[0019] The beneficial effects of the present invention are:
[0020] (1) The urine testing storage system provided by the present invention can maximize space saving and synchronized operation of the device through the special arrangement of the reel structure of the untested test paper storage space and the tested test paper storage space, thereby realizing the simultaneous storage of untested test paper, urine sampling, and urine testing in the same device. The operation is simple, convenient, and fast.
[0021] (2) The present invention can be expanded into an automatic urine collection and detection device. Through the pump sampling system, sampling can be completed in a timely and quantitative manner to prevent waste of test paper. In addition, through timely and quantitative sampling, the device can achieve stable output of detection results, thereby ensuring the stability of the detection results.
[0022] The untested test paper space and the tested test paper space are set to rotate synchronously, which can realize the automatic collection and detection of urine. The sampling and detection are fully automatic during use, which is convenient and fast.
[0023] (3) The present invention can be expanded into an automatic urine collection and detection device, which uses a micro piezoelectric ceramic pump chip for urine sampling. The piezoelectric micropump is a component that uses the mechanical vibration of the piezoelectric vibrator after applying voltage to change the volume of the pump chamber to generate a pressure difference between the inside and outside of the pump chamber, thereby achieving continuous fluid delivery. Its structure is simple. This technical solution can analyze the hydraulic pressure, contraction / expansion tube resistance and other characteristics of the micropump microchannel based on the flow rate and pressure requirements of urine sampling; obtain the maximum speed and maximum pressure of the microchannel, and then achieve more stable sampling, minimize the error in the detection results caused by sampling, and improve the stability of the equipment.
[0024] (4) The present invention can be expanded into an automatic urine collection and detection device, which can place the test paper into the turntable through a mechanical structure system, so that the test paper can complete the sampling, detection and recovery in one step during the "tape-like" rotation process in the device. It is not only simple to use, but also very fast and convenient in detection. The provision of a support column and a sleeve can make the test paper run more stably in the device to complete the liquid collection and detection steps.
[0025] (5) The present invention can be expanded into an automatic urine collection and detection device, which is also provided with a flushing hole, and a test paper flushing window is left on the right side of the tested test paper, which can be used to flush the discarded test paper to reduce residual urine and reduce the odor that may be generated during the storage of discarded test paper; a semi-enclosed chamber is used inside to separate the test paper, and the outer wall of the chamber is used as a guide groove for residual waste liquid, so that the residual liquid in the dripping and flushing process can flow out through the opening (drain hole) below to prevent contamination of unused clean test paper; a handle is designed on the front for taking, which is convenient for replacing the test paper after use.
[0026] (6) The present invention can be expanded into an automatic urine collection and detection device, and adopts a special test paper, which is provided with a section to be tested, a detection identification point and a middle hollow structure. The detection identification point is provided in the section to be tested to ensure that the detection can identify the start and end positions of the detection. The hollow structure can prevent the micro-fluidic pump cleaning step and other waste liquids after the test from affecting the section to be tested, thereby causing it to produce detection errors.
[0027] (7) The present invention can be expanded into an automatic urine collection and detection device, which uses LED white light source for illumination to achieve urine test strip color sensing, thus ensuring that each sensing is performed under specific lighting conditions. At the same time, the wedge-shaped incident hole structure is adopted. On the one hand, the sampling is clearer, and on the other hand, the sampling can be carried out under the condition of fixed field of view width, which saves more test strips. At the same time, since the field of view of each sampling is fixed, the detection results are also more stable.
[0028] (8) The present invention can be expanded into an automatic urine collection and detection device, which performs data screening in specific steps on the color collection results, can effectively eliminate difference data, better increase data accuracy, and achieve stable detection results.
[0029] (9) The present invention can be expanded into an automatic urine collection and detection device, providing a precise hardware module control structure. Taking the microfluidic pump as an example, the control of the microfluidic pump is completed through a precise closed-loop control system. The system includes a microfluidic pump and a microfluidic pump controller. The microfluidic pump controller can realize the fusion of the characteristics of the microfluidic pump and urine detection through a boost circuit, thereby achieving accurate sampling and sufficient sampling. The present invention can also further add some modules to achieve more precise or detailed control, such as adding a flow sensor, etc. In general, the present invention can achieve accurate urine sampling and ensure the stability of the test results. At the same time, through the developed closed-loop control system, the microfluidic pump can also automatically adjust the sampling characteristics under different working conditions to achieve the purpose of precise control of sampling.
