[First Embodiment]
The nasal breath test tool 10 according to the first embodiment will be described with reference to FIGS. 1 to 4.
FIG. 1 is a view showing a usage mode of the nasal breath test tool 10 according to the first embodiment, FIG. 2 is a view of the nasal breath test tool 10 according to the first embodiment as viewed from above, and FIG. 3 is a view. , The nasal breath test tool 10 according to the first embodiment is a view viewed from above the back surface, and FIG. 4 is an exploded view of the nasal breath test tool 10 according to the first embodiment.

The nasal breath test tool 10 according to the first embodiment has a nasal breath mirror 5, a mirror support 11, and a substrate case 20 as main configurations.
The nasal breath mirror 5 has an examination surface 7 to which the nasal breath image of the subject P is attached, and the mirror support 11 supports the nasal breath mirror 5. The substrate case 20 supports an electronic component connected to an imaging unit 2 capable of photographing a nasal breath image attached to the inspection surface 7 of the nasal breath mirror 5. The mirror support 11 corresponds to the first support, and the substrate case 20 corresponds to the second support.

As shown in FIG. 1, when the subject P puts his nose above the examination surface 7 of the nasal speculum 5 and blows his nose, a nasal breath image is formed on the examination surface 7 due to cloudiness of the nasal breath. The nasal breath test tool 10 photographs the nasal breath image with two imaging units 2 arranged on the side of the nasal breath mirror 5, and performs a nasal breath test based on the captured nasal breath images. As the analysis method and the inspection method of the nasal breath image, existing methods as disclosed in the above-mentioned Patent Documents 1 to 3 can be used. The present embodiment does not limit those methods. Further, the nasal breath test tool 10 may only transmit or store the image data acquired from the imaging unit 2 to an external device without performing analysis processing on the nasal breath image.

The nasal breath mirror 5 has a rectangular plate shape with rounded corners, and has a mirror surface to be inspected. The shape of the nasal speculum 5 is not limited as long as it can be placed under the nose of the subject P and a nasal breath image can be formed. For example, the nasal speculum 5 is made of stainless steel, and a semicircular scale and radial lines are engraved on the inspection surface 7. An existing nasal speculum may be used for the nasal speculum 5.

The mirror support 11 as a whole has a shape imitating a hollow apple. The front side of the mirror support 11 has an apple-like exterior as shown in FIG. 2, and the back side of the mirror support 11 is open as shown in FIG.
Specifically, on the front side of the mirror support 11, the exterior of the range visible to the subject P at the time of inspection is a model of an apple having a cut surface 14 after being cut off by about a quarter. ing. This exterior makes the subject P feel familiar and interested, and suppresses the resistance and fear of the subject P to the nasal breath test tool 10.

An opening 13 is provided in the cut surface 14 of the exterior that imitates an apple. The inside (hollow portion) of the mirror support 11 can be visually recognized by the opening 13. In a state where the nasal breath mirror 5 is supported by the mirror support 11, the front end of the nasal breath mirror 5 is arranged at the lower end of the opening 13. As a result, the subject P can form a nasal breath image on the examination surface 7 of the nasal speculum 5 by inserting the nose into the opening 13 as shown in FIG. Further, where the shape of the apple is substantially spherical, the front side of the mirror support 11 is concave toward the back side due to the cut surface 14, so that the subject P can easily insert the nose into the opening 13. It has become. That is, the lower portion of the opening 13 in the cut surface 14 is the exterior surface 15 that is close to the mouth of the subject P at the time of inspection.

The back side of the mirror support 11 is open as shown in FIG. 3, and the support plate 12 provided inside the mirror support 11 is exposed. This makes it easier for the measurer (or examination assistant) E to confirm whether the nasal breath image is properly attached to the nasal breath mirror 5 when the nasal breath mirror 5 is placed on the support plate 12. ..

