Description

Fixing device for carpal tunnel syndrome

Technical Field

The utility model is suitable for a medical instrument technical field, more specifically relate to a fixing device for carpal tunnel syndrome.

Background

Carpal tunnel syndrome is the most common peripheral nerve entrapment of the upper limb, often significantly affecting the quality of life of the patient. The early carpal tunnel syndrome needs conservative treatment, wherein an important treatment means is to wear a wrist joint brace at night and keep the wrist joint in a neutral position or a slight dorsal extension position so as to avoid over-extension and over-flexion of the wrist joint, which leads to the increase of pressure in the carpal tunnel and further aggravates the clamping pressure of the median nerve. Currently, finished wristbands and custom wrist-fitted palm braces are commonly used and are constructed of low temperature thermoplastic material or lined metal panels to ensure the wrist joint is neutral. Although the existing brace can control the wrist joint to be in a neutral position or a slight dorsal extension position, the comfort of wearing of a patient is poor due to the high hardness of the material and the lining of the cotton pad, and the sleep of the patient is affected when the brace is worn at night, so that the brace is difficult to be worn for a long time and has high abandon rate. Many patients eventually require surgical treatment, greatly increasing the medical cost expenditure to society.

The carpal tunnel syndrome brace applied at present is a hard carpal palm support made of low-temperature thermoplastic material or lining metal plates. The wrist joint is fixed at the position of the wrist joint with neutral or slight dorsal extension mainly by a hard material placed on the palm side, but the metacarpophalangeal joint and the interphalangeal joint of the hand are not involved. Thus, the main disadvantages of the hard material carpometacarpal rest include the following:

1. the material is hard, and the comfort level is poor: although both the low temperature thermoplastic sheet and the metal sheet are lined with cotton to improve the comfort of wear. But because the hard material is hard, the wrist joint of the patient can not be jogged when wearing the wrist-.

2. The metacarpophalangeal and interphalangeal joints are not properly supported: when the wrist-palm support brace is worn, the metacarpophalangeal joints and the interphalangeal joints are not fixed, so that the brace is not supported. When sleeping, if the metacarpophalangeal joints and the proximal interphalangeal joints of the hand can give proper support on the palm side, the wearing comfort of the fixing device is obviously improved.

3. The night easily causes accidental injury: when sleeping, the human body is in an unconscious state, and the person or nearby persons can be injured by wearing the hard fixing device, so that the risk of accidental injury is increased.

SUMMERY OF THE UTILITY MODEL

Preferably, the length of the support body is the distance from the metacarpophalangeal joint of the adult to the middle part of the forearm, so that the support body has the required wrist joint fixing strength.

Preferably, the wrist sheath is in a fingerless glove shape, and the length of the wrist sheath is equal to that of the support body, so that the stability and comfort of the fixing device can be ensured.

Preferably, the wrist sheath extends towards the support body and forms a coating.

Preferably, the cover layer further comprises an opening for taking out the support body, and a zipper is arranged on the opening.

Preferably, the support body is made of a flexible material, preferably a high-density sponge, which has strength required for fixation and is relatively soft in material, so that the use comfort of a wearer can be improved; the coating comprises the cotton material, when improving the skin sense of touch, can also change and wash, has avoided peculiar smell such as sweat that long-term wearing leads to.

Compared with the prior art, the utility model discloses the beneficial effect who reaches:

1) the flexible material as the supporting and fixing material has the following required fixing strength: the thickness is preferably more than 2cm, the length from the metacarpophalangeal joint to the middle part of the forearm is flexible, the required wrist joint fixing strength is achieved, and meanwhile the fixing angle of the wrist joint can be changed according to the required wrist joint angle.

2) The supporting main body is made of flexible materials, so that the wearing comfort is remarkably improved: the texture of the flexible material is relatively soft, and meanwhile, the outer layer is lined with a coating layer made of cotton cloth, so that the comfort of skin contact is further improved.

3) Still be equipped with the coating outside the support main part, and preferably use the cotton material, when improving the skin sense of touch, can also change and wash, avoided peculiar smell such as sweat that wear for a long time and lead to.

4) Metacarpophalangeal and proximal interphalangeal joint support may be given: the free end of the palm part of the support main body is arc-shaped, and when the hand part is at a rest position, the palm side support can be used as the palm side support of the metacarpophalangeal joints and interphalangeal joints, so that the wearing comfort level at night is increased.

5) The wrist sheath is in a fingerless glove shape, and only the gap extending out of the thumb is exposed, so that the support is firmly and comfortably fixed.
