PROBLEM TO BE SOLVED: To enable implementation of a medical connector capable of reducing discomfort at the time of its touching a skin as well as improving operability.SOLUTION: A medical connector comprises: a cylindrical connector connection part 101 to which a connector to be paired with the part is to be connected a tube connection part 102 provided closer to a base end than the connector connection part 101 a flange part 103 provided on a base of the connector connection part 101 and alar parts 104 provided closer to the base end than the flange part 103, the alar parts protruding from the tube connection part 102 in both lateral directions. The flange part 103s planar shape is oval or elliptic. The flange part 103s major axis is longer than the outer diameter of a lock ring of the connector to be paired the flange part 103s minor axis has a length agreeing with that of the outer diameter of the base of the connector connection part 101. The alar parts 104 extend in a direction of the flange part 103s major axis. The maximum width between the alar parts 104 is equal to or shorter than the length of the flange part 103s major axis.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】皮膚に触れた際の違和感を低減できると共に、操作性を向上させることができる医療用コネクタを実現できるようにする。【解決手段】医療用コネクタは、対となるコネクタが接続される円筒形状のコネクタ接続部101と、コネクタ接続部101よりも基端側に設けられたチューブ接続部102と、コネクタ接続部101の基端に設けられた鍔部103と、鍔部103よりも基端側においてチューブ接続部102の両側方に突出した翼部104とを備えている。鍔部103は、平面形状が長円形状又は楕円形状であり、鍔部103の長径は、対となるコネクタのロックリングの外径よりも大きく、鍔部103の短径は、コネクタ接続部101の基端の外径と一致している。翼部104は、鍔部103の長径の方向に拡がり、翼部104の翼間の最大幅は鍔部103の長径以下である。【選択図】図1
