Abstract
Description
Technical Field
[0001] This invention belongs to the field of smart toilet technology, specifically relating to a smart toilet for health monitoring. Background Technology
[0002] The rapid development of home technology and home health management concepts has made smart toilets with human excrement health monitoring functions an important home medical auxiliary device. These smart toilets can efficiently collect urine samples non-invasively during daily toilet use and quickly complete the detection of multiple physiological indicators, providing users with early health risk screening and early warning services.
[0003] Among them, the sampling device, as the core functional module of the health monitoring smart toilet, directly determines the reliability of the test results and the long-term stability of the equipment through its sampling accuracy, thoroughness of cleaning, and standardized sample processing. Although traditional sampling device flushing solutions can meet basic cleaning needs in the short term, after long-term use, trace amounts of residue gradually accumulate in the sampling pipeline and cavity, which may eventually lead to sudden anomalies in the test data.
[0004] Most mainstream smart toilets operate on a single-sample, instant-detection, and instant-disposal model. In this model, the smart toilet only collects the amount of sample needed for a single test, and any excess sample is immediately flushed away. However, if the device malfunctions or the sampling pipeline becomes contaminated, retesting and verification are impossible because no original sample is retained.
[0005] More importantly, many pathological indicators in human urine have a significant transient characteristic. For example, microscopic hematuria caused by early-stage urinary tract tumors, abnormal urinary ketone bodies in the early stages of diabetic ketoacidosis, and intermittent proteinuria caused by latent nephritis often appear only in a single urine sample within a specific time period. By the time a sample is taken again, the indicators may have returned to normal. Because retesting is not possible after the data is abnormal, the actual existence of the abnormal indicators cannot be confirmed. This directly leads to the complete neglect of early warning signals of these latent, progressive diseases, missing the best opportunity for intervention and treatment, and causing irreversible and serious damage to the user's health.
[0006] Therefore, in view of the above-mentioned technical problems, it is necessary to provide a smart toilet for health monitoring.
[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0023] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.
[0024] like Figures 1-2 As shown, an embodiment of the present invention provides a smart toilet for health monitoring, including a toilet body 1. The upper part of the toilet body 1 has a toilet bowl for users to use, and the bottom of the toilet bowl is connected to a sewage pipe. After the user finishes using the toilet, the excrement in the toilet bowl is completely discharged through the sewage pipe through the siphon effect.
[0025] More specifically, the toilet body 1 is rotatably connected to a seat ring 2 and a lid 3. The seat ring 2 is used to provide human support when the user is using the toilet. In existing conventional solutions, the seat ring 2 also generally integrates conventional functional components such as a heating module, a human proximity sensing module, and an electrocardiogram measurement mechanism 4 to improve user comfort and the intelligence level of the device. The lid 3 is used to seal the toilet bowl when the toilet is not in use to prevent the spread of odors and isolate pollution.
[0026] To achieve non-invasive urine health indicator testing, smart toilets with health monitoring functions now integrate a main detection unit on the toilet body 1. The main detection unit includes at least a first detection chamber 5, a main sampling mechanism 6, and a main delivery mechanism. The first detection chamber 5 is equipped with a test strip carrier station, on which test strips matching the testing items are placed.
[0027] In actual use, the main sampling mechanism 6 collects fresh urine samples during the user's urination process. The urine is then transported to the first testing chamber 5 by the main delivery mechanism and quantitatively added to the test strip. Inside the first testing chamber 5, the optical detection module collects the color development image of the test strip, and the built-in calibration algorithm analyzes and processes the color development data to finally output the corresponding health test data, thus completing a single health test process.
[0028] To address the issue that existing smart toilets for health monitoring cannot retest and verify abnormal test results based on original urine samples from the same batch, such as... Figures 1-7 As shown, the main inspection sampling mechanism 6 includes a sampling valve 7. A blind hole 101 is provided on the toilet body 1. The sampling valve 7 is slidably connected inside the blind hole 101. The outer diameter of the sampling valve 7 is smaller than the inner diameter of the blind hole 101. A guide ring 702 that matches the inner wall of the blind hole 101 is fixedly connected to the sampling valve 7. The guide ring 702 and the blind hole 101 are coaxially arranged. The sampling valve 7 can be slidably connected along the opening direction of the blind hole 101 through the guide ring 702.
