RESUMO
Objective:is toTo detect a new type of micro-injection pump, its flow rate of quality control testing and syringe pump through the comparative analysis, and study its accuracy and stability. Methods:A certain brand of injection flow rate accuracy and stability of drug pumps and syringe pumps were detected by the use of professional Fluke infusion device analyzer and a dedicated infusion line. Results:Compared the injection pump with syringe pump flow rate of errors, a flow rate was 1 ml/h, t. The errordeviation range of micro-injection pump flow rate is larger than the syringe pump, and a flow rate was 25 ml/h and 50 ml/h, both the same, . Wwith drug detection time went on, a flow rate of injection pump has tended to stabilize. After the flow rate is stable, the longer the detection time is, the overall error is smaller. At the time of 15 min, test data are in line with national testing standards. Conclusion:The combination of injection pump and infusion pump, the micro-injection pump can meet the growing demand for clinical departments, and its stability and accuracy can meet the national standards.
