Description

  The present invention relates to a breath test apparatus. More specifically, the present invention relates to a breath test apparatus capable of detecting an influenza virus or the like contained in a breath exhaled by a person at an early stage of infection.

Some infectious pathogens such as influenza virus and Mycobacterium tuberculosis are contained in the breathing and splashing of people and organisms infected with these pathogens, and are scattered in the air and infect those who inhale them. .
In particular, there are pathogens that are scattered in the air as droplets, and there are those that retain their pathogenicity even after the water evaporates and becomes droplet nuclei, and such pathogens float and move alone for a long time, It becomes easy to cause infection (air infection) to others.

  Airborne pathogens can be easily spread by the movement of infected people and the range of infection is expanded, so it is necessary to detect infected people and isolate them as soon as possible. .

In order to detect such an infected person, an apparatus for examining the breath of a person or a living organism has been developed (Patent Document 1).
Patent Document 1 discloses a subject state determination device that determines the state of a subject by analyzing components contained in the breath that the subject breathed in, and is also used to check for viruses and bacteria contained in the subject's breath. It is disclosed that it can be used.

However, in the subject state determination device of Patent Document 1, even if the component contained in the breath inhaled by the subject is analyzed and the component is inspected, there is nothing about the processing of the exhaled breath injected into the device. There is a possibility that exhaled air is discharged outside as it is without being touched.
Then, if the person (subject) who performed the test is infected with the pathogen, the infection of the subject can be grasped, but at that time, the pathogen contained in the exhaled breath from the subject is scattered around. There is a possibility that the inspector may become infected with the pathogen.
Moreover, in the subject state determination device of Patent Document 1, if the inspector takes measures against infection, the inspector can be prevented from being infected with a pathogen, but for example, when the inspection is performed at an airport or the like. Even if the inspector is not infected, there is a possibility of infection to other users.

Furthermore, in order to prevent the spread of new influenza at airports and the like, it has been examined whether or not it is infected with new influenza by an infrared thermography system or the like. In this inspection, an infrared thermography system is installed near the immigration inspection at the airport, and the temperature of the immigrants is checked. If a fever of 38 degrees or more is observed, it is assumed that the person is infected with a new influenza. Have been inspected closely.
However, with this method, even if there is a person who is infected with the new influenza, if the person does not have a fever of 38 degrees or more, the infected person cannot be grasped. Then, an infected person who does not have fever may enter the country as it is and then develop at home or at a hotel, and it is difficult to prevent the spread of infection.
In addition, it is not possible to grasp the infection to a specific pathogen, such as those who have fever due to other diseases and are subject to re-examination as infected persons.

JP 2009-229307 A

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a breath test apparatus that can safely and accurately check a virus or the like contained in a breath exhaled by an infected person, and can grasp an initial infection. And

A breath test apparatus according to a first aspect of the present invention is a breath test apparatus for detecting a pathogen contained in a breath, wherein the breath suction section introduces a subject's breath, and a discharge section discharges air introduced from the breath suction section. A connection passage communicating between the exhalation breathing portion and the discharge portion, a bypass passage bypassing between the connection passage and the discharge portion, and an inspection means for inspecting air passing through the bypass passage And a detoxifying means for detoxifying pathogens in the exhaled breath passing through the connection passage.
In the breath test apparatus according to a second aspect of the present invention, in the first aspect, the connection passage is a hollow passage formed of a material that transmits ultraviolet rays, and the harmless means irradiates the ultraviolet rays toward the connection passage. It is the ultraviolet irradiation means arrange | positioned so that it may be characterized by the above-mentioned.
The breath test apparatus according to a third aspect of the present invention is characterized in that, in the first or second aspect, the air test section is a device that measures particles present in the air.

