Description

[Technical Field]

[0001] The present invention relates to a urine test kit. [Background technology]

[0002] Generally, urine tests are essential tests, accounting for approximately 30% of the total testing volume in most hospitals, and are used as a diagnostic method to detect the overall condition and lesions by examining the components of urine.

[0003] A commonly used method for such urine testing is to contact a test stick with a test paper attached to it with the subject's urine and test the urine based on the color change of the test paper. That is, the tester applies urine directly to the test stick or collects urine using a container such as a paper cup and then contacts the test stick with the urine.

[0004] However, existing urine testing methods have the risk of exposing the tester and subject to secondary infection due to the sample, and are inconvenient in that the tester must directly apply urine to a urine test strip.

[0005] Furthermore, there is a problem in that the accuracy of the test is low because the time between urine collection and testing varies.

[0006] Therefore, prior art Korean Patent Publication No. 10-1904037 relates to a urine test kit and test device, in which urine collected inside a container rises along the urine flow path due to capillary action caused by the urine flow path and is guided to a test strip, so that the color change of the strip can be confirmed immediately after the urine is collected. However, if a long time passes between urine collection and testing, the strip changes color to a different color than immediately after the test, making the test inaccurate. This causes inconvenience to the tester, who must perform the test immediately after collecting the urine. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] The present invention will now be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and practice the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. In the drawings, parts that are not relevant to the description are omitted in order to clearly explain the present invention, and similar parts are designated by similar reference numerals throughout the specification.

[0016] Throughout the specification, when a part is said to be "connected" to another part, this includes not only "directly connected" but also "electrically connected" with another element sandwiched therebetween. Furthermore, when a part is said to "comprise" a certain component, this does not mean that it can further include other components, but does not exclude other components, unless otherwise specified.

[0017] Hereinafter, specific details for carrying out the present invention will be described with reference to the accompanying drawings.

[0018] Fig. 1 is a diagram showing a urine test kit according to one embodiment of the present invention. Fig. 2 is a diagram showing a strip paper guide connected to an air pump according to one embodiment of the present invention. Fig. 3 is a diagram showing the urine test kit of Fig. 1 from another side. Fig. 4 is an exemplary diagram showing a connecting hose of a urine test kit according to another embodiment of the present invention passing through a container connecting hole.

[0019] First, referring to FIG. 1, a urine test kit 100 according to one embodiment of the present invention may include a container 110, a paper strip guide 120, and an air pump .

[0020] The container 110 may contain urine, but is not limited to this, and the container 110 may contain various types of liquid specimens that can cause the paper strip 121 to change color.

[0021] Here, the paper strip 121 may be a test paper that changes color when exposed to a liquid sample such as urine. In one embodiment, the paper strip 121 may be embodied as litmus paper that changes color when exposed to urine, allowing a user to visually check the condition of the urine through the discolored litmus paper. For example, the paper strip 121 may be a test paper that can be used to test for diseases such as occult blood, proteinuria, and glucose through its discoloration caused by urine.

[0022] At least a portion of the container 110 may be made of a transparent or translucent material. For example, the container 110 may be made of a transparent plastic material. This allows the user to check the amount of urine remaining inside the container 110.

[0023] Although the container 110 is illustrated as a hollow cylindrical structure in which the diameter of the upper outer periphery is larger than the diameter of the lower portion, it may also have a cylindrical structure in which the diameter of the upper outer periphery is the same as the diameter of the lower portion. However, the container 110 is not limited thereto, and may have various shapes, such as a polygonal structure in which the diameter of the upper outer periphery or the diameter of the lower portion is rectangular or pentagonal.

[0024] 2, the paper strip guide 120 may include a groove 125 and a paper strip 121 disposed in the groove 125. Specifically, the paper strip guide 120 may have a groove 125 formed therein, and the groove 125 formed in the paper strip guide 120 may include a paper strip insertion groove 123 into which the paper strip 121 can be inserted.

[0025] At this time, the grooves 125 formed in the paper strip guide 120 may be formed in a plurality of grooves at the bottom of the paper strip guide 120, and the plurality of grooves 125 may be gathered together at the top of the paper strip guide 120. As a result, a paper strip insertion groove 123 may be formed in each of the plurality of grooves 125 formed at the bottom of the paper strip guide 120.

[0026] As described above, the paper strip 121 may be a test paper that can test for diseases related to occult blood, proteinuria, glucose, etc. by detecting discoloration due to urine. Accordingly, the paper strip 121 required for testing each item can be inserted into each of the paper strip insertion grooves 123 in a sequential order in the multiple grooves formed in the lower part of the paper strip guide 120.

