DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic clinical thermometer capable of measuring the temperature of different parts of a human body.

[0002]

2. Description of the Related Art In recent years, electronic thermometers have been increasingly provided with a temperature measuring function and are required to be easy for a user to handle.

At present, electronic thermometers widely used include:
It can be divided into two types, a prediction formula and an actual measurement formula.
The actual measurement formula is further subdivided into a time formula and a stability detection formula depending on how to determine the end of the temperature detection. The time-type electronic thermometer measures a predetermined time, for example, 3 minutes and 5 minutes, and notifies the end of the temperature detection by a buzzer or the like when the time reaches the predetermined time. In addition, the electronic thermometer of the stability detection type reports, for example, by a buzzer or the like when the rise of the temperature value for a predetermined time becomes equal to or lower than a predetermined temperature rise rate.

[0004] On the other hand, human body parts to which such an electronic thermometer is applied generally include the armpits and the inside of the mouth.
Each of these sites has a different appropriate temperature measurement time.
For example, it is said that the temperature measurement time is 5 minutes for the armpit and 3 minutes for the sublingual mouth.

This is because, as shown in FIG. 10, the temperature rise curve of the temperature sensing part of the electronic thermometer differs between the armpit and the mouth.

For example, in the mouth, when the temperature sensing part of the electronic thermometer is applied under the tongue in the mouth, it is immediately shut off from the outside air, the temperature of the temperature sensing part rises rapidly, and the equilibrium state is reached in about three minutes (from the body temperature). (0.2 ° C-0.3 ° C lower practical temperature). On the other hand, in the case of the armpit, when the temperature sensing part is inserted in the armpit and the armpit is closed, the heat dissipation to the outside air subsides, and from here the internal temperature measurement through the skin starts, but through the skin Because the blood circulation in the body, heat supply is performed slowly, and the temperature rise curve becomes gentler than at the time of oral temperature measurement, and it takes about 5 minutes,
An equilibrium state is reached which is about 0.2-0.3 ° C lower than the sublingual temperature in the mouth. In addition, the stability detection type detects the equilibrium state and notifies the end of the temperature detection.

In addition, the temperature of the temperature sensing portion will gradually rise in the future, approaching the body temperature, and the accuracy of the temperature measurement will be increased. For this purpose, it takes about 5 minutes under the tongue in the mouth and about 10 minutes under the armpit. Need to be applied.

Normally, an electronic thermometer has the above-mentioned two temperature rise curves, so that a buzzer sounds as time elapses, such as 1 minute, 2 minutes, 3 minutes, and 5 minutes. Accordingly, the user can confirm the temperature detection value.

However, in this case, the user must count the number of times of the buzzer sound. For example, if the user counts the number incorrectly or forgets that the take-out time differs depending on the temperature measurement site, the user may take a proper time. The thermometer may not be obtained accurately because the electronic thermometer is removed earlier than before. Furthermore, the spread of predictive electronic thermometers has widened the perception that buzzer notification is a signal to end the temperature measurement.As a result, even when using the actual measurement type electronic thermometer, the buzzer sound was mistaken for the signal indicating the end of the temperature measurement rather than the notification of elapsed time. Therefore, there is a problem that the electronic thermometer is taken out before the appropriate time, and the measured temperature value is lower than the actual value. In addition, when the temperature measurement function of the electronic thermometer increases, the user needs to reread the instruction manual and the like when using the electronic thermometer and check the operation procedure.

[0010]

As described above, in the above-mentioned conventional electronic thermometer, since the means for informing the end point of the temperature measurement to the different temperature measurement parts is only a buzzer sound with the passage of time, the user can use the electronic thermometer. There was a problem that it was difficult to handle and there was a case where the temperature measurement was mistaken.

The present invention has been made to solve such a problem, and an object of the present invention is to provide an electronic thermometer which is easy for a user to handle and which does not have a temperature measurement error.

[0012]

In order to achieve the above object, an electronic thermometer according to a first aspect of the present invention measures the maximum temperature of the temperature measuring portion based on a signal from a temperature sensing portion abutted on the temperature measuring portion of the human body. In an electronic thermometer for measuring and displaying the temperature value, a display means for displaying a plurality of temperature measurement modes corresponding to different temperature measurement parts of the human body, and one of the temperature measurement mode displays of the display means for selecting and operating one of the temperature measurement mode displays. , A transmission circuit section for transmitting a reference clock signal of a predetermined frequency only when selected by the switch, a clock counter for counting the reference clock signal from the transmission circuit section, and time information of the clock counter.

