PROBLEM TO BE SOLVED: To provide a medical valve with a new structure which can prevent stagnation of a fluid such as a medicinal solution and improve durability of a valve body.SOLUTION: In arranging an elastic valve body 38 with respect to an opening member constituting an opening part of a fluid flow passage by locking locking protrusion parts 70, 80 on annular grooves 54, 56 provided on a peripheral portion of the disk-shaped elastic valve body 38, an inner circumferential side wall surface 60 of the annular groove 54 of the elastic valve body 38 is opposed to an inner circumferential surface 71 of a valve receiving seat 68 where the locking protrusion part 70 is formed with a gap in between in a radial direction, and the inner circumferential surface 71 of the valve receiving seat 68 abuts on and is superposed on the inner circumferential side wall surface 60 of the annular groove 54 of the elastic valve body 38 by inserting a male connector 104 into a slit 48 of the elastic valve body 38.COPYRIGHT: (C)2014,JPO&INPIT【課題】薬液等の流体の滞留を防止出来ると共に、弁体の耐久性が向上される、新規な構造の医療用弁を提供すること。【解決手段】ディスク形状の弾性弁体38の外周部分に設けた環状溝54,56に対して係止突部70,80を係止させることで、流体流路の開口部分を構成する開口部材に対して弾性弁体38を配設するに際して、係止突部70が形成された弁受座68の内周面71に対して弾性弁体38の環状溝54の内周側壁面60が径方向で隙間を隔てて対向されていると共に、雄コネクタ104が弾性弁体38のスリット48に差し入れられることにより、弁受座68の内周面71が、弾性弁体38の環状溝54の内周側壁面60に対して当接して重ね合わされるようにした。【選択図】図14
