Abstract
Description
Technical Field
[0001] This invention relates to the field of medical waste collection equipment technology, specifically to a medical waste collection device. Background Technology
[0002] A large amount of medical waste is usually generated after hospital treatment or surgery, such as medical consumable packaging, needles, or cotton swabs and gauze left after wiping wounds. This medical waste is usually divided into infectious waste, household waste and trauma waste. After treatment, it is usually necessary to put them in different trash cans to avoid cross-infection.
[0003] Currently, general household waste generated after medical treatment is usually disposed of directly in trash cans. Infectious and sharps waste, however, requires specialized storage facilities, such as medical kidney trays placed on medical carts for temporary storage. After treatment, the waste in the kidney trays is taken to a centralized waste disposal point, or traditional covered medical waste collection bins are used. While these methods achieve the separation of different types of waste, the following key issues remain: 1. Risk of cross-infection: Although the current method places both infectious and sharps waste in medical kidney trays, medical staff still need to sort the waste when putting it into the sorting point. This process can easily lead to accidental contact with bloodstains, resulting in infection.
[0004] 2. Insufficient storage space: If the bleeding of the patient being treated is too large, the amount of gauze used will be far more than one kidney dish can hold. Therefore, multiple kidney dishes will be used to store the gauze at the same time. This will undoubtedly increase the space occupied on the treatment cart workbench and also increase the difficulty of collecting the gauze after treatment.
[0005] 3. Inflexible disposal: In the inpatient department, centralized sorting and disposal points are usually set up in a fixed area, and medical staff have to go back and forth to dispose of medical waste each time, which causes inconvenience.
[0006] 4. Safety hazards of manually opening the top cover to dispose of garbage: When using medical waste collection bins with top covers, it is inevitable that bloody needles or gauze will be thrown in along the edge of the top cover, causing the top cover to be stained with blood for a long time. When opening the lid the next time, your hands will be stained with this blood, creating a safety hazard.
[0007] To address the aforementioned issues, a medical waste collection device is proposed. Summary of the Invention
[0008] To address the aforementioned problems, this invention provides a medical waste collection device. While existing methods place both infectious and sharps waste in medical kidney trays, medical staff still need to sort the waste before depositing it into the designated collection point. This process can easily lead to accidental contact with blood, causing infection. Furthermore, if a patient experiences significant bleeding, the amount of used gauze far exceeds the capacity of a single kidney tray, necessitating the use of multiple trays. This increases the space occupied on the treatment cart's workbench and complicates waste collection. Additionally, the centralized collection point is located in a fixed area, requiring medical staff to travel back and forth to dispose of medical waste, causing inconvenience.

[0018] Compared with the prior art, the present invention provides a medical waste collection device, which specifically includes the following beneficial effects: 1. Avoid cross-infection This equipment integrates three movable bins inside the outer bin to achieve waste sorting, bringing the waste sorting process forward to before and during treatment. This avoids the need to re-sort infectious and sharps waste in the traditional bend tray later, greatly reducing the risk of cross-infection.
[0019] 2. Improve space utilization The integrated solution adopted by this equipment saves floor space by exposing the most frequently used operating table surface and making reasonable use of the previously underutilized space between the treatment cart floor and the operating table to integrate the trash can. This avoids the problems of traditional curved trays being "land-consuming" and "shallow", thus improving space utilization.
[0020] 3. Increased flexibility in deployment After medical staff complete tasks such as infusion, dressing change, and bandaging, this device eliminates the need to leave the patient's bedside to search for trash cans. Simply step on the pedal to extend the outer bin, which carries three smaller trash cans. As the three smaller trash cans extend, they move upwards towards the medical staff, allowing for immediate trash sorting. This significantly increases the flexibility of waste disposal, seamlessly integrates with treatment, and forms a closed loop from operation to disposal, avoiding the fragmented process of traditional carts and separate trash processing.

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the invention.
