Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic thermometer, and more particularly, to a body temperature pickup with an adhesive pad which can easily and surely make a temperature-sensitive resistance element adhere to a body surface of a person to be measured.

2. Description of the Related Art Conventionally, to measure the body temperature of an infant, an elderly person, a severely ill patient or the like who has difficulty keeping their body immobile, a body temperature is calculated and displayed from a temperature-sensitive resistance element and the resistance value of the temperature-sensitive resistance element. An electronic thermometer comprising a display unit was used. Then, in order to fix the temperature-sensitive resistance element to the body surface of the subject such as the forehead and chest, the temperature-sensitive resistance element is fixed to the body surface with a tape.

[0003]

However, in the conventional method of tapering the temperature-sensitive resistance element with a tape, the tape must be cut and prepared every time the body temperature is measured. Has a lead wire, so a tape must be stretched around the lead wire, and the work of fixing the temperature-sensitive resistance element is complicated. In addition, although the temperature-sensitive resistance element is fixed with tape, the fixing may not be sufficient and the tape may be peeled off, and in particular, infants and the like may move the body violently and cannot measure a stable body temperature. .

Japanese Utility Model Laid-Open No. 4-116743 discloses a thermometer using an optical fiber. In this thermometer, the thermometer is fixed to the body surface using a double-sided tape. It was difficult to use a double-sided tape. Also, Japanese Patent Application Laid-Open No. 57-93218
Japanese Patent Application Laid-Open Publication No. H11-209,086 discloses an electronic thermometer that is reduced in size, but does not propose any technology for fixing the electronic thermometer to a body surface.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is possible to easily fix a temperature-sensitive resistance element on a body surface of a subject, and even if the body is moved violently. Another object of the present invention is to provide a body temperature pickup with an adhesive pad in which the temperature-sensitive resistance element does not peel off from the body surface.

[0006]

Means for Solving the Problems To achieve the above object, a body temperature pickup with an adhesive pad according to the present invention provides a temperature-sensitive resistance element, and calculates and displays the body temperature from the resistance value of the temperature-sensitive resistance element. A lead wire connected to the temperature display,
An adhesive pad for fixing to the body surface while substantially covering the temperature-sensitive resistance element, and a fastener provided on the adhesive pad for fixing a lead wire, wherein the adhesive pad is a lead wire passing through the lead wire. A hole and a slit for guiding the lead wire to the lead wire hole are formed, and the fastener is fixed to the lead wire hole.

[0007] Preferably, as a fastener of such a temperature pickup with an adhesive pad, a fastener provided with an openable and closable door and a spring which constantly biases the door in the closing direction is used.

According to the body temperature pickup with an adhesive pad of the present invention having the above-described structure, the adhesive pad fixes the temperature-sensitive resistance element in close contact with the body surface, and the fastener is a lead wire coming out of the temperature-sensitive resistance element. The lead wire hole allows the lead wire to pass outside the adhesive pad, and the slit guides the lead wire to the lead wire hole when the adhesive pad is mounted. The lead wire sends a signal detected by the temperature-sensitive resistor to the body temperature display unit, and the body temperature display unit calculates and displays the temperature from the input signal.

Further, the door of the fastener allows the lead wire to pass freely inside, but since the spring urges in the direction to close the door, the lead wire entering inside cannot exit the door.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the body temperature pickup with an adhesive pad according to the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of an electronic thermometer using a body temperature pickup with an adhesive pad according to the present invention, FIG. 2 is a cross-sectional view of an electronic thermometer using a body temperature pickup with an adhesive pad according to the present invention, and FIG. FIG. 4 is a partially enlarged view of a fastener used for a body temperature pickup with an adhesive pad according to the present invention, and FIG. 5 is a perspective view of an electronic thermometer using the body temperature pickup with an adhesive pad according to the present invention. The figure is shown.

In FIGS. 1 and 2, reference numeral 10 denotes a substantially disc-shaped temperature-sensitive resistance element, and a lead wire 20 is provided at the center of the surface side of the temperature-sensitive resistance element 10 (the side opposite to the side in contact with the body surface). The lead wire 20 is connected to a body temperature display unit 30 that includes an A / D converter, a digital display unit, and the like, and that calculates and displays the body temperature from the resistance value of the temperature-sensitive resistance element.

Reference numeral 40 denotes an adhesive pad, the back surface of which is an adhesive surface for attaching the temperature-sensitive resistance element 10 to the body surface. The pressure-sensitive adhesive pad 40 is formed of a material having high heat-retention and a concentric shape larger than the temperature-sensitive resistance element 10. A circular lead hole 41 is formed at the center of the adhesive pad 40, and a slit 42 communicating from the outer peripheral edge of the adhesive pad 40 to the lead wire hole 41 is formed.

A fastener 50 is provided in the lead wire hole 41. The fastener 50 has a cylindrical shape made of a thin and soft metal as shown in FIG. An openable / closable door 51 is provided. As shown in FIG. 4, the door 51 is provided to be openable and closable about a shaft 52, and is constantly urged by a spring 53 in a closing direction. In addition, a door 51 is provided above the free end of the door 51.
A projection 54 is formed so that a finger can be applied when opening and closing the camera.

In order to use the temperature pickup with an adhesive pad as described above, first, a temperature-sensitive resistance element 10 with a lead wire 20 protruding is prepared. Over the temperature-sensitive resistance element 10, and the lead wire 20 is pushed into the lead wire hole 41.
At this time, the door 51 of the fastener 50 is pushed open by the lead wire 20, but is immediately closed by being urged by the spring 53. Therefore, the lead wire 20 does not come off from the lead wire hole 41.

Then, as shown in FIG. 5, the temperature-sensitive resistance element 10 is pressed against the body surface 60 of a predetermined part of the non-measurer, and the adhesive pad 40 is attached to the body surface to fix the temperature-sensitive resistance element 10. And measure body temperature. When the measurement of the body temperature is completed, the adhesive pad 40 is removed, a new adhesive pad 40 is attached to the temperature-sensitive resistance element 10, and the next measurement of the body temperature of the subject is performed.

In the above embodiment, the lead wire hole is formed in the center of the adhesive pad. However, the present invention is not limited to this, and an appropriate portion may be provided so as to correspond to the position where the lead wire of the temperature-sensitive resistance element is arranged. May be formed.

[0017]

As described above, according to the body temperature pickup with an adhesive pad of the present invention, the temperature-sensitive resistance element can be prevented from peeling off from the body surface by an extremely simple operation.
In addition, even if the subject such as an infant moves violently, the temperature-sensitive resistance element does not peel off, and the body temperature can be constantly measured in a stable state.
