[0002]

2. Description of the Related Art The radiation thermometer has a probe for connecting to an ear canal of a human body. This probe also has a function of guiding infrared rays emitted from the inner ear to the measurement unit. Probes used in conventional radiation thermometers are classified into, for example, medical, children, and home use, each having a fixed size.

[0003]

The radiation thermometer of the above-mentioned conventional construction has a problem that accurate measurement cannot always be performed because the probe size is fixed.

That is, the size of the ear canal is different between adults and children, and between women and men. Also, the degree of bending of the ear canal varies depending on the individual. Therefore, when one determined probe is used, the fit varies depending on the individual. For this reason, the insertion position of the probe may be different each time, and the reliability of the measured value may be reduced. In addition, for example, in the case of an infant or the like, the mother inserts the probe into the ear canal to measure the body temperature, but in this case, it is unclear how much should be inserted inside.

[0005]

According to the present invention, an auxiliary probe corresponding to a measurer is provided in a probe section provided in a main body section,
It is a radiation thermometer that can measure accurately.

In the main body 1, an infrared sensor 7 for receiving infrared light guided by the probe unit 2, a window 7a provided in the infrared sensor 7, and a shielding plate 1 for shielding the front surface of the window 7a.
1 and a shield driving means 12 for vertically driving the shield 11
And a temperature measuring means 13 for measuring the temperature of the infrared sensor 7
And a body temperature measuring unit 9 for measuring a body temperature by receiving signals from the infrared sensor 7 and the temperature measuring means 13. The body temperature measurement unit 9 has a microcomputer 9a, and connects the buzzer 10, the display unit 3, the power switch 4, and the measurement start switch 5 shown in FIG.

In the present embodiment, an auxiliary probe 8 as shown in FIG.
In this embodiment, the auxiliary probe 8 is formed by molding a resin such as polypropylene, but there is no particular limitation on the material. The auxiliary probe 8 is prepared in various sizes and shapes for children, adults and the like. At the end of the auxiliary probe 8, a stepped portion 8a as shown in FIG. 3 is provided. The step processing part 8a is identical to the step processing part 2a of the probe unit 2 shown in FIG. The step processing unit 8a and the step processing unit 2a
When the auxiliary probe 8 is connected to the probe section 2, the connecting means constitutes connection means for ensuring the connection. FIG. 5 is a perspective view showing a state where the auxiliary probe 8 is connected to the probe unit 2. The user connects the auxiliary probe 8 to the probe unit 2 so that the step processing unit 8a of the auxiliary probe 8 matches the step processing unit 2a of the probe unit 2.

The operation of this embodiment will be described below. When the user presses the power switch 4, holds the main body 1, inserts the probe 2 into the ear canal, and presses the measurement start switch 5, the radiation thermometer of this embodiment starts operating. That is,
When the measurement start switch 5 is pressed, the body temperature measuring section 9 sends a drive pulse signal to drive a motor constituting the shield driving means 12. The shield driving means 12 operates continuously for a predetermined time after the measurement start switch 5 is pressed. When the shield driving means 12 operates, the shield 11 that opens and closes the light receiving window 7a of the infrared sensor 7 operates. The infrared signal thus incident from the light receiving window 7a is received by the infrared sensor 7. The infrared sensor 7 receives this signal and transmits a temperature signal corresponding to the received signal to the body temperature measuring unit 9. At this time, the temperature of the infrared sensor 7 rises when receiving the infrared ray radiated from the inner ear, and the temperature signal transmitted to the body temperature measurement unit 9 includes the temperature rise. Therefore, the temperature measuring means 13 is used to correct the temperature rise.
The temperature measuring means 13 measures the temperature of the infrared sensor 7 and transmits this temperature signal to the body temperature measuring unit 9. Microcomputer 9 constituting body temperature measuring unit 9
“a” calculates the body temperature from the signal of the infrared sensor 7 and the signal of the temperature measuring unit 13 and displays the calculation result on the display unit 3. In this way, the buzzer 10 operates after the predetermined time elapses, and the user can recognize the end of the measurement, and can see the display on the display unit 3 to know the body temperature.

In this embodiment, the predetermined time for driving the shield driving means 12 is set to 3 seconds. In this embodiment, a pyroelectric infrared sensor is used as the infrared sensor 7. Therefore, as described above, the light receiving window 7a is opened and closed by the shielding plate 11 and the shielding plate driving means 12. That is, when an infrared sensor other than the pyroelectric type is used, it is not necessary to open and close the light receiving window 7a. In the present embodiment, the temperature of the infrared sensor 7 is detected by the temperature measuring means 13. However, when an infrared sensor other than the pyroelectric type is used, no correction is necessary. 13 need not be used.

At this time, in this embodiment, the auxiliary probe 8 is used when the user has a sense of incongruity due to improper dimensions when the probe 2 originally attached is used. The auxiliary probe 8 is prepared in various sizes as described above. The size of the probe part originally attached is as follows: the diameter of the connection side with respect to the main body part 1 side is 15 mm, the diameter of the ear insertion side is 8 mm, and the length is 25 mm.
In this embodiment, the auxiliary probe 8 has a diameter of 8 m in this embodiment.
m, an extension length of 2 mm, 4 mm, 8 mm, etc. are prepared. Therefore, if the user feels uncomfortable with the probe unit 2 inserted into the ear before measurement, an appropriate type of auxiliary probe 8 can be used. When the auxiliary probe 8 is connected to the probe 2, a predetermined step processing portion 8 a provided on the auxiliary probe 8 is connected so as to match the step processing portion 2 a provided on the auxiliary probe 2. The dimensions can be maintained.

As described above, according to the present embodiment, a radiation thermometer capable of accurate measurement can be realized by using the auxiliary probe 8 which conforms to the shape of the user's ear canal.
