Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urine detection, in particular to a rotating wheel type urine detection device and a urine detection toilet. BACKGROUND

[0002] With the continuous improvement of people's health awareness, more and more health detection devices have entered the household product industry. For example, some intelligent toilets currently support urine detection function. Reasonable urine detection can detect early symptoms of diseases, thereby achieving the goal of monitoring human health at all times, reducing the probability of disease occurrence, reducing personal medical expenses, and reducing the pressure of medical institutions.

[0003] At present, the urine detection device applied to the intelligent toilet is mostly in the form of reagent strips. Each urine detection is completed by a specific action mechanism to "take" and "recycle or discard" the reagent strip. A multi-axis stepper motor is usually used to perform three-dimensional movement, thereby completing the "taking and placing" action of the reagent strip. On the one hand, the action mechanism is complicated in design, complex in structure, large in size, poor in stability, and low in work efficiency, which greatly reduces the user experience. On the other hand, the arrangement of the reagent card occupies a large space, which is difficult to meet the family use demand. For example, the reagent card is arranged in a planar disc shape in cooperation with the motor. However, the planar projection area is large, which will affect the opening size of the integrated structure for taking and placing the reagent card, and the overall space occupation is large, which is not conducive to the extreme miniaturization. SUMMARY

[0004] The main purpose of the present application is to provide a rotating wheel type urine detection device, a urine detection toilet and a detection method, which aims to solve the technical problem of large space occupation of the urine detection device in the prior art.

[0005] In order to achieve the above purpose, the present application provides a rotating wheel type urine detection device, which comprises a rotating wheel type reagent card, a sample injection mechanism, a driving mechanism and a collection and detection unit. The collection and detection unit comprises a signal collection module, and the sample injection mechanism comprises a sample injection needle.

[0006] The rotating wheel type reagent card comprises a rotating drum and a plurality of reagent strips, and the plurality of reagent strips are arranged on the drum wall of the rotating drum. When the rotating wheel type reagent card is detachably sleeved on the driving mechanism, the driving mechanism drives the rotating wheel type reagent card to rotate.

[0007] When the rotary reagent card rotates the test strip to the injection station, the injection needle moves towards the injection station and inserts into the injection port of the test strip, injecting the urine sample into the test strip. After injection, the injection needle moves upward, and the rotary reagent card rotates the injected test strip to the signal acquisition station, where the signal acquisition module acquires signals from the injected test strip. Alternatively, after injection, the signal acquisition module directly acquires signals from the injected test strip.

[0008] Furthermore, all of the plurality of reagent strips are disposed along the axial direction of the rotating cylinder on the inner or outer wall of the rotating cylinder.

[0009] Furthermore, the acquisition and detection unit also includes a control module, which is electrically or communicatively connected to the signal acquisition module, and is used to receive the detection data acquired by the signal acquisition module and process the detection data;

[0010] The signal acquisition module includes a CCD camera, a CMOS camera, or a color sensor, and the distance between the signal acquisition module and the test strip is within a specified focal length range.

[0011] Alternatively, the signal acquisition module includes a CIS sensor, the distance between the CIS sensor and the reagent strip is within the focal length range of the linear array scanning, and when acquiring detection data, the rotary reagent card is driven to rotate at a specified linear speed to achieve linear array scanning;

[0012] Alternatively, the signal acquisition module includes an electrochemical small signal acquisition module and an electrical connector. The electrical connector is electrically connected to the electrochemical small signal acquisition module and is located on the injection needle. When the injection needle moves down to inject the sample, the electrical connector contacts the reaction liquid in the test strip and forms an electrical connection between the electrochemical small signal acquisition module and the test strip.

[0013] Furthermore, the driving mechanism includes a mounting base, a driving assembly, and a fixed cylinder disposed on the driving assembly. The driving assembly is disposed on the mounting base. When the rotary reagent card is fitted inside the inner wall of the fixed cylinder, the driving assembly drives the fixed cylinder to rotate, thereby driving the rotary reagent card to rotate.

