Description

Lower limb exercise device

Technical Field

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

Background

For patients with symptoms causing movement disorders, it is generally necessary to perform corresponding rehabilitation exercises, such as rehabilitation exercises of lower limbs. The rehabilitation exercise comprises passive exercise and active exercise, and when rehabilitation exercise is performed in the early stage, the rehabilitation exercise is difficult to be completed autonomously due to the limited physical recovery degree of a patient, and medical staff is often required to assist the rehabilitation exercise to complete the rehabilitation exercise, namely, the passive exercise is performed; after the body of the later-stage patient recovers to a certain degree, rehabilitation exercise can be performed autonomously, namely active exercise is performed.

Currently, when performing passive exercise of lower limbs, in order to reduce the working intensity of medical staff, a corresponding lower limb exercise device is adopted to assist a patient in performing lower limb exercise. The existing lower limb exercise device is mostly composed of a seat, armrests and a mechanism for driving a patient to perform leg bending and stretching exercises, so as to assist the patient to perform leg bending and stretching exercises by himself. Because the existing lower limb exercise device cannot correspondingly adjust the whole structure according to the height and the body type of a patient, the patient with the height and the body type inconsistent with the design size of the lower limb exercise device feels uncomfortable and even cannot normally use the lower limb exercise device in the using process.

In order to solve the problem that the lower limb exercise device cannot adapt to the heights and the body shapes of different patients, the prior art discloses a limb exercise device (authorized bulletin number: CN 213823333U) for diabetics, which comprises a seat, wherein armrests are arranged on two sides of the seat, a chair back is hinged to the rear side of the top of the seat, and a leg guard plate is hinged to the front side of the seat; the bottom of the seat is connected with a fixed leg, a supporting leg is movably connected in the fixed leg, one side of the fixed leg is connected with an electric telescopic rod, and the output end of the electric telescopic rod is connected with a leg guard plate. When the limb exercise device is used for assisting a patient in carrying out passive exercise on lower limbs, the height of the chair seat can be adjusted according to the height of the patient, and the inclination of the chair back can be adjusted according to the body type of the patient, so that the use comfort of the patient is improved, and the practicability is improved.

However, the above prior art has the following problems when in use:

1. when the height of the seat is adjusted according to the height of a patient, medical staff is required 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; when the inclination angle of the chair back is adjusted according to the body shape of a patient, medical staff is required to rotate the chair back to adjust; thus, the adjustment of the height of the seat and the inclination angle of the seatback by the medical staff still results in a great work intensity for the medical staff.

2. When the lower limb exercise is performed, the knee part of the patient needs to correspond to the hinge joint of the seat and the leg guard, so that the lower leg of the patient is attached to the leg guard and the knee bending exercise is completed along with the rotation of the leg guard; because the chair back is fixed relative to the position of the chair seat, after the knee part of a patient with a shorter height is placed in place, the back of the patient is difficult to be attached to the chair back, so that the supporting force provided by the chair back for the patient is reduced, the patient cannot keep a comfortable posture for exercise, the exercise effect is greatly reduced, and the patient is tired easily; and after the back of the patient with higher height is attached to the chair back, the knee part of the patient exceeds the hinge joint of the chair seat and the leg guard, so that the lower leg of the patient cannot be attached to the leg guard, and the effect of knee bending exercise is affected.

3. The leg guard can only drive patient's shank to carry out the knee bending motion, leads to the low limbs exercise mode singleness, is difficult to reach good low limbs exercise effect.

With the lower limb exercise device described in this embodiment, the rotating frame 205 is driven by the rotating motor 201 to rotate clockwise and anticlockwise, so that the pushing plate 206 always keeps contact with the leg of the patient under the action of the compression spring 210 in the process of supporting and putting down the leg of the patient, and thus the leg of the patient can be continuously massaged by the electric massaging block 207 arranged on the outer side of the pushing plate 206, which is beneficial to ensuring the rehabilitation exercise effect of the lower limb of the patient, and greatly enhancing the practicability of the whole device.

Example 3

A lower limb exercise apparatus, as shown in fig. 6, which differs from embodiment 2 in that: the mounting bracket 601 and remove cover 401 along left and right sides direction sliding connection, remove cover 401 on fixedly connected with rotation motor 604, rotation motor 604's output fixedly connected with two-way screw 605, remove cover 401 and two-way screw 605 threaded connection. Specifically, mounting plates 606 are integrally formed at positions, close to two sides, of the bottom of the movable sleeve 401, mounting holes are formed at positions, corresponding to the mounting frames 601, of the mounting plates 606, and the mounting frames 601 are slidably connected in the mounting holes; the rotating motor 604 is fixedly connected to the mounting plate 606 through screws, a threaded hole is formed in the position, corresponding to the bidirectional screw 605, of the mounting frame 601, and the two mounting frames 601 are respectively in threaded connection with two sections of threads of the bidirectional screw 605.

By using the lower limb exercise device disclosed by the embodiment, the distance between the two holding plates 603 can be adaptively adjusted according to the body shape of a patient, so that the patient is ensured to hold the holding plates 603 in a comfortable posture to support the body, and the fatigue feeling of the patient in the lower limb exercise process is reduced, thereby improving the exercise effect. Specifically, when the rotating motor 604 is started, the rotating motor 604 drives the bidirectional screw 605 to rotate clockwise or anticlockwise, and the mounting frames 601 on two sides of the seat board 101 are simultaneously moved away from the seat board 101 or towards the seat board 101 under the driving of the bidirectional screw 605, that is, the mounting frames 601 on two sides are mutually separated or close to each other, so as to realize the adjustment of the distance between the two new holding boards 603.

The foregoing is merely exemplary of the present invention, and specific technical solutions and/or features that are well known in the art have not been described in detail herein. It should be noted that, for those skilled in the art, several variations and modifications can be made without departing from the technical solution of the present invention, and these should also be regarded as the protection scope of the present invention, which does not affect the effect of the implementation of the present invention and the practical applicability of the patent. The protection scope of the present application shall be subject to the content of the claims, and the description of the specific embodiments and the like in the specification can be used for explaining the content of the claims.
