Description

Technical Field

[0001] This application relates to the field of medical waste disposal technology, and in particular to a medical waste treatment device that reduces exposure to sharps. Background Technology

[0002] With the rapid development of the healthcare industry and the increasing demands for hospital infection control, the generation of medical sharps waste, such as injection needles, infusion needles, suture needles, surgical blades, ampoules, and medical consumables with sharp edges, continues to rise. Because these medical wastes typically have sharp points or edges, they still pose a significant risk of puncture and cuts after disposal. Furthermore, their surfaces may be contaminated with blood, bodily fluids, pathogens, and medication residues. Improper handling can easily lead to occupational exposure for healthcare workers, cleaning staff, and medical waste transport personnel, and may also cause cross-infection. Therefore, specialized medical sharps collection containers are typically used for the centralized collection, temporary storage, and transport of discarded sharps to reduce the risk of direct exposure to the external environment and ensure the safety of the medical waste disposal process.

[0003] In existing technologies, medical sharps waste is generally collected using disposable sharps containers. Common sharps containers typically consist of a rigid plastic body, a dispensing opening, and an anti-retrieval structure. The container's puncture resistance seals the sharps, and the one-way dispensing mechanism prevents the inserted sharps from being retrieved. Some products also include a deflector, a flip-top mechanism, or a limiting baffle at the dispensing opening, allowing the sharps to fall into the container under gravity for storage. Once the sharps container reaches its preset capacity, it is sealed and transported for centralized medical waste disposal. This type of structure effectively prevents direct exposure of sharps and has become the mainstream technology for handling sharps waste in medical institutions.

[0004] However, in actual use, due to the wide variety of medical sharps, and the significant differences in their length, shape, mass distribution, and surface characteristics, when multiple sharps are mixed and placed into the sharps container, random collisions and disorderly accumulation occur between them, creating numerous irregular gaps inside the container. As a result, even if the sharps container has not yet reached its designed volume, blockages may already occur near the disposal opening, leading to decreased storage space utilization, increased container replacement frequency, and higher medical waste disposal costs. Furthermore, as the number of sharps in the container continues to increase, subsequent additions will collide, flip, and compress with existing sharps, causing some needle tips, blades, and glass sharp edges to gradually gather or lift towards the disposal opening. When healthcare workers continue to dispose of new medical waste, sharps are prone to snagging, jamming, or rebounding, not only affecting the smoothness of the disposal operation but also posing a risk of needle tips or blades accidentally approaching the disposal area, increasing the probability of occupational exposure. Summary of the Invention

[0005] This application provides a medical waste treatment device that reduces sharps exposure. The device can automatically classify and collect medical sharps, and then layer and seal the collected medical sharps, so that the medical sharps are kept in a controlled stacking state throughout the entire collection, temporary storage and transportation process. This not only reduces the probability of sharps tip exposure and re-intrusion, but also reduces the displacement of sharps caused by transportation vibration, thereby effectively reducing the risk of occupational exposure to sharps injuries during medical waste treatment and improving the safety of medical waste collection and transportation.

[0006] This application provides a medical waste treatment device that reduces sharps exposure, employing the following technical solution: A medical waste disposal device for reducing sharps exposure includes: The box body is provided with a detachable lid, and multiple sub-boxes are arranged inside the box body; The feeding component is disposed on the outside of the box body. The feeding component includes a feeding hopper and multiple discharging hoppers corresponding to each of the sub-boxes. The feeding hopper is provided with a feeding channel and a dividing grid. The dividing grid is used to block medical sharps larger than a preset size and guide the different medical sharps separated through the multiple discharging hoppers to the corresponding sub-boxes.

[0007] A partition assembly is mounted on the box lid. The partition assembly includes at least one partition plate, a clamping frame, and a pressing frame. The clamping frame is fixed to the side of the box lid facing the box body. The partition plate is detachably mounted on the clamping frame. The inner wall of the partition box is provided with multiple sets of limiting structures along the height direction. The pressing frame is detachably connected to the partition plate. The pressing frame is used to remove the partition plate from the clamping frame and install it into the partition box. The limiting structures are used to lock the partition plate at the limiting structure at the corresponding height, so as to divide the internal space of the partition box into multiple stacking layers.

[0008] By adopting the above technical solution and setting up a delivery component, medical sharps of different sizes and types are pre-screened using a separator during the delivery process and then introduced into the corresponding sorting boxes. This achieves preliminary classification of different medical sharps during the collection stage, avoids mixing and piling up of different sharps, improves the efficiency of subsequent medical waste classification and treatment, and reduces the occupational exposure risk caused by secondary contact with sharps by processing personnel. Meanwhile, the partition components can divide the interior of the box into multiple independent stacking layers, so that medical sharps can be stacked in layers after reaching the preset stacking height. This avoids rolling, bridging, and needle tip pointing upwards during free fall from a height, improving the density of sharps stacking and the utilization rate of the internal space of the box. It also reduces the probability of sharps rebounding, snagging, and accidental punctures when they are subsequently placed.

