Description

The present invention relates to a shoulder pain relieving brace for the shoulder joint cuff tear patient.

  Usually, a person who has torn or damaged a shoulder joint rotator cuff will experience extreme shoulder pain. It is known that shoulder pain appears prominently at night as well as during daily sitting and walking, and disturbs sleep.

  In order to solve these problems, various appliances or treatment instruments have been proposed, but generally there are shoulder pillows that have been used for a long time. Such a shoulder pillow exclusively uses the cushion function, and a great effect cannot be obtained.

Further, various proposals have been made as an effective device for reducing shoulder pain. For example, the following techniques can be cited.
JP2007-37710A.

  According to the above cited reference 1, the cause of shoulder pain at night is investigated, and in the supine position, gravity acts on the shoulder joint, the patient's shoulder hangs down and the shoulder joint extends and contracts. It is considered that the cause is forced.

  Therefore, as a countermeasure, consider putting a block-shaped member on the underside of the shoulder when supine to prevent the shoulder joint from drooping, and even if such a block-shaped member rolls over, it comes off the shoulder. In order to prevent this, it is fixed to the shoulder covering member.

With these braces, it has become possible to expect an effective shoulder pain reduction effect that could not be obtained with conventional shoulder pillows aimed solely at the cushion effect, but the subject was a person who had torn or damaged the shoulder joint rotator cuff It seems that the purpose was relatively achieved.
It was reported that when this brace was performed on a patient who had a rotator cuff suture operation, the shoulder pain at night (noon) was not reduced as much as expected.

There are two modes for this situation: patients with shoulder joint rotator cuff injury can be broadly divided into cases in which the damage or tear remains intact, and rotator cuff sutures are performed by surgery, followed by rehabilitation. It is thought that this is due to the difference in the mechanism of shoulder pain in each state.
In other words, it is speculated that when the rotator cuff is sutured by surgery, the rotator cuff becomes shorter than before, and the relative position of the shoulder and arm in the shoulder joint changes in the natural state (muscle relaxed state). That is, it is considered that the horizontal bending of the shoulder joint is in a natural state rather than being in a state different from that of a healthy person.

When the rotator cuff is sutured in this manner, the relative position between the shoulder and the arm in the shoulder joint changes, and as a result of the horizontal flexion of the shoulder joint, the degree of drooping of the shoulder joint increases. Can be assumed. If the shoulder joint droops in this way, if it is simply to suppress the drooping of the shoulder joint, it can be easily handled by changing the position or size of the block-shaped member described above. Yes, and it has actually been done that way.
However, in fact, this treatment did not significantly improve shoulder pain.

In view of the above problems, and an object thereof is to make possible to effectively reduce the shoulder joint cuff tears patient's shoulders pain.

Shoulder pain relieving orthosis according to the present invention, in order to solve the above problems, as described in claim 1, a shoulder pain relieving brace for the shoulder joint cuff tear patient,
A body member (1) positioned between the upper arm and the body side so as to relax the rotator cuff while holding the upper arm at a predetermined abduction angle;
Attachment means (2) for attaching the body member (1) to the body;
The upper arm holding member (4) which is wound around the upper arm and has locking means (3) ,
The main body member (1) is configured in a bag shape and includes a filling member (11) whose volume can be changed inside. The filling member (11) is configured by an airbag including a cap (11A). It is configured so that the volume can be changed according to the filling amount,
