Description

Technical Field

[0001] This application relates to the field of urine sampling technology, and in particular to a method and system for collecting midstream urine samples. Background Technology

[0002] Urine analysis is a routine part of medical visits or physical examinations. As a basic part of physical examinations, urine analysis can reflect the types and conditions of diseases of the urinary system (kidneys, ureters, bladder, and urethra, etc.).

[0003] Urine analysis requires urine sampling, and it is best to collect midstream urine. Urine can be divided into the initial, midstream, and final portions based on the order of urination. Because the initial and final portions are more easily contaminated, during routine urinalysis and urine bacteriological examinations, the first 10-30 mL of urine is usually removed, and the subsequent midstream urine is collected.

[0004] Currently, the urine sampling process mainly involves the following steps: the examinee takes a urine cup and a urine analysis tube with a barcode (hereinafter referred to as the urine tube) into the restroom, collects midstream urine into the urine cup, opens the cap of the urine tube, pours approximately 10 mL of urine from the urine cup into the urine tube, screws the cap back on, and discards the remaining urine in the urine cup. This collection process is prone to urine splashing, contaminating the examinee's hands and other parts of the body; moreover, holding the urine cup and urine tube makes it inconvenient to put on and take off clothing, making the urine sampling process cumbersome and difficult. Therefore, developing a fully automated intelligent urine sample collection system is essential. Summary of the Invention

[0005] To address or partially address the problems existing in related technologies, this application provides a method and system for collecting midstream urine samples, which can achieve fully automated collection of midstream urine samples, avoid urine contamination of the subject's body, clothing, etc. during the collection process, and has high accuracy in the amount of samples collected.

[0006] The first aspect of this application provides a method for collecting midstream urine samples, comprising: The system calls the corresponding sampling device based on the collection command issued by the user and issues a sampling instruction message to instruct the user to collect midstream urine. The first detector is used to detect the amount of midstream urine sample in the sampling device. When the amount reaches the preset value of midstream urine sample, the sampling device is driven to move to the post-processing area. The second detector is used to detect the sampling tube information in the post-processing area. When the preset conditions are met, the post-processing device is driven to perform post-processing operations, so that the collected midstream urine sample is sealed in the sampling tube. Issue an end indication message to indicate the end of midstream urine collection.

[0007] In some implementations, before calling the corresponding sampling device according to the user's collection command, the method further includes: calling the corresponding toilet according to the user's identity information or the user's selection.

[0008] In some implementations, the step of invoking the corresponding sampling device according to the user's collection command and issuing sampling instruction information to instruct the user to perform midstream urine collection includes: The system calls the corresponding sampling device to collect the first-stage urine sample according to the collection command issued by the user, and issues a first-stage urine sampling instruction to instruct the user to collect the first-stage urine sample. The first detector detects the amount of urine sample in the sampling device. When the amount reaches the preset value of urine sample in the first segment, the sampling device is driven to switch to the midstream urine sample collection mode and a midstream urine sampling instruction is issued to instruct the user to collect midstream urine.

[0009] In some implementations, the step of invoking the corresponding sampling device according to the user's collection command includes: According to the collection command issued by the user, the corresponding sampling device is invoked, so that the first sampling cup of the sampling device is connected to the front urine sample tube and the second sampling cup is connected to the sampling tube. The method involves using a first detector to detect the amount of initial urine sample in the sampling device. When the initial urine sample reaches a preset value, the sampling device is driven to switch to midstream urine sample collection mode, and a midstream urine sampling instruction is issued to instruct the user to collect midstream urine. This includes: The first detector detects the amount of urine sample collected from the first sampling cup into the urine sample tube. When the amount reaches the preset value of the urine sample, the sampling device is driven to switch to the midstream urine sample collection mode and a midstream urine sampling instruction is issued to instruct the user to collect midstream urine. The step of using a first detector to detect the amount of midstream urine sample in the sampling device, and driving the sampling device to move to the post-processing area when the amount reaches a preset value for midstream urine sample, includes: The first detector is used to detect the amount of midstream urine sample collected in the sampling tube through the second sampling cup. When the amount reaches the preset value of midstream urine sample, the sampling device is driven to move to the post-processing area.

