Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an automatic excrement sampling device for gastroenterology. Background Art

[0002] Obtaining fecal samples from patients is a common diagnostic procedure in healthcare settings, particularly during clinical examinations in gastroenterology. These samples are valuable for analyzing a patient's intestinal health, digestive system function, and potential diseases. However, traditional fecal sampling methods often rely on visual observation and manual manipulation by patients or medical staff. This not only increases sampling difficulty and inaccuracies but also introduces the risk of cross-infection, impacting the efficiency of healthcare services and the patient experience.

[0003] Currently, there are some excrement sampling devices on the market, but most of them still use more traditional methods. For example, some devices require patients to take samples of excrement by themselves and put them into a container, which is then sent to the laboratory for testing by medical staff. This method is not only cumbersome to operate, but also prone to contamination or errors during the sampling process. At the same time, traditional sampling methods require patients or medical staff to perform manual operations, which not only increases the workload, but may also lead to inaccurate sampling due to improper operation. During the sampling process, patients or medical staff may directly contact excrement, thereby increasing the risk of cross-infection. Therefore, this proposal proposes an automatic excrement sampling device for gastroenterology. Summary of the Invention

[0004] In order to solve the above problems, the present invention provides an automatic excrement sampling device for gastroenterology, which is used for convenient excrement sampling and can reduce the risk of cross infection.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an automatic excrement sampling device for gastroenterology, comprising a toilet box, an infrared sensor fixedly connected to the inner wall of the toilet box, the infrared sensor being used to detect the temperature distribution of excrement, the infrared sensor signal being connected to a controller, a plurality of lifting members being provided at the bottom of the toilet box, the lifting members being all connected to the controller signal, when the infrared sensor detects an excrement signal, the infrared sensor transmits the acquired excrement information to the controller, the controller controls the operation of the lifting members based on the excrement information, and a collector is fixedly connected to each lifting member;

[0006] The collector includes a collecting bin, an opening is provided at the top of the collecting bin, a sealing plate is slidably connected to one side of the opening, a first transmission assembly is provided between the sealing plate and the lifting member, the first transmission assembly is used to move the sealing plate to open the opening when the lifting member is raised; a bracket is fixedly connected in the collecting bin, a collecting bag is provided on the bracket, a moving member is provided on one side of the bracket, the moving member is used to tighten the collecting bag, a baffle is provided under the collecting bag, the baffle is vertically slidably connected to the inner wall of the collecting bin, a second transmission assembly is provided between the moving member and the baffle, the second transmission assembly is used to tighten the collecting bag when the baffle moves downward.

[0007] The technical principle of the above scheme is as follows: When a patient needs to obtain a fecal sample during a gastroenterology examination, the patient can sit on the toilet box to defecate, allowing the feces to fall into the toilet box. At this time, the infrared sensor obtains the temperature information inside the toilet box and transmits the temperature information to the controller. The controller determines the falling position of the feces based on the temperature information and controls the lifting member at the corresponding position to rise. When the lifting member rises, the first transmission component is used to move 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 in 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 member to move through the second transmission component, causing the moving member to tighten the collection bag and complete the packaging of the feces.

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

[0009] 1. This solution uses infrared sensors to monitor the temperature distribution inside the toilet bowl in real time, accurately determining the location of excrement. This intelligent design eliminates errors caused by manual judgment and ensures accurate sampling. The lifting element automatically rises in response to controller commands, generating thrust against the excrement, facilitating collection. The first transmission assembly then automatically opens the sealing plate, allowing the excrement to fall accurately into the collection bag. This process requires no human intervention, enhancing operational convenience.

[0010] 2. This solution uses infrared sensors to detect the temperature distribution of excrement, enabling precise identification of the location of excrement. This positioning method is more accurate than traditional visual observation, ensuring precise sampling. A controller controls the riser to align the collection bag with the excrement, further improving sampling accuracy.

[0011] 3. This solution's automatic sampling device prevents direct contact between patients and medical staff and reduces the risk of cross-infection, improving hygiene. After collecting excreta, the collection bag automatically tightens and closes via a moving element, effectively preventing leakage and odor, ensuring a clean and comfortable environment while also reducing the risk of cross-infection.

[0012] 4. With this solution, patients only need to sit on the toilet to defecate, without any additional operation, to complete the sampling process. This design greatly simplifies the sampling process and improves the patient experience. The various components of the device are rationally designed and easy to disassemble and clean, facilitating daily maintenance work for medical staff.

