An automatic control method for disinfection of hemodialysis machines in plateau areas

Abstract

The invention discloses an automatic control method for disinfection of a hemodialysis machine in a plateau region, calculates the boiling point of the disinfectant liquid under the air pressure value according to the air pressure value, and controls the temperature of the disinfectant liquid at a temperature control point slightly lower than the boiling point, in the disinfection During the process, the temperature of the end of the pipeline of the disinfectant is collected, the concentration of the disinfectant is adjusted according to the temperature of the end of the pipeline, and the disinfection time is adjusted according to the temperature of the end of the pipeline and the concentration of the disinfectant. The disinfection device automatically performs the temperature control point, concentration and disinfection time according to the temperature. On the other hand, the minimum disinfection time can also be set as required. The concentration of the disinfectant is adjusted according to the shortest disinfection time and the end temperature of the pipeline. The disinfection device automatically disinfects according to the temperature control point, concentration and the set minimum disinfection time. The invention discloses an automatic control method for disinfection of a hemodialysis machine in a plateau region, which can automatically adjust the temperature, concentration and disinfection time of the disinfectant according to the air pressure value and the ambient temperature, thereby ensuring the disinfection effect and improving the disinfection efficiency.

Description

Technical field [0001] The invention relates to the medical field and the blood purification field, in particular to an automatic control method for disinfection of a hemodialysis machine in a plateau area. Background technique [0002] The patient's blood is processed during the use of the hemodialysis machine, so after each treatment, the liquid pipeline of the hemodialysis machine must be cleaned and disinfected. At present, there are two main disinfection methods commonly used, citric acid high-temperature disinfection (chemical heat disinfection) and peracetic acid disinfection (chemical disinfection). [0003] In the process of citric acid high-temperature disinfection, the citric acid needs to be diluted and heated to above 80°C to achieve the disinfection effect. In high altitude and cold areas, due to factors such as high altitude, low air pressure, and low temperature, the maintenance of disinfectant temperature and the heating of disinfectant temperature have problems s...
