Description

Technical Field

[0001] This invention relates to the field of medical devices, specifically to an automatic excrement sampling device for the digestive system. Background Technology

[0002] In medical settings, especially in gastroenterology clinics, obtaining fecal samples from patients is a common diagnostic procedure. These samples are of significant value in analyzing a patient's gut health, digestive system function, and potential diseases. However, traditional fecal sampling methods often rely on visual observation and manual operation by patients or medical staff. This not only increases the difficulty and error of sampling but also carries the risk of cross-infection, impacting the efficiency of medical services and the patient experience.

[0003] Currently, some excrement sampling devices exist on the market, but most still employ relatively traditional methods. For example, some devices require patients to collect their own excrement samples and place them in a container, which are then transported to a laboratory for testing by medical staff. This method is not only cumbersome but also prone to contamination or errors during sampling. Furthermore, traditional sampling methods require manual operation by patients or medical staff, increasing workload and potentially leading to inaccurate sampling due to improper handling. During sampling, patients or medical staff may directly contact the excrement, increasing the risk of cross-infection. Therefore, this proposal suggests an automated excrement sampling device for gastroenterology. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides an automatic excrement sampling device for gastroenterology, which allows for convenient excrement sampling while reducing the risk of cross-infection.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: An automatic excrement sampling device for gastroenterology includes a toilet seat, an infrared sensor fixedly connected to the inner side wall of the toilet seat, the infrared sensor being used to detect the temperature distribution of the excrement, the infrared sensor signal being connected to a controller, and several lifting components being provided at the bottom of the toilet seat, each of the lifting components being signal connected to the controller. When the infrared sensor detects the excrement signal, the infrared sensor transmits the acquired excrement information to the controller, and the controller controls the operation of the lifting components based on the excrement information. Each lifting component is fixedly connected to a collector.

[0006] The collector includes a collection chamber with an opening at the top. A sealing plate is slidably connected to one side of the opening. A first transmission assembly is provided between the sealing plate and a lifting component. The first transmission assembly is used to move the sealing plate to open the opening when the lifting component is raised. A bracket is fixedly connected inside the collection chamber. A collection bag is fitted on the bracket. A movable component is provided on one side of the bracket. The movable component is used to tighten the collection bag. A baffle is provided below the collection bag. The baffle is vertically slidably connected to the inner wall of the collection chamber. A second transmission assembly is provided between the movable component and the baffle. The second transmission assembly is used to tighten the collection bag when the baffle moves downward.

[0007] The technical principle of the above solution is as follows: When a patient needs to obtain a fecal sample during a gastroenterology examination, the patient can sit on the toilet seat to defecate, allowing the feces to fall into the toilet seat. At this time, an infrared sensor acquires the temperature information inside the toilet seat and transmits the temperature information to the controller. The controller determines the position of the feces based on the temperature information and controls the corresponding lifting component to rise. When the lifting component rises, the first transmission component moves the sealing plate to open the opening. At this time, the feces can accurately fall into the opening and enter the collection bag. When the weight inside the collection bag increases, the bottom of the collection bag squeezes the baffle, causing the baffle to move vertically downward. The baffle drives the moving component to move through the second transmission component, causing the moving component to tighten the collection bag, completing the packaging of the feces.

[0008] The above approach has the following beneficial effects:

[0009] 1. This solution uses infrared sensors to monitor the temperature distribution inside the toilet bowl in real time, enabling precise determination of the location of excrement. This intelligent design avoids errors from manual judgment and ensures accurate sampling. The lifting component automatically rises according to the controller's instructions, generating a thrust on the excrement for easy collection. The sealing plate is automatically opened via the first transmission component, allowing the excrement to fall accurately into the collection bag. This process requires no manual intervention, improving operational convenience.

[0010] 2. This solution utilizes infrared sensors to detect the temperature distribution of excrement, enabling precise identification of its location. This positioning method is more accurate than traditional visual observation, ensuring sampling precision. A controller raises the lifting mechanism, aligning the collection bag with the excrement, further improving sampling accuracy.

