Description

  The present invention relates to a technique for recovering a powdery substance containing an environmental allergen on the surface of an inspection object.

  Conventionally, a method for collecting house dust sucked by a vacuum cleaner using a dust bag that can be attached to a vacuum cleaner is known as a sampling means for collecting a powdery substance containing this type of environmental allergen. (For example, refer to Patent Document 1).

  The sampling means will be described below with reference to FIG.

  As shown in the figure, the allergen collection unit 101, the allergen detection unit 102, and the antigen solution supply unit 103 are integrated on the mount 105, and the cleaner hose is attached to the cleaner hose insertion portion 106 on the mount 105. After that, house dust is collected in the vacuum cleaner dust collection bag 104 by collecting the dust with a vacuum cleaner, and the allergen is captured by the allergen collecting unit 101. The allergen captured by the allergen collecting unit 101 is dissolved in the antigen solution infiltrated from the antigen solution supply unit 103, and the allergen is detected by feeding the antigen solution into the allergen detection unit 102. In this way, sampling is performed by attaching the apparatus to the vacuum cleaner hose and collecting dust from the surface of the inspection object using the vacuum cleaner.

  Further, a wiping-type sample collection method is used for this type of sampling means (see, for example, Patent Document 2).

  Hereinafter, the sampling means will be described with reference to FIG.

As shown in the figure, the allergen detection unit 102 and the porous wiping pin 108 are integrated with the casing 107, and the allergen is collected by wiping the surface on which the allergen is falling using the wiping pin 108. Then, the allergen is dissolved in the antigen solution by dropping the antigen solution from the antigen solution supply unit 103 onto the wipe pin 108. The dissolved solution passes through the transport zone 110 and reaches the allergen detection unit 102 to detect the allergen. In this way, sampling is performed by rubbing the surface of the object to be inspected with a wiping pin.

(Embodiment 1)
As shown in FIG. 1, the sampling apparatus 1 includes a collecting unit 2, a sorting unit 3, and a collecting unit 4, and a moving unit 6 that moves the powdery substance 5 collected by the collecting unit 2 to the sorting unit 3. And a second moving means 7 for moving the powdery substance 5 selected by the selecting means 3 to the collecting means 4. The collecting means 2 forms the opening 8 for taking the powdery substance 5 into the collecting means 2 and the opening 8 to define the collection area 10 on the surface 9 to be inspected, and the powdery form. A capturing unit 12 that captures the substance 5, a sampling medium 13 that moves the powdery substance 5 from the collection region 10 to the capturing unit 12, a sampling medium supply unit 14 that contains the sampling medium 13, and the sampling medium 13 are captured. A sampling medium introducing means 15 to be introduced into the collecting area 10 and a second sampling medium introducing means 16 to introduce the sampling medium 13 introduced into the opening 8 from the collecting area 10 into the capturing section 12 are provided.

  Here, limiting the collection area 10 on the inspection object surface 9 means that the collection area 10 on the inspection object surface 9 is separated from the non-collection area, and is collected by the opening frame 11. By limiting the area 10, sampling can always be performed from the collection area 10 having the same area.

  In the above configuration, the opening frame 11 is brought into contact with the surface 9 to be inspected, the surface 9 to be inspected exposed to the opening 8 is used as the collection region 10, and the sampling medium 13 is moved by the sampling medium introducing means 15. By introducing into the collection area 10 from the supply unit 14 and filling the collection area 10, the powdery substance 5 on the collection area 10 is contained in the sampling medium 13. Next, the sampling medium 13 filled with the opening 8 and containing the powdery substance 5 is introduced into the capturing part 12 using the second sampling medium introducing means 16, so that the powdery substance 5 is introduced into the capturing part 12. To capture.

  Here, the contact between the opening frame 11 and the surface 9 to be inspected is in close contact so that the sampling medium 13 introduced onto the collection region 10 does not leak into the non-collection region. As shown, if the condition that the sampling medium 13 filled in the collection region 10 does not leak into the non-collection region can be satisfied, the contact between the opening frame 11 and the surface 9 to be inspected is not necessarily complete and there is a gap. Even if it is open, only the powdery substance 5 in the collection region 10 can be captured.

