Resumo
The study was motivated by the critical importance of sterilization performed by autoclaves for the proper and safe treatment of patients in hospital environments. It aimed to improve the maintenance plan for a Baumer HI VAC MX II B0112 autoclave used for sterilization in a hospital setting, classified as a Category V pressure vessel under NR 13. The methodology included an analysis of the maintenance history (2022–2023), identification of critical components, implementation of predictive maintenance techniques (non-destructive testing and visual inspection), optimization of the maintenance schedule, improvement in inventory management, and the implementation of a data recording and analysis system. The results showed an increase in maintenance performance indicators, with a 23.4% improvement in MTBF (Mean Time Between Failures), rising from 255.5 to 315.22 hours. Additionally, there was a 29% reduction in MTTR (Mean Time to Repair), decreasing from 18.65 to 13.25 hours, and an increase in equipment availability from 92.37% to 95.97%. Improvements included predictive maintenance, schedule optimization based on actual wear, integrated inventory management, and compliance with regulations such as RDC 15. Despite the short post-improvement analysis period (6 months), the project demonstrated potential to enhance operational efficiency, reduce costs, and improve safety. Continuous monitoring, full implementation of the proposed actions, and expansion of the predictive maintenance plan are recommended. The project contributed to the optimization of sterilization processes, positively impacting the quality of patient care and the safety of medical procedures.
