Embodiment Construction

[0023] The medical transparent dressing of the present invention is formed by sequentially laminating a base layer, a transparent film layer, an adhesive layer and a non-adhesive layer. The base layer is made of polyethylene terephthalate film; the transparent film layer is made of polyamide coated on the base layer, and its thickness is not more than 100 microns; the adhesive layer is made of polyacrylate and polyamide The ester copolymer is coated on the non-stick layer; the non-stick layer is made of release paper. The total thickness of the entire film is not greater than 450 microns.

[0024] The preparation method of medical transparent dressing of the present invention is, at first used material is inspected, and the release paper that passes the inspection is coated on the rubber roller of gluing machine as non-stick layer; The adhesive formed by the copolymer is installed in a stainless steel tank, and the release paper is glued by the glue roller to form a uniform t...

Abstract

The present invention provides one kind of medical waterproof wound film and its making process. The medical waterproof wound film is one composite film including substrate layer, optionally permeating layer, adhesive layer and non-sticking layer superposed successively. The making process includes the steps of: painting the copolymer of acrylate and esteramide onto the non-sticking layer of strippable paper to form the adhesive layer, painting polyesteramide to the polyethylene terephthalate substrate to form optionally permeating layer, compounding the optionally permeating layer and the adhesive layer, etc. The medical waterproof wound film is waterproof, oxygen permeating to inhibit the growth of anaerobe and reduce infection, vapor permeable to maintain certain humidity and favorable to the growth of granulation tissue, and can promote the healing of wound.

Description

technical field [0001] The invention relates to a medical product and a manufacturing method thereof, in particular to a medical transparent dressing and a manufacturing method thereof. Background technique [0002] Medical transparent dressings are widely used in intravenous infusion care, various types of surgical towels, first and second degree decubitus care, first and second degree burn care, and various skin injury care. However, the medical transparent dressing of the prior art also has problems such as thicker thickness and insufficient air permeability, thus affecting its use effect. Contents of the invention [0003] The object of the present invention is to provide a medical transparent dressing with a new structure and a manufacturing method thereof, so as to improve the performance and use effect of the medical transparent dressing. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a medical transpa...
