[0002] In the current field of medical testing, urine analysis, as a non-invasive and convenient diagnostic method, is widely used in the auxiliary diagnosis of kidney diseases, diabetes, urinary tract infections, and other diseases. However, traditional urine analyzers have obvious technical limitations, namely that each test can only analyze a single component in the urine.

[0003] This single-component testing method not only prolongs the overall testing time and increases patient waiting time, but also poses a challenge to the effective utilization of medical resources. In practice, medical staff need to take multiple samples and operate the instrument multiple times to complete a comprehensive assessment of multiple key indicators in the patient's urine. This not only increases the workload but may also affect the accuracy of the test results due to errors introduced by multiple operations.

[0004] Therefore, there is an urgent need for a urine testing instrument to solve the aforementioned problems. Utility Model Content

[0037] like Figures 1-3 As shown, this embodiment provides a urine analyzer, which includes a housing assembly 1 and a detection assembly 2. Specifically, the housing assembly 1 is provided with interconnected liquid inlet channels 121 and detection channels 122. There are multiple liquid inlet channels 121 and multiple detection channels 122, and they correspond one-to-one. Different types of dry reagent tablets are disposed in the multiple detection channels 122. The detection liquid can move through the liquid inlet channel 121 to the dry reagent tablets in the detection channel 122. The detection assembly 2 is installed in the housing assembly 1 and located on one side of the detection channel 122. The detection assembly 2 is used to detect the concentration of the analyte in the detection liquid on the dry reagent tablets.

[0038] This urine analyzer has multiple detection channels 122. The dry reagent strips in the detection channels 122 can be configured with different types depending on the type of analyte in the detection liquid. When using this urine analyzer to test urine, the detection liquid is urine, and the analyzer is placed in the detection liquid. The detection liquid moves through the inlet channel 121 to the dry reagent strips in the detection channels 122. Different analytes in the urine react with different types of dry reagent strips, and the detection component 2 detects the concentration of the analyte in the detection liquid on the dry reagent strips. This urine analyzer enables the detection of multiple analytes in urine in a single test, improving detection efficiency, reducing detection errors, and increasing detection accuracy.

[0039] Specifically, the detection component 2 includes a circuit board 21, an illumination component 22, and a microprocessor chip component 24. The circuit board 21 is installed inside the housing component 1 and located on one side of the multiple detection channels 122. The illumination component 22 is disposed on the side of the circuit board 21 near the detection channel 122 and is used to illuminate the dry reagent in the detection channel 122. The acquisition component 23 is provided with multiple color sensors 231, each corresponding to a different dry reagent. The color sensors 231 are used to collect reflected light from the dry reagent. The microprocessor chip component 24 is disposed on the circuit board 21 and electrically connected to the acquisition component 23. Each color sensor 231 corresponds to one microprocessor chip component 24. The detection liquid can move through the liquid inlet channel 121 to the dry reagent strip in the detection channel 122. Different substances to be detected in the urine react with different types of dry reagent strips, causing the dry reagent strips to change color. The intensity of the color is proportional to the concentration of the substance to be detected in the urine sample. Each dry reagent strip is irradiated by the light-emitting component 22 and produces different reflected light. The color sensor 231 receives light signals of different intensities and converts them into corresponding electrical signals. The microprocessor chip component 24 then calculates the reflectance of each substance to be detected in the urine, and then derives the concentration of the substance to be detected from the reflectance. By comparing the concentration with the range, the concentration of the substance to be detected in the detection liquid on the dry reagent strip is realized.

[0040] In this embodiment, the color sensor 231 is a monochrome sensor. Since multiple color sensors 231 correspond to one microprocessor chip component 24, the data of multiple color sensors 231 are processed by one microprocessor chip component 24, which reduces the number of microprocessor chip components 24 and thus reduces the production cost of the urine detector.

