Description
Technical Field
[0001] The present invention relates to the technical field of centralized processing of medical equipment, and in particular to a centralized processing device for medical equipment. Background Art
[0002] As a temporary medical treatment facility, Fangcang Hospital was quickly put into use and played an important role. Fangcang Hospital is usually built in a short period of time, with the characteristics of rapid deployment and flexible configuration, and can quickly accommodate a large number of patients. However, Fangcang Hospital faces the problem of centralized processing of used medical equipment during operation. At present, people collect the medical equipment that needs to be processed in a unified manner, and then transport and process them. The general processing methods are incineration and landfill. However, before incineration or landfill, the medical equipment needs to be crushed to improve processing efficiency. In addition, the processing of medical equipment mostly relies on manual operation, which is not only inefficient but also prone to errors.
[0003] The existing Chinese patent with publication number CN114378095B includes a partition, a control panel, a liquid level sensor, a first support frame, a placement frame, a crusher, a material transport mechanism, a crushing mechanism, a feeding mechanism and a cooling mechanism. A control panel is provided on the left front side of the partition, a liquid level sensor is provided on the left rear side of the bottom inner side of the partition, a first support frame is provided on the left top side of the partition, a placement frame is provided on the top of the first support frame, a material transport mechanism is provided on the placement frame, a crushing mechanism is provided on the right upper part of the first support frame, a crusher for crushing medical equipment is rotatably provided on the crushing mechanism, a feeding mechanism is provided on the right top side of the partition, and a cooling mechanism is provided on the top of the first support frame.
[0004] When the above device is in use, the first reduction motor is used as the driving force to drive the first conveyor belt to rotate. The first conveyor belt can transfer the medical equipment to the right to the crushing frame, and then the crusher is rotated to crush the medical equipment. Then, the water pump is used as the driving force to spray the water in the partition into the crushing frame to achieve a cooling effect. However, in actual use, since some syringes have disposable syringe needles made of ferritic stainless steel, after the crusher crushes the medical equipment, the plastic and the needle are mixed together, and the chemical materials of the needle fragments and the plastic fragments are different, which increases the difficulty of subsequent incineration and landfill of the medical equipment. Therefore, it is difficult to separate the crushed needle fragments and plastic fragments.
[0005] To this end, we propose a centralized processing device for medical equipment. Summary of the Invention

[0012] Preferably, guide plates for guiding the discharge of needle fragments from the magnet plate are penetrated and fixedly connected at symmetrical positions on both sides of the processing box. One end of the guide plate on each side close to the magnet plate is in contact with and movably connected to the surface of the cylindrical roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] First, the transmission gear drives the pulverizing rollers to rotate relative to each other, allowing them to crush used medical equipment in the pulverizing frame, effectively breaking down both hard and soft materials, such as iron needles and plastic tubes, into smaller fragments. These smaller fragments are not only easier to separate, but also provide a better foundation for subsequent material recycling, thereby improving overall waste treatment efficiency.
[0018] 2. As the crushing roller crushes the medical equipment, it can drive the bidirectional worm and the cylindrical block to rotate, so that the moving block can pull the receiving plate to swing back and forth horizontally, flattening the medical equipment fragments on the receiving plate to both ends to avoid accumulation, so as to facilitate the subsequent separation of needle fragments and plastic fragments from the medical equipment fragments on the surface of the receiving plate.
[0019] 3. With the rotation of the bidirectional worm, the worm wheel can drive the cylindrical roller to rotate on a fixed axis, and the magnet plate arranged on the cylindrical roller can quickly absorb and separate the needle fragments mixed in the plastic fragments according to the different physical properties of the needle fragments and the plastic fragments. The magnet plate can telescope on the cylindrical roller and discharge the needle fragments separated from the surface of the magnet plate, thereby improving the processing efficiency and avoiding the pollution or waste of resources caused by the mixing of different materials in the subsequent processing links, thereby increasing the processing cost.
[0020] 4. As the receiving plate swings back and forth horizontally, the U-shaped frame drives the knocking block to knock on the bottom of the receiving plate through the cooperation of the protrusion and the spring, and the mixed medical device fragments on the receiving plate are thrown upward, and the thrown medical device fragments come into contact with the magnet plate, further improving the magnet plate's separation effect on needle fragments and plastic fragments in the medical device fragments, and can separate different materials more accurately to ensure the purity of each material, thereby improving the efficiency of subsequent processing and reducing the cost and difficulty of mixed processing of different materials.