[0027] refer to Figures 1 to 11 A medical waste collection device includes a mobile carrier, a support assembly, an outer bucket 6, a top cover 7, a horizontal mounting plate 10, a placement assembly, an operating mechanism, a sliding mechanism, a lifting mechanism, and a disinfection mechanism. The mobile carrier is equipped with a support component, and an outer bucket 6 is movably mounted on the support component. The outer bucket 6 is driven to slide by a sliding mechanism. The mobile carrier is a carrier that carries the support component. Its shape is like a common treatment cart. The support component is used to carry the movable outer bucket 6. The outer bucket 6 integrates three fan-shaped trash cans 25, which will be described later. The three fan-shaped trash cans 25 evenly divide the internal space of the outer bucket 6. A top cover 7 is movably installed on the top of the outer bin 6, and a placement component is movably installed inside the outer bin 6. Both the placement component and the top cover 7 are driven to move by a lifting mechanism. The top cover 7 is used to seal the top of the outer bin 6. The top cover 7 will flip upward and open under the drive of the lifting component, and the placement component carrying three fan-shaped trash cans 25 will extend upward to facilitate the disposal of trash by medical staff. The lifting mechanism is driven by the sliding mechanism. An operating mechanism is installed inside the mobile carrier. The operating mechanism is installed on one side of the outer barrel 6. The sliding mechanism is driven by the operating mechanism, which is the triggering and starting component of this equipment. A disinfection mechanism is installed on the other side of the outer tub 6. The disinfection mechanism is installed inside the mobile carrier and is driven by a sliding mechanism. The disinfection mechanism is used to perform disinfection once after the outer tub 6 is reset each time.
[0028] The mobile carrier includes a base plate 1, an operating platform 4, casters 2, support rods 3, handrails 5, and a horizontal mounting plate 10; The upper part of the four corners of the base plate 1 is fixedly installed with an operating platform 4 by a support rod 3, and the lower part of the four corners of the base plate 1 is movably installed with casters 2. The same handrail 5 is installed between the upper right walls of the two support rods 3 located on the right side; A horizontal mounting plate 10 is installed between the two support rods 3 on the left side, and the disinfection mechanism is installed on the horizontal mounting plate 10. The support assembly is installed on the upper left side of the base plate 1, and the operating mechanism is installed on the upper right side of the base plate 1. (Refer to...) Figure 1As shown, the base plate 1, operating table 4, casters 2, support rods 3, and handrails 5 of the mobile carrier constitute the main structure of the treatment cart. Unlike common treatment carts, this device makes reasonable use of the space between the base plate 1 and the operating table 4 in the treatment cart, integrating the operating mechanism, support components, and outer bucket 6 inside, which facilitates subsequent waste disposal operations and avoids the problem of traditional bending trays occupying space on the operating table 4.
[0029] The support assembly includes a vertical plate 14, a first guide rod 15, and a side plate 16; The upper left part of the base plate 1 is respectively equipped with the first ends of two vertical plates 14, and the front walls of the second ends of the two vertical plates 14 are respectively fixedly installed with two first guide rods 15; Side plates 16 are fixedly installed on the left and right side walls of the outer tub 6 via connecting shafts. Two first guide rods 15 located on the same side are slidably connected to the side plates 16 adjacent to them. Two vertical plates 14 limit the installation width of the outer tub 6, while the first guide rods 15 limit the installation height of the outer tub 6, leaving a certain space between the bottom wall of the outer tub 6 and the bottom plate 1. The side plates 16 on both sides of the outer tub 6 are slidably sleeved on the two first guide rods 15 adjacent to them, limiting their sliding trajectory and ensuring that they will not shift or fall off during the sliding process.
[0030] The sliding mechanism includes a first connecting rod 18, a first connecting frame 401, a convex shaft 1601, and a through groove 1801; Two first connecting frames 401 are respectively installed on the lower right side of the front wall of the control panel 4, and the first end of the first connecting rod 18 is rotatably installed in the two first connecting frames 401. A convex shaft 1601 is installed on the right wall of the side plate 16 located on the right side. A through groove 1801 is provided on the first connecting rod 18 near the cam shaft 1601, and the cam shaft 1601 and the through groove 1801 are slidably connected through each other; The side panel 16 located on the left side operates the disinfection mechanism through sliding; The two side plates 16 operate via sliding drive lifting mechanisms. Both first connecting rods 18 are driven to rotate by the operating mechanism. When the two first connecting rods 18 rotate downward under the drive of the operating mechanism, the first connecting rod 18 near the outer barrel 6 will drive the convex shaft 1601 in its through groove 1801 to slide upward. Since the convex shaft 1601 is fixed to the side plate 16 near it, the side plate 16 will drive the outer barrel 6 near it to slide forward and eventually slide out from under the operating table 4. The included angle between the first connecting rod 18 and the upper end face of the side plate 16 near it becomes larger. When the two first connecting rods 18 return to their original position, the outer barrel 6 will slide from the lower outside of the operating table 4 into the lower part of the operating table 4, without taking up space.