[0041] In this embodiment, the housing assembly 1 includes an upper housing 11 and a lower housing 12 connected to each other. An inlet channel 121 and a detection channel 122 are disposed on the lower housing 12. A circuit board 21 is mounted on the side of the upper housing 11 facing the lower housing 12. The upper housing 11 and the lower housing 12 are made of biodegradable materials. Specifically, the upper housing 11 and the lower housing 12 can be made of biodegradable materials such as polylactic acid, polybutylene succinate, polycaprolactone, or polyhydroxyalkanoates, facilitating single-use and allowing direct flushing down the drain after use of the urine analyzer. The upper housing 11 and the lower housing 12 can be connected by snap-fit. The circuit board 21 has four pre-drilled circular holes for fixing to the connecting rod inside the upper housing 11. A chromatography guide plate can also be disposed on the lower housing 12, with the detection channel 122 disposed on the guide plate, and the color sensor 231 located directly above the dry reagent strip. Preferably, both the upper housing 11 and the lower housing 12 are hemispherical, with multiple liquid inlet channels 121 located in the central region of the side of the lower housing 12 facing the upper housing 11, and multiple detection channels 122 extending radially away from the central region in a direction away from the liquid inlet channels 121.

[0042] In this embodiment, there are eight detection channels 122, eight liquid inlet channels 121, and eight color sensors 231, all in a one-to-one correspondence. In other embodiments, there are two, four, or six detection channels 122, etc. Figure 4 As shown, when there are four detection channels 122, the four detection channels 122 are arranged in a cross shape on the side of the lower housing 12 facing the upper housing 11, and the four liquid inlet channels 121 are located in the central area of ​​the cross shape. The liquid inlet channels 121 extend vertically to the bottom of the urine analyzer.

[0043] Preferably, such as Figures 1-3As shown, the detection component 2 also includes an indicator component 25, which includes multiple warning lights 251. Each warning light 251 corresponds one-to-one with a multiple detection channel 122, and the warning lights 251 indicate the detection result of the liquid in the corresponding detection channel 122. In this embodiment, the warning lights 251 are electrically connected to the circuit board 21. When the concentration of the substance to be detected in the detection liquid is outside the standard concentration range, the warning light 251 illuminates red; when the concentration of the substance to be detected in the detection liquid is within the standard concentration range, the warning light 251 illuminates green; when the detection of the concentration of the substance to be detected in the detection liquid fails, the warning light 251 does not illuminate. This embodiment allows for visual inspection of the detection results, making it simple to operate and widely applicable. In this embodiment, there are eight warning lights 251, each used to indicate the detection result of the corresponding substance in one of the eight detection channels 122.

[0044] Furthermore, multiple warning lights 251 are installed on the side of the circuit board 21 opposite to the detection channel 122. The housing assembly 1 is provided with a light-transmitting hole 111, through which the light from the warning lights 251 can pass. In this embodiment, the hole is located on the top surface of the upper housing 11, and the light from the warning lights 251 is emitted through the light-transmitting hole 111, making it easy for the user to observe.

[0045] Furthermore, in this embodiment, the illumination component 22 includes multiple LED light sources 221, each corresponding to a multiple color sensor 231. The LED light sources 221 are disposed on the circuit board 21 and located to one side of the color sensor 231. This arrangement brings the LED light sources 221 closer to the dry reagent, increasing the brightness of the dry reagent and facilitating the color sensor 231 in collecting the reflected light from the dry reagent.

[0046] In other embodiments, the illumination component 22 includes an LED light source 221, which is located above the end of the plurality of detection channels 122 that communicates with the liquid inlet channel 121. The LED light source 221 can illuminate the dry reagents within the plurality of detection channels 122, reducing material costs.

