Abstract：Objective To practice and discuss of personalized preventive maintenance mode of hemodialysis machine using PDCA
to continuously improve content and cycle. Methods A total of 30 blood dialyzer samples were selected, which were mainly
from two major imported brands. Among them, 15 used the traditional fixed content and cycle preventive maintenance mode, the
other 15 used PDCA to realize the personalized preventive maintenance mode of continuous improvement of content and cycle,
and the maintenance cycle was three years. Then, the failure rates and failure types of the equipment within three years were
compared. Results After the using of PDCA to realize the personalized preventive maintenance mode of continuous improvement
content and cycle, the failure rate of the hemodialysis machine was lower, which could effectively reduce improper use, sensor
adjustment misalignment, and accessory damage failure. Conclusion Using PDCA to continuously improve the content and cycle
of hemodialysis machine personalized preventive maintenance mode has better security effect. It is a progressive and promising
preventive maintenance mode.
