Description

Technical Field

[0001] The present invention relates to the technical field of urine detection, and in particular to a urine detection device and a detection method thereof. Background Art

[0002] The law enforcement and detection work of drug prohibition and detoxification usually involves collecting urine from the person being tested - testing the urine through a "urine test plate" - observing the test line - further processing the urine of the person being tested: If the test result is positive or the test result is vague, photos must be taken for evidence and the urine sample must be divided into A / B packages and then sent to the laboratory for analysis using instruments such as GC / MS; If the test result is negative, it will be handled after verification.

[0003] The rapid urine testing devices used by drug enforcement personnel mainly include dropper-type urine rapid testing plates (see attached for details). Figure 7-1 ), immersion urine rapid test plate (see Figure 7-2 for details) and direct detection urine rapid test cup (see Figure Figure 7-3 ), because of its high cost, most areas mainly use immersion and dropper types, and there are still great problems in actual operation, such as: the urine container is a soft and thin (thickness of about 0.1mm) transparent cup made of plastic material, which is not independently packaged. After opening the packaging bag, it is exposed to the air for a long time, which is easy to be contaminated, and it is easy to break and spill when holding urine; the immersion urine test board must pay attention to the urine sample liquid level must be between the minimum scale and the maximum scale, and it cannot exceed the red line, which is very inconvenient to operate; when using the dropper type urine test board, the collected urine must be transferred before testing during the test; if the collected test sample is positive after on-site testing, it should be stored in two sample-specific equipment A and B and numbered, and the urine should be transferred again during the A / B packaging process, which is extremely inconvenient. In summary, in order to reduce the cumbersome steps in the rapid urine test process and facilitate the urine test, a urine detection device and a detection method thereof are urgently needed to solve the above problems.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-1 0. An embodiment provided by the present invention:

[0043] A urine detection device and a detection method thereof, comprising:

[0044] The device body 1 includes a cup body A 110 and a cup body B 111. The interior of the cup body A 110 and the cup body B 111 is divided into a first, a second and a third area from top to bottom, which are a liquid collection area, a drainage and gas guide area and a storage function area (see the attached figure for details). Figure 4 );

[0045] The funnel 113 is two in number and is respectively embedded in the second section of the A cup body 110 and the B cup body 111 to connect the first and third sections. The interiors of the two funnels 113 are both connected to a second one-way valve 115 (see Figure 5), the second intervals of the A cup body 110 and the B cup body 111 are both connected to the first one-way valve 114, connecting the second and third intervals, the first intervals of the A cup body 110 and the B cup body 111 are both provided with through holes, connecting the first interval and the third interval, and the inner wall of the third interval of the A cup body 110 is connected to the detection module 116 (see the attached Figure 1 and 4 ), considering the manufacturing cost of the device, the detection module 116 has a high cost, and the urine samples collected in the A cup body 110 and the B cup body 111 are consistent, so there is no need to set up multiple detection modules 116. The present invention utilizes the combination of the urine collection vessel, the urine detection device and the A / B bottle type to improve the shortcomings of the existing urine detection device, so that the function of the urine rapid detection device is maximized. Compared with the actual operation of the prior art, on the one hand, there is no need to worry about the urine container being contaminated by long-term exposure to the air, and on the other hand, it does not need to be transferred multiple times, which is more convenient to use; thirdly, the turbid urine sample will automatically pass through the second one-way valve 115 to filter, and there is no need to place the urine sample for a period of time and then take out the supernatant for use, and there is no need to worry about affecting the detection; finally, there is no need to pay attention to the urine sample liquid level must be between the minimum scale and the maximum scale, and there is no need to worry about exceeding the detection red line, so that the device also has the characteristics of simple and sensitive operation, direct and rapid results, and reducing the degree of oxidation of the detection module 116 and the air.

[0046] Furthermore, the A cup body 110 and the B cup body 111 are simply fixed together by glue (see the attached Figure 3 ), which makes it easy to disassemble the device into A / B bottles for use.