  The opening frame body 11 shown here is, for example, a ring-shaped metal or wooden box frame, and can perform a desired sampling as long as it can constitute a partitioned surface. In addition, the opening 8 shown here is a hole that is open on the inside of the ring-shaped metal ring or on the wooden box frame and is divided by the open frame body 11. The sampling medium 13 shown here is, for example, a liquid such as water or air, or a fluid such as gas. In this case, house dust or the like that is a powdery substance 5 is suspended from the surface 9 to be inspected. The powdery substance 5 is supplemented to the capturing unit 12 by moving the sampling medium 13 to the capturing unit 12. In addition, the liquid and gas which are the sampling media 13 are fluids, and if the thing which moves the powdery substance 5 to the capture | acquisition part 12 by the flow by a fluid is used, sampling other than water and air can also perform the same purpose sampling. . Further, when the sampling medium 13 is a fluid such as water or gas, it is necessary to make contact with the opening frame 11 and the surface 9 to be inspected without a gap so that the sampling medium 13 does not leak into the non-collecting region. Therefore, the opening frame 11 needs to be strongly pressed, for example, manually on the surface 9 to be inspected. The sampling medium 13 is a carrier such as an adhesive tape that adsorbs the collected powdery substance 5 or an adhesive gel. In this case, house dust or the like that is the powdery substance 5 adheres to the carrier. Then, the carrier 5 is captured by the capturing unit 12, whereby the powdery substance 5 is captured by the capturing unit 12. Even if the carrier that is the sampling medium 13 is not sticky, it can be separated from the surface 9 to be inspected by attaching or attracting the powdery substance 5. Target sampling is possible. Moreover, filling the sampling medium 13 shown here with the collection area | region 10 means that the sampling medium 13 contacts and covers all the to-be-inspected substance surfaces 9 on the collection area | region 10, If the entire surface can be contacted and covered, the surface of the object to be inspected on the collection region 10 may be the amount of the sampling medium 13 introduced into the collection region 10 is smaller or larger than the volume occupied by the opening 8. The powdery substance 5 can be collected from 9. The sampling medium supply unit 14 shown here can include, for example, a container or a bag-like fluid, or can hold a carrier, and can hold the sampling medium 13 separately from the opening 8. If so, sampling for the same purpose becomes possible. The sampling medium introduction means 15 shown here is, for example, a dropper or a pump that ejects a fluid that is the sampling medium 13, and is tweezers that drops the carrier that is the sampling medium 13 into the opening 8. The sampling for the same purpose can be performed as long as the sampling medium 13 that has been held can be separated from the sampling medium supply unit 14 and moved to the opening 8. Further, the second sampling medium introducing means 16 shown here is a means capable of separating the sampling medium 13 from the surface 9 to be inspected of the opening 8 and sucks the sampling medium 13 which is a fluid, for example. For example, a tweezer or a blower that picks up a carrier that is a sampling medium 13 that has fallen into the collection region 10. Further, the capturing unit 12 shown here can hold the sampling medium 13 separated from the surface 9 to be inspected by the second sampling medium introducing means 16, and is, for example, the sampling medium 13. It is a tweezers or a blower that can pick up a carrier that is a sampling medium 13 or a container or bag that can supplement a fluid. In addition, if the sampling medium 13 can be separated from the collection region 10 and can be held firmly, sampling for the same purpose can be performed even if it is other than the above. The moving means 6 shown here is, for example, a pump or a dropper for moving the sampling medium 13 that is a fluid, and is a tweezer or a blower that moves the carrier that is the sampling medium 13. For example, when the sampling medium 13 is water, the water containing the powdery substance 5 is moved to the sorting means 3 by the moving means 6 that is a pump, for example, from the capturing unit 12 configured by a container, for example. Moved to sorting means 3. The sorting means 3 shown here will be described in detail in the twelfth embodiment. For example, the sorting means 3 is composed of a net woven from metal or wood as the sieving means 23, and is composed of, for example, a pump. The collecting means 2 is arranged by a moving means 6 arranged so that one end of the pump is in contact with the surface 9 to be inspected in the collecting area 10 and the other end is arranged above the sieving means 23 of the sorting means 3. The powdery substance 5 is moved to the sorting means 3, and the moved powdery substance 5 is sorted according to the size of the mesh that constitutes the sieve, and the powdery substance 5 that cannot pass through the mesh is placed on the sieve. Only the powdery substance 5 that has passed through the sieve can be sampled. The second moving means 7 is, for example, a pump or a dropper for moving the sampling medium 13 that is a fluid. For example, the powdery substance that is selected by the selecting means 3 that is the sieving means 23 and falls under the sieve. By sucking 5 with a pump or the like and moving it to the recovery means 4, the powdered material 5 that has been separated is recovered by the recovery means 4. The collection means 4 shown here will be described in detail in the sixteenth embodiment. For example, a container formed of glass or plastic and removable from the collection means 4 is installed inside the collection means 4. For example, the powdery substance 5 moved from the sorting means 3 by the second moving means 7 constituted by a pump is collected in a container such as glass or plastic.

