Abstract：The accuracy of the infusion pump's flow rate played an critical role in the clinical treatment. There are two testing methods at present: the volumetric methods and the weighing methods. In this paper, the principle, instrument and testing details of the two methods were expounded. Additionally, the two methods were respectively adopted to test the flow rate of a certain brand infusion pump. The results indicated that, the volumetric method was featured with high testing speed, high efficiency, low sensitivity to the small flow in contrast with the weighing method’s characteristics of low testing speed, low efficiency, high sensitivity to the small flow. The volumetric method was applicable for on-site testing since it was easily affected by multiple factors; while, the weighing method could be used for testing of the bolus and was applicable for arbitration testing. For strict control of the quality of the infusion pump, it is recommended to adopt the weighting method for registration testing.