[0029] Specifically, such as Figure 4As shown, a first magnetic block 10 is fixedly connected to the bottom of the sampling valve 7, a sealing element 8 is fixedly connected to the bottom of the blind hole 101, and a first electromagnetic block 9 is fixedly connected inside the sealing element 8. The first electromagnetic block 9 changes its own magnetic polarity by switching the current direction of its power supply coil, thereby achieving magnetic attraction or repulsion with the first magnetic block 10, thus controlling whether the sampling valve 7 slides outward or inward.
[0030] A plug 701 is fixedly connected to one end of the sampling valve 7 near the toilet bowl. In the initial state, the plug 701 is used to block the entrance of the blind hole 101. The blind hole 101, the sampling valve 7, and the plug 701 enclose a sample retention chamber. The re-inspection unit includes a re-inspection sampling mechanism 29 and a second detection chamber 26. A second cavity 103 is provided on the toilet body 1. The re-inspection sampling mechanism 29 is installed in the second cavity 103. The second detection chamber 26 is fixedly connected to the toilet body 1 and its position matches that of the second cavity 103. A sampling channel 105 is provided between the second cavity 103 and the sample retention chamber. The re-inspection sampling mechanism 29 takes out the sample from the sample retention chamber through the sampling channel 105 and moves it to the test strip in the second detection chamber 26.
[0031] Because the sample retention chamber is set at an angle, when the sampling valve 7 is opened for sampling, the urine sample flows in along the direction of the blind hole 101, and some of the urine sample enters the main inspection delivery mechanism directly from the sampling valve 7.
[0032] like Figures 3-7 As shown, the re-inspection sampling mechanism 29 includes a second slide rail 30, which is arranged along the length of the second cavity 103. The second detection chamber 26 and the sampling channel 105 are located at the two ends of the second slide rail 30, respectively. In this embodiment, the sampling channel 105 is defined as being located on the left side of the second slide rail 30, and the second detection chamber 26 is located on the right side of the second slide rail 30. A second electric slider 31 is slidably connected to the second slide rail 30, and a second electric push rod 32 is fixedly connected to the second electric slider 31. A U-shaped part 33 is slidably connected to the output shaft of the second electric push rod 32. The U-shaped part 33 includes an upper plate, a lower plate, and a side plate, which are integrally formed. The upper plate is slidably connected to the output shaft of the second electric push rod 32, and the lower plate is clamped to a secondary inspection sampling tube 35. An airbag 36 is fixedly connected to the upper end of the secondary inspection sampling tube 35, and the airbag 36 and the secondary inspection sampling tube 35 are connected.
[0033] In actual use, the second electric slider 31 slides along the second slide rail 30 and slides to the left side of the second slide rail 30. The second electric push rod 32 is activated, allowing the auxiliary sampling tube 35 to pass through the sampling channel 105 and enter the sample retention chamber. When the lower plate contacts the lower end face of the second chamber 103, the U-shaped part 33 stops moving downward, and the output end of the second electric push rod 32 continues to move downward and squeezes the airbag 36. After the compression is in place, the second electric push rod 32 retracts. When it begins to retract, the position of the U-shaped part 33 remains unchanged under the action of gravity, and the airbag 36 returns to its original shape, allowing the urine sample in the sample retention chamber to be sucked in through the auxiliary sampling tube 35. Due to the negative pressure, the urine sample can be fixed inside the auxiliary sampling tube 35.
[0034] like Figure 6 As shown, a limiting plate 34 is fixedly connected to the side wall of the second cavity 103. The limiting plate 34 has a second U-shaped groove 3401 that matches the auxiliary sampling tube 35. When the auxiliary sampling tube 35 is completely located in the second cavity 103, the second electric slider 31 slides to the right to the top of the second detection chamber 26. At this time, the auxiliary sampling tube 35 is stuck in the second U-shaped groove 3401. The second electric push rod 32 moves downward, the position of the U-shaped part 33 does not change, the airbag 36 is squeezed, and the urine sample fixed in the auxiliary sampling tube 35 drips onto the test strip located in the second detection chamber 26.
