Abstract

An organ preservation system includes an organ container, an organ holder, a liquid supply tube, a drainage tube, and a pressure regulator. The organ container has a closed organ preservation space. The organ holder holds an organ in the organ preservation space. The liquid supply tube supplies a liquid to the organ. The drainage tube drains the liquid from the organ. The pressure regulator regulates air pressure in the organ preservation space. The organ container includes first to third connectors providing communication between the organ preservation space and an exterior space. The first, second, and third connectors are detachably connected to a liquid supply tube, a drainage tube, and a suction tube, respectively. When the organ is preserved ex vivo while being perfused with the liquid, the organ can be connected with ease to the tubes, and this ensures hermetical sealing of the space where the organ is preserved.

Dependent claims

An organ preservation system for preserving an organ ex vivo while perfusing said organ with a liquid, the organ preservation system comprising:

an organ container in which a closed organ preservation space can be formed;
an organ holder that holds said organ in said organ preservation space;
a liquid supply tube that supplies a liquid to said organ held by said organ holder;
a drainage tube that drains a liquid out of said organ held by said organ holder;
and
a pressure regulator that regulates air pressure in said organ preservation space,
wherein said pressure regulator includes:
a pressure-reducing mechanism that is provided outside said organ container and sucks gas from said organ preservation space through a suction tube, and
said organ container includes:
a first connector detachably connected to said liquid supply tube and providing communication between said organ preservation space and an exterior space outside said organ container;
a second connector detachably connected to said drainage tube and providing communication between said organ preservation space and said exterior space;
and
a third connector detachably connected to said suction tube and providing communication between said organ preservation space and said exterior space.
