PROBLEM TO BE SOLVED: To provide a method for producing a medical supply having a lubrication layer (coating layer) that exhibits excellent durability (particularly, slide durability).SOLUTION: The present invention relates to a method for producing a medical supply having a substrate layer, and a lubrication layer supported on at least part of the substrate layer. The method includes coating the substrate layer with a solution containing a block copolymer having a hydrophobic monomer-derived constitutional unit (A) and a hydrophilic monomer-derived constitutional unit (B), a carboxylic acid compound with a molecular weight of 80 or more to less than 1,000, and a solvent.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】優れた耐久性(特に、摺動耐久性)を発揮する潤滑層(被覆層)を有する医療用具の製造方法を提供する。【解決手段】本発明の医療用具の製造方法は、基材層と、前記基材層の少なくとも一部に担持された潤滑層と、を備える医療用具の製造方法であって、疎水性単量体由来の構成単位(A)および親水性単量体由来の構成単位(B)を有するブロック共重合体と、分子量が80以上1,000未満であるカルボン酸化合物と、溶媒と、を含む溶液を前記基材層上に塗布することを含む。【選択図】なし