[0009] Optionally, a volume monitoring component is also included. This component is disposed within the compartment and includes a base plate, a load-bearing spring, a connecting belt, a sliding seat, and a tension spring. The base plate is tilted and rotatably disposed within the compartment. The load-bearing spring supports the base plate between the base plate and the inner wall of the compartment. The compartment has an installation chamber with a display window. The sliding seat is slidably disposed within the installation chamber and has a rotating roller. One end of the connecting belt is fixedly connected to the base plate, and the other end has a coating marking. The end of the connecting belt with the coating marking is wound around the rotating roller and fixedly connected to the inner wall of the installation chamber. When the base plate tilts to one side due to the accumulation of medical sharps within the compartment, the base plate, through the connecting belt, moves the sliding seat within the installation chamber, causing the coating marking to change with the position of the base plate, thus displaying the degree of accumulation of medical sharps within the compartment.

[0010] By adopting the above technical solution and setting up a capacity monitoring component, the accumulation status of medical sharps in the compartments is converted into color changes in the display window. By simply observing the color changes in the display window, the loading level of each compartment can be quickly determined, realizing an intuitive display of the capacity status of each compartment. This improves the convenience and accuracy of capacity judgment, reduces the time that operators spend observing near the disposal port, and avoids obstruction of further disposal or exposure of sharps due to local overfilling, further enhancing the safety of handling medical waste sharps.

[0011] Optionally, the feeding assembly further includes a cover plate, and the plurality of sub-boxes are respectively configured as a first sub-box, a second sub-box, and a third sub-box; the plurality of discharge hoppers on the feeding hopper are respectively configured as a first discharge hopper, a second discharge hopper, and a third discharge hopper; the dividing grid intercepts intact glassware and guides it into the first sub-box through the first discharge hopper; the inner bottom wall of the feeding hopper is inclined, and a drop-out opening is formed on the inner bottom wall of the feeding hopper; the cover plate covers the drop-out opening, and a screening channel is formed between the cover plate and the inner bottom wall of the feeding hopper; the height of the screening channel is set to allow surgical blades to pass through; the feeding channel communicates with the second sub-box through the screening channel; the screening channel filters out surgical blades and guides them into the second sub-box through the second discharge hopper; the third sub-box communicates with the third discharge hopper, and the third sub-box is used to collect other sharp instruments.

[0012] By adopting the above technical solution, and by setting up screening channels of different heights and multiple discharge hoppers, complete glassware, surgical blades and other medical sharps can automatically enter the corresponding bins according to their size characteristics. This achieves automatic classification and collection of various medical sharps without manual intervention, reducing collisions, breakage and cross-accumulation between different sharps. It also facilitates the subsequent adoption of targeted treatment processes and improves the efficiency of medical waste disposal.

[0013] Optionally, the first compartment is larger than the third compartment, and a plurality of deceleration strips are evenly distributed on the inner wall of the first compartment. The deceleration strips are used to slow down the falling speed of the glassware and reduce secondary breakage.

[0014] By adopting the above technical solution, and by setting deceleration bars in the first compartment, the falling glassware is buffered in multiple stages, which gradually slows down the glassware as it enters the compartment, reducing the risk of secondary breakage due to impact with the bottom of the compartment or collisions with each other, avoiding the generation of a large number of sharp glass fragments, and improving the safety of subsequent medical waste collection and treatment.

[0015] Optionally, the feeding assembly further includes a polarizing element, which includes a housing, a micro motor, a power supply unit, and a counterweight. The housing is detachably mounted on the feeding hopper. The micro motor and the power supply unit are both located inside the housing. The micro motor is electrically connected to the power supply unit. The counterweight is eccentrically fixed on the output shaft of the micro motor.

[0016] By adopting the above technical solution and setting up a polarizing element, the feeding hopper generates continuous micro-vibration during the feeding process, prompting medical sharps that are near the separator and screening channel to adjust their posture in time and continue to be conveyed forward. This reduces the occurrence of sharps jamming, bridging and blockage, improves the automatic screening efficiency and feeding continuity of medical sharps, and ensures that different medical sharps can stably enter the corresponding sorting box.

