Description

Technical Field

[0001] This invention relates to the field of trash can technology, and more specifically to an isolated medical waste bin. Background Technology

[0002] Medical waste bins are specialized containers used in medical institutions to collect and temporarily store medical contaminants. Their core function is to safely contain potentially infectious, toxic, or other hazardous waste, preventing secondary contamination of medical staff, patients, and the environment. Common medical waste bins typically feature a foot-operated opening mechanism for hands-free operation. Furthermore, to meet the need for categorized storage of medical contaminants, some bins have multiple independent collection bag supports or compartments to achieve initial separation of different categories of contaminants, such as infectious, pathological, and traumatic substances. This design is a crucial component of the medical infection control system, aiming to create a basic physical barrier.

[0003] Patent CN219688210U discloses a trash can for use in hospital oncology departments, comprising a trash can body, a foot pedal, a limiting device, and an isolation device. The trash can body has a hollow interior, with a cover plate inserted at the top. A tumor-specific trash bag is placed inside the trash can body. A foot pedal is located on one side of the trash can body, and a groove is provided on the inner wall of the trash can body. An isolation device is installed inside the trash can body, which works in conjunction with a sealing rod. This trash can for use in hospital oncology departments not only prevents odors from spreading but also eliminates the need for nursing staff to touch the A or B bags of the tumor-specific trash bag, thus ensuring the hygiene of the nursing staff's hands.

[0004] The problems with the aforementioned existing technologies are as follows: Traditional flip-top structures, when opened, may disturb existing contaminants, causing splashing of contaminants or liquids and posing an exposure risk. Furthermore, common multi-layered or compartmentalized designs often only provide simple spatial divisions; when contaminants are disposed of, newly added contaminants may directly impact or come into contact with existing contaminants, failing to achieve effective dynamic isolation. All of these issues may weaken the protective effect of the trash can and increase the risk of cross-infection and occupational exposure.

[0005] Therefore, an improved solution is needed. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention proposes an isolated medical waste bin to solve the technical problems of traditional flip-top designs that easily lead to contaminant splashing when opened and the inability of the isolation compartments to open and close in conjunction for effective isolation.

[0007] An isolated medical waste bin includes: The trash can itself, the isolation compartment, and the storage compartment; The upper side of the trash can body is provided with a screw-on lid, and the lower side of the trash can body is provided with a pedal. The pedal is connected to a sliding component via a lever. The sliding component is connected to the lid. The sliding component can convert the force of the lever's pitching rotation into a horizontal rotational force to control the opening and closing of the lid. The isolation compartments are multiple and are located inside the trash can body. Each isolation compartment has a cover at the bottom, and the cover is connected to the lever via a linkage mechanism to control its opening and closing. There are multiple storage compartments, each located below the isolation compartment.

[0008] Optionally, one end of the lever is connected to the pedal, the sliding assembly includes a sliding part and a sliding link, the sliding part is connected to the bucket lid through a connecting handle, the sliding link abuts between the sliding part and the other end of the lever, and the sliding link causes the sliding part to rotate by sliding in the vertical direction.

[0009] Optionally, a sliding groove is provided on the lower side of the sliding part, the sliding groove is spiral-shaped, and the sliding connecting rod abuts in the sliding groove.

[0010] Optionally, a fixing block is provided on the body of the trash can, a fixing shaft is provided on the fixing block, the connecting handle is rotatably disposed on the fixing shaft, and a limiting part is also provided on the fixing block, the limiting part abutting against the connecting handle to limit the initial closed position of the lid.

[0011] Optionally, a plurality of disinfection lamps are provided on the underside of the bucket lid, and a control button is provided between the connecting handle and the limiting part. When the control button abuts against the limiting part, the disinfection lamps are turned on.

[0012] Optionally, the trash can body is provided with a first partition and a second partition. The first partition is provided with a plurality of disposal openings, and the second partition is provided with a plurality of storage openings corresponding to the disposal openings. The isolation compartment is located below the disposal openings, and the storage compartment is located below the storage openings.

[0013] Optionally, each of the isolation compartments is hinged to a compartment cover on its lower side. Each compartment cover is connected to the lever via a linkage mechanism to adjust its opening and closing state. The linkage mechanism includes a main rod and a first connecting rod. The main rod is vertically slidably disposed within the body of the trash can. There are multiple first connecting rods, and each first connecting rod is hinged at both ends to the compartment cover and the main rod, respectively. When the main rod slides up and down, it drives the compartment cover to rotate through the first connecting rod.

[0014] Optionally, the linkage mechanism further includes a second link and a third link. The two ends of the second link are respectively hinged to the bottom end of the main rod and one end of the third link, and the other end of the third link is hinged to the lever. When the lever rotates, it drives the main rod to slide up and down through the second link and the third link.

