Estimating the term…
The present invention discloses an afterload device for ex situ heart perfusion, which includes an afterload energy storage module, a pressure regulation module and two flow rate regulators that are connected through a conduit. The afterload energy storage module includes a rigid closed container and a flexible container. The perfusion fluid flows into the flexible container from one side thereof through the conduit, and the perfusion fluid flows out from the flexible container at another side thereof as the flexible container is subjected to the action of the medium pressure in the rigid hermetic container. The pressure regulation module includes two pressure regulation valves and a compressible-medium source, for regulating the pressure range within the rigid hermetic container to be always maintained between the set diastolic pressure and the set systolic pressure.
An afterload device for ex situ heart perfusion, comprising an energy storage module, a pressure regulation module and two flow rate regulators, wherein the energy storage module comprises a flexible container and a rigid hermetic container filled with compressible media, the flexible container is placed in the inner cavity of the rigid hermetic container and connected to the two flow rate regulators via a conduit;
