Description

Technical Field

[0001] This invention relates to the field of medical waste bins, and more specifically, to an intelligent infectious medical waste bin. Background Technology

[0002] In healthcare facilities, the disposal of infectious medical waste is a critical issue. Traditional medical waste bins typically require manual processes such as changing and sealing the bags, which is not only inefficient but also increases the risk of healthcare workers coming into contact with sources of infection. Furthermore, medical waste may emit odors and breed bacteria during collection, posing a potential threat to the environment and human health.

[0003] While some smart trash cans have emerged in the existing technology, they still have many shortcomings in meeting the special needs of medical infectious waste disposal, such as contactless automatic bag retrieval, bag unfolding, bag opening separation, automatic sealing, and internal environment disinfection and purification. The process of retrieving and unfolding the trash bags often requires manual intervention, or the degree of automation is low, easily leading to bag retrieval failures. Therefore, we propose a smart infectious medical waste can. Summary of the Invention

[0004] This invention provides an intelligent medical waste bin that solves the technical problem in related technologies where manual intervention is often required or the degree of automation is low during the retrieval and unfolding of waste bags, which easily leads to bag retrieval failure.

[0005] This invention provides an intelligent medical waste bin, comprising: an intelligent waste bin, wherein the intelligent waste bin is provided with an internal processing mechanism for processing the waste bags before and after use; The internal processing mechanism includes an internal component box, a bag-retrieving plate, a bag-spreading plate, a power supply component, and a pre-storage component. The internal component box is fixed to the bottom of the smart trash can. The bag-retrieving plate and the bag-spreading plate are both rotatably mounted on the internal component box, and both have lifting functions. The top surfaces of the bag-retrieving plate and the bag-spreading plate are both inclined surfaces and are arranged facing each other. The pre-stored components are fixed to the side wall of the smart trash can for vertically hanging multiple unused trash bags with built-in QR codes; The inclined surface of the bag-taking plate is provided with a bag-taking suction port, and a grinding column is rotatably installed inside the bag-taking suction port; The inclined surface of the bag-distributing plate is provided with a bag-distributing suction port, and a bag-distributing rubbing column is rotatably installed inside the bag-distributing suction port; Both the bag-collecting plate and the bag-spreading plate are connected to the power supply components, and the initial height of the bag-spreading plate is lower than that of the bag-collecting plate; When in use, first control the bag-retrieving plate to rotate so that its inclined surface is in close contact with the outermost garbage bag of the pre-stored component. The power supply component provides negative pressure suction force to make the garbage bag adhere to the bag-retrieving suction port. Then the bag-retrieving plate rotates back to the initial position. Next, control the bag-spreading plate to rise and rotate, so that its inclined surface is in close contact with the garbage bag that has been sucked up by the bag-removing suction port. The bag-spreading suction port sucks up the garbage bag, and then the crushing column and the bag-spreading rubbing column rotate synchronously to crush the two sides of the garbage bag to achieve separation. Finally, control the bag-spreading plate to return to its original position to open the garbage bag opening.

[0006] Furthermore, the smart trash can has a rotating bag-dispensing door on the front, and the opening of the bag-dispensing door is controlled by a smart lock. The top of the smart trash can has a trash-dispensing inlet, and the inside of the trash-dispensing inlet has a rotating automatic door. An electric lock is installed in the direction of the rotating column of the automatic door to control the opening and closing of the automatic door.

[0007] Furthermore, a smart screen module is fixedly installed on the rear side of the garbage disposal opening. Below the smart screen module, inside the smart garbage bin, a camera and a disinfection lamp are fixedly installed, both facing the opening of the garbage bag.

[0008] Furthermore, the internal components box of the container is equipped with an air purifier, a control module, and a drive motor. All three are power supply components. There are two drive motors, and each drive motor has a drive belt on its transmission end. The two drive motors drive the rotation of the bag-taking plate and the bag-spreading plate through the drive belts.

