The invention relates to a control system, method and device for in-vitro lung mechanical perfusion. The control system for in-vitro lung mechanical perfusion comprises a pipeline circulation device,power pump equipment, a flow sensor and main control equipment. When receiving a constant speed operation command, the main control equipment drives the power pump equipment according to constant speed data corresponding to the constant speed operation command; when receiving a constant flow operation instruction, the main control equipment acquires a flow collected by the flow sensor according tothe constant flow operation instruction, and carries out digital filtering processing on the flow to obtain a filtered flow; and the main control device carries out proportional-integral-derivative (PID) adjustment processing on the filtered flow and a target flow to obtain a processing result, and adjusts the rotating speed of the power pump equipment according to the processing result. According to the invention, a plurality of perfusion modes such as a constant pump speed mode and a constant flow speed mode can be realized, and switching is convenient. Through data filtering processing andPID adjusting processing on flow data, control accuracy of in-vitro lung mechanical perfusion is improved.
Description
technical field [0001] The present application relates to the technical field of mechanical perfusion, in particular to a control system, method and device for mechanical perfusion of isolated lungs. Background technique [0002] Mechanical perfusion is a way to preserve and transport organs (such as isolated lungs). After the organ is harvested, its own blood vessels are connected to the mechanical perfusion system of the organ. At the same time supply the isolated organs with oxygen and nutrients. During the mechanical perfusion process of isolated lungs, the accuracy of controlling perfusion parameters directly affects the quality of isolated lungs. [0003] During the implementation process, the inventor found at least the following problems in the traditional technology: the traditional lung perfusion system has a single control mode and low perfusion accuracy. Contents of the invention [0004] Based on this, it is necessary to provide a mechanical perfusion contro...