[0030] Similarly, in order to achieve the effective effect of this device, this device can also be expanded into a urine detection control system based on a user terminal, a cloud server and a urine detection device. The user directly starts the device by scanning the QR code of the device. After the device takes a sample, the test result is sent to the cloud server. The cloud server uses its algorithm to analyze the result and sends it to the user terminal and stores it in the corresponding database at the same time. It is one-click operation, convenient and fast, and relevant data can be queried at any time.
[0031] (10) This device or system is not limited to use in routine urine testing items, but can also be used in other urine testing items, such as drug testing, pregnancy testing, or heavy metal testing. Through the structure of this device, it only needs to replace the test paper with different functions to achieve the universal application of multiple urine testing items. Therefore, this device has a wide range of applications and good application prospects.
[0032] Overall, this device and system are easy to use, allowing all urine test procedures to be completed with a single click while maintaining a clean and hygienic environment. Through microfluidic technology, a series of operations, including sampling, testing, recovery, and cleaning, can be integrated into a small urine testing device, which can be easily integrated with a smart toilet. On this basis, combined with the concept of big data health, through software development, the long-term accumulation of routine urine test data for each user, and then cooperation with professional medical institutions to integrate and analyze this data, can achieve overall health status monitoring, disease prevention, and health trend analysis for each user and even a region.

[0045] The present invention will be further described below with reference to the accompanying drawings and examples:
[0046] Example 1
[0047] like Figure 1 As shown, the present invention provides embodiment 1, an automatic urine collection and detection device, including a housing and a sampling system B. The inner cavity of the housing is provided with a test paper conveying system C and a color recognition system D. The urine detection device in this embodiment is a color recognition system. Other recognition systems can also be used for urine detection in other embodiments.
[0048] The test paper conveying system includes an untested paper storage space C1 and a tested paper storage space C2. The test paper to be tested extends from the untested paper storage space C1 to the tested paper storage space C2. A reel C3 is provided in the middle of the tested paper storage space. Figure 3 The reel is connected to an external power mechanism C5 for reeling in the tested paper.
[0049] The sample drop device B1 and the color recognition system D in the sampling system are sequentially arranged on the extension path of the test paper from the untested paper storage space to the tested paper storage space.
[0050] The shell in this embodiment is a sealed shell, which is not marked in the legend of this embodiment and is not limited to referring to a specific shell. In this embodiment, a sealed solid shell is provided outside the fixing part and the test paper storage box. In other embodiments, it can also be directly integrated into other household devices, such as the inside of a toilet, so that the toilet and other devices themselves form a sealed environment. The toilet or other devices here are also covered by the shell here.
[0051] Such as Figure 1 As shown, the sampling system B of the collection and detection device is a pump sampling system, which includes a liquid inlet B2, the other end of the liquid inlet B2 is connected to a pumping device B3 through a liquid inlet pipe, the other end of the pumping device B3 is connected to a liquid outlet (not marked in the figure) through a liquid outlet pipe, and the liquid outlet is connected to a sample dropping device B1, which is fixedly arranged in the inner cavity of the shell and separated from the test paper storage space.
[0052] like Figure 4In this embodiment, for the sake of convenience, the pumping device is set on the surface of the shell or the fixing part. In other embodiments, the pumping device can also be placed outside the shell, such as in an integrally molded smart toilet, it can be set inside the toilet.
[0053] The pumping device is connected to a pumping drive device, and the pumping drive device is electrically connected to a pumping controller. The pumping controller is used to adjust the pumping speed and the unit pumping flow rate.
[0054] Since urine sampling is a very precise process, in order to achieve clear color display and sufficient data collection, in this embodiment, we can draw about 2ml into the solution chamber of the pump at a frequency of 2HZ, and then drip the sample at a rate of about 0.04ml. Quantitative and fixed-frequency pumping helps to achieve accurate judgment of urine sampling. At the same time, in this embodiment, a pumping drive device and a pumping control device are provided to achieve on-demand adjustment of the pumping speed and unit pumping flow rate. Of course, in other embodiments, the pumping frequency and the amount of liquid dripping can be adjusted according to actual conditions, and the pumping drive device and the pumping control device can be integrated.
[0055] The pumping device is arranged in the inner cavity of the shell; and the pumping controller is integrated on the microprocessor of the urine device.