[0009] Furthermore, the air purifier's air intake is equipped with three suction pipes, two of which are connected to the bag-spreading suction port and the bag-removing suction port respectively via flexible hoses, and the suction end of the other is equipped with a bag-swinging negative pressure plate, and the bag-swinging negative pressure plate has several round holes arranged in an array. The bag-swinging negative pressure plate is fixed to the upper wall of the internal component box between the bag-removing plate and the bag-spreading plate.

[0010] Furthermore, the bag-retrieving plate includes a bag-covering swing arm, and the bag-covering swing arm is fixedly connected to the bag-retrieving plate, forming a gantry structure. The bag-covering swing arm includes a first telescopic rod, which divides the bag-covering swing arm into two sections. The extension and retraction of the bag-covering swing arm are controlled by the first telescopic rod, and a first protective rubber sleeve is provided on the outside of the first telescopic rod. The bottom of the bag-covering swing arm is provided with a first rotating wheel that is rotatably connected to the internal component box of the barrel.

[0011] Furthermore, the bag-dispensing plate includes an adjusting arm, and the adjusting arm and the bag-removing plate are in a gantry structure. The adjusting arm includes a second telescopic rod, which divides the adjusting arm into two sections. The extension and retraction of the adjusting arm are controlled by the second telescopic rod. The second telescopic rod is covered with a second protective rubber sleeve. The bottom of the second telescopic rod is provided with a second rotating wheel that is rotatably connected to the internal component box. The extension and retraction diameter of the second telescopic rod is greater than that of the first telescopic rod.

[0012] Furthermore, a heat-sealing opening is provided on the side of the bag-receiving plate near the bag-spreading plate. A plastic sealing heat plate is fixedly installed above the inside of the heat-sealing opening. A bag-pushing plate is fixedly installed at the highest point of the inclined surface of the bag-spreading plate. The bag-pushing plate is made of flexible material and matches the heat-sealing opening.

[0013] Furthermore, flexible grinding arms are fixedly installed on the outer walls of both the bag-spreading and grinding columns, and drive motors are installed below both the bag-spreading and grinding columns to drive them to rotate.

[0014] Furthermore, the pre-storage component includes a bag-holding chamber, the opening of which faces the bag-receiving plate and the bag-spreading plate. The top of the interior of the bag-holding chamber is arrayed with bag-hanging posts, and the top of the bag-hanging posts has a soft barb structure.

[0015] The beneficial effects of this invention are as follows: This invention, by setting up an internal processing mechanism, realizes automatic bag picking, bag unfolding, and bag opening separation of garbage bags, which greatly reduces the direct contact between medical staff and garbage bags and effectively reduces the risk of cross-infection; The inclined surface design of the bag-taking plate and the bag-spreading plate, along with the negative pressure adsorption function, combined with the synchronous rotation of the crushing column and the bag-spreading column, can efficiently and accurately complete the taking of garbage bags and the unfolding of the bag opening, improving the automation and reliability of the operation. The pre-stored components are used to vertically suspend garbage bags with QR codes. Combined with subsequent camera scanning, this enables information-based management and traceability of garbage bags, improving the level of intelligence in medical waste disposal.

