[0028] <Explanation of virus collection device 1> 1, the virus collection device 1 is a device for collecting pathogenic microorganisms, and is a device capable of collecting pathogenic microorganisms that cause infectious diseases in living organisms such as bacteria and fungi by sucking them together with air. In this specification, "pathogenic microorganisms" includes various viruses.

[0029] The virus collection device 1 according to this embodiment includes a tubular section 10, a flange section 20 provided at one end of the tubular section 10, a first electrode 30 disposed inside the tubular section 10, and a virus collection section 40 disposed opposite the first electrode 30. Note that black circles in the drawings represent pathogenic microorganisms such as viruses.

[0030] The tubular part 10 is a cylindrical member that is open at both ends, and when the virus collection device 1 is placed at rest, the central axis is disposed in a direction parallel to the perpendicular direction to the ground surface.

[0031] The flange portion 20 is an annular portion provided at one end of the tubular portion 10, and is a member provided at the edge of an opening formed on one end side of the tubular portion 10 that faces the virus collection part 40 when the virus collection device 1 is placed at rest. The flange portion 20 is provided with a larger diameter in the direction perpendicular to the central axis of the tubular portion 10.

[0032] The first electrode 30 is an electrode disposed in the internal space of the tube section 10. A power source is connected to the first electrode 30, and a current is supplied from the power source. The first electrode 30 is an electrode having a needle-like, brush-like, or bristle-like longitudinal axis, and the longitudinal axis direction of the first electrode 30 is disposed in the same direction as the central axis of the tube section 10 (the longitudinal axis direction or parallel direction of the tube section 10). At this time, with the virus capture device 1 in a stationary state, a corona discharge is generated in the lower end and the tip direction of the lower end of the first electrode 30 to charge the pathogenic microorganisms. The corona discharge electrically decomposes the air present around the first electrode 30, generating ionic substances. When a pathogenic microorganism enters the area where the corona discharge is generated, positive ions are imparted to the particles of the pathogenic microorganism, and the pathogenic microorganism is positively charged. The tip of the protrusion of the first electrode 30 is disposed so as not to exceed the opposing surface of the flange section 20 disposed opposite the virus capture section 40. Moreover, the first electrode 30 is disposed so as to overlap the central axis of the tubular part 10 or in the vicinity of the central axis of the tubular part 10. In this specification, the brush-like first electrode 30 includes a bundle of about 6,000 carbon nanofibers with a diameter of about 6 μm.

[0033] Moreover, the first electrode 30 is attached to a locking member, so that it can be placed in the virus collection device 1. The locking member is a flat member with multiple holes formed therein, and has a locking point at the center where a part of the first electrode 30 can be locked.

[0034] The virus trapping section 40 is a container member that traps pathogenic microorganisms charged by the first electrode 30. The virus trapping section 40 contains a medium such as a plate, sheet, nonwoven fabric, or gel-like substance as a container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose, and the pathogenic microorganisms that are charged by the first electrode 30 and fall due to the action of Coulomb force are trapped, and the pathogenic microorganisms are prevented from diffusing to the surroundings. When the virus trapping device 1 is left stationary, an opening is formed in the opposing portion of the virus trapping section 40 that is disposed opposite the flange section 20. In addition, the medium contained in the virus trapping section 40 is contained in an amount that does not exceed the opening of the virus trapping section 40. In addition, the outer diameter of the flange section 20 is smaller than the outer diameter of the opening (opening) of the virus trapping section 40. Therefore, in the virus trapping device 1, a gap is formed between the flange section 20 and the virus trapping section 40.

[0035] When the virus trapping device 1 is in a stationary state, the distance from the lower end of the first electrode 30 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, or gel-like substance as the container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in the virus trapping unit 40 can be in the range of 5 mm to 50 mm in linear distance. If the distance from the lower end of the first electrode 30 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, or gel-like substance as the container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in the virus trapping unit 40 is less than 5 mm in linear distance, it becomes difficult to maintain the space between the liquid surface or solid surface and the first electrode 30, and there is a high possibility of inconvenience occurring in terms of handling and maintenance of the virus trapping device 1 due to shaking, etc. Furthermore, if the linear distance from the lower end of first electrode 30 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, or gel-like substance formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in virus capture unit 40 exceeds 50 mm, the voltage required to achieve a capture effect on pathogenic microorganisms will be too high. In this embodiment, a length of approximately 10 mm will be assumed as an example and will be described.

