Title (EN) CATHETER SYSTEM AND METHOD OF USE
(FR) SYSTÈME DE CATHÉTER ET SON PROCÉDÉ D'UTILISATION
Abstract:
(EN) Urinary tract infections UTI may be over-diagnosed in very young children because of contamination of a urine specimen by external bacteria when using a conventional catheter. The subject matter disclosed herein relates to a coaxial catheter system and methods for its use, comprising an outer catheter that shields the distal collection opening of an inner catheter during insertion of the system through the meatus. Once the system has been deployed, the distal opening of the inner catheter is exposed in order to collect uncontaminated urine. The system may include a variety of mechanisms to advance the inner catheter relative to the outer, or to retract the outer catheter relative to the inner, a halting mechanism to limit distal movement of the outer catheter, a stopping mechanism to limit distal movement of the inner catheter, and a stabilization mechanism to hold the deployed system in place in male patients.
(FR) Les infections des voies urinaires IVU peuvent être sur-diagnostiquées chez de très jeunes enfants en raison de la contamination d'un échantillon d'urine par des bactéries externes lors de l'utilisation d'un cathéter classique. La présente invention concerne un système de cathéter coaxial et des procédés pour son utilisation, comprenant un cathéter externe qui protège l'ouverture distale de collecte d'un cathéter interne pendant l'insertion du système à travers le méat. Une fois que le système a été déployé, l'ouverture distale du cathéter interne est exposée afin de collecter l'urine non contaminée. Le système peut comprendre une variété de mécanismes pour faire avancer le cathéter interne par rapport à l'extérieur, ou pour rétracter le cathéter externe par rapport à l'intérieur, un mécanisme d'immobilisation pour limiter le mouvement distal du cathéter externe, un mécanisme d'arrêt pour limiter le mouvement distal du cathéter interne, et un mécanisme de stabilisation pour maintenir le système déployé en place chez des patients masculins.
