[0002] Urine testing is a routine examination item for medical institutions to examine patients. By analyzing the patient's urine, the concentration of chemical components in the urine can be obtained, such as glucose, urine protein, pH value, occult blood, nitrite, bilirubin, urobilinogen, red blood cells, white blood cells, etc. The concentration of chemical components in human urine has a normal range. When the patient has a lesion or changes in eating habits, the chemical composition of the urine will also change accordingly, so the patient's health status can be judged by the concentration of chemical components in the patient's urine.

[0031] The first embodiment of the present invention relates to a urine analysis device for testing the urine of a user, such as Figure 1 As shown, the urine analysis device 10 is assembled in the toilet 20. For example, the urine analysis device 10 is fixed to the inner wall of the toilet 20 by bonding, so that the user's urine can be collected for testing every time the user uses the toilet.

[0032] Please refer to Figures 1 to 3 The urine analysis device 10 includes: a processor 1, a microfluidic chip 2, a shell and a plurality of reagent capsules 4. Figure 2 , Figure 3 The number of reagent capsules 4 is only schematically shown, and the number of reagent capsules 4 can be set as needed.

[0033] The processor 1 is electrically connected to the microfluidic chip 2 , a plurality of reagent capsules 4 are arranged on the microfluidic chip 2 , the processor 1 and the microfluidic chip 2 are arranged in a shell, an opening 31 for collecting urine is arranged on the shell, and a reaction chamber 21 is arranged in the microfluidic chip 2 .

[0034] The reagent capsule 4 is used to store detection reagents.

[0035] The processor 1 is used to control the urine and the detection reagents in the multiple reagent capsules 4 to flow into the reaction chamber 21 of the microfluidic chip 2 in sequence for reaction when the urine enters the urine analysis device.

[0036] The microfluidic chip 2 is used to perform optical detection on the mixed liquid in the reaction chamber 21 after the inflowing urine reacts with the detection reagent in the reaction chamber 21 to obtain detection data.

[0037] The processor 1 is also used to receive a plurality of detection data returned by the microfluidic chip 2 to obtain urine analysis data.

[0038] A plurality of reagent capsules 4 are installed on a plurality of reagent inlets on the microfluidic chip 2. When each reagent capsule 4 is installed on the microfluidic chip 2, the detection reagent in the reagent capsule 4 can be controlled to flow into the reaction chamber 21 in the microfluidic chip 2 through the valve 201 on the microfluidic chip 2. The opening or closing of the valve 201 in the microfluidic chip 2 can be controlled by the processor 1. For example, each valve 201 is connected to a circuit board 202 having a control circuit, and a circuit board 203 on which the processor 1 is installed is connected to the circuit board 202, so that the processor 1 can be connected to the control circuit on the circuit board 202 to control the opening and closing of each valve 201. It should be noted that the circuit board 202 and the circuit board 203 in this embodiment also include peripheral circuits, interfaces and other components, which will not be described one by one here.

[0039] The housing includes an upper housing 32 and a lower housing 33 fixed together, an opening 31 is provided on the upper housing 32, and the lower housing 33 is fixed on the inner wall of the toilet. The portion of the lower housing 33 fixed to the inner wall of the toilet can be provided with a flexible material with a changeable shape, such as silica gel, so that the urine analysis device can be applied to toilets of various shapes. A filter net can be provided to cover the opening 31 to prevent solid matter from flowing into the urine analysis device and affecting the urine analysis results.

[0040] When the user uses the toilet, the user's urine flows into the urine analysis device through the opening 31 on the upper shell 32, and the processor 1 inputs the urine into the microfluidic chip 2 in multiple times based on the items to be tested. When each item of urine is tested, the corresponding detection reagent is allowed to flow into the reaction chamber 21 of the microfluidic chip 2 by controlling the valve to open, so that the urine flowing into the reaction chamber 21 can react chemically with the detection reagent.

[0041] The microfluidic chip 2 has an optical detection function. For example, an optical detection module 204 is provided in the microfluidic chip 2. The optical detection module 204 can perform optical detection on the mixed liquid after the reaction of urine and the detection reagent in the reaction chamber 21 to obtain detection data; the optical detection module 204 is connected to the circuit board 202, and the processor 1 can be connected to the optical detection module 204 through the control circuit on the circuit board 202, so that the processor 1 can control the urine and the detection reagent to flow into the reaction chamber 21 each time, and after a certain reaction time, control the optical detection module 204 to perform optical detection on the mixed liquid in the reaction chamber 21. The detection data obtained by the optical detection module 204 can also be sent to the processor 1. After the detection of multiple items is completed, the processor 1 summarizes the detection data of multiple detection items in this urine detection, and then obtains the urine analysis data of this urine detection based on these multiple detection data.

