A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit "flashback" of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.

La présente invention concerne un ensemble cathéter pouvant être chassé, qui possède des caractéristiques permettant une activation sélective du flux de fluide à travers l'ensemble cathéter. Un septum est placé dans l'adaptateur de cathéter de l'ensemble cathéter, et comprend un passage qui est fermé avant d'être ouvert en biais via un activateur de septum également positionné dans l'adaptateur de cathéter. Une pluralité de canaux de prise d'air est intercalée entre le septum et la surface interne de l'adaptateur de cathéter, pour permettre le « retour en arrière » du sang durant l'insertion du cathéter dans un patient. On fait avancer l'activateur de septum à travers le passage du septum tandis qu'un coupleur est fixé à une ouverture proximale de l'adaptateur du cathéter.