[0021] The above-mentioned structure solves the problem that, in actual use of the existing device, due to the presence of an iron needle on the infusion tube, the crusher causes plastic and iron to mix together after crushing the medical equipment. In addition, the needle fragments and the plastic fragments have different chemical materials, which increases the difficulty of subsequent incineration and landfill of the medical equipment, making it difficult to separate the crushed needle fragments and plastic fragments.

Then, the moving block 10 can drive the receiving plate 7 to swing back and forth horizontally on the track plate 6 under the action of the guide groove 901, and the receiving plate 7 can flatten the medical equipment fragments toward both ends and discharge them at a uniform speed, so as to facilitate the subsequent separation of needle fragments in the medical equipment fragments.
[0041] Example 3:
[0042] On the basis of the second embodiment, further steps are as follows:
[0043] The separation mechanism includes two support blocks 14 fixedly connected at symmetrical positions at both ends of the two track plates 6, and a circular plate 15 is penetrated and fixedly connected to the corresponding position of each support block 14. The opposite surfaces of the two circular plates 15 on each side are penetrated and connected with a cylindrical roller 16 for fixed axis rotation. The ends of the cylindrical rollers 16 on both sides close to the cylindrical block 9 are coaxially fixedly connected with a worm gear 17 that meshes with the bidirectional worm 8 for transmission.
[0044] A plurality of evenly arranged movable grooves 161 are provided on the outer contour of each of the cylindrical rollers 16, and the inner wall of each movable groove 161 is telescopically connected to a magnet plate 18 for adsorbing and separating needle fragments. Movable blocks 19 are fixedly connected to symmetrical positions at both ends of each magnet plate 18, and cam grooves 151 for driving the magnet plate 18 to telescopically move are provided on the opposite surfaces of the two circular plates 15 at each end. Each movable block 19 is connected to the inner wall of the cam groove 151 on the adjacent side away from the magnet plate 18 and is movably connected.
[0045] When in use, through the support block 14 set on the track plate 6 and the circular plate 15 set on the support block 14, the support block 14 can fix the circular plate 15 on the track plate 6, and through the cylindrical roller 16 set on the circular plate 15, the cylindrical roller 16 is rotatably supported on the circular plate 15, and through the worm gear 17 set on the cylindrical roller 16, and the worm gear 17 is engaged with the bidirectional worm 8 for transmission, the bidirectional worm 8 rotates around the fixed axis, and the worm gear 17 can drive the cylindrical roller 16 to rotate around the fixed axis under the action of the bidirectional worm 8.
[0046] Through the movable groove 161 opened on the cylindrical roller 16 and the magnet plate 18 provided on the movable groove 161, the movable groove 161 can limit the moving direction of the magnet plate 18. Through the cam groove 151 opened on the circular plate 15 and the movable block 19 provided on the magnet plate 18, the cam groove 151 can support the movable block 19. As the cylindrical roller 16 rotates around a fixed axis, the movable block 19 can pull the magnet plate 18 to move back and forth along the inner wall of the movable groove 161 under the action of the cam groove 151.
[0047] like Figure 1 、 Figure 2 and Figure 7 As shown, when the cylindrical roller 16 drives the magnet plate 18 to rotate toward the bottom side, the movable block 19 pushes the magnet plate 18 to extend out of the inner wall of the movable groove 161 under the action of the cam groove 151, and the magnet plate 18 extends to the upper side of the receiving plate 7, so that the magnet plate 18 can adsorb the needle fragments in the medical equipment fragments on the receiving plate 7 on the surface under the action of magnetic force. When the cylindrical roller 16 drives the magnet plate 18 to rotate toward the top side, the movable block 19 can pull the magnet plate 18 to retract to the inner wall of the movable groove 161 under the action of the cam groove 151, and the magnet plate 18 fits the inner wall of the movable groove 161. As the magnet plate 18 retracts and moves toward the inner wall of the movable groove 161, the movable groove 161 can scrape off the needle fragments adsorbed on the surface of the magnet plate 18, so as to facilitate the subsequent centralized collection of the separated needle fragments.
[0048] The above structure is aimed at disposable syringe needles made of ferritic stainless steel, and ferritic stainless steel has strong magnetism, so the needles can be recycled and processed by utilizing its magnetism.
[0049] Example 4:
[0050] On the basis of the third embodiment, further steps are as follows:
[0051] The processing box 1 is symmetrically positioned on both sides and is fixedly connected with guide plates 20 for guiding the needle fragments on the magnet plate 18 to be discharged. The end of the guide plate 20 on each side close to the magnet plate 18 is in contact with the surface of the cylindrical roller 16 and is movably connected. Both ends of the processing box 1 are fixedly connected near the bottom side of the guide plate 20 with a collection box 21 for centrally collecting the needle fragments.