[0042] In one example, the urine analysis device is also provided with a wireless communication module (not shown in the figure, the wireless communication module can be installed on the circuit board 203), such as WIFI, 4G, 5G, etc., so that the processor 1 can be connected to the cloud server by wireless, and the urine analysis data obtained from each urine test is sent to the cloud server, and the cloud server monitors the urine analysis data of the user for a long period of time, such as 7 days, 15 days, 30 days, etc. In addition, the user can also connect electronic devices such as mobile phones and computers to the urine analysis device, so that the processor 1 can also send the urine analysis data to the user's electronic device, so that the user can view his own urine analysis data in real time and view his own physical condition through the urine analysis data.

[0043] In this embodiment, different types of detection reagents can be respectively contained in multiple reagent capsules 4, and the types of detection reagents can be set according to the detection items of urine. For example, the detection reagents used for urine creatinine detection are creatinine colorimetric solution and creatinine analysis buffer solution; the detection reagent used for urine protein detection is sulfosalicylic acid solution; the detection reagent used for urine pH detection is bromothymol blue solution; the detection reagent used for urine ketone body detection is 10% concentration of ferric chloride; the detection reagent used for vitamin C detection is acid buffer solution, phenanthroline colorimetric solution and VC analysis buffer solution; the detection reagent used for urine nitrite detection is Griess solution; it should be noted that the above only lists some detection items and the required detection reagents, and the detection items can be increased or decreased as needed, such as adding the detection of urine albumin and urine hemoglobin.

[0044] It should be noted that the urine analysis device in this embodiment may also include a battery holder (not shown in the figure), which is connected to the circuit board 202. When the battery is installed in the battery holder, the battery can power the processor 1 in the urine analysis device and the optical detection module 204, valve 201, etc. in the microfluidic chip 2. In addition, the urine analysis device in this embodiment may also include a residual sensor for detecting the residual amount of the detection reagent in each reagent capsule 4, and each residual sensor is connected to the processor 1, so that the processor 1 can issue a prompt in time when the residual amount of the detection reagent in any reagent capsule 4 is insufficient. The reminder method is, for example, sending a prompt message through a cloud server or directly to the electronic device of the connected user.

[0045] Compared with the prior art, this embodiment provides a urine analysis device that can be installed in a toilet. The urine analysis device includes a processor, a microfluidic chip, a shell, and a plurality of reagent capsules. When a user uses the toilet, urine flows into the urine analysis device through an opening on the urine analysis device. The processor can control the urine and the detection reagents in the plurality of reagent capsules to flow into the reaction chamber of the microfluidic chip in sequence for reaction. The microfluidic chip can perform optical detection on the mixed liquid in the reaction chamber after the urine in the reaction chamber reacts with the detection reagent to obtain detection data, and send the detection data to the processor. After the plurality of detection reagents in the plurality of reagent capsules react with the urine respectively, a plurality of detection data can be obtained. The processor can obtain the urine analysis data of the user based on the plurality of detection data. In the present invention, the urine analysis device installed in the toilet can perform optical detection and analysis of a plurality of items of urine of the user in the daily life of the user to obtain the urine analysis data of the user, and then analyze the health status of the user according to the urine analysis data of the user, so that when the user's body has not yet shown any abnormality, the user can make a prediction through the change of the urine condition, and can predict in advance whether there is a problem with the health status of the user to a certain extent.

[0046] The urine analysis device in this embodiment can analyze the correlation data between the user's metabolism and the user's daily behavior state based on the urine analysis data collected continuously and for a long time. For example, the user's eating habits (including meals, nutrition, vitamins, tobacco and alcohol, etc.), disease conditions, work and rest rules, exercise habits, sleep status or medication status and other behavioral states will all be presented in the user's urine. When certain behavioral states of the user change, it will have a corresponding impact on the user's urine. The urine analysis device can also detect the changes in urine, and then the urine analysis device can analyze the correlation between the user's metabolism and the user's behavior state based on long-term and continuous urine analysis data.

[0047] The second embodiment of the present invention is a urine analysis device. The main difference between this embodiment and the first embodiment is that: Figure 4 and Figure 5 The urine analysis device also includes: a peristaltic pump 5, a urine storage 6 and a waste liquid storage 7.

