A device for the measurement of tympanic temperature with non-invasive and zero-heat flux technology

摘要

The present invention relates to a tympanic membrane temperature measuring apparatus, and more particularly, to a tympanic membrane temperature measuring apparatus which can be used as a portable device using a battery because it is inserted into the external ear canal 90 and is driven with low power.A first sensor (10) is installed at a predetermined distance from an eardrum to measure a temperature near the eardrum. A second sensor 20 installed at a predetermined distance from the first sensor 10 in the direction of the entrance of the external ear canal 90 (external auditory meatus) to measure the temperature; A heating wire (30) surrounding the second sensor (20) and supplying a heat quantity to the second sensor (20); And an MCU (microcircuit unit) 40 for sensing a temperature difference between the first sensor 10 and the second sensor 20 to supply electricity to the heat wire 30.