[0052] When in use, the guide plate 20 is fixedly supported on the processing box 1 by the guide plate 20 provided on the processing box 1, and the opposite ends of the two guide plates 20 are respectively in contact with the surface of the cylindrical roller 16 on the adjacent side, and the movable groove 161 scrapes off the needle fragments adsorbed on the surface of the magnet plate 18, so that the needle fragments can fall on the surface of the guide plate 20. When the magnet plate 18 moves to the extreme position of the inner wall of the movable groove 161, the outer side of the magnet plate 18 and the outer contour of the spring 26 are adapted to each other, so that the guide plate 20 can scrape off the needle fragments adsorbed on the outer side of the magnet plate 18, and the collection box 21 provided on the processing box 1 is fixedly supported on the bottom of the guide plate 20, and the guide plate 20 is placed obliquely, so that the guide plate 20 can guide the needle fragments to be discharged into the interior of the collection box 21 for centralized collection, and the collection box 21 is detachably connected to the processing box 1, so that subsequent personnel can remove the collection box 21 for centralized processing of the needle fragments.
[0053] Embodiment 5:
[0054] On the basis of the fourth embodiment, further steps are as follows:
[0055] The track plate 6 is provided with a knocking mechanism for throwing up the medical equipment fragments on the receiving plate 7. The knocking mechanism includes fixed blocks 22 fixedly connected to symmetrical positions at both ends of each track plate 6, and a U-shaped frame 23 is penetrated and connected to the two fixed blocks 22 on each side for lifting and moving. The two U-shaped frames 23 are fixedly connected with knocking blocks 24 for knocking the bottom of the receiving plate 7.
[0056] Each of the two ends of the U-shaped frame 23 is fixedly connected to a conical block 25, and each of the conical blocks 25 is fixedly connected to the opposite surface of the fixed block 22 with a spring 26 that guides the knocking block 24 to reset and move. Two protrusions 27 that push the knocking block 24 to move are fixedly connected at symmetrical positions on both sides of the material receiving plate 7.

The conical block 25 provided on the fixed block 22 and the spring 26 provided on the conical block 25 can support the position of the knocking block 24 under the elastic force of the cylindrical roller 16. The protrusion 27 provided on the material receiving plate 7 can drive the protrusion 27 to move back and forth horizontally.
[0058] like Figure 3 、 Figure 5 、 Figure 8 As shown, when the receiving plate 7 drives the protrusion 27 to contact and move with the conical block 25, the conical block 25 moves in the vertical direction close to the fixed block 22 under the action of the protrusion 27. At the same time, the U-shaped frame 23 drives the knocking block 24 to move downward under the action of the conical block 25 and disengage from the bottom of the receiving plate 7, and the spring 26 is squeezed and contracted under the action of the conical block 25. As the protrusion 27 moves and disengages from the conical block 25, the conical block 25 can pull the U-shaped frame 23 and the knocking block 24 quickly in the upward vertical direction to reset, so that the knocking block 24 can knock the bottom of the receiving plate 7, and the medical equipment fragments on the receiving plate 7 are thrown upward under the action of knocking, and the thrown medical equipment fragments contact the magnet plate 18, further improving the separation effect of the magnet plate 18 on the needle fragments and plastic fragments in the medical equipment fragments.
[0059] Example 6:

[0061] The bottom of the processing box 1 is penetrated and fixedly connected with a lower hopper 29 for centralized discharge of plastic fragments, and inclined plates 28 for guiding the crushed fragments to the lower hopper 29 are fixedly connected at symmetrical positions on both sides of the inner wall of the processing box 1 near the bottom.
[0062] During use, the lower hopper 29 provided on the processing box 1 is fixedly supported on the processing box 1, so that the lower hopper 29 is connected with the inside of the processing box 1, and the inclined plate 28 provided on the processing box 1 is placed obliquely on the inner wall of the processing box 1. As the receiving plate 7 rotates horizontally back and forth, the plastic fragments separated on the surface of the receiving plate 7 can move toward the two ends at a uniform speed under the action of inertia, and the plastic fragments on the receiving plate 7 fall from the two ends at a uniform speed, so that the inclined plate 28 can guide the plastic fragments to the lower hopper 29 for centralized discharge, so that personnel can collect the separated plastic fragments in a centralized manner.
[0063] Furthermore, the existing device can separate the crushed needle fragments and plastic fragments during actual use, is easy to use, and is better than traditional products.
[0064] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and drawings can also be directly processed according to existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so no specific description will be given here.
[0065] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