[0035] It is worth noting that a first U-shaped groove 3301 is provided on the lower plate, and a pair of retaining rings 3501 are fixedly connected to the auxiliary sampling tube 35. The retaining rings 3501 hold the auxiliary sampling tube 35 in the first U-shaped groove 3301 on the lower plate and can also be held in place by the limiting plate 34. The auxiliary sampling tube 35 and the airbag 36 are used as consumables. The disposable sampling device can completely avoid the error problem of test results caused by sample residue and crystallization in the main inspection conveying mechanism. In daily use, the main inspection conveying mechanism and the first inspection chamber 5 are used for testing. During retesting, the disposable sampling device and the second inspection chamber 26 are used for testing, which can greatly reduce the operating cost of the smart toilet. When the user has doubts about the test results, the retesting results are obtained through retesting. The initial test results and the retesting results are compared. The two sets of independent test data can be cross-verified, completely dispelling the user's doubts about the test results and increasing the user's trust.
[0036] like Figure 10 As shown, the second cavity 103 has an opening in the middle, which is used for disassembling and assembling the auxiliary sampling tube 35.
[0037] like Figures 4-5As shown, in order to ensure the sealing of the end of the sampling channel 105 connected to the sample retention chamber, an installation hole 106 is provided on the toilet body 1. A sealing mechanism 37 is installed in the installation hole 106. When the sealing mechanism 37 is in the closed state, it can completely block the end of the sampling channel 105 connected to the sample retention chamber and cut off the connection between the two.
[0038] Specifically, the blocking mechanism 37 includes a pair of blocking blocks 38, which are slidably connected to each other within the mounting hole 106. A guide rod 39 is fixedly connected to the inner wall of the mounting hole 106. A guide groove 3801 matching the guide rod 39 is provided on the blocking block 38, and the blocking block 38 slides along the direction of the guide rod 39 through the guide groove 3801. A second magnetic block 41 is fixedly connected to the blocking block 38, and a second electromagnetic block 40 matching the second magnetic block 41 is fixedly connected to the inner wall of the mounting hole 106. The second electromagnetic block 40 can change its own magnetic polarity by switching the current direction of its power supply coil, thereby achieving magnetic attraction or repulsion with the second magnetic block 41, thus driving the blocking block 38 to slide along the direction set by the guide rod 39, realizing the switching between the sampling channel 105 and the sample retention chamber.
[0039] In practical applications, to prevent urine samples from contaminating the inner wall of the sampling channel 105, the sealing block 38 is generally positioned higher than the inner wall of the blind hole 101, allowing the outer wall of the sealing block 38 to be exposed within the blind hole 101. This arrangement allows for cleaning of the outer wall of the sealing block 38 during the cleaning of the blind hole 101, as the mating surface of the sealing block 38 does not contact the urine sample, thus minimizing contamination.
[0040] In this embodiment, the toilet body 1 has a built-in data monitoring module, which receives health test data and determines its authenticity. First, it receives test data uploaded from the first testing chamber 5, and automatically filters out invalid data through a preprocessing program. If no valid data can be obtained, the data monitoring module will directly determine that the testing process is abnormal. For valid data, the data monitoring module compares it with preset standard ranges and personal historical baselines, and judges it according to three levels: when the indicator falls into the pathological range, it is marked as pathological abnormal; when the indicator is in the borderline range or fluctuates more than 50% from the personal baseline, it is marked as borderline abnormal; when the data shows physiological contradictions or irregular large fluctuations, it is judged as distorted abnormal.
[0041] Once any anomaly detection is triggered, the smart toilet will immediately lock the original sample from the same batch within the sampling chamber and simultaneously activate the re-inspection sampling mechanism 29 for re-inspection. By cross-referencing the main inspection data and the re-inspection data, the smart toilet can confirm the authenticity of the anomaly and simultaneously output corresponding warning information or operation prompts.
[0042] like Figures 1-11As shown, the main inspection conveying mechanism includes a first conveying pipe 11, which is connected to the sampling valve 7. The first conveying pipe 11, located between the sampling valve 7 and the sealing element 8, is an elastic pipe. A first conveying pump 12 is installed on the first conveying pipe 11. The first conveying pump 12 draws the sample from the sampling valve 7 under negative pressure and conveys it to the multi-port pipe 13. A second conveying pipe 15 is installed at one end of the multi-port pipe 13, and the sample is then conveyed to the first detection chamber 5 through the second conveying pipe 15.
