CA 2626302

A chamber is described for use in an extracorporeal fluid system. The chamber has a bottom entry port and a bottom exit port. A microporous filter at the top of the chamber allows air in the fluid to vent from the chamber. In use, the chamber is filled with saline. Blood is then introduced into the chamber. A layer of saline is above a layer of blood in the chamber. The saline stagnates as the blood flows through the chamber. The saline keeps the blood from contacting the filter and depositing protein on the filter.

L'invention concerne une chambre destinée à être utilisée dans un système fluidique extracorporel. La chambre présente un orifice d'entrée inférieur et un orifice de sortie inférieur. Un filtre microporeux situé au-dessus de la chambre permet à l'air du fluide d'être évacué de la chambre. Lors de l'utilisation, la chambre est remplie d'une solution saline. Du sang est ensuite introduit dans la chambre. Une couche de solution saline est située au-dessus d'une couche de sang dans la chambre. La solution saline stagne tandis que le sang circule dans la chambre. La solution saline empêche le sang d'entrer en contact avec le filtre et de déposer des protéines sur le filtre.
