Abstract：Objective To study on the application of blocking alarm pressure measurement and its uncertainty assessment in the
quality control of medical syringe pumps. Methods The blocking alarm pressure of the medical syringe pumps was measured
under standard environmental condition, and the uncertainty was evaluated according to JJF 1059.1-2012. The quality of the
medical syringe pumps was comprehensively evaluated based on the uncertainty. Results The uncertainty assessment of the
blocking alarm pressure measurement results could be used to reasonably evaluate the quality performance of the medical syringe
pumps, and provide guidance for the medical equipment engineering department to control the quality of the medical syringe
pumps. Conclusion The analysis and assessment of the uncertainty of the blocking alarm pressure of medical syringe pumps is
an effective quantitative method for scientific quality control. This method can be used as reference for the quality control of other
medical measuring devices (such as monitors and ventilators).
