- 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、
前記内針が貫通する中空が形成され、貫通した前記内針の引き出しの際に前記中空が歪められて前記内針が再び貫通することをブロックするロッキングガイド部と、を含むことを特徴とする、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2に記載の再使用防止安全カテーテル。 - 前記カテーテルハブの内部に設けられて血液の逆流を遮断する血液遮断部をさらに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。
- 前記ロッキングガイド部は、
前記カニューレプラグと独立した射出品であり、前記カニューレプラグ内において前記内針により固定された状態を保つが、前記内針が引き出されて固定力が除去されれば、傾きが生じて前記中空の位置が変更されることを特徴とする、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が当接することにより前記内針が貫通する前記中空の経路が長手方向に形成され、
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は、前記内針により変位が固定されることを特徴とする、請求項1に記載の再使用防止安全カテーテル。 - 前記ロッキングガイド部は、
0°超90°未満の角度で重力により傾きが生じる構造的な形状に配設され、
前記内針が引き出されると、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の固定力が除去されて前記第1のロッキングガイドと前記第2のロッキングガイドのそれぞれに傾きが生じ、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の行き違いにより長手方向の中空の経路が崩れることを特徴とする、請求項6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。
