Description

[0001]
[Industrial applications]
The present invention relates to a thermometer, particularly an infrared thermometer, and more particularly to an instrument for mounting a disposable thermometer probe cover for covering a probe of a thermometer for an eardrum particularly at a probe tip.
[0002]
[Prior art]
In the field of body temperature measurement, the measurement time is extremely short, about several seconds to 10 seconds, compared to a conventional contact-type thermometer used for measuring the temperature of the axilla, mouth, rectum, etc., so radiation from the subject (human body) In particular, infrared thermometers having excellent thermal responsiveness, such as thermopile type, pyroelectric type, and bolometer type, particularly for the eardrum, are being used.
[0003]
When measuring the temperature of the mouth, rectum, etc., and when using an infrared thermometer, insert the tip of the thermometer into a body cavity (mouth, rectum, ear canal, etc.). Then, from the viewpoint of hygiene such as infection prevention between subjects, a cover is attached to the distal end of the thermometer for each temperature measurement, and is removed and discarded after completion of the measurement.
[0004]
The probe cover has a sticking portion on a thin film (in the case of an infrared thermometer, a thin film formed of a material that substantially transmits infrared light), and a release member is provided through the sticking portion. There is a probe cover body provided.
[0005]
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. Be worn.
[0006]
In order to improve the workability when mounting the probe cover, there is a mounting tool having an insertion hole for receiving a probe tip (FIG. 10).
[0007]
In such a mounting device, a probe cover body 10 is installed on the insertion hole 1 and a probe tip (not shown) is pressed against the thin film from the puncture hole side (in the direction of the arrow in the figure), whereby the thin film is formed. The sticking part 7 on the film 6 side was separated from the release member 5 and stuck to the tip of the probe to cover the tip of the probe.
[0008]
[Problems to be solved by the invention]
In such a mounting device, the probe cover body is placed on the insertion hole, and the thin film is attached to the probe tip by pressing the thin film downward at the probe tip.
[0009]
In this case, there is only a small gap between the probe cover body and the entrance surface of the insertion hole, and the sticking portion is dragged toward the center of the insertion hole. Since the thin film was not stretched unnecessarily and stretched unnecessarily, there was a case where an error occurred in the measured body temperature and the attachment (attachment) itself could not be performed well.
[0010]
Further, the thin film covering the tip of the probe was folded in the insertion hole, and remained folded in a wrinkled shape even after being mounted. Since the folding method is not uniform, it is not possible to maintain uniform adhesiveness by sticking the sticking portion to the thin film. Furthermore, even when inserted into the ear, the user may feel uncomfortable due to the unevenness.
[0011]
The present invention has been made in view of the problems of the above-described conventional example, and can easily peel a thin film from a release member, and does not unnecessarily expand (stretch) at the time of attachment to a probe tip. It is an object of the present invention to provide a thermometer probe cover mounting device that can be adhered to a thermometer with high reproducibility.
[0012]

[0020]
(Example 1)
FIG. 1 is a cross-sectional view of a probe cover mounting device for a thermometer according to a first embodiment of the present invention. FIG. 3 is a perspective view of a disposable probe cover for an infrared thermometer, and FIG. 4 is a sectional view of a disposable probe cover for an infrared thermometer.
[0021]
In FIG. 1, reference numeral 3 denotes a probe cover mounting device for a thermometer, 1 denotes an insertion hole at a probe tip, 2 denotes a space (recess), 2a denotes an edge of the space on the probe insertion side, and 2b denotes a space of the probe insertion side of the space. The opposite edge. The insertion hole 1 at the tip of the probe has substantially the same outer shape (taper shape) as the tip of the probe, and the inner diameter of the edges 2a and 2b of the space 2 is formed larger than the opening 1a of the insertion hole at the tip of the probe. ing.
[0022]
The probe cover body 10 includes a substantially infrared-transparent thin film 6 and an adhesive portion (adhesive layer) 7 provided on the thin film 6 for mounting the thin film 6 at a predetermined position on the tip of the thermometer probe. And a release member 5, which is large enough to cover the probe tip.
[0023]
The thin film 6 is made of a thin synthetic resin material or the like which is substantially excellent in infrared transmittance and flexibility. For example, polyethylene is preferably used. The thickness is preferably 5 to 70 μm, particularly preferably 5 to 30 μm. If the thickness is less than 5 μm, there is a problem in strength, and if it exceeds 70 μm, it is not preferable because the flexibility is lowered and the infrared transmission characteristics are lowered.
[0024]
A sticking portion 7 is applied or stuck to the upper surface of the cover so that the sticking portion 7 can be adhered to the side surface of the probe tip 9. The sticking portion 7 is preferably one having an appropriate degree of tackiness that does not come off during temperature measurement after being attached to the probe tip portion 9 and is easily peeled off after temperature measurement. For example, acrylic rubber, styrene butadiene-based It is only necessary that a synthetic rubber-based adhesive such as rubber is applied, or that an appropriate sheet or film, such as an adhesive tape, which itself exhibits adhesiveness is adhered.
