Abstract
【解決手段】 カニューレ11の基部に連結され内部にカニューレ11の内腔11aに連通する空間部が設けられた外針本体12の内部にコネクタ部15を移動可能な状態で設けた。そして、コネクタ部15の先端側部分を液密的に通してカニューレ11の内腔11aとコネクタ部15の流路とを連通させることができるとともにコネクタ部15の先端側部分が挿通していないときには閉塞して外針本体12の空間部の前部側と後部側とを遮断する開閉孔14aを備えた弁体14を、外針本体12内に設けた。さらに、コネクタ部15の先端側部分が挿通できる挿通穴13aを備えた弁体押さえ板13を弁体14の後面側に設け、弁体押さえ板13と、コネクタ部15に形成されたばね受け部15cとの間にコイルばね16を設置した。
【選択図】 図4
Description
弁体押さえ板13が設けられ、筒状収容部12aの空間部17bにおける弁体押さえ板13の前部側に弁体14が設置されている。また、筒状連結部12bの内部には、コネクタ部15が筒状連結部12bの軸方向に移動可能な状態で設置されている。弁体押さえ板13は、リング状の円板で構成されており、図5に示したように、中央に弁体14を介して筒状収容部12a内の空間部17bの前部側部分とコネクタ部15内の流路とを連通させる挿通穴13aが形成されている。
