The management platform, is also used to predict the Temperature changing of patient, specifically:
Management platform classifies patient according to its illness type and illness stage;
Management platform counts the body temperature of every a kind of patient and variation, specially the average value of the body temperature of statistics patient and
The average value of the changing value in current illness stage;
Manage illness type and illness stage of the platform according to current patents, find the body temperature of corresponding patient average value and
In the average value of the changing value in current illness stage;
The body temperature of the patient predicted by the second formula, second formula are as follows:
Wherein, T is the predicted value to the body temperature of current patents, T0For the body temperature value of current patents, TaFor the classification patient of statistics
Body temperature average value, c be preset regulation coefficient, obtained by statistics, Δ T be count classification patient body temperature variation
The average value of value.
5. system according to claim 4, which is characterized in that
The body temperature acquisition terminal further includes warning reminding unit, and the warning reminding unit includes combined aural and visual alarm;
The warning reminding unit is connect with microcontroller, when patient temperature more than alarm body temperature or triggers preset alarm rule
When then, microcontroller controls warning reminding unit and executes actuation of an alarm, and right by the patient institute of management platform to triggering alarm
The medical staff answered and nurse station alert.
6. system according to claim 1, which is characterized in that
The body temperature acquisition terminal, further includes external fixator, and external fixator and shell are separable structure;
When external fixator is mutually fixed with shell, fixing piece contact surface and shell contact surface are in same plane, the fixation
Part contact surface is the external fixator for contact surface with skin contact, the shell contact surface be shell be used for and skin
The contact surface of skin contact;
The thermal resistance between outside to shell of external fixator is not less than the first preset value;
The bending stiffness along skin surface normal orientation of external fixator is not higher than the second preset value.