[0056] Example 2
[0057] The pumping device in this embodiment is configured as a microfluidic pump. More specifically, the microfluidic pump is configured as a piezoelectric micropump, which uses a piezoelectric vibrator with a frequency of 2 Hz.
[0058] The pumping device in this embodiment is configured as a piezoelectric micropump. This piezoelectric micropump applies voltage to a piezoelectric ceramic disc, causing the pump's liquid-holding chamber to contract or expand. Both the inlet and outlet pipes connected to the piezoelectric micropump are equipped with one-way valves. The piezoelectric micropump's driver or controller controls the inflow and outflow of liquid. Piezoelectric micropumps are particularly well-suited for small-volume sampling devices, particularly urine sampling. In this embodiment, a 2Hz piezoelectric vibrator is used to pump urine. In other embodiments, piezoelectric vibrators with frequencies between 0.5Hz and 10Hz can also be used to achieve the same function.
[0059] The piezoelectric micropump driving device here includes a signal amplification circuit. In the present embodiment, the signal amplification circuit here is a boost circuit. This is because when sampling, if the voltage is too small, the sampling flow of the piezoelectric micropump cannot meet the requirements. Therefore, the piezoelectric micropump sampling device needs to complete boosting while ensuring that the signal remains unchanged; the driving voltage of the piezoelectric vibrator is about 100V, thereby enabling sufficient sampling of urine. The control drive unit is used to adjust the driving signal output to a suitable microfluidic pump according to the output signal to control the output state of the microfluidic pump. Through the developed closed-loop control system, the purpose of accurate control of sampling is achieved. In other embodiments, different driving voltage amplification operations can also be performed according to the characteristics of different urines.
[0060] A very important point in using this automatic sampling device is that a cleaning pipe is provided on the liquid inlet, and a control valve is provided on the cleaning pipe to achieve cleaning after sampling.
[0061] A key issue in sampling with a pumping device is how to clean the sampling device. In this embodiment, the sampling device can be cleaned by installing a cleaning pipe on the liquid inlet pipe or the liquid inlet. In other embodiments, cleaning can also be achieved by other means.
[0062] like Figure 3 Specifically, both the untested paper storage space C1 and the tested paper storage space C2 are configured as roller structures; a test paper sealing sleeve C11 is provided on the untested paper storage space, and a test paper outlet C12 is provided on the test paper sealing sleeve C11. A first test paper support column C13 is provided on one side of the test paper outlet C12, and a rolling device C131 is provided on the first test paper support column. In this embodiment, the first support column is used to provide support for the test paper during its extension path, and the rolling device is used to reduce friction when the test paper passes through, preventing the test paper outlet on the sealing sleeve from rubbing against the test paper and causing damage. The rolling device can be configured as a sleeve, a steel ball bearing structure, or other structure capable of rolling.
[0063] like Figure 2 A second test paper support column C21 is disposed outside the tested paper storage space C2, and a rolling device C211 is disposed on the second test paper support column C21. In this embodiment, the second test paper support column C21 is used to provide support for the tested paper. On the one hand, this ensures more stable sample dripping and detection during the test paper extension process; on the other hand, the rolling device is provided to reduce friction when the test paper passes through, preventing friction and damage to the test paper caused by the sealing sleeve inlet. The rolling device can be configured as a sleeve, a steel ball bearing structure, or other structure capable of achieving rolling.
[0064] like Figure 2In addition to the first and second test paper support columns C13 and C21, several other test paper support columns are provided along the test paper extension path to adjust the test paper extension path. In this embodiment, the untested paper storage space and the tested paper storage space are arranged horizontally and side by side. The test paper extends from the outlet C12 below the closed sleeve of the untested paper storage space, passes through the first test paper support column C13, passes through the third test paper support column C14 above the closed sleeve C11 of the untested paper storage space, passes through the fourth support column C15 located transversely to the third test paper support column and above the tested paper storage space C2, and finally passes through the second support column C21 to enter the tested paper storage space C2. A drop sampling device and an automatic urine collection and testing device are placed between the third and fourth support columns C14 and C15 to implement drop sampling and testing of urine.
[0065] In other embodiments, different support columns can be used to control the extension direction of the untested paper, thereby further reducing the size of the device or changing its shape. For example, in another embodiment, the untested paper storage space C1 and the tested paper storage space C2 are arranged vertically, or other arrangements are used, and different support columns are used to plan the extension of the test paper path to achieve the same effect.
