摘要
目的:设计一种可自动控制的透析用水管道消毒系统,在提高消毒效果的同时保障操作人员和透析患者的健康和安全。方法:基于温度控制的透析用水管道消毒系统,将原来的手动控制改为由单片机控制,选择臭氧消毒方式,通过臭氧在水中的溶解度、半衰期和温度间的关系,在实际的透析用水管道臭氧消毒装置中模拟得到消毒时间和温度的关系式,并接入单片机,实现消毒过程的自动控制。结果:经过实验验证,本系统能够协调完成自动消毒、排空和冲洗动作,臭氧浓度检测达到设定要求。结论:可自动控制的透析用水管道消毒系统的设计可对透析用水管道进行有效消毒,避免了人工操作时对人体的伤害,增设的自动排空和冲洗功能可在消毒完成后尽快用于透析治疗,保证血液透析治疗的安全。
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.