[0015] Optionally, a groove is provided in the middle of the second connecting rod, and a fulcrum shaft matching the groove is provided on the trash can body, so that the second connecting rod can rotate and slide around the fulcrum shaft.

[0016] Optionally, the outer wall of the trash can body is provided with multiple movable doors, and the storage compartment can be removed when the movable doors are in the open state.

[0017] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. The screw-on lid, controlled by a pedal and lever, allows for horizontal rotational opening, effectively reducing the risk of germ splashing during opening and facilitating the disposal of medical contaminants from various angles. The vertically aligned design of multiple isolation and storage compartments enables the categorized temporary and final storage of contaminants. Furthermore, the temporary storage and transfer of contaminants are linked by levers and linkage mechanisms, creating physical isolation between disposal and storage, further reducing direct or indirect contact between personnel and contaminants, and effectively improving the management of medical contaminants.

[0018] 2. In its specific structure, the pedal, through levers, sliding linkages, and a sliding section, smoothly converts the stepping force into the opening action of the lid, making operation effortless and reliable. The internal linkage mechanism (main rod, first linkage, etc.) ensures that the pedal action synchronously controls the opening and closing of the isolation chamber lid, keeping the storage chamber isolated during contaminant release, and allowing contaminants to safely fall into the storage chamber only after the pedal is released. The side wall sliding door facilitates the removal and cleaning of the storage chamber.

[0019] 3. The lid is equipped with a disinfection lamp. When the lid is closed, the limiter automatically triggers the control button to turn on the disinfection lamp, achieving immediate sterilization. The entire mechanical linkage and additional functional design realizes a safe closed loop for the entire process of dispensing, isolating, disinfecting, and cleaning within a compact space.

[0023] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.

[0025] Please see the appendix Figure 1 and 3An isolating medical waste bin includes: a bin body 1, an isolation compartment 104, and a storage compartment 106; the bin body 1 has a screw-on lid 101 on its upper side and a pedal 201 on its lower side. The pedal 201 is connected to a sliding component via a lever 202. The sliding component is connected to the lid 101 and can convert the pitching force of the lever 202 into a horizontal rotational force to control the opening and closing of the lid 101; there are multiple isolation compartments 104 disposed inside the bin body 1, and each isolation compartment 104 has a cover 1041 at its bottom. The cover 1041 is connected to the lever 202 via a linkage mechanism to control its opening and closing; there are multiple storage compartments 106 disposed below the isolation compartments 104.

[0026] The screw-on lid 101, controlled by the pedal 201, enables contactless opening and closing, avoiding the possibility of liquids or solids carrying pathogens splashing out of the trash can when the lid of a traditional flip-top trash can is opened. This effectively reduces direct contact between medical staff and contaminants, lowering the risk of cross-infection. The screw-on lid 101 also allows for convenient trash disposal from all directions. The corresponding arrangement of multiple isolation compartments 104 and storage compartments 106 allows for the categorized storage and isolation of medical contaminants, preventing the spread of contamination from mixing different contaminants and facilitating subsequent processing. The layered isolation design of the trash can ensures that contaminants first enter the isolation compartment 104 and then transfer to the storage compartment 106, rather than directly entering the storage compartment 106. This reduces direct contact between personnel and contaminants and prevents the potential for disturbance and splashing of pathogens when contaminants are discarded into the trash can. The overall structure is compact, balancing ease of operation and isolation effectiveness, making it suitable for high-hygiene environments such as hospitals, significantly improving the safety and hygiene of medical contaminant management.

[0027] In this embodiment, please refer to the appendix. Figure 7 One end of lever 202 is connected to pedal 201. The sliding assembly includes a sliding part 204 and a sliding link 203. The sliding part 204 is connected to bucket lid 101 through a connecting handle. The sliding link 203 abuts between the sliding part 204 and the other end of lever 202. The sliding link 203 causes the sliding part 204 to rotate by sliding in the vertical direction.

[0028] The pedal 201 transmits force through the lever 202, pushing the sliding linkage 203 to slide vertically, which in turn drives the sliding part 204 to rotate, ultimately controlling the opening of the lid 101. The mechanical linkage design between the lever 202 and the sliding component ensures a smooth and reliable opening and closing process for the lid 101. This structure simplifies the operation; users only need to lightly press the pedal 201 to open and close the lid, making it effortless and efficient.

[0029] In optional implementations, please refer to the appendix. Figure 4 and7 A sliding groove 2041 is provided on the lower side of the sliding part 204. The sliding groove 2041 is spiral-shaped, and the sliding connecting rod 203 abuts in the sliding groove 2041.

