Embodiment Construction

[0020] In order to describe the structure, features and effects of the present invention in detail, the following preferred embodiments are given below and described with reference to the accompanying drawings.

[0021] Such as figure 1 Shown is the first preferred embodiment of the wound cover 1 of the present invention, which is used to cover a wound (not shown in the figure). The wound cover 1 includes a fabric layer 11 and an adsorption layer 12 .

[0022] The fabric layer 11 is used to contact the wound and is woven from polyacrylonitrile activated carbon fibers. The manufacturing steps are: 1. Provide a polyacrylonitrile oxidized fiber fabric; 2. Use water-containing carbon dioxide gas as the activation gas; The acrylonitrile oxidized fiber fabric is heated to 700-1200°C in a high-temperature furnace, and activated gas is introduced, and maintained for 1 minute to 1 hour to form a polyacrylonitrile activated carbon fiber fabric, which is cut into an appropriate size to f...

Abstract

The invention relates to a wound covering which is used for covering a wound, and is characterized by comprising a fabric layer and an adsorption layer, wherein the fabric layer is formed by weaving polyacrylonitrile activated carbon fibers; the activated carbon fibers of the fabric layer are formed in a manner that polyacrylonitrile oxidized fibers are maintained in hydrous carbon dioxide at 700-1200 DEG C for 1-60min; the adsorption layer is arranged on one side, far away from the wound, of the fabric layer, and is made of one or a combination of a super absorbent polymer, cotton, alginate, polyvinyl alcohol and PU (Poly Urethane) foam; and the adsorption layer has higher water adsorption capacity than the fabric layer. The fabric layer of the wound covering cannot generate dust, and can be kept in a dry state, so that the problem that the wound is not easy to heal can be solved effectively.

Description

technical field [0001] The invention relates to a wound covering, in particular to a wound covering composed of a fabric layer and an adsorption layer. Background technique [0002] In the medical field, activated carbon materials are often used in wound coverings due to their better absorbency than traditional medical gauze. However, the activated carbon fabric made of pitch or lignin with the current technology cannot avoid the generation of activated carbon dust, and if it accidentally falls into the wound, it will cause difficulty in wound healing. [0003] In addition, although the above-mentioned activated carbon material has a strong absorption capacity, when the tissue fluid produced by the wound is too much or the new product is not replaced in time, the wound cover that absorbs the tissue fluid and reaches a saturated state may cause the wound to be too moist, thus affecting the healing of the wound. have negative impacts. Contents of the invention [0004] In ...
