Objective To develop an intelligent wound therapeutic instrument based on active instillation and negative pressure suction.Methods SCM coordinated peristaltic pumps, solenoid valves and pressure receptor to infuse perfusate into the wound and retained it for a period of time. The perfusate then was eliminated by negative pressure and the wound was kept in the state of negative pressure. The instrument could give out alarm in case of bad tightness, over-high pressure and blocked negative-pressure pipeline.Results Peristaltic pump and central negative pressure were involved in to complete wound perfusion and irrigation, with perfusate controlled quantitatively and negative pressure kept reliable. The pressures in the wound and pipeline could be monitored at real time by the pressure receptor, and timely alarm was implemented when unexpected conditions occurred.Conclusion The instrument behaves well in automation, intelligence and safety, and thus is worth popularizing clinically.
