Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and specifically to a medical waste recycling and processing device. Background Technology

[0002] Disposable syringes, widely used consumables in the medical field, become medical waste after medication is administered. This type of waste poses a dual risk: the needles are sharp instruments, and improper storage can easily injure operators or those handling the waste; furthermore, residual medication inside the syringe may contain active ingredients, and the needle surface may be contaminated with bacteria, viruses, and other pathogens from the patient's bodily fluids. If effective isolation and containment are not achieved during temporary storage, it can not only cause environmental pollution but also potentially lead to cross-infection among medical staff, cleaning personnel, and waste transport workers, creating a public health safety hazard.

[0003] Current methods for temporarily storing disposable syringes after use in the healthcare system are generally flawed. Traditional recycling containers can only achieve simple storage and cannot physically separate the needle from the syringe, resulting in a persistent risk of sharps exposure. Furthermore, there is a lack of mechanisms for sealing off residual medication, allowing for potential environmental contamination from evaporation or leakage. More importantly, existing technologies fail to address the spread of pathogens on the needle surface, making secondary contamination highly likely during centralized transport. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a medical waste recycling and processing device to solve the technical problem of how to avoid cross-infection during the temporary storage of syringes after use.

[0005] The technical solution adopted in this invention is: a medical waste recycling and processing device, comprising: Treatment chamber, moving chamber, pressing mechanism, and thermopressing mechanism; The treatment chamber is vertically arranged and has a delivery port at the top, allowing the syringe to be vertically inserted into the treatment chamber. The movable chamber is horizontally arranged and has one end connected to the treatment chamber. The cross-section of the movable chamber includes a body area, a push handle area, and a rolled edge area that are sequentially matched with the syringe body, syringe push handle, and syringe barrel rolled edge. The pressure-removing mechanism is located in the treatment cavity corresponding to the syringe barrel area. The pressure-removing mechanism can hold the syringe tightly and drive the syringe to move up and down. The pressure-removing mechanism can also slide the syringe along the moving cavity. The thermo-pressing mechanism is located in the treatment chamber corresponding to the area where the syringe needle and the barrel are connected. The thermo-pressing mechanism can hold the syringe tightly and heat the holding area.

[0006] Optionally, the pulling and pressing mechanism includes two sets of opposing pulling and pressing parts. Each pulling and pressing part includes a slide, a first telescopic power source, and a V-shaped clamping block. The slide is slidably disposed along the moving cavity. The V-shaped clamping block is hinged to the slide at its inflection point and the V-shaped opening faces the center of the moving cavity. One end of the first telescopic power source is hinged to the slide, and the other end is hinged to one end of the V-shaped clamping block. During the extension and retraction of the first telescopic power source, the other end of the V-shaped clamping block can be flipped upward or downward.

[0007] Optionally, the hot pressing mechanism includes two sets of hot pressing sections arranged opposite each other. Each hot pressing section includes a second telescopic power source and a hot pressing plate. The hot pressing plate is connected to the second telescopic power source and can move towards the center of the moving cavity. The hot pressing plate can generate heat.

[0008] Optionally, the movable cavity is provided with a lead screw, the slide is threadedly connected to the lead screw, and the lead screw is driven by a rotary power source.

[0009] Optionally, the hot pressing plate is provided with a hot pressing cavity on the side facing the middle of the moving cavity. When the two sets of hot pressing parts move relative to each other and fit together, the hot pressing cavity can be assembled into a vertical blind hole.

[0010] Optionally, the surfaces of the two sets of hot press plates below the hot press cavity area are arranged with vertical ridges and grooves, which are used to increase the clamping force on the needle.

[0011] Optionally, the rolled edge area is provided with a support rod along the length direction of the moving cavity, the support rod being able to slidably support the rolled edge of the syringe barrel; and / or, the push handle area is provided with a support rod along the length direction of the moving cavity, the support rod being able to slidably support the push handle of the syringe.

[0012] Optionally, the end of the moving cavity away from the treatment cavity is hinged with a flip plate, and the outer end of the flip plate is connected to the housing through an elastic element. Initially, the flip plate is horizontal.

[0013] Optionally, the bottom of the movable cavity is provided with a needle storage cavity, the needle storage cavity is provided with a needle inlet corresponding to the treatment cavity area, and the needle storage cavity is provided with a heating element or contains disinfectant.