[0027] The paper strip 121 may also be positioned a predetermined distance from the bottom end of the lower portion of the paper strip guide 120. In this case, the paper strip insertion grooves 123 may be formed a predetermined distance from the bottom end of each of the plurality of grooves 125 formed in the lower portion of the paper strip guide 120, and the paper strip 121 may be inserted into the paper strip insertion grooves 123.

[0028] The arrangement of the grooves 125 formed in the paper strip guide 120 may be modified in various ways, as will be explained with reference to FIG.

[0029] 1, the strip paper guide 120 may be attached to one surface of the container 110, and a channel 126 may be formed between a groove 125 of the strip paper guide 120 and one surface of the container 110. In other words, the strip paper guide 120 may be embodied as a sheet attached to one surface of the container, having a channel formed therein through which a liquid sample moves, and having at least one strip paper disposed in at least a portion of the channel that changes color due to the liquid sample.

[0030] Specifically, when the paper strip guide 120 of FIG. 2 is attached to the inner surface of the container 110 in the circumferential direction, a flow path 126 can be formed between the groove 125 of the paper strip guide 120 and one surface of the container 110.

[0031] In one embodiment, the paper strip guide 120 may be attached to the inner surface of the container 110 in the circumferential direction, a predetermined distance away from the bottom of the container 110. In this case, the paper strip guide 120 may be spaced a predetermined distance from the bottom of the container 110 so as not to hinder the urine 10 contained in the container 110 from flowing into the lower end 129 of the lower flow path of the paper strip guide 120. As a result, since the paper strip guide 120 is spaced a predetermined distance from the bottom of the container 110, the urine 10 contained in the container 110 can stably flow into the paper strip guide 120 through the flow path 126 formed in the paper strip guide 120.

[0032] The flow path 126 formed by attaching the paper strip guide 120 to one side of the container 110 may include a lower flow path and an upper flow path. The lower flow path may be a flow path formed by a plurality of grooves formed in the lower part of the paper strip guide 120, and the upper flow path may be a flow path formed by a groove formed in the upper part of the paper strip guide 120 in such a way that the plurality of grooves are gathered into one.

[0033] The paper strip guide 120 may be connected to an air pump 130 to allow urine to flow into the paper strip 121. The air pump 130 may be made of an elastic material and be deformable, and may be embodied in a form containing air therein. The air pump 130 may be circular as shown in FIGS. 1 and 2, but is not limited thereto, and may be embodied in various shapes such as a polygon, heart, star, etc.

[0034] The air pump 130 may be configured such that a pressure difference is generated between the inside and outside of the air pump 130 by a pumping operation in which the air pump 130 is pressed to contract and then expanded, causing the urine 10 to flow into the paper strip 121 through the flow path 126 of the paper strip guide 120. In other words, Boyle's law may be utilized, in which as the volume inside the air pump 130 increases, the pressure decreases and liquid flows in from atmospheric pressure. This allows the user to check the paper strip 121 for discoloration due to urine by pressing the air pump 130 to perform a pumping operation.

[0035] In this way, the amount of urine flowing in due to pressure applied by the air pump 130 can be determined according to the volume of the air pump 130 and the change in volume due to pressure applied. Therefore, the air pump 130 may be embodied in various volumes or made of various elastic materials, taking this into consideration so that the paper strip 121 can adequately respond to the amount of urine moved by one pressure application.

[0036] In one embodiment, the air pump 130 may be configured as a pressurizing unit that causes the liquid sample to flow into the paper strip 121. When the pressurizing unit is pressurized, the air inside the pressurizing unit is discharged to the outside, and when the pressurizing unit is released, the liquid sample can flow into the paper strip 121 through the flow path 126 due to the pressure difference between the inside and outside of the pressurizing unit.

[0037] Meanwhile, the air pump 130 and the paper strip guide 120 are shown as being integrally connected via a connecting hose 140, but this is merely an example, and the air pump 130 and the paper strip guide 120 may be connected in various ways depending on the embodiment to which the present invention is applied. In this case, the connecting hose 140 may be connected to the air pump 130 and serve as a passage for transmitting air.

