Title
(EN) INTRAVENOUS CATHETER DEVICE HAVING A PROBE ASSEMBLY WITH AN INTEGRATED FLUID FLUSHING MECHANISM
(FR) DISPOSITIF DE CATHÉTER INTRAVEINEUX AYANT UN ENSEMBLE SONDE AVEC UN MÉCANISME INTÉGRÉ DE RINÇAGE DE FLUIDE
Abstract
(EN) An IV catheter device can include or being configured to employ a probe assembly having an integrated fluid flushing mechanism. The probe assembly can be configured in a variety of ways to cause flushing fluid to be injected through a fluid permeable structure of the probe as the probe is advanced distally from a catheter. In this way, the fluid permeable structure can be kept clear of any occlusion that may otherwise form. With the probe extending distally from the catheter, a blood sample may be collected.
(FR) Un dispositif de cathéter IV peut comprendre ou être configuré pour utiliser un ensemble sonde ayant un mécanisme intégré de rinçage de fluide. L'ensemble sonde peut être configuré de diverses manières pour amener un fluide de rinçage à être injecté à travers une structure perméable aux fluides de la sonde lorsque la sonde est avancée de manière distale d'un cathéter. De cette manière, la structure perméable aux fluides peut être maintenue à l'abri de toute occlusion qui pourrait autrement se former. Avec la sonde s'étendant de manière distale du cathéter, un échantillon de sang peut être collecté.
