Abstract
Hemodialysis devices are vital medical equipment which is directly responsible for the patient’s life, used to treat kidney failure. In this paper, the reliability of the Hemodialysis machine was analyzed using a Weibull distribution approach. The weibull distribution is adopted for this analysis, with clear and simplified steps, enabling hospital maintenance department to use the results to develop an inspection/maintenance model, and can be implemented in healthcare facilities in order to guarantee the safety and efficiency of dialysis processes. A statistical analysis of the failure data is adopted to harness the failure and repair data of the machine. From the failure history, the scale and the shape parameters of the Weibull distribution were estimated using a linearization of the cumulative density function. The efficiency of the used method is illustrated by the quality fitness indices. The question of the reliability and the failure rate is treated in order to develop an efficient tool for the medical equipment monitoring.
