Japanese Unexamined Patent Publication No. 2001-321364 Japanese Patent Publication No. 2011-515171 Japanese Patent No. 2805463

However, in the self-collection kits described in Patent Documents 1 and 2, when the fluid to be inspected such as blood once collected is transferred from the collection member to the storage container, the work of turning over the collection member after attaching the collection member to the storage container is performed. It was necessary to do the work, or to place the mouth of the storage container on the tip side of the sampling member and transfer it while taking care not to spill the fluid to be inspected. Further, in the self-collecting kit described in Patent Document 1, there is a possibility that blood may be scattered at the time of blood collection and stain may be generated at the time of use.

Therefore, an object of the present invention is to provide an inspection unit capable of easily transferring the inspection target fluid from the collection member to the storage container after collecting the inspection target fluid such as blood.

The present invention relates to an inspection unit as one aspect thereof. This inspection unit includes a sampling member for collecting the fluid to be inspected and a storage container for accommodating the fluid to be inspected collected by the sampling member, and the sampling member is a hollow thin tube extending from the tip to the base end. It has a portion and a hollow fitting portion provided on the base end side of the thin tube portion, and the storage container has a bottomed tubular container body having an opening at one end and a lid that can open and close the opening of the container body. It has a body, and the fitting portion of the collection member is configured so that it can be fitted to one end of the storage container, and a gap for letting air in the storage container escape to the outside is fitted between the collection member and the storage container. It is provided in the joint area.

In this inspection unit, the fitting portion of the sampling member is configured so that it can be fitted to one end of the storage container, and moreover, a gap for letting air in the storage container escape to the outside is formed between the sampling member and the storage container. It is provided in the fitting area of. In this case, after the liquid to be inspected such as blood is collected by the capillary part of the collecting member by using the capillary phenomenon or the like, a predetermined force is applied to the thin tube part or the fluid to be inspected to store the fluid to be inspected in the capillary part. The air in the containment vessel can smoothly escape outward from the gap in the fitting region in the middle as the fluid to be inspected moves when it is attempted to move downward. Therefore, according to this inspection unit, the fluid to be inspected collected in the thin tube portion can be easily moved into the storage container. As a result, according to this inspection unit, it is possible to easily transfer the inspection target fluid from the collection member to the storage container after collecting the inspection target fluid such as blood. It should be noted that this gap is intended to allow a part of the air in the storage container to escape to the outside, and therefore does not need to be an excessive gap. Therefore, even if such a gap is provided, it is subject to inspection. The effect on the fluid can be minor.

In the above inspection unit, the sampling member may be attached to the storage container so that the fitting portion is joined to the inner peripheral portion of the opening of the storage container. In this case, it becomes easy to provide a gap located in the fitting region between the collecting member and the storage container, and since the fitting portion is not arranged on the outer peripheral side of the storage container, a connecting member that connects the lid to the container body. Can be easily provided on the outer circumference of the container body.

In the above inspection unit, the sampling member further has a flange portion between the thin tube portion and the fitting portion, a protrusion is provided on the surface of the flange portion on the fitting portion side, and the gap is defined by the protrusion. You may. Further, a groove extending in a direction intersecting the circumferential direction may be formed on the outer periphery of the fitting portion, and the groove may form at least a part of the gap. By providing the gap or the member defining the gap on the sampling member (fitting portion) side in this way, the shape of the storage container side, particularly the portion to be fitted with the fitting portion, is made simple or flat. be able to. For this reason, for example, when performing a test such as self-collection of blood, it is necessary to fit the lid into the opening of the container after storing the test solution and tightly seal it before sending it to the testing institution. Since the opening side of the storage container can be formed into a smooth (flat surface) shape, the sealing property of the storage container by the lid can be easily improved.

In the above inspection unit, the inner hole of the thin tube portion may be tapered from the tip end to the base end of the sampling member. The sampling member of the inspection unit described above can be designed on the assumption that the fluid to be inspected enters the inner hole of the capillary portion by utilizing the so-called capillary phenomenon, but the inner diameter on the base end (containment container) side is from the tip side. By forming the fluid so as to spread, when a predetermined force is applied to the capillary portion or the fluid to be inspected, the fluid to be inspected in the capillary portion can easily move to the lower storage container due to gravity or the like. More specifically, by increasing the inner diameter of the inner hole on the proximal end side of the capillary portion, the capillary phenomenon in that region is weakened, and the fluid to be inspected once collected can be easily moved to the storage container side. It will be possible to keep it. As described above, according to the above configuration, it is possible to more easily transfer the test target fluid from the collection member to the storage container after collecting the test target fluid such as blood. In this case, it is preferable that the minimum inner diameter of the inner hole of the thin tube portion is twice or more the minimum inner diameter of the tip end side thereof from the viewpoint of ease of transfer.

