Description

Technical Field

[0001] This invention belongs to the technical field of medical waste treatment equipment, and more specifically, it relates to a device for destroying vascular interventional consumables. Background Technology

[0002] Currently, most vascular interventional consumables used in clinical practice are disposable medical supplies, such as catheters and guidewires. These medical consumables, with their special material properties, are often directly discarded into ordinary trash cans. Their sharp ends can easily puncture trash bags, causing contamination. Furthermore, consumables with shape memory function can expand in volume after external force is removed and may even rebound suddenly under pressure, posing occupational exposure risks to medical waste disposal personnel. In addition, interventional consumables that have not undergone physical destruction are at risk of being recycled and refurbished by criminals, potentially re-entering the medical market through irregular channels, posing significant safety hazards to patients. Current medical waste disposal methods lack specialized destruction equipment for the characteristics of vascular interventional consumables, failing to achieve irreversible physical deformation of the consumables. This fails to eliminate safety hazards and cannot prevent the risk of reuse. Conventional medical waste shredding equipment is often bulky and complex to operate, unsuitable for immediate processing of interventional consumables in operating rooms and other medical settings. This forces these high-risk medical wastes to undergo multiple transfer stages before final disposal, increasing safety risks and management costs at each stage. Summary of the Invention

[0003] The purpose of this application is to provide a device for destroying vascular interventional consumables, so as to solve the technical problems of vascular interventional consumable waste disposal in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: A device for destroying vascular interventional consumables is provided, comprising: Collection bucket; A bucket lid is placed over the opening of the collection bucket, and the bucket lid is provided with a feed inlet; A feeding assembly is located inside the lid. The feeding assembly includes a feeding channel that extends along a spiral direction and gradually narrows from the outside to the inside, and a feeding roller on the feeding channel. After the vascular interventional consumable enters the feeding channel from the inlet, it continues to be pushed inward by the feeding roller. An extrusion assembly is located inside the barrel lid. The extrusion assembly includes a mold body with a mold cavity, an upper mold located at the upper end of the mold cavity, and a bottom mold located at the lower end of the mold cavity. It also includes a pressure drive for driving the upper mold. The upper mold has a through hole, and the feeding channel communicates with the mold cavity through the through hole. The vascular interventional consumables are coiled and stacked in the mold cavity after being guided by the feeding channel extending in a spiral direction. One end of the pressure drive is installed inside the barrel lid, and the other end is driven and connected to the upper mold to drive the upper mold to move in the mold cavity. The pressure drive drives the upper mold to close towards the bottom mold to crush the coiled and stacked vascular interventional consumables in the mold cavity to plastic deformation. After the bottom mold exits the mold cavity, the upper mold pushes the crushed and deformed vascular interventional consumables into the collection bucket.

[0005] As a further improvement to the above technical solution: Optionally, a wire winding mechanism is provided on the bucket lid, which includes a wire feeding assembly, a wire channel, and a winding assembly. The wire feeding assembly is located at one end of the wire channel, and the winding assembly is located at the other end of the wire channel. The wire feeding assembly feeds the wire through the wire channel to the winding assembly. The winding assembly is used to wind the wire onto the vascular interventional consumable and coil it together with the vascular interventional consumable into the mold cavity.

[0006] Optionally, the wire feeding assembly includes wire, a winding roller, a winding roller drive, and a wire cutter. The winding roller is rotatably connected to the barrel cover and driven by the winding roller drive. The wire is wound on the winding roller, with one end of the wire extending into the wire channel. The winding roller drive drives the winding roller to rotate, so as to unwind the wire wound on the winding roller and feed it into the wire channel. The wire cutter is located at the entrance end of the wire channel to cut the wire.

[0007] Optionally, the barrel cover is provided with a wire-spinning mounting cavity, the wire-spinning mounting cavity having an opening communicating with the outside, and the roller is detachably connected to the wire-spinning mounting cavity.

[0008] Optionally, the winding assembly includes a winding drive and a winding connector, the winding connector being rotatably connected to the bucket lid about its axial direction, and the winding drive being driven to the winding connector. The feeding channel includes a front feeding section and a rear feeding section. The front feeding section and the twisted wire channel converge at one end of the twisted connector. The rear feeding section is connected to the other end of the twisted connector. The twisted connector includes two through holes arranged axially and spaced apart from each other. The vascular interventional consumable passes through one through hole, and the twisted wire passes through the other through hole. By rotating the twisted connector, the vascular interventional consumable and the twisted wire are twisted together and fed to the rear feeding section.

[0009] Optionally, the extrusion assembly includes a bottom mold drive unit mounted on the bucket lid. The bottom mold has a discharge hole corresponding to the mold cavity. When the bottom mold drive unit drives the discharge hole on the bottom mold to misalign with the mold cavity, the upper mold closes towards the bottom mold to crush the vascular interventional consumables coiled and stacked in the mold cavity into plastic deformation. When the bottom mold drive unit drives the discharge hole on the bottom mold to align with the mold cavity, the upper mold pushes the crushed and deformed vascular interventional consumables into the collection bucket.

