Abstract
According to the parameters of main indicators of pressurization device of blood transfusion and infusion,the calibration method was designed based on key technical parameters,which included pressure indication error,pressure output velocity,pressure release velocity,pressure bag airtightness,and overpressure protection. Three used pressurization devices of blood transfusion and infusion with different brands (labeled as Test Equipment A,Test Equipment B,and Test Equipment C) were selected to conduct calibration in the hospital,so as to assess the feasibility of calibration method,and to provide technique reference for evaluating the parameters of the performance. The calibration methods of pressurization device of blood transfusion and infusion were formulated from five aspects:pressure indication error,pressure output velocity,pressure deflation velocity,pressure bag airtightness and overpressure protection of pressurization device of blood transfusion and infusion. The results showed that the calibration method for pressurization device of blood transfusion and infusion,and the pressure and time recorder equipped with standard instrument of calibration can effectively calibrate the performance parameters of pressurization device of blood transfusion and infusion. The recorded data can meet the maximum limit output value of the manufacturer's technical requirements. The calibration method of pressurization device of blood transfusion and infusion can improve the metrological traceability system of such equipment,and ensure the safety and effectiveness of equipment performance,and enhance product quality,and reduce risks of clinical use,and guarantee medical safety.
