Description
Claims (1)
- 前端が鋭利な針管と、針管の後端部を支持し、後端に可撓性チューブを接続する接続管部が設けられたハブとから成る針本体と、針本体を収納可能な筒状のプロテクタと、プロテクタに内蔵され、針本体をプロテクタに対し後方に付勢するばね部材と、針本体を針管がプロテクタの前端から突出する使用位置にばね部材の付勢力に抗して係止自在な係止手段とを備え、係止手段による係止を解除することで針本体がばね部材の付勢力で後方に移動して、針管の前端がプロテクタ内に没入されるようにしたプロテクタ付き医療用針において、
接続管部に可撓性チューブの前端部を外嵌接続した状態で、接続管部の基部外周に可撓性チューブの前端面による径方向外方への段差が形成されるようにし、
プロテクタの後端に、自由状態での内径が段差の外径より小さな環状のストッパ部が設けられ、接続管部に外嵌する可撓性チューブの前端部を、該前端部とストッパ部との少なくとも一方を弾性変形させつつ、ストッパ部の後方に引抜き自在とし、
ストッパ部に後方から段差が当接した状態で針管の前端がプロテクタの前端から突出しないように、針本体及びプロテクタの長さが設定されていて、
前記ハブの前記接続管部より前方部分に、径方向外方に膨出するフランジ部が形成され、前記プロテクタの内周の後端寄りの部分に、フランジ部が圧入自在な小径部が形成されると共に、小径部の前方から小径部に向けて次第に縮径するテーパー部が形成されていることを特徴とするプロテクタ付き医療用針。
