Abstract:
Objective: To design a disinfection system for pipeline of dialysis water that can be automatically controlled so as to improve the disinfection effect, and ensure the health and safety of the operators and patients with hemodialysis. Methods: In the new disinfection system, the manual control was changed to single chip, and the disinfection method was ozone disinfection. In the actual ozone disinfection instrument for the pipeline of dialysis water, through the relationship among solubility, half-life period and temperature of underwater ozone to obtain a simulate relational expression between disinfection time and temperature, and then through single chip to achieve automatic control of disinfection process. Results: Through experimental verification, the system was able to coordinately complete automatic disinfection, emptying and swashing, and the concentration of ozone could meet the requirements of setting. Conclusion: The design can effectively disinfect the pipeline of dialysis water and avoid harm for human body in operation. And the added functions, automatic emptying and swashing, can ensure the pipeline of dialysis water is applied in dialysis cure as soon as possible after the disinfection was completed, and it guarantee the safety of hemodialysis.
