Medical application and fixation adhesive tape

Abstract

The invention discloses a medical application and fixation adhesive tape which comprises a silica gel layer in the bottom layer and a polyurethane membrane layer covering the silica gel layer; a connecting layer of a netty structure is also arranged between the silica gel layer and the polyurethane membrane layer. A silica gel penetrates into gaps formed by the connecting layer of the netty structure, so that the silica gel layer forms a whole body taking the connecting layer of the netty structure as a framework, and therefore, the silica gel is unlikely to fall locally. A photocatalyst sterilizing layer is coated to the edge of the outer surface of the silica gel layer. The photocatalyst sterilizing layer contains the following raw materials in parts by weight: 5-9 parts of nano titanium dioxide, 7-10 parts of nano silicon dioxide, 5-11 parts of carbon fiber particles and 20-25 parts of vegetable gelatin. The photocatalyst sterilizing layer is prepared by uniformly mixing the raw materials in proportion. According to the medical application and fixation adhesive tape, double propagation of anaerobic bacteria and aerobic bacteria at the edge of the medical adhesive tape can be effectively inhibited, so that infection in wounds can be effectively avoided.

Description

technical field [0001] The invention relates to the field of adhesive tapes, in particular to a medical sticking and fixing adhesive tape. Background technique [0002] At present, medical adhesive tapes, such as band-aids or wound pads, etc., are applied to the skin as a fixed wound or dressing. The adhesive tape part is mainly coated with glue on one side of the carrier layer so that it can be attached to the skin. to fix. Although the tape can be attached to the skin to achieve the purpose of fixing and protecting, but because the adhesive tape is not easy to breathe, it will cause redness, itching, and allergies, and if the tape is soaked with water or sweat, The moisture or sweat on the skin is not easy to disperse, but impregnated on the skin surface, not only the adhesive force is reduced, the tape is easy to fall off, what's more, the skin becomes white and wrinkled due to long-term soaking, and it is easier to breed bacteria and inflame the wound not easy to heal;...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a medical sticking adhesive tape, which solves the defects of the existing adhesive tapes. It is non-toxic and non-irritating to the skin, has good waterproof and air permeability, and is firm and comfortable for sticking and fixing. It is gentle and soft to peel off without pain.