[0038] In one example, the upper end 128 of the upper flow passage of the paper strip guide 120 may be connected to the lower end of the connecting hose 140 so as to be able to communicate with the interior of the connecting hose 140. For example, the connecting hose 140 may be inserted into the upper flow passage of the paper strip guide 120 and mated together. Alternatively, the connecting hose 140 may be attached to and connected to the upper end 128 of the upper flow passage of the paper strip guide 120. Alternatively, the connecting hose 140 may be integral with the upper end 128 of the upper flow passage of the paper strip guide 120.

[0039] Also, the lower end of the air pump 130 may be coupled to the upper end of the connecting hose 140 so as to be able to communicate with the interior of the connecting hose 140. For example, the lower end of the air pump 130 may be fixed integrally with the connecting hose 140 or may be a detachable separate type.

[0040] By connecting the air pump 130 and the paper strip guide 120 in this manner, the inside of the channel 126 formed in the paper strip guide 120 can be sealed. Therefore, when no pressure is applied to the air pump 130, urine can be prevented from flowing into the channel 126 even if it is present in the container 110. However, due to adhesive force caused by capillary action, urine in the container 110 can flow up the wall of the channel 126 and rise to a certain height.

[0041] Therefore, as described above, the paper strip 121 may be positioned at a height that is a predetermined distance away from the lower end 129 of the lower flow path of the paper strip guide 120. In this case, the paper strip 121 may be positioned at a predetermined distance from the lower end 129 of the lower flow path of the paper strip guide 120 so that when urine is stored in the container 110, even if urine in the container 110 flows to a predetermined height through the lower end of the flow path 126 of the paper strip guide 120 due to capillary action, the urine does not rise to the height at which the paper strip 121 is positioned.

[0042] In other words, by positioning the paper strip 121 a predetermined distance from the lower end 129 of the lower flow path of the paper strip guide 120, even if urine stored in the container 110 rises a predetermined height through the flow path 126 formed in the paper strip guide 120 due to capillary action, the urine can be prevented from coming into contact with the paper strip 121.

[0043] Therefore, by applying pressure to and releasing pressure from the air pump 130, the volume inside the air pump 130 decreases or increases, and a pressure change occurs inside the connecting hose 140 and the flow path 126 of the paper strip guide 120, thereby allowing urine to flow in and out. In this case, the air pump 130 is preferably made of a soft material so that it can be elastically deformed by the user's pressure, but is not limited to this.

[0044] When the air pump 130 made of an elastic material contracts due to external pressure, the air inside the air pump 130 passes through the inside of the connecting hose 140 and moves to the outside via the flow path 126 of the paper strip guide 120 .

[0045] The lid 150 may be detachably connected to the top of the container 110 to open or close the container 110. While the lid 150 is shown as being fit-fitted to the top of the container 110, this is merely an example, and the lid 150 and the container 110 may be connected in various ways depending on the embodiment to which the present invention is applied. For example, the lid 150 and the container 110 may be screwed together.

[0046] 1 and 3, the lid 150 may have a lid connection hole 151 formed on the top surface thereof, and a connection hose 140 connecting the air pump 130 and the paper strip guide 120 may pass through the lid connection hole 151. Specifically, the paper strip guide 120 connected to the air pump 130 via the connection hose 140 may be attached to the inner surface of the container 110 in the circumferential direction, and the lid connection hole 151 may be formed on the top surface of the lid 150, and the connection hose 140 may pass through the lid connection hole 151.

[0047] In another embodiment, as shown in FIG. 4, the urine test container 200 may have a container connection hole 211 formed on the side of the container 210, and a connection hose 240 connecting the air pump 230 and the strip paper guide 220 may pass through the container connection hole 211.

[0048] Specifically, a strip paper guide 220 connected to an air pump 230 via a connecting hose 240 may be attached to the inner surface of the container 120 in a circumferential direction to form a flow path 226, and a container connecting hole 211 may be formed on a side of the container 210, and the connecting hose 240 may pass through the container connecting hole 211. In addition, a lid 250 may be detachably attached to the top of the container 210 to open or close the container 210.

[0049] FIG. 5a is a diagram showing a urine test kit according to one embodiment before the air pump 130 is pumped, and FIG. 5b is a diagram showing a urine test kit according to one embodiment after the air pump 130 is pumped.

[0050] 5a and 5b, the paper strip guide 120 is shown transparent to show how the urine 10 contained in the container 110 flows into the paper strip 121 through the flow path 126 of the paper strip guide 120.