According to the first invention, if the subject blows into the exhalation suction part, the exhalation is introduced into the connection passage by the exhalation suction part. The introduced exhaled breath fills the temporary connection passage, then flows through the connection passage toward the discharge portion, and is discharged from the discharge portion. At this time, a part of the exhaled air flows from the connection passage through the bypass passage to the discharge portion. The exhaled breath passing through the bypass passage is inspected by the inspection means while passing through the bypass passage. For example, the presence or absence of a pathogen is examined. Therefore, since the breath exhaled by a person can be examined, an infected person infected with a pathogen can be found. Moreover, since the exhaled breath that passes through the connecting passage is purified by the detoxifying means, even if pathogens exist in the exhaled breath that flows directly from the connecting passage to the discharge portion and the exhaled flow that passes through the bypass passage to the discharge portion, These pathogens are detoxified. Therefore, the air exhausted from the apparatus can also prevent infection to an inspector and surrounding people.
According to the second invention, the pathogen contained in the air can be rendered harmless simply by irradiating the air in the connection passage with ultraviolet rays by the ultraviolet irradiation means. Moreover, since the connection passage is made of a material that transmits ultraviolet rays, the air in the connection passage can be made harmless even if the connection passage is kept airtight from the outside. Therefore, when the air in the connection passage is rendered harmless, it is possible to prevent the exhalation including pathogens from leaking to the outside.
According to the third invention, if particles contained in exhaled breath are measured, it is checked whether or not the virus is infected even at the early stage of infection by comparing the measurement result of a healthy person with the measurement result of an infected person. can do.

FIG. 4D is a view taken in the direction of arrows C, and (D) is a view taken in the direction of arrows D in FIG.

Next, an embodiment of the present invention will be described with reference to the drawings.
The breath test apparatus of the present invention is a device for detecting a pathogen contained in a person's breath, and can detect infection even in a patient at an early stage of infection. This is characterized in that it can be prevented.

(Exhalation test apparatus 1 of this embodiment)
In FIG. 1 and FIG. 2, the code | symbol 2 has shown the case of the breath test | inspection apparatus 1 of this embodiment. The case 2 is formed in a hollow box shape. The inside of the case 2 is divided into an upper space and a lower space by a partition plate 2a, and an upper space 2h hermetically sealed from the outside is provided above the partition plate 2a.

  In FIG. 3, the upper space 2 h of the case 2 is provided with a connection passage 10 and an ultraviolet lamp 30 that is a harmless means.

  The connection passage 10 is formed of a hollow cylindrical member made of transparent acrylic, and the tip (left end in FIGS. 1 and 2) and the base end (right end in FIGS. 1 and 2) are the case. 2 are held on the wall of the front (left side in FIGS. 1 and 2) and the wall on the back (right side in FIGS. 1 and 2), and their end faces are exposed from the front and back. That is, in the case 2, a passage that communicates between the front surface and the back surface is formed by the connection passage 10.

As shown in FIG. 3, an ultraviolet lamp 30, which is a harmless means, is provided on the side of the connection passage 10. The ultraviolet lamp 30 is disposed so as to irradiate ultraviolet rays toward the connection passage 10.
The number of the ultraviolet lamps 30 provided is not particularly limited, and a pair of ultraviolet lamps 30 and 30 are arranged so as to face each other with the connection passage 10 therebetween, or arranged so as to surround the connection passage 10. Also good. And if the installation number of the ultraviolet lamp 30 is increased, the advantage that the bactericidal effect of the pathogen in the connection channel | path 10 can be heightened is acquired.

  A bypass passage 21 that communicates between the connection passage 10 and the back surface of the case 2 is provided in a lower space in the case 2. The bypass passage 21 is provided with an air inspection unit 22 that detects influenza viruses, bacteria, and the like contained in the air. The air inspection unit 22 is an inspection device having a function of inhaling air, such as an aerosol monitor (manufactured by TSI), and a function of inspecting the inhaled air. The air inside is sucked and the air after the inspection is discharged to the back surface of the case 2 through the bypass passage 21.