[0017] Optionally, the clamping frame is provided with multiple partition plates and multiple sets of limiting members. The multiple sets of partition plates are detachably mounted on the clamping frame through the limiting members. Each limiting member includes a limiting block and a positioning spring. The partition plates are provided with positioning grooves, which are slidably connected to the clamping frame. The clamping frame is provided with receiving grooves. One end of the limiting block is slidably mounted in the receiving groove, and the other end of the limiting block is provided with a wedge-shaped tip. The positioning spring is mounted in the receiving groove. One end of the positioning spring is fixedly connected to one end of the limiting block, and the other end of the positioning spring is fixedly connected to the inner wall of the receiving groove. The end of the limiting block opposite to the positioning spring is movably abutting against one side of the partition plate along its length.

[0018] By adopting the above technical solution, multiple sets of limiting components are set on the clamping frame, which can reliably fix multiple partition plates inside the box lid for backup storage. The corresponding partition plate can be quickly removed and installed according to the accumulation of medical sharps in the box, thereby improving the efficiency of partition plate removal and placement, preventing the spare partition plates from becoming loose during transportation and use, and improving the reliability of the partition components.

[0019] Optionally, the pressing frame includes a first mounting rod, a second mounting rod, and a pressing rod. Both the first mounting rod and the second mounting rod are slidably mounted on the box cover. The end of the first mounting rod extending into the box body is provided with a quick-release structure. The quick-release structure includes a snap-fit ​​groove at one end of the first mounting rod and an abutment portion and a support portion respectively provided on both sides of the snap-fit ​​groove. The snap-fit ​​groove is located at the end of the first mounting rod away from the pressing rod. The snap-fit ​​groove and the positioning groove are snap-fitted together. The support portion is located below the abutment portion. The abutment portion is wedge-shaped, and the support portion is semi-cylindrical. The abutment portion moves against the side of the partition plate facing the cover plate, and the support portion moves against the other side of the partition plate. When the partition plate is snap-fitted with the limiting structure, the pressing frame is pulled upward. The support portion forces the first mounting rod to swing to one side, thereby causing the snap-fit ​​groove to contact and snap-fit ​​with the positioning groove. The second mounting rod has the same features as the first mounting rod, and the first mounting rod and the second mounting rod are symmetrically arranged along the width direction of the lid. The ends of the first mounting rod and the second mounting rod located on the outside of the lid are respectively fixedly connected to the two ends of the pressing rod.

[0020] By adopting the above technical solution and setting up a pressing frame and quick-release structure, operators can directly complete the installation, pressing and disassembly of the partition plate on the outside of the box cover. The partition plate can be arranged without reaching into the box, which reduces the operator's chance of contacting sharp objects inside the box, further reduces occupational exposure risk, and improves the installation efficiency and positioning accuracy of the partition plate.

[0021] Optionally, the inner wall of the feeding hopper near the second discharge hopper is provided with a linearly gradually expanding section, and the drop outlet is located on the inner bottom wall of the expanding section; a guide plate is fixed inside the feeding hopper, and the guide plate is used to guide the sharp object to move towards the expanding section.

[0022] By adopting the above technical solution, by setting up an expansion section and a guide plate, medical sharps are guided to gradually move towards the screening channel. The expansion section is used to gradually adjust the movement posture of the medical sharps, making it easier for blade-shaped sharps such as surgical blades to enter the corresponding screening channel, reducing the phenomenon of blade lateral jamming or blockage, and improving screening efficiency and automatic classification stability.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a delivery component and utilizing separators, screening channels, and multiple discharge hoppers, medical sharps of different sizes and types are automatically sieved, allowing complete glassware, surgical blades, and other medical sharps to enter their corresponding boxes. This achieves automatic classification of medical sharps during the collection stage, avoiding the mixing and accumulation of different sharps. This not only reduces the probability of different sharps colliding, breaking, and entanglement, but also facilitates the subsequent use of corresponding sterilization, crushing, or resource recovery processes based on different sharps. It also reduces the chance of personnel coming into direct contact with sharps during secondary sorting, thereby effectively reducing occupational exposure risks. 2. By setting up a partition component, after the medical sharps are stacked to a preset height, the partition plate can be installed at the corresponding height position inside the compartment, dividing the inside of the compartment into multiple independent stacking layers. This ensures that the medical sharps subsequently added are always stacked within a low drop range, avoiding situations where sharps may roll, cross-bridge, or have needle tips or blades facing upwards due to long-distance free fall. This improves the stacking density of medical sharps and the utilization rate of the internal space of the compartment, while also reducing the risk of sharps rebounding, snagging, and accidental punctures to medical personnel during subsequent deployment.

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0033] This application discloses a medical waste treatment device that reduces exposure to sharps.

