no. 1 Embodiment approach
[0042] Hereinafter, this embodiment will be described with reference to the drawings.
[0043] figure 1 It is a block diagram showing the configuration of an electronic thermometer as a temperature measuring device according to the present embodiment.
[0044] The electronic thermometer 2 of the present embodiment has: a thermometer main body 10, which is in contact with the body surface 4A of the human body 4 (refer to image 3 ) contact; In the present embodiment, since the display device 12 is formed separately from the thermometer main body 10 , weight reduction of the thermometer main body 10 that needs to be in contact with the surface of the human body 4 is promoted. Therefore, even if the thermometer main body 10 is in contact with the surface of the human body 4 for a long time, there is no burden, and continuous temperature monitoring for a long time can be realized.
[0045] figure 2 is an enlarged view showing a state where the thermometer main body 10 of this...
Embodiment 1
[0089] Figure 5 It is a figure which shows the thermometer main body 10 and the measurement result of this Example.
[0090] Next, in this embodiment, the measurement results obtained using the thermometer main body 10 will be described.
[0091] The measurement environment in this embodiment is as follows. As a set value, the outside air temperature is 25°C.
[0092] In addition, the temperature of the deep part of the human body 4 (below 10 mm) is 37° C., and the thermal conductivity is 0.3 (W / mK).
[0093] The temperature measurement parts 14A and 14B each have a cylindrical shape with a diameter of 50 mm. On the temperature measurement part 14A, from the body surface 4A side, a silicon material as the heat insulating part 18 with a thermal conductivity of 0.05 (W / mk) and a first heat dissipation control part 18A with a thermal conductivity of 0.01 (W / mk) are stacked. . On the temperature measurement part 14B, from the body surface 4A side, a silicon material as the h...
no. 2 Embodiment approach
[0097] Figure 6 It is a figure which shows the thermometer main body and the measurement result of this embodiment.
[0098] Such as Figure 6 As shown, the thermometer main body 50 of this embodiment has two (a pair) of temperature measurement parts 14A, 14B. The temperature measurement unit 14A has a first heat dissipation control unit 18A provided between the heat insulating units 18 . On the other hand, temperature measurement unit 14B has second heat dissipation control unit 18B provided between heat insulating units 18 . In addition, the structure, surface area, roughness, and the like of the contact surface of each heat insulating portion 18 with the outside air are configured such that the heat transfer coefficients h are equal. The temperature measurement unit 14A has an outside air sensor 25A that measures the temperature of the contact surface 23A of the heat insulating unit 18 with the outside air as the first outside air temperature. Moreover, the temperature...