The support plate 12 is a member provided inside (hollow portion) of the mirror support 11 to support the nasal breath mirror 5. That is, in the first embodiment, the support plate 12 corresponds to the support portion. The nasal speculum 5 is supported on the support plate 12 from the lower surface by being placed on the support plate 12. The support plate 12 has a recess on the support surface (upper surface) having a step corresponding to the thickness of the nasal speculum 5 for fitting the main surface of the nasal speculum 5, and the wall surface extending to the step provides the nasal speculum 5. It may be formed so as to cover the end face of the. According to this recess, it is possible to prevent the nasal breath mirror 5 from being displaced on the support plate 12, and it is possible to shield the end face from the subject P. Since the end face of the nasal speculum 5 can be perceived as thin and sharp, if such an end face is exposed on the side of the subject P who is going to be inspected, the subject, especially the infant P, will be told. Although it may not be possible to perform a normal examination due to a feeling of fear or resistance, the fact that the end face of the nasal breathscope is covered suppresses the fear of the subject P and enables an accurate examination.

In the present embodiment, the support plate 12 supports the entire lower surface of the nasal speculum 5, but may be shaped to support a part thereof. Further, the support structure of the nasal speculum 5 in the mirror support 11 is not limited to a structure that supports the lower surface of the nasal breath mirror 5, and is a structure that can support the nasal breath mirror 5 such as a structure that sandwiches the nasal speculum 5 from the side. All you need is.
The support plate 12 is held by the mirror support 11. The support plate 12 may be integrally molded with the mirror support 11, or may be fixed to the mirror support 11.

As shown in FIG. 4, below the support plate 12 inside the mirror support 11, a storage space 18 capable of accommodating the substrate case 20 and a detachable opening for inserting the substrate case 20 communicating with the accommodation space 18 can be inserted. 16 is provided. The substrate case 20 is inserted into the inside of the mirror support 11 from the attachment / detachment port 16 and is accommodated in the accommodation space 18. In addition, a case support portion 17 is provided below the accommodation space 18, and the case support portion 17 supports the substrate case 20 housed in the accommodation space 18 from below.
The accommodation space 18 is provided on the back side of the exterior surface 15 close to the mouth of the subject P at the time of inspection, and the attachment / detachment opening 16 is also provided on the back side of the exterior surface 15. As a result, it can be said that the exterior surface 15 prevents the substrate case 20 housed in the storage space 18 from coming into contact with the mouth of the subject during the inspection.

The substrate case 20 is a hollow box-shaped body, which is connected to an image pickup unit 2 such as a printed circuit board and accommodates electronic components for processing an image signal output from the image pickup unit 2 and wiring for transmitting the image signal. ing.
Further, the substrate case 20 has two camera support portions 22 on both sides of the box-shaped body. The camera support portion 22 is a tubular body, and supports the image pickup portion 2 inserted in the hollow of the camera support portion 22 while maintaining a predetermined angle of view. It is preferable that the camera support unit 22 covers the image pickup unit 2 and the electronic components and wiring around the image pickup unit 2 as much as possible so as to shield the subject P during the inspection. For example, the camera support portion 22 covers the image pickup unit 2 and the like so that only the lens portion of the image pickup unit 2 is exposed.

The image pickup unit 2 is an image pickup device (camera) formed by an image pickup element, a lens, or the like that converts light captured through a lens into an electric signal. The imaging unit 2 continuously photographs the nasal breath image attached to the surface of the nasal breath mirror 5 for a certain period of time, acquires the nasal breath image, and outputs the image signal. The image pickup unit 2 is realized as, for example, a CCD (Charge Coupled Device) camera. The image pickup unit 2 is fixed to the left and right side portions of the nasal breath mirror 5 by the camera support unit 22. For example, the imaging unit 2 photographs the examination surface 7 of the nasal speculum 5 with an elevation angle of 10 to 20 degrees and obliquely above the front and back.
The imaging unit 2 has a wireless communication function, and may transmit an image signal by wireless communication to the printed circuit board housed in the box-shaped body of the substrate case 20. In this case, there is no need for wiring to connect the image pickup unit 2 and the printed circuit board.