[0034] Reference Figure 1 and Figure 2 A medical waste disposal device for reducing sharps exposure includes a container 1, a delivery component 2, a partition component 3, and a volume monitoring component 4. The delivery component 2 is installed on the outer wall of the container 1. The partition component 3 and the volume monitoring component 4 are both installed inside the container 1, with the partition component 3 located above the volume monitoring component 4. The volume monitoring component 4 is installed on the inner bottom of the container 1. The container 1 serves as the carrier for storing medical sharps. The delivery component 2 provides a channel for medical sharps to enter the container 1 and can automatically classify the delivered medical sharps, allowing them to be stored separately within the container 1. The partition component 3 automatically installs a partition 31 inside the container 1 when the medical sharps accumulate to a certain level, reducing the risk of occupational exposure to sharps injuries and ensuring that the medical sharps are tightly packed within the container 1. The volume monitoring component 4 displays the real-time quantity of medical sharps inside the container 1.

[0035] Reference Figure 2 , Figure 3 and Figure 4In this embodiment, the box body 1 is a rectangular box with an open top. The box body 1 is made of high-strength plastic such as polypropylene or high-density polyethylene. An upwardly extending annular connecting wall is provided on the outer periphery of the open edge of the box body 1. A box cover 11 is provided on the open edge of the box body 1, and the box cover 11 is detachably fastened and fixed to the annular connecting wall. A stepped surface is provided inside the box body 1. Multiple sub-boxes 12 are provided inside the box body 1. The multiple sub-boxes 12 are respectively designated as a first sub-box 121, a second sub-box 122, and a third sub-box 123. An installation part is fixed on the outer periphery of the open edge of the first sub-box 121. The installation part is located on one side of the width direction of the first sub-box 121, and two sets of installation parts are symmetrically arranged along the length direction of the first sub-box 121. The first sub-box 121 is mounted inside the box body 1 via the mounting part. The first sub-box 121, the second sub-box 122, and the third sub-box 123 are arranged along the length of the box body 1. However, the overall size of the first sub-box 121 is larger than that of the second sub-box 122. The overall size of the second sub-box 122 and the third sub-box 123 are the same. In this embodiment, the overall size of the first sub-box 121 is twice that of the second sub-box 122.

[0036] In addition, a first observation window is provided on one side of the first compartment 121 in the width direction, and a second observation window is provided on the second compartment 122, a first observation window is provided on the third compartment 123, and a fourth observation window is also provided on the outer wall of the box body 1, so that the quantity of medical sharp instruments in the box body 1 can be observed in real time from the outside.

[0037] Reference Figure 2 and Figure 3 In this embodiment of the application, the feeding component 2 includes a mounting frame, a feeding hopper 21, a partition grid 23, a cover plate 24 and a polarizing element 25. A guide rail is fixed on the outer wall of one side of the box body 1 along its length. The mounting frame is provided with a snap-fit ​​part that is adapted to the guide rail. The snap-fit ​​part is slidably snapped into the guide rail. The mounting frame is fixedly connected to the guide rail by bolts. The mounting frame is fixed to the box body 1 by the guide rail.

[0038] The feeding hopper 21 is fixed on the mounting frame. The feeding hopper 21 has a feeding channel. One end of the feeding hopper 21 is set as the feeding end. A vertical plate is fixed on the feeding end. A needle separation groove is opened through the vertical plate. The inner diameter of the needle separation groove gradually expands along the length of the groove opening. A clamping blade is protruding on at least one side of the groove wall of the needle separation groove. The cutting edge of the clamping blade faces the inner space of the separation groove.

[0039] Multiple discharge hoppers 22 are fixedly installed on the feeding hopper 21. The multiple discharge hoppers 22 are respectively set as the first discharge hopper 221, the second discharge hopper 222 and the third discharge hopper 223. The box body 1 is respectively provided with a first input port, a second input port and a third input port. The first input port is connected to the first sub-box 121, the second input port is connected to the second sub-box 122 and the third input port is connected to the third sub-box 123. The first input port is connected to the feeding channel through the first discharge hopper 221, the second input port is connected to the second discharge hopper 222 and the third input port is connected to the third discharge hopper 223.

[0040] The separator 23 is fixed inside the feeding hopper 21. The separator 23 is located on the side of the first discharge hopper 221 near the second discharge hopper 222. The separator 23 is used to intercept relatively intact glassware such as ampoules in medical sharps. The intercepted glassware is fed into the first sorting box 121 through the first discharge hopper 221. Several sets of deceleration strips 1211 are evenly distributed on the inner wall of the first sorting box 121. The deceleration strips 1211 are set as thin strips. The deceleration strips 1211 are set to avoid secondary breakage during the collection of glassware, thereby reducing occupational exposure to sharps injuries.

[0041] The separator 23 includes a mounting frame and grid bars. The mounting frame is inclined and fixed inside the feeding hopper 21, and the inclined direction of the mounting frame points to the first discharge hopper 221. In this embodiment, the inclined angle of the mounting frame is less than 5°. Multiple sets of grid bars are arranged at equal intervals inside the mounting frame, and the length direction of the grid bars is parallel to the vibration direction of the polarizing element 25.