[0011] 3. This solution utilizes an automated sampling device to prevent patients or medical staff from directly contacting excrement, reducing the risk of cross-infection and improving hygiene. After collecting excrement, the collection bag automatically tightens and seals via a moving mechanism, effectively preventing leakage and odor emission, ensuring a clean and comfortable environment, and also reducing the risk of cross-infection.

[0012] 4. With this solution, patients only need to sit on the commode to defecate; no additional operations are required to complete the sampling process. This design greatly simplifies the sampling process and improves the patient's experience. The various components of the device are rationally designed, easy to disassemble and clean, and facilitate routine maintenance by medical staff.

[0013] 5. This solution utilizes an automated sampling device that can complete the sampling process in a short time, improving work efficiency. This device is not only suitable for gastroenterology examinations but can also be applied to other medical examinations requiring excrement samples, demonstrating broad practical value.

[0014] 6. With this solution, after the collection bag is tightened and sealed, it can be easily processed later, such as being sent to the laboratory for testing, thus improving the convenience of processing.

[0015] Furthermore, the first transmission component includes a rack and a gear. The collection compartment has a slot on the side near the inner wall of the toilet bowl. The rack is located in the slot and is fixedly connected to the inner wall of the toilet bowl. The gear is rotatably connected to the collection compartment and meshes with the rack. A connecting rod is rotatably connected to one side of the gear, and the end of the connecting rod away from the gear is hinged to one side of the sealing plate.

[0016] Beneficial effects: The compact meshing structure of the rack and pinion effectively converts the vertical movement of the lifting component (such as the collection bin) into the rotational motion of the gear. The ingenious design of the connecting rod further converts the gear's rotation into the opening and closing motion of the sealing plate, resulting in a highly efficient and smooth transmission process. Without manual intervention, when the lifting component rises, the rack moves and meshes with the gear, thereby driving the connecting rod and sealing plate to open automatically. This automated operation reduces the tediousness and errors of manual operation, improving sampling efficiency and accuracy.

[0017] Furthermore, the second transmission assembly includes a first rod, a second rod, a first slider, and a second slider. The first rod and the first slider are located on one side of the baffle, and the second rod and the second slider are located on the other side of the baffle. The baffle is wedge-shaped with an inclined upper surface. The two sides of the first rod are rotatably connected to the baffle and the first slider, respectively. The two sides of the second rod are rotatably connected to the baffle and the second slider, respectively. The first slider and the second slider are both laterally slidably connected to the bracket. The moving part includes a first locking block and a second locking block. The first locking block is fixedly connected to the side of the first slider near the second slider, and the second locking block is fixedly connected to the side of the second slider near the first slider. A heating element is embedded in the second locking block.

[0018] Beneficial Effects: A simple yet effective transmission mechanism is constructed by utilizing the rotational connection between the first and second rods and the baffle, and the lateral sliding connection between the first and second sliders on the support. The design of the first and second locking blocks cleverly achieves the tightening and sealing functions of the collection bag, resulting in a compact and efficient structure. As excrement falls into the collection bag and gradually increases in weight, the baffle automatically moves downward. This movement is transmitted to the first and second sliders via the first and second rods, thereby driving the first and second locking blocks to converge towards the center. This series of actions requires no manual intervention, achieving automated operation and improving sampling efficiency and accuracy. The heating element is embedded in the first locking block. When the first and second locking blocks converge and clamp the collection bag, the heating element rapidly heats and melts the material of the collection bag, achieving a reliable sealing effect. This sealing method is not only strong but also aesthetically pleasing, effectively preventing sample leakage or contamination. Since the entire transmission and sealing process is completed automatically, the direct contact between medical personnel and excrement is reduced. This not only protects the safety of medical personnel but also reduces the risk of cross-infection.