[0014] Furthermore, the injection mechanism also includes a support and an injection drive motor, a first pulley, a second pulley, a lead screw, and an intermediate connecting member respectively mounted on the support;

[0015] The bracket is fixedly installed on the mounting base. The output end of the injection drive motor is connected to the first pulley. The first pulley is connected to the second pulley through a transmission belt. The second pulley drives the lead screw to rotate. The intermediate connecting piece is sleeved on the lead screw and connected to the injection needle. When the lead screw rotates, it drives the intermediate connecting piece to move up or down, and drives the injection needle to move up or down.

[0016] Furthermore, the injection mechanism is located inside the fixed cylinder, and the injection point corresponds to the injection port of the reagent strip located at the bottom. The support extends outward to form a fixed block, and the signal acquisition module is fixedly installed on the fixed block and is directed towards the detection position of the reagent strip located at the bottom.

[0017] Furthermore, it also includes a zero-finding switch, which includes a position detection sensor and a position detection sensor triggering device. The position detection sensor is fixedly disposed on one side of the fixed cylinder, and the position detection sensor triggering device is disposed on the outer wall of the fixed cylinder. One end of the rotating cylinder is provided with a notch. When the fixed cylinder rotates so that the position detection sensor is aligned with the position detection sensor triggering device, the notch is exactly aligned with the injection needle.

[0018] Furthermore, it also includes a buffer bottle, which is located below the rotary reagent card, and the opening of the buffer bottle corresponds to the position of the injection needle.

[0019] The present invention also provides a urine testing toilet, including a toilet body and the aforementioned rotary urine testing device, wherein the rotary urine testing device is installed in the toilet body.

[0020] The present invention also provides a detection method, which employs the rotary urine detection device described above to implement the method, the method comprising:

[0021] S1: Rotate the rotary reagent card to rotate the test strip to the injection station;

[0022] S2: Drive the injection needle downwards by a specified step length and insert it into the injection port of the test strip to inject the urine sample in the injection needle into the test strip;

[0023] S3: After injection, the injection needle moves upward and rotates the injected reagent strip to the signal acquisition station via the rotary reagent card. The signal acquisition module then acquires the signal from the injected reagent strip. Alternatively, after injection, the signal acquisition module directly acquires the signal from the injected reagent strip and sends it to the control module for further analysis and processing.

[0024] The rotary urine testing device provided by this invention uses reagent strips arranged on the wall of a rotating cylinder. Rotation switches the reagent strip positions, enabling a comprehensive and accurate urine testing process. The entire structure eliminates the need for "picking up" and "placing" reagent strips; simple rotation switches the reagent strip positions and completes urine sampling and signal acquisition and analysis, making the overall urine testing process simpler and more efficient. Furthermore, the simple structure makes the device more stable and cost-effective. The reagent strips are arranged directly along the cylinder wall, leaving the interior of the cylinder for other necessary structural components. The small overall projected area saves space, facilitating miniaturization and integration into various types of toilets, maximizing its commercial value. Attached Figure Description

[0035] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0036] Reference Figures 1-6 The rotary urine testing device provided by this invention can be applied to home urine testing. Specifically, the rotary urine testing device includes a rotary reagent card 1, a sample injection mechanism, a drive mechanism, and a data acquisition and detection unit. The data acquisition and detection unit includes a signal acquisition module 41 for acquiring urine test data. Specifically, it includes a signal acquisition sensor and a corresponding analog-to-digital conversion circuit system, such as a CIS or CCD, CMOS camera for image recognition, a color sensor for color recognition, or an electrochemical acquisition module for small electrochemical signal acquisition. The signal acquisition module 41 is used to acquire and digitize the biochemical and electrochemical signals after the reaction between the reagent and urine to facilitate further data analysis and processing.