[0013] 5. This solution uses an automatic 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 used in other medical examinations that require fecal samples, and has a wide range of practical value.

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

[0015] Furthermore, the first transmission member includes a rack and a gear. A slot is provided on the side of the collection bin close to the inner wall of the toilet box. The rack is located in the slot. The rack is fixedly connected to the inner wall of the toilet box. The gear is rotatably connected to the collection bin. The gear is meshed with the rack. One side of the gear is rotatably connected to a connecting rod, and the connecting rod is hinged to one side of the sealing plate at one end away from the gear.

[0016] Beneficial Effects: The compact meshing structure of the rack and gear effectively converts the vertical motion of the lifting member (such as the collection bin) into the rotation of the gear. The ingenious design of the connecting rod further converts the rotation of the gear into the opening and closing of the sealing plate, making the entire transmission process efficient and smooth. Without manual intervention, when the lifting member rises, the rack moves and meshes with the gear, driving the connecting rod and the sealing plate to automatically open. This automated operation reduces the complexity and errors of manual operation and improves 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 in the shape of a wedge 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, and the first slider and the second slider are both laterally slidably connected to the bracket; the moving part includes a first clamping block and a second clamping block, the first clamping block is fixedly connected to the side of the first slider close to the second slider, the second clamping block is fixedly connected to the side of the second slider close to the first slider, and a heating element is embedded in the second clamping block.

[0018] Beneficial Effects: 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 bracket, a simple yet effective transmission mechanism is constructed. The design of the first and second clamping blocks cleverly achieves both tightening and sealing 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 via the first and second rods to the first and second sliders, driving the first and second clamping blocks toward each other. This series of actions requires no human intervention, achieving automated operation and improving sampling efficiency and accuracy. A heating element is embedded in the first clamping block. When the first and second clamping blocks come together and clamp the collection bag, the heating element rapidly heats and melts the material of the collection bag, achieving a reliable seal. This sealing method is both secure and aesthetically pleasing, effectively preventing sample leakage and contamination. Because the entire transmission and sealing process is automated, direct contact between medical staff and excrement is minimized. This not only protects medical staff safety but also reduces the risk of cross-infection.

[0019] When the sealing is completed, the inclined baffle provides a gravity component for the collection bag, causing it to slide along the inclination direction of the baffle. Since the upper surface of the baffle is inclined, the collection bag is under the action of its own gravity, and the gravity component along the inclined surface of the baffle will overcome the tension of the top bracket and the friction of the bottom baffle, forming a downward sliding trend. At the same time, when the baffle moves downward, the second transmission assembly completes the tightening and sealing of the collection bag. At this time, the connection between the collection bag and the bracket is released or loosened. Under the action of the gravity component, the collection bag slides smoothly along the inclined baffle to the guide plate, realizing automatic unloading. This design utilizes the gravity component and the inclined structure of the baffle to ensure that the collection bag can slide reliably after sealing, avoiding failure to fall due to unstable weight, improving the automation and reliability of the sampling device, and ensuring the continuity of the sampling process.

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

[0021] Beneficial Effects: This design enables the toilet to automatically flush after sampling, maintaining cleanliness and hygiene. The water pump controls the intensity and duration of the flushing water flow to ensure effective flushing. The pump is connected to the controller for signal processing, enabling automatic flushing. When sampling is complete, the controller automatically sends a signal to the pump to initiate the flushing process, eliminating the need for manual intervention. By precisely controlling the pump's operating time and flushing water flow intensity, water waste is effectively reduced. This not only aligns with environmental principles but also reduces operating costs.

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

[0023] Beneficial effects: The guide plate and the through port can facilitate the directional output of the collection bag, thereby improving the output efficiency.

[0024] Furthermore, a camera is embedded in one side of the toilet box, the camera is connected to the controller signal, the controller signal is connected to the terminal device, the camera is used to obtain image information of the excrement, and the controller is used to transmit the image information to the terminal device.