[0019] After sealing, the inclined baffle provides a gravitational component to the collection bag, causing it to slide down along the baffle's inclination. Due to the inclination of the baffle's upper surface, the collection bag, under its own weight, experiences a downward sliding tendency as the component of gravity along the baffle's incline overcomes the tension of the top support and the friction of the bottom baffle. Simultaneously, as the baffle moves downward, the second transmission component tightens and seals the collection bag. At this point, the connection between the collection bag and the support is released or loosened, and under the influence of gravity, the collection bag smoothly slides down the inclined baffle to the guide plate, achieving automatic unloading. This design utilizes the component of gravity and the inclined baffle structure to ensure that the collection bag reliably slides down after sealing, avoiding failure to fall due to weight instability. This improves the automation and reliability of the sampling device and ensures the continuity of the sampling process.

[0020] Furthermore, a water tank is fixedly connected to one side of the toilet bowl, and an infusion tube is connected to the water tank. The infusion tube is connected to the toilet bowl, and a water pump is connected to the infusion tube. The water pump is connected to the controller via a signal, and a water outlet is connected to one side of the toilet bowl.

[0021] Beneficial Effects: This design enables the toilet bowl to automatically flush after sampling, maintaining cleanliness and hygiene. The water pump's control allows for precise adjustment of the flushing water intensity and duration, ensuring effective flushing. The water pump is connected to the controller for automatic flushing. Once sampling is complete, the controller automatically sends a signal to the water pump to initiate the flushing process, requiring no manual intervention. Precise control of the pump's operating time and water flow intensity effectively reduces water waste. This not only aligns with environmental protection principles but also lowers operating costs.

[0022] Furthermore, an opening is provided on one side of the bottom of the collection chamber, and a door is rotatably connected to one side of the opening. An inclined guide plate is fixedly connected to the bottom of the collection chamber, and the height of the side of the guide plate away from the door is higher than the side of the guide plate close to the door.

[0023] Beneficial effects: The use of guide plates and openings makes it easy to direct the collection bag outwards, thus improving the output efficiency.

[0024] Furthermore, a camera is embedded on one side of the toilet seat. The camera is connected to the controller, which is connected to a terminal device. The camera is used to acquire image information of the excrement and the controller transmits the image information to the terminal device.

[0025] Beneficial Effects: The camera can acquire real-time images of excrement and transmit them to a terminal device. Doctors or medical professionals can remotely view the state of the excrement through the terminal device, thereby making a preliminary diagnosis or assessment. This real-time monitoring function helps to promptly detect potential digestive system problems or diseases in patients, providing timely treatment suggestions. Through the excrement images acquired by the camera, doctors can more intuitively observe the color, shape, texture, and other characteristics of the excrement. These characteristics are of significant reference value for diagnosing certain digestive system diseases, helping to improve diagnostic accuracy. Traditional excrement sampling methods often require patients to collect samples themselves and send them to the hospital for testing, which may lead to inaccurate sampling or sample contamination. The automatic acquisition of excrement images by camera avoids these problems and reduces errors from manual sampling.

[0026] Furthermore, several springs are fixedly connected to the bottom of the baffle, and the bottom ends of the springs are all fixedly connected to the bracket.

[0027] Beneficial effects: The spring design acts as a buffer and shock absorber. When excrement falls into the collection chamber, the spring absorbs the impact force. Simultaneously, when the collection bag exits, the pressure on the spring disappears, and the baffle automatically returns to its original position, facilitating the next collection cycle.

[0028] Furthermore, the lifting component includes an electromagnet and an iron block. The electromagnet is fixedly connected to the bottom wall inside the toilet bowl, and the iron block is embedded in the bottom wall of the collection compartment.

[0029] Beneficial effects: The combination of electromagnets and iron blocks enables efficient lifting of the collection bin. The lifting of the electromagnets and iron blocks can be automated via a controller, improving ease of use.

[0030] Furthermore, a battery pack and a charging interface are fixedly connected to one side of the bottom of the toilet seat. The battery pack is used to provide power support for the entire device, and the charging interface is used to connect an external power source to charge the battery pack. The power management module is also used for power monitoring. When the power is lower than the preset value, the controller will activate a low power alarm and transmit the alarm information to the terminal device.