[0010] In some implementations, the step of invoking the corresponding sampling device according to the user's collection command includes: Scan and obtain user identity information; The corresponding sampling device is invoked according to the collection command issued by the user; The second detector detects the sampling tube information in the post-processing area. When a preset condition is met, the post-processing device is driven to perform post-processing operations, sealing the collected midstream urine sample inside the sampling tube. An end indication message is issued to indicate the end of midstream urine collection, including: The second detector is used to detect whether a sampling tube exists at the sealing site in the post-processing area; if it does, the sampling tube is sealed so that the collected midstream urine sample is sealed inside the sampling tube. The sealed sampling tube is labeled according to the user's identity information; The labeled sampling tube is moved to the sample transfer site in the post-processing area, and an end indication message is issued to indicate the end of midstream urine collection.

[0011] In some implementations, the second detector is activated when it receives a detection result from the first detector that "the midstream urine sample volume has reached the preset value for midstream urine samples".

[0012] A second aspect of this application provides a midstream urine sample collection system, comprising: The pre-processing device is used to call the corresponding sampling device according to the collection command issued by the user and to issue sampling instruction information to instruct the user to collect midstream urine. A sampling device is used to detect the amount of midstream urine sample in the sampling device using a first detector, and when the amount reaches a preset value of midstream urine sample, the sampling device is driven to move to the post-processing area. The post-processing device is used to detect the sampling tube information of the post-processing area using a second detector, and when the preset conditions are met, it drives the post-processing device to perform post-processing operations so that the collected midstream urine sample is sealed in the sampling tube; it is also used to issue an end indication message to indicate that the midstream urine collection has ended.

[0013] In some embodiments, the sampling device further includes a first sampling cup, a second sampling cup, a front urine sample tube, and a sampling tube; The first sampling cup includes a first sampling part and a first feeding channel that are interconnected. The second sampling cup includes a second sampling part and a second feeding channel that are interconnected. Both the first sampling part and the second sampling part are open. The end of the first feeding channel away from the first sampling part can be connected to the front urine sample tube. The end of the second feeding channel away from the second sampling part can be connected to the sampling tube.

[0014] In some embodiments, the opening diameter of the second sampling part is larger than that of the first sampling part, the first sampling part is placed inside the second sampling part, and the outer side of the first sampling part is in close contact with the inner side of the second sampling part; the end of the first sampling part away from the first feeding channel has a closing component, and the closing component is electrically connected to the first detector; During the initial urine sample collection process, the first sampling section is set up in an open shape; When the first detector detects that the amount of urine sample in the first urine sample tube has reached a preset value, the first sampling section is changed from an open shape to a closed shape by the closing component.

[0015] A third aspect of this application provides an electronic device, comprising: Processor; and A memory that stores executable code, which, when executed by the processor, causes the processor to perform the method described above.

[0016] A fourth aspect of this application provides a computer-readable storage medium having executable code stored thereon, which, when executed by a processor of an electronic device, causes the processor to perform the method described above.

[0017] The technical solution provided in this application can include the following beneficial effects: Through the cooperation of the pre-processing device, sampling device, and post-processing device, fully automated collection of midstream urine samples from the examinee can be achieved, eliminating the need for manual operation by the examinee and ensuring that the examinee is not contaminated by urine during the midstream urine collection process. Furthermore, through the mutual cooperation of the various detectors, the midstream urine sample from the examinee can be collected more accurately, avoiding the influence of contaminants carried in the initial urine sample on the examinee's urine test results. The separate sampling container allows for the separate collection of initial and midstream urine samples, further preventing contamination of the midstream urine sample by the initial urine sample. Moreover, its simplified structure maximizes space utilization and has a wide range of applications.

[0025] Urine analysis is very important, but current methods of collecting urine samples are inconvenient and have drawbacks such as odor emission and easy hand contamination.

[0026] To address the aforementioned issues, this application provides a method and system for collecting midstream urine samples, which enables fully automated collection of midstream urine samples, avoids contamination of the subject's body and clothing during the collection process, and achieves high accuracy in the collected sample volume.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] It should be noted that the midstream urine sample collection system described in this application can exist independently of the defecation device, meaning it can be added to the defecation device later as needed; alternatively, it can be manufactured as an integrated system with the defecation device and used as a complete set of equipment. The following detailed description uses the complete set of equipment integrated into the toilet as an example.

[0029] Figure 1 This is a schematic diagram of the overall structure of the midstream urine sample collection system shown in Embodiment 1 of this application. Figure 2 This is a schematic diagram showing the location of the internal structure of the midstream urine sample collection system as illustrated in Embodiment 1 of this application.

