Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a thermometer, particularly an infrared thermometer, and more particularly to a device for mounting a disposable thermometer probe cover for covering a probe of a thermometer intended for the eardrum on the tip of the probe. .

[0002]

2. Description of the Related Art In the field of body temperature measurement, conventional armpits,
For contact type thermometers used for temperature measurement in the mouth, rectum, etc., because the measurement time is extremely short, from several seconds to 10 seconds,
Radiation from a subject (human body), in particular, an infrared thermometer excellent in thermal responsiveness, such as a thermopile type, a pyroelectric type, a bolometer type, etc., for the eardrum is being used.

When measuring the temperature in the mouth, rectum, or the like, or when using an infrared thermometer, the tip of the thermometer is inserted into a body cavity (in the mouth, rectum, ear canal, etc.). Then, from the viewpoint of hygiene such as infection prevention between subjects, a cover is attached to the tip of the thermometer each time the temperature is measured, and after the measurement, the cover is removed and discarded.

In the probe cover, a sticking portion is provided on a thin film (in the case of an infrared thermometer, a thin film made of a material that substantially transmits infrared rays), and a sticking portion is provided between the sticking portion. There is a probe cover body provided with a mold member.

In such a probe cover body,
The release member is provided with a probe puncture hole, and by inserting the probe tip, the thin film and the release member are separated, and the thin film is attached to the probe tip.

In order to improve the workability when mounting the probe cover, there is a mounting tool having an insertion hole for receiving the tip of the probe (FIG. 10).

In such a mounting tool, the probe cover body 10 is installed on the insertion hole 1 and the tip of the probe (not shown) is pressed against the thin film from the side of the puncture hole (in the direction of the arrow in the figure). Then, the sticking part 7 on the side of the thin film 6 was separated from the release member 5 and stuck to the probe tip part to cover the probe tip part.

[0008]

In such a mounting tool, the probe cover body is installed on the insertion hole, and the thin film is pressed downward by the probe tip portion to move the thin film film to the probe tip portion. It was attached to.

In this case, since the distance between the probe cover and the insertion hole entrance surface is only a small gap and the sticking portion is dragged toward the center of the insertion hole, a force in the shearing direction acts on the sticking portion, Since the thin film did not peel off smoothly and the thin film was unnecessarily stretched, there were cases in which there was an error in the measured value of body temperature, and the wearing (adhesion) itself could not be performed well.

Further, the thin film covering the tip of the probe was folded in the insertion hole and remained folded in a wrinkle shape even after mounting. Since the way it is folded is not uniform, it is not possible to maintain uniform adhesiveness by sticking the sticking part to the thin film. In addition, even when inserted into the ear, it may be uncomfortable due to the unevenness.

The present invention has been made in view of the above-mentioned problems of the conventional example, and the thin film can be easily peeled off from the releasing member, and is unnecessarily stretched (stretched) when mounted on the probe tip. It is an object of the present invention to provide a probe cover attachment for a thermometer that can be easily and reproducibly applied.

[0012]

In order to achieve the above object, a thermometer probe cover mounting device having an insertion hole at a probe tip portion of a thermometer according to the present invention is provided on the probe insertion side of the insertion hole rather than at the insertion hole. It is characterized in that a space portion having a large diameter is provided.

According to a preferred aspect of the present invention, the edge of the space portion on the probe insertion side is chamfered.

According to a preferred aspect of the present invention, the inner diameter of the space is larger than the probe puncture hole formed in the release member of the probe cover body and smaller than the outer shape of the thin film.

According to a preferred aspect of the present invention, the inner diameter of the space is substantially the same as the inner diameter of the sticking portion of the thin film.

According to a preferred aspect of the present invention, the groove portion is provided at the edge of the space portion on the probe insertion side.

According to a preferred aspect of the present invention, the groove portion is arranged so as to be located between the adhering portions on the thin film.

According to a preferred aspect of the present invention, at least two groove portions are provided on the edge of the space portion on the probe insertion side.