Means for setting a time interval, a time measurement means for starting time measurement when the temperature detection mode is selected by the selection means, and an end of temperature measurement when the time measured by the time measurement means reaches the temperature measurement end time. Notification means.

According to a second aspect of the present invention, there is provided an electronic clinical thermometer which measures a maximum temperature of a temperature sensing part based on a signal from a temperature sensing part which is in contact with the temperature sensing part of a human body and displays the temperature value. Display means for displaying a plurality of temperature measurement modes corresponding to different temperature measurement parts, a selection means for selecting one of the temperature detection mode displays on the display means in accordance with the number of selection operations, and a selection means selected by the selection means. Means for setting a temperature detection end time according to the temperature detection mode, when the temperature detection mode is selected by the selection means, a time counting means for starting time measurement, and a time measured by the time measurement means corresponds to the temperature detection end time. And a notifying means for notifying the end of the temperature detection when the temperature has reached.

[0014]

According to the first aspect of the invention, the temperature detection mode is selected according to the time when the switch is selected and the temperature detection mode is displayed on the display means. Then, the temperature detection end time is set according to the selected temperature detection mode, the time measurement is started by the timer, and when the temperature detection end time is reached, the notification means notifies the end of the temperature detection.

In the second invention, the temperature detection mode is selected according to the number of times of selection operation of the selection means, and the temperature detection mode is displayed on the display means. Then, the temperature detection end time is set according to the selected temperature detection mode, the time measurement is started by the timer, and when the temperature detection end time is reached, the notification means notifies the end of the temperature detection.

Therefore, when measuring the temperature, the user can select the temperature measurement mode while watching the temperature measurement mode display corresponding to the temperature measurement site on the display means, and there is no need to read an instruction manual or the like. In addition, the temperature detection end time is set according to each temperature detection mode, and when the time comes, the end of the temperature detection is notified, so that the user can take out the electronic thermometer from the temperature detection site at this point to know the temperature at that time almost exactly. Can be.

That is, the user can easily handle the electronic thermometer and can eliminate a temperature measurement error.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an external view of an electronic thermometer according to an embodiment of the present invention, and FIG. 2 is a block diagram showing the configuration of the electronic thermometer of FIG.

As shown in FIG. 1, a main body 1 of the electronic thermometer is provided with a temperature sensing section 2 at a tip thereof. The temperature sensing section 2 is applied to a temperature measurement site (in the mouth or under the armpit) of a human body to sense the temperature of the site and convert the temperature into an electric signal (resistance value, etc.). And a protective cap for covering the surface of the heat-sensitive element. At the center of the surface of the main body 1, there is provided a display unit 3 for displaying a digital value of the temperature value, a display indicating a sublingual temperature measurement mode, a side temperature measurement mode, and the like. Further, a power switch 4 is provided on the surface of the main body 1 for instructing an internal electronic circuit to start and stop an operation and for switching a temperature detection mode according to a temperature detection site.

Next, a circuit configuration inside the electronic thermometer will be described with reference to FIG.

In FIG. 1, reference numeral 5 denotes a power supply unit such as a lithium battery, which is detachably mounted in the main body 1. Reference numeral 6 denotes a temperature calculation unit, which performs A / D conversion of an electric signal (temperature detection signal) from the temperature sensing unit 2 to perform temperature conversion. Reference numeral 7 denotes a transmission circuit unit, which is turned on when the power switch 4 is turned on.
And transmits a reference clock signal having a predetermined frequency. Reference numeral 8 denotes a clock counter, and the transmission circuit unit 7
The reference clock signal from the counter is counted. Reference numeral 9 denotes a control circuit unit, which starts operation by receiving power supply from the power supply unit 5 when the power switch 4 is turned on, and performs temperature detection control based on time information of the clock counter 8. 10 is a timing section,
Time measurement is started according to an instruction from the control circuit unit 9. Reference numeral 11 denotes a notification unit such as a piezoelectric buzzer, which emits a buzzer sound according to an instruction from the control circuit unit 9.

Next, the flowcharts of FIGS.
The operation of the electronic thermometer will be described with reference to the display example of FIG.

In the case of this electronic thermometer, as shown in FIG. 3, when the power switch 4 is turned on within, for example, one second from a state in which all functions are stopped, the power supply unit 5 sends the signal to the transmission circuit unit 7 during this on time. When power is supplied, a reference clock signal is transmitted from the transmission circuit unit 7 and the reference clock signal is counted by the clock counter 8. The time information counted by the clock counter 8 is input to the control circuit unit 9.