A CPU (Central Processing Unit), a memory, an input / output interface (I / F), a communication unit, and the like are mounted on the printed circuit board housed in the box-shaped body of the board case 20 (see FIG. 9). In addition, a power source (battery or the like) for driving the image pickup unit 2 and these electronic components is also housed. The CPU can perform predetermined image processing and analysis processing on the nasal breath image by reading and executing the program stored in the memory. For example, by synthesizing the image data captured by the two imaging units 2 and performing a predetermined image analysis on the combined image, the shape, area, and time of the nasal breath image, which are important in the diagnosis of nasal breath, are performed. It is possible to acquire information such as the state of physical and spatial changes. Since existing methods such as those disclosed in Patent Documents 1 to 3 described above can be used for such a nasal breath image analysis method and inspection method, a specific description thereof will be omitted. Further, the printed circuit board may only transmit the image data acquired from the image pickup unit 2 to an external device without performing such image analysis.
The present embodiment does not limit any electronic or electrical hardware elements such as the imaging unit 2 and electronic components connected to the imaging unit 2, as well as software elements.

With the above-described configuration, according to the present embodiment, only the mirror support 11 that touches the skin of the subject P at the time of inspection can be cleaned and disinfected by simply removing the substrate case 20, so that the nasal breath inspection tool 10 can be easily and repeatedly used while keeping it clean. Further, it is possible to prevent the electronic components connected to the imaging unit 2 and the imaging unit 2 from being damaged by cleaning or disinfection.

Further, supplementing the above configuration, the cut surface 14 (particularly, both side portions of the opening 13) on the front side of the mirror support 11 extends (erected) above the inspection surface 7 of the nasal breath mirror 5. It can be called a shielding portion that shields both the left and right margins (both the left margin and the right margin) of the examination surface 7 of the nasal speculum 5 from the subject P at the time of inspection. It can also be said that this shielding portion hides the shape of the nasal breath mirror 5 so that it is difficult for the subject P to grasp at the time of the examination.
In the present specification, "shielding from a subject at the time of examination" has a broad meaning of not showing as much as possible to a subject who is undergoing or is about to undergo the examination, and is undergoing or is being examined. It is not limited to the narrow meaning of never showing it to the subject who is going to be examined.
If the left and right edges of the nasal speculum 5 are completely exposed and can be easily seen by the subject P during the examination, the shape of the nasal speculum 5 is the subject P (especially in the case of a child). ) May give fear and resistance and may not be able to be inspected smoothly. However, as in the present embodiment, since the left and right edges of the nasal speculum 5 are completely shielded, it is difficult for the subject P to grasp the shape of the nasal speculum 5, so that the subject P is afraid. It is possible to suppress such problems and perform a smooth and accurate nasal breath test.

Further, in this embodiment, the cut surface 14 is a part of a three-dimensional apple model. It is a part of a model that imitates a familiar real thing called an apple, and by shielding both the left and right edges of the nasal speculum 5 (the shape of the nasal speculum 5), the resistance of the subject P can be further suppressed. it can. However, the shielding portion that shields the left and right peripheral edges of the nasal breath mirror 5 may be a part or all of a three-dimensional model other than the apple.
In addition, in the present embodiment, the cut surface 14 also shields the imaging unit 2 and the camera support unit 22 from the subject P at the time of inspection. That is, the cut surface 14 can be called a shielding portion that further shields a part or all of the imaging unit 2 from the subject P at the time of inspection. As a result, the fear and resistance given to the subject P by the imaging unit 2 can be suppressed, and a smooth nasal breath examination becomes possible.

[Second Embodiment]
Next, the nasal breath test tool 30 according to the second embodiment will be described with reference to FIGS. 5 to 7.
FIG. 5 is a perspective view of the nasal breath test tool 30 according to the second embodiment, FIG. 6 is a view of the nasal breath test tool 30 according to the second embodiment viewed from above the front, and FIG. 7 is a second. It is an exploded view of the nasal breath inspection tool 30 which concerns on embodiment.

Similar to the first embodiment, the nasal breath test tool 30 according to the second embodiment has a nasal breath mirror 5, a mirror support 31, and a substrate case 40 as main configurations.
The nasal breath mirror 5 is the same as that of the first embodiment. The mirror support 31 supports the nasal breath mirror 5, and the substrate case 40 supports electronic components connected to the imaging unit 2. That is, the mirror support 31 corresponds to the first support, and the substrate case 40 corresponds to the second support. The imaging unit 2 is the same as in the first embodiment.
Similarly to the first embodiment, the nasal breath inspection tool 30 according to the second embodiment also has two imaging units 2 arranged on the side of the nasal breath mirror 5 to display a nasal breath image attached to the inspection surface 7 of the nasal speculum 5. A nasal breath test is performed based on the photographed nasal breath image. As the analysis method and the inspection method of the nasal breath image, existing methods as disclosed in the above-mentioned Patent Documents 1 to 3 can be used. The present embodiment does not limit those methods.

