However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0054] This utility model relates to a urine analyzer 100, which is small in size and highly efficient. It can also remove air bubbles from samples or water and is suitable for routine urine tests, such as 14 ascorbic acid tests, including vitamin C (VC), white blood cells (WBC), urobilinogen (URO), bilirubin (BIL), occult blood (BLD), nitrite (NIT), pH, protein (PRO), urine specific gravity (SG), urine ketones (KET), urine glucose (GLU), urine creatinine (CR), urine calcium (CA), and a comprehensive value of microalbumin (MA) + uric acid + UACR (urine microalbumin / creatinine ratio) + UPCR (urine protein / creatinine ratio) + uric acid (based on the CKD-EPI algorithm). The following is a detailed description of one embodiment of the urine analyzer 100 according to the accompanying drawings.

[0055] like Figures 1-5 As shown, the urine analyzer 100 includes a housing, a detection mechanism 3 located within the housing, a microfluidic chip, a sample driving module, a water driving module, a reagent driving module, multiple pipes, a battery 8, a sensor, a control module, and a support 6. The housing has a collection chamber 123 for collecting samples or water. The sample driving module includes a sample container 5, a pipe connecting the sample container 5 and the collection chamber 123, a pump connected to the pipe, and a pipe connecting the sample container 5 and the sample flow channel of the microfluidic chip, as well as a pump connected to the pipe.

[0056] like Figure 7 In the process, the water drive module includes a water container 4, a pipe connecting the water container 4 and the collection chamber 123, a pump connected to the pipe, a pipe connecting the water container 4 and the water flow channel of the microfluidic chip, and a pump connected to the pipe.

[0057] The reagent driving module includes multiple reagent capsules 7, reagent pipelines that connect the multiple reagent capsules 7 and multiple reagent channels of the microfluidic chip, and multiple reagent pumps connected to the multiple reagent pipelines.

[0058] like Figure 6 , Figure 7In this system, the water container 4 and sample container 5 are used to store water and samples, respectively. The reagent capsule 7 is used to hold the reagents for testing. The microfluidic chip is connected to the reagent capsule 7, sample container 5, and water container 4 to mix the reagents and samples. The detection mechanism 3 includes a test plate and a detection component. The test plate has a test chamber that is connected to the microfluidic chip and can accept the mixed liquid of the reagents and samples. The detection component detects the mixed liquid. The sensor is installed inside the housing and detects the liquid in the collection chamber 123. The control module can control the movement of multiple pumps or control the detection component 31 to detect based on the sensor signal. The battery 8 is used to power the multiple pumps or the detection component 31. The bracket 6 is located inside the housing and is used to fix the detection mechanism 3, battery 8, control module, reagent capsule 7, sample container 5, water container 4, and microfluidic chip.

[0059] Specifically, the housing is used to house the detection mechanism 3, the microfluidic chip, the sample driving module, the water driving module, the reagent driving module, the battery 8, the control module, and the bracket 6. The housing can also be installed on the inner wall of the toilet bowl, for example, it can be adhered to the inner wall of the toilet bowl.

[0060] In one embodiment, the housing includes a front shell 11 and a rear shell 12 connected to the front shell 11. The rear shell 12 is used to adhere to the inner wall of the toilet bowl, and the front shell 11 prevents foreign objects from entering the urine analyzer 100. Both the front shell 11 and the rear shell 12 have smooth arc surfaces protruding outwards. After the rear shell 12 adheres to the inner wall of the toilet bowl, the overall housing of the urine analyzer 100 is smooth and will not trap foreign objects. The entire front shell 11 and rear shell 12 can be connected by screws or snap-fit, etc., without limiting the specific connection method of the front shell 11 and rear shell 12.

[0061] The top of the rear shell 12 is provided with a recessed collection cavity 123, which is used to collect samples and water, namely urine.

[0062] exist Figures 1-9 In the specific embodiment shown, the rear shell 12 includes a connecting portion 121 and a cover 122. The connecting portion 121 is generally conical and annular with a smooth outer surface. That is, the diameter of the connecting portion 121 gradually decreases from the front end to the rear end. The front end is fixedly connected to the front shell 11 and matches the outer surface of the front shell 11, giving it a smooth arc surface appearance. The cover 122 is connected to the rear end of the connecting portion 121, and the rear end of the cover 122 is an arc surface protruding outward.

[0063] The collection chamber 123 is formed by a recess at the top of the cover 122 and has an opening at the top. The inner wall size of the collection chamber 123 is larger at the top to facilitate sample collection, while the bottom is smaller. The bottom of the collection chamber 123 is used for sample transport. Since some foam mixed in during sample collection will be eliminated as the sample flows to the bottom, it can be avoided from being transported to the test chamber and interfering with the test.

[0064] like Figure 5 and Figure 9 In the middle, the inner wall of the cover 122 is also recessed to form two grooves 124. The two grooves 124 are used to accommodate the water container 4 and the sample container 5. The two grooves 124 are distributed on both sides of the collection chamber 123. The two grooves 124 and the two sides of the collection chamber 123 share the same sidewall along the first direction, so that the grooves 124 are adjacent to the collection chamber 123, and the outer side of the grooves 124 is close to the radial outer side of the cover 122. That is to say, this arrangement of the two grooves 124 and the collection chamber 123 makes the most efficient use of the volume of the cover 122, which can reduce the volume of the entire urine analyzer 100.