[0066] like Figure 4 The untested paper storage space C1 and the tested paper storage space C2 are arranged horizontally side by side. The untested paper outlet C12 is positioned downward. A waste liquid guide trough C4 is provided between the untested paper storage space C1 and the tested paper storage space C2; the waste liquid guide trough C4 is positioned vertically downward. A tested paper sealing sleeve C22 is provided above the tested paper storage space, and a test paper inlet C23 is provided on the tested paper sealing sleeve. A second test paper support column is provided on one side of the test paper inlet C23.
[0067] In this embodiment, the closed sleeve C11 of the untested paper storage space and the tested paper storage space C22 are used to form a waste liquid guide groove C4 for draining out the urine sample that has dripped and overflowed and for cleaning the waste liquid in the sampling pump, thereby keeping the interior of the device clean and dry.
[0068] The "transverse direction" mentioned in the present invention refers to a direction with the direction of gravity as the longitudinal direction, a direction perpendicular to the longitudinal direction, or a direction with an angle within a range of 45-135 degrees with the longitudinal direction.
[0069] The “below” or “down” mentioned in the present invention refers to the direction of gravity or a direction slightly deviated from the direction of gravity.
[0070] The “above” or “upper” mentioned in the present invention refers to a direction that is the same as or slightly deviates from the opposite direction of gravity.
[0071] like Figures 3 to 6More specifically, the rotating shaft C3 in the middle of the tested paper storage space is connected to the stepping motor C5; an elastic tensioning mechanism is provided outside the untested paper storage reel structure for tensioning the test paper.
[0072] In this embodiment, the stepper motor C5 is connected to the rotating shaft C3 of the tested paper storage space to realize the automatic retraction of the tested paper of the urine detection and collection device. At the same time, in order to better realize urine detection and collection, this embodiment also provides an elastic tensioning mechanism (not marked in the figure) placed in the untested paper storage space. The elastic tensioning mechanism here can be configured as a coil spring in this embodiment. In other embodiments, other elastic tensioning structures can also be used for tensioning the device.
[0073] like Figures 4 and 5 The tested paper storage space C2 and the untested paper storage space C1 are set in the test paper storage box C6, and the test paper storage box C6 is detachably connected to the shell.
[0074] like Figures 3 to 6 The test paper storage box C6 is provided with a tested paper flushing hole C61 on the side close to the tested paper storage space C2. The tested paper flushing hole C61 is provided on the side of the test paper inlet C23 and is separated from the test paper to be tested and the test paper color recognition system; a waste liquid outlet C62 is provided below the test paper storage box C6. The waste liquid outlet C62 here can be directly hollowed out from the bottom wall of the test paper storage box C6 to facilitate the outflow of waste liquid.
[0075] like Figures 3 to 6 The interior of the shell also includes a fixing part A, which is provided with a semi-enclosed shell. The inner wall of the fixing part A is fixed with a sample drop device B1 and an automatic urine collection and detection device D in sequence.
[0076] The test paper storage box C6 is detachably arranged on the inner wall of the fixing part A. A sample drop detection hole C7 is provided on the side of the test paper storage box C6 facing the sample drop device B1 and the automatic urine collection and detection device D. The extension path of the test paper to be tested located in the test paper storage box C6 passes through the sample drop detection hole C7, which is used for test paper sample drop and detection.
[0077] Through the detachable connection between the fixing part A and the test paper storage box C6, the test paper storage box C6 can be quickly replaced. The motor and other integrated circuit control components are set on the fixing part, which can isolate the easily replaceable parts from the fixed parts, making it more convenient and quick.
[0078] Specifically, such as Figures 1 to 5 A flushing water inlet A1 is provided on one side of the fixing member A close to the tested paper flushing hole C61, a fixing member waste liquid outlet A2 is provided on the bottom wall of the fixing member, and a fixing member bottom wall A3 above the fixing member waste liquid outlet A2 is provided as a funnel structure.
[0079] The fixture waste liquid outlet A2 provided by the fixture can conveniently and quickly realize the flushing of the tested paper space, and the bottom wall A3 is provided as a funnel space, which can remove water in the device as much as possible to prevent water accumulation inside the device.
