Device for a biological liquid treatment installation

1. A device for a biological liquid treatment installation, comprising:

a base having a front face;

a moveable or removable door, said device having a closed door position;

in the closed door position, 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 on said front face of said base and a second shell disposed in said door; and

a hinge system hinging said door relative to said base, said hinge system being disposed only on one side of said door so as to form, in the closed door position, lateral clearances between said door and said base over the rest of a perimeter of said door, so as to enable free access to the connectors of said bag.

2. A device according to claim 1 , wherein said hinge system comprises a single hinge disposed at a corner of said door, and said hinge comprises a first hinge portion fastened to said corner of said door and a second hinge portion fastened to a lateral face of said device, which lateral face is connected to said front face.

3. A device according to claim 2 , wherein said axis of said hinge is offset from a joining plane formed between said first shell and second shell in the closed door position.

4. A device according to claim 1 , wherein said base of said device comprises, on its front face, a console-forming inclined chassis on which is disposed the first shell, which chassis comprises hooking claws, and the first shell comprises dowels engaged in said hooking claws.

5. A device according to claim 1 , further comprising a first locking system for fastening said second shell into a frame of said door, which first locking system comprises:

at least one jack disposed in said frame;

at least one spring disposed in said frame;

at least one rod linked to said at least one jack by a first end and to at least one spring by a second end that is an opposite end to the first end, said at least one rod comprising at least one locking bolt and having an unlocked position and a locked position; and

at least one lock strike arranged in a recess of said second shell;

said at least one jack being configured to actuate the passage of said at least one rod between its locked position and its unlocked position;

said at least one spring being configured to actuate the passage of said at least one rod between its unlocked position and its locked position; and

said at least one locking bolt being engaged in said at least one lock strike in the locked position of said rod and being disengaged from said at least one lock strike in the unlocked position of said rod.

6. A device according to claim 1 , further comprising a second locking system configured such that it locks together said first shell and said second shell when said door is in the closed door position.

7. A device according to claim 6 , wherein said second shell has a first hole, said bag comprises at least one first through aperture in a treatment zone of said liquid, and said second locking system comprises at least one ball-lock pin provided with a body, a head and balls and having an unlocked state and a locked state, said ball-lock pin being fastened to said first shell, said head passing through said first shell and said first through aperture and emerging into said first hole of said second shell in the closed door position, said balls entering said head in said unlocked state of said pin and projecting from said head in said locked state of said pin.

8. A device according to claim 1 , wherein said circuit comprises instruments necessary for the treatment of said biological liquid, comprising valves to allow or prevent the passage of said liquid in said conduits, and/or sensors of physico-chemical values of said liquid, and said instruments are integrated into said first shell.

9. A device according to claim 8 , wherein said first shell comprises a first connector at the back, and said base of said device comprises a second connector configured such that it connects to said first connector to power said instruments integrated into said first shell.

10. A device according to claim 9 , wherein said front face of said base comprises a frame provided with an opening, and said second connector is configured such that it passes through said opening to connect to said first connector.

11. A device according to claim 1 , wherein, in the closed door position, said bag is clamped between the first and second shells in a state in which conduits of said network for conveying liquid are formed between said films.

12. A device according to claim 11 , wherein the two said flexible films of said bag are joined to each other and delimit a zone for treatment of 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.

13. A device according to claim 12 , wherein said bag comprises side through apertures on a side of said bag for its positioning, and said first shell comprises studs for hooking said bag which pass through said side through apertures of said bag.

14. A device according to claim 11 , wherein said bag comprises at least one side through aperture on a side of said bag, said first shell comprises at least one dowel, and said second shell comprises at least one second hole, wherein, in the closed door position, said at least one dowel passes through said side through aperture of said bag and said at least one second hole receives said dowel of said first shell.

15. A device according to claim 1 , wherein it has a position other than said closed door position in which said bag is carried only by the first shell.

16. A device according to claim 15 , wherein the two said flexible films of said bag are joined to each other and delimit a zone for treatment of 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.

17. A device according to claim 16 , wherein said bag comprises side through apertures on a side of said bag for its positioning, and said first shell comprises studs for hooking said bag which pass through said side through apertures of said bag.