When the power switch 4 is turned on, power is supplied from the power supply section 5 to the control circuit section 9, and the control circuit section 9 causes the temperature sensing section 2 and the temperature calculation section to start the temperature detection operation. 6 and initializes each part according to the length of the input time information (with initialization) (step 301). The initialization operation at this time is as follows:
This is a reset operation of the clock counter 8, the timer 10, and the like.

After the initialization, the control circuit section 9 confirms whether or not the power switch 4 is kept on (step S1).
302). In this case, the time when the power switch 4 is turned on is 1 second or less, and the power switch 4 is already in the on state.
The temperature detection end time is set to two times of 5 minutes and 10 minutes. Then, the control circuit unit 9 checks the presence or absence of the temperature detection mode sign on the display unit 3 and if no temperature detection mode sign is displayed,
The display unit 3 is instructed to display the armpit temperature detection mode sign. As a result, as shown in FIG. 5 (a), the bar display A (armpit temperature detection mode sign) is lit on the lower part where the temperature value, for example, “36” is displayed on the display unit 3 (step). 303).

On the other hand, in step 302, when the ON state continues for one second (step 304), the temperature detection end time is switched to 3 minutes and set. In this case, the control circuit unit 9 substitutes 1 for Flag1 (sets a flag), and as a sublingual sublingual temperature detection mode sign, as shown in FIG. The bar display B is turned on (step 305). Such a temperature-measuring mode sign is not limited to the bar displays A and B in FIG. 7A, but is displayed as “WAKI”, “KUCHI” or the like as shown in FIG. Become. Further, as shown in FIG. 3C, for example, "1" may be displayed on the temperature display section at the moment when the power switch 4 is turned on, and "2" may be digitally displayed after one second or more.

After that, the control circuit 9 instructs the timer 10 to measure time, and the timer 10 starts measuring time (step 306).

Then, the control circuit section 9 fetches the time information from the timer section 10 sequentially, and based on this time information, sends the temperature sensing section 2 to the temperature calculating section 6 at predetermined time intervals, for example, every one second. (Step 307).

In response to this instruction, the temperature calculation section 6 performs a temperature measurement operation (step 308), and the measurement result is displayed on the display section 3.
Is displayed each time (step 309). Further, the control circuit unit 9 confirms Flag1 for each sampling (step
310) Then, the measurement time value in the temperature detection mode at that time is confirmed by the timer unit 10. For example, if 1 is substituted for Flag1, the temperature measurement mode is the sublingual temperature measurement mode, and the temperature measurement end time is 3 minutes.
It is confirmed whether or not the time measurement is 3 minutes (step 311), and when this measurement time reaches 3 minutes, the notification unit 11 is instructed to notify. Then, the notification unit 11 emits a buzzer sound in response to the instruction (step 312).

On the other hand, if the flag is not set in Flag 1 (step 310), the temperature measurement mode is the armpit temperature measurement mode, and the temperature measurement end time is two minutes and five minutes. Then (step 313), the notification unit 1
1 emits a buzzer sound (step 312 above) to urge the user to confirm the first temperature measurement. The user takes out the electronic thermometer from the armpit by this buzzer sound, and looks at the temperature display on the display unit 3 and finds that the practical temperature (approximately 0.2 ° C.-
The body temperature can be known almost accurately within the range of 0.3 ° C lower).

When the temperature measurement is completed, the user presses the power switch 4 twice in succession, so that the control circuit 9
After the operation, the power is turned off (step 314). However, when it is desired to more precisely measure the body temperature or when it is considered that there is slight fever, the electronic thermometer is applied to the armpit again. Then, the sampling operation and the temperature display are repeated (steps 315 to 319), and the timer 1
The time measurement of 0 also proceeds, and when this time reaches 10 minutes (step 320), a buzzer sound is emitted again (step 320).
321) At this time, if the user checks the display unit 3, the user can know the accurate body temperature.

Further, unless the power switch 4 is continuously pressed twice (step 322), the measurement is continued, and when the sample timing comes (step 323), the temperature is measured (step 324), and the display unit 3 is started. Is displayed (step 325).

As described above, according to the electronic thermometer of the present embodiment, the internal circuit is switched to two temperature measurement modes, the armpit temperature detection mode and the sublingual temperature detection mode, according to the time when the power switch 4 is pressed. One of the switched temperature detection mode signs, for example, the armpit temperature detection mode sign A is displayed on the display unit 3.
Is displayed on the display, the user can understand the setting state of the temperature measurement site by looking at the display contents, and can use the electronic thermometer without looking at the instruction manual.