[0065] The inner wall dimensions of the collection chamber 123 gradually decrease from top to bottom to facilitate sample collection. Figure 5 and Figure 6 In the illustrated embodiment, the collection cavity 123 has front and rear walls and two inner walls along a first direction. The rear wall is located on one side of the inner wall of the toilet bowl, and is an arc-shaped surface that protrudes slightly towards the rear end to facilitate receiving more samples. The front and rear walls are arranged opposite each other. The two inner walls of the collection cavity 123 along the first direction are arc-shaped surfaces that protrude towards each other; that is, the width of the collection cavity 123 along the first direction gradually decreases from top to bottom.

[0066] like Figure 5 , Figure 7 , Figure 8 , Figure 9 In the sampling chamber 123, five pipe holes 125 are provided on the two inner walls along the first direction. One pipe hole 125 is located at the top of one of the inner walls, near the top opening of the sampling chamber 123. This pipe hole 125 is used to communicate with the clean water container 4 to expel air bubbles from the clean water container 4. This pipe hole 125 is defined as the first vent hole 128. The other four pipe holes 125 are located at the bottom of the sampling chamber 123 and on both sides of the sampling chamber 123 along the first direction. Two of the four pipe holes 125 are used to communicate with the sample container 5 and the clean water container 4 through pipes. The other pipe hole 125 is connected to the test chamber through a drain pipe. The last pipe hole 125 is used to communicate with the sample container 5 to facilitate the expulsion of air bubbles. This pipe hole 125 is defined as the second vent hole 129, and the second vent hole 129 is located at the bottom of the sampling chamber 123. Of the five pipe holes 125 provided inside the collection cavity 123, four pipe holes 125 are close to the bottom of the collection cavity 123, and one pipe hole 125 is close to the top of the collection cavity 123.

[0067] like Figure 3As shown, the bottom of the collection chamber 123 is also provided with a drain port 126. The drain port 126 is very small, and during the process of receiving samples and clean water, the collection chamber 123 will not lose water quickly, but will only discharge it slowly, which will not affect the collection of samples. The operation of the pipe hole 125 and the drain port 126 will be described in detail below.

[0068] like Figure 3 As shown, the top opening of the collection chamber 123 is relatively large, and a filter section is also provided at the top opening. The filter section includes multiple rails 127 and a filter screen. The multiple rails 127 are arranged at intervals along the first direction and connected to the top of the collection chamber 123 to block larger foreign objects. The filter screen is located below the multiple rails 127 and connected to the inner wall of the collection chamber 123, covering the entire top opening of the collection chamber 123 for fine filtration.

[0069] A sensor is also installed inside the collection chamber 123. This sensor is connected to the control module and can sense whether the liquid collected in the collection chamber 123 is a sample or water, and transmit the collected signal to the control module.

[0070] The bracket 6 is installed inside the housing and supports the water container 4, sample driving module, reagent driving module, water driving module, microfluidic chip, and battery 8. The bracket 6 can be fixedly connected to the front housing 11 or the rear housing 12 by bolts, and the specific shape of the bracket 6 is not limited.

[0071] like Figure 10 As shown, the microfluidic chip includes a flow channel plate 2 and a capping plate connected to the flow channel plate 2. The flow channel plate 2 is a plate-shaped component extending along a first direction for mixing reagents and samples. Specifically, the front or rear surface of the flow channel plate 2 is provided with a recessed main flow channel 21, a sample flow channel 22, a water flow channel 24, an air flow channel 23, multiple reagent flow channels 28, and a mixing chamber 25. The main flow channel 21 extends along the first direction, which is perpendicular to the vertical direction.

[0072] The cover plate covers and connects to the front or rear surface of the flow channel plate 2, and covers the main flow channel 21, sample flow channel 22, water flow channel 24, air flow channel 23, multiple reagent flow channels 28, and mixing chamber 25. The cover plate and the main flow channel 21 work together to prevent liquid from overflowing from the main flow channel 21, sample flow channel 22, water flow channel 24, air flow channel 23, multiple reagent flow channels 28, and mixing chamber 25.

[0073] One end of the main channel 21 extends to the outer end of the microfluidic chip along the first direction, and the other end extends to approximately the middle part of the microfluidic chip.

[0074] One end of the sample channel 22, the water channel 24, the air channel 23, and the multiple reagent channels 28 are connected to the main channel 21, and the other end extends to the top or bottom of the microfluidic chip, for communication with the sample container 5, the water container 4, or the reagent capsule 7 via the channels. Figure 6 and Figure 10 In the illustrated embodiment, the sample channel 22, the water channel 24, the air channel 23, and the multiple reagent channels 28 are arranged at intervals on the top and bottom of the main channel 21, similar to tree branches. In other embodiments, other arrangements may also be used.

[0075] Specifically, such as Figure 12 In the sample container 5, the sample container 5 is connected to the sample flow channel 22 through a pipe, which is the first sample pipe 502. The sample container 5 is connected to the collection chamber 123 through another pipe, which is defined as the second sample pipe 503.