[0025] Beneficial effects: The camera can obtain image information of excrement in real time and transmit it to the terminal device. Doctors or medical professionals can remotely view the status of excrement through the terminal device to make a preliminary diagnosis or evaluation. This real-time monitoring function helps to promptly detect possible digestive system problems or diseases in patients and provide patients with timely treatment recommendations. Through the excrement image information obtained by the camera, doctors can more intuitively observe the color, shape, texture and other characteristics of the excrement. These characteristics are of great reference value for diagnosing certain digestive system diseases and help improve the accuracy of diagnosis. Traditional excrement sampling methods often require patients to take samples themselves and send them to the hospital for testing. During this process, there may be problems such as inaccurate sampling or sample contamination. The method of automatically obtaining excrement image information through the camera can avoid these problems and reduce errors in manual sampling.

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

[0027] Beneficial effects: The spring acts as a buffer and shock absorber. When excrement falls into the collection bin, the spring absorbs the impact. At the same time, when the collection bag is output, the pressure on the spring disappears and the baffle automatically returns to its original position, facilitating the next collection operation.

[0028] Furthermore, the lifting member includes an electromagnet and an iron block, the electromagnet is fixedly connected to the bottom wall of the toilet box, and the iron block is embedded in the bottom wall of the collection bin.

[0029] Beneficial effect: Through the cooperation of the electromagnet and the iron block, the efficient lifting function of the collection bin can be achieved. The lifting of the electromagnet and the iron block can be automatically controlled by the controller, which improves the convenience of use.

[0030] Furthermore, a battery pack and a charging port are fixedly connected to one side of the bottom of the toilet box. The battery pack is used to provide power support for the entire device, and the charging port is used to connect an external power supply 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 low power alarm is activated through the controller and the alarm information is transmitted to the terminal device.

[0031] Beneficial Effects: The battery pack provides power for the entire device, ensuring its continued operation even in power outages. The charging port allows the battery pack to be easily connected to an external power source for charging, ensuring continued device operation. The power management module's power monitoring function monitors the battery pack's charge level in real time and activates a low-battery alarm when the charge level falls below a preset value, reminding the user to recharge promptly to prevent the device from shutting down due to depletion.

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

[0033] Beneficial effects: The UV disinfection lamp can sterilize the inside of the toilet, effectively killing bacteria, viruses and other microorganisms, and improving hygiene. The lid is rotatably connected to the toilet and can be easily opened or closed, making it easier for users to clean and disinfect.

[0042] The following is further described in detail through specific implementation methods:

[0043] Example 1:

[0044] As attached Figure 1 To the attached Figure 3 As shown: An automatic excrement sampling device for gastroenterology, comprising a hollow toilet box 1 with an opening 4 at the top. An infrared sensor 2 is fixedly connected to the inside of the toilet box 1 by screws. The infrared sensor 2 is used to detect the temperature distribution of excrement. The infrared sensor 2 signal is connected to a controller. A number of lifting parts are provided at the bottom of the toilet box 1. The lifting parts are all connected to the controller signal. A collector is fixedly connected to each lifting part. The collector comprises a collecting bin 3. An opening 4 is provided at the top of the collecting bin 3. 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 collecting bin 3 by means of a slide rail and a slide groove. A first transmission assembly is provided between the sealing plate 5 and the lifting part. The first transmission assembly is used to move the sealing plate 5 to open the opening 4 when the lifting part is raised.

[0045] The first transmission member includes a rack 6 and a gear 7. A slot 8 is provided on the side of the collection bin 3 close to the inner wall of the toilet box 1. The rack 6 is located in the slot 8. The rack 6 is fixedly connected to the inner wall of the toilet box 1. The gear 7 is rotatably connected to the collection bin 3. The gear 7 is meshed with the rack 6. A connecting rod 9 is hinged on one side of the gear 7. The connecting rod 9 is rotatably connected to one side of the sealing plate 5 at the end away from the gear 7.

[0046] A bracket 10 is fixedly connected to the collecting bin 3, and a collecting bag 11 is sleeved on the bracket 10. The bag mouth of the collecting bag 11 faces the opening 4. A moving part is provided on one side of the bracket 10, and the moving part is used to tighten the collecting bag 11. A baffle 12 is provided under the collecting 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 collecting bin 3. A second transmission assembly is provided between the moving part and the baffle 12. The second transmission assembly is used to tighten the collecting 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 first rod 13 is rotatably connected to the baffle 12 and the first slider 15 on both sides, and the second rod 14 is rotatably connected to the baffle 12 and the second slider 16 on both sides. The first slider 15 and the second slider 16 are both laterally slidably connected to the bracket 10; the moving part includes a first clamping block 17 and a second clamping block 18. The first clamping block 17 is fixedly connected to the side of the first slider 15 close to the second slider 16, and the second clamping block 18 is fixedly connected to the side of the second slider 16 close to the first slider 15. A heating element 22 is embedded in the second clamping block 18.

