Claims (4)
- 内部に貫通孔が設けられることによって一端側に第1開口端および他端側に第2開口端が形成された筒状の本体部と、
前記第1開口端に着脱可能に取り付けられる有底筒状の栓部と、
前記本体部および前記栓部を接続する可撓性の接続部とを備え、
前記栓部は、前記第1開口端に取り付けられた取付状態において、前記第1開口端の外周面に遊嵌する側壁部と、前記本体部の軸線の延在方向に沿って前記第1開口端に対向する底部とを含み、
前記接続部は、前記栓部の前記側壁部に連結された第1固定端、前記本体部の外周面に連結された第2固定端、および、前記第1固定端と前記第2固定端との間に位置し、前記本体部から遠ざかる方向に向けて膨出する湾曲部を含み、
前記取付状態において、前記湾曲部を前記本体部の外周面に近づける方向に押し込んで伸長させることにより、前記栓部の前記側壁部と前記第1開口端の外周面との遊嵌が解除され、これにより前記栓部が前記第1開口端から取り外されるように構成されている、血液回路用コネクタ。 - 前記接続部は、前記第1固定端と前記湾曲部との間に位置し、前記取付状態において撓み変形することによって弾性力を発現する弾性力発現部をさらに含み、
前記栓部は、当該栓部の軸線が前記本体部の軸線と合致することとなるように前記弾性力発現部によって発現される弾性力に抗して回動することで前記第1開口端に取り付けられ、
前記栓部が取り外される際に、前記栓部の前記側壁部と前記第1開口端の外周面との遊嵌が解除されることにより、前記弾性力発現部によって発現される弾性力に基づいた復元力によって前記栓部が回動し、これにより前記本体部の軸線上から退避する、請求項1に記載の血液回路用コネクタ。 - 前記弾性力発現部が、略S字状の形状を有している、請求項2に記載の血液回路用コネクタ。
- 前記本体部、前記栓部および前記接続部が、射出成形によって一体成形されている、請求項1から3のいずれか1項に記載の血液回路用コネクタ。
