Title:
INTRACRANIAL TEMPERATURE MEASUREMENT AND CALCULATION METHOD, AND INTRACRANIAL TEMPERATURE MEASUREMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/154952
Kind Code:
A1
Abstract:
An intracranial temperature measurement and calculation method, and an intracranial temperature measurement apparatus (20). With regard to each type of thermistor (221) at a temperature T0, due to the fact that resistance values R0 and characteristic values B of the thermistors (221) are all marked with error ranges, during a batch production process, errors in the resistance value R0 and the characteristic value B of each of the thermistors (221) need to be considered. By means of calibrating the resistance values of the thermistors (221) at the temperature T0 and recording same by means of calibrating a resistor (231), measured values are calibrated by means of a correction formula: Rx = Rt1*(R0/Rf), and under the condition of obtaining Rx, more accurate Tx is obtained by means of a correlation curve of Tx and Rx, i.e. Rx = R0*e B*(1/Tx-1/T0), wherein Tx is an intracranial temperature. The temperature measurement and calculation method, and the temperature measurement apparatus solve the problems in the prior art of high manufacturing costs, low measurement precision and a complicated apparatus structure when an intracranial temperature is measured by means of thermistors.
