Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application This invention relates to a toilet-mounted electronic thermometer that is installed in a toilet bowl and measures body temperature by detecting the temperature of urine released from the body.

(b) Conventional technology Conventional thermometers include mercury thermometers and electronic thermometers (
Are known. Although these thermometers have different measurement principles, they all take measurements by placing or inserting the temperature measuring part under the tongue, armpit, or rectum.

(c) Problems to be solved by the invention As mentioned above, conventional thermometers touch the temperature measurement part under the tongue, under the armpits, etc., in other words, on the surface of the living body, and detect the equilibrium temperature between the surface of the thermometer and the surface of the living body. Because it is a thermometer, it can only measure the temperature on the surface of the living body, and it measures the equilibrium temperature.
It takes about 10 minutes. In addition, for areas such as under the tongue or under the armpits, the person taking the thermometer must place the thermometer in a predetermined position to take the measurement. Measurement is troublesome because it requires steps such as reapplying the thermometer, and it is necessary to hold the thermometer at rest while taking the temperature, which causes stress and sometimes pain during the measurement. .

In view of the above, it is an object of the present invention to provide an electronic thermometer that allows a person to measure body temperature naturally without feeling much tension or pain while measuring body temperature, and that can accurately measure body temperature without contacting the living body. It is an object.

(d) Means and Effects for Solving Problems The electronic thermometer installed in a toilet bowl of the present invention includes a temperature sensor disposed in a portion of the toilet bowl from which urine from the body is discharged, and a means for setting a body temperature measurement mode. and a display means for displaying the temperature detected by the temperature sensor as the body temperature when the body temperature measurement mode is set.

With this toilet-mounted electronic thermometer, when a person to be measured urinates in the toilet bowl, the urine temperature of the urine expelled from the body is detected by a temperature sensor installed in the toilet bowl, and the urine temperature is usually measured at the ambient temperature. , so the detection temperature will spike when urine is detected, and this spike will set the temperature measurement mode,
Under the setting of this body temperature measurement mode, the temperature detected by the temperature sensor is displayed on the display means as body temperature. This toilet-mounted electronic thermometer measures the urine temperature and displays the temperature as approximately the same as the body temperature, so the person taking the measurement does not feel the tension of measuring their own body temperature, and can measure the body temperature quickly. Can be done.

(E) Examples The present invention will be explained in more detail with reference to Examples below.

FIGS. 3(a) to 6 show the case where the present invention is applied to a sit-down toilet bowl.

The electronic thermometer of this embodiment includes a temperature sensor section 1 and a main body section 2.
The main body part 2 is installed on the left side of the toilet bowl 11, and the temperature sensor part l is arranged so as to be exposed inside the front slope 11a of the toilet bowl 11 [Fig. 3 (a) ,
See Figure 3(b) and Figure 4].

The main body 2 includes a display 5 and a printer 6 as well. In addition, the temperature sensor part 1 is connected to the slope part 11 of the toilet bowl 11, as shown in FIG. 5, which is an enlarged view of part A in FIG.
The insulation material ib and the metal thin plate I are installed by pasting etc.
C and a thermistor LAS lead wire 1d as a heat-sensitive element provided on the inner surface of the thin metal plate IC in the hollow space formed between them. A temperature signal detected by the thermistor 1a is input to the main body 2 via a lead wire 1d.

The reason why the sensor part 1 is provided with the heat insulating material 1b is to prevent the heat absorbed from urine from dissipating backward, and also to prevent the heat absorbed from the urine from dissipating backward.
The purpose of covering the thermistor 1a with the thin metal IC is to improve the absorption of temperature from urine and to protect the thermistor 1a.

The sensor section 1 shown in FIG. 5 is of a type that is attached to the surface of the slope 11a of the toilet bowl 11, but as shown in FIG. 11b, a heat insulating material 1b, a metal thin film 1cs, a thermistor 1a and a lead wire 1d provided in the hollow space made up of these.
The sensor part 1 consisting of the thermistor 1 is buried.
The metal thin plate IC provided on the back surface of the toilet bowl 11 may be made to protrude toward the inner surface of the toilet bowl 11, and the urine temperature may be detected by the urine flowing through this portion.

FIG. 2 is a schematic block diagram of the electronic circuit section of the electronic thermometer of this embodiment, and the temperature signal detected by the sensor section 1 is
The temperature signal is taken into the control part 3 of the main body part 2, and is stored in the memory 4 at a predetermined sampling period under the control of the control part 3. can now be measured. Further, a display 5 and a printer 6 are connected to the control unit 3, and the display 5 selectively displays room temperature and body temperature.
The printer 6 is capable of printing out the measured room temperature or body temperature at the required timing.Normally, the control unit 3 detects the temperature signal from the sensor unit 1, and if there is no sudden temperature change, The room temperature is measured and displayed on the display 5. When the person taking the test urinates, the sensor part l
detects the temperature of this urine, and the detected temperature rises rapidly,
The control unit 3 detects this sudden rise and determines that the body temperature is in the body temperature measurement mode, and the display 5 displays the body temperature in text and the detected temperature as the body temperature.