[0018] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0019] like Figures 1-8 As shown, an intelligent medical waste bin includes: an intelligent waste bin 11, which has an internal processing mechanism 2 for processing the waste bags before and after use; The internal processing mechanism 2 includes an internal component box 21, a bag-retrieving plate 23, a bag-spreading plate 31, a power supply component, and a pre-storage component. The internal component box 21 is fixed to the bottom of the smart trash can 11. The bag-retrieving plate 23 and the bag-spreading plate 31 are both rotatably mounted on the internal component box 21, and both have lifting functions. The top surfaces of the bag-retrieving plate 23 and the bag-spreading plate 31 are both inclined surfaces and are arranged facing each other. The pre-stored components are fixed to the side wall of the smart trash can 11 for vertically hanging multiple unused trash bags with built-in QR codes; The inclined surface of the bag-taking plate 23 is provided with a bag-taking suction port 28, and a grinding column 29 is rotatably installed inside the bag-taking suction port 28; A bag-displaying suction port 34 is provided on the inclined surface of the bag-displaying plate 31, and a bag-displaying rubbing column 36 is rotatably installed inside the bag-displaying suction port 34. Both the bag-taking plate 23 and the bag-spreading plate 31 are connected to the power supply component, and the initial height of the bag-spreading plate 31 is lower than that of the bag-taking plate 23; When in use, first control the bag-retrieving plate 23 to rotate so that its inclined surface is in close contact with the outermost garbage bag of the pre-stored component. The power supply component provides negative pressure adsorption force to adsorb the garbage bag onto the bag-retrieving suction port 28. Then the bag-retrieving plate 23 rotates back to the initial position. Next, control the bag spreading plate 31 to rise and rotate, so that its inclined surface is in close contact with the garbage bag that has been sucked by the bag taking suction port 28. The bag spreading suction port 34 sucks the garbage bag, and then the crushing column 29 and the bag spreading rubbing column 36 rotate synchronously to crush the two sides of the garbage bag to achieve separation. Finally, control the bag spreading plate 31 to reset to open the garbage bag opening.

[0020] The internal processing unit 2 automates the dispensing, unfolding, and sealing of waste bags, reducing manual handling of the bags, lowering the risk of infection for healthcare workers, and improving the efficiency and hygiene of medical waste management. Furthermore, its integrated design saves space and is suitable for infectious disease healthcare environments.

[0021] The smart trash can 11 has a rotating bag outlet door 12 on its front side, and the opening of the bag outlet door 12 is controlled by a smart lock. The top of the smart trash can 11 has a trash inlet 13, and an automatic door 14 is rotating inside the trash inlet 13. An electric lock 16 is installed in the direction of the rotating column of the automatic door 14 to control the opening and closing of the automatic door 14.

[0022] A smart screen module 15 is fixedly installed on the rear side of the garbage inlet 13. Below the smart screen module 15, inside the smart garbage bin 11, a camera 17 and a disinfection lamp 18 are fixedly installed. Both the camera 17 and the disinfection lamp 18 are facing the opening of the garbage bag.

[0023] Access to the bag outlet 12 and the automatic door 14 is controlled by a smart lock and an electronic lock 16 to prevent unauthorized opening and reduce the leakage of odors and pollutants; the automatic door 14 opens automatically when garbage is disposed of, improving ease of use and hygiene.

[0024] The smart screen module 15 provides a user interface for easy operation and information display, such as garbage bag status and system prompts.

[0025] Camera 17 monitors the garbage disposal process and records the appearance information of the garbage into a QR code, enabling waste traceability and management.

[0026] The disinfection lamp 18 uses ultraviolet light to sterilize the opening and inside of the garbage bag, reducing the risk of microbial contamination.

[0027] The internal components box 21 of the container is equipped with an air purifier 51, a control module 53, and a drive motor 54. The air purifier 51, the control module 53, and the drive motor 54 are all power supply components. There are two drive motors 54, and the transmission ends of the two drive motors 54 are fitted with transmission belts 55. The two drive motors 54 drive the bag picking plate 23 and the bag spreading plate 31 to rotate through the transmission belts 55 respectively.

[0028] The internal component box 21 serves as the core support, integrating key components to create a compact structure that is easy to maintain.

[0029] The inclined surfaces and opposing arrangement of the bag-grabbing plate 23 and the bag-spreading plate 31 facilitate a tight fit with the garbage bag, ensuring accurate grabbing and unfolding.

[0030] The lifting function allows the bag-retrieving plate 23 and the bag-spreading plate 31 to adjust their heights to adapt to different operating stages. For example, when retrieving a bag, the bag-retrieving plate 23 is raised while the bag-spreading plate 31 is initially lower, thus optimizing the workflow.

[0031] Pre-stored components ensure that garbage bags are hung in an orderly manner, and built-in QR codes facilitate information management.

[0032] The bag-grabbing suction port 28 and the bag-spreading suction port 34 use negative pressure to adsorb the garbage bag, achieving non-contact grabbing and reducing pollution.