[0010] Optionally, the barrel cover includes an upper cover and a lower cover, which together form a device cavity. The feeding assembly and the extrusion assembly are both located within the device cavity. The feeding port is located on the upper cover, and the bottom mold is supported on the lower cover. The lower cover has an opening corresponding to the discharge hole.

[0011] Optionally, the barrel lid is further provided with a feed inlet cover, which is rotatably connected to the barrel lid. The feed inlet cover is provided with a feed hole corresponding to the feed inlet. When the feed hole corresponds to the feed inlet, the feed inlet is open; when the feed hole is misaligned with the feed inlet, the feed inlet is closed.

[0012] Optionally, the system includes a collection bag fitted inside a collection bucket, and the collection bucket is also equipped with an exhaust device. The air inlet of the exhaust device is located inside the collection bucket, and the air outlet of the exhaust device is located outside the collection bucket. The exhaust device is used to discharge the air between the collection bag and the collection bucket.

[0013] Optionally, a lid lock is included for locking the lid and the collection bucket.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The vascular interventional consumables crushing device provided in this application includes a collection bucket, a bucket lid, a feeding assembly, and a crushing assembly. The bucket lid covers the opening of the collection bucket and has a feeding port. The feeding assembly is installed inside the bucket lid and includes a spirally extending and tapering feeding channel and a feeding roller to guide the consumables into the processing area. The crushing assembly includes a mold cavity, an upper mold, a lower mold, and a pressure drive component. The upper mold has a through hole connecting the feeding channel and the mold cavity. The pressure drive component drives the upper mold and the lower mold to close, resulting in plastic deformation. After the lower mold exits, the crushed consumables are pushed into the collection bucket. When the vascular interventional consumables enter the device through the feeding port, the spirally tapering channel structure guides them to form a multi-layered coiled state. The feeding roller continuously pushes the consumables, causing them to form a dense accumulation within the mold cavity. When the pressure drive component drives the upper mold to press down, the mold cavity space is compressed to 30%-40% of its original height, and the consumables undergo plastic deformation under three-dimensional compression. After the bottom mold exits the mold cavity via the translation mechanism, the upper mold continues to descend, completely pushing the deformed consumable away from the processing area. During this process, dislocation slip occurs in the microcrystalline structure of the consumable, causing it to completely lose its shape memory function.

[0015] Compared to existing technologies, traditional processing methods only involve simple folding or cutting, leaving the consumables with over 50% elastic recovery. This solution uses a spiral feeding system to create an ordered stacked structure, ensuring pressure is evenly distributed to each coiled ring. The closed compression of the mold cavity subjects the consumables to both axial and radial pressure, generating composite stress exceeding the material's yield strength. This application effectively eliminates the sharp edges and elastic recovery of vascular interventional consumables, resulting in a flat, disc-shaped structure after processing. The destroyed consumables cannot be covered by polyethylene film, completely eliminating the risk of puncturing waste bags. The material's morphological destruction rate reaches over 98%, losing its structural integrity as a medical device and physically preventing secondary use. The processing is automated in a closed environment, eliminating the need for operators to directly handle undestroyed consumables, avoiding occupational exposure risks. Destruction also reduces space requirements and improves space utilization within the collection bin. Attached Figure Description

[0019] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] Unless otherwise defined, all technical terms used herein have the same meaning as commonly understood by those skilled in the art. The technical terms used herein are for the purpose of describing particular embodiments only and are not intended to limit the scope of the invention.

[0024] Current technologies pose significant safety risks in the post-operative handling of disposable vascular interventional consumables. Traditionally, used consumables are simply discarded into ordinary trash cans. Because the sharp ends of the consumables are not treated, they can easily puncture trash bags, causing secondary contamination. The inherent elasticity of the consumables means they can rebound after being compressed, posing a risk of injury to operators. More seriously, undamaged consumables can be easily recycled and reused by criminals, threatening patient safety.

[0025] To address these issues, researchers observed that the key to consumable structural damage lies in eliminating its elastic recovery capability. Analysis of the consumable's morphological characteristics revealed that the spiral winding structure can increase local stress concentration points, which, combined with directional pressure, can induce irreversible deformation. Simultaneously, a closed processing environment must be established to prevent material leakage during operation.

[0026] like Figures 1 to 6 As shown, this application proposes a crushing device including a collection bucket 1, a bucket lid 2, a feeding assembly 3, and a crushing assembly 4. The bucket lid 2 covers the opening of the collection bucket 1 and has a feeding port. The feeding assembly 3 is installed inside the bucket lid 2 and includes a spirally extending and tapering feeding channel and a feeding roller to guide the consumables into the processing area. The crushing assembly 4 includes a mold cavity, an upper die 42, a bottom die 43, and a pressure driving component 44. The upper die 42 has a through hole connecting the feeding channel and the mold cavity. The pressure driving component 44 drives the upper die 42 and the bottom die 43 to close and produce plastic deformation. After the bottom die 43 retracts, the crushed consumables are pushed into the collection bucket 1.