[0031] Beneficial effects: The battery pack provides power to the entire device, ensuring normal operation even during power outages. The charging port allows for easy connection to an external power source, guaranteeing continuous device use. The power management module's power monitoring function monitors the battery pack's level in real time and triggers a low-battery alarm when the battery level drops below a preset value, reminding the user to charge the battery promptly and preventing the device from shutting down due to depletion of power.

[0032] Furthermore, a cover is hinged to one side of the top of the toilet seat, and several ultraviolet disinfection lamps are fixedly connected to one side of the cover.

[0033] Beneficial effects: The ultraviolet disinfection lamp can disinfect and sterilize the inside of the toilet bowl, effectively killing bacteria, viruses, and other microorganisms, thus improving hygiene. The lid is rotatably connected to the toilet bowl, allowing for easy opening and closing, facilitating cleaning and disinfection for users.

[0042] The following detailed description illustrates the specific implementation methods:

[0043] Example 1:

[0044] As attached Figure 1 To be continued Figure 3 The following describes an automatic excrement sampling device for gastroenterology: It includes a hollow toilet bowl 1 with a top opening 4. An infrared sensor 2 is fixedly connected to the inside of the toilet bowl 1 by screws. The infrared sensor 2 detects the temperature distribution of the excrement and is connected to a controller. Several lifting components are located at the bottom of the toilet bowl 1, each connected to the controller. A collector is fixedly connected to each lifting component. The collector includes a collection chamber 3 with an opening 4 at the top. A sealing plate 5 is slidably connected to one side of the opening 4. The sealing plate 5 is slidably connected to the inner top wall of the collection chamber 3 via a slide rail and a slide groove. A first transmission assembly is provided between the sealing plate 5 and the lifting components. This first transmission assembly is used to move the sealing plate 5 to open the opening 4 when the lifting components are raised.

[0045] The first transmission component includes a rack 6 and a gear 7. The collection chamber 3 has a slot 8 on the side near the inner wall of the toilet bowl 1. The rack 6 is located in the slot 8 and is fixedly connected to the inner wall of the toilet bowl 1. The gear 7 is rotatably connected to the collection chamber 3 and meshes with the rack 6. A connecting rod 9 is hinged to one side of the gear 7. The end of the connecting rod 9 away from the gear 7 is rotatably connected to one side of the sealing plate 5.

[0046] A bracket 10 is fixedly connected inside the collection chamber 3. A collection bag 11 is fitted on the bracket 10 with the opening of the collection bag 11 facing the opening 4. A movable part is provided on one side of the bracket 10. The movable part is used to tighten the collection bag 11. A baffle 12 is provided below the collection bag 11. The baffle 12 is a wedge-shaped block with an inclined upper surface. The baffle 12 is vertically slidably connected to the inner wall of the collection chamber 3. A second transmission component is provided between the movable part and the baffle 12. The second transmission component is used to tighten the collection bag 11 when the baffle 12 moves downward.

[0047] The second transmission assembly includes a first rod 13, a second rod 14, a first slider 15, and a second slider 16. The first rod 13 and the first slider 15 are located on one side of the baffle 12, and the second rod 14 and the second slider 16 are located on the other side of the baffle 12. The two sides of the first rod 13 are rotatably connected to the baffle 12 and the first slider 15, respectively. The two sides of the second rod 14 are rotatably connected to the baffle 12 and the second slider 16, respectively. The first slider 15 and the second slider 16 are both laterally slidably connected to the bracket 10. The moving part includes a first locking block 17 and a second locking block 18. The first locking block 17 is fixedly connected to the side of the first slider 15 near the second slider 16, and the second locking block 18 is fixedly connected to the side of the second slider 16 near the first slider 15. A heating element 22 is embedded in the second locking block 18.