[0048] One end of the urine storage 6 is connected to an opening 31 (not shown) on the shell, and is used to store urine flowing into the urine analysis device. The microfluidic chip 2 is provided with a urine inlet 22, and the other end of the urine storage 6 is connected to the urine inlet 22 on the microfluidic chip 2.

[0049] The peristaltic pump 5 is fixed on the microfluidic chip 2 ( Figure 4In the example, the peristaltic pump 5 is fixed to the microfluidic chip 2 through the circuit board 202, one end of the peristaltic pump 5 is connected to the liquid outlet 23 on the microfluidic chip 2, and the other end of the peristaltic pump 5 is connected to the waste liquid storage 7. A waste liquid outlet can also be provided on the housing, and the waste liquid storage 7 is connected to the waste liquid outlet through a waste liquid pipeline. After the waste liquid storage 7 is full, the waste liquid can flow out of the urine analysis device through the waste liquid pipeline. In addition, the urine storage 6 is connected to the waste liquid outlet through a urine discharge pipeline. After the urine storage 6 is full, the excess urine can flow out of the urine analysis device through the urine discharge pipeline.

[0050] The urine storage 6 is used to store urine that has flowed into the urine analysis device.

[0051] The processor 1 is used to control the peristaltic pump 5 to pump out urine of a first preset proportion from the urine storage 6 to the reaction chamber 21 .

[0052] The processor 1 is used to control the peristaltic pump 5 to pump out a detection reagent of a second preset ratio from the reagent capsule 4 to the reaction chamber 21 .

[0053] The processor 1 is also used to control the peristaltic pump 5 to pump the reacted mixed liquid out of the reaction chamber 21 to the waste liquid storage 7 .

[0054] In one example, the urine analysis device further includes: a cleaning pump 8 and a cleaning liquid storage 9. The cleaning pump 9 is fixed on the circuit board 202, the cleaning liquid storage 9 is connected to the cleaning liquid connection port 24 on the microfluidic chip 2, one end of the cleaning pump 8 is connected to the cleaning inlet 25 on the microfluidic chip 2, and the other end of the cleaning pump 8 is connected to the cleaning outlet 26 on the microfluidic chip 2. The cleaning pump 8 can be a diaphragm pump.

[0055] The cleaning liquid storage 9 is used to store the cleaning liquid. The cleaning liquid can be clean water or other solvents with cleaning function.

[0056] The processor 1 is used to control the cleaning pump 8 to pump out cleaning liquid from the cleaning liquid storage 9 to clean the reaction chamber 21 of the microfluidic chip 2 after receiving the detection data of the reaction of the current detection reagent and urine returned by the microfluidic chip 2, and control the cleaning pump 8 to pump out the cleaned liquid from the reaction chamber 21.

[0057] The processor 1 is used to control urine and the next detection reagent to flow into the reaction chamber 21 of the microfluidic chip 2 for reaction after the reaction chamber 21 of the microfluidic chip 2 is cleaned.

[0058] In one example, the microfluidic chip 2 is further provided with an air inlet 27 and a vent 28 .

[0059] The urine inlet 22, liquid outlet 23, cleaning liquid connection port 24, cleaning inlet 25, cleaning outlet 26, air inlet 27 and ventilation port 28 on the microfluidic chip 2 are all opened or closed by corresponding valves (the valve setting method is similar to the valve 201 in the first embodiment and will not be repeated here); each valve is connected to a circuit board 202 with a control circuit, and the processor 1 is connected to the control circuit on the circuit board 202 through the circuit board 203, so that the opening and closing of each valve can be controlled.