  This sampling apparatus 1 is a specific example that can exist in the powdery substance 5 on the surface 9 to be inspected, with a flat area such as a room floor surface, wall surface, or ceiling surface in the living environment as the object to be inspected. Used for sampling purposes to measure or detect the abundance of a substance. Here, the object to be inspected does not necessarily have to be a flat area inside the floor, wall surface, ceiling surface or the like, but may be an outdoor area such as a rooftop or a garden where the subject can move with the sampling device 1. Any of these can be sampled for the same purpose. In addition, even if the object to be inspected is an object installed in the environment such as a television, table, chair, or car, or clothes or ornaments worn by the subject, it has a surface or surface to be inspected. Any one that can form the signal can be sampled for the same purpose. In addition, the powdery substance 5 on the surface 9 to be inspected is, for example, animal and plant bodies such as house dust falling on the floor surface, mites and pollen contained in the hair of the carpet, and on the table surface. If there is something other than the object to be inspected that exists on the object to be inspected and can be powdered, it adheres to the surface 9 of the object to be inspected. Can be sampled for the same purpose. The specific substances sampled and measured or detected by the sampling device 1 include animals and plants such as mite allergens, pollen and pods, and molecules produced by animals and plants such as estradiol and plant alkanoids, and these molecules. It is a substance that can contain, or compounds such as dioxins, PCBs, flame retardant bromine-based compounds such as environmental hormones and residual organic compounds, and those compounds that can contain these compounds. In addition, what can contain a specific substance to be measured or detected is that a specific substance is attached to something other than the specific substance by an intermolecular interaction, It does not matter even if it is tightly coupled.

  In the above configuration, sampling can always be performed from the collection area 10 having the same area, and the powdery substance 5 can be obtained easily and with good reproducibility.

(Embodiment 2)
FIG. 2 shows a method of collecting the powdered substance 5 by the collecting means 2 of the sampling device 1 shown in the first embodiment. The same parts as those in the first embodiment are given the same numbers and are described in detail. Description is omitted. In FIG. 2, the opening frame 11 is brought into contact with the surface 9 to be inspected as shown in FIG. 2 a), and the surface 9 to be inspected exposed to the opening 8 is used as the collection region 10, as shown in FIG. The sampling medium 13 is introduced into the collection area 10 from the sampling medium supply unit 14 by the sampling medium introduction means 15 to fill the collection area 10, so that the powdery substance 5 on the collection area 10 is contained in the sampling medium 13. Next, as shown in FIG. 2c), the sampling medium 13 filled in the opening 8 and containing the powdery substance 5 is introduced into the capturing part 12 by using the second sampling medium introducing means 16, whereby the powdery substance 5 Is captured in the capturing unit 12.

  Here, the contact between the opening frame 11 and the surface 9 to be inspected is in close contact so that the sampling medium 13 introduced onto the collection region 10 does not leak into the non-collection region. As shown, if the condition that the sampling medium 13 filled in the collection region 10 does not leak into the non-collection region can be satisfied, the contact between the opening frame 11 and the surface 9 to be inspected is not necessarily complete and there is a gap. Even if it is open, only the powdery substance 5 in the collection region 10 can be captured.

