Body temperature measureing system and data reading device as well as relevant drive and control method

Abstract

In a body temperature measuring system, there is realized body temperature measurement based on a temperature resolution of 0.01OC, and there is made a reduction in electric power consumed by a data reading device. More specifically, disclosed is a clinical thermometer which is a body temperature measuring system provided with a body temperature tag (113) and a data reading device (101). A processing unit (115) in the body temperature tag (113) is provided with a power supply circuit, a semiconductor body temperature sensor which detects a band gap voltage, and a memory device which memorizes calibration data for calibrating the band gap voltage detected. The aforementioned processing unit (115) is configured in such a way that the aforementioned band gap voltage detected in conjunction with the start-up of the aforementioned power supply circuit is transmitted, via an antenna unit (114), together with the aforementioned calibration data. The data reading device (101) is provided with an excitation means and a detection means which detects a magnetic field change caused by excitation. The aforementioned data reading device (101) is characterized in that when a magnetic field change is detected, the electric power level in the excitation means is changed.

Description

technical field

[0001] The present invention relates to a body temperature measurement system including a thermometer for measuring the body temperature of a subject, and a data reading device for reading data from the thermometer. In particular, it relates to a data reading device and a drive control method thereof for reading data from a thermometer having a body temperature tag with excellent measurement accuracy at a temperature measurement range of 32°C to 42°C. Background technique

[0002] Conventionally, in hospitals, etc., patients' body temperatures were regularly measured and the measurement results were managed. Usually, when measuring the body temperature, such an operation is performed: the thermometer is placed on the measurement site of the subject, and the thermometer is kept in a static state for a certain period of time before the measurement is completed. In addition, after the measurement is completed, the measurer confirms the measurement result and re...