[0080] like Figure 3 Specifically, the test paper storage box C6 includes a first cover C63 and a second cover C64 that are detachably connected. A detachable handle C65 is provided on the outside of the first cover C63; the tested paper sealing sleeve and the to-be-tested paper sealing sleeve are provided on the first cover C63.
[0081] like Figure 6 In this embodiment, the first cover body C63 can be quickly disassembled through the detachable handle C65.
[0082] like Figures 3 to 6 More specifically, the fixing member A is provided with a motor C5 and a device control circuit board C8.
[0083] Example 3
[0084] like Figure 10 To better implement the functions of this device, in Example 3, this device also provides a test paper structure E, comprising several test sections E1, with a hollow structure E2 disposed between each adjacent test section E1. The test sections include a first detection identification point E11 and a second detection identification point E12, located at either end of the test section.
[0085] The setting of the detection identification points E11 and E12 enables the urine to accurately identify the start and end of the detection when the color detection is realized. At the same time, after the detection is completed, the hollow structure can be used to clean the urine detection collection device without contaminating other test papers. In this embodiment, the detection identification points can be uniformly black detection identification points when the test paper substrate is set to white, or white detection identification points can be used when the test paper substrate is set to black. In this embodiment, a third detection identification point E13 can be added. The third detection identification point E13 can use different colors to mark the specific position of the detection identification point in a roll of test paper. By analyzing the color of the soaked test paper, the third detection identification point E13 is analyzed at the same time to determine whether the test paper roll should be replaced or other functions should be realized. In other embodiments, the third detection identification point E13 can also be set or canceled according to actual conditions. The first and second detection and identification points use color blocks that are within a fourth range relative to the test paper substrate. The fourth range refers to the requirement for a sufficiently large color difference between the first and second detection and identification points and the substrate for accurate identification. Typically, this fourth range can have an RGB value of approximately 255. For example, a black block is used for a white substrate, and a white block is used for a black substrate. Of course, other fourth ranges can be used in other embodiments to achieve the same technical effect.
[0086] Example 4
[0087] like Figures 7 and 8 In order to better realize the functions of the automatic urine collection and detection device, the present device also provides an embodiment 4; the urine detection device in embodiment 4 is configured as a test paper color recognition system, the test paper color recognition system includes an LED irradiation lamp D1 and a color sensor, the color sensor is provided with an incident hole sleeve D3, and the LED irradiation lamp is configured as a white light source.
[0088] like Figure 9 The entrance aperture sleeve is configured as a quadrangular pyramid structure, with the entrance aperture located at the center of the pyramid structure. This allows for the center of the color sensor to be focused. This creates a small hole in front of the color sensor, making color acquisition more focused and stable. The entrance aperture also directionally narrows the color sensor's field of view, enabling more focused detection on a given amount of test paper, thereby saving test paper.
[0089] The quadrangular pyramid structure of the inlet cannula saves materials and simplifies production. Compared to other existing structures, the quadrangular pyramid structure is easier to manufacture, more stable, and saves materials. Furthermore, a color sensor socket slot is located above the inlet cannula, allowing it to be securely attached to the sensor, making urine testing more reliable.
[0090] In other embodiments, the entrance hole casing may also be configured as other structures to achieve the same function.
[0091] Example 5
[0092] To better illustrate the present invention, the present invention further provides an embodiment 5:
[0093] like Figure 11 In Example 5, specifically, the automatic urine collection and detection device as described above is included, and the automatic urine collection and detection device performs urine detection according to the following steps:
[0094] (1) Receive the start-up detection instruction of the detection drive device and start the detection;
[0095] (2) Performing a white balance operation on the color sensor;
[0096] (3) determining whether the first detection identification point of the test paper is detected, and if so, starting the color detection sensor to start collecting the test paper color data;
[0097] (4) determining whether the second detection identification point of the target section is detected, and if so, the test paper color data collection is completed;
[0098] If not, continue to collect color data until the second detection identification point of the target section is detected.
[0099] In this embodiment, the first detection identification point and the second detection identification point can be set respectively according to the color of the test paper substrate. For example, when the test paper substrate is white, the first detection identification point and the second detection identification point can be set to black respectively; when the test paper substrate is set to black, the first detection identification point and the second detection identification point can be set to white.
[0100] In this embodiment, the following steps are also included:
[0101] (41) detecting a third detection identification point of the section to be tested;
[0102] (42) According to the third detection identification point of the test paper, the position of the test section relative to the end or the starting end of the test paper is detected.