[0037] In this embodiment, the rotary reagent card 1 can be cylindrical, such as cylindrical or polygonal cylindrical, etc., which is not limited here. The rotary reagent card 1 includes a rotating cylinder 12 and a plurality of reagent strips 11 that carry reagents and can react with urine. The reagent strips 11 are disposed on the cylinder wall of the rotating cylinder 12, which can be disposed on the inner wall of the rotating cylinder 12 or on the outer wall of the rotating cylinder 12, which can be disposed according to the actual space, which is not limited here.

[0038] In this embodiment, the injection mechanism is used to inject samples into the reagent strip 11. Specifically, it includes an injection needle 21, which corresponds to an injection station. The injection station is used to determine the position for injecting samples into the reagent strip 11. When the injection port 110 of the reagent strip to be tested is rotated to a position below the injection needle 21, the injection needle 21 faces the injection port 110 of the reagent strip to be tested. At this time, the injection port 110 of the reagent strip to be tested is located at the injection station. The injection needle 21 can move up and down, inserting into the injection port 110 or moving away from the injection port 110.

[0039] The signal acquisition module 41 can be located inside or outside the rotary reagent card 1, preferably inside the rotary reagent card 1, corresponding to the signal acquisition station. When the reagent strip undergoing the reaction is located at the signal acquisition station, the signal acquisition module 41 acquires the signal from the reagent strip undergoing the reaction. In one embodiment, the injection station and the signal acquisition station are at different horizontal levels. After the injection port 110 of the test reagent card is rotated to the injection station and the injection needle 21 moves down and inserts into the injection port 110 to complete the injection, the drive mechanism rotates the rotary reagent card 1 at a certain angle, causing the test reagent strip to rotate to the signal acquisition station, and the signal acquisition module 41 completes the signal acquisition. In another embodiment, the signal acquisition station and the injection station are at the same horizontal level, and sampling can be performed directly without rotating the rotary reagent card 1 after the injection is completed.

[0040] The drive mechanism is used to drive the rotary reagent card 1 to rotate. Specifically, a stepper motor and multiple sets of gears can be used to achieve precise rotational motion control. When the rotary reagent card 1 is detachably fitted onto the drive mechanism, the drive mechanism drives the rotary reagent card 1 to rotate. When the injection port 110 of the test strip rotates to the injection position of the corresponding injection needle 21, the injection needle 21 moves to the injection position and inserts into the injection port 110 of the test strip for injection. This causes the test strip to rotate to the signal acquisition position of the corresponding signal acquisition module 41. After a certain biochemical reaction time, the signal acquisition module 41 collects data and transmits the collected detection data to the control module for further processing.

[0041] The aforementioned rotary urine testing device uses reagent strips 11 arranged on the wall of a rotating cylinder 12. Rotation switches the positions of the reagent strips 11, enabling a comprehensive and accurate urine testing process. The entire structure eliminates the need for manual "pick-up" and "place" mechanisms for the reagent strips 11; simple rotation is sufficient to switch the strips and complete urine sampling and signal acquisition and analysis. This makes the overall urine testing process simpler and more efficient. Furthermore, the simple structure makes the device more stable and cost-effective. The reagent strips 11 are directly arranged along the wall of the rotating cylinder 12, allowing the interior of the cylinder to accommodate other structural components. The smaller overall projected area saves space, facilitating miniaturization and integration into various types of toilets, thus maximizing its commercial value.

[0042] In this embodiment, multiple reagent strips 11 are arranged along the axial direction of the rotating drum 12 on the drum wall. They can be evenly spaced or non-uniformly arranged according to actual needs, such as by type or region. In another embodiment, the reagent strips 11 are provided in various types, such as dry chemical reagent strips, immunochromatographic reagent strips, immunofluorescence reagent strips, or electrochemical sensor reagent strips. One or more types of reagent strips 11 can be combined and arranged as needed, and rotated to different positions by the rotating drum 12 to realize multi-index urine detection. For example, five diabetes test reagent strips and five routine urine test reagent strips are provided.