The mirror support 31 is a hollow box-shaped body whose back surface is open as a whole.
As shown in FIG. 6, the front surface of the mirror support 31 has a concave curved surface 34 recessed toward the back surface side, and the concave curved surface 34 has rounded corners on the left and right sides. As described above, since the front surface of the mirror support 31 has a curved surface shape as a whole, the resistance and fear of the subject P to the tool can be alleviated. Further, the concave curved surface 34 is an exterior surface close to the mouth of the subject P at the time of inspection. The concave curved surface 34 makes it easier for the subject P to place his nose above the examination surface 7 of the nasal breath mirror 5.

The upper surface of the mirror support 31 is composed of a support surface (upper surface) of the support plate 32 that supports the nasal breath mirror 5 and a partial upper surface 33 that is higher than the support surface of the support plate 32 by the thickness of the nasal speculum 5. Therefore, in the second embodiment, the support plate 32 corresponds to the support portion.
The substantially rear half of the upper surface of the mirror support 31 in the front-rear direction is formed only from the support plate 32. The substantially rear halves of the left and right side surfaces of the mirror support 31 are opened so that a part of the camera support portion 42 can pass through when the substrate case 40 is mounted on the mirror support 31. The partial upper surface 33 exists around the support surface of the support plate 32 which is substantially the front half of the upper surface of the mirror support 31. The end surface of the nasal speculum 5 on the subject side is covered by the wall surface extending in the step between the partial upper surface 33 and the support surface (upper surface) of the support plate 32. The wall surface shields the end surface of the nasal speculum 5 from the subject P at the time of examination while preventing the nasal speculum 5 from being displaced. By covering the end face of the nasal speculum 5 in this way, the resistance of the subject P can be suppressed.

In the present embodiment, the support plate 32 supports the entire lower surface of the nasal speculum 5, but may be shaped to support a part thereof. In this case, the upper surface of the mirror support 31 may be open. Further, the support structure of the nasal speculum 5 in the mirror support 31 is not limited to a structure that supports the lower surface of the nasal breath mirror 5, and a structure that can support the nasal breath mirror 5 such as a structure that sandwiches the nasal speculum 5 from the side. All you need is.

The back side of the mirror support 31 is open as shown in FIG. As shown in FIG. 7, a storage space 36 capable of accommodating the substrate case 40 is provided inside the mirror support 31, and the back side of the mirror support 31 communicates with the accommodation space 36. An attachment / detachment port 37 into which the substrate case 40 can be inserted is provided. The substrate case 40 is inserted into the inside of the mirror support 31 from the attachment / detachment port 37, and is accommodated in the accommodation space 36.
Further, the accommodation space 36 is provided on the back side of the concave curved surface 34 (exterior surface) close to the mouth of the subject P at the time of inspection, and the attachment / detachment opening 37 is also provided on the back side of the concave curved surface 34. There is. As a result, it can be said that the concave curved surface 34 (exterior surface) prevents the substrate case 40 housed in the storage space 36 from coming into contact with the mouth of the subject P during the inspection.

The substrate case 40 is a hollow box-shaped body, which is connected to an image pickup unit 2 such as a printed circuit board and accommodates electronic components for processing an image signal output from the image pickup unit 2 and wiring for transmitting the image signal. ing.
Further, the substrate case 40 has two camera support portions 42 extending (standing) above the inspection surface 7 of the nasal speculum 5 from both side surfaces of the box-shaped body, and the box shape thereof. It has two model bodies 44 extending (standing) above the inspection surface 7 from the back surface of the body.

