Abstract
The utility model discloses a numerical-control constant-pressure perfusion experiment device, which comprises a controller, a pressure sensor, a micro air pump, an air storage cylinder and a liquid storage cylinder. The micro air pump, the air storage cylinder and the liquid storage cylinder are sequentially connected through pipelines. A throttling valve and a check valve are arranged on a pipeline which connects the micro air pump and the air storage cylinder. The controller is respectively connected with the micro air pump and the pressure sensor through circuits and controls the micro air pump and the pressure sensor. The pressure sensor is arranged on the liquid storage cylinder. A liquid outlet pipe is connected onto the liquid storage cylinder. A throttling valve and a control valve are arranged on the liquid outlet pipe. When the numerical-control constant-pressure perfusion experiment device works, the pressure sensor measures a pressure value in the liquid storage cylinder, and the controller compares the pressure value with a preset pressure value and controls the micro air pump to work. When a constant-pressure perfusion experiment is conducted, the control valve is opened, perfusion liquid flows out of the liquid storage cylinder and relevant subsequent operation is conducted. The numerical-control constant-pressure perfusion experiment device can be used for teaching of medical basic experiment courses and scientific research projects, and has the advantages of small volume, simplicity in operation, convenience in use, low cost and the like.
