Abstract：Objective The information system of closed-loop management of metrology of medical equipment should be strengthened
to improve the efficiency of metrological management and ensure the safety of clinical medical equipment. Methods Based on
the whole life cycle management concept of medical equipment, the “double closed-loop” management system of metrology was
designed, and the information system of closed-loop management of metrology of medical equipment was constructed by means
of information technology. In 2018, manual management was used as the control group, and in 2019, the information system
management was used as the experimental group. SPSS software was used for statistical analysis of the number of metrology and
metrological days of mercury sphygmomanometer, and for statistical analysis of the recording time of metrological certificate of 200
randomly selected devices. Results The coverage rate of metrology increased from 95.3% (control group) to 100% (experimental
group), and the difference between the two groups was statistically significant (χ2=13.235, P<0.01)| the efficiency of metrology
was shortened from a large number of devices concentrated in 2 d (control group) to a large number of devices concentrated in 1 d
(experimental group), and the difference between the two groups was statistically significant (χ2=338.002, P<0.001)| the recording
time of metrological certificate is reduced from 69.66 to 12.74 s, and the difference between the two groups was statistically
significant (t=72.695, P<0.001). Conclusion The application of the information system can effectively and comprehensively
improve the efficiency of the metrological management of medical equipment and reduce the potential safety hazards of medical
equipment.