[0043] In one embodiment, the aforementioned rotary reagent card 1 can be used as a consumable, that is, when all the reagent strips 11 in the rotary reagent card 1 are used up, it can be discarded directly and a new rotary reagent card 1 can be replaced. In another embodiment, the reagent strips 11 are detachably connected to the rotating cylinder 12, and when the reagent strips 11 in the rotary reagent card 1 are used up, the reagent strips 11 can be replaced directly without replacing the rotary reagent card 1.

[0044] In one embodiment, the acquisition and detection unit further includes a control module, which is electrically or communicatively connected to the signal acquisition module 41. The control module is used to receive the detection data acquired by the signal acquisition module 41 and process the detection data. The detection data can be the reaction signal or data of the test strip 11. Specifically, the control module includes a main controller and a wireless communication module connected to the main controller. It may also include peripheral circuits. The main controller can realize the logic control of the overall urine detection process and the analysis and processing of sampling data. The wireless communication module can realize communication interaction with external devices, such as data interaction with a host computer or the cloud.

[0045] The signal acquisition module 41 includes a CCD camera or a CMOS camera or a color sensor, or a CIS sensor, or an electrochemical small signal acquisition module and an electrical connector, such as an electrochemical sensor and an acquisition circuit.

[0046] It is worth noting that, since the rotary reagent card 1 is arranged in a cylindrical shape in practical applications, such as a cylinder or a regular polygonal cylinder, if the signal acquisition module 41 uses a CCD, CMOS camera or color sensor, when collecting the color change after the reagent reacts with urine, the reagent strip 11 needs to be arranged directly below the signal acquisition module 41 and a reasonable acquisition focal length needs to be ensured. That is, the distance between the signal acquisition module 41 and the test reagent strip is within the specified focal length range, so as to directly collect the color change of the reagent.

[0047] If the signal acquisition module 41 uses a CIS sensor for linear array scanning, it needs to drive the rotary reagent card 1 to rotate at a specified linear speed. At this time, the focal length from the surface of the reagent strip 11 to the scanning line of the CIS sensor lens changes. The CIS sensor needs to select a reasonable focal length range to ensure that the spacing of the linear array scanning is within the focal length range when the reagent strip 11 rotates. The spacing between the CIS sensor and the reagent strip 11 is set within the focal length range of the linear array scanning, thereby realizing linear array scanning.

[0048] If the signal acquisition module 41 adopts an electrochemical small signal acquisition module, then the signal acquisition module 41 and the reagent strip 11 need to be effectively electrically connected. At this time, the signal acquisition module 41 is installed on the injection mechanism, and an effective electrical connector, such as a pogo-pin, is installed on the injection mechanism. The injection needle 21 moves downward, and the electrical connector contacts the reaction liquid in the test reagent strip 11, so that the electrochemical small signal acquisition module and the test reagent strip form an electrical connection, that is, directly trigger the electrical connection between the reagent strip 11 and the electrochemical sensor.

[0049] In another embodiment, the rotary reagent card 1 can be further equipped with an electronic information tag. Correspondingly, the signal acquisition module 41 can identify the electronic information tag, such as an RFID tag, an NFC tag, a one-dimensional or two-dimensional code, etc., to record necessary information such as the type, production date, expiration date, and usage status of the reagent strip 11.

[0050] In one embodiment, to further save space and improve cleanliness, reagent strips 11 are disposed on the inner wall of the rotating cylinder 12, with multiple reagent strips 11 arranged axially along the inner wall of the rotating cylinder 12. Specifically, the inner wall of the rotating cylinder 12 is provided with grooves, and the reagent strips 11 are adapted to be embedded in the grooves. Correspondingly, the sample injection mechanism can be centrally located inside the rotating cylinder 12, or on the side of the rotating cylinder 12, thereby minimizing space usage.

