Title:
MANUFACTURING METHOD OF MEDICAL USE TREATMENT MATERIAL
Document Type and Number:
Japanese Patent JP2023029055
Kind Code:
A
Abstract:
To provide a manufacturing method of a medical use treatment material having a physical crosslinking structure due to a hydrogen bond, and capable of guaranteeing sterility while suppressing a shape change and property change before and after sterilization treatment, in a medical use treatment material that has a physical crosslinking structure due to a hydrogen bond and forms hydrogel due to contact with a water content.SOLUTION: A medical use treatment material forming hydrogel by contact with a water content is manufactured according to a method comprising obtaining a film-like solid containing one polymer among a polymer (A) having a structural unit derived from an ethylenically unsaturated monomer having a carboxyl group, and a polymer (B) having a structural unit derived from an ethylenically unsaturated monomer having a functional group capable of forming a hydrogen bond with the carboxyl group (where the polymer (A) is omitted), drying after contacting the film-like solid and a polymer solution containing the other polymer of the polymer (A) and the polymer (B), and sterilizing a dried body by radiation sterilization.SELECTED DRAWING: None