[0043] like Figures 10-11 As shown, the toilet body 1 has a first cavity 102, and a shifting assembly 18 is installed inside the first cavity 102. The shifting assembly 18 includes a first slide rail 19, which is fixedly connected to one side wall of the first cavity 102. A first electric slider 20 is slidably connected to the first slide rail 19, and a mounting plate 21 is fixedly connected to the first electric slider 20. The output end of the second delivery pipe 15 is fixedly connected to the mounting plate 21. In other words, the position of the output end of the second delivery pipe 15 can be changed. During sample delivery, the second delivery pipe 15 is aligned with the position of the first detection chamber 5. During cleaning, the output end of the second delivery pipe 15 is staggered with the first detection chamber 5, preventing sewage from contaminating the space inside the first detection chamber 5.
[0044] The output end of the second delivery tube 15 is fixedly connected to the first tube body 16, which is fixedly connected to the mounting plate 21. The inner wall of the first tube body 16 is slidably connected to the second tube body 17. A main sampling tube 22 is detachably installed between the first detection chamber 5 and the first cavity 102. The second tube body 17 matches the input end of the main sampling tube 22. The front end of the second tube body 17 is fixedly connected to the connecting plate 1701. A first electric push rod 1702 matching the connecting plate 1701 is fixedly connected to the mounting plate 21. The output end of the first electric push rod 1702 is fixedly connected to the connecting plate 1701. When the first electric push rod 1702 is activated, it can push the second tube body 17 to slide inside the first tube body 16, forcing the second tube body 17 to dock with the main sampling tube 22. After the main sampling tube 22 and the second tube body 17 are docked, the main sampling tube 22 can deliver the urine sample to the test strip in the first detection chamber 5.
[0045] The main sampling tube 22 is detachably fixed between the first cavity 102 and the first detection chamber 5, serving as a connection channel between the first cavity 102 and the first detection chamber 5. The first cavity 102 is used as a consumable and can be fixedly connected between the first cavity 102 and the first detection chamber 5 by means of threaded connection. The output end of the first cavity 102 is aligned with the test strip.
[0046] Specifically, a drain pipe 23 is fixedly connected to the toilet body 1. The input end of the drain pipe 23 is on the same horizontal plane as the input end of the main inspection sampling pipe 22. A solenoid valve 24 is installed on the drain pipe 23, and a first one-way valve 25 is fixedly connected to the output end of the drain pipe 23. During sewage discharge, the first electric push rod 1702 retracts, the first electric slider 20 moves towards the drain pipe 23, and after the second pipe body 17 is aligned with the drain pipe 23, the first electric push rod 1702 is activated, forcing the second pipe body 17 and the drain pipe 23 to connect. Cleaning fluid is introduced from the multi-port pipe 13, and sewage can be discharged through the output end of the second delivery pipe 15 and the second pipe body 17. That is, the main inspection delivery mechanism delivers cleaning fluid from the middle to both ends to achieve cleaning of the main inspection delivery mechanism and avoid the situation where the test results are affected by scale, residue, etc. inside the main inspection delivery mechanism due to substandard cleaning.
[0047] like Figures 8-10 As shown, the output end of the drain pipe 23 is located inside the toilet bowl, and the first one-way valve 25 is used to prevent sewage from the toilet bowl from entering the drain pipe 23.
[0048] like Figure 8 As shown, multiple quick-connect pipes 14 are fixedly connected to the multi-port pipe 13. The multiple quick-connect pipes 14 are used to connect cleaning fluid, washing fluid, drying gas, antibacterial gas, etc.
[0049] In this embodiment, four quick-connect pipes are included. The first quick-connect pipe 14 is connected to the medical-grade neutral enzyme cleaning solution supply unit and is used to perform enzymatic cleaning of the main test delivery pipeline after a single test, decomposing organic contaminants such as urine crystals and protein residues attached to the inner wall, and eliminating the risk of test distortion caused by residues. The second quick-connect pipe 14 is connected to the sterile deionized pure water supply unit and is used to high-pressure flush the pipeline after cleaning, thoroughly draining residual cleaning solution and contaminants to avoid affecting the subsequent color development reaction of the test strip.
