Abstract

The invention concerns a device comprising:

• • a base (2);
  • a moveable or removable door (20), said device having a closed door position; and
  • in the closed door position, a circuit (8) comprising a bag comprising two flexible films and conveying network connectors, and a press (9) comprising a first shell (16) disposed on said front face (5) of said base (2) and a second shell (17) disposed in said door (20);
  • said bag being clamped between said first shell (16) and said second shell (17) in a state in which conduits of said network for conveying liquid are formed between said films.

Claims

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

a base (2) having a front face (5);

a moveable or removable door (20), said device having a closed door position; and

in the closed door position, a circuit (8) comprising a plurality of connectors (11) and a network (12) for conveying liquid between said connectors (11), which circuit (8) comprises a bag (10) comprising two flexible films (65, 66) and said conveying network connectors (11), which circuit (8) further comprises a press (9) comprising a first shell (16) disposed on said front face (5) of said base (2) and a second shell (17) disposed in said door (20);

said bag (10) being clamped between said first shell (16) and said second shell (17) in a state in which conduits (13) of said network (12) for conveying liquid are formed between said films (65, 66).

2. A device according to claim 1, wherein it has a position other than said closed door position in which said bag (10) is carried only by the first shell (16).

3. A device according to claim 1, wherein the two said flexible films (65, 66) of said bag (10) are joined to each other and delimit a zone (67) for treatment of said liquid according to a closed outline, said conveying network connectors (11) emerging on the inside and on the outside of at least one side (68, 69, 70) of said outline.

4. A device according to claim 1, wherein said base (2) of said device (1) comprises, on its front face (5), a console-forming inclined chassis (25) on which is disposed the first shell (16), which chassis (25) comprises hooking claws (26), and the first shell (16) comprises dowels (100) engaged in said hooking claws (26).

5. A device according to claim 1, wherein said bag (10) comprises first through apertures (73) on a side (71) of said bag (10) for its positioning, and said first shell (16) comprises studs (106) for hooking said bag (10) which pass through said first through apertures (73) of said bag (10).

6. A device according to claim 1, further comprising a hinge system hinging said door (20) relative to said base (2), said hinge system being disposed only on one side of said door (20) so as to form, in said closed door position, lateral clearances between said door (20) and said base (2) over the rest of a perimeter of said door (20), so as to enable free access to connectors (11) of said bag (20).

7. A device according to claim 6, wherein said hinge system comprises a single hinge (42) disposed at a corner of said door (20), and said hinge (42) comprises a first hinge portion (43) fastened to said corner of said door (20) and a second hinge portion (44) fastened to a lateral face (3) of said device (2), which lateral face (3) is connected to said front face (5).

8. A device according to claim 7, wherein the axis of said hinge (42) is offset from a joining plane (P) formed between said first shell (16) and said second shell (17) in the closed door position.

9. A device according to claim 1, further comprising a first locking system (55) for fastening said second shell (17) into a frame (35) of said door (20), which first locking system (55) comprises:

at least one jack (56) disposed in said frame (35);

at least one spring (59) disposed in said frame (35);

at least one rod (57) linked to said at least one jack (56) by a first end and to at least one spring (59) by a second end that is an opposite end to the first end, said at least one rod (57) comprising at least one locking bolt (58) and having an unlocked position and a locked position; and

at least one lock strike (89) arranged in a recess of said second shell (17);

said at least one jack (56) being configured to actuate the passage of said at least one rod (57) between its locked position and its unlocked position;

said at least one spring (59) being configured to actuate the passage of said at least one rod (57) between its unlocked position and its locked position; and

said at least one locking bolt (58) being engaged in said at least one lock strike (89) in the locked position of said rod (57) and being disengaged from said at least one lock strike (89) in the unlocked position of said rod (57).

10. A device according to claim 1, further comprising a second locking system configured such that it locks together said first shell (16) and said second shell (17) in the closed door position.

11. A device according to claim 10, wherein said second shell (17) has a first hole (88), said bag (10) comprises at least one second through aperture (75) in a treatment zone (67) of said liquid, and said second locking system comprises at least one ball-lock pin (110) provided with a body (111), a head (114) and balls (119) and having an unlocked state and a locked state, said ball-lock pin (110) being fastened to said first shell (16), said head (114) passing through said first shell (16) and said second through aperture (75) and emerging into said first hole (88) of said second shell (17) in the closed door position, said balls (119) entering said head (114) in said unlocked state of said pin (110) and projecting from said head (114) in said locked state of said pin (110).
