Field of the Invention The present invention relates to a radiation thermometer, and more particularly to an infrared thermometer in which a disposable cover for covering the tip of a probe inserted into the ear during temperature measurement can be easily attached and detached. .

[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 using these types of infrared thermometers, the tip of the thermometer is inserted into the ear canal. 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.

Regarding the cover, Japanese Patent Laid-Open No. 61-263
Japanese Patent No. 438 discloses that a relatively hard tubular portion is provided with an infrared ray permeable film at its tip. In addition, as a disposable probe cover assembly, special table 4-
No. 502206, and Japanese Patent Laid-Open No. 3-133425 as a cover for the speculum.

Although there is a base portion, a peripheral portion, and a peripheral portion having an open end as described in Japanese Patent Publication No. 5, the shape is complicated and the cost is high, and it extends a little along the probe tip portion of the thermometer when the cover is attached. However, there is a problem in that the manual operation of is complicated.

A sheet-shaped probe cover for a disposable infrared thermometer is disclosed in Japanese Unexamined Patent Publication No. 5-317267, but the pedestal is used by being fitted to the fitting portion of the probe of the infrared thermometer. Therefore, the subject is uncomfortable.

When these are attached to a thermometer, they are made of a relatively rigid plastic tubular portion although they have an infrared ray permeable membrane near the tip end thereof, and they lack good insertion feeling. In addition, since the cover has a large thickness, the diameter of the probe inserted into the ear is consequently thick, and the probe cannot be inserted to a predetermined position sufficiently, which hinders stable measurement. In addition, the membrane itself has drawbacks such as a complicated operation due to some force work for extending along the distal end of the thermometer when the cover is attached, and a complicated structure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

FIG. 1 is a diagram showing a probe part equipped with a probe cover of a thermometer according to an embodiment of the present invention and its vicinity, and FIG. 4 is a probe part of a thermometer according to an embodiment of the present invention and its vicinity. It is a figure.

A probe formed of a thin film having substantial infrared transparency for covering at least the infrared transmission part 1c provided at the tip of the probe part 1 at approximately the center part 1a of the probe part 1 of the infrared thermometer 10. A positioning member 2 for mounting and positioning the cover 4 is provided.

As shown in FIG. 3, the probe cover 4 is made of a thin synthetic resin material or the like which is substantially transparent to infrared rays and has excellent flexibility, and polyethylene, for example, is preferably used. The thickness is preferably 0.5 to 50 μm, particularly preferably 1 to 30 μm. When it is thinner than 10 μm, there is a problem in strength, and when it exceeds 50 μm, it is not preferable because the flexibility is lowered and the infrared transmitting property is lowered.

The shape of the probe cover 4 may be an n-gon other than a quadrangle (where n is an integer), a substantially circular shape or the like as long as it can cover the probe tip portion 1b.

The probe covers 4 may be separated from each other, but may be continuously formed in a roll shape as shown in FIG. When formed in a roll shape, as shown in FIG. 7, it can be stored in a case 52 for storing a probe cover having an insertion hole 51 and a mounting base 5 for use. 7A is a cross-sectional view showing the internal structure of the mounting base 5, FIG. 7B shows the appearance of the case 52, and 8 is a dial for driving the probe cover.

FIG. 6A shows a continuous probe cover 4
In the figure, substantially circular perforations 6 of substantially the same shape are formed at predetermined intervals, and in FIG. 6B, substantially rectangular perforations 6 are formed at predetermined intervals.

In order to easily attach the probe cover 4 to the probe tip 1b, the probe cover 4 is placed on the mount 5 having an insertion hole 51 into which the probe tip 1b can be inserted, as shown in FIG. The probe cover 4 is attached to the probe tip 1b by pressing the probe cover 4 toward the insertion hole 51.

The insertion hole 51 has a predetermined shape that is optimal for a sticking portion (not shown) provided on the surface of the positioning member 2 of the probe portion 10 to adhere to the side surface of the probe tip portion 1b. It is preferable that the shape substantially conforms to the shape of the portion 3, and thus the diameter is smoothly reduced toward the inside of the case 52, but outside the probe at the position where the sticking portion provided on the surface of the positioning member 2 abuts. The pore size may be substantially matched to the diameter.

Further, as shown in FIG. 8, the probe cover 4 is continuously formed into a roll shape, and a protrusion 52 is arranged on a part of the mounting base 5 as a probe cover locking portion on the upper surface of the mounting base 5. The holes 61 are provided at positions substantially corresponding to the protrusions 52, and the perforations 6 are provided substantially at right angles to the longitudinal direction at almost predetermined intervals, so that adjacent probe covers 4 as shown in FIG.
It is also possible to easily separate a and 4b.

One or more, preferably two, protrusions 52 are provided at any position on the upper surface of the mounting base 5 except the insertion hole 51. By providing the position near the end of the mount 5, the probe cover 4 can be easily attached to the probe tip 1b. The shape of the protruding portion 52 is preferably a substantially truncated cone shape for easy insertion.

The surface of the insertion hole 51 is made of a relatively soft synthetic resin such as silicone rubber so that the probe cover 4 can be easily attached to the probe tip 1b.

Although the positioning member 2 is provided at a predetermined distance from the infrared ray transmitting portion 1c, that is, substantially in the center 1a of the probe portion 1 in FIG. 1, the infrared ray transmitting portion 1c is substantially entirely covered. It may be located at any position on the outer wall of the probe 1 as long as it is possible.

A sticking portion (not shown) is applied or stuck on the surface of the positioning member 2 so that the probe cover 4 can substantially cover the entire infrared ray transmitting portion 1c.

After the probe cover is attached to the probe 1, the sticking portion is preferably one that does not come off during the temperature measurement and has an appropriate strength of adhesiveness that easily peels off after the temperature measurement.
For example, double-sided adhesive tape, synthetic rubber adhesive such as acrylic rubber, styrene-butadiene rubber, etc. may be applied, or adhesive tape or other suitable sheet or film showing adhesiveness may be applied. Used.

Further, the sticking part can be made of a material such as water or alcohol which does not substantially reduce the adhesiveness even after cleaning and disinfection.

In order to prevent dust and the like from adhering to the adhesive portion before use, it is preferable to protect the adhesive portion by covering it with a thin film made of synthetic resin which is easy to peel off.

In use, when the adhesive portion has a reduced adhesiveness due to the adhesion of dust or the like, the positioning member 2 is moved as shown in FIG.
It is also possible to remove the mounting portion 3 for mounting and replace it.

The mounting portion 3 is preferably formed by an annular recess for easily mounting the positioning member 2 at a predetermined position.
