Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermometer for measuring body temperature in an ear canal.

[0002]

2. Description of the Related Art As one of the means for measuring body temperature, the eardrum temperature in the ear canal is measured. This is because eardrum temperature is a kind of core body temperature and has clinical significance that it can be used as an index of brain temperature. The eardrum temperature is measured by detecting the amount of infrared rays emitted from the eardrum because it is practically impossible to measure the temperature by bringing the thermometer into contact with the eardrum. A conventional thermometer for this purpose has a structure in which a probe inserted into an ear canal is integrally formed so as to project from a case, and a sensor for detecting infrared rays from the eardrum is provided in the probe.

[0003]

Since the conventional thermometer has a structure in which the probe projects from the case, it is bulky and inconvenient to carry and store. Also,
Since the protruding probe is weak in strength, it has a problem that it easily breaks and easily breaks down. Further, there is a limit to miniaturization, and it is difficult to improve the external design.

The present invention has been made in consideration of the above circumstances, and provides a thermometer which is convenient for carrying and storing by eliminating the protrusion of the probe, is free from breakage of the probe, and can be reduced in size and improved in design. The purpose is to do.

[0005]

In order to achieve the above object, the present invention has a structure in which a probe is foldable, and includes a case having an accommodating recess formed on its outer surface and a sensor for detecting infrared rays. A probe that is disposed inside and is housed in the housing recess of the case and that is rotated to stand up from the housing recess; and a display member that is arranged in the case and that displays the body temperature value detected by the sensor. Characterize. Further, the present invention provides a case having a storage recess formed on an outer surface thereof, a probe which is placed inside the storage recess of the case and is housed in the storage recess of the case and which is rotated to stand up from the storage recess, and the case. A display member for displaying a body temperature value, a circuit board for outputting a display signal of the body temperature value to the display member based on a detection signal of the sensor, and a switch member for switching ON / OFF of the body temperature measurement It is also characterized by that.

1 and 2 show one embodiment of the present invention,
The case 1 and the probe 2 attached to the case 1 form the external appearance of the thermometer. The case 1 is made lightweight by being made of a synthetic resin, and a storage recess 3 is formed in a front surface portion (right side portion in the illustrated example) of the case 1. Further, a display window 4 is opened in a back surface portion (left side portion in the illustrated example) of the case 1, and a display member 5 is arranged inside the case 1 facing the display window 4. The display member 5 displays the body temperature measured in the ear canal by a numerical value, a graph, or the like. In the illustrated example, a liquid crystal display device is used to reduce the thickness.

The probe 2 has a base end portion attached to the housing recess 3 of the case 1. Probe 2
Is inserted into the ear canal at the time of body temperature measurement, and is molded into a smooth outer shape with a synthetic resin to facilitate insertion into the ear canal. A sensor 6 for detecting the amount of infrared rays emitted from the eardrum in the ear canal is provided inside the probe 2.
Is provided. The sensor 6 includes a light guide tube 7 that is axially inserted into the probe 2. The light guide tube 7 guides infrared rays to the sensor 6, and a metal tube body having an open front end surface is used.

In such a probe 2, the base end portion 2a has a case 1
It is inserted and attached in the storage recess 3 of. This attachment is performed by penetrating the spring pin 8 into the base end portion 2a of the probe 2 and inserting both sides of the spring pin 8 into the case 1, whereby the probe 2 becomes rotatable with respect to the case 1. ing. On the other hand, the storage recess 3 of the case 1 is formed in a size and shape capable of storing the entire probe 2, and the probe 2 is stored in the storage recess 3 as shown by the chain line in FIG. It will not project outside. This makes it convenient to carry and store, and can be downsized. Moreover, since the probe 2 does not come into contact with external materials, breakage and the like can be prevented, and since the protruding portion is eliminated, the entire thermometer can have a neat and functional shape, and the appearance design can be improved. On the other hand, by rotating the probe 2 in the pull-out direction, the probe 2 can be erected from the storage recess 3 as shown by the solid line in FIG.
Can be inserted into the ear canal to measure body temperature.

In FIG. 2, reference numeral 9 is a circuit board arranged in the case 1, and is an LSI for controlling the operation of the entire thermometer.
10 is mounted and connected to a battery (not shown) provided in the case 1. The sensor 6 in the probe 2 is electrically connected to the circuit board 9 by the flexible connection board 11, and the detection signal detected by the sensor 6 is sent to the circuit board 9. On the other hand, the circuit board 11 is electrically connected to the display member 5 via a connecting member 12 such as an interconnector. As a result, the circuit board 11 outputs a display signal to the display member 5 based on the input of the detection signal from the sensor 6, and the display member 5 displays the body temperature value by the input of the display signal.

A switch member 13 is provided on the upper surface of the case 1. The switch member 13 has a push button portion 13a having elasticity capable of being deformed by depression, a movable contact 13b provided on the lower surface of the push button portion 13a, and a switch substrate 13c having a fixed contact 13d facing the movable contact. And the switch substrate 13c has a connection line 1
It is connected to the circuit board 9 via 4. When the switch member 13 presses the push button portion 13a, the movable contact 13b comes into contact with the fixed contact 13d. Thereby, the measurement of the body temperature is started, and the display member 5 displays the body temperature value based on the detection signal from the sensor 6. Then, following this pressing operation, the pressing is performed again, whereby the body temperature measurement is stopped, and the display on the display member 5 ends. By providing such a switch member 13, since the body temperature is not measured and displayed when it is not needed, unnecessary battery consumption can be prevented.

The present embodiment as described above has a structure in which the probe 2 is stored in the storage recess 3 of the case, and the probe 2 is rotated to stand up only at the time of measurement, so that unnecessary protrusion of the probe 2 is eliminated. In addition to being convenient to carry and store, the probe 2 is not broken, and the size and design can be improved.

The present invention can be variously modified without being limited to the above embodiments. For example, a switch element for detecting whether the probe 2 is stored in the storage recess 3 and standing up from the storage recess 3 is provided, and the body temperature is measured when the probe 2 is stored in the storage recess 3.
The behavior of the probe 2 and the body temperature measurement may be interlocked so as to be FF and to be turned ON when standing up. Such a switch element can be provided, for example, in the spring pin 8 part,
By disposing the switch element, the switch member 13 is not required, so that operability and appearance are improved.

[0013]

According to the present invention, since the probe provided with the sensor can be stored and erected in the storage recess of the case, it is convenient for carrying and storing, and the probe can be prevented from being damaged, and the size and appearance can be improved. Become.