[0030] See Figure 1 and Figure 2 The system can be installed on a wall or mounted on a rack. This midstream urine sample collection system includes a defecation device 1, a pre-processing unit 2, a sampling unit 3, and a post-processing unit 4.

[0031] The defecation device 1 includes a toilet and a flushing mechanism. The toilet is a complete set of mechanisms including a toilet bowl 11, a first washer 12, a second washer 13, a cover, and a handrail (not shown in the figure). Users can call the corresponding toilet according to their identity information or user selection, so as to adapt to users of different ages, genders, and needs.

[0032] The commode 11 is located on the ground and is open-topped, serving as the defecation area. The interior of the commode 11 connects to an external sewage pipe, allowing urine and other waste to be discharged into the pipe. Above the commode 11, a first washer 12, a second washer 13, a cover, and a handle are sequentially connected and rotated. The second washer 13 is taller than the first washer 12. Both the first washer 12 and the second washer 13 are annular structures with an opening in the center. They are made of materials such as rubber or silicone, with smooth upper surfaces to facilitate direct contact with human skin.

[0033] When the user of the midstream urine sample collection system is male, the toilet can be a single commode 11; when the user is a young female or a woman shorter than 1.0m, the toilet can be a combination of commode 11 and seat 12 (sitting height approximately 0.25m); when the user is an adult female or a woman taller than 1.0m, the toilet can be a combination of commode 11, seat 12, and seat 2 13 (sitting height approximately 0.4m); when the user is a person with mobility impairment or disability, other assistive devices such as handrails can be used in addition to the above to meet the midstream urine sample collection needs of different groups. The toilet selection can also be made by the user according to their individual needs.

[0034] The pre-processing device 2 includes a scanner 21, a speaker 22, and a display 23. The display 23 can be positioned to the side or above the defecation device 1, and includes a screen for demonstrating how to use the midstream urine sample collection system, as well as buttons for users to select the appropriate processing method based on their individual needs. Users can select the corresponding toilet based on their personal information (including gender, age, and other details) using the buttons. The screen can also display barcodes, QR codes, or other similar patterns. Users can scan these patterns using a mobile device such as a smartphone and fill in or confirm their personal information, enabling the midstream urine sample collection system to obtain the user's identity information and automatically select the appropriate toilet based on that information.

[0035] The scanner 21 can be integrated with the display 23 or set up separately. The scanner 21 can be a QR code scanner, barcode scanner, etc., to obtain the user's identity information by scanning the user's examination form or the subject's examination code displayed on the user's mobile device, such as a mobile phone. Alternatively, it can be an ID card / medical insurance card scanner to identify and record the user's identity information by scanning the user's ID card / medical insurance card.

[0036] The speaker 22 can be integrated with the display 23 or set up separately. Once the user's identity information is obtained, the subject's information is confirmed, which is considered as the user issuing a collection command. The system can then call the corresponding sampling device 3 based on the user's collection command. Alternatively, the user can issue a collection command via a button on the display 23, thereby calling the corresponding sampling device 3. Alternatively, the user can issue a collection command via a mobile device, thereby calling the corresponding sampling device 3. Simultaneously, the speaker 22 emits sampling instruction information to instruct the user to perform midstream urine collection, allowing the user to move to a suitable position and prepare for midstream urine collection.

[0037] In addition, the defecation device 1 or the pre-treatment device 2 may also include a detector, for example, installed around the urinal 11 or around the display 23, to detect the distance between the user and the urinal 11 to determine whether the user is ready to defecate. Before the user is ready, a prompt message can be issued through the speaker 22 to guide the user to move to a suitable position; when the user is detected to have moved to a suitable position, a sampling instruction message is issued.

[0038] The sampling device 3 and the post-processing device 4 are located on one side of the toilet 11, and the specific components of the sampling device 3 and the post-processing device 4 can be covered by a casing or cover.

[0039] See Figure 2The sampling device 3 includes a collection mechanism. The collection mechanism includes a first telescopic rod 31, a first gripper 32, a sampling hopper 5, and a first detector 33. The sampling hopper 5 is gripped and fixed by the first gripper 32, which is fixed to one end of the first telescopic rod 31 and can move horizontally under the automatic extension and retraction of the first telescopic rod 31. The extension and retraction of the first telescopic rod 31 can be controlled by, for example, a cylinder or a lead screw motor; this application does not impose any limitations on this.

