Title
(EN) APPARATUS FOR BIOPROCESSING A CIRCULATING FLUID
(FR) SYSTEME DE TRAITEMENT BIOLOGIQUE D'UN LIQUIDE CIRCULANT
Abstract
(EN)
The invention relates to the safe and effective bio-treatment of circulating fluids. In one general aspect of the invention, an apparatus (5) (e.g., liver assist system) for circulating and bioprocessing a fluid (e.g., plasma) includes a conduit (6) for circulating the fluid, an oxygenator (22) for supplying oxygen to the fluid, a pump (14) adapted to circulate the fluid through the conduit (6), a bioreactor unit (8), connected within the conduit (6), adapted to process the fluid, and a container (28) connected within the conduit for receiving and releasing a portion of the fluid.
(FR)
Cette invention a pour objet un système biologique sûr et efficace de traitement des liquides circulants. Selon un aspect général de l'invention, un appareil (5) (système d'assistance hépatique par exemple), destiné à la mise en circulation et au traitement biologique du liquide (plasma par exemple), comprend un conduit (6) pour faire circuler le liquide, un oxygénateur (22) pour oxygéner le liquide, une pompe (14) permettant de faire circuler le liquide à travers le conduit (6), une unité de bioréaction (8) reliée par le conduit (6) permettant de traiter le liquide, ainsi qu'un récipient (28) relié par le conduit permettant de recevoir et de libérer une partie du liquide.
