摘　　要：目的:探讨注射泵质量控制的方法,分析注射泵质量控制的影响因素。方法:依据国家校准规范,利用INFUTEST 2000E双通道输液泵分析仪对注射泵的流量基本误差和阻塞报警误差进行检测。结果:注射器规格型号、注射速度及注射介质均对注射泵精确度测试有影响;注射速度设置越低,流量测试误差越大,阻塞报警测试误差越小;注射速度设置越高,流量测试误差越小,阻塞报警测试误差越大;流量测试合格率较高,阻塞报警测试合格率较低。结论:注射泵质量控制应遵循风险可控原则,做好医院医疗设备的质量控制工作。Objective:To discuss the quality control method of injection pump and analyze the factors that affect the quality control of injection pump.Methods:Flow error and blocking alarm error were tested by the INFUTEST2000E dual-channel infusion pump analyzer according to the national calibration specifications.Results:The syringe specifications,injection speed and injection solvent could influence the test for accuracy of injection pump.The lower injection speed set,the bigger flow test error was,while the smaller the blocking alarm test error was.On the other hand,the higher the injection speed set,the smaller the flow test error was and the bigger the blocking alarm test error was.Besides,the higher qualified rate of flow test was,the lower the qualified rate of blocking alarm test was.Conclusion:The quality control of injection pump should abide by the principle of controllable risk,and should not pursuit too much accuracy.