[0031] The operating mechanism includes a second guide rod 24, a pedal 8, a connecting block 801, a second connecting rod 9, a spring, and a second connecting frame 1802; Two second guide rods 24 are fixedly installed between the base plate 1 and the operating table 4, and both second guide rods 24 are installed on the right side of the side plate 16 located on the right side. The same connecting block 801 is slidably installed on the outer wall of the two second guide rods 24, and the connecting block 801 is movably installed between the two first connecting rods 18; Springs are installed on the outer sides of the two second guide rods 24 respectively, and the two springs are installed between the connecting block 801 and the base plate 1 respectively; A pedal 8 is fixedly mounted on the front side of the connecting block 801. Fixed shafts are respectively mounted on the front parts of the left and right side walls of the pedal 8. The first ends of second connecting rods 9 are rotatably mounted on the outer walls of the two first fixed shafts. Second connecting frames 1802 are respectively mounted on the front walls of the middle ends of the two first connecting rods 18. The second ends of the two second connecting rods 9 are rotatably mounted within the adjacent second connecting frames 1802. (Reference) Figure 5 When medical staff step on pedal 8 and cause it to slide downward, the connecting block 801, which is fixedly installed thereto, slides downward along the two second guide rods 24 and further compresses the spring. At this time, the spring provides an upward reset tendency for the connecting block 801 and pedal 8. As pedal 8 slides downward, the second connecting rods 9 on both sides begin to deflect downward, and in the process of deflecting downward, they respectively drive the two first connecting rods 18 to start rotating downward, and cause the outer bucket 6 to slide forward. When medical staff dispose of the garbage, they can stop stepping on pedal 8. At this time, the connecting block 801 and pedal 8 are lifted upward under the upward reset of the spring, and the two second connecting rods 9 deflect upward and drive the two first connecting rods 18 to rotate upward. The outer bucket 6 is reset to below the operating table 4, forming a storage.
[0032] The placement component includes a tray 26, a fan-shaped trash can 25, a slider 2601, and a chute 602; A tray 26 is slidably installed inside the outer barrel 6, and four sliders 2601 are installed at equal angles on the outer wall of the tray 26. The inner wall of the outer barrel 6 is provided with four sliding grooves 602 that cooperate with the sliders 2601. The four sliders 2601 are slidably installed in the sliding grooves 602 that are close to them. Three fan-shaped trash cans 25 are detachably installed on the upper end of the tray 26. The central angles of the three fan-shaped trash cans 25 are all equal. The three fan-shaped trash cans 25 are detachably and movablely installed inside the outer bucket 6. The bottom walls of the three fan-shaped trash cans 25 are each equipped with a positioning hemisphere, and the top wall of the tray 26 is equipped with three positioning hemisphere grooves that cooperate with the positioning hemispheres. The three positioning hemispheres can be detachably installed in the positioning hemisphere grooves that are close to them. The tray 26 is driven to rise and fall by the lifting mechanism. Under the action of the lifting mechanism (described later), the tray 26 can support the three sector-shaped trash cans 25 to move up and down inside the outer bin 6. The three positioning hemispherical grooves on the top of the tray 26 cooperate with the positioning hemispheres at the bottom of the three sector-shaped trash cans 25 to form a limit. The outer diameter of the "outer circle" formed by the three sector-shaped trash cans 25 is close to the inner diameter of the outer bin 6. The cooperation between the positioning hemispheres and the positioning hemispherical grooves can limit its rotation around the axial direction of the outer bin 6, which is convenient for corresponding with the sign (described later) and facilitates the classification and disposal of trash. The cooperation between the sliding groove on the inner wall of the outer bin 6 and the slider on the tray 26 can limit the movement trajectory of the tray 26, so that it can only move up and down without rotation. The three sector-shaped trash cans 25 correspond to infectious waste, household waste and sharps waste, respectively, which facilitates the classification and disposal of these three types of medical waste.
