Abstract:
Objective:To establish safety objectives and strategies for power distribution of medical equipment to minimize the hazard of electrical switching to medical equipment.Methods:Based on the Hazard Analysis and Risk Assessment(HARA)method,the equipment hazard factors analysis and risk assessment were conducted for electrical switching from the perspective of medical equipment safety management.The Deming Cycle(PDCA)closed-loop management process was adopted to formulate refined the medical equipment power distribution safety objectives and response strategies.Results:In 2023,a total of 6 equipment failures occurred during the two periodic electrical shutdown operations carried out in the hospital's power distribution room,which was significantly lower than the average of 20.4 failures caused by electrician shutdowns from 2018 to 2022,and zero failure in Level I load department and other high-risk areas.Conclusion:The objective and strategy of power distribution safety of medical equipment are highly targeted and implemented,which is an effective way to implement the life cycle fine management of medical equipment.
