Description

[Technical Field]

[0001] The present invention relates to a testing device, and more particularly to a technique for easily detecting infection with an infectious disease. [Background technology]

[0002] Currently, the most common way to prevent the spread of infectious diseases that spread from person to person is to prevent multiple people from being in a closed room and to take temperatures at the entrance to the premises. However, temperature measurement and other methods have low accuracy in determining whether or not a person is infected with an infectious disease, and a more accurate method of identification is needed.

[0003] Therefore, a technology has now been developed that allows for easy identification of infectious disease infection while reducing the labor required for the subject by collecting saliva from a person (subject) who may be infected due to fever, fatigue, etc. in a saliva preservation kit (Patent Document 1), and then sending the kit to a designated testing institution for testing. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2017-194324 Summary of the Invention [Problem to be solved by the invention]

[0005] However, collecting saliva in a saliva preservation kit as described above and sending the kit to a designated testing institution for testing requires effort and time from the time the saliva is collected to determining whether or not the person is infected with an infectious disease, so there is room for further improvement.

[0006] The present invention has been made in consideration of such problems, and its purpose is to provide a testing device with a simple configuration that can determine whether or not a person is infected with an infectious disease. [Means for solving the problem]

[0007] In order to achieve the above object, the testing device of the present invention comprises a rod-shaped urine collection unit for collecting urine from a subject, a rod-shaped protective cap in which at least a portion of the urine collection unit is housed, and a test tank unit in which at least a portion of the protective cap is housed, the urine collection unit having a urine holding portion at one end for holding the urine of the subject and a convex portion formed at the tip of the urine holding portion, the protective cap having a tubular portion for housing the urine holding portion and the convex portion, and a stopper portion extending radially outward from the tubular portion, the test tank unit having an insertion portion through which the urine holding portion, the convex portion, and the protective cap can pass, and a stopper portion formed at one end of the insertion portion. the protective cap has an opening end formed at an end opposite to the opening end, a tank portion for storing a predetermined test liquid, and a thin film separating the tank portion from the insertion portion, wherein at least a portion of the stopper portion of the protective cap extends beyond the inner diameter of the opening end of the test tank unit and is formed in a position where the thin film of the test tank unit and the protective cap are separated by a predetermined distance when the stopper portion abuts against the opening end, the thin film of the test tank unit is formed to be breakable when the convex portion of the urine collection unit is pressed, and the urine retention portion is arranged in a position where it can be inserted into the tank portion beyond the thin film of the test tank unit. [Effects of the Invention]

[0008] According to the testing device of the present invention, at least a portion of the stopper portion of the protective cap extends beyond the inner diameter of the opening end of the test tank unit, preventing the protective cap from coming into contact with the thin membrane of the test tank unit. Furthermore, the thin membrane of the test tank unit is formed to be rupturable when the convex portion of the urine collection unit is pressed, preventing leakage of the specified test liquid stored in the tank unit and allowing the device to be easily opened by pressing the convex portion of the urine collection unit. Furthermore, the urine retention portion is positioned so that it can be inserted into the tank unit beyond the thin membrane of the test tank unit, allowing the urine retention portion to be immersed in the specified test liquid stored in the tank unit while breaking the thin membrane of the test tank unit. This simple configuration makes it possible to determine whether or not a person is infected with an infectious disease. [Brief explanation of the drawings]

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1, there is shown a perspective view of a test device 1. The test device 1 is an instrument that uses urine from a test subject to determine whether the test subject is infected with an infectious disease (hereinafter referred to as infection determination). The test device 1 comprises a urine collection unit 3, a protective cap 5, and a test tank unit 7.

[0011] 2 shows an exploded view of the test device 1. The urine collection unit 3 is an instrument that can hold the urine of a subject and display an infection determination. Specifically, the urine collection unit 3 has a hollow tube portion 11, a urine holding portion 13, and a display portion 15.

[0012] The hollow tube portion 11 is made of a transparent resin. A tapered portion 11a with a relatively small diameter is formed on one longitudinal side (the lower side as viewed in FIG. 2) of the hollow tube portion 11. The tapered portion 11a of the hollow tube portion 11 has a flow path 11b formed therein that can absorb a test liquid 37 (described later) by capillary action. The urine retention portion 13 is a spongy body provided at the tip of the tapered portion 11a. The urine retention portion 13 can absorb and retain urine from the subject and the test liquid 37 (described later). The urine retention portion 13 also has a protrusion 13a that protrudes from the tip. The protrusion 13a can pierce a thin film 35 (described later). The display portion 15 is capable of displaying the results of the infection determination.