[0076] like Figure 12 In the sample container 5, the first sample conduit 502 is connected to one of the pumps, which is defined as the first sample pump 501. The first sample pump 501 is used to drive the sample in the sample container 5 into the sample flow channel 22 and into the main flow channel 21 through the sample flow channel 22.

[0077] like Figure 12 In the middle, the second sample pipeline 503 is connected to another pump, which is defined as the second sample pump 51. The second sample pump 51 is used to drive the sample in the collection chamber 123 into the sample container 5.

[0078] Similar to sample container 5, such as Figure 12 In the process, the clean water container 4 is also connected to the clean water channel 24 and the collection chamber 123 through two pipes respectively. The pipe connecting the clean water container 4 to the clean water channel 24 is the first clean water pipe 402, and the pipe connecting the clean water container 4 to the collection chamber 123 is the second clean water pipe 403.

[0079] The first clean water pipe 402 is connected to a pump, which is the first clean water pump 401. The first clean water pump is used to drive the water in the clean water container 4 from the first clean water pipe into the clean water flow channel 24, and then into the main flow channel 21.

[0080] The second clean water pipe 403 is connected to another pump, which is the second clean water pump 41. The second clean water pump 41 is used to drive the water in the collection chamber 123 to flow from the second clean water pipe into the clean water container 4.

[0081] In addition, such as Figure 4 and Figure 8As shown, the top of the water container 4 and the sample container 5 are respectively provided with vent holes. The vent hole of the water container 4 is connected to a pipe, which is the first exhaust pipe 42. The two ends of the first exhaust pipe 42 are respectively connected to the vent hole of the water container 4 and the first exhaust hole 128 of the collection chamber 123.

[0082] like Figure 4 and Figure 5 As shown, the vent of the sample container 5 is connected to another pipe, which is defined as the second exhaust pipe 52. The two ends of the second exhaust pipe 52 are connected to the vent of the sample container 5 and the second exhaust port 129 of the collection chamber 123, respectively.

[0083] like Figures 4-10 As shown, the flow rate of the second sample pump 51 is greater than that of the first sample pump 501, and the flow rate of the second water pump 41 is greater than that of the first water pump 401. In use, when the sensor detects sample collection in the collection chamber 123, the control module receives the sensor signal and drives the second sample pump 51 to operate. The second sample pump 51 has a larger flow rate, allowing it to extract a large amount of sample from the collection chamber 123 into the sample container 5. Because air bubbles are generated during rapid extraction, these bubbles and some sample enter the sample container 5 and can then exit through the air outlet at the top of the sample container 5, through the second exhaust pipe 52, and the second exhaust hole 129 at the bottom of the collection chamber 123, before being discharged from the bottom of the collection chamber 123. Meanwhile, the first sample pump 501 has a smaller flow rate, allowing it to quantitatively extract the sample from the sample container 5, which then enters the sample flow channel 22 through the sample pipe and flows into the main flow channel 21. This design effectively removes air bubbles from the sample, ensuring that no air bubbles are generated in the sample extracted by the first sample pump 501, thus avoiding interference with detection.

[0084] The same principle applies, such as Figures 4-10 As shown, when it is necessary to extract water from the collection chamber 123 to clean the microfluidic chip and the test chamber, a large amount of water from the collection chamber 123 needs to be extracted using the second clean water pump 41 and transferred to the clean water container 4. Then, the water in the clean water container 4 is pumped to the clean water flow channel 24 and the main flow channel 21 using the first clean water pump 401. Air bubbles in the clean water container 4 can enter the first vent hole 128 at the top of the collection chamber 123 through the vent hole and the first vent pipe 42. Since clean water has a washing effect, the air bubbles and water from the first vent hole 128 can flow into the collection chamber 123 after entering the top of the collection chamber 123, cleaning the collection chamber 123 again. Therefore, the first vent hole 128 is located at the top of the collection chamber 123. However, since air bubbles and samples from the sample container 5 can contaminate the collection chamber 123, the second vent hole 129 needs to be located at the bottom of the collection chamber 123 to avoid contamination.

[0085] When there are a lot of air bubbles in the clean water used for washing, it will also affect the cleaning effect. Therefore, after venting the air through the clean water container 4, the number of air bubbles entering the main channel 21 can also be reduced.

[0086] Of course, in other embodiments, if it is ensured that there are no air bubbles in the sample and water collected in the collection chamber 123, the clean water container 4 or the sample container 5 may not be provided. That is, the first clean water pipe 402 or the first sample pipe 502 is directly connected to the collection chamber 123, and water or samples are directly drawn from the collection chamber 123 to the main channel 21 by the corresponding pumps.

[0087] In addition, in order to maximize the filling of samples and water without taking up too much internal space, the sample container 5 and the water container 4 are designed to match the shape of the groove 124 as much as possible.

[0088] The first sample pump 501, the second sample pump 51, the first clean water pump 401 and the second clean water pump 41 are preferably peristaltic pumps. The second sample pump 51 has a small flow rate, which can achieve accurate quantitative extraction of samples to the main channel 21.