The camera support portion 42 and the model body 44 have a shape imitating a tulip, and a portion corresponding to a tulip stem (hereinafter, may be referred to as a stem simulation portion) is the posterior margin of the nasal breath mirror 5. It extends further upward from the part and both left and right margins, and a part corresponding to a tulip flower (hereinafter, may be referred to as a flower simulation part) is further provided above the stem simulation part. .. Then, in a plan view, each flower simulation portion is arranged so as to partially cover the examination surface 7 of the nasal breath mirror 5 placed on the support plate 32. As a result, at least a part of the left and right edges of the examination surface 7 of the nasal breathscope 5 is shielded from the subject P at the time of examination by at least the flower simulation part of the camera support portion 42. Therefore, the camera support portion 42 is extended (erected) above the inspection surface 7 of the nasal speculum 5, and at the time of the inspection, at least the left and right side edges of the inspection surface 7 of the nasal speculum 5 from the subject P. It can be called a shielding part that shields a part. It can also be said that this shielding portion hides the shape of the nasal breath mirror 5 so that it is difficult for the subject P to grasp at the time of the examination. As a result, since at least a part of the left and right margins of the nasal speculum 5 is shielded, it is difficult to grasp the shape of the nasal speculum 5 as compared with the case where all of them are exposed. It is possible to suppress the mind and, by extension, perform a nasal breath test smoothly and accurately.

Furthermore, as shown in FIG. 6, recesses are formed in the stem simulation sites of the camera support portion 42 and the model body 44, and both the left and right sides of the nasal breath mirror 5 mounted on the support plate 32. A part of the edge portion and the rear edge portion is inserted into the recess.
From this, both the camera support portion 42 can be called a shielding portion. In addition, the model body 44 can be called a shielding portion that shields at least a part of the rear edge portion of the inspection surface 7 of the nasal speculum 5 from the subject P at the time of inspection. Due to such a structure, according to the present embodiment, not only at least a part of the left and right side edges of the examination surface 7 of the nasal breathscope 5 but also at least a part of the rear edge part is from the subject P at the time of the examination. Since it is shielded, the resistance of the subject P can be further alleviated.
Further, it is possible to prevent the nasal speculum 5 from coming off the support plate 32 upward due to the recesses of the stalk simulation portion of the camera support portion 42 and the model body 44.

Further, in the present embodiment, the camera support portion 42 and the model body 44 are three-dimensional tulip models. That is, the resistance of the subject P is reduced by shielding at least a part of the left and right edges of the nasal speculum 5 and at least a part of the rear edge with a model that imitates a familiar real object called a tulip. It can be further suppressed. However, the shielding portion that shields at least a part of the left and right side edges of the nasal speculum 5 and at least a part of the rear edge portion may be a part or all of a three-dimensional model other than the tulip.

The camera support unit 42 accommodates the image pickup unit 2 inside the flower simulation portion. The flower simulation portion of the camera support portion 42 is provided with an opening for arranging the lens portion of the image pickup unit 2. As a result, the image pickup unit 2 is held inside the flower simulation portion of the camera support portion 42 while maintaining a predetermined angle of view, and adheres to the inspection surface 7 through the opening of the flower simulation portion. Take a nasal breath image.

Further, the stem simulation portion of the camera support portion 42 also has a hollow tubular shape, and it is preferable that the hollow, the hollow of the flower simulation portion, and the hollow of the box-shaped body of the substrate case 40 communicate with each other. As a result, the wiring that connects the image pickup unit 2 housed in the flower simulation part of the camera support unit 42 and the printed circuit board housed in the box-shaped body of the substrate case 40 is provided inside the camera support unit 42 together with the image pickup unit 2. Can be placed.
As a result, the imaging unit 2 and the electronic components and wiring around the imaging unit 2 can be shielded from the subject P at the time of inspection, so that the resistance given to the subject P by the imaging unit 2 and the like can be suppressed. it can. Therefore, the camera support portion 42 can be called a shielding portion that further shields a part or all of the imaging unit 2 from the subject P at the time of inspection. When the image pickup unit 2 and the printed circuit board communicate wirelessly, such a structure may not be necessary.
Also in this embodiment, there are no restrictions on electronic or electrical hardware elements such as the imaging unit 2 and electronic components connected to the imaging unit 2, as well as software elements.

With the above-described configuration, also in the present embodiment, as in the first embodiment, only the mirror support 31 that touches the skin of the subject P at the time of inspection is cleaned and disinfected by simply removing the substrate case 40. Therefore, the nasal breath test tool 30 can be easily and repeatedly used while being kept clean. Further, it is possible to prevent the electronic components connected to the imaging unit 2 and the imaging unit 2 from being damaged by cleaning or disinfection.

