Abstract

PURPOSE:To measure exactly a body temperature, and to grasp its thermometric time by turning on or off a display at every specified time interval, or after a set time. CONSTITUTION:A time setting shifting circuit 5 can set the time to a desired set time of 1T through 10T by an input of a switch 3. When the time is set to 10T, a 10T terminal 26 of the circuit 5 becomes an H level and a selecting gate 6 becomes an active state. Subsequently, counter outputs 21-23 of a counter circuit 4 which continues a frequency division by an input of a switch 2 are connected to an AND circuit 12, a clock terminal of an FF circuit 7, and a clock terminal of an FF circuit 9, respectively, and a 1M signal 24 is connected to a gate 6, a shift register 17 for an indicator, a D terminal of the circuit 7, and an NAND gate 8. Also, 2M through 10M signal 25 are connected to the gate 6. In this state, when the circuit 4 is counted up and the 1M signal 24 rises to an H level, a display data of the shift register 17 is set up by one piece, a display of a display means 19 is turned on or off by one piece, it is informed that one minute of thermometry has elapsed, and a body temperature can be measured exactly based on the thermometric time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of non-professional use] The present invention relates to an electronic thermometer that holds and digitally displays the maximum temperature value during a measurement period.

[Conventional technology]

The temperature display method of conventional electronic thermometers was published in Japanese Patent Application Laid-Open No. 1983-1986.
Like No. 90, the temperature measurement status was displayed based on whether there was a rise in temperature within a certain period of time.

[Problem that the invention seeks to solve]

When measuring temperature with an electronic thermometer, the temperature under the armpit or under the tongue is not determined from the beginning, but it is gradually determined by placing the temperature sensor part of the electronic thermometer under the armpit or under the tongue and closing the armpit or under the tongue with a newspaper. The temperature of that part rises and reaches a certain temperature equilibrium only after a certain period of time has passed, and it cannot be assumed that temperature equilibrium has been reached just because the temperature has stopped rising within a certain period of time. There is a problem.

Therefore, the present invention aims to solve these problems.
The purpose of this is not to judge based on temperature rise;
To provide an electronic thermometer that can be judged based on the elapsed time when temperature is measured.

[Means for solving problems]

The electronic thermometer of the present invention is characterized in that the display is turned off, turned on, or blinks at specific time intervals or after a set time to display the elapsed temperature measurement time in numerical values.

Further, the electronic thermometer of the present invention is characterized in that the temperature measurement elapsed time is prompted by a ringing means at specific time intervals or after a set time.

Further, the electronic thermometer of the present invention is characterized in that the method of ringing the bell is changed between each specific time interval and after a set time, thereby ringing the bell at a specific time interval or after a set time has elapsed.

〔Example〕

FIG. 1 is a block diagram of an electronic thermometer in an embodiment of the present invention. In the figure, the output signal of the oscillation circuit 1 is input to the clock terminal of the counter circuit 4, the reset is canceled by the switch 2, and the counter output side is outputted to the converter 1.
5 and is input as a timing signal to the peak hold circuit 16. As a result, the temperature information 4 of the temperature sensor is converted into temperature DATA by the converter 15, and the temperature DATA is obtained.
D is input to the peak hold circuit 16 as A29.
The maximum temperature is stored in the ATA comparison seraglio. This bee (hold data value) is derived from the display means 19 via the LCD driver 18. Also, the time setting shift circuit 5 is a ring counter, and the input from the switch 3 causes the IT to
The output is shifted from OT and LOT to IT and can be set to a desired setting time.

Let's say you just set it to 10T. As a result, the 10T terminal 26 of the time setting shift circuit 5 becomes H level and is input to the selection gate 6, making the selection gate weighted for l() minutes active.

Next, by inputting the switch 2, the counter output 21 of the first half counter circuit 4, which continues to the minute μ3, is sent to the AND circuit 12.The counter output is sent to the clock terminal of the clip-flop, and the counter output n is sent to the clock terminal of the 7-lip flop 9.
The 1M signal 24 is connected to the selection gate 6, the indicator shift register 17, and the flip-flop 7.
The 2M to 10M signals 25 are respectively connected to the selection gate 6. A-1 Assume that the force counter circuit 4 counts up and the IM multiplication signal 4 rises to H level. (After 1 minute of temperature measurement) At this rise, one digit of indicator data in the indicator shift register 17 is set up, the output is passed through the LCD driver bay 8, one indicator of the display means 19 is turned on or off, and the temperature is measured. Derive a 1 minute elapsed display.

Also, in the previous period l l (signal) due to that rising signal, ii
The D input terminal of the IMe flip-flop 7 and the NAND circuit 8 become H level, and the color/return output 220
The NAND circuit 8 output is differentiated by the 7 rip 70 knob 7 and the NAND circuit 8 by an amount corresponding to time.
1. In Mjl's AND circuit J2,
III corresponding to the output time of the OR circuit 11 is chimed by the clock of the counter output 21, and the chime ψ11 means 13
It is derived by

When the IM signal of the counter circuit 4 rises, the indicator shift register 17 is shifted up to set two indicator data, and the output is sent to the display means 19 via the LCD driver 18. 2 indicators are turned on or off, and the 2-minute temperature reading is derived. Also, as mentioned in this special sale, during the period differentiated by the flip-flop 7 and the NAND circuit 8, the NAND 11. The signal is derived by the ringing means 13 via the AND 12. These operations are repeated up to the point previously set in the time setting shift circuit 5. Next, we will explain when the current set time 1 (1 minute) has been reached.
The M signal is activated by the rising edge of the M signal, and is input to the D input terminal of the flip-flop 9 and the NAND circuit 10 as a match signal n. As a result, the counter output is differentiated by the flip-flop 9 and the front 8 pinand circuit 0 by an amount corresponding to that time, and the output of the NAND circuit 10 is led out to the NAND circuit 11.

In the AND circuit 12, a bell is rung by the clock of the counter output 21 for a period corresponding to the output time of the OR circuit 11, and the bell is sounded by the ringing means 13.

Further, since the counter output η and the time of the counter output are different, it can be confirmed that the bell ringing every minute and the ringing after 1 minute (I7) are different.

FIG. 2 shows the display means of the electronic thermometer according to the embodiment of the present invention, and the lighting of the indicator 32 indicates that 3 minutes have elapsed since the temperature measurement special j has elapsed, and the current body temperature 31 is 36.5°C.
It is displayed that it is.

Also, this indicator may be blinking or off. Figure 3 shows the elapsed temperature measurement time using a numerical display device. Currently, the temperature measurement time has passed for 5 minutes, and the body temperature is 33.
It is displayed as 6.8°C. - [Effects of the Invention] As described above, according to the invention, since the temperature measurement time is considered as the base, it is possible to measure and understand body temperature much more accurately than the prediction method or the temperature constant force method. Furthermore, each person can easily predict his or her own equilibrium temperature based on the elapsed time of temperature measurement and the temperature rise gradient.

Also, since the temperature is measured every minute, your pulse can be measured at the same time as your temperature. In addition, since the elapsed temperature time can be seen at a glance and also reported by the ringing bell, it has the effect of being very convenient when measuring the amount of liquid.
