Description
Technical field
The present invention relates to a kind of infusion tube automatic temperature control heating technology, specifically a kind of infusion tube automatic temperature control heating
System and its control method belong to medical nursing fixture technology field.
Background technique
Clinically there is some the case where need to being heated to input liquid, such as: first, many critical patients can go out
Existing enteral nutrition does not tolerate, and the temperature of nasal feeding liquid, speed, concentration etc. influence the tolerance of patient, at this point, adding to nutrient solution
Heat is to improve one of the measure of tolerance.Second, it is to maintain body items physiological function that human body, which keeps normal thermostasis,
Basic guarantee, but patient is during surgery, easily occurs hypothermia phenomenon for various reasons, constitution critical for the state of an illness it is weaker or
The variation of the patients such as person old man, children, body temperature are seriously affected to body or even threat to life, generally requires in art a large amount of quiet
Arteries and veins infusion or blood transfusion, practice have shown that, the low liquid of a large amount of input temps can induce shiver with cold, easily cause hypothermia, even result in