[0030] The sliding groove 2041 on the lower side of the sliding part 204 has a spiral upward tendency. In the initial state, the sliding connecting rod 203 abuts against the lower end of the sliding groove 2041. As the sliding connecting rod 203 moves upward, the sliding groove 2041 is compressed, which in turn drives the sliding part 204 to rotate, ultimately opening the lid 101. This design efficiently and smoothly converts the vertical stepping force of the pedal 201 into the rotational motion of the sliding part 204, effectively realizing the function of opening or closing the lid 101, making the opening process smooth and effortless. In some possible cases, the sliding groove 2041 can also be a spirally rising retaining strip, and the sliding connecting rod 203 is provided with a retaining groove that matches the retaining strip to realize the function of opening the lid 101. Under normal circumstances, when the pedal 201 is not under force, the lid 101 is in the closed state; when the pedal 201 is under force, the lid 101 is open.

[0031] For details, please refer to the appendix. Figure 7 The trash can body 1 is provided with a fixing block 205, a fixing shaft 206 is provided on the fixing block 205, the connecting handle is rotatably disposed on the fixing shaft 206, and a limiting part 207 is also provided on the fixing block 205. The limiting part 207 abuts against the connecting handle to limit the initial closed position of the can lid 101.

[0032] The fixing block 205 and the fixing shaft 206 provide a stable fulcrum for the connecting handle, ensuring the balance of the lid 101 during rotation. The limiting part 207 restricts the initial closed position of the lid 101 by abutting against the connecting handle, and also prevents the lid 101 from being accidentally opened due to accidental collisions, vibrations, or excessive rotation during closing, thus enhancing sealing and safety and ensuring that pollutants and odors do not leak out. In general, a torsion spring is provided at the fixing shaft 206, abutting between the connecting handle and the fixing block 205, allowing the pedal 201 to keep the lid 101 closed when no force is applied, or to return it from the open state to the closed state. Generally, the rotation center of the sliding groove 2041 is the fixing shaft 206.

[0033] In other implementations, please refer to the appendix. Figure 4-6 Multiple disinfection lamps 301 are provided on the underside of the lid 101. A control button 302 is provided between the connecting handle and the limiting part 207. When the control button 302 abuts against the limiting part 207, the disinfection lamps 301 are turned on.

[0034] The disinfection lamp 301 on the underside of the lid 101 is automatically triggered by the control button 302 on the connecting handle. When the lid 101 is opened, the control button 302 loses contact with the connecting handle and immediately stops working. When the lid 101 is closed, the connecting handle contacts the control button 302, immediately sterilizing the interior space with ultraviolet light, effectively inactivating pathogenic microorganisms and improving the level of hygiene protection. This design achieves simultaneous operation and disinfection, eliminating the need for additional steps, simplifying the process and strengthening infection control. In some possible cases, the lid 101 has a cavity, a disinfectant inlet 303, and multiple spray nozzles 304 on the underside of the lid 101 to spray disinfectant. The cavity inside the lid 101 can be replenished with disinfectant through the disinfectant inlet 303, and the spray nozzles 304 on the underside automatically or manually spray when contaminants are added, forming a disinfectant coating layer that directly sterilizes the surface of the contaminants or the isolation chamber 104 itself. This further reduces the risk of biological hazards, keeps the environment inside the barrel clean, reduces odor generation, and extends the cleaning cycle.

[0035] In yet another embodiment, please refer to the appendix. Figure 3 The trash can body 1 is provided with a first partition 103 and a second partition 105. The first partition 103 is provided with multiple disposal ports 1031, and the second partition 105 is provided with multiple storage ports 1051 corresponding to the disposal ports 1031. The isolation compartment 104 is located below the disposal ports 1031, and the storage compartment 106 is located below the storage ports 1051.

[0036] The first partition 103 and the second partition 105 provide double-layer isolation for the release and storage of contaminants. The release port 1031 and the storage port 1051 correspond to the isolation chamber 104 and the storage chamber 106, respectively, allowing contaminants to be temporarily stored in the isolation chamber 104 after release and then orderly fall into the storage chamber 106, thus avoiding cross-contamination. This structure enhances the airtight management of medical contaminants, while also facilitating the differentiation of different types of contaminants and improving treatment efficiency. Where possible, both the first partition 103 and the second partition 105 are equipped with drainage ramps guiding the contaminants to the release port 1031 and the storage port 1051, ensuring that contaminants can smoothly enter the isolation chamber 104 or the storage chamber 106.

[0037] For further optimized implementations, please refer to the appendix. Figure 8 Each isolation compartment 104 has a cover 1041 hinged to its lower side. Each cover 1041 is connected to a lever 202 via a linkage mechanism to adjust its opening and closing state. The linkage mechanism includes a main rod 401 and a first connecting rod 402. The main rod 401 is vertically slidably disposed inside the trash can body 1. There are multiple first connecting rods 402. Each first connecting rod 402 is hinged to the cover 1041 and the main rod 401 at both ends. When the main rod 401 slides up and down, it drives the cover 1041 to rotate through the first connecting rod 402.