[0048] The specific implementation process is as follows:

[0049] I. Preparation Stage

[0050] Check the equipment:

[0051] Ensure that the toilet seat 1, infrared sensor 2, controller, lifting mechanism, collector, and other components are all intact and in normal working order.

[0052] Check that the collection bag 11 is correctly installed on the bracket 10 and ensure that its opening 4 is aligned with the opening 4 of the collection chamber 3.

[0053] Patient preparation:

[0054] The patient sits on the commode 1 as usual, preparing to defecate.

[0055] Medical staff or patients' families can explain the usage and precautions of the equipment to the patients in advance to ensure that the patients can cooperate in completing the sampling process.

[0056] II. Excretion and Detection Phase

[0057] Start excretion:

[0058] During the normal defecation process, the excrement falls into the toilet bowl 1.

[0059] Infrared sensor 2 detection:

[0060] Infrared sensor 2 monitors the temperature distribution inside toilet bowl 1 in real time. When it detects the temperature information of the excrement, it transmits the signal to the controller.

[0061] The controller determines the position:

[0062] Based on the received temperature information, the controller uses an algorithm to accurately determine the specific location of the excrement.

[0063] Control the lifting components to rise:

[0064] Based on the judgment result, the controller controls the lifting component below the corresponding position to rise. The rising of the lifting component generates a thrust on the excrement, making it easier for it to fall into the collector.

[0065] The first transmission component is operating:

[0066] As the lifting component rises, the rack 6 fixed to the inner wall of the toilet bowl 1 meshes with the gear 7 inside the collection chamber 3.

[0067] The rotation of gear 7 drives the sealing plate 5 to open automatically via connecting rod 9, revealing the opening 4 of the collection chamber 3.

[0068] Excrement falls into collection bag 11:

[0069] Under the influence of gravity, the excrement falls accurately into the collection bag 11 through the open opening 4.

[0070] III. Packaging and Collection Stage

[0071] The weight of collection bag 11 has increased:

[0072] As excrement continues to fall in, the weight inside the collection bag 11 gradually increases.

[0073] Baffle 12 moves downward:

[0074] The pressure on the baffle 12 at the bottom of the collection bag 11 increases, causing the baffle 12 to move vertically downward.

[0075] The second transmission component is in operation:

[0076] The baffle 12 drives the first slider 15 and the second slider 16 to slide laterally on the bracket 10 via the first rod 13 and the second rod 14.

[0077] At the same time, the first card block 17 and the second card block 18 move closer to the middle, tightening and clamping the collection bag 11.

[0078] Heating element 22 sealing:

[0079] When the first clamping block 17 and the second clamping block 18 come together to clamp the collection bag 11, the heating element 22 heats and melts the bag opening to seal it. After sealing, due to the inclination of the upper surface of the inclined baffle 12, the collection bag 11, under the action of gravity, overcomes the tension of the top support 10 and the friction of the baffle 12, resulting in a downward sliding tendency. At the same time, when the baffle 12 moves down and completes the sealing through the second transmission assembly, the connection between the collection bag 11 and the support 10 is released or loosened, and under the action of the gravity component, it slides down the inclined baffle 12 to the guide plate 24, realizing automatic unloading.

[0080] IV. Follow-up Processing Stage

[0081] Take out collection bag 11:

[0082] Medical staff can easily remove the sealed collection bag 11 for subsequent laboratory testing or other treatments.

[0083] Cleaning equipment:

[0084] After use, clean and disinfect the toilet bowl 1, collection container, and other components to ensure they function properly and meet hygiene standards for the next use.

[0085] Records and feedback:

[0086] Medical staff should record relevant information about the sampling process, such as the sampling time and patient information, and send this information along with the collection bag 11 to the laboratory for testing.

[0087] At the same time, medical staff should also provide feedback on the equipment based on its usage so that problems can be identified and resolved in a timely manner.