[0036] Here, the inner diameter (L1) of the tube section 10 can be 5 times or less the linear distance (L2) from the lower end of the first electrode 30 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, or gel-like substance formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in the virus capture section 40, and is preferably 3.5 times or less and 2.5 times or more, more preferably 3.5 times or less and 2.8 times or more, and even more preferably 3.2 times or less and 2.8 times or more. When L1>L2×5, the possibility that pathogenic microorganisms will pass through the discharge area of ​​the first electrode 30 decreases, and they can be transported by the air current without passing through the discharge area.

[0037] The virus trapping device 1 further includes a fan unit 50. The fan unit 50 is a blower that is connected to the other end of the tube unit 10 and blows air from the other end of the tube unit 10 into the inside of the tube unit 10. A power source for driving the fan unit 50 is connected to the fan unit 50, and the fan unit 50 blows air from the other end of the tube unit 10 into the inside of the tube unit 10 by power from the power source. The blowing function of the fan unit 50 allows air to be taken in from outside the virus trapping device 1 into the interior of the virus trapping device 1, and at the same time, pathogenic microorganisms contained in the air can also be taken into the interior of the device.

[0038] <Operational explanation of virus collection device 1> Next, the operation of the virus trapping device 1 will be described with reference to the drawings.

[0039] 3, when the virus trapping device 1 is driven, gas such as air is drawn into the virus trapping device 1 by the action of the fan section 50. At that time, pathogenic microorganisms in the air are also drawn into the virus trapping device 1.

[0040] Next, the pathogenic microorganisms taken into the inside of the virus collecting device 1 are carried by the air current and pass through the tubular part 10. The pathogenic microorganisms that have passed through the tubular part 10 are transported toward the area where the first electrode 30 is generating a corona discharge.

[0041] Pathogenic microorganisms that reach the area where corona discharge is occurring at the first electrode 30 are given an electric charge by the corona discharge and are thus charged. The charged pathogenic microorganisms are captured by the virus capture unit 40 due to Coulomb force. Then, due to the action of the fan unit 50, the air in which the pathogenic microorganisms have been captured moves on the air current beyond the area where corona discharge is occurring.

[0042] The air in which the pathogenic microorganisms have been captured is transported to the outside of the virus trapping device 1 through the gap formed between the flange portion 20 and the virus trapping portion 40.

[0043] Even after the air in which pathogenic microorganisms have been captured is transported outside the virus capture device 1, the desired amount of air is taken into the virus capture device 1, and the above process is repeated until the desired amount of pathogenic microorganisms is captured.

[0044] In this way, the pathogenic microorganisms captured by the virus capturing section 40 can be sent to various testing institutions, and can also be sent to research institutions as appropriate.

[0045] According to the virus collection device 1 of the present embodiment configured as described above, the virus collection device 1 includes a tube section 10, a flange section 20 provided at one end of the tube section 10, a first electrode 30 provided on the tube section 10 and discharged, and a virus collection section 40 arranged opposite the first electrode 30. In more detail, in the prior art, various devices for removing airborne viruses and aerosols are known, for example, a technology is known that includes a charged electrode having a structure in which a first plate electrode without thorns and a second plate electrode with thorns are stacked in the axial direction of a ground electrode via an insulating member. However, since the first plate electrode without thorns and the second plate electrode with thorns extend in the surface direction of the inner diameter of the ground electrode, such a structure in which the electrodes are stacked in the axial direction of the ground electrode can hinder the collection of viruses in the axial direction, making it difficult to efficiently collect viruses. In contrast, the virus collection device 1 of the present embodiment can collect pathogenic microorganisms such as viruses without having a stacking structure in the axial direction of the grounding electrode, thereby enabling efficient collection of pathogenic microorganisms such as viruses.

[0046] Furthermore, in the virus collection device 1 of this embodiment, as described above, the first electrode 30 may be needle-shaped or brush-shaped and disposed in parallel to the longitudinal axis of the tubular portion 10. In this case, discharge can be effectively performed at the first electrode 30.

