Device for a biological liquid treatment installation
The invention concerns a device comprising a base ( 2 ) and a door ( 20 ), said device having a closed door position in which a circuit ( 8 ) of the device comprises a bag comprising two flexible films and connectors of the conveying network, and a press ( 9 ) comprising a first shell ( 16 ) disposed on a front face ( 5 ) of said base ( 2 ) and a second shell ( 17 ) disposed in said door ( 20 ); and a hinge system hinging said door ( 20 ) relative to said base ( 2 ), and disposed only on one side of said door ( 20 ) so as to form lateral clearances between said door ( 20 ) and said base ( 2 ) over the rest of a perimeter of said door ( 20 ).
1. A device for a biological liquid treatment installation, comprising:
a base having a front face;
a movable door movable between an open and a closed position, said movable door having a perimeter;
a circuit comprising a plurality of connectors and a network having conduits for conveying liquid between said connectors, which circuit comprises a bag comprising two flexible films and said connectors, which circuit further comprises a press comprising a first shell disposed upright on said front face of said base and a second shell mountable 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, the conduits of said network;
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 clearance between the door and the base over the rest of the perimeter of the door, so as to enable free access to the connectors.
2. The device of claim 1 , 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 connectors emerging on the inside and on the outside of at least one side of said outline.
3. The device of claim 1 , wherein said bag further comprises first through apertures on one side of said bag for its positioning, and said first shell comprising studs for hooking said bag to an upper part of said first shell, said hooking studs passing through said first through apertures of said bag.
4. The device of claim 1 , wherein said hinge system comprises a single hinge disposed at a corner of said door, and said single 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.
5. The device of claim 1 , wherein said hinge system has a pivot axis about which said movable door pivots between said open and closed position, and wherein said pivot axis is offset from a joining plane formed between said first shell and second shell in the closed door position.
6. The device according to claim 1 , further comprising a locking system configured such that it locks together said first shell and said second shell.
7. The device according to claim 6 , wherein said 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 a second through aperture and emerging into a first hole of said second shell, said balls entering said head in said unlocked state of said ball-lock pin and projecting from said head in said locked state of said ball-lock pin.
8. The device according to claim 1 , wherein when said door is in said closed door position, said second shell is disposed in said door, and when said door is not in said closed door position, said bag is carried only by the first shell.