[0088] Example 2:

[0089] As attached Figure 1 To be continued Figure 3 As shown, the difference from Embodiment 1 is that a water tank 19 is fixedly connected to one side of the toilet bowl 1, an infusion pipe 20 is connected to the water tank 19, the infusion pipe 20 is connected to the toilet bowl 1, a water pump 21 is connected to the infusion pipe 20, the water pump 21 is connected to the controller signal, and a water outlet is connected to one side of the toilet bowl 1.

[0090] The bottom of the collection chamber 3 has an opening on one side, and a door 23 is hinged to one side of the opening. The door 23 is electrically operated and connected to the controller. An inclined guide plate 24 is fixedly connected to the bottom inside the collection chamber 3. The side of the guide plate 24 with a higher height is fixedly connected to the side away from the door 23, and the side of the guide plate 24 with a lower height is fixedly connected to the side close to the door 23.

[0091] A camera 25 is embedded on one side of the toilet bowl 1. The camera 25 is connected to a controller, which in turn is connected to a terminal device. The camera 25 is used to acquire image information of the excrement and transmits the image information to the terminal device using the controller. Several springs 31 are fixedly connected to the bottom of the baffle 12, and the bottom ends of the springs 31 are all fixedly connected to the bracket 10. The lifting component includes an electromagnet 26 and an iron block 27. The electromagnet 26 is fixedly connected to the bottom wall of the toilet bowl 1, and the iron block 27 is embedded in the bottom wall of the collection compartment 3.

[0092] A battery pack 30 and a charging interface are fixedly connected to one side of the bottom of the toilet seat 1. The battery pack 30 is used to provide power support for the entire device, and the charging interface is used to connect an external power source to charge the battery pack 30. The power management module is also used for power monitoring. When the power is lower than the preset value, the controller will activate a low power alarm and transmit the alarm information to the terminal device.

[0093] A cover 28 is hinged to one side of the top of the toilet seat 1, and several ultraviolet disinfection lamps 29 are fixedly connected to one side of the cover 28.

[0094] The specific implementation process is as follows:

[0095] I. Preparation Stage

[0096] Equipment inspection:

[0097] Ensure that the toilet seat 1, water tank 19, infusion tube 20, water pump 21, controller, lifting components (electromagnet 26 and iron block 27), collector, camera 25, battery pack 30, charging interface, ultraviolet disinfection lamp 29 and other components are all intact and in normal working condition.

[0098] Check that the collection bag 11 is correctly installed on the bracket 10 and ensure that its opening 4 is aligned with the opening 4 of the collection chamber 3.

[0099] Ensure the battery pack has sufficient charge. If the charge is insufficient, you can connect an external power source to charge it via the charging port.

[0100] Environmental preparation:

[0101] Ensure that the area where toilet seat 1 is located is clean and tidy, free from clutter.

[0102] If disinfection of the toilet seat 1 is required, it can be pre-treated using an ultraviolet disinfection lamp 29.

[0103] Patient preparation:

[0104] The patient sits on the toilet seat 1 in the usual manner, with the lid 28 kept open for defecation.

[0105] Medical staff or patients' families can explain the usage and precautions of the equipment to the patients in advance to ensure that the patients can cooperate in completing the sampling process.

[0106] II. Excretion and Detection Phase

[0107] Start excretion:

[0108] During the normal defecation process, the excrement falls into the toilet bowl 1.

[0109] Infrared sensor 2 and camera 25 detect:

[0110] Infrared sensor 2 monitors the temperature distribution inside toilet bowl 1 in real time. When it detects the temperature information of the excrement, it transmits the signal to the controller.

[0111] At the same time, camera 25 acquires image information of the excrement and transmits the image information to the controller, which then transmits the image information to the terminal device (such as a doctor's workstation).

[0112] Controller determines location and starts water pump 21:

[0113] Based on the received temperature information, the controller uses an algorithm to accurately determine the specific location of the excrement.

[0114] If flushing of excrement is required, the controller can start the water pump 21 to inject clean water into the toilet bowl 1 through the infusion tube 20.

[0115] Control the lifting components to rise:

[0116] Based on the judgment result, the controller controls the lifting component (electromagnet 26) below the corresponding position to be energized, attracting the iron block 27 to drive the collection chamber 3 to rise.