[0013] Meanwhile, a square pillar section 11b, which is formed to have a quadrangle (polygon) shape when viewed from the longitudinal direction, is formed at the end opposite to the tapered section 11a of the hollow tubular section 11. This enables the square pillar section 11b to prevent the urine collection unit 3 from rolling in the circumferential direction around the longitudinal direction of the hollow tubular section 11 as an axis.

[0014] The protective cap 5 is a resin cap member whose cylindrical portion 5a can accommodate the tapered portion 11a of the hollow tube portion 11. The protective cap 5 is formed with a stopper portion 21 extending radially from approximately the center in the longitudinal direction.

[0015] The test tank unit 7 is a tank unit into which the urine collection unit 3 and protective cap 5 can be inserted and into which the test liquid 37 can be stored. The test tank unit 7 has a tank section 31, an insertion section 33, and a thin film 35. The tank section 31 is a tank that stores the test liquid 37. The tank section 31 is formed to be quadrilateral (polygonal) when viewed from the longitudinal direction. This allows the test tank unit 7 to be prevented from rolling in the circumferential direction around the longitudinal direction as an axis by the tank section 31.

[0016] The insertion portion 33 is a hollow tube extending in the longitudinal direction. The lower side of the protective cap 5 in the longitudinal direction can be inserted into this insertion portion 33. The inner diameter of the open end 33a of the insertion portion 33 is smaller than the outer diameter of the stopper portion 21 of the protective cap 5. The thin film 35 is a thin film made of, for example, aluminum, that separates the tank portion 31 and the insertion portion 33. When the protective cap 5 is inserted into the insertion portion 33, the thin film 35 is disposed at a position spaced a predetermined distance from the protective cap 5. The thin film 35 may be made of a resin material, similar to the tank portion 31, or may be formed to extend from the tank portion 31.

[0017] Here, we will explain how the test device 1 according to the present invention is stored. Before use, the tapered portion 11a of the urine collection unit 3 is inserted into the protective cap 5, and the protective cap 5 is inserted into the insertion portion 33 of the test tank unit 7. By arranging the test device 1 in this manner, the tapered portion 11a of the urine collection unit 3 is protected by the protective cap 5, while preventing the tapered portion 11a from coming into contact with the thin film 35 of the test tank unit 7. Therefore, the test device 1 can be stored in a relatively compact manner, while preventing damage during transportation, etc. 3 to 6, there are shown explanatory diagrams for explaining how to use the inspection device 1. Hereinafter, how to use the inspection device 1 according to the present invention will be described.

[0018] First, the subject, who is the test subject, pulls the urine collection unit 3 together with the protective cap 5 longitudinally out of the test tank unit 7 (Fig. 3). Next, the subject pulls the urine collection unit 3 longitudinally out of the protective cap 5 (Fig. 4). Next, the subject allows urine to penetrate the urine retention portion 13 of the urine collection unit 3 (not shown). Specifically, the subject collects urine by pouring it onto the urine retention portion 13 of the urine collection unit 3.

[0019] The subject then inserts the urine retention portion 13 into the insertion portion 33 and presses it, causing the convex portions 13a to break the thin film 35 (FIGS. 5 and 6). When the convex portions 13a break the thin film 35, the urine retention portion 13 becomes immersed in the test liquid 37 in the tank portion 31. When the urine retention portion 13 is immersed in the test liquid 37 in the tank portion 31 in this way, the test liquid 37 combines with the subject's urine, moves through the tapered portion 11a by capillary action, for example, and permeates the display portion 15.

[0020] The test solution 37 is a liquid that undergoes a chemical reaction when the subject is infected with a specific infectious disease. The display unit 15 is paper containing an indicator that chemically reacts with the test solution 37 to display a line 15a at a predetermined location. Specifically, the test solution 37 contains gold colloid particles bound to an anti-SARS-CoV-2 human monoclonal antibody, and the display unit 15 has an anti-SARS-CoV-2 mouse monoclonal antibody immobilized thereon. Therefore, in the test device 1, the subject's urine reacts with the gold colloid particles bound to the anti-SARS-CoV-2 human monoclonal antibody in the test solution 37 to form a complex, which is then captured by the anti-SARS-CoV-2 mouse monoclonal antibody immobilized on the display unit 15, forming a line 15a on the display unit 15.

