Automatic control method for disinfection of hemodialysis machine in plateau area

Abstract

The invention discloses an automatic control method for disinfection of a hemodialysis machine in a plateau area. The boiling point of disinfectant under the air pressure value is calculated according to the air pressure value, the temperature of the disinfectant is controlled to be a temperature control point slightly lower than the boiling point, the pipeline tail end temperature of the disinfectant is collected in the disinfection process, the concentration of the disinfectant is adjusted according to the pipeline tail end temperature, then, the disinfection time is adjusted according to the pipeline tail end temperature and the concentration of the disinfectant, and a disinfection device carries out disinfection automatically according to the temperature control point, concentration and disinfection time; on the other hand, the shortest disinfection time can be set as needed, the concentration of the disinfectant is adjusted according to the shortest disinfection time and the pipeline tail end temperature, and the disinfection device automatically carried out disinfection according to the temperature control point, the concentration and the set shortest disinfection time. According to the automatic control method for disinfection of the hemodialysis machine in the plateau area, the temperature, concentration and disinfection time of the disinfectant can be automatically adjusted according to the air pressure value and environment temperature, the disinfection effect is ensured, and disinfection efficiency is improved.

Description

technical field [0001] The invention relates to the fields of medical treatment and blood purification, in particular to an automatic control method for disinfection of hemodialysis machines in plateau areas. Background technique [0002] During the use of the hemodialysis machine, the patient's blood will be processed, so after each treatment, the liquid pipeline of the hemodialysis machine must be cleaned and disinfected. At present, there are mainly two commonly used disinfection methods, citric acid high-temperature disinfection (chemical heat disinfection) and peracetic acid disinfection (chemical disinfection). [0003] In the process of citric acid high-temperature disinfection, it is necessary to dilute citric acid and heat it above 80°C to achieve the disinfection effect. In the plateau alpine region, due to factors such as high altitude, low air pressure and low temperature, the maintenance of the disinfectant temperature and the heating of the disinfectant temper...