[0048] The specific implementation process is as follows:

[0049] 1. Preparation

[0050] Check the equipment:

[0051] Ensure that the toilet box 1, infrared sensor 2, controller, lifting parts, collector and other components are intact and in normal working condition.

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

[0053] Patient preparation:

[0054] The patient sits on the toilet box 1 in a conventional manner and prepares to defecate.

[0055] Medical staff or the patient's family can explain to the patient in advance how to use the equipment and precautions to ensure that the patient can cooperate with the sampling process.

[0056] 2. Excretion and Detection Stage

[0057] Start defecation:

[0058] The patient performs a normal excretion process, and the excrement falls into the toilet box 1.

[0059] Infrared sensor 2 detects:

[0060] The infrared sensor 2 monitors the temperature distribution in the toilet box 1 in real time, and transmits a signal to the controller when the temperature information of the excrement is detected.

[0061] The controller determines the position:

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

[0063] Control the lifting part to rise:

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

[0065] The first transmission component works:

[0066] As the lifting member rises, the rack 6 fixed to the inner wall of the toilet box 1 engages with the gear 7 in the collection bin 3.

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

[0068] Excreta falls into the collection bag 11:

[0069] Under the action of gravity, the excrement falls accurately into the collecting bag 11 through the opened opening 4 .

[0070] 3. Packaging and Collection Phase

[0071] The weight of the collecting bag 11 increases:

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

[0073] The baffle 12 moves downward:

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

[0075] Second transmission assembly works:

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

[0077] At the same time, the first clamping block 17 and the second clamping block 18 move toward the center to tighten and clamp the collecting bag 11 .

[0078] Heating element 22 sealing:

[0079] When the first and second clamps 17, 18 close together to clamp the collection bag 11, the heating element 22 heats and melts the bag opening, sealing it. After sealing, the inclined baffle 12, due to its tilted upper surface, causes the collection bag 11 to slide downward under the influence of gravity. The force of gravity along the inclined surface of the baffle 12 overcomes the tension of the top bracket 10 and the friction of the baffle 12, causing it to slide downward. Simultaneously, as the baffle 12 moves downward through the second transmission assembly to complete the sealing, the connection between the collection bag 11 and the bracket 10 is released or loosened. Under the influence of gravity, the bag slides along the inclined baffle 12 to the guide plate 24, achieving automatic unloading.

[0080] 4. Subsequent processing stage

[0081] Remove the collection bag 11:

[0082] Medical personnel can conveniently remove the sealed collection bag 11 for subsequent laboratory testing or other processing.

[0083] Cleaning equipment:

[0084] After use, clean and disinfect the toilet box 1, collector and other components to ensure that they can work normally and meet hygiene standards the next time they are used.

[0085] Recording and feedback:

[0086] Medical personnel should record relevant information of the sampling process, such as sampling time, patient information, etc., and send this information together 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 usage so that problems can be discovered and resolved in a timely manner.

[0088] Example 2:

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

[0090] A through opening is provided on one side of the bottom of the collecting bin 3, and a door body 23 is hinged on one side of the through opening. The door body 23 is electrically opened and closed, and the door body 23 is connected to the controller signal. The bottom of the collecting bin 3 is fixedly connected with an inclined guide plate 24, and the side of the guide plate 24 with a higher height is fixedly connected to the side away from the door body 23, and the side of the guide plate 24 with a lower height is fixedly connected to the side close to the door body 23.

[0091] A camera 25 is embedded in one side of the toilet bowl 1. This camera 25 is connected to a controller, which in turn is connected to a terminal device. The camera 25 is used to capture images of excrement and transmit them to the terminal device via the controller. Several springs 31 are fixedly attached to the bottom of the baffle 12, each of which is fixedly connected to the bracket 10. The lifting mechanism includes an electromagnet 26 and an iron block 27. The electromagnet 26 is fixedly attached to the bottom wall of the toilet bowl 1, while the iron block 27 is embedded in the bottom wall of the collection bin 3.

[0092] A battery pack 30 and a charging interface are fixedly connected to one side of the bottom of the toilet box 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 supply 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 low power alarm is activated through the controller and the alarm information is transmitted to the terminal device.