[0047] Furthermore, in the virus collection device 1 of this embodiment, as described above, the first electrode 30 may be arranged so as to overlap with or be located near the central axis of the tubular section 10. In this case, by specifying the location of the first electrode 30 based on the central axis as the base point, pathogenic microorganisms can be efficiently collected.

[0048] Furthermore, as described above, virus collection device 1 of this embodiment may further include fan section 50 that is connected to the other end of tubular section 10 and sends air from the other end of tubular section 10 into the inside of tubular section 10. In this case, pathogenic microorganisms can be efficiently taken into the inside of virus collection device 1 from the other end of tubular section 10.

[0049] Furthermore, in virus capture device 1 of the present embodiment, as described above, the outer diameter of flange portion 20 may be smaller than the outer diameter of the opening of virus capture part 40. In this case, a gap is formed between flange portion 20 and virus capture part 40, and air after pathogenic microorganisms have been captured by virus capture device 1 can be exhausted through the gap.

[0050] Furthermore, in the virus trapping device 1 of the present embodiment, as described above, a corona discharge may be generated on the first electrode 30. In this case, pathogenic microorganisms can be efficiently trapped.

[0051] Furthermore, in virus trapping device 1 of the present embodiment, as described above, virus trapping section 40 may contain a plate, sheet, nonwoven fabric, or gel-like substance as a container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose. In this case, pathogenic microorganisms charged by first electrode 30 can be continuously trapped in virus trapping section 40.

[0052] The virus trapping device 1 according to this embodiment is not limited to the above-mentioned embodiment.

[0053] The virus collection device 1 according to this embodiment may further include a second electrode 60 arranged on the flange portion 20, as shown in FIG. 4. The second electrode 60 is a non-dischargeable annular, plate-shaped electrode, and has the same or approximately the same size as one surface of the flange portion 20. A power source is connected to the second electrode 60, and a current is supplied from the power source. The second electrode 60 has the same or approximately the same shape as one surface of the flange portion 20. The second electrode 60 is provided on one surface of the flange portion 20, on one surface (opposing surface) of the flange portion 20 arranged opposite the virus collection portion 40.

[0054] At this time, the distance from the lower surface of the second electrode 60 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, gel-like substance as the container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in the virus capture unit 40 can be in the range of 3 mm to 20 mm in linear distance. If the distance from the lower surface of the second electrode 60 to the liquid surface or solid surface of the plate, sheet, nonwoven fabric, gel-like substance as the container formed of at least one of water, colloid, water-soluble gelatin, polyvinyl alcohol, polyacrylamide, and carboxymethyl cellulose contained in the virus capture unit 40 is less than 3 mm in linear distance, it becomes difficult to suppress manufacturing tolerance. In addition, if this distance exceeds 20 mm, the pathogenic microorganism capture performance of the virus capture device 1 will decrease. In this embodiment, from the viewpoint of both suppressing manufacturing tolerance and capturing performance of pathogenic microorganisms, a length of about 10 mm is assumed and described as an example.

[0055] A positive voltage is applied to the second electrode 60, and an electrostatic field is formed by not discharging. Then, with the electrostatic field formed, pathogenic microorganisms positively charged by the first electrode 30 are captured in the virus capture section 40 by the action of Coulomb force. In this way, the first electrode 30 and the second electrode 60 are not electrically connected to each other.

[0056] In addition, in the virus trapping device 1 according to the present embodiment, the first electrode 30 is disposed in the internal space of the tube section 10, but the present invention is not limited thereto. As shown in FIG. 5, for example, the virus trapping device 1 may include a tube section 10, a flange section 20 provided at one end of the tube section 10, a second electrode 60 provided at the flange section 20, and a virus trapping section 40 disposed opposite the second electrode 60, and the first electrode 30 may be disposed along the inner peripheral edge of the flange section 20. In this case, the first electrodes 30 are arranged adjacent to each other along the inner peripheral edge of the flange section 20. Alternatively, the first electrodes 30 may be arranged at a predetermined interval as long as the effect of the virus trapping device 1 is achieved. In addition, the first electrode 30 and the second electrode 60 are not connected to each other and are not electrically connected to each other. In the virus collection device 1 of this type, pathogenic microorganisms can be charged in the area where corona discharge is generated, which is formed along the inner periphery of the flange portion 20, so that the pathogenic microorganisms can be collected more reliably. The first electrode 30 may be disposed along the outer periphery of the flange portion 20.

