Abstract
【解決手段】注射針本体2と、該注射針本体2の基端部を支持する基部3と、該基部3から左右両側方に突出して持ち手として機能する羽根部4とを備える羽根付き注射針1であって、羽根部4は、ヒンジ部4a、4b、4cを介して折り畳み自在な板状部材を用いて構成され、折り畳み状態では、基部3から左右両側方に突出して持ち手として機能する一方、展開状態では、基部3から注射針本体2に沿って注射針先端側に延出して注射針本体2を覆う安全カバーとして機能する。
【選択図】図1
Description
また、請求項1の発明によれば、羽根部の展開操作時に、注射針本体を羽根部に対して相対的に後退させる注射針後退手段を備えるので、安全カバー(羽根部)で覆うべき注射針本体の実質的な長さを短くすることができ、その結果、羽根部を安全カバーに兼用するにあたり、羽根部の大型化を回避できる。
また、請求項1の発明によれば、係合部の係合解除に応じて基部及び注射針本体をバネの付勢力で後退させるので、基部及び注射針本体の後退操作が不要になり、羽根部を安全カバーとして使用する際の操作が簡略になる。

Claims (1)
- 注射針本体と、該注射針本体の基端部を支持する基部と、該基部から左右両側方に突出して持ち手として機能する羽根部とを備える羽根付き注射針であって、
ヒンジ部を介して折り畳み自在な板状部材を用いて構成され、折り畳み状態では、基部から左右両側方に突出して持ち手として機能する一方、展開状態では、基部から注射針本体に沿って注射針先端側に延出して注射針本体を覆う安全カバーとして機能する羽根部と、
羽根部の展開操作時に、注射針本体を羽根部に対して後退させる注射針後退手段とを備え、
羽根部は、基部に外嵌する筒部と、筒部の前端部に第1ヒンジ部を介して折り曲げ自在に連結される第1板部と、該第1板部の先端部に第2ヒンジ部を介して折り曲げ自在に連結される第2板部と、該第2板部の先端部に第3ヒンジ部を介して折り曲げ自在に連結される先端板部とを備え、第1ヒンジ部を谷折り、第2ヒンジ部を山折り、第3ヒンジ部を谷折りとすることにより、第1板部及び第2板部が前後に重なり合った折り畳み状態で基部から左右両側方に突出して持ち手として機能する一方、すべてのヒンジ部を直線的に展開させた展開状態では、第1板部及び第2板部が基部から注射針本体に沿って注射針先端側に延出して注射針本体を覆う安全カバーとして機能し、
注射針後退手段は、羽根部の筒部で基部を後退方向にスライド自在に支持するスライド支持部と、基部を後退方向に付勢するバネと、基部を非後退位置に係合保持する係合部とを備え、該係合部の係合解除に応じて基部及び注射針本体を羽根部の筒部に対して後退させることを特徴とする羽根付き注射針。