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

[0094] The specific implementation process is as follows:

[0095] 1. Preparation

[0096] Equipment inspection:

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

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

[0099] Ensure that the battery pack 30 is fully charged. If the battery is insufficient, it can be charged by connecting it to an external power source through the charging port.

[0100] Environmental preparation:

[0101] Make sure the area where the toilet box 1 is located is clean and tidy, without any interference from debris.

[0102] If the toilet box 1 needs to be disinfected, an ultraviolet disinfection lamp 29 can be used for pretreatment.

[0103] Patient preparation:

[0104] The patient sits on the toilet box 1 in a conventional manner, and the cover 28 can remain open for defecation.

[0105] Medical staff or the patient's family can explain to the patient in advance how to use the equipment and precautions to ensure that the patient can cooperate with the sampling process.

[0106] 2. Excretion and Detection Stage

[0107] Start defecation:

[0108] The patient performs a normal excretion process, and the excrement falls into the toilet box 1.

[0109] Infrared sensor 2 and camera 25 detect:

[0110] The infrared sensor 2 monitors the temperature distribution in the toilet box 1 in real time, and transmits a signal to the controller when the temperature information of the excrement is detected.

[0111] At the same time, the camera 25 obtains 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] The controller determines the position and starts the water pump 21:

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

[0114] If it is necessary to flush the excrement, the controller can control the water pump 21 to start and inject clean water into the toilet box 1 through the infusion tube 20.

[0115] Control the lifting part to rise:

[0116] According to the judgment result, the controller controls the lifting member (electromagnet 26) below the corresponding position to be energized, attracting the iron block 27 to drive the collecting bin 3 to rise.

[0117] The lifting of the lifting member will generate a pushing force on the excrement, making it easier for it to fall into the collector.

[0118] The first transmission component works:

[0119] As the lifting member rises, the rack 6 fixed to the inner wall of the toilet box 1 engages with the gear 7 in the collection bin 3.

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

[0121] Excreta falls into the collection bag 11:

[0122] Under the action of gravity, the excrement falls accurately into the collecting bag 11 through the opened opening 4 .

[0123] 3. Packaging and Collection Phase

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

[0125] As the excrement continues to fall into the collection bag 11 , 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 in the collection bag 11 reaches a certain value, the baffle 12 will move vertically downward.

[0127] Second transmission assembly works:

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

[0129] At the same time, the first clamping block 17 and the second clamping block 18 move toward the center to tighten and clamp the collecting bag 11 .

[0130] Heating element 22 sealing:

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

[0132] Door 23 opening and excrement collection:

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

[0134] Medical personnel can conveniently remove the sealed collection bag 11 for subsequent laboratory testing or other processing.

[0135] 4. Flushing and disinfection stage

[0136] Water pump 21 flushing:

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

[0138] After flushing is completed, the waste water can be discharged through the outlet.

[0139] Ultraviolet disinfection:

[0140] After the flushing is completed, the ultraviolet disinfection lamp 29 on the top of the toilet box 1 can be turned on to disinfect the inside of the toilet box 1.

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

[0142] 5. Subsequent processing and maintenance stage

[0143] Equipment cleaning:

[0144] After use, clean and disinfect the toilet box 1, collector and other components to ensure that they can work normally and meet hygiene standards the next time they are used.

[0145] Battery Pack 30 Charging:

[0146] If the battery pack 30 is low on power, it can be charged by connecting it to an external power source through the charging interface.

[0147] The power management module monitors the power status and activates a low-battery alarm through the controller when the power is lower than a preset value 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 connection, cleanliness, and lubrication of each component.

[0150] If any parts are found to be damaged or faulty, they should be replaced or repaired in a timely manner.

[0151] Recording and feedback:

[0152] Medical staff should record relevant information of the sampling process, such as sampling time, patient information, etc. At the same time, medical staff should also provide feedback on the equipment based on usage so that problems can be discovered and resolved in a timely manner.

[0153] Example 3:

[0154] An electric push rod (not shown in the figure) is fixedly connected to the collection bin 3, and the electric push rod is connected to the controller signal. When the collection bag 11 is packed, the controller controls the electric push rod to extend, and pushes the packed collection bag 11 from the baffle 12, so that the collection bag 11 falls onto the guide plate 24.

[0155] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
