Abstract

PURPOSE:To measure easily and rationally human body temperature, by installing an information circuits generating consecutively a plurality of information sounds informing elapsed times after start of the measurement. CONSTITUTION:When, for temperature measurement, the electric power source is thrown in by a switch 6, a counter 4a in an information circuit 4 starts counting and sums up elapsed time after throwing-in of the source. For every unit time interval after starting of counting, the counter 4a delivers pulses to a code- generating circuit 4b. The circuit 4b is driven by pulses supplied successively and delivers pulses coded corresponding to each elapse time. By these pulses, a sound emitting circuit 4c is driven for generation of information sound.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an electronic thermometer with a function of generating a notification sound.

[Technical background of the invention and its problems]

Body temperature is routinely measured clinically or at home as a vital sign of living organisms. However, conventional glass thermometers have the inconvenience of having to be careful about the measurement time and constantly measuring the temperature. Furthermore, among electronic thermometers that have recently become popular, some display a blinking display or generate a simple notification sound when the temperature is saturated and the change per unit time falls below a set value. However, it is generally difficult to confirm the blinking of the display while measuring temperature, and it is not appropriate to generate a notification sound based on a uniform logic for living organisms with diverse conditions and individual differences. There are many cases where this is lacking, making it impossible to perform highly accurate measurements.

[Purpose of the invention]

The present invention is intended to address the above-mentioned circumstances, and an object of the present invention is to provide an electronic thermometer that can easily and rationally measure body temperature according to individual differences and can perform highly accurate measurements.

[Summary of the invention]

This invention includes a temperature detection circuit that generates an electrical signal according to body temperature, an arithmetic circuit that converts the signal from this detection circuit into a temperature value, a display circuit that displays this temperature value, and a The device is characterized by comprising a notification circuit that sequentially generates a plurality of notification sounds to notify the elapsed time.

〔Effect of the invention〕

According to this invention, it is possible to accurately and easily know the elapsed temperature measurement time, which eliminates the inconvenience of handling conventional glass thermometers, and also provides a rational and accurate method that takes advantage of the usage of glass thermometers. Can perform high temperature measurements.

In particular, by encoding a plurality of notification sounds to ensure identification, and by using the final sound as an alarm sound to distinguish it from other sounds, it is possible to prevent forgetting to turn off the power after temperature measurement is completed.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

As shown in Figure 1, this thermometer includes a temperature detection circuit 1 that generates an electrical signal according to body temperature, an arithmetic circuit 2 that converts this electrical signal into a temperature value, and a display circuit that displays this temperature value. 3, a notification circuit 4 that sequentially generates a plurality of notification sounds indicating elapsed time, a power supply circuit 5 that serves as a power source for these circuits, and a switch 6 that turns on and off the power.

In this thermometer, when the power is turned on by the switch 6 for temperature measurement, the counter 4a of the notification circuit 4 is turned on as shown in FIG.
Counting is started by the pulse shown in a), and the elapsed time after the power is turned on is counted. After a unit time has elapsed from the start of counting, for example, in the case of this embodiment, 1 minute, 2 minutes, 3 minutes, etc. 5 minutes later, the counter 4a generates pulses, and these pulses are supplied to the code generation circuit 4b. .

The code generation circuit 4b is driven by sequentially supplied pulses, and outputs encoded pulses as shown in FIG. is driven and a notification sound is generated.

In this example, a beep occurs after 1, 2, and 3 minutes, respectively.
A beep, beep, beep sound is generated, and after 5 minutes, an intermittent beep, beep, and beep sound is issued as the final sound.

□ Therefore, by listening to these sounds, you can accurately determine the temperature measurement time, allowing you to perform highly accurate measurements.At the same time, you can know when the measurement is finished by the final sound, and open switch 6 to turn on the power. It is possible to block out...

Note that the present invention is not limited to the above-mentioned embodiments, but can be implemented with various modifications without changing the gist.

,・□For example, the encoded notification sound is not limited to the one used in □′ in the above embodiment, and various sounds suitable for identification can be selected.