[0042] The inner bottom wall of the feeding hopper 21 is set as an inclined surface, and the inclination direction is inclined towards the box body 1 along the width direction of the feeding hopper 21. The inner side wall of the feeding hopper 21 near the second sub-box 122 is provided with a linearly gradually expanding section. A drop opening 211 is opened on the inner bottom wall of one side of the expanding section. The cover plate 24 is fixed to the inner bottom wall of the feeding hopper 21. The cover plate 24 covers the drop opening 211, and the area of ​​the cover plate 24 is larger than that of the drop opening 211. The cover plate 24 is set as a right-angled trapezoidal plate. The long side of the cover plate 24 is fixedly connected to the expanding section. The cover plate 24 is inclined at one end toward the first discharge hopper 221. A limiting groove is provided on the side of the cover plate 24 facing the inner bottom wall of the feeding hopper 21. The side of the cover plate 24 away from the inner bottom wall of the feeding hopper 21 is provided with rounded corners. The limiting groove makes a screening channel 212 formed between the cover plate 24 and the inner bottom wall of the feeding hopper 21. The drop outlet 211 is connected to the feeding channel through the screening channel 212. The height of the screening channel 212 is slightly greater than the thickness of the scalpel blade. In this embodiment, the height of the screening channel 212 is set to 0.4 mm.

[0043] Meanwhile, a guide plate 213 is fixedly provided at one end of the feeding hopper 21 near the second compartment 122. The guide plate 213 is located on the side away from the expansion section. The guide plate 213 can guide the medical sharps in the feeding hopper 21 to move towards the expansion section. At this time, with the cover plate 24, the medical sharps that have moved here can be selectively screened. Sharps such as surgical blades can enter the second compartment 122 through the drop outlet 211, while other sharps can enter the third compartment 123, which includes, but is not limited to, sharps such as needles and glass fragments.

[0044] More specifically, because the bottom wall of the feeding hopper 21 is tilted to one side, the sharp objects entering the feeding hopper 21 will naturally be offset to the tilted side. At this time, in conjunction with the height limit setting of the cover plate 24, the surgical blades can easily pass through the screening channel 212, while sharp objects such as needles cannot enter the screening channel 212 and will eventually enter the third discharging hopper 223 into the third sorting box 123.

[0045] Reference Figure 2 In this embodiment, to ensure stable discharge of medical sharps from the feeding hopper 21, a polarizing element 25 is installed on the feeding hopper 21. The polarizing element 25 is located below the feeding hopper 21 and includes a housing 251, a micro motor 252, a power supply unit 253, and a counterweight 254. The housing 251 is detachably fixed to the feeding hopper 21 by bolts. The micro motor 252 and the power supply unit 253 are both fixed inside the housing 251. The micro motor 252 is electrically connected to the power supply unit 253. A switch for turning the micro motor 252 on and off is provided on the housing 251. In this embodiment, the power supply unit 253 can be a dry power supply unit 253 or a lithium power supply unit 253. The counterweight 254 is fixed on the output end of the micro motor 252 and is shaped like a disc. The counterweight 254 and the output end of the micro motor 252 are eccentrically positioned.

[0046] Furthermore, the needle-type medical sharp instruments provided in the embodiments of this application are not limited to injection needles and infusion needles. The infusion needle is simply the needle part cut off from the infusion tubing. This is common knowledge to those skilled in the art and will not be elaborated upon here.

[0047] Reference Figure 4 and Figure 5In this embodiment, the partition assembly 3 is installed on the box cover 11. The partition assembly 3 includes a partition plate 31, a clamping frame 32, a limiting member 34, a pressing frame 33, and a reset spring. The partition plate 31 is a rectangular plate, and positioning grooves 311 are provided through both ends of the partition plate 31 in the length direction. The first sub-box 121 is provided with multiple sets of limiting structures that cooperate with the partition plate 31 at equal intervals along the vertical height direction. The limiting structure is a limiting tenon 1212. Multiple sets of limiting tenons 1212 are also provided on the same horizontal plane. In this embodiment, four sets of limiting tenons 1212 are provided on the same horizontal plane and are symmetrically arranged in pairs along the length direction of the first sub-box 121. The first sub-box 121 is provided with three sets of limiting structures at equal intervals along the vertical height direction.

[0048] In other embodiments of this implementation, an adsorption layer and a protective layer are sequentially provided on the side of the partition plate 31 facing the first compartment 121. The partition plate 31 is made of the same material as the compartment body. The adsorption layer is made of water-absorbing resin, and the protective layer is made of sponge. The adsorption layer can absorb residual liquid on medical sharps.