[0060] In this embodiment, when no urine enters the urine analysis device, except for the valve corresponding to the air vent 28 on the microfluidic chip 2, which is in an open state, all other valves are in a closed state. When urine enters the urine storage device 6 in the urine analysis device through the opening 31 on the shell, the processor 1 controls the valve corresponding to the air vent 28 to close, and controls the valve corresponding to the urine inlet 22 to open, controls the peristaltic pump 5 to pump out a first preset proportion of urine from the urine storage device 6 to the reaction chamber 21, and then closes the valve corresponding to the urine inlet 22, and then controls the valve corresponding to the reagent capsule 4 of the current detection item to open, and controls the peristaltic pump 5 to pump out a second preset proportion of detection reagent from the reagent capsule 4 to the reaction chamber 21, and then closes the valve corresponding to the reagent capsule 4; at this time, the detection reagent reacts with the urine in the reaction chamber 21, and the processor 1 controls the optical detection module 204 in the microfluidic chip 2 to pump out a first preset proportion of urine from the urine storage device 6 to the reaction chamber 21, and then closes the valve corresponding to the urine inlet 22. The mixed liquid after the reaction of urine and the detection reagent in the reaction chamber 21 is optically detected, and the optical detection module 204 sends the detection data obtained by the optical detection to the processor 1. The processor 1 determines that the current detection project is completed, and first controls the peristaltic pump 5 to pump out the mixed liquid after the reaction from the reaction chamber 21 to the waste liquid storage 7; then, controls to open the valves of the cleaning liquid connection port 24 and the cleaning inlet 25, and controls the cleaning pump 8 to pump out the cleaning liquid from the cleaning liquid storage 9 to clean the reaction chamber 21 of the microfluidic chip 2, and then closes the valves of the cleaning liquid connection port 24 and the cleaning inlet 25; then opens the valve of the cleaning outlet 26, controls the cleaning pump 8 to pump out the cleaning liquid in the reaction chamber 103, and then closes the valve of the cleaning outlet 26, and then opens the corresponding valve of the air inlet 27, and the cleaning pump 8 pumps air to discharge and dry the liquid in the reaction chamber 21, and then closes the corresponding valve of the air inlet 27. Then the processor 1 performs the detection of the next detection item, controls the valve corresponding to the urine inlet 22 to open, controls the peristaltic pump 5 to pump out the first preset proportion of urine from the urine storage 6 to the reaction chamber 21, and then closes the valve corresponding to the urine inlet 22, and then controls the valve corresponding to the reagent capsule 4 of the next detection item to open, and controls the peristaltic pump 5 to pump out the second preset proportion of detection reagent from the reagent capsule 4 to the reaction chamber 21, and then closes the valve corresponding to the reagent capsule 4, and repeats the above process to complete the optical detection. After each detection item is completed, the reaction chamber 21 is cleaned, and then the next detection item is detected after cleaning, until all detection items are completed, the processor 1 summarizes the detection data of multiple detection items in this urine detection, and then obtains the urine analysis data of this urine detection based on these multiple detection data.

[0061] In this embodiment, the types of detection reagents in multiple reagent capsules correspond one-to-one to multiple second preset ratios, that is, based on different detection items, the amount of detection reagents required each time is different. Therefore, the processor 1 controls the peristaltic pump 5 to pump out different reagents from different reagent capsules 4 into the reaction chamber 21 in different ratios, so as to avoid the amount of detection reagents affecting the detection data of optical detection, thereby ensuring the accuracy of urine analysis to a certain extent.

[0062] In one example, a temperature sensor (not shown in the figure) is also provided in the urine analysis device. The temperature sensor is provided at the opening 31 or at a position near the opening 31 in the housing, and is connected to the circuit board 203, so that the processor 1 is electrically connected to the temperature sensor through the circuit board 203. When no user uses the toilet 20, the temperature detected by the temperature sensor is the indoor temperature, and the indoor temperature value is sent to the processor 1; when a user uses the toilet 20, urine flows into the urine analysis device from the opening 31, and the temperature sensor detects the user's urine temperature value, and sends the detected urine temperature value to the processor 1. The urine temperature value is greater than the indoor temperature. The processor 1 determines that the detected temperature value increases, and the difference between the urine temperature value and the indoor temperature value is greater than or equal to the preset first temperature threshold, and determines that urine is detected to flow into the urine analysis device. The processor 1 controls the urine analysis device to enter the detection state, and wakes up the microfluidic chip 2 to perform urine detection. Among them, the first temperature threshold is, for example, 2 degrees, 5 degrees, 10 degrees, etc.

[0063] In one example, the processor 1 is also used to control the urine analysis device to enter a standby state after receiving multiple detection data returned by the microfluidic chip 2 and obtaining urine analysis data, if the temperature value sent by the temperature sensor is lowered and the temperature reduction value is greater than or equal to a preset second temperature threshold. Specifically, when the urine test is completed, if the user flushes at this time, the temperature sensor detects the water temperature value and sends it to the processor 1. The water temperature value sent by the temperature sensor received by the processor 1 is less than the urine temperature value. It is determined that the temperature has dropped and the temperature reduction value is greater than or equal to the preset second temperature threshold, indicating that the user has finished using the toilet. The urine analysis device is controlled to enter a standby state again, thereby reducing the power consumption of the urine analysis device. The second temperature threshold is, for example, 2 degrees, 5 degrees, 10 degrees, etc.

