Abstract

The invention concerns a pump cart for a biological liquid treatment installation, having a first lateral face (40), and a second lateral face (41) by which it is configured to be juxtaposed against a conveying network cart (1) of the installation and a front face (42) meeting the lateral faces (40, 41), and comprising at least one pump (414), a pump support (50) on which is mounted said pump (414), and a guide member for making said pump (414) movable in translation and on which said support (50) is mounted; said support (50) being movable in translation in a direction going from the first lateral face (40) towards the second lateral face (41); whereby said pump (414) is disposed at a predetermined location on said cart (2) depending on the type of treatment carried out.

Claims

1. An installation assembly comprising a pump cart for a biological liquid treatment installation for carrying out different types of treatment, which installation further comprises a conveying network cart, said conveying network cart comprising a network circuit portion between a plurality of connections and having a plurality of circuits;

wherein said pump cart has a first lateral face, a second lateral face by which it is configured to be juxtaposed against said conveying network cart and a front face meeting the two said lateral faces;

said pump cart further comprising;

at least one pump positioned to make liquid flow through said network circuit portion;

a pump support on which is mounted said at least one pump; and

a guide member to render said at least one pump movable in translation and on which said pump support is mounted;

said pump support being movable in translation in a direction going from the first lateral face towards the second lateral face of said pump cart;

whereby said at least one pump is disposed at a predetermined location among a plurality of locations on said pump cart depending on which one of said different types of treatment is carried out.

2. The installation assembly according to claim 1, wherein said guide member comprises two arms spaced apart by slide rods which are furthermore each fastened to each of the two said arms, and the movable pump support comprises a vertical block slidingly mounted on said rods.

3. The installation assembly according to claim 2, wherein said vertical block comprises a system for locking said vertical block against movement in translation on said rods.

4. The installation assembly according to claim 2, wherein said movable pump support comprises a receptacle mounted on a face of said vertical block and configured to receive said at least one pump.

5. The installation assembly according to claim 4, wherein said face of said vertical block is provided with means for hooking said receptacle, and said receptacle is provided with complementary hooking means for its mounting on said face of said block.

6. The installation assembly according to claim 5, wherein said face of said vertical block is equipped with several said hooking means provided at predetermined locations.

7. The installation assembly according to claim 4, wherein said receptacle has a front having a cut-out configured to receive a connecting head of said at least one pump.

8. The installation assembly according to claim 2, wherein said movable pump support and the two said arms are disposed on an upper face of said cart.

9. The installation assembly according to claim 1, further comprising a handle which is movable between a withdrawn position and an extended position in which said movable handle enables said cart to be moved.

10. The installation assembly according to claim 9, wherein said movable handle is removable.

11. The installation assembly according to claim 1, further comprising an internal space situated under an upper face and between the two said lateral faces, said space being configured to receive, at least partially, a biological liquid feed unit.

12. The installation assembly according to claim 11, further comprising a removable panel on said lateral first face which is configured to cover said internal space.

13. The installation assembly according to claim 1, further comprising at least one additional pump which is mounted in superposed configuration on said movable pump support relative to said at least one pump.

14. An installation for treating a biological liquid, comprising:

a pump cart according to claim 1;

a conveying network cart juxtaposed against said second lateral face of said pump cart, which conveying network cart comprises a portion of circuit having a plurality of connectors and a network for conveying liquid between said connectors, said conveying network being formed by a plurality of conduits, and a press comprising a first shell and a second shell mounted on said first shell, said first shell and second shell cooperating to form said conduits of said conveying network; and

a biological liquid feed unit juxtaposed against said first lateral face of said pump cart, which feed unit is configured to feed said at least one pump with biological liquid;

said at least one pump being located facing a connector of a said conduit and being configured to make said biological liquid flow in said conduit.

15. An installation according to claim 14, wherein at least one of said conveying network cart and said feed unit is configured to be nested at least partially within said pump cart.

16. An installation according to claim 14, wherein said feed unit comprises a tank configured to receive a feed container provided to contain said biological liquid, at least one measuring cell for measuring the weight of said tank, said tank resting on said at least one measuring cell when said feed unit is in a working configuration, and at least one weight receiving member for receiving the weight of said tank, said weight receiving member configured such that said tank no longer rests on said at least one measuring cell when said feed unit is in a resting configuration.

17. An installation according to claim 16, wherein said at least one measuring cell is interposed between two plates, one of which is fastened to said tank and the other to said feed unit, and said weight receiving member is formed by a cam interposed between the two said plates and by a crank configured to move said cam so as to move the two said plates apart.

18. An installation according to claim 16, wherein said feed unit comprises the same number of weight receiving members as there are measuring cells.

19. An installation according to claim 14, wherein said feed unit has a first lateral face provided with a plurality of valves and a second lateral face which is an opposite face to said first lateral face and which faces said pump cart.

20. An installation according to claim 14, wherein said conveying network cart comprises a base having a front face, a movable or removable door, said first shell being disposed on said front face of said base and said second shell being disposed in said door, said conveying network cart having a closed door position in which said conduits are formed, said second shell furthermore being of transparent material and said door being at least partly of transparent material.

21. An installation for treating a biological liquid, comprising:

a pump cart according to claim 1;

a conveying network cart juxtaposed against said second lateral face of said pump cart, which conveying network cart comprises a portion of circuit having a plurality of connectors and a network for conveying liquid between said connectors, said conveying network being formed by a plurality of conduits, and a press comprising a first shell and a second shell mounted on said first shell, said first shell and second shell cooperating to form said conduits of said conveying network; and