[0027] Among them, the collection bucket 1 refers to the container used to hold the material after it has been deformed. It can be made of stainless steel or plastic. Its height can be 600-800 mm and its diameter can be 400-500 mm. It is used to receive consumables that have undergone plastic deformation.

[0028] The spiral extension structure of the feed channel refers to the channel centerline following an Archimedean spiral trajectory, with the channel width gradually decreasing from 50 mm at the inlet end to 15 mm at the outlet end, forcing the consumables to form a coiled structure.

[0029] Feeding rollers refer to rotating rollers with a rubber coating on their surface. The diameter of the rollers can be 30-50 mm. They are driven by a motor to propel consumables at a speed of 20-30 revolutions per minute.

[0030] The mold cavity refers to the cylindrical cavity enclosed by the mold body 41, with an inner diameter of 80-100 mm and a height of 120-150 mm, used to accommodate the consumables for winding and forming.

[0031] The pressure drive component 44 refers to a hydraulic cylinder or electric actuator with an output pressure range set at 5-8 tons and a stroke of 80-100 mm, ensuring the generation of extrusion force sufficient to cause plastic deformation of the metal material.

[0032] Specifically, after the vascular interventional consumable enters the device through the inlet, the spirally converging channel structure guides it to form a multi-layered coiled state. The continuous pushing by the feed rollers causes the consumable to form a dense accumulation within the mold cavity. When the pressure drive 44 drives the upper mold 42 downwards, the mold cavity space is compressed to 30%-40% of its original height, and the consumable undergoes plastic deformation under three-dimensional compression. After the bottom mold 43 exits the mold cavity via the translation mechanism, the upper mold 42 continues to descend 10-15 mm, completely pushing the deformed consumable away from the processing area. During this process, dislocation slip occurs in the microcrystalline structure of the consumable, the elastic modulus decreases by 60%-70%, and it completely loses its shape memory function.

[0033] Compared to existing technologies, traditional processing methods only involve simple folding or cutting, leaving the consumables with an elastic recovery rate of over 50%. This solution uses a spiral feeding system to create an ordered stacked structure, allowing pressure to be evenly distributed to each coiled ring. The closed compression of the die cavity subjects the consumables to both axial pressure and radial extrusion force, generating composite stress exceeding the material's yield strength. Experimental data shows that consumables treated with this device have a springback rate of less than 5% and a puncture force reduction of over 90%, achieving an irreversible deformation effect.

[0034] Through the above technical solution, this application effectively eliminates the sharp edges and elastic recovery ability of vascular interventional consumables. The processed material has a flat, disc-like structure with a maximum thickness of no more than 10 mm. Testing shows that the destroyed consumable cannot penetrate a 0.1 mm thick polyethylene film, completely eliminating the risk of puncturing waste bags. The material's morphological destruction rate reaches over 98%, losing its structural integrity as a medical device and physically eliminating the possibility of secondary use. The processing is automatically completed in a closed environment, eliminating the need for operators to directly contact undestroyed consumables, avoiding occupational exposure risks. Destruction also reduces the space occupied, improving the space utilization rate within the collection bin 1.

[0035] This application further proposes a wire winding mechanism 5 disposed on the barrel cover 2, which has a wire feeding assembly 51, a wire channel 52, and a winding assembly 53. The wire feeding assembly 51 is located at one end of the wire channel 52, and the winding assembly 53 is located at the other end of the wire channel 52. The wire feeding assembly 51 conveys the wire through the wire channel 52 to the winding assembly 53. The winding assembly 53 is used to wind the wire 511 onto the vascular interventional consumable and coil and stack it together with the vascular interventional consumable into the mold cavity.

[0036] The wire feeding assembly 51 is a device for storing and directionally conveying wires 511. Specifically, it can use a roller 512 to store the wires 511 and control the release amount of the wires 511 through a drive component. The rotation speed of the roller 512 can be adjusted to match the consumable conveying speed. The wire channel 52 is the path that guides the wires 511 and consumables to converge. Specifically, it can use a smooth internal tubular structure to ensure that the wires 511 and consumables do not become entangled or misaligned within the channel. The winding assembly 53 is a mechanism for mechanically winding the wires 511 and consumables. Specifically, it can use a rotary joint to drive the wires 511 and consumables to spirally wind together. The rotation speed can control the winding density.

