- 液体流路に接続される開口部材にディスク状の弾性弁体が装着されており、該弾性弁体の外周部分に形成された薄肉部が該開口部材の内側と外側の爪部で挟まれると共に、該弾性弁体の該薄肉部よりも外周側が該開口部材で保持されることにより、該弾性弁体の外周部分が該開口部材で支持されて、該弾性弁体の中央部分に設けられたスリットに雄コネクタを繰り返し挿抜可能とされた医療用弁において、
前記薄肉部が、前記中央部分の外周側において前記弾性弁体の軸方向で該中央部分と重なる位置に設けられていると共に、該弾性弁体の内側面における該薄肉部の内周側を周方向に延びる周溝が、該薄肉部の底面より大きな深さで形成されていることを特徴とする医療用弁。 - 前記弾性弁体における前記周溝の外周側の壁部の肉厚寸法が、前記薄肉部の肉厚寸法より厚くされている請求項1に記載の医療用弁。
- 前記周溝の外周側の壁面が内方に向かって拡開する方向に傾斜している請求項1又は2に記載の医療用弁。
- 前記周溝が前記薄肉部に沿って周方向で円周状に延びている請求項1〜3の何れか1項に記載の医療用弁。
- 前記周溝が切込状のスリットとされている請求項1〜4の何れか1項に記載の医療用弁。