[0040] The sampling area 71 is directly above the toilet bowl 11, and the area away from the toilet bowl 11 and the user's defecation area is the post-processing area, which is the area covered by the casing or cover. When the sampling device 3 is not activated, the collection mechanism is located in the post-processing area; after the sampling device 3 is activated, the first telescopic rod 31 can drive the sampling bucket 5 to move to the sampling area 71, and after the midstream urine sampling is completed, it drives the sampling bucket 5 to move to the discharge point 72 in the post-processing area.

[0041] The sampling hopper 5 has an inlet at the top and an outlet at the bottom, and its overall shape is funnel-shaped, meaning the upper opening is larger than the lower opening, facilitating the collection of urine. During sampling, the outlet is closed; during drainage, the outlet is open. The outlet can be sealed using components such as valves, plugs, or caps; this embodiment does not limit this. The operation of changing the outlet from closed to open and vice versa can be achieved by corresponding components, such as opening and closing a valve, which can be driven by a motor to rotate or push / pull.

[0042] The first detector 33 can be installed on the first telescopic rod 31 to detect the liquid volume in the sampling hopper 5, for example, a visual sensor can be used. When the volume of midstream urine sample in the sampling hopper reaches the preset value of midstream urine sample, the first telescopic rod 31 drives the sampling hopper 5 to move from the sampling area 71 to the discharge point 72 in the post-processing area. The preset value of midstream urine sample can be set to 10 mL.

[0043] Figure 3 This is a cross-sectional view of the midstream urine sample collection system shown in Embodiment 1 of this application.

[0044] Combination Figure 2 and Figure 3 As shown, the post-processing device 4 includes a feeding mechanism and a sealing mechanism. The feeding mechanism includes a second telescopic rod 41, a second gripper 42, and a second detector 43. The second telescopic rod 41, the second gripper 42, and the second detector 43 are all located in the post-processing area. The second gripper 42 is connected to the movable end of the second telescopic rod 41 and is used to grip and fix the sampling tube 6, connecting or moving the opening of the sampling tube 6 below the outlet of the sampling hopper 5. The extension and retraction of the second telescopic rod 41 can be controlled by, for example, a cylinder or a lead screw motor; this application does not impose any limitations on this.

[0045] The second detector is activated when it receives the detection result from the first detector that "the midstream urine sample volume has reached the preset value for midstream urine samples".

[0046] When the second detector 43 detects the presence of the sampling tube 6 at the discharge point 72 in the post-processing area, the system drives the outlet of the sampling hopper 5 from a closed state to an open state, allowing the midstream urine sample in the sampling hopper 5 to be discharged into the sampling tube 6. After discharge, the second telescopic rod 41 drives the second gripper 42 to move the sampling tube 6 to the sealing point 73 in the post-processing area. The sampling tube 6 can be placed into the second gripper 42 by the user when issuing a collection command, and then moved to the discharge point 72 by the second gripper 42; alternatively, a tube 44 can be set up in the system to store the sampling tube 6, and a robotic arm can be set up to retrieve the sampling tube 6. After the user issues a collection command, the robotic arm retrieves the sampling tube 6 from the lower opening of the tube 44, transfers it into the second gripper 42 for fixation, and then the second telescopic rod 41 drives the second gripper 42 to move the sampling tube 6 to the discharge point 72.

[0047] In addition, the post-processing device 4 also includes a sealing mechanism located in the post-processing area. The sealing mechanism includes a tube cap 45, a robotic arm, and a suction cup 46. The tube cap 45 is located above the second gripper 42, and has an opening at the bottom to allow a single sampling tube cap to pass through. The movable end of the robotic arm is connected to the suction cup 46. When the second detector 43 detects the presence of a sampling tube 6 at the sealing site 73, the system drives the suction cup 46 to pick up the sampling tube cap and moves it to the opening of the sampling tube 6 under the action of the robotic arm, then tightens it at the opening of the sampling tube 6, thus sealing the collected midstream urine sample inside the sampling tube 6.

[0048] Furthermore, the post-processing device 4 may also include a marking mechanism. The marking mechanism is located in the post-processing area and imprints the acquired user identification information label onto the sampling tube 6 or the sampling tube cap during or after sealing. The marking mechanism described in this application may be, for example, a label printer, an inkjet printer, etc., and this application does not limit its application to this.

