Development of Automatic Calibration System and its Application in Accuracy Correction of Surgical Blood Supply Pump
In order to solve the problems of slow data processing,temperature deviation,poor detection accuracy and low cali-bration efficiency in automatic blood pump calibration,an automatic blood pump calibration system for obstetric operation based on modified algorithm is designed.The average liquid delivery flow of the blood pump is calculated by measuring the volume change of the liquid in the glass container and the time consumed.Based on this principle,a system is designed,the repeatabili-ty and error of the experimental data are analyzed,and the calibration conclusion is made.The results show that the relative er-ror of the system is less than 2％,which meets the industry specification of no more than 8％.The system can measure the ac-curacy under various flow conditions,and the dual channel form can meet the needs of simultaneous calibration of multiple blood supply pumps.