And the exhalation suction part 5 which the test subject inspects blows exhalation is provided in the front-end | tip of the connection channel | path 10, ie, the front of case 2. As shown in FIG. The exhalation suction part 5 is a member having a tip part 5 a formed in a substantially cone shape with its tip widened, and its base end is connected to the tip of the connection passage 10.
On the other hand, a discharge portion 6 is provided on the back surface of the case 2 so as to cover the base end of the connection passage 10 and the opening on the back side of the case 2 in the bypass passage 21. The discharge portion 6 is airtightly attached to the back surface of the case 2, and the air discharged from the proximal end of the connection passage 10 and the bypass passage 21 is discharged to the outside only from the discharge port 6 h provided on the back surface. It is provided so that.

  Since the configuration is as described above, air is introduced into the connection passage 10 if the subject to be inspected blows into the exhalation suction part 5. Then, when a pathogen is contained in the introduced air, the pathogen in the air is rendered harmless in the connection passage 10 by the ultraviolet rays emitted from the ultraviolet lamp 30. Then, the air in which the pathogen is rendered harmless is discharged into the discharge unit 6 from the proximal end of the connection passage 10 and discharged to the outside from the discharge port 6h of the discharge unit 6.

  On the other hand, a part of the air in the connection passage 10 is sucked into the air inspection unit 22 through the bypass passage 21. Then, the pathogen in the air sucked by the air inspection unit 22 (detoxified pathogen) can be detected. That is, since a pathogen such as a virus contained in a person's breath can be examined, an infected person infected with the pathogen can be found.

  The air sucked into the air inspection unit 22 is also discharged into the discharge unit 6 through the bypass passage 21 and discharged to the outside from the discharge port 6h of the discharge unit 6. This air is already harmless in the connection passage 10. It has become.

  Therefore, all of the air that enters the connection passage 10 and is discharged to the outside from the discharge port 6h of the discharge portion 6 is made harmless by the ultraviolet lamp 30 regardless of the route. Therefore, even if the examined subject is infected with the pathogen, the air discharged from the apparatus can prevent the inspector, surrounding people, and the like from being infected with the pathogen.

In the above example, the case where the member 5a formed in a substantially cone shape is used as the exhalation suction part 5, but the independent exhalation suction part 5 as described above may not be provided. In that case, what is necessary is just to let the front-end | tip of the connection channel | path 10 be the exhalation suction part said to a claim.
Further, a filter f that captures mist such as saliva contained in exhaled breath may be provided at the tip of the exhaled breath sucking portion 5 (the tip of the connection passage 10 when the exhaled breath sucking portion 5 is not provided). In this case, when a person blows, saliva and the like can enter the connection passage 10 and prevent the connection passage 10 from being soiled, and saliva and the like can enter the air test unit 22. It is possible to prevent an inspection error from occurring.

Further, as in the above example, when the air in the connection passage 10 is purified by the ultraviolet lamp 30, the air directly discharged from the connection passage 10 is also the air discharged from the bypass passage 21 through the air inspection unit 22. Both are purified and the pathogen is detoxified. Therefore, the air may be directly discharged from the connection passage 10 and the bypass passage 21 to the outside without providing the discharge portion 6.
However, if the discharge unit 6 is provided, a HEPA filter or the like can be provided inside or inside thereof. Then, even if a pathogen that could not be detoxified by the ultraviolet lamp 30 is discharged from the connection passage 10 and the bypass passage 21, it can be captured by the HEPA filter.

  Note that the air in the connection passage 10 stays in the connection passage 10 to some extent, but in order to improve the accuracy of the inspection in the air inspection unit 22, the air is stored in the connection passage 10 for a predetermined time. You may add a function that can For example, an opening / closing valve or the like that can cut off communication between the inside of the discharge unit 6 and the outside is provided at the discharge port 6 h of the discharge unit 6. Then, if the on-off valve is closed, air can be stored in the connection passage 10, and if the on-off valve is opened, the inside of the connection passage 10 is communicated with the outside, and the air is connected to the outside of the connection passage 10. Can be discharged.

