Description

Apparatus and system for preventing shoulder dislocation}

The present invention relates to shoulder dislocation prevention technology.

In general, the shoulder joint is a joint between the shoulder blade and the humerus and is also called the shoulder in a narrow sense. It is a key part.

The shoulder, which is composed of several joints, has the largest range of motion in our body and is the furthest away from the hand. Therefore, the shoulder functions to send the hand to a wide space, enabling various tasks. In particular, it plays a key role in sending the hand away from the body or behind the body or head. If such an abnormality occurs in the shoulder joint, the thrust required for work or exercise may be weakened or precise movement may become difficult.

On the other hand, when the shoulder joint is injured, usually, depending on the severity, cast with plaster or hang the arm with a shoulder strap or shoulder strap made of metal and plastic to cause sagging of the arm or subluxation of the shoulder joint due to the weight. to prevent the phenomenon.

However, when fixing the arm in this way, since the arm is kept in close contact with the body, if it is fixed for a long time, not only joint contracture, which stiffens the shoulder joint, but also the armpit or affected part adheres to a cast or orthosis This causes poor ventilation or impairs wound healing.

In general, the abduction angle of the shoulder joint has a great effect on treatment, and an angle of 40 to 50 degrees moves the humerus head to the scapula without straining the muscles or ligaments around the shoulder joint. It is possible to prevent dislocation by inserting it in a stable state, but when a support is used to maintain the angle, the center of gravity of the arm is located in the ulnar and ball head area on the inner side of the elbow, thereby compressing the nerves and blood vessels passing through this area. A problem arises.

When the angle of abduction is less than 40 degrees, the subluxation phenomenon occurs, and in the case of more than 60 degrees, the ligaments around the shoulder or the rotator cuff are overtense, resulting in an unstable posture. Therefore, it is very important to select an appropriate support for children, adults, and size.

On the other hand, recently, convergence technology ideas due to the 4th industrial revolution are attracting attention. As a result, they are keen to develop products to improve the quality of human healthy life, and the market size using medical instruments for traumatic diseases is rapidly increasing. And, in the sense of a medical device, it is not a device used by doctors in its own form, but by grafting a convergence technology called a healthcare device, it insists on a function that allows anyone to self-diagnose the condition of the body.

As an orthosis for habitual shoulder dislocation that is currently in circulation, a support brace using a sponge and banding and a passive rehabilitation device with gear control are mostly used. This prior art has a problem that the patient himself has to carry a support cushion, and that frequent pressure and burden are applied to the opposite shoulder and neck cervical vertebrae due to many banding connection parts, which complains of discomfort. In addition, the device with a built-in gear has a problem in that it is difficult for the patient to directly adjust the weight and gear because it is difficult to adjust the weight.
