摘要

PROBLEM TO BE SOLVED: To provide an elastic membrane having a function of reactivating an endometrium base layer in a uterine cavity and a method for producing the same. SOLUTION: A drug containing silicon rubber and at least one kind of estrogen is wrapped in or uniformly dispersed inside the silicon rubber as a drug storage region, or is supported on the outer surface of the silicon rubber as a coating layer. Drugs and. A matrix-type elastic film is formed by mixing silicone rubber and a drug and vulcanizing and cross-linking to cure the silicone rubber and the drug into a mixed film, or a chemical solution is formed by dissolving the drug and a degradable polymer in a solvent. Then, the slow-release coating layer is formed by spray-coating the chemical solution on the silicone rubber. [Selection diagram] FIG. 14