[0064] In one example, the processor 1 is also used to adjust the first temperature threshold and the second temperature threshold according to the currently detected temperature value when the temperature value sent by the temperature sensor remains unchanged within a preset time. Specifically, when the user has not used the toilet for a long time, the temperature detected by the temperature sensor at this time is the indoor temperature at this time. Since the indoor temperature changes with the seasons, and the human urine temperature is basically maintained constant, the first temperature threshold and the second temperature threshold can be adjusted in real time according to the indoor temperature value. For example, in summer, the indoor temperature is higher, and the temperature difference between the indoor temperature and the urine temperature decreases, and the first temperature threshold and the second temperature threshold can be appropriately reduced; in winter, the indoor temperature is lower, and the temperature difference between the indoor temperature and the urine temperature increases, and the first temperature threshold and the second temperature threshold can be appropriately increased.

[0065] The third embodiment of the present invention relates to a urine analysis device. The main difference between this embodiment and the first embodiment is that: Figure 6 The urine analysis device further includes: a power supply receiving module 101 and a power supply 102 , and the power supply receiving module 101 is connected to the processor 1 and the microfluidic chip 2 respectively.

[0072] The fourth embodiment of the present invention relates to a urine analysis method, which is applied to the urine analysis device of any one of the first to third embodiments.

[0073] The specific process of the urine analysis method of this embodiment is as follows Figure 8 shown.

[0074] Step 101, when urine enters the urine analysis device, the processor controls the urine and the detection reagents in the multiple reagent capsules to flow into the reaction chamber of the microfluidic chip in sequence for reaction.

[0075] Specifically, when the user uses the toilet, the user's urine flows into the urine analysis device through the opening 31 on the upper shell 32, and the processor 1 inputs the urine into the microfluidic chip 2 in multiple times based on the items to be tested. When testing each item of the urine, the corresponding detection reagent is allowed to flow into the reaction chamber 21 of the microfluidic chip 2 by controlling the valve to open, so that the urine flowing into the reaction chamber 21 can react chemically with the detection reagent.

[0076] In one example, the urine analysis device may be the urine analysis device in the second embodiment, such as Figure 4 and Figure 5 As shown; at this time, the processor 1 controls the peristaltic pump 5 to pump out the first preset ratio of urine to the reaction chamber 21, and controls the peristaltic pump 5 to pump out the second preset ratio of detection reagent from the reagent capsule 4 to the reaction chamber 21. Specifically, when no urine enters the urine analysis device, except for the valve corresponding to the air vent 28 on the microfluidic chip 2, all other valves are in a closed state. When urine enters the urine storage 6 in the urine analysis device through the opening 31 on the shell, the processor 1 controls the valve corresponding to the air vent 28 to close, and controls the valve corresponding to the urine inlet 22 to open, controls the peristaltic pump 5 to pump out the first preset ratio of urine from the urine storage 6 to the reaction chamber 21, and then closes the valve corresponding to the urine inlet 22, and then controls the valve corresponding to the reagent capsule 4 of the current detection item to open, and controls the peristaltic pump 5 to pump out the second preset ratio of detection reagent from the reagent capsule 4 to the reaction chamber 21, and then closes the valve corresponding to the reagent capsule 4.

[0077] Step 102 : After the urine flowing in reacts with the detection reagent in the reaction chamber, the microfluidic chip performs optical detection on the mixed liquid in the reaction chamber to obtain detection data.

[0078] Step 103: The processor receives multiple detection data returned by the microfluidic chip to obtain urine analysis data.

[0079] Specifically, the microfluidic chip 2 has the function of optical detection. For example, an optical detection module 204 is provided in the microfluidic chip 2. The optical detection module 204 can perform optical detection on the mixed liquid after the reaction of urine and the detection reagent in the reaction chamber 21 to obtain detection data; the processor 1 can be connected to the optical detection module 204 through the control circuit on the circuit board, so that the processor 1 can control the urine and the detection reagent to flow into the reaction chamber 21 each time, and after a certain reaction time, control the optical detection module 204 to perform optical detection on the mixed liquid in the reaction chamber 21. The detection data obtained by the optical detection module 204 can also be sent to the processor 1. After the detection of multiple items is completed, the processor 1 summarizes the detection data of multiple detection items in this urine detection, and then obtains the urine analysis data of this urine detection based on these multiple detection data.

[0080] In one example, after step 103, the method further includes:

[0081] Step 104: The processor uploads the urine analysis data to the cloud server.

[0082] Specifically, the urine analysis device is also provided with a wireless communication module, such as WIFI, 4G, 5G, etc., so that it can be connected to the cloud server wirelessly and send the urine analysis data obtained from each urine test to the cloud server. The cloud server monitors the user's urine analysis data for a long period of time, such as 7 days, 15 days, 30 days, etc.