[0049] Reference Figure 5 and Figure 6 In this embodiment, the clamping frame 32 is fixedly mounted on the side of the box cover 11 facing the box body 1. The clamping frame 32 is slidably inserted into the positioning groove 311. A limiting member 34 is disposed on the clamping frame 32. The limiting member 34 includes a limiting block 341 and a positioning spring 342. The limiting block 341 is elongated. The clamping frame 32 has a receiving groove 321. One end of the limiting block 341 is slidably disposed in the receiving groove 321, and the other end of the limiting block 341 is a wedge-shaped tip formed by the convergence of two inclined surfaces along the vertical direction. At the same time, an anti-detachment part is fixedly provided at the end of the limiting block 341 that extends into the receiving groove 321. The positioning spring 342 is disposed in the receiving groove 321. One end of the positioning spring 342 is fixedly connected to one end of the limiting block 341, and the other end of the positioning spring 342 is fixedly connected to the inner wall of the receiving groove 321. In addition, a plug-in groove is provided on the side wall of the clamping seat on the side where the receiving groove 321 is provided. The plug-in groove is connected to the receiving groove 321. The shape of the plug-in groove is adapted to the end of the limiting block 341 that extends into the receiving groove 321. The limiting block 341 can be installed in the receiving groove 321 through the provided plug-in groove.

[0050] In this embodiment, multiple sets of clamping frames 32 are provided on the box cover 11. Specifically, two sets of clamping frames 32 are provided above each box 12, and the two sets of clamping frames 32 are symmetrically arranged along the width direction of the box cover 11. Multiple sets of clamping frames 32 are equally spaced along the vertical direction, and are symmetrically arranged in pairs along the width direction of the clamping frames 32.

[0051] The pressing frame 33 includes a first mounting rod 331, a second mounting rod 332, and a pressing rod 333. One end of the first mounting rod 331 is slidably inserted into the cover 11. A clearance groove 322 is provided through the clamping frame 32. The end of the first mounting rod 331 that extends into the box body 1 is slidably connected to the clearance groove 322. The clearance groove 322 is larger than the cross-sectional area of ​​the first mounting rod 331. At the same time, a quick-release structure is also provided on the end of the first mounting rod 331 that extends into the box body 1. The quick-release structure includes a snap-fit ​​groove 3311 opened on the first mounting rod 331 and an abutment part 3312 and a support part 3313 respectively fixed on both sides of the snap-fit ​​groove 3311. The support part 3313 is located directly below the abutment part 3312. The abutment part 3312 is set as a wedge-shaped block, while the support part 3313 is set as a semi-cylindrical shape.

[0052] The first mounting rod 331 is also fixedly embedded with a long strip of elastic inner lining. The inner lining can be made of a spring rod. The first mounting rod 331 and the second mounting rod 332 have the same features. The first mounting rod 331 and the second mounting rod 332 are symmetrically arranged along the width direction of the box cover 11. The end of the first mounting rod 331 away from the box body 1 is fixedly connected to one end of the pressing rod 333. The other end of the pressing rod 333 is fixedly connected to one end of the second mounting rod 332. The other end of the second mounting rod 332 slides through the box cover 11. The first mounting rod 331, the second mounting rod 332 and the pressing rod 333 are combined to form a "door" shaped frame.

[0053] There are two sets of reset springs. The two sets of reset springs are respectively sleeved on the first mounting rod 331 and the second mounting rod 332. One end of the reset spring is fixedly connected to the cover 11, and the other end of the reset spring is fixedly connected to one end of the pressing rod 333.

[0054] In this embodiment, a set of isolation components is respectively provided above the first compartment 121, the second compartment 122, and the third compartment 123. This is used to lay the partition plate 31 after the medical sharps in the corresponding compartment 12 have accumulated to a certain extent. As waste continues to accumulate inside the compartment 1, the risk of exposure of the medical sharps inside the compartment 1 will also increase significantly. The partition plate 31 can divide the original large volume free stacking space into multiple thinner restricted stacking spaces, so that the thickness of each layer of waste stacking is always limited, thereby reducing the probability of sharps forming a state with the sharp points facing upwards and mutually supporting each other to form a through stacking structure; at the same time, it reduces the amplitude of sharps rearrangement and displacement during transportation vibration, thereby reducing the risk of sharps exposure and improving the safety of medical waste temporary storage and transportation.