[0117] The rising of the lifting component creates a thrust on the excrement, making it easier for it to fall into the collector.

[0118] The first transmission component is operating:

[0119] As the lifting component rises, the rack 6 fixed to the inner wall of the toilet bowl 1 meshes with the gear 7 inside the collection chamber 3.

[0120] The rotation of gear 7 drives the sealing plate 5 to open automatically via connecting rod 9, revealing the opening 4 of the collection chamber 3.

[0121] Excrement falls into collection bag 11:

[0122] Under the influence of gravity, the excrement falls accurately into the collection bag 11 through the open opening 4.

[0123] III. Packaging and Collection Stage

[0124] The weight of collection bag 11 increases and the baffle 12 moves:

[0125] As excrement continues to fall in, the weight inside the collection bag 11 gradually increases, causing the spring 31 at the bottom of the baffle 12 to be compressed.

[0126] When the weight inside the collection bag 11 reaches a certain value, the baffle 12 will move vertically downwards.

[0127] The second transmission component is in operation:

[0128] The baffle 12 drives the first slider 15 and the second slider 16 to slide laterally on the bracket 10 via the first rod 13 and the second rod 14.

[0129] At the same time, the first card block 17 and the second card block 18 move closer to the middle, tightening and clamping the collection bag 11.

[0130] Heating element 22 sealing:

[0131] When the first locking block 17 and the second locking block 18 come together and clamp the collection bag 11, the heating element 22 embedded in the first locking block 17 quickly heats up and melts the material of the collection bag 11, thereby achieving a reliable sealing effect.

[0132] Door 23 opening and excrement collection:

[0133] After the collection bag 11 is sealed, the door 23 at the bottom of the collection chamber 3 can be opened manually or automatically, allowing the collection bag 11 to slide out from the opening.

[0134] Medical staff can easily remove the sealed collection bag 11 for subsequent laboratory testing or other treatments.

[0135] IV. Rinsing and Disinfection Stage

[0136] Water pump 21 flushing:

[0137] If the toilet bowl 1 needs to be flushed, the water pump 21 can be restarted to inject clean water into the toilet bowl 1 through the infusion tube 20.

[0138] After rinsing, the wastewater can be discharged through the outlet.

[0139] Ultraviolet disinfection:

[0140] After rinsing, the ultraviolet disinfection lamp 29 on top of the toilet seat 1 can be turned on to disinfect the inside of the toilet seat 1.

[0141] The ultraviolet disinfection lamp 29 can effectively kill bacteria, viruses and other microorganisms, ensuring the hygiene and safety of the toilet seat 1.

[0142] V. Subsequent Processing and Maintenance Phase

[0143] Equipment cleaning:

[0144] After use, clean and disinfect the toilet bowl 1, collection container, and other components to ensure they function properly and meet hygiene standards for the next use.

[0145] Battery pack 30 charging:

[0146] If the battery pack's charge is low, it can be charged by connecting an external power source through the charging port.

[0147] The power management module monitors the battery level and, when the battery level falls below a preset value, initiates a low battery alarm via the controller and transmits the alarm information to the terminal device.

[0148] Equipment maintenance:

[0149] Medical staff should regularly maintain and service the equipment, including checking the connections, cleanliness, and lubrication of each component.

[0150] If any parts are found to be damaged or malfunctioning, they should be replaced or repaired promptly.

[0151] Records and feedback:

[0152] Medical staff should record relevant information about the sampling process, such as sampling time and patient information. They should also provide feedback on the equipment based on usage to promptly identify and resolve any issues.

[0153] Example 3:

[0154] Each collection chamber 3 is fixedly connected with an electric push rod (not shown in the figure). The electric push rod is connected to the controller. When the collection bag 11 is finished being packaged, the controller controls the electric push rod to extend and push the packaged collection bag 11 off the baffle 12, so that the collection bag 11 falls onto the guide plate 24.

[0155] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
