Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to the structure of a probe cover of a radiation thermometer that measures body temperature by detecting infrared rays of a living body.

[Conventional technology]

In recent years, thermometers have been digitized and the spread of digital thermometers has been rapidly increasing. Compared to the conventional mercury thermometer, the electronic thermometer is advantageous in that it is less likely to be damaged, is safe even if it is damaged, and has an easy-to-read display. In addition, the development of a predictive electronic thermometer using a microcomputer has reduced the measurement time. However, since all of these methods use contact temperature measurement, there is a limit in reducing the measurement time. What has been devised there is a radiation thermometer that performs non-contact measurement. Normally, a radiation thermometer that detects infrared radiation emitted from an object and measures the temperature can measure the temperature instantaneously, and by using this method as a thermometer, the measurement time can be greatly reduced. Was. However, when measuring the body temperature of a living body, it is necessary to select a measurement site such as an ear or the like which is less affected by the outside air temperature. Furthermore, in order to measure the temperature in the hole, a probe having a shape to be inserted into the hole is required.When used for an unspecified number of people such as hospitals, the probe portion is hygienic. It is necessary to disinfect each measurement or use a probe cover. However, in hospitals, disinfecting the probe part every measurement is troublesome and troublesome, so that a disposable probe cover is generally used.

A probe cover of a conventionally devised ear thermometer is shown in, for example, US Pat. No. 4,662,360, and the structure of the probe portion is shown in FIG. In the figure, a probe cover 7 attached to a probe 4 of a radiation thermometer comprises an infrared transmitting film 7a and a cylindrical member 7b.
It is mounted so as to cover the entire part. The cylindrical member 7b has a tapered cylindrical shape, and is formed of a plastic such as polyethylene. Further, an infrared transmitting film 7a is attached to the end face on the tip side of the probe 4. When used once, the probe cover 7 is contaminated with hair and debris of the ear canal, which is not only unfavorable for hygiene but also needs to be replaced in order to maintain the measurement accuracy.

[Problems to be solved by the invention]

The plastic probe cover 7 is a cylindrical member.
An infrared transmitting film 7a is attached to one end face of 7b. However, when the probe cover 7 made of a plastic material is attached to the probe 4 as described above, there is a problem that a portion to be inserted into the hole becomes thick, and the shape of the probe cover 7 is changed to an optimal shape suitable for a measurement site. Need to be designed. Also, when the measurement site is a small hole such as an ear hole, the probe cover 7 must be shaped to fit into the ear. However, in this case, the diameter of the probe 4 must be considerably reduced, and the performance is maintained. Design for it was difficult. That is, since the probe cover 7 has to be designed according to the outer shape of the probe 4, a probe having a shape suitable for the measurement site may not be produced. In addition, for the purpose of plastic molding, a certain number of parts are connected together in consideration of ease of handling after molding or at the time of use.However, there is a problem that the overall size becomes large and the storage space becomes large. there were.

The present invention solves the above-described problems, allows the probe of the radiation thermometer to have an optimal shape and size suitable for the measurement site, and requires a smaller storage space than the conventional probe cover. It is an object to provide a probe cover for a radiation thermometer.

[Means for solving the problem]

In order to achieve the above object, the present invention has the following configuration. That is, in the probe cover attached to the probe of the radiation thermometer, the probe cover is a thin sheet-shaped film attached so as to cover the probe, and is fitted around the probe to fix the film to the probe. The film is disposed at a position covering the hole of the fixing member, and when the probe abuts with a predetermined stress or more, the film contacts the hole of the fixing member. It is configured to cover the entry probe. Further, it is desirable that the fixing member be capable of separating a part where the hole is formed. Further, the film may be configured to be held between the fixing member and the sheet member.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First Embodiment FIGS. 1A to 1C are drawings of a probe cover of a radiation thermometer showing a first embodiment of the present invention. FIG. 1A shows a thin sheet-like infrared transmitting film 1 which is attached so as to cover the probe, and has a necessary and sufficient size to cover the probe with a film made of a material such as polyethylene. . FIG. 1 (b) shows a fixing member 2 for fixing the infrared transmitting film 1 to the probe.
, And is formed substantially the same as or slightly larger than the infrared transmitting film 1 and has a hole 2a engaged with the outer periphery of the probe. FIG. 1 (c) is a cross-sectional view of a completed probe cover obtained by combining the infrared transmitting film 1 and the fixing member 2 with each other.
The infrared transmitting film 1 is disposed on the upper side and is fixed by the bonding portion 3. The bonding portion 3 bonds the outer periphery or several portions of the outer periphery so as to be peeled off with a small force. Numeral 4 indicates a probe of the radiation thermometer, and arrow A indicates a direction in which the probe 4 is inserted into the probe cover. Reference numeral 5 denotes a mounting table on which the probe cover is mounted when the probe cover is mounted. The mounting base 5 is provided with a hole 5a under the hole 2a of the fixing member 2 for escape when the probe 4 is inserted.

How to use the probe cover of the radiation thermometer having the above configuration will be described.

First, as shown in FIG. 1 (c), the probe cover is placed on the mounting table 5 with the infrared transmitting film 1 facing upward. Next, the probe 4 of the radiation thermometer is inserted in the direction of arrow A from above. Then, the infrared transmitting film 1 is pulled together with the probe 4 into the hole 2 a of the fixing member 2. At this time, the adhesive portion 3 of the outer peripheral portion of the infrared transmitting film 1 is peeled off by the pulling force and enters the hole 2a.