[0049] The end of the second telescopic rod 41 furthest from the second gripper 42 is connected to a rotating shaft. Driven by a motor or other driving source, the second telescopic rod 41 rotates relative to the rotating shaft, centering on it, to move the second gripper 42 and the sampling tube 6 to the sample transfer point 74. A stop signal is then emitted by the speaker 22 to indicate the end of mid-stream urine collection. Figure 1As shown, the sample transfer point 74 can be an open window for the user to place the sampling tube 6 in the second gripper 42, and for the user to remove the collected midstream urine sample sampling tube 6. The sample transfer point 74 can also be the inlet of a delivery pipeline connecting to a urine testing laboratory, through which the collected midstream urine sample sampling tube 6 is transported to the laboratory for testing, eliminating the need for staff or users to deliver the sample to the laboratory, thus saving manpower.

[0050] Furthermore, the post-processing device 4 may also include a rinsing mechanism 47. The rinsing mechanism 47 is located above the feeding point 72, and below the feeding point 72 is a water collection tank 48, which is connected to a sewage pipe to discharge wastewater. When the mid-section urine sample in the sampling hopper 5 is transferred to the sampling tube 6 and moved to the sample transfer point 74, the rinsing mechanism 47 can spray water to rinse the sampling hopper 5 and the first gripper 32, and then blow air to dry the sampling hopper 5 and the first gripper 32. The rinsing water flows into the water collection tank 48 below. This avoids urine residue damaging the equipment and contaminating samples collected by other users; it also reduces the use of disposable sampling consumables such as urine cups.

[0051] Furthermore, the post-processing device 4 may also include a cleaning mechanism. The cleaning mechanism is located in the sealing area. After sealing and before marking, the sampling tube 6 can be rinsed with water and dried by air to prevent urine residue from remaining on the surface of the sampling tube 6 or the second gripper 42 during the feeding process, thus keeping the equipment clean and preventing stains on the surface of the sampling tube 6 from contaminating the user's hands.

[0052] Corresponding to the aforementioned system embodiments, this application also provides a method for collecting midstream urine samples. Figure 4 This is a schematic flowchart of the midstream urine sample collection method shown in Embodiment 1 of this application.

[0053] See Figure 4 The method for collecting midstream urine samples includes the following steps: S11. The corresponding sampling device is invoked according to the collection command issued by the user, and a sampling instruction message is issued to instruct the user to perform midstream urine collection.

[0054] Before invoking the corresponding sampling device 3 according to the user's collection command, the system may also include selecting the appropriate toilet based on the user's identity information or identity. That is, the user can select a toilet suitable for their personal identity through the corresponding button on the display 23, specifically by selecting the appropriate toilet based on their gender, age, and other special needs, making it convenient for users of different genders and identities to use the device.

[0055] Subsequently, the user can be scanned using the pattern shown on scanner 21 or display 23 to obtain user identity information, thereby confirming that the user is the subject who needs to use sampling device 3. This automatically wakes up and triggers the midstream urine sample collection system to perform midstream urine sample collection. If there is no scanning step, it can be determined that the user has a normal bowel movement need, and there is no need to collect a urine sample; therefore, the sample collection system is not triggered. The user's identity information may include the user's physical condition, gender, age, and examination items.

[0056] In some implementations, user identity information can be scanned and obtained, and the corresponding sampling device 3 can be invoked according to the user's collection command. Invoking the corresponding sampling device 3 can be based on the user's selection command on the display 23 or personal client, such as whether a sampling tube 6 is needed. For example, if the user selects to use a sampling tube 6, a robotic arm will retrieve the sampling tube 6 from the tube 44; if the user selects not to use a sampling tube 6, the user's own sampling tube 6 will be retrieved and moved to the appropriate position on the sampling device 3. This can adapt to different scenarios and the needs of different users.

[0057] The sampling instruction information can be presented to the subject via voice from speaker 22, screen display of monitor 23, or information received by mobile devices such as mobile phones, to prompt the subject to move to the side of the urinal 11 to prepare for urination, so that the urine excreted by the subject can be collected more accurately by the sampling device 3.

[0058] Before issuing the sampling instruction, the process may also include: detecting whether the subject is located in the designated area; and issuing the sampling instruction when the subject's location meets the requirements, to instruct the subject to collect midstream urine. The designated area is the area around the commode; that is, when the detector detects that the subject is in the designated area, the sampling instruction is issued so that the subject can empty urine into the sampling commode.

