Abstract

L'invention porte sur un système de traitement, et son procédé d'utilisation associé, d'un liquide hémorragique préalablement prélevé un patient en vue d'une autotransfusion, incluant une unité de traitement (100) du liquide hémorragique, ladite unité de traitement (100) comprenant : - un dispositif de filtration (110) pour filtration tangentielle comprenant une membrane de filtration (113) agencée dans un boitier (114) de manière à séparer une chambre d'admission (111) d'une chambre d'évacuation (112), la chambre d'admission (111) et la chambre d'évacuation (112) ayant chacune une entrée (111a ; 112a) et une sortie (111b ; 112b) de fluides ; - une poche de traitement (140) ayant une entrée (140a) et une sortie (140b) reliées fluidiquement par une ligne de recirculation (150) à la sortie (111b) et à l'entrée (111a) de la chambre d'admission (111) du dispositif de filtration (110), respectivement, permettant une circulation du liquide hémorragique dans la ligne de recirculation (150) dans un sens allant de la sortie (140b) de la poche de traitement (140) vers l'entrée (140a) de la poche de traitement (140) à travers la chambre d'admission (111) du dispositif de filtration (110) ; une ligne de nettoyage (180) reliée fluidiquement à l'entrée (112a) de la chambre d'évacuation (112) du dispositif de filtration (110) pour amener un liquide de nettoyage dans ladite chambre d'évacuation (112) ; et - un premier organe de régulation de flux (181) agencé pour une régulation de flux dans la ligne de nettoyage (180) et un deuxième organe de régulation de flux (131) agencé pour une régulation de flux dans une ligne d'évacuation (130) reliée fluidiquement à la sortie (112b) de la chambre d'évacuation (112) du dispositif de filtration (110), de manière à pouvoir contrôler la pression de liquide de nettoyage dans la chambre d'évacuation (112).The invention relates to a system for processing, and its associated method of use, of a haemorrhagic liquid previously withdrawn from a patient with a view to autotransfusion, including a processing unit (100) for the haemorrhagic fluid, said processing unit (100) comprising: - a filtration device (110) for tangential filtration comprising a filtration membrane (113) arranged in a box (114) so as to separate an inlet chamber (111) from an outlet chamber (112), the inlet chamber (111) and the outlet chamber (112) each having an inlet (111a; 112a) and an outlet (111b; 112b) for fluids; - a treatment pocket (140) having an inlet (140a) and an outlet (140b) fluidically connected by a recirculation line (150) to the outlet (111b) and to the inlet (111a) of the admission chamber (111) of the filtration device (110), respectively, allowing circulation of the haemorrhagic liquid in the recirculation line (150) in a direction going from the outlet (140b) of the treatment bag (140) towards the inlet ( 140a) of the treatment bag (140) through the inlet chamber (111) of the filtration device (110); a cleaning line (180) fluidly connected to the inlet (112a) of the exhaust chamber (112) of the filtration device (110) for feeding a cleaning liquid into said exhaust chamber (112); and - a first flow regulating member (181) arranged for flow regulation in the cleaning line (180) and a second flow regulating member (131) arranged for flow regulation in an evacuation line ( 130) fluidically connected to the outlet (112b) of the evacuation chamber (112) of the filtration device (110), so as to be able to control the cleaning liquid pressure in the evacuation chamber (112).
