Abstract

The invention relates to a system, a method and a device for controlling liver perfusion. The system comprises a first centrifugal blood pump subsystem and a second centrifugal blood pump subsystem, wherein the first centrifugal blood pump subsystem is connected with a liver artery and is used for carrying out pulse type blood supply; the second centrifugal blood pump subsystem is connected with a portal vein and is used for carrying out constant blood supply on the portal vein. A pulse blood pressure data treatment mode is carried out on liver artery perfusion line blood pressure, a constant blood pressure data treatment mode is carried out on portal vein perfusion line blood pressure, and a blood supply mode approximate to impulse blood supply of a real heart for the liver artery and a blood supply mode approximate to stable blood supply of a real portal vein in a human body for the portal vein are respectively generated by using blood pressure as a main control parameter and blood flow as an auxiliary monitoring parameter. The system, the method and the device for controlling the liver perfusion, disclosed by the invention, are beneficial for increasing the repairing and preserving effects on marginal donor organs such as liver and reducing a liver reperfusion injury risk.

Description

technical field [0001] The present invention relates to the technical field of mechanical perfusion, in particular to a liver perfusion control system, method and device. Background technique [0002] Mechanical perfusion is a way to preserve and transport organs. After the organ is harvested, its own blood vessels are connected to the mechanical perfusion system of the organ. The system will continuously perfuse the perfusate to the isolated organ during the organ preservation and transport phase, and supply oxygen to the isolated organ at the same time. and nutrients etc. [0003] Most liver perfusion systems are modified by extracorporeal membrane oxygenation (ECMO, extracorporeal membraneoxygenation) system to perfuse the liver. The traditional ECMO system mainly uses a rolling pump for perfusion and blood supply, which can provide sufficient power to achieve the blood flow and blood pressure required by the organ (heart). However, there are great differences between l...
