The invention relates to a bag system (1) for sampling a biological fluid, in particular a blood fluid, said system being intended to be used in a sampling machine comprising a peristaltic pump (24), said system comprising, in closed circuit , means for withdrawing (2) the fluid, a pocket (3) containing an anticoagulant solution and / or for storing the withdrawn fluid, and a collection pocket (4) intended to receive the withdrawn fluid added with the anticoagulant solution and / or conservation. The collection bag (4) is in fluid communication with the withdrawal means (2) via a first flexible tube (5) provided with a connector (6) and with the bag (3) containing the solution anticoagulant and / or preservation via a second flexible tube (7) connected to said connector (6). An association device (18, 20) is provided between the first (5) and second (7) pipes, said association device being arranged to allow, between the connector (6) and the association means (18, 20), the formation of a loop with the second tube (7), the conformation of said loop being arranged to allow its arrangement around at least part of a head of the peristaltic pump (24). |