If a temperature detection mode indicating each temperature detection part is set by the power switch 4, the temperature detection time is changed according to the part, and when the timer part 10 reaches its end time, a buzzer sounds from the notification part 11. Therefore, if the user takes out the electronic thermometer from each part at this time, the user can know the body temperature within the practical temperature range regardless of the part. Further, when the user wants to accurately measure the internal temperature or when it is considered that there is a slight fever, the user waits until the next buzzer sound is emitted, and can know the internal temperature almost exactly by looking at the display unit 3. it can.

In this embodiment, the switching time of the temperature detection mode is set to 1 second. However, the switching time is not limited, and may be set within a range that does not give a user a sense of discomfort.

In this embodiment, two buzzer notification times are set in the armpit temperature measurement mode, but may be set to two minutes and three minutes in the sublingual temperature measurement mode. Alternatively, only one temperature setting mode may be set.

Further, in this embodiment, display examples of the temperature detection mode are shown in FIGS. 5 (a) to 5 (c). In addition, for example, a standby display (preparation OK display of each instrument) is used. When a standby display such as “32.0 ° C.” or “−−−” is lit, the armpit temperature detection mode sign may be used, and the standby display may be blinked to set the sublingual mouth tongue temperature detection mode sign. Alternatively, only the “° C” mark may be lit or blinked to identify the two temperature detection modes,
The identification of the temperature detection mode can be variously modified.

Next, another embodiment of the present invention will be described with reference to FIGS.

FIG. 6 is a block diagram showing the internal configuration of the electronic thermometer of this embodiment.

The same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof will be omitted.

In the figure, reference numeral 61 denotes a power switch, which supplies power to the internal circuit of the electronic thermometer when it is turned on and stops power when it is turned off, and switches between the armpit temperature measurement mode and the sublingual temperature measurement mode for each knock. A control signal for selecting two temperature detection modes is transmitted. Reference numeral 62 denotes a control circuit which sets a temperature detection mode based on a selection control signal from the power switch 61 and controls the operation of peripheral circuits according to the set temperature detection mode.

Next, the operation of the electronic thermometer will be described with reference to the flowchart of FIG. 7 and a display example of FIG.

In the case of this electronic thermometer, when the power switch 61 is knocked once from a state where all functions are stopped, power is supplied from the power supply unit 5 to the control circuit unit 62, and the control circuit unit 62 performs a temperature measurement operation. , The temperature sensing section 2 and the temperature calculating section 6 are instructed to start, and the display section 3, the temperature calculating section 6 and the time measuring section 10 are initialized (initialized) (step 701).

The initialization operation at this time is as follows.
For example, there are a standby display operation of the display unit 3, a reset operation of the temperature calculation unit 6 and the timer unit 10, and an operation of setting the temperature detection end time to two times of 5 minutes and 10 minutes.

If the power switch 61 is not knocked again (step 702), the control circuit 62
Check Flag1, and if Flag1 is not 1 (step 703), substitute 1 for Flag1 (step 704).
), The display unit 3 is instructed to light the armpit temperature detection mode sign. Thereby, as shown in FIG.
, The armpit temperature detection mode sign A is lit (step
705).

The control circuit 62 instructs the timer 10 to measure time, and the timer 10 starts measuring time. Then, the control circuit unit 62 fetches the time information from the timer unit 10 sequentially, and based on the time information, sends the temperature calculation unit 6 from the temperature sensing unit 2 at predetermined time intervals, for example, every 1 second. An instruction is issued to sample the temperature detection signal (step 706). In response to this instruction, the temperature calculation unit 6 measures the temperature (step 707), and the measurement result is displayed on the display unit 3 each time (step 708).

While the temperature measurement operation and the display operation (temperature measurement operation) are repeated, if the timer 10 measures 5 minutes (step 709), the control circuit 62 notifies the notification unit 1.
1 and instruct the notification unit 11 to emit a first buzzer sound (step 710).

Thus, the user can know the body temperature (practical temperature) at that time by seeing the temperature value displayed on the display unit 3 of the electronic thermometer.

In this embodiment, the buzzer notification time in the armpit temperature detection mode is set to two times of 5 minutes and 10 minutes, so that even after the first buzzer sound is emitted, the temperature measurement operation, display operation, etc. Is repeated. Here, if the power switch 61 is knocked twice consecutively and the power is turned off (step 711), or if the power switch 61 is knocked once (step 712), the temperature detection operation in the armpit temperature detection mode ends. I do.