[0051] First, as shown in Figure 5a, the air pump 130 and the paper strip guide 120 are connected, so that the inside of the channel 126 formed in the paper strip guide 120 may be sealed. As a result, when no pressure is applied to the air pump 130, even if urine is present in the container 110, urine can be prevented from flowing into the channel 126.

[0052] However, although not shown, adhesive force may occur due to capillary action, and urine in the container 110 may rise to a predetermined height by running down the wall of the flow path 126. For this reason, the paper strip 121 may be positioned at a height that is a predetermined distance away from the bottom end of the lower flow path of the paper strip guide 120. In this case, the paper strip 121 may be positioned at a predetermined distance from the bottom end of the lower flow path of the paper strip guide 120 so that, even if urine in the container 110 flows to a predetermined height through the bottom end of the flow path 126 of the paper strip guide 120 due to capillary action while urine is being stored in the container 110, the paper strip 121 will not rise to the height at which the paper strip 121 is positioned.

[0053] In other words, by positioning the strip paper 121 a predetermined distance from the lower end of the lower flow path of the strip paper guide 120, even if the urine in the container 110 rises a predetermined height through the flow path 126 formed in the strip paper guide 120 due to capillary action while storing urine in the container 110, the urine can be prevented from coming into contact with the strip paper 121.

[0054] Meanwhile, referring to FIG. 5b, when the urine 10 contacts the lower end of the lower flow path of the strip paper guide 120 with pressure being applied to the air pump 130, if the external pressure is then removed, the pressure inside the flow path 126 of the strip paper guide 120 and the air pump 130 becomes lower than the external pressure.

[0055] Therefore, due to the pressure difference, a predetermined amount of urine moves from the lower end of the lower flow path of the strip paper guide 120 through the inside of the flow path 126 of the strip paper guide 120 to the air pump 130, and as it moves, the urine comes into contact with and reacts with the strip paper 121 inserted into the strip paper guide 120.

[0056] The urine test kit according to one embodiment of the present invention uses an air pump 130 to force the urine 10 contained in the container 110 into the strip paper 121, allowing the tester to perform the urine test at a time of their choosing after collecting the urine, thereby improving the reliability of the test.

[0057] 6a to 6g are schematic diagrams illustrating various arrangements of grooves formed in a paper strip guide according to an embodiment of the present invention.

[0058] As described above with reference to Figure 2, the paper strip guide 120 may have a plurality of grooves 125 formed at the bottom of the paper strip guide 120, and the plurality of grooves 125 may be gathered together at the top of the paper strip guide 120. As a result, a paper strip insertion groove 123 may be formed in each of the plurality of grooves formed at the bottom of the paper strip guide 120. Also, the paper strip insertion groove 123 may be formed a predetermined distance from the bottom end of each of the plurality of grooves 125 formed at the bottom of the paper strip guide 120.

[0059] 6a, the lower grooves 125 of the paper strip guide 120 may be arranged to have the maximum length in the longitudinal direction, and the upper grooves 125 may be formed to have the minimum length. In other words, the upper grooves 125 may be formed to have a length short enough to allow multiple grooves 125 formed in the lower part of the paper strip guide 120 to be gathered into one.

[0060] 6b, the outer periphery of the paper strip guide 120 may be embodied so that it is spaced a predetermined distance from the area where the groove 125 is formed. In this case, when the paper strip guide 120 is attached to the container 110, the paper strip guide 120 forms a flow path 126, and the outer periphery of the paper strip guide 120 may be spaced a suitable distance from the area where the groove 125 is formed so that urine can flow into the paper strip through the flow path.

[0061] Also, as shown in FIG. 6c, the strip paper guide 120 may be formed so that the length of the lower groove 125 is shorter than or equal to the length of the upper groove 125.

[0062] Also, as shown in FIG. 6d, the paper strip guide 120 may be embodied in such a way that the lower groove 125 is formed in a straight line from the portion where the paper strip insertion groove 123 is formed to the portion where the upper groove 125 is formed.

[0063] Alternatively, the paper strip guide 120 may be embodied in various forms as shown in FIGS. 6e to 6g.

[0064] The above description of the present invention is for illustrative purposes only, and those skilled in the art will understand that the present invention can be easily modified into other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all respects and not limiting. For example, each component described as a single component may be implemented in a distributed form, and similarly, each component described as a distributed component may be implemented in a combined form.

[0065] The scope of the present invention is indicated by the claims that follow rather than by the above detailed description, and all modifications and variations that fall within the meaning and scope of the claims and their equivalents should be interpreted as being included within the scope of the present invention.