[0033] The rubbing column 29 and the bag-spreading rubbing column 36 effectively separate the sticky garbage bag openings by rotating and rubbing, improving the reliability of opening the bag openings.

[0034] The air purifier 51 has three suction pipes 52 at its air intake. Two of them are connected to the bag spreading suction port 34 and the bag taking suction port 28 respectively via flexible hoses. The suction end of the other one is equipped with a bag swinging negative pressure plate 27, and the bag swinging negative pressure plate 27 has several round holes arranged on it. The bag swinging negative pressure plate 27 is fixed to the upper wall of the internal component box 21 between the bag taking plate 23 and the bag spreading plate 31.

[0035] The air purifier 51 is a multi-functional device that not only purifies the air but also provides a negative pressure source for the bag-removing suction port 28, the bag-spreading suction port 34, and the bag-swinging negative pressure plate 27. The bag-swinging negative pressure plate 27 adsorbs the lower part of the garbage bag through round holes, helping to straighten the position of the garbage bag and ensuring accurate subsequent unfolding and sealing operations.

[0036] The bag-collecting plate 23 includes a bag-collecting swing arm 22, and the bag-collecting swing arm 22 is fixedly connected to the bag-collecting plate 23. The two form a gantry structure. The bag-collecting swing arm 22 includes a first telescopic rod 24, which divides the bag-collecting swing arm 22 into two sections. The extension and retraction of the bag-collecting swing arm 22 are controlled by the first telescopic rod 24. The first protective rubber sleeve 25 is provided on the outside of the first telescopic rod 24. The bottom of the bag-collecting swing arm 22 is provided with a first rotating wheel 26 that is rotatably connected to the internal component box 21.

[0037] The bag-dispensing plate 31 includes an adjusting arm 32, and the adjusting arm 32 and the bag-removing plate 23 are in a gantry structure. The adjusting arm 32 includes a second telescopic rod 37, which divides the adjusting arm 32 into two sections. The extension and retraction of the adjusting arm 32 are controlled by the second telescopic rod 37. The second telescopic rod 37 is covered with a second protective rubber sleeve 38. The bottom of the second telescopic rod 37 is provided with a second rotating wheel 33 that is rotatably connected to the internal component box 21. The extension and retraction diameter of the second telescopic rod 37 is greater than that of the first telescopic rod 24.

[0038] A heat-sealing opening 201 is provided on the side of the bag-receiving plate 23 near the bag-spreading plate 31. A plastic sealing heat plate 202 is fixedly installed inside the upper part of the heat-sealing opening 201. A bag-pushing plate 35 is fixedly installed at the highest point of the inclined surface of the bag-spreading plate 31. The bag-pushing plate 35 is made of flexible material and matches the heat-sealing opening 201.

[0039] Both the bag-spreading and rubbing column 36 and the grinding and rubbing column 29 have flexible grinding and rubbing arms 204 fixedly installed on their outer walls, and both the bag-spreading and rubbing column 36 and the grinding and rubbing column 29 have drive motors 203 installed below them to drive the bag-spreading and rubbing column 36 and the grinding and rubbing column 29 to rotate.

[0040] The pre-storage component includes a bag-holding chamber 41, the opening of which faces the bag-receiving plate 23 and the bag-spreading plate 31. The top of the interior of the bag-holding chamber 41 is arrayed with bag-hanging posts 42, and the top of the bag-hanging posts 42 has a soft barb structure.

