Description

Ear thermometer

The present invention relates to an ear thermometer.

A thermoresistor for detecting an ambient temperature temperature detecting element and a thermopile for detecting an infrared detecting element (cold junction and hot junction) of infrared rays radiated from the temperature measuring unit in the ear cavity It is built into the probe and measures the body temperature based on the detection result of each detected component. The ear thermometer thus constructed has reached a practical stage.

The applicant of the present application has applied an ear thermometer, which is a thermal resistor for the temperature detecting component, and a thermopile formed by the cold junction and the hot junction is respectively disposed at a position away from the probe opening, and is introduced into The infrared rays of the probe opening are guided to the thermopile by the light guide tube, thus constituting the ear thermometer.

According to this configuration, the outer diameter of the end face forming the opening at the tip end of the probe can be reduced, so that it can be inserted into the ear cavity. Moreover, if the probe is inserted into the ear cavity, the body temperature can cause heat conduction to the probe, so that the correct body temperature measurement cannot be performed. However, as described above, the infrared light guided to the probe opening is guided to the probe for the thermopile in a separate state, and the body temperature can be measured even if the probe has body temperature heat conduction. (Patent Document 1).

However, as in the above case, each of the detecting elements is disposed at the root of the probe, and the gold-plated light guide tube is disposed inside the probe. Avoid the increase in the number of parts and the increase in processing costs. Therefore, in order to reduce the number of components including the light guide tube and reduce the cost, the detection elements can be directly placed in the probe opening to reduce the size of each detection element. Therefore, a structure of an ear thermometer is proposed, and each of them is detected. The component is attached to the opening adjacent the probe.

On the other hand, when the detection elements are fixed to the vicinity of the probe opening, the probe opening is used as a medium, and foreign matter or liquid enters the inside of the probe. The influence of the detection is not possible, and the accurate body temperature measurement cannot be performed. In particular, it is necessary to maintain a liquid-tight state for cleaning the probe opening with a cotton bat that is impregnated with alcohol. When this cleaning is performed, the force applied to the inside of the probe must be sufficiently resistant.

Therefore, the device base portion 23 is a good heat conduction system such as an aluminum material, and is capable of transmitting the outside air temperature, and at the same time, increases the surface area of the device of the thermal resistance 21 when it is fixed. After this is fixed, The lead wire 28 to which the base member 23 is fixed in an insulated state is connected to the lead of the thermal resistor body 21.

On the other hand, when the infrared detecting element 22 for detecting infrared rays (IR) is detected, the absolute temperature cannot be detected, and only the relative temperature change can be detected. Therefore, the body temperature is the temperature detected by the temperature detecting element plus the temperature detected by the infrared detecting element. The details of the detection operation are described in detail in Japanese Laid-Open Patent Publication No. Hei 11-123179, and are hereby omitted.

Here, according to the detection element housing 20 shown in the drawing, the device base member 23 is formed with the outer shank portion 23a, and is extended from the edge portion of the base member 23 in the radial direction to approximately the entire circumference, and the back surface thereof is referred to as a fixing portion. Even if the outer shank portion 23a is absent, the device base member 23 having the same diameter of the outer peripheral surface 25a of the container member 25 constitutes the detecting element housing 20. Further, at least two protrusions may be extended in the radial direction.

Then, the back surface 23c of the apparatus base 23 is fixed to the joint portion 33 and fixed. That is, as shown in Fig. 8C, the back surface 23c of the apparatus base member 23 is supported by the three joint portions 33.

As described above, as shown in FIG. 8B, the air layer K may be formed on the inner side surface portion 34 of the probe 3 and the outer peripheral surface 25a of the container member 25.
