Flushing aspirator system for monitoring pressure in body cavity, control method and medium

The invention discloses a flushing aspirator system for monitoring pressure in a body cavity, a control method and a medium, and the system comprises a body cavity pressure measurement module which is used for obtaining the pressure in the body cavity and sending the pressure to a control module; the control module is used for comparing the received pressure in the body cavity with a preset threshold value of the pressure in the body cavity, generating a control signal including the rotating speed of a peristaltic pump motor according to the difference ratio of the pressure in the body cavity to the pressure in the body cavity, and sending the control signal to the peristaltic flushing module; wherein a mapping relation between a difference value proportion and a motor rotating speed increasing proportion or a motor rotating speed decreasing proportion is pre-configured in the control module; the peristaltic flushing module is used for receiving the control signal and performing peristaltic flushing according
