Comparison and Discussion of National/Military Standards Related to Flow Measurement of Medical Injection Pump / 中国医疗器械杂志

Medical injection pump is a commonly used clinical equipment with high risk. Accurate detection of flow is an important aspect to ensure its reliable operation. In this paper, we carefully studied and analyzed the flow detection methods of three standards being used in medical injection pump detection in our country. The three standards were compared from the aspects of standard device, flow test point selection, length of test time and accuracy judgment. The advantages and disadvantages of these standards were analyzed and suggestions for improvement were put forward.

A research of quality control method on medical injection pump / 中国医学装备

Objective: To explore the quality control scheme of medical injection pump so as to ensure the usage safety of injection pump in clinical practice and guarantee the accuracy of liquid, and to enhance the medical quality. Method: The quality of micro injection pump should be evaluated through five aspects included of appearance, alarm function, recognition on specifications, mechanical precision and accuracy of flow. And the routine injection interface of injection pump was tested, and two methods that included antitheses and weight method were adopted. Result:After strictly tested a series technique parameters included of the injection speed of pump, mechanical precision and accuracy of flow, all of the measured data were putted into formula to judge whether the pump could meet the criteria. Therefore, the method guaranteed the precision of micro injection pump could meet the national criteria. Conclusion:Hospital should establish archive management and quality control standard for medical injection pump, and routinely carry out calibration and measurement, and keep the normal use of equipment and keep technique indicators of various aspects can achieve requirement, so as to ensure liquid could be accurately infused, and could achieve clinical requirement, and guarantee therapeutic effect.
