长期负荷对双道微量注射泵的影响

The Effect of Long-Term Load on Duplex Microsyringe Pump

目的探究长期负荷对双道微量注射泵的影响。方法回顾性分析2023年6—9月医院的92台双道微量注射泵的使用记录,按照使用方法不同分组,正常规范应用的双道微量注射泵为对照组,常超时及注射过量使用的双道微量注射泵为观察组,每组46台。比较两组流速精度准确性、压力传感器准确性、自动报警系统故障率及安全性。结果观察组流速精度准确性、压力传感器准确性低于对照组,差异有统计学意义(P<0.05);观察组自动报警系统故障率高于对照组,差异有统计学意义(P<0.05);观察组安全性低于对照组,差异有统计学意义(P<0.05)。结论长期负荷会导致双道微量注射泵流速精度准确性、压力传感器准确性降低,自动报警系统故障率升高,进而降低使用安全性。

Objective To explore the effect of long-term load on duplex microsyringe pump.Methods With the retrospective analysis of the usage records of 92 duplex microsyringe pumps in hospitals from June to September 2023,according to the different use methods,the duplex microsyringe pumps used in normal practice were divided into control group,and the duplex microsyringe pumps used in frequent timeout and excessive injection were divided into observation group,with 46 sets in each group.The accuracy of flow velocity and pressure sensor,automatic alarm system failure rate,and safety were compared between the two groups.Results The accuracy of flow velocity and pressure sensor in the observation group was lower than that in the control group,and the difference was statistically significant(P<0.05);The failure rate of the automatic alarm system in the observation group was higher than that in the control group,and the difference was statistically significant(P<0.05);The safety of the observation group was lower than that of the control group,and the difference was statistically significant(P<0.05).Conclusion Long term load can lead to a decrease in the accuracy of the flow rate and pressure sensor of the duplex microsyringe pumps,an increase in the failure rate of the automatic alarm system,and a decrease in the safety of use.
