摘要：
The invention relates to a treatment system, and method for using it, of a haemorrhagic fluid previously removed from a patient for autotransfusion, including a treatment unit (100) for haemorrhagic fluid, said treatment unit. (100) comprising: - a filtration device (110) for tangential filtration comprising a filtration membrane (113) arranged in a housing (114) so as to separate an inlet chamber (111) from an evacuation chamber (112), the inlet chamber (111) and the evacuation chamber (112) each having an inlet (111a； 112a) and an outlet (111b； 112b) for fluids； a treatment bag (140) having an inlet (140a) and an outlet (140b) fluidly connected by a recirculation line (150) to the outlet (111b) and the inlet (111a) of the admission chamber (111) of the filtering device (110), respectively, allowing circulation of the hemorrhagic fluid in the recirculation line (150) in a direction from the outlet (140b) of the treatment bag (140) to 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 evacuation chamber (112) of the filtration device (110) for supplying a cleaning liquid into said evacuation chamber (112)； and - a first flow control member (181) arranged for flow control in the cleaning line (180) and a second flow control member (131) arranged for flow control in an evacuation line ( 130) fluidly connected to the outlet (112b) of the discharge chamber (112) of the filtration device (110) so as to control the cleaning liquid pressure in the evacuation chamber (112). 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
