DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermometer, and more particularly to an intraocular thermometer for measuring infrared rays from the ear canal and / or the eardrum.

[0002]

BACKGROUND OF THE INVENTION For the diagnosis and monitoring of many illnesses, it is useful to quickly and accurately read the temperature of the human body, and in this regard, in recent years, in recent years, the eardrum and / or the vicinity of the eardrum, ie, substantially from the eardrum, Infrared thermometers that measure body temperature by detecting infrared rays have been developed.

[0003]

However, the shape of the human ear canal, including the inner diameter and length, of the human ear canal greatly varies depending on race, gender, age, and the like. Since the provided probe part has a fulcrum only in the part that comes into contact with the ear, the direction and position of the infrared sensor are not fixed, and it moves carelessly every time the temperature is measured, so the reproducibility of the measured temperature is poor. was there.

The present invention has been made in view of the above problems, and has as its object to provide an in-ear thermometer in which the directionality and positioning of an infrared sensor are easy.

[0005]

Means for Solving the Problems The present invention for achieving the above object, a body portion having at least the grip portion, the main
A ear thermometers for detecting infrared radiation from the ear canal and / or tympanic membrane substantially "Ku" consisting of a temperature measuring probe portion provided at a distal end of the extending been neck in shape from the body portion, the subject When the temperature measuring probe is inserted into the ear to measure the temperature, a part of the main body has a convex shape and forms a fulcrum by contacting a part of the body of the subject. In-ear thermometer.

A power supply is further provided, wherein the power supply is a battery, and the position of the battery is an in-ear thermometer having a substantial center of gravity.

[0007] Further, a power switch unit and a measurement start switch unit are provided.
This is an in-ear thermometer provided substantially on the left and right symmetric axes of the main body, and provided at a position substantially supporting the center of gravity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an in-ear thermometer according to an embodiment will be described in detail with reference to the accompanying drawings. FIG. 1 is an external perspective view showing an embodiment of the present invention. A probe unit 5 having a temperature measuring unit (not shown) including an infrared sensor is provided at one end 6a of the main body 1.

A temperature measuring probe section 5 is provided at the tip of a neck section 1a extending substantially in the shape of a "-" from the main body section 1.
The temperature measuring probe section 5 smoothly reduces its diameter toward the tip section 5a, and houses an infrared sensor such as a thermopile inside the tip section.

The material of the probe section 5 is a relatively hard synthetic resin such as ABS resin, polyurethane, polycarbonate, polypropylene, etc .; a relatively soft synthetic resin such as soft vinyl chloride resin or silicone resin; Metal materials such as alloys, titanium, titanium-based alloys, brass, and copper are appropriately used.

The main body 1 includes a control circuit for processing temperature information from an infrared sensor (not shown), a measurement circuit power supply unit, a control unit, and the like. On the outer surface of the main body 1,
A measurement start switch unit 3 for starting temperature measurement and a power switch unit 4 are provided.

The measurement start switch unit 3 is formed by a button switch such as a tact switch, and the power switch unit 4 is
It has a concave shape so that the power is not accidentally turned off, and a switch button is provided therein.

A display section 2 such as a liquid crystal for displaying a temperature, an error or the like is provided at an end 1b opposite to the end 1a at which the probe section 5 is provided.

At the time of use (at the time of temperature measurement), the user holds the grip 7 of the main body 1, turns on the power switch 4, and connects the tip 5 a of the temperature measurement probe 5 to the ear canal of the subject (not shown). To the predetermined position.

At this time, the proximal end 5b of the temperature measuring probe 5
And the two points of the arcuate portion 6 formed in an arc shape are brought into contact with a part of the body of the subject (such as the side of the face) and pressed to become a fulcrum, and the ear of the tip 5a of the temperature measurement probe 5 The direction and position of the infrared sensor are determined by determining the position in the interior. In this state, the measurement start switch 3 is turned on, infrared rays emitted from the external auditory canal and / or the eardrum are detected, and the body temperature (body temperature in the ear) is obtained in one to ten and several seconds based on the detected infrared rays.

The arc-shaped portion 6 may have any shape as long as it forms a fulcrum such as a convex shape.

The material of the main body 1 may be the same as the material of the probe 5, or a relatively hard synthetic resin such as ABS resin, polyurethane, polycarbonate, polypropylene, or the like.
Metal materials such as aluminum, aluminum-based alloy, titanium, and titanium-based alloy are appropriately used.

A power supply section (not shown) is provided inside the lower portion of the main body 1 and has the power supply section as a center of gravity. As the power supply unit, a manganese battery, an alkaline battery, a silver battery, a rechargeable NiCd battery or the like is used.

The in-ear thermometer of the present invention can be applied to an in-ear thermometer using any type of infrared sensor such as a bolometer type and a pyroelectric type.

[0020]

As has been described above in detail, ear thermometer according to the present invention includes a main body portion having at least the grip portion, said body
A ear thermometers for detecting a substantially "Ku" infrared radiation from the ear canal and / or tympanic membrane consisting of a temperature measuring probe portion provided at a distal end of the extending been neck in shape from parts, the subject of the ear When measuring the temperature by inserting the temperature measurement probe into the
Since a part of the body portion is characterized in that to form a fulcrum in contact with a part of it of the subject body a convex shape, temperature measuring probe of the time measured by aural (ear canal) Direction and positioning are easy, and more accurate body temperature in the ear can be measured.

Since the power supply unit is a battery, and the position of the battery is substantially at the center of gravity, there is a sense of stability when the main body is gripped during the measurement, and the inner ear (the external auditory canal) during the measurement. In), the directionality and positioning of the temperature measurement probe section are further facilitated, and more accurate measurement of body temperature in the ear can be performed.