[0037] Specifically, the wire feeding assembly 51 directionally conveys the metal wire 511 through the wire channel 52 to the winding assembly 53, while the vascular interventional consumable enters through the feeding channel. In the winding assembly 53, the wire 511 and the consumable are synchronously pulled, and the rotational motion of the winding assembly 53 causes them to form a helical winding structure. After the wound composite enters the mold cavity, the wire 511 embeds into the surface of the consumable, forming a mechanical interlock. During subsequent extrusion, the rigidity of the wire 511 hinders the elastic recovery of the consumable, while the shear stress generated at the contact surface exacerbates the plastic deformation of the consumable. The interlacing of the wire 511 and the consumable results in the deformed product forming an inseparable mixture.

[0038] Compared to existing technologies, traditional destruction devices rely solely on mechanical compression to break the shape of the consumable, but cannot solve the problem of elastic material rebound. Existing technologies do not employ the twisted wire 511 winding method, resulting in the consumable potentially returning to its original shape after destruction or being manually separated and recycled. This solution uses a composite winding of twisted wire 511 and the consumable, adding structural locking to the physical destruction process, forming a dual destruction mechanism.

[0039] Through the above technical solution, this application effectively solves the problem of shape recovery caused by material elasticity after vascular interventional consumables are destroyed. The twisted wire 511 is embedded inside the consumable to form irreversible structural damage. At the same time, the mixed entanglement significantly increases the difficulty of recycling and separation, completely blocking the possibility of secondary use.

[0040] This application further proposes a wire feeding assembly 51 including wire 511, a winding roller 512, a winding roller drive 513, and a wire cutter. The winding roller 512 is rotatably connected to the barrel cover 2 and driven by the winding roller drive 513. The wire 511 is wound on the winding roller 512 and extends into the wire channel 52. The winding roller drive 513 drives the winding roller 512 to rotate to unfold the wire 511 and feed it into the channel. The wire cutter is provided at the entrance end of the channel for cutting the wire 511.

[0041] Among them, the roller drive 513 refers to the mechanical transmission device that drives the roller 512 to rotate. Specifically, it can be implemented by a stepper motor or a servo motor. The release length of the twisted wire 511 can be precisely adjusted by controlling the rotation angle of the motor.

[0042] Among them, the wire cutting component refers to the cutting device installed at the inlet end of the wire channel 52. Specifically, it can be implemented by a pneumatic shear or an electric gate, and is cut off immediately after the wire 511 is conveyed to avoid residue.

[0043] The rotatable connection of the roller 512 refers to the structure in which the roller 512 is mounted on the barrel cover 2 via a bearing or a rotating shaft. Specifically, it can be achieved by using a rotating shaft with a buckle, which facilitates quick disassembly and replacement of the twisted wire 511 roll material.

[0044] Specifically, when the roller drive 513 is activated, it drives the roller 512 to rotate and release the twisted wire 511. The twisted wire 511 enters the twisted wire channel 52 through the channel inlet end. The rotation speed of the drive is synchronized with the feed speed of the vascular interventional consumables, ensuring that the twisted wire 511 and the consumables form a stable winding at the winding assembly 53. When the twisted wire 511 reaches the preset length, the cutting component immediately cuts the twisted wire 511. The cutting position is located outside the channel inlet end, so that the remaining twisted wire 511 segment is completely removed from the equipment. The detachable structure of the roller 512 allows for quick replacement of the roller 512 when the twisted wire 511 is exhausted, avoiding excessive downtime.

[0045] Traditional equipment relies on manual placement of the twisted wire 511, resulting in inconsistent winding lengths and potential clogging of the equipment by residual wire segments after cutting. This solution achieves precise control of the twisted wire 511 length through the roller drive component 513, eliminates the risk of residue through the design of the cutting component position, and improves the continuity of operation through the detachable structure of the roller 512.

[0046] Through the above technical solutions, this application achieves synchronous quantitative conveying of the twisted wire 511 and consumables, ensuring that the winding length of each consumable is consistent; the cutting action is completed on the outside of the channel to prevent the twisted wire 511 debris from entering the equipment; the quick replacement mechanism of the roller 512 maintains the continuous operation capability of the equipment and eliminates the risk of consumable recycling caused by the residue of twisted wire 511 from the root.

[0047] This application further proposes to provide a wire-spinning mounting cavity on the barrel cover 2, the wire-spinning mounting cavity having an opening communicating with the outside, and the winding roller 512 being detachably connected to the wire-spinning mounting cavity.

[0048] The wire-spinning mounting cavity refers to the accommodating space inside the barrel cover 2 for fixing the winding roller 512. Specifically, it can be achieved using a groove structure formed by injection molding or machining, with the dimensions of the groove matching the outer diameter of the winding roller 512. The opening refers to the portion of the wire-spinning mounting cavity that faces outwards from the barrel cover 2. This can be achieved by creating rectangular or circular through holes on the surface of the barrel cover 2, allowing the winding roller 512 to be directly inserted or removed from the outside. The detachable connection refers to the temporary fixing of the winding roller 512 to the mounting cavity using snap-fit, magnetic attraction, or plug-in methods. Specifically, it can be achieved using spring snaps or a sliding rail structure to ensure the stability of the winding roller 512 during operation.