[0050] The third quick-connect pipe 14 is connected to the sterilized and filtered clean dry gas supply unit. The dry gas dew point is ≤-40℃. After rinsing with pure water, it continuously delivers high-pressure dry gas into the pipeline, blowing away any residual liquid droplets on the inner wall throughout the process, ensuring that the pipeline cavity is completely dry and preventing the growth of bacteria and the formation of biofilm in a humid environment. The fourth quick-connect pipe 14 is connected to the antibacterial gas supply unit, which uses food-grade slow-release chlorine dioxide antibacterial gas that meets home safety standards. After the pipeline is completely dry, it delivers a quantitative amount of antibacterial gas into the pipeline and holds it at a preset pressure for a set time to disinfect the inner wall of the pipeline in all directions without dead angles. At the same time, it forms a temporary antibacterial protective layer to inhibit the risk of microbial contamination and cross-infection during long-term use by the main inspection and transportation mechanism.
[0051] like Figures 12-13As shown, during the cleaning process, since the cleaning fluid is output from the middle of the main inspection and conveying mechanism to both ends, a drain channel 104 matching the blind hole 101 is provided on the toilet body 1. A second one-way valve 27 is fixedly connected to one end of the drain channel 104 near the blind hole 101, and a third one-way valve 28 is fixedly connected to one end of the blind hole 101 near the toilet bowl. The second one-way valve 27 ensures that the liquid sample inside the blind hole 101 will not enter the drain channel 104 under normal pressure, and the third one-way valve 28 ensures that the sewage in the toilet bowl will not enter the drain channel 104.
[0052] In actual use, the high-pressure cleaning fluid is transported in the reverse direction along the main inspection conveying mechanism to the inner cavity of the sampling valve 7, and then sprayed out from the sampling valve 7 toward the outlet end of the retention chamber in a high-pressure jet state. During the spraying process, a stable high-pressure state is maintained. The high-pressure fluid forms an all-round turbulent flow field in the closed retention chamber, continuously flushing the outer wall of the sampling valve 7, the sealing end face of the plug 701, and the inner wall surface of the blind hole 101, achieving thorough cleaning of the entire flow channel of the main inspection conveying mechanism. After cleaning, the waste liquid is discharged into the toilet bowl through the drain hole 104, and then discharged with the toilet siphon sewage process. The other end of the main inspection conveying mechanism is connected to the drain pipe 23, and the sewage after flushing is also discharged into the toilet bowl.
[0053] Preferably, to further improve the cleaning efficiency and thoroughness of the sample retention chamber, several sets of flow-guiding ribs are integrally formed on the inner wall of the sample retention chamber. The flow-guiding ribs are arranged in a spiral continuous pattern along the axial direction of the blind hole 101, with the flow-facing surface of the ribs facing the cleaning fluid injection end of the sampling valve 7, and the flow-facing surface is machined into an arc-shaped flow-guiding surface. When the high-pressure cleaning fluid is injected into the sample retention chamber, the flow-guiding ribs can guide the high-pressure fluid to form a stable vortex along the circumference of the sample retention chamber, prolonging the residence time of the high-pressure fluid in the sample retention chamber and significantly enhancing the flushing force of the fluid on the inner wall of the chamber and the outer wall of the sampling valve 7. Simultaneously, it can guide the high-pressure fluid to flush the sealing gap between the plug 701 and the bottom of the blind hole 101, the fitting gap between the sampling valve 7 and the inner wall of the blind hole 101, and other conventional cleaning dead zones. Furthermore, the spiral flow-guiding ribs can also play a stabilizing role during the urine sampling stage, preventing the formation of eddies and bubbles in the urine sample within the sample retention chamber and ensuring the accuracy of the sample volume.
