Abstract: Objective Analyze and conclude the new quality control process, so as to improve the quality control efficiency. Methods Statistical analysis was conducted on the flow rate quality control data of infusion pump in 2020, with a total of 330 times of quality control data. Results The pump with qualified flow rate entered and maintained the qualified state from the third minute, while the pump with unqualified flow rate entered and maintained the unqualified state from the second minute. Conclusion Take the third minute to enter the qualified range and continue for 2 minutes to judge that the flow rate quality control is qualified. The accuracy of this new rule is as high as 100%, and the time of flow rate quality control can be reduced from 60 minutes to 10 minutes, which greatly improves the work efficiency.