  Moreover, in the example mentioned above, the air test | inspection part 22 has a function which attracts | sucks air, The air is attracted | sucked in the connection channel | path 10 only by this suction force. However, when a HEPA filter or the like is provided, the air resistance increases, and there is a possibility that the air cannot be sufficiently sucked only by the suction force of the air inspection unit 22. Therefore, when a HEPA filter or the like is provided, it is preferable to separately provide a suction means for sucking air such as a blower. If the pathogenic agent can be completely captured by the aerobic resistance placed and sucked, a HEPA filter may be arranged in the discharge part 6 without using the ultraviolet lamp 30 as a detoxifying means.

  Furthermore, as long as the pathogen can be completely captured by a HEPA filter or the like provided inside the discharge unit 6, a HEPA filter may be disposed in the discharge unit 6 without using the ultraviolet lamp 30 as detoxifying means.

  Further, the HEPA filter or the like is not necessarily arranged in the discharge unit 6, and the air discharged to the outside from the discharge port 6 h must pass through the HEPA filter or the like and be discharged to the outside. Alternatively, it may be provided outside the discharge unit 6.

(About the air inspection unit 22)
As described above, the air inspection unit 22 is not particularly limited as long as it has a function of sucking air and inspecting the air.
However, a device capable of measuring the weight of particles in the air, specifically, the weight for each particle diameter, is preferable as a device for determining the presence or absence of a pathogen in detecting the initial infection.
The reason is as follows.

It takes about 8 to 12 hours until a virus that infects humans is replicated (until a cell is infected and a progeny virus is made), but it is 100 to 1000 from one virus in one replication. A degree of progeny virus is formed. One day after the infection, the virus will increase to about 1 million. As the number of viruses increases, the number of viruses contained in exhaled breath increases, so the number of viruses contained in exhaled breath increases.
If the virus contained in the exhalation increases, the weight of the particle of the particle size to which the virus belongs in the exhalation increases compared to the case where the virus is not infected. I can grasp it. Moreover, even if a person is infected but has not developed a virus, as described above, the number of viruses in the body increases in one day, so even if only one day has passed since the infection, it is included in exhalation. In the case of particles, the weight of the particle size to which the virus belongs is greatly increased.
Therefore, if the weight for each particle size of the particles contained in the exhaled breath is measured by a device capable of measuring the weight for each particle size, each particle of the particles in the breath of an uninfected person (that is, the breath of a healthy person) By comparing with the weight for each diameter, it is possible to inspect whether or not the virus is infected even at the early stage of infection.

For example, in the above-described aerosol monitor (manufactured by TSI), the weight of each set particle size of 1, 2.5, 4, 10 μm and the weight of all particles in the range of the measured particle size of 0.1 to 15 μm is 3.0 L. Per minute. In the case of influenza viruses, birds, humans, and pigs are basically the same shape and size, and the size (diameter) is about 0.1 μm. And a cell membrane of a host cell called an envelope. Some viruses immediately after separation have a string shape of about 1 to 2 μm in length (thickness is about 0.1 μm). Then, by measuring the weight (mg / m ³ ) with a particle size of 1.25 μm with an aerosol monitor, whether or not it is infected with influenza virus is compared with the weight in the breath of a person who is not infected with the virus. Can be grasped.

  In addition, as the air test | inspection part 22, the apparatus which can measure the number of particles in air, specifically, the number of particles for every particle diameter, can also be used. Even with such an apparatus, substantially the same effect (detection of initial infection, etc.) can be obtained for the same reason as the apparatus for measuring the weight of particles as described above.

(About connection passage 10)
Next, the connection passage 10 will be described in detail.

  As shown in FIGS. 1 and 2, the case 2 is formed with through holes a and b that communicate between the inside of the upper space 2 h and the outside on the front and back surfaces thereof. The through holes a and b are formed so that the inner diameter of the through hole b provided on the back side is smaller than the inner diameter of the through hole a provided on the front side.

