Description

A knee-shoulder joint exercise rehabilitation device

technical field

The invention relates to the field of medical rehabilitation equipment, in particular to a knee-shoulder joint joint exercise rehabilitation device.

Background technique

Arthritis is one of the most common chronic diseases in the world. It is mainly the degeneration of cartilage in the joints or inflammation of the connective tissue, which causes joint pain and interferes with the normal movement of the joints. Knee arthritis and shoulder arthritis are common in the elderly and heavy physical strength. There are two types of arthritis in the labor population, and there is a certain correlation between the two. At present, the treatment of arthritis includes drugs, surgery and physical exercise rehabilitation.

The sports rehabilitation of contemporary arthritis mainly includes two categories: manual exercises and special sports rehabilitation equipment:

1. Freehand exercises

Freehand exercises are prepared by professional physicians and practiced by patients. The disadvantage of this rehabilitation method is that its movements are often standing, and the sick middle-aged and elderly people with knee injuries cannot stand for a long time. At the same time, it is common for middle-aged and elderly people to be overweight, and the knees bear all their own weight when standing. , people of different weights and illnesses cannot produce the same effect with the same set of freehand exercises;

At the same time, shoulder arthritis is mainly caused by long-term heavy-duty labor or desk work, and the pathological locations of its pathological locations are different (for example, the shoulder joint injuries of workers who lift, carry, and pull for a long time are different from those who do writing work), and it is difficult to take into account the different movements of bare-hand exercises. The cause of the disease may be aggravated by repeated practice of the action that triggers the disease.

2. Sports rehabilitation equipment

There are a variety of products designed for the sports rehabilitation needs of arthritis patients in the prior art, such as:

CN206026964U multifunctional rheumatoid arthritis exercise rehabilitation machine

When using it, patients are required to stand and run, and generally patients with knee arthritis do not have the physical conditions for walking and running exercises (running has a greater impact on the knees);

CN107335182A A kind of rheumatoid arthritis sports rehabilitation auxiliary machine

It adopts a supine position, and the user stirs the winch with his hands to drive the lower limbs to move to achieve the purpose of activity. However, it requires the patient to lie down and use it, raise the hand to shake the disc, which consumes a lot of physical strength, and can only drive the lower limbs to move slightly. exercise lower body strength;

CN109481237A A kind of rehabilitation device for knee arthritis patients

The device is in a sitting position, and uses a motor to drive the gear set to form a reciprocating motion. The patient's lower limbs are placed in the reciprocating motion components to follow. It only has the function of moving the limbs and cannot achieve the purpose of exercise and rehabilitation.

3. For middle-aged and elderly patients, whose physical strength cannot support them to stand for a long time or push mechanical mechanisms, the rehabilitation action requires a certain resistance, but the resistance should not be too large; at the same time, for middle-aged and elderly patients, the movements that require rehabilitation are mainly going up and downstairs, sitting The actions actually required in daily life, such as getting up and getting up from lying down, etc., there is no arthritic exercise rehabilitation device that meets the above requirements in the prior art, and the device in the prior art is only suitable for one ward and knee. Associated shoulder arthritis, waist disease still need other equipment.

Slot 9, the outer ends of the two cross bars 8 are respectively placed in the chute 9 on the same side, and the rotation of the first gear 7 can drive the two pedals 5 to move up and down through the two cross bars 8;

It also includes two groups of traction mechanisms, each group of traction mechanisms includes a traction rope 10 and a pull ring 11, the front ends of the two traction ropes 10 are respectively fixed on the two pedals 5, and the rear ends of the two traction ropes are The wire devices are wound to the rear side of the seat plate 3 and cross each other, and the two pull rings 11 are respectively fixed to the rear ends of the two traction ropes 10 .

The first gear 7 is meshed with a second gear 12 , and the second gear 12 is connected with a driving motor 13 .

The two cross bars 8 are removably inserted on the first gear 7 via the sliding keys.

The upright column 2 is a pneumatic telescopic rod structure, so that the height of the seat plate 3 can be adjusted.

The seat plate 3 is rotatably installed on the upper end of the upright column 2, and the patient can cooperate to perform waist twisting action.

The seat plate 3 is provided with a backrest 14, and the lower end of the backrest 14 is hinged on the seat plate 3 and provided with locking screws, so that the back angle of the backrest 14 can be adjusted; patients, the program can be used in a semi-reclining position.

