PROBLEM TO BE SOLVED: To be easy to mount, to have a reduced burden on the body after mounting, and to have excellent stability.SOLUTION: A penetration-inhibiting member is provided with a tubular mounting section 104 that is fitted on a circumferential surface of a tube 101 to be inserted into a body, and a penetration-inhibiting section 105 that is integrated with the mounting section 104 and restricts a penetration distance of the tube 101 into the body. The mounting section 104 is provided with a guide section for guiding an insertion port of a body side into which the tube 101 is inserted. The penetration-inhibiting section 105 extends radially from the mounting section 104 and is made of multiple elastic penetration-inhibiting pieces 104a, 105a.SELECTED DRAWING: Figure 10COPYRIGHT: (C)2017,JPO&INPIT【課題】装着容易で、装着後の身体への負担が少なく、安定性に優れた構成とする。【解決手段】体内に挿入されるチューブ101の外周面に装着される筒状の装着部104と、装着部104に一体化され、チューブ101が体内に進入する寸法を制限する進入阻止部105と、を備える。装着部104は、チューブ101が挿入される身体側の挿入口をガイドするガイド部を備える。進入阻止部105は、装着部104から放射状に延び、弾性を有する複数の進入阻止片104a,105aからなる。【選択図】図10