[Modification example]
The first and second embodiments described above are examples of nasal breath test tools, respectively. The nasal breath test tool is not limited to the above-described configuration, and can be deformed without departing from the spirit of the present invention.

For example, the nasal breath test tool 10 or 30 supports a first support capable of supporting the nasal breath plate and an electronic component connected to an imaging unit arranged so that a nasal breath image attached to the inspection surface of the nasal breath plate can be photographed. It suffices that the second support to be obtained is provided, and the first support and the second support are detachably formed from each other.
Here, the "nasal breath plate" means a plate-shaped member having an inspection surface to which a nasal breath image is attached by nasal breath, and the nasal breath image attached to the inspection surface can be photographed by the imaging unit 2. Therefore, the nasal breath plate does not have to have a mirror surface to be inspected like the nasal breath mirror 5 described above.
Further, the "electronic component connected to the imaging unit" is not limited to only the electronic component physically connected to the imaging unit by wiring or the like, and the image signal output from the imaging unit by some communication such as wireless communication is used. It may be a receivable electronic component.
With the above configuration, simply removing the second support from the first support will clean and disinfect only the first support, which is likely to hit the subject's skin during the examination. Can be done. That is, in the nasal breath test tool 10 or 30, it is easy to clean the portion of the nasal breath test tool 10 or 30 that is close to or comes into contact with the subject's mouth during the test. As a result, the nasal breath test tool can be repeatedly used for a large number of subjects while keeping it clean, and it is possible to prevent the electronic components connected to the imaging unit from being damaged by cleaning and disinfection. That is, an easy-to-use nasal breath test tool can be realized by the above-described configuration.

Further supplementing, the nasal breath test tool 10 or 30 does not have to have the nasal breath plate, the imaging unit, and the electronic components connected to the imaging unit, and is (possibly) the first to support the nasal breath plate. It suffices to have a support and a second support (which can support) for supporting the electronic component. Even with such a configuration, the nasal breath test tool 10 or 30 can be used for practice before the actual nasal breath test.
By providing the subject with the nasal breath test tool 10 or 30 having such a configuration before the nasal breath test, the subject can be accustomed to the nasal breath test tool 10 or 30. Even in this case, the nasal breath test tool 10 or 30 can be repeatedly used in a clean state by cleaning only the first support.

Further, the nasal breath test tool 10 or 30 may be a simple cover of a nasal breath plate (nasal breath mirror 5) that does not have an imaging unit, an electronic component connected to the imaging unit, or a second support. In this case, the nasal breath test tool 10 or 30 has a support portion that can support the nasal breath plate and extends above the inspection surface of the nasal breath plate, and is extended from the subject to the left and right sides of the inspection surface at the time of inspection. It suffices to have a shielding portion that shields at least a part of the edge portion. This shielding portion may also be described as shielding a part or all of the inspection surface of the nasal breath plate so that it is difficult for the subject to grasp the shape of the inspection surface at the time of inspection.
With such a configuration, at least a part of the left and right edges of the examination surface of the nasal breath plate is shielded from the subject who is going to be examined, so that the shape of the nasal breath plate is completely exposed. Compared with the case where the examination is performed while the patient is in the state (for example, only with a nasal breath microscope), the resistance and fear of the subject can be alleviated, and as a result, a smooth nasal breath examination becomes possible.

Further, in the first and second embodiments, the shielding portion (cut surface 14 and camera support portion 42) was a part or all of the three-dimensional model imitating an apple or tulip, but other three-dimensional models. It may be a part or all of. This three-dimensional model may be a fictitious person or object such as an anime or cartoon character or tool, in addition to a person or object existing in the real world. Of course, the shielding portion does not have to be a part or all of the three-dimensional model.

FIG. 8 is a view of the nasal breath test tool 50 according to the first modification as viewed from above the front.
The nasal breath test tool 50 according to the first modification also supports the mirror support 51 including the support portion capable of supporting the nasal breath mirror 5 and the electronic component connected to the imaging unit 2 as in each of the above-described embodiments. It has a possible substrate case 60 (not shown).
The mirror support 51 is a hollow box-shaped body, and the substrate case 60 is detachably housed inside the mirror support 51. A recess (corresponding to the above-mentioned support portion) is formed on the upper surface of the mirror support 51, and the nasal breath mirror 5 is placed in the recess.

