Abstract

(57)【要約】 第１：負圧を生じ、中心静脈への穿剌の際に血液を吸引し、穿剌を自動的に確認する、ベロ−付きバル−ンを有する。第２：血液の流出を避けて、カテ−テルの迅速な初期の導入を可能にする自動引き金を有する。若干の血液が流出する場合、血液はプラスチックバル−ン内に留められるので、使用者は汚染されない。第３：迅速取付フックは安全で、しかも従来品を使用する場合に通常行われる患者への縫合糸による縫付けを不要とする。 (57) [Summary] No. 1: It has a bellowed balloon that generates negative pressure, draws blood when puncturing the central vein, and automatically confirms puncturing. Second: having an automatic trigger that allows for a rapid initial introduction of the catheter, avoiding blood spills. If some blood escapes, the user will not be contaminated since the blood will remain in the plastic balloon. Third: the quick attach hook is safe and eliminates the need for suture suturing to the patient, which is usually done when using conventional products.