[0089] exist Figure 10 In the illustrated embodiment, the clear water channel 24 is located at the outer end of the main channel 21, meaning that both the clear water channel 24 and the main channel 21 extend along the first direction. The clear water channel 24 can also be considered as part of the outer end of the main channel 21. This ensures that the entire main channel 21 is thoroughly cleaned when the water is clear.

[0090] The reagent driving module is mounted on a bracket, wherein multiple reagent capsules 7 are fixed on the bracket 6 and are connected to multiple reagent channels 28 on the microfluidic chip through multiple reagent pipes. Each reagent pipe is connected to a reagent channel 28 and a reagent capsule 7 at both ends, and each reagent pipe is connected to a reagent pump 102.

[0091] like Figure 17 As shown, reagent pump 102 can draw reagent from reagent capsule 7 into reagent flow channel 28 and then into main flow channel 21. Depending on the testing requirements, reagent pump 102 can quantitatively draw reagent from reagent capsule 7 into main flow channel 21, resulting in more precise quantification. Peristaltic pump is also preferred for reagent pump 102.

[0092] Air duct 23 is connected to another pipe, which is defined as an air duct, and the air duct is also connected to a pump, which is defined as an air pump 101.

[0093] The air pump 101 can draw in external air from the air duct and then enter the main flow channel 21 through the air flow channel 23. Of course, it can also operate in reverse, drawing air from the main flow channel 21 out of the air duct to the outside. The air pump 101 is connected to the bracket 6 and is preferably a peristaltic pump.

[0094] The air channel 23 is close to the water channel 24, which is closer to the outer end of the sample channel. Air enters from the air channel 23, which can drive all the reagents or samples that have entered the main channel 21 to flow from the main channel 21 into the mixing chamber 25.

[0095] All of the pumps mentioned above are peristaltic pumps. In order to connect to the peristaltic pump, multiple pipes need to be divided into two sections, with each end connected to the two ends of the peristaltic pump's hose.

[0096] Specifically, the mixing chamber 25 is connected to one end of the main channel 21 located in the middle of the microfluidic chip. The mixing chamber 25 has a certain capacity and can be used to mix samples and reagents.

[0097] After the second sample pump 51 draws the sample into the sample container 5, the first sample pump 501 can draw the sample in the sample container 5 into the sample flow channel 22, and then flow from the sample flow channel 22 into the main flow channel 21. After that, the air pump 101 drives the air pipe to draw in external air into the main flow channel 21 and pushes the sample in the main flow channel 21 toward the mixing chamber 25 flow channel.

[0098] After the sample flows into the mixing chamber 25, the first sample pump 501 also needs to draw a portion of air from the main channel to the sample channel 22 in the reverse direction to prevent the reagent from flowing into the sample channel 22 during the flow of the main channel 21.

[0099] The reagents also flow into the mixing chamber 25 in the same way. Specifically, after the reagent pump 102 draws the reagent in the reagent capsule 7 into the main channel 21 through the reagent pipeline, the air pump 101 draws in external air into the main channel 21, pushing the reagent in the main channel 21 into the mixing chamber 25. Then, the reagent pump needs to operate in reverse, drawing a portion of the air in the main channel 21 into the reagent flow channel 28.

[0100] The mixing chamber 25 is connected to the test chamber. After the reagent and sample enter the mixing chamber 25, the air pump 101 can draw air into the mixing chamber 25 to drive the reagent and sample to tumble and mix in the mixing chamber 25 to obtain a mixed liquid. The air pump 101 can drive the mixed liquid in the mixing chamber 25 to the test chamber.

[0101] In a preferred embodiment, the microfluidic chip also includes a mixing bend 26, the two ends of which are connected to the test chamber and the mixing chamber 25, respectively. The mixing bend 26 is a curved pipe.

[0102] After the reagents and samples enter the mixing chamber 25, the air pump can drive the reagents and samples in the mixing chamber 25 from the mixing chamber 25 into the mixing bend 26, and then return from the mixing bend 26 to the mixing chamber 25. After going back and forth two or three times, the reagents and samples are fully mixed, and then the mixed liquid is driven from the mixing chamber 25 and the mixing bend 26 into the test chamber.

[0103] The sample or reagent needs to be propelled towards the mixing chamber 25 by gas to mix, and the gas also needs to separate the sample and reagent as they enter the mixing chamber 25. Therefore, bubbles will be generated during the flow of the sample or reagent. However, after the sample and reagent are mixed multiple times in the mixing chamber 25, the bubbles will be broken and will not flow into the test chamber to interfere with the detection.

[0104] exist Figure 10 In the illustrated embodiment, the mixing chamber 25 and the main channel 21 extend along a first direction, which is perpendicular to the vertical direction. The mixing chamber 25 includes a first segment 251, a mixing chamber 252, and a tail segment 253 that are connected to each other. The first segment 251 extends along the vertical direction, with its bottom end connected to the main channel 21 and its top end connected to the mixing chamber 252. The tail segment extends along the first direction and is slightly lower than the main channel 21. Both ends of the tail segment 253 are connected to the mixing chamber 252 and the mixing bend 26, respectively.

