PROBLEM TO BE SOLVED: To provide a medical port that allows a sealing part for sealing a connection port of a tube for collecting liquid to be changed easily while keeping the connection port of the tube for collecting liquid clean.SOLUTION: A medical port 1 disposed in a line where liquid circulates includes an inner cylinder part 3, a body part 4 in which a cylindrical inner cylinder accommodation part 41 for accommodating the inner cylinder part 3 is formed between itself and the outer periphery of the inner cylinder part 3, an outer periphery wall part 6 which protrudes from the surrounding of the inner cylinder accommodation part 41 in the body part 4 in an extending direction of the inner cylinder part 3, and in which an opening 61 is formed at the tip, and a lid member 7 detachably attached to the outer periphery wall part 6. The lid member 7 includes a lid body 71 and a slide member 72 detachably attached to the lid body 71 by the sliding of the inner cylinder part 3 in a direction intersecting with the extending direction with respect to the lid body 71. The slide member 72 includes a sealing part 76 for sealing the opening 61 and a holding part 73 for holding the sealing part 76.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2019,JPO&INPIT【課題】液体を採取するためのチューブの接続口を清潔に保ちつつ、液体を採取するためのチューブの接続口を密閉する密閉用部分を容易に交換できる医療用ポートを提供すること。【解決手段】液体が流通するラインに配置される医療用ポート1であって、内筒部3と、内筒部3の外周との間に内筒部3を収容する筒状の内筒収容部41が形成された本体部4と、本体部4における内筒収容部41の周囲から内筒部3の延びる方向に突出すると共に先端部に開口61が形成された外周壁部6と、外周壁部6に着脱可能に取り付けられる蓋部材7と、を備え、蓋部材7は、蓋本体71と、蓋本体71に対して内筒部3が延びる方向に交差する方向にスライドすることで蓋本体71に着脱可能に取り付けられるスライド部材72と、を有し、スライド部材72は、開口61を密閉する密閉用部分76と、密閉用部分76を保持する保持部分73と、を有する。【選択図】図8