[0041] When using it, medical support staff need to put the special garbage bags into the smart garbage bin 11 one by one. The opening of the garbage bag needs to have multiple round holes at the beginning, and a QR code should be attached to the front of the garbage bag in advance. The support staff hang the garbage bags one by one on the hanging column 42, with the side of the garbage bag with the QR code facing the side of the bag outlet 12. All unused garbage bags also need to hang down naturally. When automatic bagging is required, the second telescopic rod 37 controls the bag-spreading plate 31 to descend to the lowest position, and the first telescopic rod 24 controls the bag-retrieving plate 23 to rise to the highest position. At the same time, the camera 17 can capture the QR code on the front of the garbage bag, and the system will record the information of this garbage bag until the QR code of the next garbage bag is scanned. Driven by the drive motor 54 and the transmission belt 55, the bag-retrieving plate 23 rotates and tilts towards the bag-placement chamber 41 until the bag-retrieving suction port 28 of the bag-retrieving plate 23 presses tightly against the outermost garbage bag. At this time, the bag-retrieving plate 23 is pressed under the bag-hanging column 42. At the same time, the air purifier 51 starts working, and the air inlet of the air purifier 51 is also equipped with a powerful suction pump. The garbage bag is sucked tightly through the hose and the bag-retrieving suction port 28. Then, the drive motor 54 drives the bag-retrieving plate 23 to rotate back to the initial position. At this time, the outermost garbage bag can be pulled out from the bag-hanging column 42. The barbed bag-hanging column 42 prevents excess garbage bags from being pulled out. At this time, the lower part of the garbage bag taken out by the bag-removing plate 23 will hang on the lower bag-spreading plate 31. Through the downward suction force of the bag-swinging negative pressure plate 27, the lower part of the garbage bag can be sucked from the bag-spreading plate 31 onto the bag-swinging negative pressure plate 27, thus straightening the garbage bag. Then, the second telescopic rod 37 drives the bag-spreading plate 31 to rise to its highest position, and then the corresponding drive motor 54 drives the bag-spreading plate 31 to rotate towards the bag-removing plate 23, so that the inclined surface of the bag-spreading plate 31 is tightly attached to the lower part of the bag-removing suction port 28. At this time, the bag-spreading suction port 34 is also in a negative pressure adsorption state. The bag-taking suction port 28 and the bag-spreading suction port 34 respectively suck the two sides of the garbage bag. At the same time, the drive motor 203 drives the grinding column 29 and the bag-spreading grinding column 36 to rotate simultaneously, so that the grinding arm 204 grinds the garbage bag, causing the bag opening of the garbage bag to separate. The separated bag opening will be crushed in the bag-spreading suction port 34 and the bag-taking suction port 28 by the grinding arm 204 and the grinding column 29. Then, the bag opening of the garbage bag is completely opened by the reset of the bag-spreading plate 31. When medical staff hold the smart screen module 15 tightly, the system will automatically control the electric lock 16 to open the automatic door 14. After that, medical staff can directly throw medical waste into the garbage bag from the garbage inlet 13. Meanwhile, the air purifier 51 continues to work and constantly treats the air in the smart garbage can 11. Air purifier 51 processes indoor air, reducing odors and harmful gases, and improving the environment.

[0042] The control module 53 coordinates the operation of the entire system to achieve automated control.

[0043] The drive motor 54 and the transmission belt 55 provide stable power to ensure that the rotation of the bag-taking plate 23 and the bag-spreading plate 31 is accurate and reliable.

[0044] As the trash falls into the trash bag, camera 17 captures the appearance of the trash and records it in this QR code information; When camera 17 detects that the garbage in the garbage bag has reached two-thirds full, the system controls the bag-spreading plate 31 to descend a short distance, then controls the bag-spreading plate 31 and the bag-retrieving plate 23 to rotate simultaneously, and alerts the logistics personnel to handle the situation. The garbage bag on this side of the bag spreading plate 31 will wrinkle. Then, all the wrinkles can be pressed into the heat seal 201. Then, control the bag spreading plate 31 to rise, and push the bag opening of the garbage bag into the sealing heat plate 202 through the bag pushing plate 35 for heating and sealing.

[0045] Finally, after the logistics personnel arrive, the system controls the bag outlet 12 to open automatically, and the logistics personnel take out the sealed garbage bag.

[0046] Depending on the needs, the disinfection lamp 18 can sterilize the smart trash can 11.

[0047] The embodiments of the present invention have been described above, but the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of the present embodiments, all of which are within the protection scope of the present embodiments.