In the above inspection unit, at least one first guide rib extending in the longitudinal direction intersecting the circumferential direction is provided on the inner peripheral surface of the container body of the container, and the first guide rib extends to the front of the opening. You may. In this case, when a part of the fluid to be inspected collected and held by the sampling member, for example, the lower end thereof touches the first guide rib in the container, it is stored along the first guide rib by suction of surface tension or the like. It becomes easy to be guided into the container. Therefore, by providing such an induction rib, it becomes possible to more easily transfer the test target fluid from the collection member to the storage container after collecting the test target fluid such as blood. In this case, at least one second guide rib extending in the longitudinal direction intersecting the circumferential direction is provided on the inner peripheral surface of the fitting portion located on the storage container side, and the second guide rib is the collecting member and the storage container. It is preferable that the first guide rib can be contacted when the and is fitted. In this case, the fluid to be inspected in the sampling member is first guided to the storage container side by the first guide rib, and then guided into the storage container by the second guide rib, so that the sampling member is guided to the storage container. Even more easily, it can be transferred. In this case, it is preferable that the first lead rib and the second lead rib are provided with different numbers. With such a configuration, it is possible to easily switch between the case where the first guide rib and the second guide rib are in contact with or close to each other and the case where the first guide rib and the second guide rib are not in contact with each other. It can be adjusted by aligning the ribs.

The above test unit is not limited to blood tests, and can be used for urine and other fluids to be tested. However, when used for blood tests, the storage container is used for blood tests. It is preferable that the plasma separating agent of the above is contained. In this case, the speed and accuracy of the test can be improved by separating only plasma from the blood in advance before the test.

According to the present invention, it is possible to provide an inspection unit capable of easily transferring the inspection target fluid from the collection member to the storage container after collecting the inspection target fluid such as blood.

FIG. 3 is a perspective view showing a sampling member constituting the inspection unit shown in FIG. 1 from below. As shown in FIGS. 1 to 3, the collecting member 20 has a nozzle shape as a whole, and mainly includes a thin tube portion 21, a fitting portion 22, and a flange portion 23. Such a sampling member 20 can be integrally formed by injection molding a transparent resin such as polypropylene (PP), polystyrene (PS), acrylonitrile styrene (AS), or polyethylene (PE).

The thin tube portion 21 has a hollow substantially conical tubular shape having an inner hole 21a, and is a thin tube formed so as to extend from the tip end 21b toward the base end 21c. The thin tube portion 21 has a tapered outer shape, but may have a straight shape. The inner diameter of the inner hole 21a of the thin tube portion 21 is, for example, 0.5 mm to 5 mm so that the fluid to be inspected can be collected by the capillary phenomenon, and the inner diameter of the tip 21b is, for example, in the range of 0.5 mm to 2 mm. ing. Further, the inner hole 21a of the thin tube portion 21 is formed so as to taper from the tip 21b toward the base end 21c, and the inner diameter of the inner hole 21a on the base end 21c side is larger than the inner diameter of the tip 21b side. It has become. More preferably, when the inner diameter of the inner hole 21a on the base end 21c side is twice or more the inner diameter of the tip 21b side, for example, when the inner diameter of the inner hole 21a on the tip 21b side is 1 mm, the base end of the inner hole 21a The inner diameter on the 21c side is 2 mm or 3 mm or more. The amount of blood or the like collected at one time by the capillary portion 21 is, for example, about 100 μL to 150 μL.

The fitting portion 22 is a hollow substantially cylindrical member provided on the base end 21c side of the thin tube portion 21 and is fitted into the opening 33 of the storage container 30 to attach the sampling member 20 to the storage container 30. Is the part of. The fitting portion 22 has an inner hole 22a having a diameter larger than that of the inner hole 21a of the thin tube portion 21. The inner hole 22a is continuously configured so as to be fluidly communicated with the inner hole 21a of the thin tube portion 21. That is, the fluid to be inspected collected in the inner hole 21a of the thin tube portion 21 can move to the storage container 30 through the inner hole 22a. A plurality of ribs 25 (three ribs in this embodiment, see FIG. 3) are provided at equal intervals (equal angles) on the outer peripheral surface of the fitting portion 22, and the tops of these ribs 25 are storage containers. By joining to the inner circumference of the opening 33 of 30, the fitting portion 22 is fitted into the storage container 30. Since such ribs are provided in the circumferential direction, a gap 26 is defined between the outer peripheral surface of the fitting portion 22 (excluding the rib 25 forming region) and the inner peripheral surface of the storage container 30. The air in the storage container 30 can escape to the outside through the gap 26.