[0049] Specifically, the open design of the wire-twisting installation cavity allows operators to directly observe the remaining amount of wire 511 on the winding roller 512 without removing the drum cover 2, and to quickly replace the winding roller 512 manually. When the wire 511 is depleted, the winding roller 512 is released through a snap-fit ​​structure and removed from the open opening. A new winding roller 512 is inserted into the installation cavity through the open opening and secured by the snap-fit, all without interrupting equipment operation. This structure avoids the cumbersome steps of stopping the machine to disassemble the housing required by traditional embedded winding rollers 512, and at the same time, the combination of the open opening and the detachable structure ensures that the wire 511 supply process is not affected by equipment maintenance.

[0050] Traditional rollers 512 are typically bolted or embedded inside the cover 2, requiring the removal of multiple fasteners or opening of the equipment casing for replacement, leading to prolonged maintenance time and the risk of component loss. This solution simplifies roller 512 maintenance to a single pick-and-place action through an open mounting cavity and detachable connection structure, significantly reducing downtime. This application enables rapid replacement and maintenance of the roller 512, avoiding equipment downtime due to depletion of the wire 511, ensuring continuous and stable entanglement between the wire 511 and the vascular interventional consumables, thereby maintaining the crushing efficiency of the compression assembly.

[0051] This application further proposes a winding assembly 53 including a winding drive 531 and a winding connector 532. The winding connector 532 is rotatably connected to the bucket cover 2 about its axial direction. The winding drive 531 is driven to the winding connector 532. The feeding channel includes a feeding front section 31 and a feeding rear section 32. The feeding front section 31 and the twisting wire channel 52 both converge at one end of the winding connector 532. The feeding rear section 32 is connected to the other end of the winding connector 532. The winding connector 532 includes two through holes arranged axially and spaced apart from each other. The vascular interventional consumable passes through one through hole, and the twisted wire 511 passes through the other through hole. By rotating the winding connector 532, the vascular interventional consumable and the twisted wire 511 are wound together and fed to the feeding rear section 32.

[0052] The winding drive component 531 is a mechanical device that provides rotational power, which can be implemented using a servo motor or a stepper motor. Its output shaft is connected to the winding connector 532 via a coupling. The winding connector 532 is a rotating component with a double-through-hole structure, which can be made of stainless steel or hard alloy material. The distance between the two through holes can be adjusted according to the diameter of the consumable. Rotation causes the twisted wire 511 and the consumable to form a spiral twist. The front feeding section 31 and the rear feeding section 32 are segmented guide channels, which can be made of smooth-walled metal tubes or polymer material tubes. The front section is used to independently transport the consumable and the twisted wire 511, and the rear section is used to guide the twisted composite into the mold cavity.

[0053] Specifically, when the winding drive 531 is activated, the winding connector 532 rotates axially at a preset speed. The vascular interventional consumable is inserted through one through-hole of the feed section 31, and the twisted wire 511 is inserted through another through-hole, remaining separate within the winding connector 532. As the winding connector 532 continues to rotate, the consumable and the twisted wire 511 are forcibly twisted at the through-hole outlet, forming a helical winding structure. The twisted composite is fed into the feed section 32 and, under helical guidance, coils and accumulates in the mold cavity. By controlling the speed and direction of rotation of the winding connector 532, the twisting density of the twisted wire 511 and the consumable can be adjusted to ensure a tight bond between them.

[0054] Traditional winding methods rely on manual operation or simple mechanical clamping, resulting in a loose winding between the twisted wire 511 and the consumable, which is prone to separation during subsequent extrusion. This solution uses a rotating winding joint 532 to force a spiral twist, creating a mechanical interlocking structure between the twisted wire 511 and the consumable, preventing easy separation even under external pressure. This application solves the problem of easy separation and recovery after deformation due to loose winding between the vascular interventional consumable and the twisted wire 511. The spiral twisted structure of the twisted wire 511 and the consumable undergoes plastic deformation during extrusion, forming an irreversible physical bond, significantly increasing the difficulty of separation. When the twisted composite is crushed within the mold cavity, the twisted wire 511 embeds into the consumable, further disrupting its original shape and effectively preventing the deformed material from springing back or being manually disassembled and recycled.

[0055] This application further proposes that the extrusion assembly 4 includes a bottom mold drive 45 installed on the barrel cover 2. The bottom mold 43 has a discharge hole corresponding to the mold cavity. When the bottom mold drive 45 drives the discharge hole on the bottom mold 43 to misalign with the mold cavity, the upper mold 42 closes to the bottom mold 43 to crush the vascular interventional consumables coiled and stacked in the mold cavity into plastic deformation. When the bottom mold drive 45 drives the discharge hole on the bottom mold 43 to correspond with the mold cavity, the upper mold 42 pushes the crushed and deformed vascular interventional consumables into the collection barrel 1.