The guide wire device includes a plurality of limit rings 15 arranged on the base 1 and the back surface of the backrest 14 along the path of the traction rope 10. The traction rope 10 passes through the limit rings 15 in turn and goes around to the rear side of the backrest 14, and also includes two A steering wheel 16 is respectively installed on the upper end of the guide rods 4 on both sides.

The traction rope 10 is elastic, and a locking screw is installed on the side of each pedal 5 to lock it on the guide rod 4, so that only the arms can be exercised when the legs are not moving. The reverse rotation traction rope 10 action, which becomes a device for rehabilitation of shoulder arthritis only.

The limiting rings 15 on the backrest 14 include two groups arranged symmetrically on the left and right, and each group includes a plurality of uniformly distributed rectangles.

A headrest 17 is installed on the backrest 14 through a spring, and three hooks 18 arranged on the left, middle and right are installed on the rear surface of the headrest 17 , and the pull ring 11 can be hung on the hooks 18 .

The using method of the present invention is as follows:

When the patient needs to actively exercise, the two cross bars 8 are removed from the first gear 7. The patient sits on the seat plate 3 and steps on the corresponding pedals 5 alternately with both feet. The compression springs 6 provide resistance, while the pedals 5 are pulled downwards The rope 10, the patient's arms are swung behind him and the wristband is pulled, and the traction rope 10 makes the patient's arms make a "reverse rotation" action behind the back. Action, this action is almost never used in labor, so it will not aggravate the patient's condition, and can adapt to shoulder injuries caused by any type of work; the pedal 5 simulates the action of going upstairs and stairs, which is aimed at middle-aged and elderly people. requires targeted practice.

When the pull ring 11 is not pulled by both hands, the mechanism can only exercise the lower limbs, or only one foot, or only the upper limbs on one side + the lower limbs on the other side; lock the pedal 5 and simply pull the traction rope 10 Only the shoulder joint can be exercised, so there are various forms of exercise.

The traction rope 10 passes through the limit ring 15 on the backrest 14 from bottom to top, and the path can be arbitrarily selected to adjust the length, and finally comes out from the top row of specific hooks, if it passes through the outermost limit ring 15 , it corresponds to the "anti-rotating arm" action with a larger opening angle of the arms. If it passes through the innermost limit ring 15, it corresponds to the "anti-rotating arm" action with a small opening angle of the arms. , if it passes through a certain limit ring 15 in the middle, the outward opening degree of the arm is between the two.

When the neck joint needs to be exercised, the two pull rings 11 can be hung on the hooks 18 on the headrest 17, and the headrest 17 can be deflected or tilted backward by stepping on the pedal 5. If the two pull rings 11 are respectively Hanging on the left and right hooks 18, the traction rope 10 will pull the headrest 17 to deflect left and right. If the two pull rings 11 are hung on the hook 18 in the middle, the traction rope 10 will pull the headrest 17 to lean back and perform "knee". neck training".

When the resistance of the pedal 5 is insufficient or the patient has the ability to use more force, the resistance can be increased by pulling the pull ring 11 by hand to improve the exercise effect.

When the patient's knee joint cannot exert force on its own and needs passive movement, the two horizontal bars 8 are installed, and the driving motor 13 is activated. The driving motor 13 drives the first gear 7 to rotate through the second gear 12, and the first gear 7 drives the two horizontal bars. When the rod 8 rotates, the two eccentrically installed transverse rods 8 drive the two pedals 5 to move up and down alternately through the two chutes 9, thereby driving the patient's legs to move up and down passively.

Beneficial effects of the present invention:

1. Patients do not need to bear their own weight;

2. The activities of the knee joint, shoulder joint and neck are linked, and the movement of the waist is also taken into account;

3. The exercises are "up the stairs", "sit down and stand up" and "lie down and sit up", which are the actions actually needed by middle-aged and elderly patients; the activities provided by their upper limbs are precise reverse arm movements. It is very helpful for the rehabilitation of shoulder arthritis. Some fitness equipment also provides arm rope resistance exercises, but the movements of the exercises are pulling, lifting, chest expansion and other actions that induce shoulder arthritis. The program uses multiple limiters to enable patients to only move the "reverse arm" movement that is not involved in normal labor, so as to avoid aggravating the disease and improve the recovery effect.

4. Flexible movement, can be one foot, two feet, one hand, both hands, both hands and feet, etc.

5. The function of motor-assisted movement is also provided for critically ill patients.