[0059] Since the urine analysis requires midstream urine, the examinee can judge whether the first part of the urine has been emptied based on the urination time, and then adjust their posture to allow the urine to flow into the sampling container 5 for midstream urine collection.

[0060] Furthermore, the system can also set a preset time / value for the initial urine sample based on historical urination time or the volume / weight of urine collected in the urination area. When the urination time reaches the preset time for the initial urine sample or the volume / weight of urine collected in the urination area reaches the preset value for the initial urine sample, it is determined that the subject has finished urinating the initial urine, and a sampling instruction is issued to instruct the subject to collect the midstream urine, thereby reducing errors caused by the subject's own judgment. For example, the preset time for the initial urine sample can be set to 3-5 seconds. After the preset time is reached, the subject is prompted to adjust their posture so that the urine flows into the sampling container 5. At the same time, the sampling container 5 of the sampling device 3 moves from the post-processing area to the sampling area 71 to collect the midstream urine.

[0061] S12. The first detector is used to detect the amount of midstream urine sample in the sampling device. When the amount reaches the preset value of midstream urine sample, the sampling device is driven to move to the post-processing area.

[0062] When the amount of midstream urine sample in sampling hopper 5 reaches the preset value, such as when the volume of midstream urine sample in sampling hopper 5 reaches the preset volume of midstream urine, sampling hopper 5 will automatically move away from sampling area 71. This enables automatic collection of midstream urine samples without the need for manual removal of sampling hopper 5, avoiding the problem of urine contaminating hands or other parts, and achieving pollution-free automatic collection. Furthermore, through automated control, an appropriate amount of midstream urine sample can be obtained more accurately, and there is no residual first-stream urine in sampling hopper 5, minimizing sample interference.

[0063] The preset value for the midstream urine sample in this embodiment can be volume, weight, etc., or it can be marked with graduation lines on the side wall of the sampling chamber 5. When the graduation line is reached, it is determined that the preset value for the midstream urine sample has been reached. This application does not limit this.

[0064] S13. Use the second detector to detect the sampling tube information in the post-processing area. When the preset conditions are met, drive the post-processing device to perform post-processing operations so that the collected midstream urine sample is sealed in the sampling tube.

[0065] In some implementations, the second detector 43 can be used to detect whether the sampling tube 6 exists at the sealing point 73 in the post-processing area; if it exists, the sampling tube 6 is sealed so that the collected midstream urine sample is sealed inside the sampling tube 6; the sealed sampling tube 6 is labeled according to the user's identity information; the labeled sampling tube 6 is moved to the sample transfer point 74 in the post-processing area and an end indication message is issued to indicate that the midstream urine collection is completed.

[0066] Furthermore, the second detector 43 can be used to detect whether there is a sampling tube 6 at the discharge point 72 in the post-processing area and whether there is a sampling hopper 5 above the discharge point 72. When the positional relationship between the sampling tube 6 and the sampling hopper 5 meets the preset conditions, the system drives the outlet at the lower end of the sampling hopper 5 from a closed state to an open state, so that the midstream urine sample in the sampling hopper 5 is discharged into the sampling tube 6, and then the sampling tube 6 is transferred to the sealing point 73. When the sampling tube 6 is present at the sealing point 73, the system drives the robotic arm to move and pick up the sampling tube cap through the suction cup 46, then moves it to the opening of the sampling tube 6 and tightens it at the opening of the sampling tube 6, so that the collected midstream urine sample is sealed in the sampling tube 6. After sealing, the user identification label obtained in step S11 is imprinted on the surface of the sampling tube 6 or the cap of the sampling tube. Then, the sampling tube 6 is moved to the sample transfer point 74 in the post-processing area for the user to take or to be transported to the laboratory for testing via the delivery pipeline.

[0067] In addition, after sealing and before marking, the system can also rinse the sampling tube 6 with water and dry it with air to ensure the cleanliness of the sampling tube 6.

[0068] It should be noted that in this embodiment, the second detector 43 is activated when it receives the detection result of the first detector 33 that "the amount of midstream urine sample has reached the preset value of midstream urine sample", so as to ensure that the processing steps such as feeding, sealing, marking, and cleaning are carried out continuously after the midstream urine sample collection step, and to avoid post-processing operations on the empty sampling tube 6.

