Title
(EN) DEVICE FOR PREVENTING A FREE CATHETER FLOW
(FR) DISPOSITIF POUR EMPÊCHER L'ÉCOULEMENT LIBRE D'UN CATHÉTER
Abstract
(EN)
The invention relates to a catheter, comprising a catheter wall and a flow region limited by the catheter wall, for connecting an administering device to an administering needle, characterised by at least one catheter portion at which at least one partial piece of an inner wall of the catheter abuts at least one other partial piece of an inner wall of the catheter, in order to block or obstruct the flow of a medium through the catheter, wherein the flow is opened when the medium exhibits a pressure above a predetermined blocking pressure.
(FR)
L'invention se rapporte à un cathéter comprenant une paroi de cathéter et une région d'écoulement limitée par la paroi du cathéter afin de raccorder un dispositif d'administration à une aiguille d'administration, caractérisé par au moins une partie de cathéter au niveau de laquelle au moins un morceau partiel de paroi interne du cathéter vient buter contre au moins un autre morceau partiel de paroi interne du cathéter afin de bloquer ou d'obstruer l'écoulement d'un milieu à travers le cathéter, l'écoulement étant ouvert lorsque le milieu présente une pression supérieure à une pression de blocage prédéterminée.