FIG. 2 is a sectional view of the probe cover of the present embodiment mounted on the probe 4 of the radiation thermometer.

Since the probe 4 is covered with the sheet-like thin film 1 and fixed so as to be fixed by the fixing member 2 in this manner, the shape of the probe 4 hardly changes. It can be shaped to fit the hole. Further, as shown in FIG. 1 (c), the probe cover before use is in the form of a sheet having a certain thickness, so that it is easy to handle and requires less space for storage.

In this embodiment, the fixing member 2 is made of cardboard, but it is not always necessary to use cardboard. Similar effects can be obtained by using a plastic sheet material or an injection molded product.

Second Embodiment FIGS. 3A and 3B are views of a probe cover of a radiation thermometer showing a second embodiment of the present invention. FIG. 3A shows a thin sheet-like infrared transmitting film 1 attached so as to cover the probe, which is similar to FIG. 1A in the first embodiment. FIG. 3 (b) shows a fixing member 2 for fixing the infrared transmitting film 1 to the probe, and has the same role as FIG. 1 (b) in the first embodiment. The member 2 is composed of a fixing member 2e having a hole 2a fitted into the outer periphery of the probe and an outer portion 2b, and both are connected only at the bridge 2c, so that they can be separated when a certain force is applied. It has become.

The infrared transmitting film 1 and the fixing member 2 are bonded together in the same manner as in FIG. 1C of the first embodiment to form a probe cover, and are attached to the probe of the radiation thermometer in the same manner as in the first embodiment. . Then, by holding and pulling the outer portion 2b after mounting, the portion of the bridge 2c is cut off, and the unnecessary outer portion 2b of the fixing member 2 can be removed, and the infrared transparent film 1 and the fixing portion are provided on the probe side of the radiation thermometer.
Only 2e is in a mounted state. Therefore, since the infrared transmitting film 1 is held by the small fixing portion 2e, it becomes easy to insert the probe into the hole of the human body. Further, since a portion to be gripped can be formed in a part of the fixing portion 2e, the probe cover can be easily removed.

In the case where a release mechanism for removing the probe cover is provided on the radiation thermometer side, it is not necessary to form a portion to be gripped by the fixing portion 2e.

Third Embodiment FIGS. 4 (a) to 4 (c) are drawings of a probe cover of a radiation thermometer showing a third embodiment of the present invention. FIG. 4A shows a thin sheet-like infrared transmitting film 1 attached so as to cover the probe, which is similar to FIG. 1A in the first embodiment. FIG. 4 (b) shows a fixing member 2 for fixing the infrared transmitting film 1 to the probe, which has the same role as that of FIG. 3 (b) in the second embodiment, but has bonding portions on both sides. 2d is installed. FIG. 4 (c) shows a film holding member 6 made of thin paper which can be broken by a small force. A hole 6a having the same size as the fixing member 2 and a little larger than the hole 2a is provided at the same position as the hole 2a. An adhesive portion 6b is provided at the same position as the adhesive portion 2d of the fixing member 2. FIG. 4 (d) is FIG. 4 (a)
(C) is a cross-sectional view in which a probe cover is completed by combining the components shown in (c), the infrared transmitting film 1 is placed on the fixing member 2, and the film holding member 6 is further placed thereon.
And the adhesive portion 2d of the fixing member 2 and the adhesive portion 6b of the film holding member 6 are attached with the adhesive 8. That is, the infrared transmitting film 1 is sandwiched between the fixing member 2 and the film holding member 6.

In the probe cover having such a configuration, the portion of the bridge 2c is attached to the probe of the radiation thermometer in the same manner as in the first embodiment, and the outer portion 2b is held and pulled after the attachment in the same manner as in the second embodiment. And the unnecessary outer portion 2b of the fixing member 2 can be removed. At this time, the film holding member 6 is torn and separated, and only the infrared transmitting film 1 and the fixing portion 2e are mounted on the probe side of the radiation thermometer. In addition, as described in the second embodiment, by forming a portion to be gripped on a part of the fixing portion 2e, removal of the probe cover becomes easy.

In this embodiment, the fixing member 2 and the film holding member 6
Although the infrared transmitting film 1 is sandwiched between the above two components, the same effect can be obtained even if the fixing member 2 has twice the size and is folded in two and sandwiched. However, in that case, it is necessary to provide the hole 2a and the bridge 2c at positions symmetrical with respect to the folding line.

[Effect of the invention]

As is clear from the above description, according to the present invention, since the entire portion of the probe cover covering the probe is a thin film, the shape of the probe hardly changes even when the probe cover is attached, and as a result, the shape of the probe is measured. It can be shaped to fit the site. Further, since the probe cover is in a sheet shape before use, it is possible to realize a probe cover which is easy to handle and requires a small storage space.

In addition, when the part where the hole of the fixing member is formed can be cut off, a part that interferes with inserting the probe of the radiation thermometer into the hole can be deleted,
In addition, since a pinch portion for removing the probe cover can be formed, removal becomes very easy.

Further, if the infrared transmitting film is sandwiched between two sheets or one folded sheet of paper, the film does not come into direct contact with the film at the time of handling, which makes handling easier and more hygienic.
