A new detection and analysis of flow rate accuracy on a new tracetype micro-injection drug pump and syringe pump flow rate accuracy

目的:对一款新型微量注药泵的流速进行质量控制检测,通过与微量注射泵的对比分析,研究其准确性和稳定性。方法:使用专业的Fluke输液设备分析仪以及指定的输液管路对某品牌注药泵和注射泵的流速精度和稳定性进行检测。结果:从注药泵和注射泵流速误差比较中发现,流速为1 ml/h时,注药泵流速误差范围较注射泵偏大;流速为25 ml/h和50 ml/h时,两者流速误差基本相当;注药泵的流速随着检测时间趋向于稳定,流速稳定后,检测时间越长,总体误差越小;在第15 min时,检测数据符合国家相关检测标准。结论:该微量注药泵结合了输液泵和注射泵的特点,稳定性和准确性均能满足国家相关标准,能够满足临床科室的应用需求。

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.
