A method and system for treating, by filtration, haemorrhagic fluid contained in a container with a view to subsequent autotransfusion, including at least one step of concentrating by filtration said haemorrhagic fluid in order to increase the concentration of red blood cells in the haemorrhagic fluid to reach a target haematocrit level while at the same time removing from the haemorrhagic fluid a filtrate comprising compounds not desired for autotransfusion, further including:

System and method for treating haemorrhagic fluid for autotransfusion

The invention relates to a system, and the associated method for using said system, for treating haemorrhagic fluid previously taken from a patient for the purpose of autotransfusion, comprising a unit for treating () haemorrhagic fluid, said treatment unit () comprising:

A device for the filtration of a complex fluid composition such as blood, includes a base () with a bottom (), a top () with a bottom (), and a membrane () that is arranged between the base and the top so as to define a low chamber Cand a high chamber C, with an input tap () of the complex composition that is to be filtered emptying into the low chamber C, an output tap () of the retentate with elements for adjusting the flow rate emptying into this same low chamber C, and an output tap (-) of the high chamber C, whereby this output tap (-) of the permeate is subjected to negative pressure.

Device for the filtering a complex liquid such as blood, in particularly applicable to an autotransfuser

A process for treating the hemorrhage fluids of a patient at the time of a surgical procedure with the aim of carrying out an autotransfusion, includes a stage for recovering the hemorrhage fluids with simultaneous introduction of agents such as anticoagulant and/or diluting agents, at least one stage for the mechanical separation/concentration of this hemodiluted hemorrhage fluid in order to concentrate its content in red blood cells and partially purify it, this phase being collected in a sterile manner so as to be fit for injecting back to the patient. Also described is the related device.