[0055] Taking the first compartment 121 as an example, the pressing frame 33 can actively lay the partition plate 31 as waste increases. Specifically, by pulling the pressing frame 33 upward, the quick-release structure on the pressing frame 33 engages with the positioning groove 311 on the partition plate 31. Then, by pressing the pressing frame 33 downward, the limiting member 34 on the clamping frame 32 is forced to contact and limit the partition plate 31. The partition plate 31 located at the bottom of the clamping plate moves into the first compartment 121 along with the pressing frame 33. Move the part until it is pressed down to the bottom; during this process, if it is the first time installing the partition plate 31, the partition plate 31 will pass through three sets of limiting protrusions 1212 in sequence during the pressing process, and three 'click' sounds will be heard. At this point, the limiting plate and the limiting protrusions 1212 at the corresponding positions are in a limiting engagement to fix the partition plate 31; then, pull the pressing frame 33 upward, and the pressing frame 33 will be tilted to one side under the action of the supporting part 3313, so that the quick-installation structure contacts the clamping of the partition plate 31.

[0056] Furthermore, referring to Figure 7 In this embodiment of the application, each of the first compartment 121, the second compartment 122 and the third compartment 123 is provided with a set of capacity monitoring components 4. The capacity monitoring components 4 include a base plate 41, a bearing spring 42, a connecting belt 43, a sliding seat 44 and a tension spring 45. Taking the first compartment 121 as an example, the base plate 41 is set as a rectangular plate. The overall size of the base plate 41 is slightly smaller than the inner cavity of the first compartment 121. A rotating shaft is fixed on one side of the base plate 41 in the length direction. The base plate 41 is tilted and rotated on the inner bottom wall of the first compartment 121 through the rotating shaft.

[0057] The load-bearing spring 42 is disposed between the base plate 41 and the inner bottom wall of the first sub-box 121. One end of the load-bearing spring 42 is fixedly connected to the base plate 41, and the other end of the load-bearing spring 42 is fixedly connected to the inner bottom wall of the first sub-box 121.

[0058] A limiting cover is fixedly provided on the inner wall of the first compartment 121, and an installation chamber 13 is fixedly provided on the outer wall of the first compartment 121. Both the limiting cover and the installation chamber 13 are located on the side of the base plate 41 away from the rotating shaft. One end of the connecting belt 43 is fixedly connected to the end of the base plate 41 away from the rotating shaft, and the other end of the connecting belt 43 passes through the limiting cover and extends into the installation chamber 13. The sliding seat 44 is slidably disposed in the installation chamber 13. A rotating roller 441 is rotatably mounted on the sliding seat 44. One end of the connecting belt 43 extending into the installation chamber 13 is wrapped around the rotating roller 441, and the other end of the connecting belt 43 extending into the installation chamber 13 is fixedly disposed on the inner wall of the installation chamber 13.

[0059] A coating mark 431 is provided at the end of the connecting strap 43 away from the base plate 41. The coating mark 431 is a three-color coating, with the three colors being red, yellow, and green in sequence. That is, the red coating is provided at the end of the connecting strap 43 that extends into the mounting compartment 13. A display window 131 is provided on the mounting compartment 13. In the initial state, the display window 131 can fully display the three-color coating at one end of the connecting strap 43. As the amount of medical sharps accumulated in the first compartment 121 increases, the coating displayed in the display window 131 will gradually decrease until the amount of accumulated medical sharps in the first compartment 121 reaches three-quarters, and only the red coating is displayed in the display window 131.

[0060] When the first partition plate 31 is installed, only the yellow and red coatings are visible in the display window 131; when the second partition plate 31 is installed, only the red coating is visible in the display window 131; when only the red coating is visible at the top of the display window 131, it means that the medical sharps in the first compartment 121 has reached the prescribed stacking amount, and at this time the third partition plate 31 is installed to seal the first compartment 121.

[0061] The tension spring 45 is mounted on the sliding seat 44. One end of the tension spring 45 is fixedly connected to the sliding seat 44, and the other end of the tension spring 45 is fixedly connected to the bottom wall of the mounting compartment 13. In the initial state, the tension spring 45 is in a contracted state.

[0062] In addition, since the first sub-box 121, the second sub-box 122 and the third sub-box 123 are all installed inside the box body 1, the box body 1 is provided with a clearance slot for accommodating the installation compartment 13. The clearance slot is provided in three sets according to the arrangement of the first sub-box 121, the second sub-box 122 and the third sub-box 123, and the clearance slot is also provided with a fifth observation window.

[0063] More specifically, as waste continues to accumulate inside the box 1, the weight borne by the base plate 41 will increase accordingly. The bearing spring 42 will be gradually compressed, and one end of the base plate 41 will swing downward, thereby pulling the connecting belt 43 to drive the sliding seat 44 to slide upward. The corresponding coating mark 431 in the display window 131 will change, thus displaying the degree of accumulation of medical sharps in the first sub-box 121 in real time.

