A catheter apparatus (10) for intravenous applications, such as hemodialysis, which helps prevent needlesticks. The invention includes a hollow plunger (20) to which a hollow needle (14) is attached. A housing (12) surrounds the plunger (20) and contains a locking device (22) so that when the plunger (20) is retracted and the needle (14) is pulled within the housing (12), the plunger (20) becomes locked into place, thus encasing and securing the needle. A standard IV tubing line is attached to the apparatus, the introducing needle (14) inserted so that the catheter is placed in position, and then the introducing needle (14) is withdrawn and locked in place without the need for the operator having to break the system. Once the needle (14) is locked into position, medical personnel are protected from a needlestick as the entire needle is within the apparatus.
Cathéter (10) à usage intraveineux (notamment pour des hémodialyses) évitant les piqûres d'aiguilles. Il comporte un piston creux (20) auquel est fixée une aiguille creuse (14). Un manchon (12) entourant le piston (20) contient un dispositif de verrouillage tel que, lorsque le piston (20) est rétracté et l'aiguille (14) ramenée dans le manchon (12), le piston (20) se bloque en enserrant et immobilisant l'aiguille. Un conduit normalisé de type IV est relié à l'appareil et l'aiguille (14) introduite pour mettre le cathéter en place, puis l'aiguille (14) est retirée et immobilisée sans que le praticien ait à rompre le système. Une fois l'aiguille bloquée, le personnel médical est protégé des piqûres, d'aiguille puisque la totalité de l'aiguille se trouve à l'intérieur de l'appareil.