In the first modification, the camera support portion 62 is formed separately from the substrate case 60. The camera support portion 62 has an arch shape straddling the nasal breath mirror 5 in the left-right direction, and is detachably attached to the upper surface of the mirror support 51 at the end of the arch shape. When mounted on the upper surface of the mirror support 51, the camera support portion 62 supports the two imaging portions 2 in the predetermined orientation and position as described above, and at both ends thereof, the inspection surface of the nasal breath mirror 5. It covers a part of both left and right side edges of 7. For this reason, the nasal breath test tool 50 according to the first modification has a support portion capable of supporting the nasal breath plate to which the nasal breath image of the subject is attached and an extension above the inspection surface of the nasal breath plate. It can also be provided with a shielding portion (corresponding to the camera support portion 62) that shields the subject from at least a part of the left and right side edges of the inspection surface at the time of inspection.
As described above, even in the first modification, since at least a part of the left and right side edges of the inspection surface 7 of the nasal breath microscope 5 is shielded from the subject P at the time of inspection, the same effect as described above can be obtained. Can be done.

The nasal breath test tool 10, 30, or 50 described above may further include an aroma emitting portion that emits aroma. According to this, the fragrance gives the subject P a feeling of comfort and a sense of security, and it is possible to suppress a feeling of resistance and fear of the nasal breath test.
The fragrance emitting part may be provided in a form in which the subject P can perceive the fragrance at the time of inspection. A member having a fragrance on a portion close to the subject P at the time of inspection, for example, a cut surface 14, an exterior surface 15, a concave curved surface 34, a camera support portion 42, or a model body 44 may be used. The agent may be applied. In addition to this, a container-shaped member for containing an air freshener may be provided.
Further, the type of fragrance is not limited as long as it has a so-called good odor that gives the subject P a sense of comfort and security. That is, the specific form of the aroma emitting portion is not limited.

FIG. 9 is a diagram conceptually showing the electrical configuration of the nasal breath test tool according to the second modification.
As shown in FIG. 9, the nasal breath test tool may further have a detection unit 75 for detecting the state of the device and a notification unit 76 for notifying the state detected by the detection unit 75.

The detection unit 75 is a sensor provided on the nasal breath test tool itself. The state of the tool detected by the detection unit 75 may be any state as long as it is the state of the nasal breath test tool. For example, the detection unit 75 can detect the inclination of the nasal breath inspection tool (nasal breath mirror 5 or the like), whether or not the image is being taken by the nasal breath mirror 5, the installation condition of the nasal breath mirror 5, the orientation of the imaging unit 2, and the like. Specifically, the inclination can be detected by an acceleration sensor, an inclination sensor, or the like, and the installation condition of the nasal breath mirror 5 can be detected by a contact sensor, a pressure sensor, or the like. When the detection unit 75 is realized as a sensor, the sensor signal from the detection unit 75 may be received by the input / output interface (I / F) 72 mounted on the printed circuit board and processed by the CPU 70. ..
Further, the detection unit 75 may be realized as a software element. For example, the detection unit 75 analyzes the image captured by the image pickup unit 2 by the image analysis process realized by executing the program stored in the memory 71 by the CPU 70, so that the orientation of the image pickup unit 2 and the like can be determined. Can be detected.

The notification unit 76 may be a display device that displays the detected device status, or may be a voice output device that outputs the device status by voice. The specific notification method by the notification unit 76 is not limited. The display device may be an LCD (Liquid Crystal Display), a CRT (Cathode Ray Tube) display, or a light emitting element such as an LED (Light Emitting Diode). When the notification unit 76 is realized by an LED, the equipment state can be displayed by changing the emission color depending on whether or not shooting is in progress, or changing the emission color depending on whether or not the inclination is larger than a predetermined angle.
When the notification unit 76 is realized as a display device, the notification unit 76 may be installed at a position visible to a person other than the subject P, such as the measurer E, who assists the inspection.

According to the second modification, the state of the tool is automatically detected and the state is notified, so that the measurer E or the like can easily grasp the state of the nasal breath test tool, and by extension, the accuracy of the nasal breath test. The sex can be improved.