[0069] Furthermore, after the material is fed and the sampling tube 6 moves to the sealing point 73 or the sample transfer point 74, the system can also drive the rinsing mechanism 47 to spray and rinse the sampling bucket 5 and dry it to avoid urine residue damaging the device and causing cross-interference between user samples.

[0070] S14. Issue an end indication message to indicate the end of midstream urine collection.

[0071] After the sampling tube 6 and the midstream urine sample reach the sample transfer point 74, the speaker 22 will issue an end indication message that the midstream urine sample collection is complete. The user can choose to transfer the sample by taking the sample himself or by transporting it to the laboratory through the delivery channel according to the collection command in step S11.

[0072] Figure 5 This is a schematic diagram of the sampling bucket in the midstream urine sample collection system shown in Embodiment 2 of this application.

[0073] See Figure 5The sampling container 5 consists of an upper part 51 and a lower part 52 connected by snap-fit ​​or screw-fit. The upper end of the upper part 51 is open to collect urine; the lower end is closed and has a drain hole 511. The upper end of the lower part 52 is open and is connected to the outer wall of the lower end of the upper part 51 by snap-fit ​​or screw-fit. The lower end of the upper part 51 and the upper end of the lower part 52 are connected and communicate with each other. A float 53 is located inside the lower part 52. The volume of the float 53 is larger than the diameter of the drain hole 511 and its density is less than that of urine. The float 53 is made of lightweight plastic, and its outer contour is consistent with the inner contour of the lower end of the upper part 51. An outlet is provided on the lower side of the upper part 51, and a drain outlet is provided on the lower end face of the lower part 52. During the sampling process, both the outlet and the drain are closed. Urine flows through the upper part 51 and then through the leak 511 into the lower part 52. As the amount of urine increases, the float 53 rises and blocks the leak 511. Subsequently, the urine is collected in the upper part 51. The upper part 51 and the lower part 52 are detachably connected for easy cleaning and placement of the float 53 in the lower part 52.

[0074] Therefore, when applied to midstream urine sample collection, the lower half 52 of the sampling container 5 can be used to collect the first part of the urine, and the upper half 51 can be used to collect the user's midstream urine. This eliminates the need for the user to adjust their urination posture to collect the midstream urine sample, and also reduces the waste of midstream urine when the sampling container 5 is moved to the sampling area 71 after the first part of the urine sample is collected, thus ensuring the amount of urine collected.

[0075] After the midstream urine sample collection is completed, the sampling hopper 5 moves above the discharge point 72, and the sampling tube 6 is located below and connected to the outlet of the upper half 51. The system drives the outlet to change from a closed state to an open state, allowing the midstream urine sample to flow into the sampling tube 6. After the midstream urine sample collection is completed, the system drives the drain to change from a closed state to an open state, allowing the initial urine sample to be discharged. Simultaneously, the sampling hopper 5 can be sprayed and rinsed and dried by the rinsing mechanism 47. The sealing and state change of the outlet and drain are the same as those of the outlet of the sampling hopper 5 described in Embodiment 1, and will not be repeated here.

[0076] Moreover, when using this sampling bucket 5 to collect midstream urine samples, there is no need to detect the amount of the initial urine sample collected; the midstream urine sample is automatically collected after the initial urine sample collection is completed.

[0077] Figure 6 This is a schematic diagram showing the connection position of the sampling bucket and sampling tube in the midstream urine sample collection system as illustrated in Embodiment 3 of this application. Figure 7 This is a schematic diagram showing the state of the sampling bucket in the midstream urine sample collection system as illustrated in Embodiment 3 of this application. Figure 8This is a schematic diagram of the sampling bucket in the midstream urine sample collection system shown in Embodiment 3 of this application, representing state two.

[0078] See Figure 6-8 The sampling hopper 5 includes a first sampling cup 54 and a second sampling cup 55. The first sampling cup 54 includes a first sampling part 541 and a first feeding channel 542 that are connected to each other, and the second sampling cup 55 includes a second sampling part 551 and a second feeding channel 552 that are connected to each other. Both the first sampling part 541 and the second sampling part 551 are open, and the opening diameter of the first sampling part 541 is smaller than that of the second sampling part 551. The first sampling part 541 is placed inside the second sampling part 551 and the outer side of the first sampling part 541 is in close contact with the inner side of the second sampling part 551. The upper end face of the first sampling part 541 is higher than the upper end face of the second sampling part 551. There is a curved surface at the upper end face of the first sampling part 541. When the first sampling part 541 is placed inside the second sampling part 551, the curved surface of the first sampling part 541 is placed at the upper end of the second sampling part 551, so that the upper end of the second sampling part 551 is sealed.

