Document Type and Number:
WIPO Patent Application WO/2019/163764
Kind Code:
A1
Abstract:
The present invention provides a medical instrument exhibiting excellent lubricity and durability (maintenance of lubrication). The present invention relates to a medical instrument having: a substrate layer; an adhesive layer which is formed on at least a portion of the substrate layer and which includes a hydrophilic copolymer including constituent units derived from a polymerizable monomer (A) having a sulfobetaine structure, constituent units derived from a polymerizable monomer (B) having at least one group selected from the group consisting of a sulfonic acid group (-SO3H), a sulfuric acid group (-OSO3H), a sulfurous acid group (-OSO2H), and salts thereof, and constituent units derived from a polymerizable monomer (C) having a photoreactive group; and a surface lubrication layer which is formed on at least a portion of the adhesive layer and which includes a hydrophilic polymer that is dissolvable in a solvent capable of dissolving or swelling the hydrophilic copolymer.
