Description

TECHNICAL FIELD The present invention relates to an electronic thermometer which holds a maximum temperature value during measurement time and digitally displays it.

[Conventional technology]

A conventional method for displaying a temperature of an electronic clinical thermometer is disclosed in JP-A-54-659.
Like No. 0, the temperature measurement status was displayed depending on whether the temperature increased within a certain time.

[Problems to be solved by the invention]

In the temperature measurement by the electronic thermometer, the temperature under the armpit or sublingual is not completed from the beginning, and gradually from the moment when the armpit or sublingual is closed by sandwiching the temperature-sensitive sensor part of the electronic thermometer under the armpit or sublingual The temperature of that part rises and reaches a certain temperature equilibrium for the first time after a certain period of time elapses. It has a problem that it cannot be judged that it has been reached.

Therefore, the present invention solves such a problem,
The purpose is not judgment by temperature rise,
There is a place to provide an electronic thermometer that can be judged by the elapsed time during temperature measurement.

[Means for solving problems]

The electronic thermometer of the present invention includes a measuring circuit for measuring elapsed time of temperature measurement, a first display member for displaying the elapsed time by the measuring circuit, and a second display for displaying a maximum temperature value during the elapsed time. A member, a time setting circuit for setting a temperature measurement measurement end time, a first ringing signal output circuit for outputting a first ringing signal every time a predetermined time of the elapsed time elapses, and the time after the measurement end time elapses A second ringing signal output circuit for outputting a second ringing signal whose operation time is different from that of the first ringing signal, and a first ringing sound and a second ringing sound, respectively. A ringing means for outputting a ringing sound based on the signal operation time is provided.

〔Example〕

FIG. 1 is a block diagram of an electronic thermometer according to an embodiment of the present invention. In the figure, the output signal of the oscillator circuit 1 is input to the clock terminal of the counter circuit 4, the reset is released by the switch 2, the counter output 20 is output, and the converter 15
And as a timing signal of the peak hold circuit 16. As a result, the temperature information 28 of the temperature sensitive sensor 14 is temperature-DATA converted by the converter 15 and input to the peak hold circuit 16 as the temperature DATA 29, and the maximum temperature is always stored after the DATA comparison. This peak hold data
30 is led out from the display means 19 via the LCD driver 18. Further, the time setting shift circuit 5 is a ring counter, and by the input of the switch 3, 1T to 10T, 10T to 1T.
The output is shifted to and can be set to the desired set time.

Suppose you have 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 to activate the selection gate weighted for 10 minutes.

Next, the counter output 21 of the previous period counter circuit 4 which continues frequency division by the input of the switch 2 is to the AND circuit 12, the counter output 22 is to the clock terminal of the flip-flop, the counter output 23 is to the clock terminal of the flip-flop 9, and the 1M signal 24 is The selection gate 6, the shift register 17 for an indicator, the D input terminal of the flip-flop 7 and the NAND gate 8 are respectively connected, and the 2M to 10M signals 25 are respectively connected to the selection gate 6. Now, assume that the counter circuit 4 counts up and the 1M signal 24 rises to the H level.
(After 1 minute of temperature measurement) This rising causes the indicator data of the indicator shift register 17 to be set up by one, and the output thereof is set to the LCD driver 18
After that, one indicator of the display means 19 is turned on or off, and the progress of temperature measurement for 1 minute is displayed.

In addition, the D signal input terminal of the flip-flop 7 and the NAND circuit 8 become H level by the rising signal of the 1M signal 24 in the previous period, and the flip-flop 7 and the NAND circuit 8 are differentiated by the time corresponding to the time of the counter output 22. The output of the NAND circuit 8 is led to the NAND circuit 11.
In the AND circuit 12, during the output time of the NOR circuit 11, the counter output 21 is ringed and is output by the ringing means 13.

Again, when the 1M signal 24 of the counter circuit 4 rises, the shift register 17 for the indicator is shifted up to set two pieces of indicator data, and the output is passed through the LCD driver 18 and the display means 19. 2 indicators are turned on or off to derive a temperature measurement 2 minute progress display. Further, at this time, as described above, the ringing means 13 outputs the signal through the NAND 11 and AND 12 for a period differentiated by the flip-flop 7 and the NAND circuit 8. These are repeated up to the position previously set in the time setting shift circuit 5. Next, the time when the current set time reaches 10 minutes will be described. The 10-minute weighted AND circuit of the select gate 6 is activated by the rise of the 10M signal 25 of the counter circuit 4, and the H level is sent to the D input terminal of the flip-flop 9 and the NAND circuit 10 as a coincidence signal 27. Is entered. As a result, the flip-flop 9 and the NAND circuit 10 are differentiated by the time corresponding to the counter output 23, and the output of the NAND circuit 10 is led to the NAND circuit 11. In the AND circuit 12, the counter output 21 is ringed during the output time of the OR circuit 11 and is output by the ringing means 13.

Further, since the counter output 22 and the counter output 23 are different in time, it is possible to confirm different ringing for the ringing every 1 minute and the ringing after 10 minutes.

FIG. 2 shows the display means of the electronic thermometer in the embodiment of the present invention, showing that the temperature measuring time has passed 3 minutes by turning on the indicator 32, and indicates that the current body temperature 31 is 36.5 ° C. .

Further, this indicator may be blinking or off.

FIG. 3 shows the elapsed time of temperature measurement by the numerical value display 34. Currently, the temperature measurement time has passed 5 minutes and the body temperature 33 is 36.
It indicates that it is 8 ° C.

〔The invention's effect〕

The electronic thermometer of the present invention includes a first display member for displaying elapsed time, a first ringing signal output circuit for outputting a first ringing signal every time a predetermined time of the elapsed time elapses, and a measurement end time. A second ringing signal output circuit for outputting a second ringing signal different from the first ringing signal after a lapse of time, and ringing means for receiving and ringing the first and second ringing signals. As a result, not only can the measurement elapsed time be reliably known visually and aurally, but also the measurement end time can be known without being mistaken for a ringing during the elapsed time.