[0105] The mixing chamber 252 is roughly baseball-shaped, with its top end connected to the first segment 251 and its bottom end connected to the tail segment. Of the two side walls of the mixing chamber 252 arranged opposite each other along a first direction, one side wall includes a first arc surface 254, and the other side wall includes a second arc surface 255 and a third arc surface 256 connected to each other.

[0106] The first arc surface 254 is an arc surface formed by a concave curve away from the second arc surface 255. One end of this arc surface is tangent to a horizontal plane, and the other end is tangent to a vertical plane. Preferably, the radius of the first arc surface 254 ranges from 5mm to 8mm, and the arc length ranges from 7mm to 10mm. More preferably, the radius of the first arc surface 254 is 5mm, and the arc length is 7.85mm. The first arc surface 254 is not directly connected to the first segment 251 or the tail segment. The top end of the first arc surface 254 needs to be connected to the first segment 251 through a horizontal inner wall, while the bottom end is connected to a vertical inner wall that extends to the tail segment.

[0107] The second arc surface 255 is an arc surface that is concave away from the first arc surface 254. That is, both the second arc surface 255 and the first arc surface 254 are concave arc surfaces facing outward. The bottom end of the second arc surface 255 is tangent to a horizontal plane, while the top end is tangent to a vertical plane. The bottom end of the second arc surface 255 is connected to the tail section through a horizontal inner wall.

[0108] As a preferred embodiment, the radius of the second arc surface 255 ranges from 5mm to 8mm, and the arc length ranges from 7mm to 10mm. More specifically, the radius of the second arc surface 255 is 5mm, and the arc length is 7.85mm.

[0109] The third arc surface 256 is an arc surface that curves toward the interior of the mixing cavity 25. The third arc surface 256 is located at the top of the second arc surface 255, and the bottom end of the third arc surface 256 is tangent to a vertical plane, which overlaps with the vertical plane that is tangent to the top end of the second arc surface 255. The top end of the third arc surface 256 is tangent to a horizontal plane, which is located below the horizontal plane that is tangent to the top end of the first arc surface 254.

[0110] As a preferred embodiment, the radius of the third arc surface 256 ranges from 0.75mm to 2mm, and the arc length ranges from 1.5mm to 3mm. More specifically, the radius of the third arc surface 256 is 2mm, and the arc length is 3mm.

[0111] The bottom end of the third arc surface 256 can be directly connected to the top end of the second arc surface 255, or they can be separated by a vertical inner wall. The height of the mixing chamber 25 in the vertical direction ranges from 8mm to 12mm, and the width in the first direction is 7mm to 9mm. As a preferred embodiment, such as... Figure 11 The height h1 of the mixing chamber 252 in the vertical direction is 9.75 mm, and the width w1 in the first direction is 8 mm.

[0112] The diameter of the mixing bend 26 is in the range of 1mm-2mm, more preferably 1.5mm.

[0113] Experiments have shown that the best mixing effect is achieved when the sample and reagent flow back and forth once in the mixing chamber 25 and the mixing bend 26. In other words, the best mixing effect is achieved when the sample and reagent flow from the mixing chamber 25 into the mixing bend 26 and then return to the mixing chamber 25.

[0114] The required volume of the mixed liquid for testing is approximately 55 μm. Multiple experiments have shown that the above-mentioned dimensions of the mixing chamber 25 and the mixing bend 26 not only ensure that the mixed liquid does not return to the main channel 21 during the mixing process, but also ensure that it is fully mixed.

[0115] In another embodiment, such as Figures 13-15 As shown, the flow channel plate is provided with another mixing chamber, defined as the second mixing chamber 257. The second mixing chamber 257 also extends along the first direction, with one end connected to the main flow channel 21 and the other end connected to the test chamber. Furthermore, the top wall of the second mixing chamber 257 gradually increases in height from both ends to the middle along the first direction, and the top wall of the second mixing chamber 257 is an arc surface. Of course, in this embodiment, the microfluidic chip is also provided with a water flow channel, a reagent flow channel, and an air flow channel connected to the main flow channel, operating in the same way as in the previous embodiment. Figure 12 and Figure 14 These flow channels were not displayed.

[0116] Of course, a mixing bend (not shown in the figure) can also be provided at the rear end of the second mixing chamber 257. The two ends of the mixing bend are connected to the second mixing chamber 257 and the test chamber, respectively. Similar to the previous embodiment, after the reagent and sample flow into the second mixing chamber 257, the air pump drives the reagent and sample to flow from the second mixing chamber 257 into the mixing bend, and repeatedly backflows to mix the reagent and sample. Then the mixed liquid is driven into the test chamber.

[0117] Preferably, such as Figure 14 As shown, the width w2 of the second mixing chamber 257 along the first direction is 20mm-24mm. The height h2 of the second mixing chamber 257 along the vertical direction is 3mm-4mm.

[0118] Preferably, such as Figure 14 In the process, the radius r of the main channel is 0.5mm-1mm. The inner wall of the second mixing chamber 257 includes a first section 2571 protruding outward and a second section 2572 recessed inward. The first section 2571 and the second section 2572 are preferably arc surfaces. The bottom end of the first section is connected to the inner wall of the main channel, and the top section and the bottom end of the second section are connected.