[0051] In one embodiment, refer to Figures 3-5 The driving mechanism includes a mounting base 31, a driving component 32, and a fixed cylinder 33 disposed on the driving component 32. A cavity for placing the aforementioned rotary urine detection device can be reserved inside the toilet. The opening of the cavity is adapted to the outer circumference of the rotary cylinder 12 or is slightly larger than the rotary cylinder 12. The fixed cylinder 33 corresponds to the opening position. The rotary cylinder 12 is inserted into the opening to fix the rotary cylinder 12 on the fixed cylinder 33. The mounting base 31 can be fixedly disposed on the cavity wall of the cavity. The driving component 32 is disposed on the mounting base 31. When the rotary reagent card 1 is fixedly fitted inside the inner wall of the fixed cylinder 33, the driving component 32 drives the fixed cylinder 33 to rotate, thereby driving the rotary reagent card 1 to rotate.

[0052] The fixed cylinder 33 may be equipped with a foolproof contact to ensure the uniqueness of the connection position of the rotary reagent card 1 in the fixed cylinder 33. When the fixed cylinder 33 rotates, it will drive the rotary reagent card 1 to rotate synchronously. In addition, the position of the rotary reagent card 1 inserted into the fixed cylinder 33 can be fixed by a buckle, or by the fixed protrusion of the rotary reagent card 1 cooperating with the fixed groove on the outer wall of the fixed cylinder 33. For ease of operation and identification, the relative positions of the two can be unique and fixed.

[0053] In this embodiment, refer to Figures 4-5 The drive assembly 32 includes a rotary drum drive motor 321, a drive bearing 322, a first gear 323, and a second gear 324. The rotary drum drive motor 321 is fixedly mounted on one side of the mounting base 31. The output end of the rotary drum drive motor 321 passes through the mounting base 31 and connects to the center of the first gear 323. The external teeth of the second gear 324 mesh with the external teeth of the first gear 323. One end of the fixed cylinder 33 is fixedly mounted on the second gear. The center of the fixed cylinder 33 can correspond to the center of the second gear 324. The drive bearing 322 is located between the fixed cylinder 33 and the second gear 324. When the rotary drum drive motor 321 drives the first gear 323 to rotate, the first gear 323 drives the second gear 324 to rotate, so that the second gear 324 drives the fixed cylinder 33 to rotate.

[0054] In one embodiment, the injection mechanism further includes a support 22 and an injection drive motor 23, a first pulley 24, a second pulley 25, a lead screw 26, and an intermediate connector 27, all respectively disposed on the support 22.

[0055] The bracket 22 is fixedly installed on the mounting base 31, with one end fixed on the mounting base 31 and the other end extending towards the rotating drum 12. The injection drive motor 23 is located at the top of the inner cavity of the bracket 22. The first pulley 24 and the second pulley 25 are both located above the bracket 22. The output end of the injection drive motor 23 passes through the bracket 22 and connects to the first pulley 24. The first pulley 24 is connected to the second pulley 25 through the transmission belt 20. The second pulley 25 drives the lead screw 26 to rotate. The top end of the lead screw 26 is connected to the second pulley 25. The lead screw 26 is limited and inserted into the bracket 22. A bearing is provided between the lead screw 26 and the bracket 22. When the second pulley 25 rotates, it can drive the lead screw 26 to rotate. The intermediate connecting piece 27 is sleeved on the lead screw 26 and connected to the injection needle 21. When the lead screw 26 rotates, it drives the intermediate connecting piece 27 to move up or down, and drives the injection needle 21 to move up or down. Specifically, the intermediate connector 27 is disposed in the inner cavity of the bracket 22. The intermediate connector 27 has a through hole, and a lead screw nut 28 is disposed in the through hole. The lead screw nut 28 is sleeved on the lead screw 26. When the lead screw 26 rotates, the lead screw nut 28 drives the intermediate connector 27 to move up and down because the lead screw 26 is limited. In another example, a thread adapted to the lead screw 26 can also be provided in the through hole of the intermediate connector 27 to achieve up and down movement.