[0047] In existing technologies, dry test strips are typically immersed directly in urine, and the color change is then observed. However, urine contains crystals, casts, and mucus, which can affect the color interpretation of the reagent. To address this issue, the urine analyzer also includes multiple chromatography elements, with each chromatography element, detection channel 122, and liquid inlet channel 121 corresponding to the others. The chromatography elements are attached to the detection channels 122 and the liquid inlet channels 121. A dry test strip is placed at one end of the chromatography element within the detection channel 122, while the other end within the liquid inlet channel 121 can absorb the test liquid. During use, the urine sample is guided through the liquid inlet channel 121 and the detection channel 122 containing the chromatography elements to the fixed dry test strip. The chromatography elements effectively trap crystals, casts, and mucus in the urine, preventing them from affecting the color interpretation of the dry test strip and improving detection accuracy. In this embodiment, the chromatography element is laid flat in the detection channel 122, and the dry reagent is adhered to the top of the chromatography element by adhesive.

[0048] Preferably, the chromatography element can be a chromatography column or chromatography paper. In this embodiment, the chromatography element is chromatography paper.

[0049] In this embodiment, a collection port 123 is provided at the inlet end of the liquid inlet channel 121, and the end of the chromatography element located inside the liquid inlet channel 121 blocks the collection port 123. In this embodiment, the color sensor 231 only requires a small amount of urine to meet the requirements of analysis and detection. By blocking the collection port 123 with the chromatography element, the detection liquid can only flow through the chromatography element, preventing excessive detection liquid from entering the urine detector and causing water damage to the circuit board 21. In this embodiment, the collection port 123 includes multiple small holes.

[0050] Furthermore, a counterweight 13 is provided at the bottom of the lower housing 12. The counterweight 13 is used to ensure that when the urine analyzer floats in the test liquid, the inlet end of the inlet channel 121 is located at the bottom.

[0051] This embodiment also provides the workflow of the urine analyzer, as follows:

[0052] Step 1: Collect urine into a urine cup;

[0053] Step 2: Press the switch on the urine analyzer to activate it, then place it in the urine cup. At this time, the collection port 123 will be directly below the urine analyzer.

[0054] Step 3: Urine is connected to the chromatography element through collection port 123;

[0055] Step 4: Draw the urine into the dry reagent section through the chromatography unit. At this time, the substance to be tested in the urine will react with the dry reagent to produce a color change. The entire test process takes less than 1 minute.

[0056] Step 5: After the microprocessor chip component 24 activates the urine detector for 1 minute, the LED light source 221 is turned on, and the color sensor 231 continuously receives the light signal reflected from the dry reagent within 5 seconds.

[0057] Step 6: The optical signal is converted into an electrical signal by the microprocessor chip component 24, and the data collected within 5 seconds is processed by the algorithm;

[0058] Step 7: The microprocessor chip component 24 calculates the reflectivity based on the electrical signal, calculates the concentration of the substance to be detected in the detection liquid based on the reflectivity, and finally indicates the positive or negative result by means of the warning light 251.

[0059] It should be noted that the microprocessor chip component 24 converts the optical signal into an electrical signal, calculates the reflectivity based on the electrical signal, and calculates the concentration of the substance to be detected in the liquid based on the reflectivity. This is existing technology, and the specific principle will not be elaborated here.

[0060] This urine analyzer is compact, portable, and disposable. It eliminates the need for integrated equipment design, addressing the pain points of existing routine urine tests which require a combination of urine analyzer, reagents, and mobile software / apps or laboratory information systems, or rely on visual methods with significant discrepancies. It also addresses the issues of complex operation, high cost, and maintenance requirements of existing products. This urine analyzer allows users to perform automatic urine tests while using the toilet, providing early warnings about their health status. The chromatography element ensures sufficient reaction between the sample and the dry reagent strip, filtering out the influence of formed elements in the urine on color recognition, thus ensuring the accuracy of the sample composition analysis results. The specific matching of the color sensor 231 and the dry reagent strip not only improves detection sensitivity but also significantly reduces material costs, providing the foundation for a disposable testing product. The rectangular detection channel 122 creates a dark chamber between itself and the color sensor 231, avoiding stray light interference and reducing the volume of the test liquid, requiring only a small sample to obtain results.

[0061] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