[0119] Both the first and second segments are preferably arc surfaces, with the radius of the first segment's arc surface preferably ranging from 3mm to 5mm. The depth of the second segment's inward concavity is greater than the depth of the first segment's inward concavity, with the depth d of the second segment's inward concavity ranging from 1.0mm to 2.2mm.

[0120] The size of the mixing chamber determines its mixing effect and the backflow of liquid. Therefore, the mixing chamber size and main channel size obtained by this invention through multiple experiments can ensure the mixing effect.

[0121] like Figure 15 During the process, the liquid in the second mixing chamber 257 does not rise to the top wall of the second mixing chamber 257, meaning the liquid does not come into contact with the second section 2572 of the second mixing chamber 257. The liquid exhibits an angular flow effect, meaning it adheres to the inner wall of the second mixing chamber 257 during flow. When the liquid flows into the second mixing chamber 257 from the main channel 21, an outward-curving arc surface forms on the liquid surface at the end of the second mixing chamber 257 closest to the main channel 21. Conversely, when the liquid flows out of the second mixing chamber 257 to the mixing bend or the test chamber, i.e., when the liquid flows from the second mixing chamber 257 to the outside, an outward-concave arc surface also forms on the liquid surface at the end of the second mixing chamber 257 furthest from the main channel 21. The two arc surfaces formed during the entry and exit of the liquid from the second mixing chamber 257 enclose a roughly spherical space capable of accommodating air bubbles. The air bubbles are broken within this space, thus reducing the amount of air bubbles flowing from the second mixing chamber 257 into the test chamber.

[0122] After the sample and reagents are mixed, the mixed liquid enters the test chamber from the second mixing chamber 257 and the mixing bend. Figure 4 In the illustrated embodiment, a pipe is connected between the test chamber and the mixing bend. In other embodiments, the test chamber can be set directly on the microfluidic chip, or the test board can be set adjacent to the microfluidic chip. The test chamber can also be directly connected to the mixing bend.

[0123] The test chamber is a cavity extending along the first direction, and the width of the test chamber in the vertical direction gradually increases from both ends to the middle. The top wall of the test chamber gradually rises from both ends to the middle, while the bottom wall of the test chamber gradually decreases from both ends to the middle. The bottom wall of the test chamber forms a pit to facilitate the holding of mixed liquids for testing.

[0124] The detection component 31 includes a light source and a photosensitive sensor, which are respectively disposed at corresponding positions on the test plate. The test plate is made of transparent material, the light source is an LED light used to illuminate the mixed liquid in the test chamber, and the photosensitive sensor is used to sense the light emitted by the light source after illuminating the mixed liquid, in order to detect the sample composition.

[0125] After sufficient sample is collected in the collection chamber 123, any excess sample will be discharged from the drain port 126 at the bottom of the collection chamber 123. When the operator flushes the toilet bowl, water will be collected in the collection chamber 123. After the sensor detects the collected water, it will transmit the information to the control module. The control module will control the second clean water pump 41 to draw a large amount of water from the collection chamber 123 into the clean water container 4. After the test is completed, the detection component 31 will send the detection information to the control module. The control module will control the first clean water pump 401 to pump the water in the clean water container 4 into the clean water flow channel 24 and the main flow channel 21, while the air pump will drive the water in the main flow channel 21 to the mixing chamber 25, the mixing bend 26 and then into the test chamber, and finally discharge it from the test chamber.

[0126] Of course, the test chamber can be connected to one of the pipe holes 125 at the bottom of the collection chamber 123 via a drain pipe. An air pump can pump the mixed liquid detected in the test chamber from the test chamber into the drain pipe, and then from the drain pipe to the collection chamber 123, and discharged into the toilet through the drain port 126 at the bottom of the collection chamber 123.

[0127] In another embodiment, the test plate is disposed adjacent to the rear shell 12, and the test chamber can also be provided with a drain port 126. The drain port 126 can extend directly to the outside of the rear shell 12. After the test is completed, the mixed liquid in the test chamber can also be discharged directly from the drain port 126.

[0128] As a preferred option, such as Figure 10As shown, the microfluidic chip also includes a washing channel 27. One end of the washing channel 27 is connected to the main channel 21, and the other end is connected to a container holding detergent via a washing pipe, which is defined as the washing container. The washing pipe is also connected to a washing pump 103.

[0129] After the test is completed, before the control module drives the second clean water pump 41 to draw water from the clean water container 4, it first controls the washing pump 103 to draw the washing liquid in the washing container to the main channel 21, and then controls the second clean water pump 41 to draw water from the clean water container 4 into the main channel 21. The air pump drives the water and washing liquid in the main channel 21 into the mixing chamber 25. The water and washing liquid flow repeatedly in the mixing chamber 25 and the mixing bend 26 to mix the water and washing liquid. After the water and washing liquid are mixed, the air pump is then controlled to push the mixed washing liquid from the mixing chamber and the mixing bend into the test chamber in sequence, and then discharged from the test chamber.

