Description

Medical arm protective sleeve formed by shape memory warp knitting and production process thereof
Technical Field
The invention relates to a medical arm protective sleeve formed by shape memory warp knitting and a production process thereof, belonging to the technical field of textile medical use.
Background
Medical supplies are a generic term for articles used for treating wounds or for treating diseases. When the arm of the human body is wounded, the arm is often wrapped by medical dressing, and the dressing is fixed by medical adhesive tape. Most people in real life often cause the pollution and the falling of the dressing due to frequent use of the arm, and particularly in hot summer, the adhesion between the medical adhesive tape and the arm can be damaged due to the secretion of sweat, so that the falling of the dressing is accelerated, and the wound surface cannot be effectively treated and protected. For some people with sensitive skin, the medical adhesive tape can also bring about the trouble of itching and allergy of the arms.
In order to fix and protect wound dressing, there are some simple and easy protection arm protective sheaths on the market, use polyurethane fiber for the protective sheath mostly to provide the constraint power, though can protect arm wound position, but also because the dimension of human arm changes ten thousand, even the product has set up conventional size scope, nevertheless can lead to the pressure too big because the mismatch of constraint power and human arm size, not only influences the healing of wound, still can reduce the travelling comfort. Therefore, it is necessary to develop a medical external fixation material with simple operation, good performance and high comfort.
In addition, the vein indwelling needle is composed of a stainless steel core, a soft outer sleeve and a plastic needle seat, the outer sleeve and the needle core are punctured into the blood vessel during puncture, after the sleeve is sent into the blood vessel, the needle core is drawn out, and only the soft outer sleeve is left in the blood vessel for transfusion; when the venous indwelling needle is arranged on the arm of the patient, the arm of the patient cannot move disorderly, once the venous indwelling needle is disorderly, the blood vessel wall is easy to puncture, and the venous indwelling needle is easy to be pressed by the other hand of the patient during sleep, so that the venous indwelling needle falls off; it can be seen that control of the venous indwelling needle is critical; moreover, the venous indwelling needle needs corresponding holes of medical external fixing materials to correspond to the holes, otherwise, the venous indwelling needle cannot be fixed at all; the requirements for medical external fixation materials are also higher.
