Abstract: An artificial kidney (dialyzer) reprocessing system for washing used artificial kidneys includes a high-pressure water supply system providing RO water and chemical solutions for washing and sterilization so as to make artificial kidney (dialyzers) be reused. The feature of the device is that an ozone water device is connected to an high-pressure water supply system in parallel for providing the artificial kidney (dialyzer) reprocessing device ozone water for washing and sterilization. The problem of chemical residuals in the system can also be avoided.