[0130] Optionally, the washing pump 103 drives the detergent in the container to enter the main channel 21 from the washing channel 27 to obtain a mixed washing liquid. The air pump continues to push the mixed washing liquid through the mixing chamber 25 and the mixing bend 26 to the test chamber, and then from the test chamber and the drain pipe to the collection chamber 123. Finally, it is discharged from the drain port 126 of the collection chamber 123 into the toilet bowl.

[0131] This utility model also relates to a control method for the urine analyzer 100. In one embodiment, the urine analyzer 100 includes a housing, a detection mechanism 3, a sensor, a microfluidic chip, a first sample pump 501, a reagent pump, an air pump, and a control module. The top of the housing has a collection chamber 123. The sensor is used to sense the sample and water within the collection chamber 123; this sensor can be an infrared sensor or other sensors. The microfluidic chip has a main flow channel 21, a mixing chamber 25, a sample flow channel 22, an air flow channel 23, and multiple reagent flow channels 28. The first sample pump 501 is connected to a first sample conduit 502. The multiple reagent pumps are connected to multiple reagent conduits. The air pump is connected to an air conduit.

[0132] like Figure 16 As shown, the control method includes the following steps:

[0133] S1. After the sensor senses the information of the sample collected in the collection chamber 123, it transmits the information to the control module. The control module controls the first sample pump 501 to enter the main flow channel 21 from the sample flow channel 22 according to the information of the sensor. Then, it controls the air pump to push the sample in the main flow channel 21 into the mixing chamber 25. Then, it controls the first sample pump 501 to draw a part of the air from the main flow channel 21 into the sample flow channel 22.

[0134] S2. The sensor detects water collected in the collection chamber 123 and transmits the information to the control module. The control module controls the reagent pump to drive the reagent in the reagent capsule 7 from the reagent flow channel 28 into the main flow channel 21. Then, it controls the air pump to push air into the main flow channel 21, thereby pushing the reagent in the main flow channel 21 into the mixing chamber 25. Then, it controls the reagent pump to draw a portion of the air from the main flow channel 21 into the reagent flow channel 28.

[0135] S3. The control module controls the air pump to repeatedly push the sample and reagent in the mixing chamber 25 to flow in the mixing chamber 25. After obtaining the mixed liquid, the air pump is then controlled to push the mixed liquid from the mixing chamber 25 to the test chamber.

[0136] S4. The control module controls the detection component 31 to detect the mixed liquid in the test chamber.

[0137] In a preferred embodiment, a sample container 5, a second sample pipeline 503, and a second sample pump 51 are disposed inside the housing. The sample container 5, the second sample pump 51, and the second sample pipeline 503 have been described above and will not be described in detail again.

[0138] In this case, in step S1, the control module first controls the second sample pump 51 to drive the sample in the collection chamber 123 into the sample container 5, and then controls the first sample pump to drive the sample in the sample container 5 from the sample flow channel 22 into the main flow channel 21.

[0139] In another preferred embodiment, the microfluidic chip includes a curved mixing channel 26, and the two ends of the mixing cavity 25 are respectively connected to the main channel 21 and the mixing channel 26, and the two ends of the mixing channel 26 are respectively connected to the mixing cavity 25 and the test cavity.

[0140] In step S3, after the sample and reagent enter the mixing chamber 25 from the main channel 21, the control module controls the air pump to repeatedly push the sample and reagent in the mixing chamber 25 from the mixing chamber 25 into the mixing channel and then back to the mixing chamber 25 to obtain a mixed liquid. Then, the air pump is controlled to push the mixed liquid sequentially through the mixing chamber 25 and the mixing bend 26 to the test chamber.

[0141] Preferably, the microfluidic chip is further provided with a clean water channel 24, one end of which is connected to the main channel 21, and the other end is connected to the collection chamber 123 through a first clean water pipe, which is connected to a first clean water pump 401.

[0142] After the test is completed, that is, after step S4, there is step S5. After the detection component 31 detects the mixed liquid in the test chamber, it transmits the detection information to the control module. The control module controls the first clean water pump 401 to drive the water in the collection chamber 123 into the main channel 21. The control module controls the air pump to draw air into the main channel 21 and drive the water in the main channel 21 from the main channel 21 through the mixing chamber 25 and the mixing bend 26 to the test chamber, and finally discharges from the test chamber.

[0143] Furthermore, the housing may also include a clean water container 4, a second clean water pipe 403, and a second clean water pump 41. The two ends of the second clean water pipe 403 are connected to the collection chamber 123 and the clean water container 4, respectively. The two ends of the first clean water pipe 402 are connected to the clean water container 4 and the clean water flow channel 24, respectively. The second clean water pump 41 is connected to the second clean water pipe 403.

[0144] In step S5, after the detection component 31 detects the mixed liquid in the test chamber, the control module first controls the second clean water pump 41 to drive the water in the collection chamber 123 to flow into the clean water container 4, and then controls the first clean water pump 401 to drive the water in the clean water container 4 to enter the main flow channel 21 from the clean water flow channel 24. The air pump drives the water in the main flow channel 21 to pass through the mixing chamber 25, the mixing bend 26 and the test chamber in sequence, and finally discharges from the test chamber.

[0145] Furthermore, the microfluidic chip is also provided with a washing channel 27, which is connected to the main channel 21 and connected to a container holding detergent through a washing pipe.

