Normothermic perfusion device suitable for maintaining a liver or a kidney in optimal physiological conditions

A normothermic perfusion device (1) to maintain in optimal physiological conditions a liver or kidney intended to be transplanted, wherein said device (1) comprises a permanent part (2) and a disposable part (3), wherein:

• the permanent part (2) comprises:
• pumps, heating elements and a control system, configured to regulate fluids in a hydraulic circuit (17) and the temperature of said fluids, whether the container (4) houses a liver or a kidney, and
• the disposable part (3) comprises:
• a container (4) that in turn comprises:
• a hydraulic circuit (17) comprising at least one first tube (21) that channels a perfusion fluid externally pumped to the container (4) to the liver or kidney housed in a central portion (5) inside the container (4),
• a cannula (16) that channels urine or bile outward from the liver or kidney, respectively, to an external reservoir through a first outlet opening in the container (4),
• characterised in that the central portion (5) comprises a lower section (6) which has a height difference with respect to an upper section (7) and the liver or kidney is arranged between said upper section (7) and the lower section (6), so that the perfusion fluid after circulating through the liver or kidney falls into the lower section (6), said lower section (6) thus acting as a reservoir for perfusion fluid.