[0054] To maintain user trust in the detection data over a long period of time, such as Figures 14-15As shown, the toilet body 1 is also equipped with a calibration mechanism 42. The calibration mechanism 42 includes a liquid storage tank 43 installed on the back of the toilet body 1. The liquid storage tank 43 is filled with test samples. The concentrations of core detection indicators such as urine protein, urine glucose, urine occult blood, pH value, and white blood cells in the test samples are all preset fixed values. The performance is stable within the shelf life and is completely matched with the flow characteristics and color reaction characteristics of real urine, ensuring that the self-test results can truly reflect the actual working state of the system. A second delivery pump 44 is fixedly connected to the upper end of the liquid storage tank 43. A third delivery pipe 45 is installed between the second delivery pump 44 and the liquid storage tank 43. A fourth delivery pipe 46 is fixedly connected to the output end of the second delivery pump 44. A guide channel 201 matching the sampling valve 7 is opened on the seat ring 2. The outlet end of the guide channel 201 is located above the sampling valve 7, and a fourth one-way valve 47 is fixedly connected to the outlet end of the guide channel 201. The fourth delivery pipe 46 is connected to the sampling valve 7.
[0055] The user can activate the calibration mechanism 42, inputting the test sample from the output end of the guide channel 201 into the sampling valve 7 to perform the full-process testing. After the test is completed, the data monitoring module compares and calculates the actual test data of this self-test with the pre-stored standard values of the standard test sample. If the deviations of the actual test values of all test indicators from the standard values are within the preset allowable error range, a prompt indicating that the system cleanliness is qualified will be output to the user. If the deviation of any test indicator exceeds the allowable error range, it will be determined that there is urine residue, crystallization or microbial contamination in the flow channel, which will cause the standard test sample to be contaminated and the test results to deviate. At this time, an early warning of abnormal system cleanliness will be pushed to the user, and a cleaning program will be automatically triggered. After cleaning, a second simulation test can be performed until the system cleanliness meets the standard. If the simulation test exceeds 3 to 5 times, the cleaning program will be stopped and a maintenance prompt will be pushed to the user.
[0056] In this invention, the working process of the smart toilet is as follows: In the initial state of the equipment, the first electromagnetic block 9 and the first magnetic block 10 are magnetically attracted to each other, the sampling valve 7 retracts into the blind hole 101, and the plug 701 completely blocks the entrance of the blind hole 101; the pair of plugging blocks 38 of the plugging mechanism 37 are connected to each other to completely block the sampling channel 105 and cut off the connection between the sample retention chamber and the second chamber 103.
[0057] During urination, the first electromagnetic block 9 switches the direction of its power supply current, changing its magnetic polarity and generating a repulsive force with the first magnetic block 10. This drives the sampling valve 7 to slide outward along the blind hole 101, causing the plug 701 to leave the entrance of the blind hole 101, and urine to flow into the blind hole 101. A portion of the urine enters the inner cavity of the sampling valve 7 as the primary sample, while the remaining portion is retained in the retention cavity formed by the inner wall of the blind hole 101, the outer wall of the sampling valve 7, and the plug 701, thus completing the sampling of the same batch of urine. After sampling, the first electromagnetic block 9 switches its magnetic polarity again, restoring its magnetic attraction with the first magnetic block 10, causing the sampling valve 7 to retract, and the plug 701 to reseal the entrance of the blind hole 101. The retention cavity then forms a closed space, locking in the urine sample from this urination.
[0058] The main sampling mechanism 6 activates the first delivery pump 12, which pumps the urine sample from the sampling valve 7 under negative pressure through the first delivery tube 11 into the multi-port tube 13, and then through the second delivery tube 15 into the first cavity 102. The shifting component 18 drives the output end of the second delivery tube 15 to align with the main sampling tube 22, and the first electric push rod 1702 pushes the second tube 17 to extend and seal with the main sampling tube 22. The urine sample is then quantitatively dripped onto the test strip in the first testing chamber 5 through the main sampling tube 22. After the test strip completes the color reaction, the optical detection module built into the first testing chamber 5 acquires the color image of the test strip, converts it into quantitative health test data through a calibration algorithm, and transmits it to the data monitoring module in real time, completing a single main inspection process.