[0146] The urine analyzer 100 also includes a washing pump, which is connected to the washing pipe;

[0147] In step S5, after the detection component 31 detects the mixed liquid in the test chamber, the control module controls the washing pump to drive the detergent in the container to enter the main channel 21 from the washing channel 27. The second clean water pump 41 drives the water in the collection chamber 123 to flow into the clean water container 4. After the first clean water pump 401 drives the water in the clean water container 4 to enter the main channel 21 from the clean water channel 24, the air pump draws air into the main channel 21 and drives the water and detergent in the main channel 21 to flow from the main channel 21 into the mixing chamber 25, the mixing bend 26 and then into the test chamber, and finally out of the test chamber.

[0148] Further, in step S5, the control module controls the air pump to draw air into the main channel 21, and drives the water and detergent in the main channel 21 to flow into the mixing chamber 25. Then, the control module controls the air pump to repeatedly push the water and detergent in the mixing chamber 25 from the mixing chamber 25 into the mixing bend 26 and then back to the mixing chamber 25 to obtain a mixed washing liquid. Then, the control module controls the air pump to push the mixed washing liquid through the mixing chamber 25 and the mixing bend 26 to the test chamber in sequence, and finally discharge it from the test chamber.

[0149] Furthermore, the test chamber is connected to the collection chamber 123 via a sewage pipe, and the bottom of the collection chamber 123 is provided with a sewage outlet 126.

[0150] In step S5, the control module controls the air pump to draw air into the main channel 21, and drives the water and reagent in the main channel 21 to pass through the mixing chamber 25 and the mixing bend 26 in sequence to the test chamber, and then flow into the collection chamber 123 through the sewage pipe and are discharged from the sewage outlet 126.

[0151] All of the pumps mentioned above are preferably peristaltic pumps, especially pumps that drive reagents, as peristaltic pumps can improve accuracy.

[0152] The control module is mounted on the circuit board 9, which is fixed to the bracket 6. The control module and the detection mechanism 3 are fixed to the middle part of the bracket 6, located at the rear end of the microfluidic chip.

[0153] After the urine analyzer 100 performs the test, it sends the spectral data to the computing device, which then analyzes the spectral data of the current user's urine to obtain the current user's urine test data.

[0154] As a preferred embodiment, the housing also includes a wireless communication module (WIFI, 4G, 5G, etc.), through which the control module transmits spectral data or urine test data to the cloud server. Once the computing device has collected enough sample information from the current user to be tested to meet the requirements of the configured user state prediction model, it automatically inputs the sample information from the current user within a first set time period into the user state prediction model. The user state prediction model then outputs the user's physiological indicator data for a second set time period under the current environmental conditions, thus forming a continuous time period (first set time period + second set time period) of user physiological indicator data. Alternatively, the user can trigger the user state prediction model through a user terminal (mobile phone, tablet, or other electronic device). Specifically, the user sends a prediction request to the computing device through their terminal. Upon receiving the prediction request, the computing device determines the user's sample information for the first set time period required for prediction based on the user's identity information and inputs it into the user state prediction model to obtain the user's physiological indicator data for the second set time period.

[0155] After predicting the health type of the user being tested using the health classification model, the prediction results of the user status within the region can be analyzed, and a comprehensive assessment can be made by combining information from various aspects such as the user's physiological indicators, lifestyle habits, and environmental factors. Based on the prediction results of the user's health classification and physiological indicators, the overall health status of the user can be determined, and it can be determined whether the user has any potential health problems.

[0156] The collection cavity 123 of this invention is designed with a larger opening at the top and a smaller opening at the bottom. The sample flows into the sample container 5 from the bottom of the collection cavity 123. During the process of the sample flowing from the top to the bottom, some air bubbles can be reduced.

[0157] Furthermore, a sample container 5 is used during the collection process. The sample container 5 is equipped with an air vent. The sample in the collection chamber 123 is drawn into the sample container 5 by the second sample pump 51, and the sample container 5 is drawn into the microfluidic chip by the first sample pump. This can reduce the amount of air bubbles transported into the microfluidic chip during the collection process and improve the detection accuracy.

[0158] In addition, the microfluidic chip is equipped with a mixing chamber 25 and a mixing bend 26. The shape of the mixing chamber 25 has been improved, which not only facilitates the mixing of reagents and samples, but also ensures that the reagents and samples are mixed by using an air pump to drive the reagents and samples to flow repeatedly in the mixing chamber 25 and the mixing bend 26, thereby reducing the flow of air bubbles into the test chamber and improving the detection accuracy.

[0159] The urine analyzer 100 of this invention uses multiple pumps to drive multiple reagents, samples, water and air respectively, which can improve the driving efficiency. Moreover, by using the mixing chamber 25 and the mixing bend 26, the mixing effect of reagents and samples, as well as water and reagents, can be improved.

[0160] This utility model also relates to a toilet, which includes a toilet body and the aforementioned urine analyzer. The urine analyzer is attached to the inner wall of the toilet body and is located near the front end. The rear shell 12 of the housing is adhered to the inner wall of the toilet body, and the top opening of the collection chamber 123 is used to collect samples and water.
