Device for a biological liquid treatment installation

摘要

The invention concerns a device comprising a circuit comprising a bag (10) comprising two flexible films (65, 66), a press (9) comprising a first shell (16) disposed upright on a front face of a base of the device and a second shell (17) mounted on said first shell, which shells clamp said bag to form conduits (13); said press is provided with a system (170) for jamming at the location of a treatment zone (67) of the bag, which comprises a jamming member (171) provided with at least one jamming nipple (173) and a complementary jamming member (172) provided with a jamming channel (174) configured to receive said nipple; said jamming member (171) and complementary jamming member (172) and said bag (10) being configured in order for the latter to have a portion (175) in said treatment zone in which said films are jammed between said nipple and said channel.

1. A device for a biological liquid treatment installation, comprising a base having a front face, and a circuit comprising a plurality of connectors and a network for conveying liquid between said connectors, which circuit comprises a bag comprising two flexible films and said conveying network connectors, which circuit further comprises a press comprising a first shell disposed upright on said front face of said base and a second shell mounted on said first shell, said first shell and second shell cooperating with said bag to form, between said flexible films, by clamping of said bag between said first shell and said second shell, conduits of said conveying network; the two said flexible films of said bag being joined to each other and delimiting a treatment zone for said liquid according to a closed outline, said conveying network connectors emerging on the inside and on the outside of at least one side of said outline;
wherein said press is provided with a system for jamming said bag at the location of said treatment zone thereof, said jamming system comprising at least one jamming member for jamming said bag and at least one complementary jamming member for jamming said bag, said at least one jamming member being provided with at least one jamming nipple and said at least one complementary jamming member being provided with at least one jamming channel configured to receive said at least one jamming nipple; said at least one jamming member, said at least one complementary jamming member and said bag being configured in order for the latter to have at least one portion in said treatment zone in which said films are jammed between said at least one jamming nipple and said at least one jamming channel.