[0047] Furthermore, the through holes of the A cup body 110 and the B cup body 111 are both connected with a conduit 117, and the height of the conduit 117 is flush with the openings of the A cup body 110 and the B cup body 111 (see the attached Figure 3 and 4 ), use the conduit 117 to raise the exhaust height to prevent urine from entering the second interval.

[0048] Furthermore, the A cup body 110 and the B cup body 111 are both provided with a groove 118 (see the attached Figure 1 and 3 ), used for diverting the liquid into the A cup body 110 and the B cup body 111.

[0049] Furthermore, the tops of the A cup body 110 and the B cup body 111 are movably connected with a cup cover 112, the outer side of the cup cover 112 has an anti-slip thread, and the edge of the cup cover 112 has a corresponding sealing strip (see the attached Figure 1 , 2 and 3), performing dustproof and sealing treatment on the A cup body 110 and the B cup body 111 when not in use.

[0050] Furthermore, cup body A 110, cup body B 111 and cup cover 112 are made of transparent PP plastic. The PP plastic material has the characteristics of reliable quality, not easy to deform, high temperature resistance, strong corrosion resistance, etc., and the PP plastic material can be made transparent, which is convenient for observing the test results.

[0051] Furthermore, a protrusion 119 is connected to the inner surface of the cup cover 112, and the protrusion 119 and the groove 118 are designed in a hook-shaped trapezoid. The bottom end of the cup cover 112 and the top ends of the cup body A 110 and the cup body B 111 are designed in a hook-shaped design. The side joints of the cup body A 110 and the cup body B 111 and the independent partition layer in the middle of the cup cover 112 are in a symmetrical trapezoid. The use of plastic component art design is to make the plastic component fit better and have better airtightness.

[0052] Furthermore, the first check valve 114 and the second check valve 115 are both zero hydraulic check valves, which have multiple grooves inside (see attached Figure 6 ), which is convenient for the use of the device for exhaust and liquid conduction, and whether the urine can smoothly reach the third interval, the selection of the first one-way valve 114 and the second one-way valve 115 is very important. When the elastic stiffness coefficient of the one-way valve spring is too large, it will cause the detected liquid to flow into the liquid storage chamber with a small amount of inflow or the liquid cannot flow in, which will affect the reading of the test result. If the elastic stiffness coefficient of the one-way valve spring in the one-way valve drainage chamber is too small, it will be unfavorable for the valve check port cover to slowly rise under the action of the spring, so that the valve is closed, and the valve core is stationary in the flow field to achieve the effect of tightly closing and intercepting the flow, and the sealing effect of the A cup body 110 and the B cup body 111 will be greatly reduced (the above-mentioned elastic stiffness coefficient correlation of the one-way valve spring, see for details). Figures 8-1 to 8-3 ).

[0053] Furthermore, the detection module 116 uses the test module of the direct-detection "urine test cup". During the detection process, there is no need to consider the height of the urine sample liquid level. The detection module 116 uses the cellulose hydrochloride membrane, PVC and other materials used in the current urine test board to make antigen-antibody colloidal gold, and uses the monoclonal antibody labeled with colloidal gold as the indicator marker. The antigen-BSA conjugate and the polyclonal antibody are coated at the detection line and the control line on the hydrochloric acid cellulose membrane respectively. During the detection, the urine sample flows through the sample pad to the quenching antibody binding pad, and chromatographs under the capillary effect. If the concentration of the substance to be tested (antigen) in the urine sample is lower than the detection network value, the monoclonal antibody containing the marker cannot be completely combined with the substance to be tested. The unbound gold-labeled antibody combines with the antigen-BSA conjugate fixed at the detection line during the chromatography process, and the background fluorescence at the T line decreases, so that a purple-red strip appears on the detection line T. The detection module 116 mainly relies on the detection threshold of the amount of toxins. When a person does not take drugs, the urine of the person will not reach this detection threshold. The initial detection threshold of urine for different types of drugs is also different (see the attached Figure 9-1 ).