[0056] The bottom mold drive component 45 refers to a linear motion mechanism capable of driving the bottom mold 43 to perform horizontal displacement. Specifically, it can be implemented using an electric push rod or a pneumatic cylinder. The positional matching of the unloading hole and the mold cavity is achieved by controlling the horizontal displacement of the bottom mold 43. The unloading hole is a through-hole structure penetrating the thickness of the bottom mold 43, and its diameter can be comparable to the diameter of the mold cavity. When the bottom mold 43 moves to the point where the unloading hole and the mold cavity are coaxial, a material falling channel is formed. Mold cavity misalignment refers to a spatial offset between the axis of the unloading hole of the bottom mold 43 and the axis of the mold cavity. In this case, the solid part of the bottom mold 43 closes the bottom of the mold cavity, forming a sealed crushing space.

[0057] Specifically, during the crushing operation, the bottom mold drive 45 pushes the bottom mold 43 so that the unloading hole is offset from directly below the mold cavity, at which point the bottom of the mold cavity is completely sealed by the bottom mold 43. The upper mold 42 moves downwards under the action of the pressure drive 44, applying vertical pressure to the coiled vascular interventional consumables within the mold cavity, causing them to undergo plastic deformation. After crushing is complete, the bottom mold drive 45 drives the bottom mold 43 to move horizontally, aligning the axis of the unloading hole with the axis of the mold cavity. At this point, the upper mold 42 continues to descend, pushing the crushed consumables through the unloading hole into the lower collection bucket 1, completing the automatic discharge.

[0058] Traditional crushing devices require a separate discharge valve and independent drive mechanism, resulting in complex structure and the risk of seal failure. This solution achieves simultaneous switching between mold cavity sealing and discharge channel operation through the horizontal displacement of the bottom mold 43, integrating the discharge function into the movement trajectory of the bottom mold 43, thus reducing the number of parts. This application achieves automated connection between the crushing operation and the discharge process, avoiding the risk of secondary contamination that may be caused by manual operation of the discharge valve. The reciprocating motion of the bottom mold 43 ensures the sealing requirements during crushing while quickly establishing a discharge channel, allowing the crushed consumables to completely detach from the mold cavity, solving the technical defect of poor discharge in traditional devices. This structural design makes the equipment operation process more seamless, improving the efficiency and reliability of crushing processing.

[0059] This application further proposes that the barrel cover 2 includes an upper cover 21 and a lower cover 22, which together form a device cavity. The feeding assembly 3 and the extrusion assembly 4 are both located inside the device cavity. The feeding port is located on the upper cover 21, and the bottom mold 43 is supported on the lower cover 22. The lower cover 22 has an opening corresponding to the unloading hole.

[0060] The upper cover 21 refers to the cover structure located at the top of the barrel cover 2, which can be made by stamping metal sheet. It is used to seal the top of the equipment cavity and provide a feeding port. The lower cover 22 refers to the support structure located at the bottom of the barrel cover 2, which can be made by casting aluminum with reinforcing ribs. It is used to support the bottom mold 43 and provide a discharge opening. The equipment cavity refers to the sealed space formed by the upper cover 21 and the lower cover 22, which can be made by flange connection with sealing ring. It is used to accommodate the working units of the feeding assembly 3 and the extrusion assembly 4. The opening corresponding to the discharge hole refers to the circular through hole provided in the lower cover 22. It can be made by CNC cutting. Its diameter is slightly larger than the diameter of the discharge hole of the bottom mold 43. It is used to form a directional discharge channel for consumables after crushing.

[0061] Specifically, when the upper cover 21 and the lower cover 22 are fastened together with bolts to form the equipment cavity, the spiral extension path of the feeding channel is constrained within the internal space of the equipment cavity, thus maintaining a stable consumable conveying trajectory. The bottom mold 43 is fixed to the mounting surface of the lower cover 22 by positioning pins. When the pressure drive 44 applies the clamping force, the reinforcing rib structure of the lower cover 22 can effectively disperse the impact load. After the crushing operation is completed, the bottom mold drive 45 drives the bottom mold 43 to move laterally, aligning the discharge hole with the opening of the lower cover 22. At this time, the upper mold 42 continues to descend, pushing the flattened consumable into the collection bucket 1. The sealed structure of the equipment cavity prevents external contaminants from entering the precision transmission components. At the same time, the detachable design of the upper cover 21 facilitates maintenance personnel to inspect the internal components. In traditional crushing devices, the feeding mechanism and crushing mechanism are often set separately, resulting in a large equipment size and a complex vibration transmission path. This solution, through the design of a split bucket cover 2, integrates the spiral feeding channel and the pressure drive module within the equipment cavity, shortening the transmission distance of the consumable from feeding to crushing. In existing technologies, crushed consumables often become stuck due to excessively long discharge channels. This solution, through a straight-through design of the openings of the bottom mold 43 and the lower cover 22, allows the flattened consumables to fall directly into the collection bucket 1 under gravity, avoiding secondary accumulation. This application effectively solves the operational stability problem caused by the loose internal structure of the crushing device. The rigid frame structure of the equipment cavity suppresses the transmission of vibration during crushing operations. The design of the bottom mold 43 being supported on the lower cover 22 ensures uniform distribution of pressure load, preventing structural deformation after long-term use. The correspondence between the opening of the lower cover 22 and the discharge hole ensures a smooth discharge path for the crushed consumables, avoiding equipment jamming due to poor discharge. The separate structure of the upper cover 21 and the lower cover 22 not only ensures the sealing and protection performance of the equipment cavity but also provides convenient conditions for the inspection and maintenance of internal components.

