PROBLEM TO BE SOLVED: To provide a resin-made medical device, the surface of which is marked, in an easily visible manner, with product information that is never removed even when wiping with alcohol or disinfection and cleaning using high temperature and high pressure are carried out, also to provide an information marking method for the resin-made medical device.SOLUTION: A resin-made medical device according to the present invention comprises: a device body (ball trial 1) that is a resin molding and a product information-marked portion M formed by a permeable ink penetrated into a surface of the device body. The product information-marked portion M can clearly indicate information about the product with an enhanced appearance, compared with conventional products which bear product information by engraving, stamping, or other methods. In addition, the information marked on the device is never removed by wiping with alcohol, disinfection, and cleaning regularly carried out in hospitals or the like, so reuse (recycling) of the device after disinfection and cleaning can be performed multiple times.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】アルコール拭きや高温・高圧による殺菌洗浄を行っても消えることのない製品情報が、製品表面に見え易く表示された樹脂製医療用器具および樹脂製医療用器具の情報表示方法を提供する。【解決手段】本発明の樹脂製医療用器具は、樹脂の成形体からなる器具本体(ボールトライアル1)と、該器具本体の表面に浸透された、浸透性インクからなる製品情報表示部Mと、を備える。前記製品情報表示部Mは、製品情報を彫刻や刻印等により表示した従来品に比べ、これら製品に関連する情報を、見栄え良く、はっきりと表示することができる。しかも、病院等で常用される、アルコール拭きや殺菌洗浄を行っても消えることがないため、この器具を殺菌洗浄等して行う再利用(再生)を、複数回にわたり行うことができる。【選択図】図1
