Embodiment Construction

[0017] Specific implementations of the band-aid and plaster of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] figure 1 It is the structural representation of the band-aid of the present invention. The band-aid of the present invention at least includes two layers of an outer layer 1 and an inner layer 2, and the outer layer 1 and the inner layer 2 are pasted together, wherein the inner layer 2 is made of a textile material containing natural marine polymer chitosan fibers (hereinafter referred to as marine biological fiber material); the outer layer 1 is made of microporous polytetrafluoroethylene membrane material (hereinafter referred to as ePTFE membrane material). The thickness of the ePTFE membrane material is 20-70 μm. 3 is a surface layer, which can be a decorative layer or a protective layer to protect the ePTFE membrane material on the inside from damage. The textile material containing natural marine h...

Abstract

The present invention relates to an adhesive plaster for treating wound. It is characterized by that it includes two layers of inner layer and outer layer, the described inner layer and outer layer are adhered into one whole body, its inner layer is made up by using fabric material containing natural marine high-polymer chitoamine fibre and its outer layer is made up by using microporous teflon film material. Said adhesive plaster has the functions of resisting bacteria, relieving inflammation, arresting bleeding, promoting wound healing and promoting tissue growth, etc.

Description

technical field [0001] The invention relates to a band-aid and a plaster, in particular to a band-aid and a plaster which are waterproof and have good air permeability. Background technique [0002] Ordinary band-aids and plasters are not waterproof, have no air permeability, and are extremely uncomfortable to cover on the skin, especially when the wound occurs on the hand and other parts that are often wet, the band-aid must be replaced frequently, or the surrounding area of ​​the wound turns white , so that the wound can not heal for a long time. [0003] The background information of the raw materials used in the present invention will be introduced below. Chitin fibers come from the shells of shrimps, crabs, and shellfish. The annual output of shells in the ocean reaches 1 billion tons, and the output of natural polymers is second only to cellulose. Chitin is a natural polysaccharide substance, because it has a good crystalline structure and more hydrogen bonds, so its...