The flange portion 23 is a member on a disk provided between the thin tube portion 21 and the fitting portion 22, and has an outer circumference having a diameter larger than the outer circumference of the thin tube portion 21 and the fitting portion 22. The outer circumference of the flange portion 23 is, for example, substantially the same as the outer circumference of the storage container 30, and when the fitting portion 22 is fitted into the opening 33 of the storage container 30, the outer peripheral portion thereof is on the upper end of the drawing of the storage container 30. Is arranged so that it is caught. A plurality of protrusions 24 (three protrusions in the present embodiment) are provided on the lower surface 23a of the flange portion 23 at equal intervals in the circumferential direction, and the flange portion 23 is provided with the accommodation container 30 via these protrusions 24. It is placed at the top of. Since such a protrusion 24 is provided on the lower surface 23a of the flange portion 23, a gap 26 is defined between the lower surface 23a of the flange portion 23 (excluding the region where the protrusion 24 is formed) and the upper end of the storage container 30. Then, the air in the storage container 30 can escape to the outside through the gap 26.

4A and 4B are perspective views showing a storage container constituting the inspection unit shown in FIG. 1, where FIG. 4A shows a state when the lid is opened, and FIG. 4B shows a state when the lid is closed. Shown. As shown in FIGS. 1, 2 and 4, the storage container 30 includes a container body 31 and a lid 32. The container body 31 and the lid 32 of the storage container 30 are each formed by injection molding a resin such as transparent polypropylene (PP), polystyrene (PS), acrylonitrile styrene (AS), or polyethylene (PE). Can be done. In the storage container 30, in order to prevent the lid 32 from being lost, the container body 31 and the lid 32 may be connected to each other by a connecting member 34, and the connecting member 34 is integrally molded with the lid 32. You may.

The container body 31 is a bottomed cylindrical container having one end open, and is composed of, for example, a cylindrical container. The inner peripheral surface of the opening 33 of the container body 31 is flat so that when the lid 32 is closed, the opening 33 can be easily sealed by the lid 32. That is, the lid 32 is configured so that the opening 33 can be opened and closed. The size of the container body 31 is not particularly limited as long as it can accommodate the liquid to be inspected (for example, blood).

Subsequently, the blood collection operation by the inspection unit composed of the collection member 20 having such a configuration and the storage container 30 will be described with reference to FIG. 5A and 5B are views showing an example of use of the test unit shown in FIG. 1, FIG. 5A shows a method for collecting blood, and FIG. 5B shows a method for transferring the collected blood to a storage container. Shown.

As shown in FIG. 5A, in order to collect blood to be tested, first, a blood sampling needle (not shown) is pointed at the finger or the like of the test subject to make blood flow, and then the test unit 10 is used. The test unit 10 is arranged so that the tip of the collection member 20 is in contact with the blood B. With such an arrangement, blood B is collected so as to advance in the inner hole 21a of the capillary portion 21 of the collection member 20 toward the proximal end 21c due to the capillary phenomenon. Since the test unit 10 collects blood B by utilizing the capillary phenomenon, it is not necessary to use a bag provided at one end of the blood B like a dropper to create a negative pressure inside.

Subsequently, when blood B to be inspected is collected in the thin tube portion 21 of the collection member 20, the inspection unit 10 is arranged on a desk or the like so that the storage container 30 is on the bottom. Then, as shown in FIG. 5B, the thin tube portion 21 is covered with an air cap S, which is a sending member made of a small rubber bag or the like, on the sampling member 20, and the air cap S is pressed with a finger. The blood B inside is pushed downward, and the blood B is moved to the storage container 30. At this time, since the air in the storage container 30 escapes to the outside from the gap 26 located between the collection member 20 and the storage container 30, blood is smoothly transferred from the collection member 20 to the storage container 30. Further, since the gap 26 is provided above the outer side of the fitting portion 22, the gap 26 is not blocked by the blood flowing in the inner hole 22a of the fitting portion 22. With such an arrangement of the voids 26, it is possible to prevent the movement work of blood and the like from being impaired. The storage container 30 may contain a plasma separating agent L such as an acrylic resin gel or a polyester gel for a blood test (see FIGS. 4 and 5). In this case, the speed and accuracy of the test can be improved by separating only plasma from the blood in advance before the test.