The operation of this embodiment of the electronic thermometer will be explained with reference to the flowchart shown in FIG.

When the power is turned on and the device is in a normal measurement state, first, in step STI, it is determined whether the sampling time has arrived. This sampling time is normally such that the signal from the sensor section 1 is taken every second. When the sampling time arrives, the sensor unit 1 detects the temperature T at that time, and the control unit 3 stores the temperature T! in the memory 4. (step 572). Next, it is determined whether the flag F is 0 (step 5T3). This flag F is a flag that specifies the measurement mode, and when it is O, it indicates the room temperature measurement mode, and when it is 1, it indicates the body temperature measurement mode.

At the beginning of the measurement, F=O, and this judgment is NO.
The process moves to step ST4. Then, the difference value (T!) between the previous measured value 'rt-t and the current temperature TI.
T! -1) and determine whether this temperature increase value is greater than a predetermined value (step 5T4)
, when only the room temperature is being measured, there is no sudden temperature change, so 'ri-T'i-+ will not exceed the predetermined value,
Therefore, the determination in step ST4 is NO, and in this case, the characters "room temperature" are displayed on the display 5 in step ST5, and the temperature detected by the sensor unit 1 at that time is digitally displayed (step 5T8). Next, in step ST9, it is determined whether or not time has expired, but since the timer is not activated in this mode, the determination is No, and the process returns to step STI. Thereafter, the above process is repeated every time a sampling time arrives.

Next, when the person taking the test urinates, the urine passes over the metal thin IC of the sensor section 1, and the temperature at this time is detected by the thermistor 1 and inputted to the control section 3 (step 5T2).
Flag F is O until then, so step ST3
The judgment is YES, and then T! It is determined whether T=-+>K (step 5T4), but this determination becomes YES due to a sudden rise in temperature due to urination. Then step ST6
, start the timer, and set flag F to 1.
(Step 5T7) Then, the text "body temperature" is displayed on the display 5, and the detected temperature at that time is digitally displayed. An example of the display at this time is shown in FIG.

Next, in step ST9, it is determined whether or not time is up. Here, the timer is set to 30 seconds, and the timer will expire 30 seconds after the temperature rises, that is, the patient starts urinating.

Therefore, until then, the determination in step ST9 is NO, and the process returns to step STl. Thereafter, the temperature T is detected at every sampling time, but in step ST3 the flag F=
1, the determination is No, and step ST8, ST
6 and moves to step ST7. and,"
Continues to display the characters ``body temperature'' and the digital display of the detected temperature.In other words, the body temperature measurement mode is maintained for 30 seconds.The urination time varies depending on the person, but if it is about 10 to 30 seconds, at least the metal thin plate IC will be displayed during this time. The thermistor 1a measures the urine temperature via the sensor, and the display 5 can display the body temperature measurement relatively quickly.

When the timer times up, the determination in step ST9 becomes YES, and flag F is set to O (step 5T10).
), the room temperature measurement mode is entered, and the process returns to step STI.

FIGS. 7(a) to 9 show examples in which the electronic thermometer of the present invention is applied to an upright toilet bowl.

In this embodiment, the main body part 2 is arranged on the ceiling part 21a of the toilet bowl 21, and the sensor part 1 is provided at the lower part of the side vertical wall part 21b of the toilet bowl 21. As shown in Fig. 8, urine hits the sensor section 1 which is composed of a heat insulating material 1b and a thermistor 1a provided in a hollow part of a thin metal plate 1c, and the temperature of the urine is detected by the thermistor 1a from the thin metal plate 1c, and a temperature signal is generated. is input to the controller 3,
Afterwards, your body temperature will be measured in the same way as above.

Furthermore, in the upright toilet bowl in this case, the sensor section 1 may be provided on the vertical wall section 21b as shown in FIG. 8, but as shown in FIG. A sensor section 1 may also be provided. Body temperature measurement at the upright toilet is also performed based on the flow diagram shown in FIG.

In the above embodiment, when measuring body temperature, when the person taking the urine urinates, the sensor unit detects a sudden rise in temperature due to urine and enters body temperature measurement mode, and displays the body temperature. Normally, the room temperature is displayed using a button, and when the mode is set to body temperature using the switch button, the body temperature is displayed, and if the person taking the urine urinates, the temperature is detected and the body temperature is displayed. good.

(F) Effects of the Invention According to this invention, a temperature sensor such as a thermistor is installed in the toilet bowl, so compared to conventional thermometers, etc.
There is no need to increase the strength of the thermistor mounting part, the temperature measurement part can be made smaller, and the heat capacity is also smaller, resulting in better thermal response.Furthermore, equilibrium temperature can be obtained in a few seconds, so measurements can be carried out in a short time. measurement time can be shortened. Furthermore, since body temperature can be measured using only the natural action of urinating, measurement errors due to external factors (such as how it is applied and how it is held) can be reduced, which has the advantage of making it possible to measure body temperature more accurately. . Furthermore, measurements can be performed without causing a sense of complication to the measurer compared to conventional methods.