[0021] As a result, if the subject is infected with a specific infectious disease, the testing device 1 can display line 15a at a first location to indicate that the subject is positive, and if the subject is not infected with the specific infectious disease, the testing device 1 can display line 15a at a second location (for example, a position longitudinally inward from the first location) to indicate that the subject is negative.

[0022] As explained above, the testing device according to the present invention comprises a rod-shaped urine collection unit 3 for collecting urine from a subject, a rod-shaped protective cap 5 in which at least a portion of the urine collection unit 3 is housed, and a test tank unit 7 in which at least a portion of the protective cap 5 is housed; the urine collection unit 3 has a urine retention portion 13 for holding the urine of the subject at one end and a convex portion 13a formed at the tip of the urine retention portion 13; the protective cap 5 has a tubular portion 5a that houses the urine retention portion 13 and the convex portion 13a, and a stopper portion 21 that extends radially outward from the tubular portion 5a; and the test tank unit 7 has an insertion portion 33 through which the urine retention portion 13, the convex portion 13a, and the protective cap 5 can pass, and a stopper portion 21 that extends radially outward from the tubular portion 5a. The protective cap 5 has an opening end 33a formed at one end, a tank section 31 formed at the end opposite the opening end 33a and for storing test liquid 37, and a thin film 35 separating the tank section 31 and the insertion section 33, and at least a portion of the stopper section 21 of the protective cap 5 extends beyond the inner diameter of the opening end 33a of the test tank unit 7 and is formed in a position where the thin film 35 of the test tank unit 7 and the protective cap 5 are separated by a predetermined distance when abutting against the opening end 33a, the thin film 35 of the test tank unit 7 is formed so as to be breakable when the convex section 13a of the urine collection unit 3 is pressed, and the urine retention section 13 is arranged in a position where it can be inserted into the tank section 31 beyond the thin film 35 of the test tank unit 7.

[0023] Therefore, at least a portion of the stopper portion 21 of the protective cap 5 extends beyond the inner diameter of the opening end 33a of the test tank unit 7, preventing the protective cap 5 from coming into contact with the thin film 35 of the test tank unit 7. Furthermore, the thin film 35 of the test tank unit 7 is formed to be rupturable when the convex portion 13a of the urine collection unit 3 is pressed, thereby preventing leakage of the test liquid 37 stored in the tank portion 31 and allowing the urine retention portion 13 to be easily opened by pressing the convex portion 13a of the urine collection unit 3. Furthermore, because the urine retention portion 13 is positioned so that it can be inserted into the tank portion 31 beyond the thin film 35 of the test tank unit 7, the thin film 35 of the test tank unit 7 can be ruptured and the urine retention portion 13 can be immersed in the test liquid 37 stored in the tank portion 31.

[0024] Furthermore, at least a portion of the urine collection unit 3 and the testing tank unit 7 is formed to have a polygonal shape when viewed from the longitudinal direction, which prevents the urine collection unit 3 and the testing tank unit 7 from rolling circumferentially around the longitudinal axis. In particular, since the test subject's urine is handled, by preventing the urine collection unit 3 and the test tank unit 7 from rolling in a circumferential direction around the longitudinal axis, it is possible to prevent the test device 1 from rolling after collecting urine and scattering the test subject's urine around.

[0025] This concludes the explanation of the inspection device according to the present invention, but the present invention is not limited to the above-described embodiment and can be modified within the scope of the gist of the invention. For example, in this embodiment, the thin film 35 is an aluminum thin film, but it may be formed of a resin material like the tank portion 31, or may be formed to extend from the tank portion 31.

[0026] Furthermore, in this embodiment, the urine retention portion 13 is formed as a convex portion 13a protruding from the tip, but it may also be formed as a cylinder cut at a plane inclined at a predetermined angle relative to the radial direction, as long as it can penetrate and break the thin film 35.

[0027] In addition, in this embodiment, the rectangular column portion 11b and the tank portion 31 are formed to be rectangular when viewed from the longitudinal direction, but it is sufficient that at least a portion of them is formed to be rectangular, and they may be polygonal, such as triangular.

[0028] In addition, in this embodiment, a flow path 11b capable of sucking up the test liquid 37 by capillary action is formed inside the tapered portion 11a of the hollow tube portion 11, but the tapered portion 11a may be inserted into the tank portion 31 to reduce the space in the tank portion 31 that can store the test liquid 37, causing the test liquid 37 to flow into the hollow tube portion 11.