[0056] Preferably, the injection mechanism further includes a guide shaft 29, the top end of which passes through the intermediate connector 27, and a linear bearing is provided between them. The bottom end of the guide shaft 29 passes through the bracket 22 and is connected to the injection needle 21, driving the injection needle 21 to move up and down. Furthermore, two guide shafts 29 are provided, which can be arranged side by side. The injection needle 21 can be connected to either guide shaft 29 as needed, or can be switched from one guide shaft 29 to another.

[0057] Preferably, a sampling needle zeroing component 5, such as a slotted photoelectric zeroing switch, can be provided on the inner cavity of the bracket 22. Specifically, it includes a sampling needle position sensor 51 and a sampling needle position triggering device 52. The sampling needle position triggering device 52 is set on the intermediate connector 27, and the sampling needle position sensor 51 is fixed on the inner cavity of the bracket 22. The position of the sampling needle 21 can be determined by the sampling needle zeroing component 5. At the same time, whenever a test is required, its position can be reset to zero, and then it can be adjusted up and down for sampling.

[0058] In one embodiment, when the reagent strip 11 is placed on the inner wall of the rotating cylinder 12, the injection mechanism is located inside the fixed cylinder 33. For example, one end of the bracket 22 is fixed to the mounting base 31, and the other end passes through the fixed cylinder 33. The injection needle 21 is located above the injection port 110 of the reagent strip 11 at the bottom. The bracket 22 extends outward to form a fixed block 42. At this time, the fixed block 42 is also located inside the rotating cylinder 12. The signal acquisition module 41 is fixedly set on the fixed block 42 and is directed to the detection position of the reagent strip 11 at the bottom. In this way, injection and signal acquisition can be achieved in the smallest possible space.

[0059] In another embodiment, when the reagent strip 11 is placed on the outer surface of the rotating cylinder 12, the injection mechanism is placed on the outside of the rotating cylinder 12, and at this time the outer support of the injection structure extends to the top of the rotating cylinder 12, so that the lower part of the external injection needle corresponds to the position of the reagent strip 11 at the top of the rotating cylinder 12. Correspondingly, an external signal acquisition module 41 is placed on the side of the external injection needle. The principle of the whole process is the same as that of the reagent strip 11 placed on the inner wall of the rotating cylinder 12.

[0060] In one embodiment, a zero-finding switch 6 is also included. The zero-finding switch 6 can be a Hall effect switch or a slotted photoelectric switch. The zero-finding switch 6 includes a position detection sensor 61 and a position detection sensor triggering device 62. If the zero-finding switch 6 is a slotted photoelectric switch, the position detection sensor triggering device 62 is an opaque baffle. The position detection sensor 61 is fixedly disposed on one side of the fixed cylinder 33, and the position detection sensor triggering device 62 is disposed on the outer wall of the fixed cylinder 33. One end of the rotating cylinder 12 is provided with a notch 10. When the rotating cylinder 12 is inserted into the fixed cylinder 33, the notch 10 is exactly... Corresponding to the positioning protrusion of the fixed cylinder 33, when the fixed cylinder 33 rotates and the position detection sensor 61 corresponds to the position detection sensor trigger device 62, the notch 10 exactly corresponds to the injection needle 21. The zero-finding switch 6, together with the drive mechanism, completes the determination of the zero position of the movement. At the same time, it facilitates the injection needle 21 to pass through the notch 10 and discharge unnecessary urine, such as the initial urine. In addition, the rotary reagent card 1 is provided with a white card strip for white balance calibration, which is used for white balance calibration of the image acquisition sensor. This white card strip can be set at the position of the reagent strip 11 groove corresponding to the notch 10.

