CONSTITUTION:The titled thermometer is constituted so as to include a temp. sensor 2, an A/D converter 6, an operation processing part (CPU)7, memory 8, a decoder 9 and an analogue temp. display part 3 while the analogue temp. display part 3 is constituted by arranging a large number of bar shaped LCD elements directed to a temp. change direction at right angles and the lighting and display color of each LCD element are respectively controlled by a decoder. A switch 5 is turned ON and the temp. sensor 2 of an electronic clinical theremometer 1 is contacted with the predetermined part of the human body to measure temp. T. That is, when 35<=T<=37 deg.C, the LCD element corresponding to the measuring temp. T or less is indicated to green in the LCD analogue temp. display part 3. When T<38 deg.C, the LCD element corresponding to the temp. between 37 deg.C and the measuring temp. is indicated to an orange color and, when T>=38 deg.C, the LCD element between 38 deg.C and the measuring temp. T is indicated to a red color.

Description

[Detailed description of the invention] <Technical field of invention> The present invention relates to an electronic thermometer.

<Prior art and problems> Conventional electronic thermometers display the measured temperature in digital numbers, or by changing the length of the illuminated part of the elongated temperature display section and displaying it in analog form in one color. .

Therefore, this type of display has the disadvantage that it cannot be read at a glance when an approximate temperature is desired.

<Object of the Invention> An object of the present invention is to provide an electronic thermometer that is convenient when it is sufficient to read the approximate temperature.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention provides a temperature display section in which the length of the light emitting part changes in accordance with the measured temperature and the light emitting part can be displayed in a plurality of colors. The light emitting portion is characterized in that the light emitting portion is displayed in a different color for each predetermined temperature range.

The present invention further includes a temperature display section in which the length of the light emitting part changes in accordance with the measurement temperature and can display the light emitting part in a plurality of colors. According to the present invention, all light-emitting parts corresponding to temperatures below the temperature are displayed in the color of the temperature band to which the measured temperature belongs, and each predetermined temperature band is displayed in a different color. Therefore, it is useful when you want to know the approximate temperature.

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

FIG. 1 is a front view of an electronic thermometer 1 according to an embodiment of the present invention, in which 2 is a temperature sensor, 3 is an LCD analog temperature display section composed of a color liquid crystal, 4 is an LCD digital temperature display section, and 5 is a front view of an electronic thermometer 1 according to an embodiment of the present invention. This is the power switch for starting measurement.

FIG. 2 is a block diagram of the electrical system of the electronic thermometer 1 shown in FIG. It consists of: Analog temperature display section 3
consists of many bar-shaped LCs oriented perpendicular to the direction of temperature change.
It has a configuration in which D elements are arranged, and the lighting and display colors of each LCD element are controlled by a decoder 10, respectively.

Figure 3) is a plan view of the temperature display unit 3 in which different colors are displayed for each temperature range; green for 35°C or higher and lower than 37°C, orange for 37°C or higher and lower than 38°C; °
C and above are displayed in red.

FIG. 4 is a flowchart showing the operation of the embodiment having the above configuration.

In step 11, switch 5 in FIG. 1 is turned on,
Next, in step 12, the temperature sensor 2 of the electronic thermometer 1 is placed on a predetermined part of the human body, and the temperature T is measured.

The measured temperature data is converted into a digital signal by the h/'D converter 6 (FIG. 2) and input to CP'[J7. In step 13, if 6+11 constant ff111 degrees T is less than 35 degrees Celsius, the process branches to step 19, and if the switch 5 is completely turned on, the process returns to step 12 and the temperature is measured again. In this case, color-based display for each temperature band is not performed.

If the measured temperature T is higher than 35°C in step 13, the process branches to step 14, where it is determined whether it is lower than 37°C. That is, 35<T (when 37°C, step 1
Step 4 branches to step 15, and the LCD elements corresponding to the measured temperature T or lower are designated as green in the LCD analog temperature display section 3.

If 37° CAT in step 14, step 1
The process branches to Step 6, and further branches to Step 17 when T<38°C. Here, L corresponds to between 37℃ and the measurement temperature T.
Specify the CD element as orange.

If T≧38℃ in step 16, step 18
The LCD element between 38° C. and the measured temperature T is designated as red.

In step 19, the LCD element whose temperature is below the temperature T measured in step 12 is driven, and furthermore, in steps 15, 17 and 18, the display is performed in the specified color. Generally, body temperature measurement is
Measurement starts from around 35° C. and increases gradually over time, so different colors can be displayed for each temperature range.

When switch 5 is ON in step 20, K returns to step 12 and repeats temperature measurement. Since the measured temperature T gradually increases over time, it is displayed in one color when the temperature range changes (Figure 3 (b)).

In the embodiment described above, a predetermined color is displayed for each temperature range, but as an alternative, all LCD elements may be displayed in the color of the temperature range, that is, one color, as shown in FIG. good.