[0057] In addition, in the virus trapping device 1 according to the present embodiment, the fan section 50 is connected to the other end of the tube section 10, and the fan section 50 blows air from the other end of the tube section 10 into the inside of the tube section 10, but the present invention is not limited to this. As shown in FIG. 6, for example, the virus trapping device 1 may include the tube section 10, the flange section 20 provided at one end of the tube section 10, the second electrode 60 provided at the flange section 20, and the virus trapping section 40 arranged opposite the second electrode 60, and the first electrode 30 may be arranged along the outer periphery of the flange section 20. In this case, the first electrodes 30 are arranged adjacent to each other along the outer periphery of the flange section 20. Alternatively, the first electrodes 30 may be arranged at a predetermined interval as long as the effect of the virus trapping device 1 is achieved. In addition, the first electrode 30 and the second electrode 60 are not connected to each other and are not electrically connected to each other. At this time, the fan unit 50 is connected to the other end of the tube unit 10 and blows air from the other end of the tube unit 10 to the outside of the tube unit 10. In the virus trapping device 1 of this type, pathogenic microorganisms are sucked into the inside of the virus trapping device 1 through the gap formed between the flange unit 20 and the virus trapping unit 40, and the pathogenic microorganisms can be charged in an area where corona discharge is generated and formed along the outer peripheral edge of the flange unit 20. Since the outer peripheral edge of the flange unit 20 is longer than the inner peripheral edge, it is easier to reduce the flow speed of the fluid near the outer peripheral edge than the inner peripheral edge, and the residence time of the fluid in the area where corona discharge is generated can be extended. In this way, it is possible to more efficiently trap pathogenic microorganisms. In addition, the air in which the pathogenic microorganisms have been captured is transported from the tube unit 10 to the outside of the virus trapping device 1 via the fan unit 50.

[0058] In this case, the first electrode 30 is preferably brush-shaped, which allows corona discharge to be generated more efficiently.

[0059] In addition, in the virus trapping device 1 according to the present embodiment, the first electrode 30 and the second electrode 60 are not connected and are not electrically connected to each other, but the present embodiment is not limited to this as long as the virus trapping device 1 according to the present embodiment can trap pathogenic microorganisms. For example, the first electrode 30 and the second electrode 60 may be electrically connected. The first electrode 30 and the second electrode 60 are supplied with power from the same power source, and the same voltage is applied to the first electrode 30 and the second electrode 60. This can reduce labor.

[0060] In the present embodiment, an example has been described in which the tip of the projection of first electrode 30 does not extend beyond the opposing surface of flange portion 20 arranged opposite virus capture unit 40 when virus capture device 1 is placed at rest, but the present invention is not limited to this. For example, the tip of the projection of first electrode 30 may extend beyond the opposing surface of flange portion 20 arranged opposite virus capture unit 40 as long as the effect of the present embodiment is achieved.

[0061] Furthermore, in the present embodiment, an embodiment has been described in which the outer diameter of flange portion 20 is smaller than the outer diameter of the opening (opening) of virus collection portion 40, and a gap is formed between flange portion 20 and virus collection portion 40 in virus collection device 1, but this is not limiting. For example, so long as the effect of the present embodiment is achieved, in the case where the outer diameter of flange portion 20 and the outer diameter of the opening of virus collection portion 40 are the same or approximately the same, and therefore no gap is formed between flange portion 20 and virus collection portion 40, a hole may be formed in flange portion 20 to provide a function similar to that of a gap.

[0062] In the present embodiment, the first electrode 30 is a needle-like, brush-like, or bristle-like electrode, and the second electrode 60 is an annular, plate-like electrode, but the present invention is not limited to this. For example, as shown in FIG. 7, the first electrode 30 and the second electrode 60 may be brush-like electrodes. [Explanation of symbols]