  The opening frame body 11 shown here is, for example, a ring-shaped metal or wooden box frame, and can perform a desired sampling as long as it can constitute a partitioned surface. Moreover, the opening part 8 shown here is a place where the inside of the ring-shaped metal ring or the wooden box frame is open, and is a hole partitioned by the open frame body. The sampling medium 13 shown here is, for example, a liquid such as water or air or a fluid such as gas. In this case, the sampling medium 13 is filled in the collection region 10 and is the powdery substance 5. House dust or the like is suspended from the surface 9 to be inspected, and the house dust is taken into water. The powdery substance 5 is captured by moving the water containing the house dust to the capturing unit 12 by the sampling medium introducing unit 15 that is, for example, a pump disposed at the lower end of the collecting unit 2 so as to contact the collecting region 10, for example. Part 12 is supplemented. In addition, the liquid and gas which are the sampling media 13 are fluids, and if the thing which moves the powdery substance 5 to the capture | acquisition part 12 by the flow by a fluid is used, sampling other than water and air can also perform the same purpose sampling. . The sampling medium 13 is a carrier such as an adhesive tape that adsorbs the collected powdery substance 5 or an adhesive gel. In this case, house dust or the like that is the powdery substance 5 adheres to the carrier. Then, the carrier 5 is captured by the capturing unit 12, whereby the powdery substance 5 is captured by the capturing unit 12. Even if the carrier that is the sampling medium 13 is not sticky, it can be separated from the surface 9 to be inspected by attaching or attracting the powdery substance 5. Target sampling is possible. Moreover, filling the sampling medium 13 shown here with the collection area | region 10 means that the sampling medium 13 contacts and covers all the to-be-inspected substance surfaces on the collection area | region 10, and the surface of the collection area | region 10 is shown. If the entire surface can be touched and covered, the amount of the sampling medium 13 introduced into the collection region 10 may be less than or greater than the volume occupied by the opening 8 and the surface 9 to be inspected on the collection region 10. From this, the powdery substance 5 can be collected. The sampling medium supply unit 14 shown here can include, for example, a container or a bag-like fluid, or can hold a carrier, and can hold the sampling medium 13 separately from the opening 8. If so, sampling for the same purpose becomes possible. The sampling medium introduction means 15 shown here is, for example, a dropper that ejects a fluid that is the sampling medium 13 or tweezers that drops the carrier that is the sampling medium 13 into the opening 8. If the sampling medium 13 can be separated from the sampling medium supply unit 14 and moved to the opening 8, sampling for the same purpose can be performed. Further, the second sampling medium introducing means 16 shown here is a means capable of separating the sampling medium 13 from the surface 9 to be inspected of the opening 8 and sucks the sampling medium 13 which is a fluid, for example. It is a forceps that picks up a carrier that is a sampling medium 13 that has fallen into the collection area 10 and a dropper that can be used. Further, the capturing unit 12 shown here can hold the sampling medium 13 separated from the surface 9 to be inspected by the second sampling medium introducing means 16, and is, for example, the sampling medium 13. It is a tweezers that pinches a container or a bag-like one that can supplement a fluid, or a carrier that is a sampling medium 13. As long as the sampling medium 13 can be separated from the collection region 10 and can be held firmly, the sampling for the same purpose can be performed.

  In the above configuration, the powdery substance 5 on the surface 9 to be inspected always having the same area can be sampled easily and with good reproducibility.

(Embodiment 3)
FIG. 3 shows the collecting means 2 in which the opening frame 11 shown in the second embodiment is made of a material having elasticity or plasticity. The same parts as those in the second embodiment are denoted by the same reference numerals. Detailed description is omitted.

This prevents the sampling medium 13 from leaking into the non-collection area when the sampling medium 13 shown in the second embodiment is filled in the collection area 10.

  In the above configuration, the material having elasticity or plasticity is a material that can be easily deformed, such as rubber or sponge, but the deformation of the opening frame 11 occurs in a direction perpendicular to the surface 9 of the object to be inspected. If so, the shape and area of the opening 8 can be kept constant, and the sampling medium 13 leaks into the non-collection area in accordance with the shape of the surface 9 to be inspected while keeping the collection area 10 constant. Sampling for the same purpose can be performed without any problem. Here, the sampling area 13 is separated from the collection area 10 and the non-collection area of the surface 9 to be inspected, for example, a plate having a protrusion and depression by the deformable opening frame 11, and the sampling medium 13, for example, water is collected. The collection means 2 is manually pressed onto the surface 9 to be inspected, for example, so that it does not leak into the non-collection area even if it is introduced into the collection area 10. Even if the sampling medium 13 filled on the collection region 10 is water even if the surface of the non-inspection object is uneven due to the deformation of the opening frame 11 on the surface of the non-inspection object, the non-collection Without leaking into the area, only the powdery substance 5 that is, for example, house dust on the collection area 10 is taken into the water, and the water is moved to the capturing unit 12 by the second sampling medium introduction means 16 that is, for example, a pump. Thus, the powdery substance 5 is captured by the capturing unit 12.

  In the above configuration, sampling can be performed with good reproducibility from the powdery substance 5 on the surface 9 to be inspected having unevenness.

Here, the powdery substance 5 is, for example, house dust, and the sampling medium 13 is, for example, water, and is disposed at the lower end of the collecting means 2 so as to contact the water containing the house dust with the collecting region 10, for example. By moving the sampling medium introduction means 15 which is a pump to the capture unit 12, house dust is supplemented to the capture unit 12.

  Even if the sampling medium introduction means 15 is other than a pump, if the sampling medium 13 can be made to flow automatically like a pump, the sampling medium 13 that is, for example, water can be collected more easily. Region 10 can be filled. Further, even if the sampling medium supply unit 14 and the capturing unit 12 are made the same and the sampling medium introduction unit 15 and the second sampling medium introduction unit 16 are made the same sampling, the same purpose sampling is possible. Simplification and miniaturization are possible.
