PROBLEM TO BE SOLVED: To provide a line connection connector for medical treatment, a line connection connector that is defined as a novel structure and is capable of preventing as much as possible various germs from entering into a fluid line from outside through a needle tube which is penetratingly stabbed in an elastic seal of a port.SOLUTION: A line connection connector 10 is structured such that a needle tube 16 is projectingly provided in one opening of a penetration hole 14 in a needle hub 12, that a port part 18 for line connection is formed in the other opening of the needle hub 12, with a needle protection hood 24 covering the outer periphery of the needle tube 16 also provided, and that the connector 10 is connected to a fluid line 138 by stabbing the needle hub 12 in an elastic seal 114 provided in the fluid line 138. In this connector 10, the needle tube 16 is covered with an elastic cover 52, whose opening 54 on the proximal end side is hermetically attached to the proximal end side of the needle tube 16. Consequently, the tip end part of the needle tube 16 stabbed in the elastic seal 114 is covered with the elastic cover 52.COPYRIGHT: (C)2016,JPO&INPIT【課題】ポートの弾性シールに貫通穿刺される針管を介して外部から流体ライン内へ雑菌等が入り込むことを可及的に防止することのできる、新規な構造とされた医療用のライン接続コネクタを提供する。【解決手段】針ハブ１２における貫通孔１４の一方の開口部に針管１６が突設されていると共に、該針ハブ１２の他方の開口部にライン接続用のポート部１８が形成されている一方、該針管１６の外周を覆う針保護フード２４が設けられており、流体ライン１３８に設けられた弾性シール１１４に対して該針ハブ１２を穿刺することで該流体ライン１３８へ接続される医療用のライン接続コネクタ１０において、前記針管１６に弾性カバー５２が被せられて、該弾性カバー５２の基端側開口部５４が該針管１６の基端側に対して気密に装着されることにより、前記弾性シール１１４へ穿刺される該針管１６の先端部分が該弾性カバー５２で覆われている。【選択図】図１