[0079] A closing component 56 is also provided at the upper end face of the first sampling section 541. This closing component 56 can be a pull strip with elastic deformation properties. Both ends of the pull strip are connected to a telescopic rod, which is electrically connected to the first detector 33. The opening and closing states of the first sampling section 541 can be switched through the telescopic rod and the closing component 56. The extension and retraction of the telescopic rod can be controlled by, for example, a cylinder or a lead screw motor; this application does not impose any limitations on this.

[0080] The end of the first feeding channel 542 furthest from the first sampling section 541 can be connected to the front urine sample tube 61, and the end of the second feeding channel 552 furthest from the second sampling tube 6 can be located above the sampling tube 6 and connected to the sampling tube 6. An opening can be provided on the side of the second feeding channel 552 to allow one part of the first feeding channel 542 to be located inside the second feeding channel 552 and the other part to be located outside the second feeding channel 552, so that the connection between the first feeding channel 542 and the front urine sample tube 61 is independent of the connection between the second feeding channel 552 and the sampling tube 6. The first sampling cup 54 can collect the initial urine sample into the initial urine sample tube 61. When the first detector 33 detects that the initial urine sample collection volume in the initial urine sample tube 61 has reached the preset value of the initial urine sample, it drives the first sampling part 541 to change from an open state to a closed state, so that the second sampling part 551 can receive the midstream urine in an open state. The second sampling cup 55 can collect the midstream urine sample into the sampling tube 6. When the first detector 33 detects that the midstream urine sample collection volume in the sampling tube 6 has reached the preset value of the midstream urine sample, it drives the sampling cup 5 to move from the sampling area 71 to the post-processing area to realize the collection of the midstream urine sample.

[0081] The first feeding channel 542 and the second feeding channel 552 can be corrugated pipes, which can automatically extend and retract during the movement of the sampling hopper 5 between the sampling area 71 and the post-processing area to ensure the smooth operation of the sampling device 3. A drain port can also be provided at the bottom of the front urine sample tube 61. After the mid-stage urine sample collection is completed, the urine in the front urine sample tube 61 can be drained through the drain port. Afterwards, the sampling hopper 5 and the front urine sample tube 61 can be sprayed, rinsed, and dried by the rinsing mechanism 47 to ensure the cleanliness of the sampling device 3.

[0082] Correspondingly, the midstream urine collection method involved in Example 3 may include: S21. Select the corresponding toilet based on the user's identity information or the user's identity.

[0083] S22. Based on the collection command issued by the user, the corresponding sampling device is invoked to collect the first-stage urine, and a first-stage urine sampling instruction is issued to instruct the user to collect the first-stage urine.

[0084] When the sampling device 3 used is the sampling device 3 shown in Embodiment 3, the first sampling cup 54 in the sampling device 3 is connected to the front urine sample tube 61, and the second sampling cup 55 is connected to the sampling tube 6.

[0085] S23. The first detector is used to detect the amount of urine sample in the sampling device. When the amount reaches the preset value of urine sample in the first segment, the sampling device is driven to switch to the mid-segment urine sample collection mode and a mid-segment urine sampling instruction is issued to instruct the user to collect mid-segment urine.

[0086] When the sampling device 3 is the sampling device 3 shown in Embodiment 3, the first detector 33 is used to detect the amount of pre-stream urine sample collected by the first sampling cup 54 into the pre-stream urine sample tube 61. When it reaches the preset value of pre-stream urine sample, the sampling device 3 is driven to switch to the mid-stream urine sample collection mode and a mid-stream urine sampling instruction message is issued to instruct the user to collect mid-stream urine. S24. The first detector is used to detect the amount of midstream urine sample collected in the sampling tube through the second sampling cup. When the amount reaches the preset value of midstream urine sample, the sampling device is driven to move to the post-processing area.

[0087] S25. Use the second detector to detect the sampling tube information in the post-processing area. When the preset conditions are met, drive the post-processing device to perform post-processing operations so that the collected midstream urine sample is sealed in the sampling tube.

[0088] S26. Issue an end indication message to indicate the end of midstream urine collection.

[0089] Except for the urine sample collection process, which differs from the method described in Example 1, all other steps can be described in accordance with the method described in Example 1, and will not be repeated here.