[0059] After receiving the master inspection data, the data monitoring module first performs preprocessing to remove invalid data, and then performs a three-level anomaly judgment on the valid data against the preset standard range and the user's personal historical test baseline. When any judgment result of pathological abnormality, borderline abnormality, or data distortion abnormality is triggered, the closed-loop re-inspection process is immediately executed: The second electromagnetic block 40 switches the magnetic polarity, driving a pair of blocking blocks 38 to separate and opening the sampling channel 105; the re-inspection sampling mechanism 29 starts, the second electric slider 31 slides along the second slide rail 30 to above the sampling channel 105, the second electric push rod 32 extends downward, driving the disposable auxiliary inspection sampling tube 35 through the sampling channel 105 and inserting it into the sample retention cavity; when the U-shaped piece 33 contacts the lower end face of the second cavity 103, the second electric push rod 32 continues to descend and compress. The airbag 36 is then pushed back, and the airbag 36 returns to its original state, generating negative pressure to draw the original urine sample in the sample retention chamber into the secondary sampling tube 35. The second electric slider 31 moves the secondary sampling tube 35 to above the second testing chamber 26, and the secondary sampling tube 35 is inserted into the second U-shaped groove 3401 of the limiting plate 34. The second electric push rod 32 descends again to squeeze the airbag 36, quantitatively adding the urine sample onto the new test strip in the second testing chamber 26, completing the retest.
[0060] After receiving the re-examination data, the data monitoring module cross-compares it with the main examination abnormality data. If the deviation between the two sets of data is within the allowable range, the abnormality is confirmed as a genuine pathological abnormality, and a graded health warning and medical advice are pushed to the user. If the deviation exceeds the threshold, the main examination abnormality is confirmed as a distortion caused by pipeline contamination, and a detection abnormality prompt is pushed to the user and a cleaning procedure is triggered to avoid misjudgment of health. After the re-examination is completed, the re-examination sampling tube 35 can be directly replaced to prevent cross-contamination.
[0061] Once the main inspection and re-inspection processes are completed and there is no need to retain the samples, the system will automatically trigger the cleaning procedure.
[0062] It is worth noting that if the sample needs to be preserved, the auxiliary sampling tube 35 can be removed through the opening in the middle of the second cavity 103 without performing the re-inspection.
[0063] Finally, the smart toilet can automatically start a self-test program according to a preset cycle: the second delivery pump 44 of the calibration mechanism 42 starts, pumping the standard test sample of known concentration in the storage tank 43 into the sampling valve 7 through the third delivery pipe 45 and the fourth delivery pipe 46, executing the complete sampling and testing process. The data monitoring module compares the actual test data with the preset standard value of the standard test sample. If the deviation is within the allowable range, the system cleanliness and testing accuracy are deemed qualified; if the deviation exceeds the threshold, it is determined that there is residual pollution in the flow channel, and the entire cleaning process is automatically triggered. After cleaning, a second retest is automatically performed. If the test still fails to meet the standard after multiple consecutive tests, a device maintenance reminder is pushed to the user, realizing closed-loop management of the system status.
[0064] The beneficial effects of this invention include at least the following: A closed sampling chamber is formed by the blind hole 101, sampling valve 7, and plug 701. During a single urine sampling process, the collection of the main test sample and the closed storage of the original urine sample from the same batch are completed simultaneously, eliminating the need for the user to perform a second urine sampling. Even if the main test data is abnormal, a retest can be performed directly based on the stored original sample. This perfectly solves the industry problem in existing technologies where intermittent and transient pathological indicators in urine have returned to normal by the time of a second sampling, making retesting impossible. It identifies early abnormal signals in a single urine sample, effectively avoiding missed warning signals of occult and progressive diseases, and providing users with the best opportunity for intervention and treatment.
[0065] Routine testing is completed using the main inspection delivery mechanism and the first testing chamber 5. The retesting process is completed using a disposable auxiliary inspection sampling tube 35 and the second testing chamber 26. The retesting process does not pass through the main inspection delivery pipeline, thus avoiding interference from residual, crystallized, and biofilm contamination in the main inspection delivery mechanism on the retesting results. By cross-comparing the two sets of independent test data, it is possible to distinguish between real pathological abnormalities and test distortions caused by equipment contamination, thereby avoiding misjudgment.
[0066] The retesting process uses a 35mm auxiliary sampling tube, which is disposable after use, eliminating the risk of cross-infection of bodily fluids between different test batches and different family members. After cleaning, a drying and antibacterial process is provided to form a long-lasting antibacterial protective layer on the inner wall of the tube, eliminating the common industry problems of bacterial growth and mold growth in humid environments, which produce odors. It fully meets the biosafety requirements of home medical auxiliary devices, greatly improving users' trust in the test results and acceptance of the product.