[0033] The lifting mechanism includes a horizontal movable plate 17, a rotating shaft 19, a first transmission wheel 20, a second transmission wheel 2001, a transmission belt 23, a threaded rod 27, a spur gear 21, and a rack plate 22. A horizontal movable plate 17 is fixedly installed between the rear ends of the two side plates 16, and the horizontal movable plate 17 is installed on the rear side of the outer barrel 6. A rotating shaft 19 is rotatably installed through the middle end of the horizontal movable plate 17. A spur gear 21 is fixedly installed at the top end of the rotating shaft 19. A rack plate 22 is installed on the lower left side of the operating table 4. The spur gear 21 and the rack plate 22 are meshed together. The lower end of the rotating shaft 19 is fixedly installed with a first transmission wheel 20, and the lower end of the outer barrel 6 is rotatably installed with a second transmission wheel 2001 through a threaded rod 27. The threaded rod 27 and the bottom wall of the outer barrel 6 are rotatably connected. The same transmission belt 23 is installed between the first transmission wheel 20 and the second transmission wheel 2001; A threaded connection is provided between the center of the threaded rod 27 and the support plate 26; Each of the three fan-shaped trash cans 25 has an arc groove 2501 installed at its center, and the threaded rod 27 is movably connected to the three arc grooves 2501. The diameter of the first transmission wheel 20 is larger than the diameter of the second transmission wheel 2001, for reference. Figure 3When the outer tub 6 slides out to the left, it will cause the horizontal movable plate 17, which is fixedly installed thereto, to slide out to the left. Simultaneously, the horizontal movable plate 17 causes the rotating shaft 19, which is rotatably mounted thereto, to slide out to the left. Since a spur gear 21 is fixedly sleeved on the upper end of the rotating shaft 19, it will cause the spur gear 21 to slide out to the left. Because the spur gear 21 is always engaged with the rack plate 22 fixedly installed at the lower end of the operating table 4 while sliding out to the left, the spur gear 21 will start to rotate and cause the rotating shaft 19 to start rotating. During the rotation of the rotating shaft 19, it will also cause the first transmission wheel 20 at the lower end to rotate. Simultaneously, the first transmission wheel 20, through the transmission belt 23, will cause the second transmission wheel 2001 to start rotating. At this time, because the diameter of the first transmission wheel 20 is larger than the diameter of the second transmission wheel 2001, the second transmission wheel 2001 will be rotated. The second transmission wheel 2001 transmits the accelerated rotational speed to the threaded rod 27, which is coaxially mounted with it, causing the threaded rod 27 to rotate at a faster speed. Since the threaded rod 27 rotates through the bottom wall of the outer bucket 6, it only rotates and does not move. While rotating, the threaded rod 27 drives the center of the tray 26, which is threaded through it. Therefore, the tray 26 can slide upward inside the outer bucket 6. As the outer bucket 6 slides out from under the operating table 4, the three fan-shaped trash cans 25 inside the outer bucket 6 extend upward out of the outer bucket 6, making it convenient for medical staff to dispose of trash easily without bending over, thus reducing their burden. During this process, the three fan-shaped trash cans 25 do not interfere with the bottom wall of the operating table 4 when sliding upward out of the outer bucket 6. Furthermore, since the arc grooves 2501 at the center of the three fan-shaped trash cans 5 are located outside the threaded rod 27, the threaded rod 27 will not interfere with the inner wall of the three arc grooves 2501.
[0034] A first mounting block 601 is installed on the upper front wall of the outer barrel 6, and a second mounting block 701 is installed on the front end of the top cover 7. The first mounting block 601 and the second mounting block 701 are hinged together. The upper end of the slider 2601 located on the front side is equipped with the first end of the push rod 28, and the push rod 28 is movably installed in the slide groove 602 adjacent to it; The second end of the top rod 28 and the lower end of the top cover 7 are detachably connected; Three identification plates, which correspond to the fan-shaped trash can 25, are installed on the upper end of the top cover 7. The first mounting block 601 and the second mounting block 701 form the hinge point between the top cover 7 and the outer can 6. (Refer to...) Figure 11As the tray 26 is lifted upwards, the four sliders 2601 are simultaneously lifted upwards. The slider 2601 closest to the hinge point lifts upwards, causing the top rod 28 fixedly installed with it to lift upwards. After being lifted upwards for a period of time, the top rod 28 will contact the bottom wall of the top cover 7 and drive the top cover 7 to flip upwards around the hinge point during the continuous lifting process. Since the top rod 28 is always located between the hinge point of the fan-shaped trash can 25 and the top cover 7, the three fan-shaped trash cans 25 will not collide with the top cover 7 during the lifting process. At the same time, the height of the top rod 28 is slightly higher than the height of the fan-shaped trash cans 25. Its function is that when the tray 26 is lifted upwards, the top rod 28 will touch the lower end surface of the top cover 7 first and open the top cover 7 before the three fan-shaped trash cans 25 slide upwards out of the outer bucket 6, thus avoiding interference.
