EX VIVO LUNG MECHANICAL PERFUSION CONTROL SYSTEM, METHOD AND APPARATUS

摘要

The present application relates to an ex vivo lung mechanical perfusion control system, method and apparatus. The ex vivo lung mechanical perfusion control system comprises a pipeline circulation apparatus, a power pump device, a flow sensor and a main control device. When receiving a constant-speed operation instruction, the main control device drives the power pump device according to constant rotation speed data corresponding to the constant-speed operation instruction; when receiving a constant flow operation instruction, the main control device acquires, according to the constant flow operation instruction, a flow collected by the flow sensor, and performs digital filtering processing on the flow to obtain the filtered flow; and the main control device performs PID adjustment processing on the filtered flow and a target flow to obtain a processing result, and adjusts the rotation speed of the power pump device according to the processing result. The present application can realize a plurality of perfusion modes of a constant-pump speed mode and a constant-flow speed mode, and each mode can be switched in an easy manner; and by performing data filtering processing and PID adjustment processing on flow data, the present application improves the accuracy of mechanical perfusion control for an ex vivo lung.