[0014] Optionally, the end of the movable cavity away from the treatment cavity is provided with a syringe receiving chamber.

[0015] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: This medical waste recycling and processing device achieves multiple protective effects through structural innovation: the coordinated design of the treatment chamber and the moving chamber, along with the conical centering outlet, ensures precise syringe positioning; the clamping mechanism, through a triple action of clamping, moving, and sliding, achieves physical separation of the syringe while automatically sealing the syringe body, effectively blocking the leakage path of residual drugs; the heat-pressing mechanism heats and melts the needle connection point, thoroughly separating the sharps and inactivating surface pathogens, while a unified storage structure prevents cross-contamination. The entire device controls both biological and physical risks at the source, significantly improving the safety of the temporary storage of medical waste. Attached Figure Description

[0030] 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.

[0031] 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 one of ordinary skill in the art to which this invention pertains.

[0032] A medical waste recycling and processing device, please refer to the appendix. Figures 1-12 One possible implementation method is as follows: Processing chamber 1, moving chamber 2, pressing mechanism 5, and hot pressing mechanism 6; See Figure 5 The treatment chamber 1 is vertically oriented and has a dispensing port 11 at the top. The dispensing port 11 can be tapered and its shape matches the syringe plunger, allowing for automatic centering when the syringe is inserted. The syringe can be vertically inserted into the treatment chamber 1. (See reference...) Figure 10 and Figure 12 The moving cavity 2 is arranged laterally and one end is connected to the treatment cavity 1. The cross section of the moving cavity 2 includes a body area 21, a push handle area 22 and a rolled edge area 23 that are sequentially matched with the syringe body, the syringe push handle and the rolled edge of the syringe barrel. The pressure-removing mechanism 5 is located in the treatment chamber 1 corresponding to the syringe barrel area. The pressure-removing mechanism 5 can hold the syringe tightly and can drive the syringe to move up and down (along the axis of the treatment chamber 1). The pressure-removing mechanism 5 can also slide along the moving chamber 2 with the syringe. The hot pressing mechanism 6 is located in the treatment chamber 1 corresponding to the area where the syringe needle and the barrel are connected. The hot pressing mechanism 6 can hold the syringe tightly and heat the holding area.

[0033] In the above embodiment, the main working process of the device is as follows: After the syringe is used, the medical staff inserts the syringe needle downwards into the treatment chamber 1, and simultaneously presses the syringe plunger to move the piston into the innermost part of the syringe barrel. Then the device starts working (a start button can be set on the device), specifically: Step 1: The clamping mechanism 5 holds the syringe tightly to fix it in place. The heating mechanism 6 is close to the area where the syringe needle connects to the barrel. It should ensure that the needle is clamped and heat the corresponding area to soften the plastic in the area where the needle connects to the barrel. Step 2: The hot pressing mechanism 6 remains in its original state, the pressure pulling mechanism 5 holds the syringe tightly and moves upward, the syringe barrel separates from the needle, the barrel moves upward relative to the pressure pulling mechanism 5, and the needle remains stationary relative to the hot pressing mechanism 6. Step 3: The hot pressing mechanism 6 is released, the needle falls to the receiving device below, the pulling mechanism 5 holds the syringe and moves down, the hot pressing mechanism 6 closes, heats up and squeezes the area where the needle and the barrel are connected, the plastic melts and seals the syringe mouth. Step 4: The hot pressing mechanism 6 is released, the pressure pulling mechanism 5 holds the syringe and moves it along the moving cavity 2 and away from the treatment cavity 1. Then the pressure pulling mechanism 5 releases the syringe and returns to the treatment cavity 1 to prepare for the next treatment.

[0034] This device achieves efficient and safe syringe handling through structural optimization. The syringe separation and sealing functions form a dual protection system. The thermocompression mechanism 6 softens the plastic at the connection area between the needle and the syringe barrel through heating, and, in conjunction with the upward movement of the extraction mechanism 5, achieves physical separation, effectively eliminating the risk of sharps exposure and allowing for centralized needle handling. After separation, during the downward movement of the extraction mechanism 5, the thermocompression mechanism 6 reheats and squeezes the syringe opening, using the melted plastic to form a sealing layer, completely blocking the leakage path of residual medication and controlling the risk of biological contamination at the source. After use, the syringes are properly stored before being collected by a specialized processing unit, ensuring proper storage and preventing medication leakage, cross-infection of pathogens, and injuries from sharps.

