Description
Claims (3)
- 医療用チューブを接続する中空のコネクタ本体と、コネクタ本体の外周に設けられた、注射器の口部を挿入するための挿入ポートとを備え、挿入ポート内には外気を遮断するための弾性材料で形成された板状のバルブが設けられ、バルブにはスリットが形成され、注射器の口部を挿入ポートに挿入する際には、該口部によりスリットが押し開かれて、挿入ポート内に口部が挿入されるようにした医療用コネクタにおいて、
前記挿入ポート内には、弾性材料で形成されたブシュが嵌着され、挿入ポートの開口端側のブシュの端部を塞ぐようにして前記バルブがブシュと一体に形成され、
該ブシュの内周は、前記注射器の口部を前記挿入ポートに挿入することによって押し開かれる前記スリットの両脇のバルブの部分を受け入れる大径穴部と、前記挿入ポート内に挿入された注射器の口部が液密に嵌合して保持される、大径穴部からコネクタ本体側にのびる、大径穴部より内径が小さい小径穴部とを有する段付き穴形状に形成されることを特徴とする医療用コネクタ。 - 前記挿入ポートの開口端部寄りの部分は、内周面が開口端側に向かって縮径するテーパー形状であることを特徴とする請求項1記載の医療用コネクタ。
- 前記挿入ポート内に、前記ブシュの前記コネクタ本体側の端面とコネクタ本体との間に位置させて、前記コネクタ本体内を流れる流体が前記ブシュの内周に流れ込むことを阻止する逆止弁を設けることを特徴とする請求項1又は2記載のコネクタ。
