This invention belongs to the field of medical device technology, specifically referring to an implantable pleural shunt drainage system, including a pleural shunt drainage device and a control system. The pleural shunt drainage device includes an implantable device, an inflow catheter, and an outflow catheter. The inflow catheter is placed into the pleural cavity, and the outflow catheter is placed into the bladder cavity or peritoneal cavity. The implantable device incorporates a positive displacement micropump, an inlet pressure sensor, an outlet pressure sensor, and an ambient pressure sensor. Before formal pumping, the control system performs low-volume diagnostic pumping and determines the inlet fluid replenishment status based on the effective drainage volume after short and long pauses, the recovery of inlet pressure, and the recovery of respiratory waveform. Based on this, it switches between intermittent pumping, stops pumping, or allows restricted drainage, and only accumulates the confirmed effective drainage volume. This invention can reduce ineffective pumping and accidental drainage.