[0103] The third detection identification point here is set in the section to be tested. Each section to be tested is set with a unique third detection identification point, which is detected together with the color of the test paper after immersion. The test results are used to determine the distance between the section to be tested and the end or starting end of the test paper.
[0104] Specifically, the color detection sensor collects R, G, and B data respectively. After the collection is completed, the data is processed according to the following steps:
[0105] (5) The R, G, and B data are formed into three data sets, and the data in the data sets are sorted by time;
[0106] (6) A certain amount of data is taken from each data set in the order of the serial numbers to form a data group, and the range between the data in the data group is found to be greater than the first range; if the range is less than or equal to the first range, the group of data is discarded and the next group of data is judged; the first range here is the minimum difference between the RGB value corresponding to the color closest to white among the colors that may appear in the measured indicator and the RGB value of white. In this embodiment, the minimum difference between the RGB value of the color closest to white and the RGB value of white among the measured indicators is 30. In other embodiments, the size of the first range can be adjusted according to different indicators to be measured to achieve more accurate data screening.
[0107] The reason for determining the range of the data set is that in order to identify the urine test data, we need to find the trough of the data set on the white test paper to achieve data screening. Therefore, we use the range to determine whether the data set has a trough. Of course, in other embodiments, we can also use black test paper to find the peak of the data set. The range can also be used for judgment.
[0108] The data volume here can be selected as an appropriate data volume, such as 20 data as a group; the data here can be comprehensively judged by other data volumes collected based on color detection, and in other embodiments can also be increased or decreased according to the actual amount of data collected.
[0109] (7) If the range is greater than the first range, the minimum value and the corresponding serial number in the data group are output, and then the next group of data is determined. If the minimum value is repeated, it is output simultaneously. In this embodiment, the minimum serial number of the next group of data differs from the minimum serial number of the previous group of data by 4 serial number units or 5 serial number units. This is considered in consideration of the amount of calculation and the comprehensiveness of the screened data. Of course, in other embodiments, the minimum serial number of the next group of data can also differ from the serial number of the previous group of data by 1 serial number unit. This increases the amount of calculation, but the screening is more comprehensive. If a larger serial number unit is selected, the amount of calculation can be reduced accordingly.
[0110] (8) The three data items R, G, and B are respectively given a number of minimum values and serial numbers. The serial numbers corresponding to the minimum values are screened to see if there are any data with serial numbers that differ by a second range. If so, the minimum value among the serial numbers with the smallest difference is taken and the serial number corresponding to the point is output. The rest of the data is discarded. If the serial numbers corresponding to the output minimum value are repeated, they are output at the same time. The second range here is the difference between the minimum serial numbers of the two adjacent groups of data mentioned above.
[0111] Step (8) is to prevent multiple data from being selected in a certain downward trend curve. Therefore, for the data whose serial numbers corresponding to the minimum values of this batch differ from each other in the second range, the minimum value is taken and the rest are discarded. The second range here can be implemented by 4 or 5. In other embodiments, the second range here can also be adjusted according to actual needs.
[0112] (9) Three groups of serial numbers corresponding to the RGB values are obtained, and repeated serial numbers in the three groups of serial numbers are removed to obtain one group of serial numbers; in step (9), repeated filtered data groups in the three groups of filtered data can be removed to further achieve data filtering.
[0113] (10) The serial numbers in step (9) are screened again. If the serial numbers differ within the third range, the RGB values and serial numbers within the third range are averaged, and the final serial numbers and RGB values are output.
[0114] Step (10) can filter out multiple troughs within the small serial number interval in the three RGB data. The serial number interval here is the "third range". In this embodiment, the third range can be set to about 3, so that multiple troughs within the 3 serial number intervals can be filtered out. In other embodiments, the third range can also be determined according to actual conditions.
[0115] (11) After data screening, several groups of RGB values and original serial numbers are obtained.
[0116] In this embodiment, fourteen groups of data may be selected to correspond to fourteen corresponding indicators according to the specific amount of data. In other embodiments, different data may be selected to correspond to different numbers of indicators in other ways.
[0117] Specifically, the automatic urine collection and detection device further includes the following steps to achieve the correspondence between the color data and the urine index data:
[0118] (12) Assign fourteen new serial numbers according to the original serial numbers, from small to large;
[0119] (13) The test results are obtained by comparing each set of RGB values with the standard values.
