Claims (11)
- 生物学的部位へのアクセスを提供する安全カテーテル・システムであって、
内腔を画定し、生物学的部位に挿入するための第1端、および第2端を有するカテーテルと、
カテーテルの内腔を通る流体の流れを制御するコネクタとを有し、コネクタは、流体がコネクタを通って流れることができる内部流体通路を有し、コネクタが、
第1口および第2口を有するハウジングを有し、第1口は、鈍カニューレを受けるような構成であり、第2口は、カテーテルの第2端に接続され、さらに、
ハウジング内に位置決めされた可動要素を有し、可動要素は、可動要素がハウジングを通る流体の流れを遮断するハウジングの第1位置と、可動要素がハウジングを通る流体の流れを許容するハウジング内の異なる位置の第2位置とを有する安全カテーテル・システムに於いて、
可動要素が、コネクタを通る流体通路の一部を形成する自然に開放するボアを画定する頭部を有し、頭部は、可動要素が第2位置にある場合、ボアが自然に開放し、それによってコネクタを通る流体の流れを許容するように構成され、頭部はさらに、可動要素が第1位置に戻ると、ボアが閉構成をとり流体の流れを防止するように構成され、
さらに挿入機構を有し、挿入機構が、
ハウジングの第1口を通って挿入され、可動要素の頭部と接触して、可動要素をボアが開放する第2位置へと移動させるように構成された鈍カニューレを有し、鈍カニューレは、第2位置に移動された可動要素の頭部の自然に開放したボア内で滑動するようにも構成され、さらに、
鋭先端を有する針を有し、針は、鈍カニューレと滑動自在に係合し、且つ鈍カニューレが第2位置に移動された可動要素の自然に開放したボア内で滑動した後に鈍カニューレを貫通できる長さを有し、針は、鋭先端が生物学的部位を貫通して、カテーテルを生物学的部位内に配置するように、鋭先端がカテーテルの第1端を越えて突出するまで、カテーテルを通って滑動するようにも構成される、安全カテーテル・システム。 - ハウジングが、可動要素の第2位置にて拡大した内径を有し、
頭部は、可動要素がハウジングの拡大した内径の第2位置にある場合に、ボアが自然に開放する構成をとることができ、それによってコネクタを通る流体の流れを許容するように構成される、請求項1に記載の安全カテーテル・システム。 - 挿入機構がさらに、鋭針に結合した制御ハンドルを有し、したがって制御ハンドルが動作すると鋭針が動作し、
制御ハンドルが動作すると、鈍カニューレも挿入機構から所定の長さだけ延在して、コネクタに入る、請求項1に記載の安全カテーテル・システム。 - システムがさらに、鈍カニューレが可動要素をボアが開放する第2位置まで移動させるように十分に延在している位置で鈍カニューレをロックするような構成であるロック器具を有し、したがって挿入機構からさらに延在せず、挿入機構内に後退もしない、請求項3に記載の安全カテーテル・システム。
- 挿入機構がさらに、
挿入機構の使用者を鋭先端による穿刺から保護するために、針の鋭先端に物理的バリアを提供するように配置された鋭針の保護器具を有し、
制御ハンドルが、保護器具を鋭針と係合させて、バリアを提供するようにも構成される、請求項3に記載の安全カテーテル・システム。 - 挿入機構がさらに、制御ハンドルが針保護位置に移動したら、制御ハンドルをその位置に永続的に保護するように構成された制御ハンドル・ロック器具を有する、請求項5に記載の安全カテーテル・システム。
- ハウジングが、第1口に隣接して配置されたねじ山を有し、挿入機構も、ハウジングと挿入機構をねじ係合できるようにねじ山を有する、請求項1に記載の安全カテーテル・システム。
- さらに、針を囲む針チューブを有し、針が鋭先端を有し、挿入機構が制御ハンドルを有し、針チューブは、制御ハンドルが後退位置にある場合に、針の鋭先端が針チューブに覆われて、挿入器具の使用者を鋭先端による穿刺から保護するように構成され、制御ハンドルが延在位置にある場合に、針の鋭先端が針チューブの外側にあり、したがって針がカテーテル内に延在できるように構成される、請求項1に記載の安全カテーテル・システム。
- 更に、鈍カニューレに接続された制御チューブを有し、制御チューブが、鈍カニューレの第1端に向かう移動を制限する制限器具を有する、請求項8に記載の安全カテーテル・システム。
- さらに、針の鋭先端が針チューブにより覆われるように鋭針を針チューブ内の後退位置に保持するロック機構を有する、請求項9に記載の安全カテーテル・システム。
- ハウジングの第1口が、流体連絡のために標準的なオス・ルアー・コネクタ先端を受けるメス・ルアー・アダプタを有する、請求項1に記載の安全カテーテル・システム。
