We have developed medical infusion pump in compliance with EMC requirements. The applied concepts are(1)the safety against the interactions from electrosurgical knife or mobile telephone, (2)the complete waterproof configuration so as to be soaked and washed in disinfectant. The given specifications and features are finger pump with a wide flow rate range, infusion volume program and drip volume calibration, and power source range of 85〜264V AC, battery operating function. It also provides with such alarm functions as air detector. A specific photodiode, strong against electromagnetic noise, is applied in drip detector to meet EMC requirements. The pump has further features of multilayer CPU board, advanced surface treatment of non electrolytic nickelplating on copper plating base and dual insulating configuration of electromagnetic inducting connection for power unit, etc. As the results, it was found in the tests on the samples that the pump complies with the EMC requirements, and has no reciprocal effect from the simultaneous use of electrosurgical knife or mobile telephone.