On the other hand, the connection passage 10 is a hollow cylindrical member, and is formed such that its axial length is substantially the same as the depth of the case 2 (the length in the left-right direction in FIGS. 1 and 2). ing. The connection passage 10 is formed so that its outer diameter is the same as or slightly smaller than the inner diameter of the through hole a.
Further, the connection passage 10 is closed at the base end, and communicates with the outside by a mounting tubular portion 10a that is thinner than the outer diameter of the main body of the connection passage 10. The mounting tubular portion 10a is formed to be the same as or slightly smaller than the inner diameter of the through hole b.

Since the connecting passage 10 has the shape as described above, the connecting passage 10 can be inserted into the through hole a from the front of the case 2 from the base end thereof. Then, in a state where the connection passage 10 is inserted into the through hole a, the connection passage 10 can be disposed in the upper space 2 h of the case 2 by inserting the mounting tubular portion 10 a into the through hole b.
That is, the connection passage 10 is mounted in the upper space 2h of the case 2 in a state where the mounting cylindrical portion 10a at the base end is held in the through hole b and the tip is held in the through hole a. Can do it.

  If the connection passage 10 has the shape as described above, the connection passage 10 can be replaced simply by inserting or removing it from the through hole a of the case 2. Then, even if the connection passage 10 is soiled by using the breath test apparatus 1 for a long time and the inspection accuracy is lowered, the connection passage 10 can be easily replaced, so that the inspection accuracy can be easily recovered.

  In addition, the cylindrical part 10a for attachment and the through-hole b do not necessarily need to have the center axis | shaft coaxial with the center axis | shaft of the connection channel | path 10, or the center axis | shaft of the through-hole a. Specifically, as shown in FIG. 1, the mounting tubular portion 10 a and the through hole b may be offset from the central axis of the connection passage 10 and the central axis of the through hole a. With such a configuration, the connection passage 10 can be prevented from rotating around its central axis in a state where the connection passage 10 is mounted in the upper space 2h. And when employ | adopting such a structure, it cannot be overemphasized that it is set as the structure which can insert the cylindrical part 10a for attachment in the through-hole b in the state which inserted the connection channel | path 10 in the through-hole a. That is, the mounting cylindrical portion 10a and the through hole b have the same offset amount of the mounting cylindrical portion 10a with respect to the central axis of the connection passage 10 and the through hole b offset amount with respect to the central axis of the through hole a. Is provided.

  Moreover, it is preferable that the sealing material which airtightly seals the clearance gap between both is attached between the inner surface of the through-holes a and b and the outer surface of the edge part of the connection channel | path 10, respectively. For example, if the gap between the two is hermetically sealed with an O-ring or a silicone-based solvent-free type (liquid gasket) or the like, even if air flowing in the connection passage 10 leaks into the upper space 2h, the air flows from the upper space 2h to the outside. To prevent leakage.

(About bypass passage 21)
A bypass passage 21 for sucking air from the connection passage 10 is inserted into one end thereof, that is, at an end portion on the connection passage 10 side, and a suction pipe 21a provided in the connection passage 10 and the suction pipe 21a. Connecting pipe 21b.

The connecting passage 10 is provided with a through hole 10s that penetrates between the inner surface and the outer surface in the radial direction, and the suction pipe 21a is inserted in the through hole 10s and fixed in an airtight manner. Yes.
On the other hand, the partition plate 2a of the case 2 is formed with a through hole h that communicates between the upper space 2h and the lower space. The through hole h is formed so that its inner diameter is substantially equal to the inner diameter of the suction pipe 21a.
Then, one end of the connection pipe 21b is inserted into the through hole h and fixed in an airtight manner. The other end of the connection pipe 21b is connected to the supply port of the air test unit 22 by a tubular member 21c such as a tube.

