A WOUND DRESSING SUBSTANCE WITH DISCOLORING FUNCTION AND ITS MANUFACTURING METHOD

摘要

The present invention relates to a color-changed dressing substance and a manufacturing method thereof and, more specifically, to a color-changed dressing substance and a manufacturing method thereof, capable of forming a dressing substance, attached to a wound such as a cut or a burn, to chage colors when reacting to moisture. When a lot of an exudation is absorbed by the dressing substance, the dressing substance can change the color into a specific color. Therefore, a user can easily grasp a replacement time for the dressing substance. The dressing substace includes a film layer formed at a fixed thickness by mixing foaming resin, methyl ethyl ketone, and dimethylformamide; a color-changed absorption foam layer formed at a fixed thickness by mixing a foamed resin prepolymer, foam compositions, and a water discoloration article; and a wound contact absorption form layer formed at a fixed thickness by mixing foamed resin prepolymers, and foamed composition.
