Abstract:
A hyaluronic acid and a carboxy methyl cellulose composite derivative film is provided to have trachea reducing adhesion property, excellent biodegradation property and property absorbed by being completely disassembled after preventing adhesion phenomenon. An N-acylation urea pendant form and an auto-cross-linking form are mixed in hyaluronic acid and carboxy methyl cellulose composite derivative film. The N-acylation urea pendant form and an auto-cross-linking form are made by reacting crosslink activity agent and cross linkage activity supplement at hyaluronic acid and carboxy methyl cellulose complex film surface. The derivative film with the N-acylation urea pendant form is formed by using the crosslink activity agent 0.01 ~ 500 parts by weight and the cross linkage activity supplement 0.01 ~ 200 parts by weight based on compound of the carboxy methyl cellulose and hyaluronic acid 100 parts by weight. The derivative film with the auto-cross-linking form is formed by using the crosslink activity agent 0.01 ~ 500 parts by weight and the cross linkage activity supplement 40 ~ 1000 parts by weight.
