of seats, armrests and mechanisms for driving patients to perform leg flexion and extension exercises, so as to assist patients to complete the exercise of leg flexion and extension by themselves. Since the existing lower limb exercise device cannot adjust the overall structure according to the patient's height and body shape, patients whose height and body shape do not match the design size of the lower limb exercise device feel uncomfortable or even unable to use it normally.

In order to solve the problem that the above-mentioned lower limb exercise device cannot adapt to the height and body shape of different patients, the prior art discloses a limb exercise device for diabetic patients (authorized announcement number: CN213823333U), including a seat, and armrests are provided on both sides of the seat , the back of the top of the seat is hinged with the seat back, and the front of the seat is hinged with a leg guard; the bottom of the seat is connected with a fixed leg, and the fixed leg is movably connected with a support leg, and one side of the fixed leg is connected with an electric telescopic rod. The output end of the electric telescopic rod is connected with the leg guard. When the limb exercise device is used to assist patients in passive lower limb exercise, the height of the chair seat can be adjusted according to the height of the patient, and the inclination angle of the chair back can be adjusted according to the body shape of the patient, so as to improve the comfort and practicability of the patient.

But above-mentioned prior art also has following problem when using:

1. When adjusting the height of the seat according to the patient's height, the medical staff needs to hold the handle to drive the seat to move up and down, so that the supporting legs move up and down in the fixed legs to adjust the height of the seat; adjust according to the patient's body shape When the inclination angle of the chair back is adjusted, the medical staff needs to rotate the chair back to adjust; therefore, the adjustment of the height of the seat and the inclination angle of the chair back by the medical staff will still cause the medical staff to work harder.

2. When performing lower limb exercises, the patient's knee needs to correspond to the hinge of the seat and the leg guard, so that the patient's calf fits the leg guard and follows the rotation of the leg guard to complete the knee flexion exercise; due to the position of the chair back relative to the seat Fixed, after a short patient puts the knees in place, it is difficult for the back to fit the back of the chair, resulting in the reduction of the support provided by the chair back to the patient, making it impossible for the patient to maintain a comfortable posture for exercise, which will not only cause exercise The effect is greatly reduced, and it is easy to cause fatigue to the patient; and for taller patients, after the back is fitted to the back of the chair, the knee will exceed the hinge between the seat and the leg guard, resulting in the inability of the calf to fit the leg guard , thus affecting the effect of knee flexion exercise.

3. The leg guard can only drive the patient's legs to perform knee-bending motion, resulting in a single way of lower limb exercise, making it difficult to achieve a good lower limb exercise effect.

Specifically, the bottom of the moving sleeve 401 is integrally formed with a mounting plate 606 near the two sides, and the mounting plate 606 has a mounting hole corresponding to the position of the mounting frame 601, and the mounting frame 601 is slidably connected in the mounting hole; the rotating motor 604 is fixed by screws Connected to the mounting plate 606 , the mounting frame 601 is provided with a threaded hole corresponding to the position of the two-way screw 605 , and the two mounting frames 601 are threadedly connected to the two sections of the two-way screw 605 respectively.

Using a lower limb exercise device described in this embodiment, the distance between the two gripping boards 603 can be adaptively adjusted according to the body shape of the patient, so as to ensure that the patient holds the gripping board 603 in a comfortable posture to support the body, reducing the The patient's fatigue during lower limb exercise can improve the effect of exercise. Specifically, start the rotating motor 604, and the rotating motor 604 drives the two-way screw 605 to rotate clockwise or counterclockwise, and the mounting brackets 601 on both sides of the seat plate 101 will move away from the seat plate 101 or approach the seat plate simultaneously under the drive of the two-way screw 605. The direction of 101 moves, that is, the mounting brackets 601 on both sides move away from or approach each other, so as to realize the adjustment of the distance between the two gripping plates 603 .

What is described above is only an embodiment of the present invention, and common knowledge such as specific technical solutions and/or characteristics known in the solutions will not be described here too much. It should be pointed out that for those skilled in the art, without departing from the technical solutions of the present invention, some modifications and improvements can also be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation of the present invention effect and utility of the patent. The scope of protection required by this application shall be based on the content of the claims, and the specific implementation methods and other records in the specification may be used to interpret the content of the claims.
