Description

leg rehabilitation device

technical field

The utility model relates to a rehabilitation device, in particular to a leg rehabilitation device.

Background technique

In the early days of the advent of rehabilitation medicine, rehabilitation was only aimed at the dysfunction left behind in the later stage of injury or illness, so it was called "post-therapy". However, with the development of rehabilitation medicine, many deficiencies of "post-therapy" have been exposed, such as joint pain, contracture pressure ulcers, etc., using "post-therapy" for rehabilitation is often half the result with twice the effort, and some functions are even eventually abandoned and cannot be restored. . Some patients, such as those with legs, may be able to regain their original motor function with the help of rehabilitation equipment.

At present, leg rehabilitation in the domestic and foreign markets is mostly in the form of doctors leading patients to perform dexterous mechanical movements, and the process is relatively simple. Most of the equipment used is electromagnetic, vibration, etc. to stimulate blood vessels and nerves. Although the regeneration of cells and tissues can be restored quickly, it has little effect on the recovery of the original exercise ability of the postoperative patient.

Sports-based rehabilitation equipment is not uncommon, but most of them are designed for the rehabilitation of athletes. The rehabilitation effect is highly targeted, and the recovery effect on the overall performance of the body is not good, so it is not suitable for ordinary people to use. In addition, the prices of similar products are generally high, and cannot effectively serve a large number of patients suffering from leg disorders.

Therefore, an ideal leg rehabilitation device should be: simple in structure, easy to operate by ordinary people, and can independently perform leg rehabilitation at an appropriate time, not limited to individuals, so as to improve the living conditions of patients. At the same time, the price should be moderate so that ordinary patients can afford it.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a leg rehabilitation device, which can reduce the movement burden on the legs during the rehabilitation process of the legs, and the movement load can be adjusted independently by the patient to adapt to the rehabilitation process. progress. At the same time, it can solve leg diseases caused by various problems, promote the rehabilitation of legs, and improve the quality of life of patients.

The technical solution adopted by the utility model to solve the technical problems is: comprising a back chair and a driving device, the driving device is composed of a handle symmetrically arranged on both sides of the chair frame, a crank rocker and a synchronous transmission mechanism. Rocking bar, its upper end is connected with the eccentricity of large pulley by handle, and pedal is equipped with at the lower end. The synchronous transmission mechanism is composed of a long shaft, a small pulley and a large pulley, the two pulleys are connected by a belt, and the small pulley is fixedly connected with the end of the long shaft. The support frame is connected with the chair frame bolts, and one end is movably connected with the wheel shaft of the large pulley, and the other end is equipped with a sliding sleeve, which is slidably connected with the chute on the connecting rod. The support frame is connected with the small pulley through the long axis.

Compared with similar products, the utility model has the following main advantages:

Firstly, it takes the patient's own movement as the main form, avoiding problems such as low postoperative movement ability.

Second, it has complete functions, which is conducive to the comprehensive recovery of patients' illnesses.

Third. It is not powered by electricity, which saves energy.

Fourth, the structure is simple, the operation is convenient, the movement is stable, the price is moderate, and it is suitable for the needs of the masses.

Detailed ways

The utility model is associated with outdoor fitness equipment, and the upper limbs drive the lower limbs to exercise, so that the burden on the legs caused by exercise can be reduced during the leg rehabilitation process, and the exercise load can be adjusted independently by the patient. in order to adapt to the progress of rehabilitation.

Below in conjunction with embodiment and accompanying drawing, the utility model is further described.

The structure of the utility model is shown in Fig. 1, Fig. 2 and Fig. 3: it includes a back chair and a driving device, and the driving device is composed of a handle 3, a rocker 4, a support frame 13 and a synchronous transmission mechanism arranged symmetrically on both sides of the chair frame. . Rocking bar 4, its upper end links to each other by the eccentricity of handle 3 and large pulley 15, and pedal 11 is equipped with in the lower end. The synchronous transmission mechanism is made up of major axis 7, small pulley 6 and large pulley 15, and two pulleys are connected with belt, and small pulley is fixedly connected with long axis end. Support frame 13 is connected with chair frame 5 bolts, and its one end is flexibly connected with the wheel shaft of large pulley 15, and the other end is equipped with sliding sleeve 9, and support frame 13 is connected with small pulley 6 by major axis 7, and sliding sleeve 9 is connected with rocking bar The chute 8 on the 4 is slidingly connected.

Can be connected pedal 11 by welding or bolt connection mode at the tortuous place of rocking bar 4 lower ends. The front end of the pedal 11 is provided with an arc-shaped baffle plate 12 to step on the pedal 11 with the feet.

Described major axis 7, its axle body is connected with the chair frame 5 of chair frame by bearing.

Described chair frame 5, the supports at the two ends of the bottom frame 10 are inverted U-shaped frames, and the ends of the U-shaped frame can be equipped with anti-slip sleeves. For the patient to sit comfortably, a backrest 1, an armrest 2 and a seat cushion 14 can be provided. The backrest 1 and the armrest 2 are welded together with the chair frame 5 at the lower part; at the same time, several holes can be drilled on both sides of the chair frame, and the backrest 1 and the chair frame 5 can be adjusted to a certain degree by using bolts or bolts to cooperate with these holes. Angle to meet the patient's sitting posture requirements.

Above-mentioned big belt pulley 15 is connected with chair frame 5 by screw, and little belt pulley 6 is connected with major shaft 7 with bearing, and their effect is to guarantee that the synchronous pulley speed is consistent. Rocking bar 4 belongs to rotating connection with big belt pulley 15, so that rocking bar is reciprocated back and forth.

In order to see the figure clearly, Fig. 2 does not draw the belt connecting small pulley 6 and large pulley 15.

The working process of the utility model is: use the hand as the driving force, that is, the handle 3 is driven by hand to rotate the large pulley 15, and the rotation of the large pulley 15 drives the constraint of the slider 9 of the rocking bar 4 on the support frame 13 Do reciprocating motion along chute 8, thereby make pedal 11 do reciprocating motion under the drive of rocking bar 4, thereby make leg also reciprocating motion. On the contrary, also can utilize pin to make driving force, promptly realize the rotation of big pulley 15 with pin stepping on pedal 11, action is the same as above later on. Both of these methods can achieve the purpose of leg rehabilitation.

While moving, the transmission of the large pulley 15 drives the small pulley 6 to rotate together with the major axis 7, thereby realizing synchronous movement on both sides. And because the long axis 7 participates in the movement, the simultaneous linkage of the upper and lower limbs can be realized, which provides a platform for the diversified selection of rehabilitation exercises.

When using the utility model, its concrete rehabilitation process is divided into 3 stages:

1) After the operation, the patient is unable to do rehabilitation exercises by himself, so he needs to perform appropriate rehabilitation exercises with the assistance of others.

2) After a period of time, the patient uses his upper limbs to drive his lower limbs to perform rehabilitation exercises.

3) Finally, the lower limbs are detached from the upper limbs, and do voluntary recovery exercises.
