Methods Through the strict rules for management of dialyzers, the training for nurses working in hemodialysis center, and the enforced responsibility and technical abilities of the technicians, passive repair after breakdown of dialyzers can be changed to periodic maintenance and preventive repair before the presence of troubles in dialyzers. Results
After the implement of periodic maintenance and preventive repair, the breakdown rate of dialyzers reduced significantly, the cost for repair and performance decreased, and daily work in hemodialysis center could be carried out more efficiently.