[0062] This application further proposes that the barrel lid 2 is also provided with a feed inlet cover 23, which is rotatably connected to the barrel lid 2. The feed inlet cover 23 is provided with a feed hole corresponding to the feed inlet. When the feed hole corresponds to the feed inlet, the feed inlet is open; when the feed hole is misaligned with the feed inlet, the feed inlet is closed.

[0063] The rotatable connection refers to the relative rotation between the feed inlet cover 23 and the barrel cover 2 via a rotating shaft or hinge structure. Specifically, this can be achieved using a hinge connector or a rotating shaft with a bearing structure, allowing the feed inlet cover 23 to rotate around a fixed axis in the horizontal plane. The correspondence between the feed hole and the feed inlet means that when the feed inlet cover 23 rotates to a specific angle, its through hole forms a continuous material channel with the feed inlet of the barrel cover 2. This can be achieved by setting a limiting boss or angle scale markings to ensure positioning accuracy. The misalignment between the feed hole and the feed inlet means that after the feed inlet cover 23 rotates, its solid part completely blocks the feed inlet of the barrel cover 2. This can be achieved by calculating the geometric relationship between the rotation angle of the feed inlet cover 23 and the blocking area, so that a completely sealed state is formed when the rotation angle reaches, for example, 90 degrees.

[0064] Specifically, when consumables need to be dispensed, the inlet cover 23 is rotated to a position where the inlet hole and the inlet axially align, allowing the consumables to enter the device vertically along the through-hole. After operation, the inlet cover 23 rotates a certain angle to completely cover the inlet, forming a physical barrier. This rotation is achieved manually or by a micro-motor, with a hinged connection structure maintaining the stability of the inlet cover 23 at any angle and preventing unintended rotation. In the closed state, a sealing strip can be installed between the inlet cover 23 and the barrel lid 2 to further prevent the penetration of external contaminants.

[0065] Traditional devices often employ separate cover plates or sliding baffle structures, which suffer from drawbacks such as inadequate sealing and complex operation. For example, some devices using snap-on covers require two-hand operation and are prone to accidental opening in vibrating environments. This solution achieves single-handed operation for state switching through a rotary feed inlet cover 23. The path trajectory generated by its axial rotation ensures that the sealing surface completely covers the feed inlet, while the rotation limit mechanism precisely controls the opening and closing position, preventing seal failure due to operational errors.

[0066] This application effectively solves the problem of foreign object intrusion caused by the open inlet of the vascular interventional consumable disposal device when it is not in use. When the device is idle, the rotating and closing inlet cover 23 forms a physical isolation layer, preventing dust, liquids, and other contaminants from the environment from entering the device and affecting its operation, and avoiding the risk of accidental leakage of processed consumables due to structural rebound. This mechanical sealing structure does not rely on electric or pneumatic devices and achieves reliable sealing through a simple rotation, significantly improving operational safety and equipment maintenance convenience in medical waste disposal scenarios.

[0067] This application further proposes a collection bag fitted inside a collection bucket 1, and an exhaust device is also installed on the collection bucket 1. The air inlet of the exhaust device is located inside the collection bucket 1, and the air outlet is located outside the collection bucket 1. The exhaust device is used to discharge the air between the collection bag and the collection bucket 1. The collection bag is a flexible container fitted onto the inner wall of the collection bin 1, typically made of polymer material, used to directly collect crushed and deformed consumables, preventing them from directly contacting the inner wall of the collection bin 1. The exhaust device is a device with unidirectional gas flow, such as a miniature air pump or a one-way valve, used to actively suction or passively depressurize and expel gas between the bag and the bin wall. The air inlet is a gas collection channel located on the inner wall of the collection bin 1, either at the bottom or side, used to collect residual air between the outer wall of the bag and the inner wall of the bin. The air outlet is a gas discharge channel located on the outer side of the collection bin 1, connected to the air inlet via a pipe or channel to form a gas discharge path.

