Abstract
Description
るロッキングガイドは、内針が挿入される中空の位置が変更されたり、中空の構造が変更されたりすることにより、内針の経路を一回性のものに実現する。
る。バネ13は、スライドケース30の内部に引き込まれ、弾性力を用いてスライドケース30を最後まで押し上げる。これにより、使用者の手動による操作なしにも内針110のロッキングガイド部5の離脱が保証される。初期のバネ13の固定は、ハブ305の締結部307(図11)により実現可能である。
Claims (5)
- 外針が設けられたカテーテルハブと、
前記カテーテルハブに挿通される内針が設けられて前記外針を血管内に留置し、前記カテーテルハブから取り外されるカニューレプラグと、
前記内針が貫通される中空部が形成され、貫通された前記内針の引き出しの際に前記中空部の位置が変更されて前記内針が再び貫通されることをブロックするロッキングガイド部とを含み、
前記ロッキングガイド部は、第1のロッキングガイドと第2のロッキングガイドとを含み、
前記第1のロッキングガイドと前記第2のロッキングガイドとは重心が偏心された構造で設けられ、前記内針が前記中空部から引き出されると、重力によって0°超え90°未満の角度で傾きが生じることによって前記中空部の経路が崩れ、
前記第1のロッキングガイドと前記第2のロッキングガイドとは、それぞれ全断面図(Full-section)において、外面の形状が徐々に直径が減少するテーパ状の台形状であり、端部側が互いに対向するように対称配置され、前記内針が前記ロッキングガイド部から引き出されると、前記第1のロッキングガイドと前記第2のロッキングガイドが傾いて、前記第1のロッキングガイドと前記第2のロッキングガイドが行き違いになり、前記第1のロッキングガイドの前記中空部と前記第2のロッキングガイドの前記中空部の中心線がずれることにより前記内針の再刺入が不可能になることを特徴とする、再使用防止安全カテーテル。 - 前記第1のロッキングガイドと前記第2のロッキングガイドは、それぞれ外周に大口径部と小口径部を含むことを特徴とする、請求項1に記載の再使用防止安全カテーテル。
- 前記カニューレプラグから引き出されて前記内針を覆うスライドケースをさらに含み、
前記ロッキングガイド部は、前記スライドケースの前端部に設けられたことを特徴とする、請求項1に記載の再使用防止安全カテーテル。 - 前記スライドケースは、使用者が前記カテーテルハブから前記カニューレプラグを取り外せるように指の引っかかりが生じるホルダーを含み、
前記ロッキングガイド部は、前記ホルダーの内部に設けられたことを特徴とする、請求項3に記載の再使用防止安全カテーテル。 - 前記カニューレプラグを前記カテーテルハブから押し出す弾性力を与えるバネをさらに含み、
前記バネは、前記内針が前記ロッキングガイド部から完全に引き出されるように前記カニューレプラグを前記カテーテルハブから押し出すことを特徴とする、請求項1に記載の再使用防止安全カテーテル。
