Title:
HIGH-STABILITY INTRACRANIAL TEMPERATURE MEASUREMENT AND CALCULATION METHOD AND MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/154951
Kind Code:
A1
Abstract:
A high-stability intracranial temperature measurement and calculation method and measurement device (20). For a thermistor (211) of each model at temperature T0, a resistance value R0 and a characteristic value B of the thermistor (211) are each marked with an error range, that is, for thermistors (211) of the same model, errors of the resistance values R0 and the characteristic values B of the thermistors (211) should be considered during a mass production process; the resistance value of the thermistor (211) at T0 temperature is calibrated and recorded by means of a memory, a measured value is calibrated by a correction formula Rx=Rt1*(R0/Rf), and according to a corresponding relationship curve between unknown temperature Tx and Rx, i.e., Rx=R0*e B*(1/Tx-1/T0), more accurate Tx is obtained if Rx is obtained, wherein Tx is the intracranial temperature. The method and measurement device solve the problem in the prior art of high manufacturing cost and low measurement accuracy of intracranial temperature measurement using a thermistor.
