PROBLEM TO BE SOLVED: To provide a medical port in which the occurrence of liquid leakage is suppressed.SOLUTION: The medical port includes a disc-shaped valve 1 having an insertion hole formed in a center section 1a, a base seat 7 for carrying the valve 1 from the lower surface side, and a cover 2 having a fitting hole which exposes the upper surface of the center section of the valve 1 and covering at least the peripheral edge of the valve 1 from the upper surface side of the valve. The fitting hole is configured such that, when an inserting body is inserted in the insertion hole, the inserting body and the fitting hole are suitable for each other to engage the inserting body with the cover 2. A circumferentially continuous annular projection 1d is formed on the valve 1 so as to make contact with the outer peripheral surface of the chip of the inserting body when the inserting body is engaged with the cover 2.COPYRIGHT: (C)2010,JPO&INPIT【課題】液漏れの発生が抑制された医療用ポートを提供する。【解決手段】中央部1aに挿入孔が形成されたディスク状の弁1と、弁を下面側から担持する台座7と、弁の中央部における上面を露出させる嵌合孔を有し、かつ、少なくとも弁の周縁を上面側から覆うカバー2と、を含み、挿入体が挿入孔へ挿入されたときに、挿入体と嵌合孔との嵌合により挿入体をカバーに係止させうるように、嵌合孔が形成された、医療用ポートであって、弁1に環状凸部が形成されており、周方向に連続した環状凸部が形成されており、挿入体をカバーに係止させた状態のときに、環状凸部が前記挿入体の先端部外周面に接するように、弁1に環状凸部1dが形成された医療用ポート。【選択図】図8
