A WOUND-HEALING DRESSING PATCH WITH HYDROGEL LAYER CONTAINING CHITOSAN

摘要

A chitosan hydrogel patch for healing a wound is provided to heal the wound smoothly and promptly by forming a moisturizing environment by the absorbent function of water soluble chitosan. A chitosan hydrogel patch for healing a wound includes a release film(1) or a release sheet(2), a hydrogel pad(8) and an adhesive polyurethane film(a,b). The release film or the release sheet prevents the pollution from the outside. The hydrogel pad is made by laminating a hydrogel layer on a supporting body. The hydrogel layer contains chitosan that has a function of healing a wound and absorbing exudation as a principal component. The polyurethane film having a waterproof function is bonded to a cutting support body to fix the hydrogel to the wound and is attached to the user's skin.