[0035] The disinfection mechanism includes an arc-shaped shell 11, a disinfection bottle 12, a convex plate 13, and a lever 1301; An arc-shaped shell 11 is installed on the left rear part of the horizontal mounting plate 10. A disinfection bottle 12 is detachably installed inside the arc-shaped shell 11. The nozzle of the disinfection bottle 12 is installed above the top cover 7. The spray switch handle of the disinfection bottle 12 is movably installed above the horizontal mounting plate 10. The first end of the protruding plate 13 is vertically installed on the upper rear part of the side plate 16 on the left side. The second end of the protruding plate 13 is equipped with a lever 1301 on the left wall. The lever 1301 is movably installed above the horizontal mounting plate 10. The toggle lever 1301 and the spray switch handle of the disinfection bottle 12 have a detachable contact arrangement, see reference. Figure 2 As shown, when the outer bucket 6 slides out to the right under the operating table 4, the front side plate 16 simultaneously slides out to the right, causing the protruding plate 13 fixedly installed thereto to slide out to the right. At this time, the lever 1301 fixedly installed with the protruding plate 13 releases the spray switch handle of the disinfection bottle 12, and the circulating spray system in the disinfection bottle 12 will draw in the disinfectant to be sprayed next time. When the medical staff disposes of the garbage and releases the pedal 8, the outer bucket 6 returns to the left, causing the lever 1301 to slide back to the left. As 1301 slides to the left to reset, it provides trigger pressure to the spray switch handle of the disinfection bottle 12, causing the nozzle of the disinfection bottle 12 to spray disinfectant once onto the outer tank 6, providing disinfection for both the outer tank 6 and the top cover 7, further preventing cross-infection. It should be noted that the circulating spray system inside the disinfection bottle 12 is existing technology, such as the common pinch switch trigger spray, which will not be described in detail here. This device uses a lever 1301 to trigger the pinch switch, avoiding manual operation and reducing the risk of infection.
[0036] Implementation method of the present invention: When the device is in its initial state, such as Figure 1As shown, the pedal 8 is placed above the base plate 1, the outer bucket 6 is placed below the operating table 4 and slightly behind it, the three fan-shaped trash cans 25 inside the outer bucket 6 are all placed at the bottom of the outer bucket 6 and supported by the support plate 26, the top cover 7 is placed on the top wall of the outer bucket 6 and is in an isolated state, and the spray switch handle of the disinfection bottle 12 is in a pressurized state. When medical staff push the equipment to the treatment site, after the waste is generated, they step down on the pedal 8 to extend the outer bin 6 forward from the bottom of the operating table 4. During this process, the spray switch handle of the disinfection bottle 12 is reset to the ready-to-activate state and simultaneously draws up the disinfectant to be sprayed. As the outer bin 6 extends forward, the three fan-shaped waste bins 25 inside are simultaneously lifted upward along the axial direction of the outer bin 6. Just before the outer bin 6 extends out, the top rod 28 lifts the top cover 7 upward. As the three fan-shaped waste bins 25 continue to extend upward, the top cover 7 will be continuously lifted upward. Finally, when the outer bin 6 is completely extended out from under the operating table 4, the three fan-shaped waste bins 25 are completely lifted to a position close to the hands of the medical staff, and the top cover 7 is also completely flipped up, exposing the disposal openings of the three fan-shaped waste bins 25. Medical staff can promptly classify and dispose of the medical waste generated during the treatment process. After disposal, stop stepping on pedal 8. Pedal 8 returns to its original position, and the three fan-shaped trash cans 25 gradually retract into the outer can 6. Under the influence of gravity and the gradually descending top rod 8, the top cover 7 also gradually closes at the top of the outer can 6. When the outer can 6 is completely retracted below the operating table 4, the lever 1301 triggers the spray switch handle of the disinfection bottle 12. At this time, the nozzle of the disinfection bottle 12 can provide a spray disinfection operation to the reset outer can 6 and the top cover 7.
[0037] This equipment integrates three movable small bins inside the outer bin for waste sorting. This advances waste sorting to before and during treatment, avoiding the need for re-sorting infectious and sharps waste later in the traditional bend tray, significantly reducing the risk of cross-infection. The integrated design saves floor space by exposing the most frequently used operating table surface and making efficient use of the previously underutilized space between the treatment cart floor and the operating table. This avoids the space-consuming and shallow problems of traditional bend trays, improving space utilization. Furthermore, after medical staff complete procedures such as infusion, dressing changes, and bandaging, they do not need to leave the patient's bedside to search for waste bins. Simply stepping on the pedal causes the outer bin to extend simultaneously with the three small waste bins. As they extend, the three small bins move upwards towards the medical staff, allowing for immediate waste sorting. This greatly increases disposal flexibility, seamlessly integrating with treatment and forming a closed loop from operation to disposal, avoiding the fragmented process of the traditional cart and separate waste processing.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