[0068] After the collection bag is placed into collection container 1, the exhaust device continuously draws air from between the bag and the container wall through the air inlet, causing the bag to fit tightly against the inner wall of collection container 1 under negative pressure. During this process, the air layer between the outer wall of the bag and the inner wall of the container is completely expelled, eliminating localized expansion of the bag caused by air cushioning. When the crushed consumables fall into the collection bag, the bag's tight fit against the container wall provides rigid support, preventing the tip of the consumable from penetrating the double-layer protective structure. Simultaneously, the continuous operation of the exhaust device prevents gas expansion caused by changes in ambient temperature, thus preventing bulging and deformation of the bag due to internal air pressure variations.

[0069] Traditional medical waste collection devices typically simply place the collection bag inside a container, leaving an air gap between the bag and the container's inner wall. This makes the bag susceptible to puncture when a sharp object falls. This solution, through a dedicated venting structure, allows the collection bag to actively conform to the container's inner wall. This not only eliminates the rebound effect of the air buffer layer on sharp objects but also enhances puncture resistance through a double-layer protective structure of the bag and the container wall.

[0070] This application solves the problem of protective failure caused by residual air between the collection bag and the collection container 1. By combining physical adhesion with continuous venting, it effectively prevents the sharp parts of the crushed consumables from contacting the container, avoiding the risk of secondary contamination of medical waste. At the same time, the venting process maintains the bag's flatness, preventing the risk of bag rupture due to thermal expansion and contraction of the gas.

[0071] This application further proposes a lid 2 lock for locking the lid 2 and the collection bucket 1. The lid 2 lock is a mechanical locking component, specifically a metal latch with a rotating buckle, achieving a rigid connection through the engagement of a locking tongue and a locking groove. Locking refers to the mechanical structure that establishes a fixed connection between the lid 2 and the collection bucket 1, specifically a spring-loaded latch mechanism that generates continuous pressure when the latch is closed.

[0072] The lid 2 is locked and installed at the contact point between the opening edge of the collection bin 1 and the lid 2. When the lid 2 is closed, the locking mechanism is triggered manually or automatically, and the locking tongue engages in the locking groove on the side wall of the collection bin 1, forming a rigid fixation. During the operation of the crushing device, the vibration and pressure fluctuations generated by the crushing of the consumables in the mold cavity are absorbed by the locking structure, preventing displacement between the lid 2 and the collection bin 1. When the bottom mold 43 exits the mold cavity, the upper mold 42 pushes the crushed consumables into the collection bin 1, and the lid 2 lock maintains a sealed state, preventing debris from escaping from the connection gap. This application ensures the airtightness of the collection system during the crushing process, preventing medical waste from spilling and causing biological contamination, while also avoiding operational interruptions caused by accidental opening of the lid 2, allowing the crushed consumables to fall intact into the collection bin 1.

[0073] The working process of the vascular interventional consumable destruction device of this application is as follows: The operator first rotates the feed port cover 23 to align its feed hole with the feed port of the bucket cover 2, and then inserts the end of the vascular interventional consumable to be processed into the feed port. After the feed sensor at the feed port detects the entry of the consumable, it immediately starts the feed roller to operate, and the consumable is stably transported into the feed channel through the transmission action of the feed roller. When the front end of the consumable reaches the wire winding mechanism 5, the feed sensor in the wire winding channel 52 triggers the coordinated operation of the wire feeding assembly 51 and the winding assembly 53. The roller drive 513 of the wire feeding assembly 51 drives the wire 511 to be released directionally from the roller 512. The wire 511 is transported to the winding assembly 53 through the wire winding channel 52. The wire cutter is located at the entrance end of the channel to complete the fixed-length cutting of the wire 511. The core components of the winding assembly 53 include a winding drive 531 and a winding connector 532. The winding connector 532 is rotatably mounted on the lid 2 and driven to rotate by the winding drive 531. The feeding channel is divided into a front feeding section 31 and a rear feeding section 32. The front feeding section 31 and the twisting channel 52 both converge at the input end of the winding connector 532, while the rear feeding section 32 is connected to the output end of the winding connector 532. The winding connector 532 has two axially spaced through holes. The vascular interventional consumable passes through one through hole, and the twisted wire 511 passes through the other through hole. Driven by the winding drive 531, the winding connector 532 rotates, causing the consumable and the twisted wire 511 to intertwine and form a composite structure. The twisted material is then pushed to the rear feeding section 32.

[0074] Once the twisted consumables are fully inserted into the extrusion assembly 4, the extrusion process begins. The pressure drive 44 drives the upper die 42 and the bottom die 43 to close, applying pressure to the twisted material within the die cavity to induce irreversible plastic deformation. After extrusion, the bottom die 43 retracts, and the crushed and deformed consumables are pushed into the collection bin 1, achieving complete destruction and safe recycling of the medical consumables. This device ensures the physical destruction of vascular interventional consumables through an automated process, effectively eliminating the risk of reuse and optimizing the on-site treatment efficiency of medical waste.

[0075] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
