Temperature control method and system of temperature therapeutic instrument

Abstract

The invention relates to a temperature control method and system of a temperature therapeutic instrument. The PWM _ ALL signal is calculated according to the current temperature and the target temperature of the treatment water. Before the PWM _ ALL signal is outputted, the PWM _ ALL signal is compared with the maximum limit value PWM _ ALL _ MAX. When the PWM _ ALL is larger than the maximum limit value PWM _ ALL _ MAX, the PWM _ ALL is enabled to be equal to PWM _ ALL _ MAX, and then a PWM _ ALL signal is outputted to a refrigerating / heating module to perform refrigeration or heating. If thecurrent temperature is close to the room temperature, the temperature treatment has a gentle temperature change rate, and discomfort of a patient is prevented; and if the current temperature is in alower or higher interval, the temperature treatment has a higher temperature regulation speed so that the requirement of quick temperature regulation can be met. Therefore, the temperature adjusting requirement and the comfort level of the patient are both considered in the temperature treatment process of the temperature treatment instrument.

Description

technical field [0001] The invention relates to the technical field of medical temperature therapy, in particular to a temperature control method and system of a temperature therapy instrument. Background technique [0002] Existing trauma patients, patients with internal bacterial or viral infection, patients with internal organ function, etc., in clinical treatment, because of human body function or treatment needs, all need low temperature auxiliary treatment or high temperature auxiliary treatment, so temperature therapy equipment is produced. [0003] But there is following defect in existing temperature therapy instrument when using: [0004] When the current temperature is heating or cooling near room temperature, the temperature adjustment speed is very fast, but if the current temperature is in a lower or higher range, the temperature adjustment speed is relatively slow. If a cooling and heating module with higher power is used, the treatment temperature can be rea...

AI Technical Summary

Problems solved by technology

If a cooling and heating module with higher power is used, the treatment temperature can be reached quickly, but too fast a temperature change near the room temperature will cause discomfort to the patient; if a cooling and heating module with a lower power is used, it will not cause discomfort to the patient , but it takes a long time to reach the therapeutic temperature