As described above, according to the inspection unit 10 described above, the fitting portion 22 of the sampling member 20 is configured to be able to be fitted into the opening 33 at one end of the storage container 30, and the air in the storage container 30. A gap 26 is provided in the fitting region between the sampling member 20 and the storage container 30 to allow the air to escape to the outside. Therefore, after the liquid to be inspected such as blood is collected by the thin tube portion 21 of the collecting member 20 by utilizing the capillary phenomenon or the like, a predetermined force is applied to the thin tube portion 21 or the fluid to be inspected to inspect the inside of the thin tube portion 21. When the target fluid is to be moved downward where the storage container 30 is located, the air in the storage container 30 moves outward from the gap 26 of the fitting region located in the middle of the target fluid according to the movement of the target fluid. You can escape smoothly. As a result, according to the inspection unit 10, the blood B or the like of the inspection target fluid collected in the capillary portion 21 can be easily moved into the storage container 30, and the inspection target fluid after the inspection target fluid such as the blood B is collected. Can be easily transferred from the sampling member 20 to the storage container 30. As is clear from the figure, the void 26 does not need to be an excessive void because it is for allowing a part of the air (a trace amount of air) in the storage container 30 to escape to the outside. Therefore, even if such a gap 26 is provided, the influence on the fluid to be inspected can be made minor.

Further, in the inspection unit 10, the sampling member 20 is attached to the storage container 30 so that the fitting portion 22 is joined to the inner peripheral portion of the opening 33 of the storage container 30. Therefore, it becomes easy to provide a gap 26 located in the fitting region between the collecting member 20 and the storage container 30, and since the fitting portion is not arranged on the outer peripheral side of the storage container 30, the lid 32 is attached to the container body 31. It becomes easy to provide a connecting member 34 for connecting to the outer periphery of the container body 31.

Further, in the inspection unit 10, the sampling member 20 further has a flange portion 23 between the thin tube portion 21 and the fitting portion 22, and a plurality of protrusions 24 on the lower surface 23a of the flange portion 23 on the fitting portion 22 side. Is provided, and the gap 26 is defined by the protrusion 24. In this way, by providing the member (projection 24, rib 25, etc.) that defines the gap 26 on the collection member 20 (fitting portion 22) side, the portion that fits with the storage container 30 side, particularly the fitting portion 22 (the fitting portion 22). The inner peripheral shape of the opening 33) can be a simple or flat surface. Therefore, for example, when performing a test such as self-collection of blood, the storage container 30 after storing the test solution needs to be sent to the testing institution after the lid 32 is fitted into the opening 33 and tightly sealed (Fig. 4 (b)), as described above, since the opening 33 side of the storage container 30 can be formed into a smooth (flat surface) shape, the sealing property of the storage container 30 by the lid 32 can be easily improved.

Further, in the inspection unit 10, the inner hole 21a of the thin tube portion 21 extends in a tapered shape from the tip end 21b of the sampling member 20 toward the base end 21c. The sampling member 20 of the inspection unit 10 described above can be designed on the assumption that the fluid to be inspected enters the inner hole 21a of the capillary portion 21 by utilizing the so-called capillary phenomenon, but the sampling member 20 on the base end 21c (container container) side. By forming the inner diameter so as to be wider than the tip 21b side, when a predetermined force is applied to the capillary portion 21 and the fluid to be inspected, the fluid to be inspected in the capillary portion 21 is lowered due to gravity or the like. It becomes easy to move to the storage container 30. More specifically, by increasing the inner diameter of the inner hole on the base end 21c side of the capillary portion 21, the force due to the capillary phenomenon in that region is weakened, and the collected fluid to be inspected is moved to the storage container 30 side. It becomes possible to make it easy. As described above, according to the above configuration, it is possible to more easily transfer the test target fluid from the collection member 20 to the storage container 30 after collecting the test target fluid such as blood. In this case, it is preferable that the inner diameter of the inner hole 21a of the thin tube portion 21 on the base end 21c side is twice or more the inner diameter on the tip end 21b side from the viewpoint of ease of transfer.