[0038] Please see the appendix Figure 3 and 8 The cover 1041 on the lower side of the isolation chamber 104 is linked to the lever 202 via a linkage mechanism. This allows the force of the main rod 401 sliding up and down to be converted into the force of the cover 1041 rotating via the first linkage 402, thus causing all covers 1041 to open or close synchronously. When the pedal 201 is under force, the cover 1041 is closed, and the bucket lid 101 is open, ensuring that when medical contaminants are thrown into the isolation chamber 104, the isolation chamber 104 is closed and isolated from the storage chamber 106, preventing contaminant exposure. When the pedal 201 is not under force, the main rod 401 slides vertically and, through the first linkage 402, reopens the cover 1041, allowing contaminants to smoothly enter the storage chamber 106 through the storage opening 1051. This design ensures effective isolation, reduces odor emission and contaminant diffusion, and the mechanical linkage improves operational consistency. Generally, the main rod 401 is located in the center of the trash can body 1, and the isolation compartment 104 is arranged around the main rod 401. The hinge position of the compartment cover 1041 should also facilitate the rotation of the compartment cover 1041 driven by the first connecting rod 402. The opening angle of the isolation compartment 104 can also be set to a certain extent so that the compartment cover 1041 can be completely closed with the opening.

[0039] For details, please refer to the appendix. Figure 8-9 The linkage mechanism also includes a second link 403 and a third link 404. The two ends of the second link 403 are respectively hinged to the bottom end of the main rod 401 and one end of the third link 404. The other end of the third link 404 is hinged to the lever 202. When the lever 202 rotates, it drives the main rod 401 to slide up and down through the second link 403 and the third link 404.

[0040] The second link 403 and the third link 404 transmit the motion of the lever 202 to the main rod 401, enabling the main rod 401 to slide up and down.

[0041] Further, please refer to the appendix. Figure 8 The second link 403 has a groove in the middle, and the trash can body 1 has a fulcrum shaft that matches the groove. The second link 403 can rotate and slide around the fulcrum shaft.

[0042] When the groove in the middle of the second link 403 rotates and slides around the fulcrum axis, it can effectively transmit the pitching force of the lever 202 to the main rod 401. When the lever 202 drives the third link 404, which is hinged to it, to move upward, the end of the second link 403 that is hinged to the third link 404 also moves upward and rotates and slides around the fulcrum axis, while the end of the second link 403 that is hinged to the main rod 401 moves downward.

[0043] Further, please refer to the appendix. Figure 2 The outer wall of the trash can body 1 has multiple movable doors 102. When the movable doors 102 are open, the storage compartment 106 can be taken out.

[0044] The movable door 102 on the outer wall of the trash can facilitates the removal and replacement of the storage compartment 106 without opening the main lid 101 or accessing the internal structure, simplifying the cleaning process and reducing the risk of workers being exposed to contaminants. The movable door 102 maintains a complete seal when closed, preserving the trash can's clean appearance and hygienic safety.

[0045] The working process of this embodiment is as follows: Please refer to the appendix. Figure 1-9 Initially, the lid 101 is closed and sealed, while the lid 1041 below the isolation chamber 104 is open. When medical personnel need to dispose of medical contaminants, they gently press the pedal 201. The pedal 201 drives the sliding linkage 203 vertically via the lever 202. The sliding groove 2041 on the lower side of the sliding part 204 is subjected to force, converting the vertical sliding force of the sliding linkage 203 into rotational force, thereby smoothly opening the lid 101. Simultaneously, the movement of the lever 202 is transmitted through the second linkage 403 and the third linkage 404, causing the vertical main rod 401 to slide downwards. This, in turn, synchronously closes the lids 1041 of all isolation chambers 104 via multiple first linkages 402, ensuring that the storage chamber 106 below is isolated.

[0046] The contaminants fall into the corresponding isolation chamber 104 through the inlet 1031 of the first partition 103. After releasing the pedal 201, the lever 202 returns to its original position under the action of the reset mechanism (such as a torsion spring), driving the sliding assembly to rotate and close the lid 101. At the moment the lid 101 closes, its connecting handle presses the control button 302, automatically turning on the disinfection lamp 301 on the underside of the lid 101 to continuously sterilize the interior with ultraviolet light; if equipped with a spray system, disinfectant can also be sprayed simultaneously or as needed. At the same time, the main rod 401 slides upward, reopening the lids 1041 of all isolation chambers 104 through the linkage mechanism, allowing the temporarily stored contaminants to fall into the corresponding storage chamber 106 below, completing a safe transfer.

[0047] When the storage compartment 106 needs to be cleaned, the corresponding movable door 102 on the outer wall of the trash can can be opened directly to remove the entire storage compartment 106 for further processing, thus maximizing operational safety and hygiene.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