[0054] A detection method of a urine detection device, comprising:

[0055] S1, directly give the device to the person to be tested to collect urine, and open the cup cover 112;

[0056] S2, pouring urine toward the two grooves 118, so that the urine enters the first interval of the A cup body 110 and the B cup body 111;

[0057] S3, urine flows along the funnel 113 and the funnel 113 into the third section of the A cup body 110 and the B cup body 111, and the gas in the third section is squeezed by the urine and discharged along the first one-way valve 114 to the second section of the A cup body 110 and the B cup body 111, and is discharged from the second section along the conduit 117 (see the attached figure for details). Figure 10-1 and 10-2 , in 10-2, the black arrow represents urine and the white arrow represents gas);

[0058] S4, urine flows down the cup body 110 and penetrates the detection module 116;

[0059] S5, wait for 5-8 minutes, observe the color change of the detection module 116 to obtain the result.

[0060] Working principle: Compared with cup body A 110 and cup body B 111, the only missing part is the detection module 116. For the convenience of introduction, cup body B 111 is taken as an example. The collected urine first passes through the first interval and then enters the third interval through the funnel 113. When the urine passes through the funnel 113 and is ready to enter the third interval, the check port of the first one-way valve 114 in the second interval is acted upon by the liquid pressure of the drainage trough at the second one-way valve 115 and the gas pressure in the third interval. When the pressure of the two is greater than the spring force of the internal spring of the first one-way valve 114, the valve cover of the first one-way valve 114 gradually opens, and the gas in the third interval is led out to the second interval and discharged through the conduit 117 connected to the second interval, so that the urine in the first interval can flow in the forward direction.

[0061] When the liquid flows, the urine liquid in the funnel 113 and the second one-way valve 115 gradually decreases, and the pressure of the liquid gradually decreases, so that the liquid pressure in the drainage groove of the second one-way valve 115 and the gas pressure in the third interval are balanced with the force of the valve cover of the second one-way valve 115 and the force inside the valve core.

[0062] When the liquid continues to decrease, the liquid pressure in the drainage groove of the second one-way valve 115 and the gas pressure in the third interval act on the valve cover of the second one-way valve 115 less than the force inside the valve core. The valve check port cover will slowly rise under the action of the spring, so that the valve is closed and the valve core remains stationary in the flow field to achieve the effect of reverse interception, thereby completing the packaging of urine into cup body A 110 and cup body B 111, so that the urine is effectively sealed and stored in the two third intervals.

[0063] During the urine storage process, the urine sample flowing into the third compartment of the B cup body 111 will slowly penetrate into the detection module 116 through the small holes on the bottom of the third compartment. If the person being tested has taken drugs of the type marked with colloidal gold, the urine sample will compete with the drug monoclonal antibody labeled with colloidal gold containing complete drug antigens in the rapid detection area, and the colloidal gold of the monoclonal antibody will compete with each other for binding, and a positive result of drug use will be detected.

[0064] In addition, there are three situations for reading test results (see Figure 9-2 ):

[0065] If purple-red strips appear in both the test area T and the quality control area C, the result is negative, indicating that no drugs have been taken.

[0066] If a purple-red band appears in the test area T and no purple-red band appears in the quality control area C, it is positive and is judged as drug use.

[0067] If a purple-red band appears in the test area T, but there is no purple-red band in the quality control area C, or if there is no purple-red band in both the test area T and the quality control area C, the test is invalid.

[0068] Note that when a positive result occurs, one red line appears in the quality control area and the other in the test area. The two lines do not need to be the same shade, and the red line in the test area will change. As long as a red line is visible in the test area (whether lighter, darker, or equal to the line in the quality control area), it should be considered a negative result.

[0069] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
