A self-contained sterile catheter apparatus (10) for use with an intravenous cannula element (24). The cannula element has first and second ends and a bore formed therebetween, and is configured for transcutaneous positioning such that the first end is adapted to protrude from a limb of a subject and the second end is brought into communication with an interior of a body organ of a subject. The self-contained sterile catheter apparatus includes first and second ends and a flexible catheter tube therebetween, the catheter tube (40) having a predetermined length and a diameter adapted for slidable insertion through the bore of the intravenous cannula element into the subject, and an integral sterile environment containment element (48) thereby to allow insertion of the catheter tube through the cannula element into the subject in a generally non-sterile environment.

L'invention concerne un appareil cathéter stérile autonome destiné à être utilisé avec un élément de canule intraveineuse. L'élément de canule comporte un alésage entre ses première et seconde extrémités, et il est conçu pour un positionnement transcutané de façon que la première extrémité dépasse d'un membre d'un sujet et que la seconde extrémité soit amenée en communication avec l'intérieur d'un organe corporel d'un sujet. L'appareil cathéter stérile autonome comprend un tube de cathéter flexible entre ses première et seconde extrémités, le tube de cathéter étant de longueur déterminée et de diamètre adapté à une insertion glissante par l'alésage de l'élément de canule intraveineuse dans le sujet, ainsi qu'un élément intégral de confinement en environnement stérile permettant ainsi l'insertion du tube de cathéter par l'élément de canule dans le sujet dans un environnement généralement non stérile.
