Wound closure i.e. self adhesive wound closure, for wound dressing, has paste including water soluble chitosan slats, where paste is made of porous material, and specified range of chitosan mixed with specified range citric acid solution

摘要

The closure has a paste containing water soluble chitosan slats, where the paste is made up of porous material. 10 grams of chitosan with de-acetylation at a level of 60 percent is mixed with a solution of 200 grams of a citric acid in one liter of water until a complete dissolution is obtained. A small quantity of the calcium carbonate is observed without foam.