[0035] In one possible implementation, see Appendix Figure 11 The pressure-pulling mechanism 5 includes two sets of opposing pressure-pulling parts. Each pressure-pulling part includes a slide 51, a first telescopic power source 52, and a V-shaped clamp 53. The slide 51 is slidably arranged along the moving cavity 2. The V-shaped clamp is hinged to the slide 51 at its inflection point, with the V-shaped opening facing the middle of the moving cavity 2. The two V-shaped clamps 53 clamp the syringe from opposite sides of the syringe body. One end of the first telescopic power source 52 is hinged to the slide 51, and the other end is hinged to one end of the V-shaped clamp. During the extension and retraction of the first telescopic power source 52, the other end of the V-shaped clamp can be flipped up or down. When this end of the V-shaped clamp 53 is horizontal, that is, perpendicular to the surface of the syringe body, the length from the inflection point of the V-shaped clamp 53 to the end is slightly greater than the distance from the inflection point to the edge of the syringe body. Therefore, the flipping end of the V-shaped clamp is provided with an elastic material, such as rubber, which can elastically deform during the compression process to shorten the length and increase the interaction force.

[0036] See Figure 3 , Figure 3This is the initial state after the syringe is inserted. When the first telescopic power source 52 retracts, the V-shaped clamp 53 is pulled upwards and flipped. Because the length of the V-shaped clamp 53 in contact with the syringe is wider than its distance from the syringe body, the end of the V-shaped clamp 53 will squeeze the syringe. If the upward flip angle of the V-shaped clamp 53 is large enough, after the syringe moves upwards a certain distance, it will become... Figure 3 The state is shown in the dashed line; at this time, if the first telescopic power source 52 pushes down, the V-shaped clamp 53 is pulled and flipped downwards, and the end of the V-shaped clamp 53 will squeeze the syringe. If the downward flipping angle of the V-shaped clamp 53 is large enough, it will become... Figure 3 The solid line indicates that the state has returned to its initial state.

[0037] In the above embodiments, the pressure-pulling mechanism 5 achieves precise and reliable clamping and driving functions through an innovative mechanical structure design. Its core consists of two symmetrically arranged pressure-pulling sections. Each section uses a slide 51 as its base, and works with the first telescopic power source 52 to drive the V-shaped clamping block 53 to achieve a flipping action, thereby moving the syringe up or down. The special structure of the V-shaped clamping block 53 (inflection point hinge + elastic end) forms an adaptive clamping mechanism: when the telescopic power source contracts, the clamping block flips upward and applies an upward pulling force to the syringe body through the elastic rubber end, using elastic deformation to compensate for dimensional differences and ensure clamping stability; in reverse driving, it flips downward to achieve a pressing effect. This design ensures reliable fixation of the syringe during processing and achieves upward and downward pulling through elastic buffering. Combined with the guiding effect of the moving cavity 2, the device can accurately complete the entire process of upward needle separation, downward sealing of the syringe outlet, and lateral transfer, significantly improving the automation level and operational safety of medical waste treatment, while reducing equipment wear and extending service life.

[0038] In one possible implementation, see Appendix Figure 4 and Figure 7 The hot pressing mechanism 6 includes two sets of opposing hot pressing sections. Each hot pressing section includes a second telescopic power source 61 and a hot pressing plate 62. The hot pressing plate 62 is connected to the second telescopic power source 61 and can move towards the center of the moving cavity 2. The hot pressing plate 62 can generate heat, which can be electric heating, i.e., resistance heating. A hot pressing cavity 621 is provided on the side of the hot pressing plate 62 facing the center of the moving cavity 2. When the two sets of hot pressing sections move relative to each other and fit together, the hot pressing cavity 621 can be assembled into a vertical blind hole.

[0039] In the above embodiments, the hot-pressing mechanism 6 achieves precise and efficient separation and sealing functions through the collaborative design of two hot-pressing sections. The two sets of hot-pressing sections are driven by the second telescopic power source 61, moving the hot-pressing plate 62 towards the center of the moving cavity 2. Its electric heating method (resistance heating) ensures controllable temperature and rapid response. The key innovation is the hot-pressing cavity 621 located inside the hot-pressing plate 62: when the two sets of hot-pressing sections are closed, the hot-pressing cavity 621 forms a vertical blind hole. This structure can precisely wrap the area connecting the syringe needle and the syringe barrel, and the mating surface at the bottom of the blind hole clamps the syringe shaft. During the separation stage, the blind hole applies uniform pressure to concentrate heat on the softened plastic area, achieving non-destructive separation of the needle shaft in conjunction with the upward movement of the pulling-out mechanism 5. During the sealing stage, the blind hole acts as a molding die, melting the plastic through compression to form a sealing layer, preventing leakage of the medication during subsequent temporary storage of the syringe. This design enables the hot-pressing process to have both separation and sealing functions.

