In order to help many patients to excrete various secretions of fluid which is accumulated in the abdominal cavity after operation accurately and stably, a negative pressure aspirator based on embedded system is proposed. The system consists of the bareceptor, gravity sensing system, PH value sensor, electromagnetic valve and membrane pump. By detecting the pressure of abdominal cavity, the system regulates the drainage process. At the meantime, the system measures and calculates various parameters of secretion of fluid. After function test, the system controls the drainage process dynamically and measures parameters of secretion of fluid accurately. The system is proved to be stable and reliable through function test.