[0064] Furthermore, once a certain number of sub-boxes 12 inside the box 1 have reached the specified stacking level, it is only necessary to open the box cover 11 and replace the sub-box 12 individually. At the same time, when the specified stacking level is reached in the sub-box 12, the bearing spring 42 is not in the ultimate compression state, and there is still an angle between the bottom plate 41 and the bottom wall of the sub-box 12. Since this may not be immediately noticeable during actual use, it is necessary to set up installation redundancy to avoid the third partition plate 31 being unable to be installed smoothly.

[0065] The implementation principle of the medical waste treatment device for reducing sharps exposure in this application embodiment is as follows: During use, medical staff put medical sharps into the feeding hopper 21. The medical sharps first slide to one side along the inclined inner bottom wall of the feeding hopper 21 under the action of gravity, and then further concentrate in the screening area under the guidance of the guide plate 213.

[0066] Among them, intact glassware such as ampoules, due to their large overall size, are blocked by the partition grid 23 and enter the first sorting box 121 through the first discharge hopper 221 for separate collection; medical sharps after entering the screening area continue to slide along the surface of the cover plate 24. Since a screening channel 212 with a height slightly greater than the thickness of the scalpel blade is formed between the cover plate 24 and the bottom wall of the feed hopper 21, scalpel blades with smaller thickness and thinner shape can pass through the screening channel 212 and enter the second sorting box 122 through the drop outlet 211; medical sharps such as needles, syringe needle cores, and glass fragments that cannot enter the screening channel 212 continue to slide along the cover plate 24 and enter the third sorting box 123 through the third discharge hopper 223, thereby realizing the automatic classification and collection of different types of medical sharps.

[0067] At the same time, the polarizing element 25 drives the micro motor 252 to drive the eccentric counterweight 254 to rotate continuously, causing the feeding hopper 21 to vibrate slightly. On the one hand, this reduces the overlap, jamming and bridging between medical sharps, and on the other hand, it promotes the continuous flow of medical sharps to each discharge hopper 22, improving the stability and continuity of the sorting and feeding process.

[0068] As medical sharps accumulate in each compartment 12, once the operator observes that the medical sharps in the corresponding compartment 12 have reached the predetermined stacking height, the corresponding partition plate 31 can be installed using the pressing frame 33. During installation, the pressing frame 33 is quickly connected to the partition plate 31 and then pressed down. The partition plate 31 enters the compartment 12 along the clamping frame 32, passing over the limiting protrusions 1212 set at different heights in sequence during the pressing process. The limiting block 341 automatically resets under the action of the positioning spring 342, so that the partition plate 31 is reliably locked at the corresponding height position, thereby dividing the original continuous stacking space into multiple independent stacking layers.

[0069] Because the stacking thickness of each layer of medical sharps is limited, it is difficult for medical sharps to be flipped, overlapped, or to form a through-stack structure with the tips facing upwards in a large free space. At the same time, the mutual disturbance between the layers of medical sharps during transportation vibration is significantly reduced, thereby reducing the probability of medical sharps rearranging, protruding, or piercing the waste in the upper layers, and reducing the risk of occupational exposure to sharps injuries during subsequent handling and transportation.

[0070] In addition, the adsorption layer on the partition plate 31 can adsorb residual liquid from medical sharps, reducing liquid accumulation; the protective layer provides a certain buffer for medical sharps, reducing the possibility of medical waste such as glassware breaking again, and further improving the safety of sealing.

[0071] As medical sharps are continuously stacked, the weight borne by the base plate 41 gradually increases, and the load-bearing spring 42 gradually compresses, causing the base plate 41 to tilt and rotate around the pivot. This tilts and rotates the base plate 41, which in turn drives the sliding seat 44 to move synchronously within the mounting compartment 13 via the connecting belt 43. The coating markings 431 on the connecting belt 43 gradually change position relative to the display window 131 as the sliding seat 44 moves, causing the display window 131 to sequentially display green, yellow, and red areas, thus visually reflecting the real-time stacking degree of medical sharps in each compartment 12.

[0072] When the medical sharps accumulate to the predetermined capacity, only the red warning area remains in the display window 131, prompting the operator to promptly install the last layer of separator 31 and stop adding more medical sharps, thus completing the sealing of the corresponding compartment 12 and avoiding the risk of medical sharps being exposed or squeezed and punctured due to overloading.

[0073] Therefore, this application achieves automatic sorting and collection of medical sharps through delivery component 2, achieves layered and sealed storage of medical sharps through partition component 3, and achieves real-time feedback of stacking status through capacity monitoring component 4. This ensures that medical sharps are kept in a controlled stacking state throughout the entire collection, temporary storage and transportation process. This not only reduces the probability of sharps tip exposure and re-intrusion, but also reduces sharps displacement caused by transportation vibration. As a result, it effectively reduces the risk of occupational exposure to sharps injuries during medical waste treatment and improves the safety of medical waste collection and transportation.

[0074] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