  If the connection passage 10 is arranged in the upper space 2h of the case 2 and is positioned and fixed so that the through hole 10s is aligned with the through hole h of the partition plate 2a, the suction pipe is formed. Since the connection passage 10 and the air inspection unit 22 are communicated with each other through the inside of the 21a, the connection pipe 21b, and the inside of the tubular member 21c, the air in the connection passage 10 can be sucked by the air inspection unit 22.

  When the mounting cylindrical portion 10a and the through hole b are offset from the central axis of the connection passage 10 and the central axis of the through hole a, the mounting cylindrical portion 10a is inserted into the through hole b. As a result, the rotation of the connection passage 10 is fixed. Therefore, it goes without saying that the through-hole 10s of the connection passage 10 and the through-hole h of the partition plate 2a are formed so as to be combined with each other in a state where the mounting tubular portion 10a is inserted into the through-hole b. Absent.

  Moreover, the airtightness between the through hole 10s of the connection passage 10 and the through hole h of the partition plate 2a can be maintained by, for example, a method of arranging a seal member between the two. However, if the connecting pipe 21b is inserted into the through hole 10s of the connecting passage 10, that is, into the suction pipe 21a, with the through hole 10s of the connecting passage 10 and the through hole h of the partition plate 2a being combined, Airtightness can be increased.

(About exhalation suction part 5)
As described above, the exhalation suction part 5 does not need to be provided in particular. However, as shown in FIGS. 1 and 2, the flange part 5b is provided at the base end of the hollow tip part 5a formed in a cone shape. Fixing to the case 2 by the flange portion 5b is preferable because the connection passage 10 can be reliably fixed to the case 2.
In particular, if a sealing material is sandwiched between the front surface of the case 2 and the flange portion 5b, there is an advantage that the airtightness between the through hole a of the case 2 and the outer surface of the connection passage 10 can be increased. It is done.

(Replaceable trap 50)
Further, in FIG. 1, a configuration is provided in which a filter f that captures mist such as saliva contained in exhalation is provided at the tip of the exhalation suction unit 5 (or the tip of the connection passage 10 when the exhalation suction unit 5 is not provided). Is disclosed. In order to prevent the inhalation of the virus from the exhalation suction unit 5 while preventing saliva and the like from entering the connection passage 10, an exchangeable trap T that can be attached to and detached from the exhalation suction unit 5 is provided as follows. It is preferable to provide it.
For example, as shown in FIG. 5, a cylindrical member having a bottom (for example, a paper cup) having an opening at one end may be connected in a state where the openings are aligned to form an exchangeable trap T. . In this case, a through hole 51h is formed in the bottom of one member 51, and a through hole 52h is formed in the other member 52. And it is set as the structure which pinched | interposed the filter f which has air permeability between both members.
Then, if any of the members 51 and 52 in the replaceable trap 50 is attached to the hollow tip portion 5a of the exhalation suction portion 5, the air that has passed through the replaceable trap 50 can be caused to flow into the connection passage 10. . Therefore, it is possible to prevent saliva and the like from entering the connection passage 10 more effectively, and if the replaceable trap 50 is replaced whenever the subject changes, a virus or the like is infected from the exhalation suction unit 5 to the subject. The possibility can be reduced.

  As shown in FIGS. 5C and 5D, the exchangeable trap 50 has a difference in size between the through hole 51h and the through hole 52h so that the smaller hole diameter is located on the connection passage 10 side. Is preferably attached to the distal end portion 5 a of the exhalation suction portion 5. Then, it becomes easy to introduce the exhalation of the subject into the exchangeable trap 50, and the possibility that saliva or the like enters the connection passage 10 can be reduced.

  Further, the exchangeable trap 50 is not limited to the shape as described above, and can be attached to the hollow tip 5a of the exhalation suction part 5, and the exhaled air blown to one end is connected to the connection passage 10 via a filter or the like. Any structure having a path that can be supplied may be used.

  The breath test apparatus of the present invention is suitable for an apparatus for investigating infection with a pathogen in a place where many people pass, such as a port facility such as an airport or a station.