For example, when the user wants to more precisely measure the temperature inside the body or when it is considered that there is slight fever, unless the power switch 61 is knocked, the temperature measurement operation in the underarm temperature detection mode is repeated (steps 713 to 713). 715). Then, when the timer 10 measures 10 minutes (step 716), the control circuit 62 instructs the notifying unit 11 to notify, and the notifying unit 11 emits a second buzzer sound according to the instruction (step 717). At this point, the user can almost accurately know the body temperature at that time by looking at the display of the temperature value shown on the display unit 3 of the electronic thermometer.

Here, similarly to the above, when the power is turned off (step 718) or the power switch 61 is knocked once (step 719), the temperature detection operation in the armpit temperature detection mode is terminated. If there is no operation, the temperature measurement operation is further repeated (steps 720 to 722),
The control circuit 62 waits for the power to be turned off (step 723).

On the other hand, if the power switch 61 is knocked once after initialization or during the temperature detection operation (steps 702, 712, and 719), a selection control signal is sent from the power switch 61 to the control circuit unit 62. You.
Based on the selection control signal, the control circuit unit 62 instructs the temperature calculation unit 6 and the display unit 3 to switch the temperature measurement operation from the armpit temperature measurement mode to the sublingual temperature measurement mode. As a result, FIG. As shown, the sublingual sublingual temperature measurement mode sign B is displayed on the display unit 3 (step 724).

From here, the temperature measurement operation in the sublingual sublingual temperature measurement mode is started, and the control circuit 62 sets the temperature measurement end time to two minutes and three minutes.

Then, the temperature measurement operation is repeated (step
725 to 727), when the timer 10 measures 3 minutes (step 728), a first buzzer sound is emitted (step 729). At this time, the user can know the practical temperature under the tongue in the mouth by checking the display unit 3.

When the power is turned off, if the power switch 61 is knocked once, all functions of the electronic thermometer are stopped (step 730).

If the power switch 61 is not knocked,
Further, the temperature detection operation is continued, and sample timing (step 731), temperature measurement (step 732), temperature display (step 733), and the like are performed.

When the timer 10 measures 5 minutes (step 734), a second buzzer sound is emitted (step 735). At this point, the user can almost accurately know the body temperature under the tongue in the mouth by checking the temperature value on the display unit 3.

As described above, if the power is not turned off (step 736), the temperature measurement operation is repeated (steps 737 to 739), and the control circuit 62 waits for the power to be turned off (step 740). .

As described above, according to the electronic clinical thermometer of the present embodiment, three modes of the armpit temperature detection mode, the sublingual temperature measurement mode, and the power-off mode are switched according to the number of times the power switch 61 is knocked. Since the mode state is displayed on the display unit 3, the user looks at the display contents and
The user can understand the setting state of the temperature measurement site and the on / off state of the power supply, and can use the electronic thermometer without reading the instruction manual.

Further, the temperature detection end time is set in accordance with each temperature detection mode, and when the time comes, the end of the temperature detection is notified. Therefore, at this time, the user takes out the electronic thermometer from the temperature detection site and looks at the value of the temperature measurement. The body temperature at that time can be known almost exactly, and there is no occurrence of a temperature measurement error such that the electronic thermometer is taken out earlier than the appropriate time of the temperature measurement site.

Further, as compared with the first embodiment,
Since the transmission circuit unit 7 and the clock counter 8 are not required, an easy-to-handle and accurate electronic thermometer can be obtained with a small number of configurations.

In this embodiment, when the power switch 61 is knocked once after initialization or during the temperature detection operation, the temperature detection mode can be switched. However, for example, by performing the mode switching operation before the temperature detection, the power supply mode can be switched. The power can be turned off by knocking the switch 61 once. Further, the buzzer notification time is not limited to 3 minutes, 5 minutes, and 10 minutes, and various times can be set.

[0064]

As described above, according to the electronic thermometer of the present invention, the temperature measurement mode can be selected in accordance with the time or the number of times the selection means is selected and operated, and the temperature measurement mode display is displayed on the display unit. Then, the user can see the display and measure the temperature, and the electronic thermometer can be easily handled. In addition, the temperature detection end time is set according to each temperature detection mode, and when the time comes, the end of the temperature detection is notified, so that the user can take out the electronic thermometer from the temperature detection site at this point and look at the measured value to see the temperature at that time. Can be known almost exactly, and there is no occurrence of a temperature detection error such as erroneous removal timing.
