Pressure control device for arterial perfusion of isolated vascular

The invention discloses a pressure control device for the arterial perfusion of an isolated vascular. The device comprises a perfusate circulatory system, a gas system, and a pressure detection and control system. The perfusate circulatory system comprises a sealed pipe; the sealed pipe is connected to a pipeline which forms a circulatory pipeline with the sealed pipe; the end of the pipeline where the perfusate inflows is inserted below the liquid level of the sealed pipe; and a peristaltic pump and the isolated vascular are arranged on the pipeline. The gas system comprises an air inlet pipeand an air outlet pipe which are connected to a cavity part of the sealed pipe, wherein the air inlet pipe is connected to an air pump and a gas flow regulating valve, and the air outlet pipe is connected to an electromagnetic exhaust valve and a gas flow regulating valve. The pressure detection and control system comprises an air pressure sensor inserted into the cavity part of the sealed pipe,a control system connected