[0061] In this embodiment, after power-on, the drive mechanism drives the rotary reagent card 1 to rotate in one direction, such as clockwise, until the zeroing switch 6 is triggered. At this time, the drive mechanism successfully finds the zero position, and the position of each reagent strip 11 is determined by the system. Preferably, the notch 10 on the rotary reagent card 1 is positioned at the injection station, that is, directly below the injection needle 21, so that the injection needle 21 can pass through the notch 10 and discharge urine downwards. Then, the signal acquisition module 41 reads the electronic tag information of the rotary reagent card 1 to determine the usage information of each reagent strip 11 on the rotary reagent card 1, including comprehensive urine test information, such as: customer information, reagent strip information, health management plan information, etc. Furthermore, it can also determine its expiration date. When urine testing is required, after midstream urine sampling is completed, the rotary reagent card 1 is driven to rotate at a specified angle so that the unused reagent strip No. N reaches the injection station, so that the reagent strip No. N is directly below the injection needle 21 to wait for injection and signal acquisition. After the injection is completed, after waiting for the reagent reaction to a preset time, the signal acquisition work is started directly. After the signal acquisition is completed, the control module further analyzes and processes the acquired data, and sends it to the host computer or cloud for further processing through the wireless communication module, and generates a urine test report and pushes it to the urine tester.

[0062] The rotary urine testing device provided by this invention has a simple structure. It only requires a drive mechanism to deliver the rotary reagent card 1 to the sample injection station, the signal acquisition station, and the sample injection mechanism for sample injection, thereby completing the test. The operation is simple and efficient, the overall device operates stably, and the time required for the entire urine test process is greatly shortened.

[0063] In one embodiment, the device further includes a housing 03, in which the rotary reagent card 1, the sample injection mechanism, the drive mechanism, and the acquisition and detection unit are all housed, which can protect the internal mechanisms. At the same time, the housing 03 can be installed inside the toilet, allowing users to use the device for urine testing as if they were using the toilet.

[0064] In one embodiment, the above-mentioned device further includes a buffer bottle 7, which is located below the rotary reagent card 1, and the opening of the buffer bottle 7 corresponds to the position of the injection needle 21. In order to avoid leakage, the injection needle 21 is strictly aligned with the position of the notch 10 on the rotating cylinder 12 and the sealing port of the buffer bottle 7, so as to ensure the effectiveness of the seal after the injection needle 21 moves down to the sealing position of the buffer bottle 7, and to ensure that the injection needle 21 can pass through the notch 10 to reach the sealing position of the buffer bottle 7.

[0065] Reference Figure 6 The present invention also provides a urine testing toilet, including a toilet body and a rotary urine testing device as described above, wherein the rotary urine testing device is installed in the toilet body.

[0066] The present invention also provides a detection method for detecting urine, comprising:

[0067] S1: Rotate the rotary reagent card 1 to rotate the test strip to the injection station;

[0068] To ensure the accuracy and precision of the test, first rotate the rotary reagent card 1 to the position of the notch 10, move the injection needle 21 downward to the buffer bottle 7, then open the injection needle 21 to remove excess air from the injection needle 21 and the tubing, so that the injection needle 21 is filled with the urine to be tested, and then move the injection needle 21 upward.

[0069] S2: Drive the injection needle 21 downward by a specified step length and insert it into the injection port 110 of the test strip to inject the urine sample in the injection needle 21 into the test strip. After the injection is completed, the injection needle 21 moves upward.

[0070] S3: After the injection is completed, the injection needle 21 moves upward and rotates the injected reagent strip 11 to the signal acquisition station via the rotary reagent card 1. The signal acquisition module 41 then acquires the signal from the injected reagent strip 11. Alternatively, after the injection is completed, the signal acquisition module 41 directly acquires the signal from the injected reagent strip 11 and sends it to the control module for further analysis and processing.
