Embodiment Construction

[0052] The electronic thermometer of the present invention will be described in detail below with accompanying drawings.

[0053] figure 1 It is a schematic block diagram for explaining the schematic structure of the electronic thermometer of this invention. exist figure 1 Among them, the electronic thermometer 1 has: a measurement control circuit 2, a sensor 6 for detecting body temperature, a display device 10 for performing the measured body temperature or other displays, a notification device 9 for notification action, and an output drive notification device. A driving device 8 for driving a signal, a switching device 7 such as a power switch or an operation switch.

[0054] The measurement control circuit 2 is for the measuring device 3 measuring the body temperature according to the detection signal of the sensor 6 composed of thermistor and other thermal elements, the measuring operation of the measuring device 3, and the reporting operation of the driving device 8 an...

Abstract

An electronic clinical thermometer includes a control circuit (4) which controls operation timing according to the operations of a measurement device (3) and a notification device (9) so that the measurement operation and the notification operation will not be performed simultaneously, thereby preventing lowering of the measurement accuracy due to battery voltage lowering. The electronic clinical thermometer (1) includes the measurement device (3) for measuring a body temperature, a drive device (8) for recording the notification data, the notification device (9) for performing notification by a drive signal formed according to the notification data, and the control circuit (4) for controlling the measurement operation and the notification operation. The control circuit (4) performs control so that the operation timing of the measurement device (3) is shifted from the operation timing of the notification device (9) according to their operation states so as to prevent simultaneous operations of the measurement and notification. Thus, in the electronic clinical thermometer performing notification operation, it is possible to prevent simultaneous execution of the measurement operation and notification operation, which in turn prevents measurement accuracy lowering due to battery voltage lowering.

Description

technical field [0001] The invention relates to an electronic thermometer. Background technique [0002] The electronic thermometer is configured to measure body temperature with a thermal sensor, detect an equilibrium temperature considered to be body temperature, and report and display it. Such an electronic thermometer automatically judges the end of the measurement at the time of body temperature measurement. When it is judged that the measurement is over, it notifies the end of the measurement and displays the detected temperature as the body temperature. Therefore, it can perform the measurement quickly compared with the mercury electronic thermometer. [0003] As methods for judging the end of the measurement, there have been proposed methods for judging the end of the measurement when it is detected that the measured temperature remains constant for a predetermined period, for judging the end of the measurement when a predetermined time counted by a timer has elapsed...
