The invention relates to a device for the preservation of a hepatic graft (1) in normothermia comprising a recepta-cle (2) in which said hepatic graft (1) is housed in a preservation solution, an arterial perfusion circuit (3), a portal perfusion cir-cuit (5), at least one flow sensor (7) of a perfusion circuit, and at least one pressure sensor (8) of a perfusion circuit. For the pur-pose of increasing the preservation of the hepatic graft (1), the preservation device additionally comprises an arterial oxygenator (11) connected to the arterial perfusion circuit (3), a portal oxygenator (12) connected to the portal perfusion circuit (5), at least one arterial perfusion pump (9), at least one portal perfusion pump (10), a temperature exchange module (13) configured to main-tain the temperature inside the receptacle (2) in normothermia, and a pressure and flow control device (14).

Linvention porte sur un dispositif permettant la conservation dun greffon hépatique (1) en normothermie, comprenant un réceptacle (2) dans lequel ledit greffon hépatique (1) est abrité dans une solution de conservation, un circuit de perfusion artérielle (3), un circuit de perfusion portale (5), au moins un capteur de débit (7) dun circuit de perfusion et au moins un capteur de pression dun circuit de perfusion. Pour parvenir à augmenter la conservation du greffon hépatique (1), le dispositif de conservation comprend de plus un dispositif doxygénation artérielle (11) connecté au circuit de perfusion artérielle, un dispositif doxygénation portale (11) connecté au circuit de perfusion portale, au moins une pompe de perfusion artérielle (9), au moins une pompe de perfusion portale (10), un module déchange de température (13) conçu pour maintenir la température à lintérieur du réceptacle (2) en normothermie, ainsi quun dispositif de contrôle du débit et de la pression (14).
