Bag for a circuit of a biological liquid treatment installation

摘要

The invention concerns a bag comprising a first conduit (13J), a second conduit (13K), the first section (13J1) of the first conduit (13J) and the first section (13K1) of the second conduit (13K) being opposite; a third conduit (13L) linking said first respective ends (13J2, 13K2) of said first respective sections (13J1, 13K1); a fourth conduit (13M) linking said second respective ends (13J3, 13K3) of said first respective sections (13J1, 13K1); a fifth conduit (13N) linking both said second end (13J3) of said first section (13J1) and said first end (13M1) of said fourth conduit (13M), and said fifth conduit (13N) linking both said first end (13K2) and said second end (13L2) of said third conduit (13L); said first conduit (13J) and said second conduit (13K) each being connected to a chromatography column connector (11M).

1. A bag for a circuit of an installation for treatment of a biological liquid by chromatography, comprising:
a plurality of connectors (11A-11R) and a network (12) for conveying liquid between said connectors (11A-11R), said conveying network (12) being formed by a plurality of conduits (13A-13Q); and two flexible films (65, 66) fastened to each other, said conduits (13A-13Q) being formed between the two said flexible films (65, 66); wherein a first conduit (13J) is provided with a first section (13J1), which has a first end (13J2) and a second end (13J3) which is an opposite end to the first end (13J1); wherein a second conduit (13K) is provided with a first section (13K1), which has a first end (13K2) and a second end (13K3) which is an opposite end to the first end (13K2), the first section (13J1) of the first conduit (13J) and the first section (13K1) of the second conduit (13K) being opposite; wherein a third conduit (13L) has a first end (13L1) and a second end (13L2) which is an opposite end to the first end (13L1), which third conduit (13L) links said respective first ends (13J2, 13K2) of said respective first sections (13J1, 13K1) of said first conduit (13J) and said second conduit (13K) respectively by its first end (13L1) and its second end (13L2); wherein a fourth conduit (13M) has a first end (13M1) and a second end (13M2) which is an opposite end to the first end (13M1), which fourth conduit (13M) links said respective second ends (13J3, 13K3) of said respective first sections (13J1, 13K1) of said first conduit (13J) and said second conduit (13K) respectively by its first end (13M1) and its second end (13M2); wherein a fifth conduit (13N) has a first end (13N1) and a second end (13N2) which is an opposite end to the first end (13N1), said fifth conduit (13N) linking both the second end (13J3) of said first section (13J1) of said first conduit (13J) and said first end (13M1) of said fourth conduit (13M) by its first end (13N1), and said fifth conduit (13N) linking both said first end (13K2) of said first section (13K1) of said second conduit (13K) and said second end (13L2) of said third conduit (13L) by its second end (13N2); and said first conduit (13J) being connected to a chromatography column connector (11L) by said first end (13J2) of its first section (13J1), and said second conduit (13K) being connected to a chromatography column connector (11M) by said second end (13K3) of its first section (13K1); whereby the bag is configured such that the liquid to treat passes into said chromatography column via one of said first (13J) and second (13K), conduits, exits via the other of said first (13J) and second (13K) conduits, and the liquid to treat may avoid said chromatography column by passing into said fifth conduit (13N).