[0040] In one possible implementation, see Appendix Figure 11 The moving cavity 2 is equipped with a lead screw 24, and the slide 51 is threadedly connected to the lead screw 24. The lead screw 24 is driven by a rotary power source, and the relative distance between the two sets of lead screws 24 is wider than the width of the syringe plunger. In the above embodiment, the moving cavity 2 realizes the clamping mechanism 5 to hold the syringe and perform lateral movement control through the lead screw transmission system.

[0041] In one possible implementation, see Appendix Figure 11 The two sets of hot-pressing plates 62 have vertically arranged raised and recessed strips 622 on their surfaces below the hot-pressing cavity 621. These strips increase the clamping force on the needle. The array of raised and recessed strips 622 added to the hot-pressing plates 62 below the hot-pressing cavity 621 enhances the mechanical interlocking effect through surface texture. This structure significantly improves the clamping stability of the needle during the hot-pressing separation stage, preventing the needle from moving upwards simultaneously with the syringe barrel and thus failing to be effectively pulled out.

[0042] In one possible implementation, see Appendix Figure 11 The crimped area 23 is provided with a support rod 25 along the length of the moving cavity 2, which can slide to support the crimped edge of the syringe barrel; and / or, the push handle area 22 is provided with a support rod 25 along the length of the moving cavity 2, which can slide to support the push handle of the syringe. The stability of syringe movement is optimized through a line contact support method. The support rod 25 is arranged along the length of the moving cavity 2, forming linear contact with the crimped edge of the syringe barrel or the push handle. Compared with the traditional surface contact design, this reduces sliding friction, ensuring smooth and unobstructed syringe movement when the pressure-release mechanism 5 clamps the syringe barrel and the screw is driven.

[0043] In one possible implementation, see Appendix Figure 10The moving cavity 2 is located away from the treatment cavity 1. A flip plate 7 is hinged to the end of the moving cavity 2. The outer end of the flip plate 7 is connected to the housing through an elastic element 8. Initially, the flip plate 7 is horizontal. When the syringe is moved to the upper side of the flip plate 7, the flip plate 7 flips down into an inclined plane due to the weight of the syringe. When the pressure release mechanism 5 releases the syringe, the syringe slides into the storage area along the inclined plane.

[0044] A gravity-sensing flip plate 7 is added to the end of the moving cavity 2, forming an automated unloading system. Initially, the flip plate 7 remains horizontal under the action of the elastic element 8, smoothly engaging with the moving cavity 2. When the extraction mechanism 5, carrying the processed syringe, moves to the end, the syringe's gravity overcomes the elastic force of the elastic element 8, causing the flip plate 7 to flip downwards, forming an inclined plane, achieving unloading without power. This design replaces electronic sensors with mechanical gravity sensing, reducing equipment costs and improving reliability. Simultaneously, the inclined structure ensures the syringe slides directionally into the storage area, preventing scattering. Combined with the preceding line contact support and thermoforming process, a complete process from processing to storage is formed, improving the efficiency of medical waste treatment.

[0045] In one possible implementation, see Appendix Figure 11 The bottom of the movable chamber 2 is equipped with a needle storage chamber 3, which has a needle inlet corresponding to the treatment chamber 1 area. The needle storage chamber 3 contains a heating element or is filled with disinfectant. The needle inlet connects to the treatment chamber 1, ensuring that the separated needle falls directly into the chamber, avoiding the risk of leakage. The heating element inside the chamber can inactivate pathogens through high temperature, or chemically sterilize using disinfectant; these two modes can be flexibly switched according to the medical scenario. This design simultaneously completes the storage and harmless treatment of sharps, constructing a safety net.

[0046] In one possible implementation, see Appendix Figure 5 The end of the moving cavity 2 away from the treatment cavity 1 is provided with a syringe receiving chamber 4.
