Description

Technical Field

[0001] This invention relates to the field of post-processing technology for intravenous puncture instruments, specifically to a post-processing device for intravenous puncture instruments. Background Technology

[0002] In makeshift hospitals, intravenous puncture instruments are routine medical tools widely used for procedures such as blood collection, infusion, and drug injection. However, intravenous puncture instruments (such as needles, catheters, and syringes) are disposable medical devices. After use, these instruments need to be collected and disposed of in a unified manner, which is directly related to the risk control of cross-infection and the management of instruments within the hospital.

[0003] A Chinese patent with publication number CN113695358B includes an instrument processing box; a sorting and recycling box located at the bottom of the instrument processing box; a hospital intravenous injection device is placed at the top of the instrument processing box, and the hospital intravenous injection device in the instrument processing box is crushed by the instrument processing box and falls into the sorting and recycling box, which contains water, and the crushed hospital intravenous injection device is separated by floating in the water in the sorting and recycling box.

[0004] When the above-mentioned device is in use, the residual medication in the medical intravenous puncture instrument is discharged through the first slag discharge channel. The crushed medical intravenous puncture instrument rolls downward through the first slag discharge channel, and during the rolling process, the medication falls from the first slag discharge channel into the first medication collection tank for collection. However, in actual use, when the crushing mechanism crushes the intravenous puncture instrument, the intravenous puncture instrument will come into contact with the patient's blood and body fluids and other pathogenic microorganisms. Moreover, the fragments of the intravenous puncture instrument contain pathogens, which can easily cause the spread of pathogens and lead to cross-infection. Therefore, it is difficult to disinfect the fragments of the intravenous puncture instrument.

[0005] Therefore, we propose a post-processing device based on venous puncture instruments. Summary of the Invention

[0006] The purpose of this invention is to provide a post-processing device for intravenous puncture instruments, which has the advantage of disinfecting fragments of intravenous puncture instruments and solves the problems in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a post-processing device for intravenous puncture instruments, comprising a processing box supported by an external bracket, wherein a feeding hopper is fixedly connected to the end of the processing box, and pulverizing rollers for pulverizing used intravenous puncture instruments are symmetrically connected to both sides of the inner wall of the feeding hopper and are fixedly rotatably connected to the pulverizing rollers. A transmission gear for meshing transmission is coaxially fixed to the same end of each of the two pulverizing rollers. One end of the pulverizing roller away from the transmission gear is driven to rotate by a power mechanism. Rectangular frames are fixedly connected to both sides of the inner wall of the processing box, and rectangular sliding rods are horizontally movably connected to the inner walls of both rectangular frames. Side plates are fixedly connected to the opposite surfaces of the two rectangular sliding rods. Multiple evenly placed movable blocks are rotatably connected to the opposite sides of the two side plates. A receiving plate is rotatably connected to the opposite surfaces of the movable blocks away from the side plates. The processing box is provided with a shaking mechanism for flattening the fragments of intravenous puncture instruments on the receiving plate and a disinfection mechanism for disinfecting the fragments of intravenous puncture instruments on the receiving plate.

[0008] Preferably, the shaking mechanism includes a bidirectional worm gear that is rotatably connected to one side of the processing box, a cylindrical block that is coaxially fixed at the center of the bidirectional worm gear, a support block that is fixedly connected to a rectangular slide rod near the cylindrical block, a guide groove that drives the receiving plate to reciprocate horizontally on the outer contour of the cylindrical block, and the end of the support block away from the rectangular slide rod that passes through the inner wall of the guide groove and is movably connected.

[0009] Preferably, a first pulley is coaxially fixed to one end of the crushing roller near the transmission gear, and a second pulley is coaxially fixed to the corresponding position of the bidirectional worm gear near the first pulley. A transmission belt that drives the bidirectional worm gear to rotate on a fixed axis is sleeved on the outer contour of the first pulley and the second pulley.

[0010] Preferably, the disinfection mechanism includes two rectangular frames with disinfection boxes for storing disinfectant fixedly connected at symmetrical positions at both ends of opposite sides. The inner wall of each rectangular frame is fixedly connected to a cylindrical tube that communicates with the disinfection boxes at both ends. A rectangular slide rod is movably connected through the cylindrical tube. A cavity is opened on both sides of the rectangular slide rod. A piston plate that moves horizontally on the inner wall of the cavity is fixedly connected to the outer contour of the cylindrical tube.

[0011] Preferably, each of the rectangular slide rods on each side has a drain pipe that extends through to the inner wall and is fixedly connected at symmetrical positions near both ends of the cavity. Atomizing nozzles for spraying disinfectant onto the material plate are fixedly connected at symmetrical positions on the top sides of the two rectangular frames. The ends of the two drain pipes on each side away from the rectangular slide rods extend through to the inner wall of the atomizing nozzle on the adjacent side and are fixedly connected. Each cylindrical tube has a one-way inlet valve for quantitatively extracting disinfectant from the disinfection chamber at symmetrical positions near both sides of the piston plate. Each drain pipe has a one-way outlet valve for quantitatively discharging disinfectant from the cavity onto the inner wall near the end of the rectangular slide rod.

[0012] Preferably, both ends of the rectangular frame are rotatably connected by pins to cylindrical magnetic blocks that separate needle fragments and plastic fragments from the material plate. The ends of the two cylindrical magnetic blocks near the cylindrical magnetic blocks are coaxially fixed to worm wheels that mesh with bidirectional worm gears for transmission. Both ends of the rectangular frame are fixedly connected to scrapers for cleaning needle fragments adsorbed on the surface of the cylindrical magnetic blocks, and the scrapers are in contact with and movably connected to the outer contour of the cylindrical magnetic blocks.

[0013] Preferably, the processing box is symmetrically connected to guide hoppers for feeding needle fragments at both sides, and collection boxes for collecting needle fragments are symmetrically connected to both sides of the processing box near the bottom of the guide hoppers. The bottom of the processing box is symmetrically connected to discharge hoppers for centralized feeding plastic fragments at both sides.

[0014] Preferably, the rectangular frame is provided with a vibration mechanism that bounces the fragments of the venipuncture instrument on the surface of the receiving plate. The vibration mechanism includes a first protrusion fixedly connected to the bottom side of both sides of the rectangular frame to push the receiving plate upward, and a plurality of evenly placed second protrusions fixedly connected to the bottom of the receiving plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] I. By combining a pulverizing roller with a drive gear, efficient pulverization of used intravenous puncture instruments can be achieved. Driven by a motor and driven by the gear, the pulverizing roller can evenly crush the intravenous puncture instruments, thoroughly pulverizing all parts of the instruments (such as metal needles and plastic shells). This reduces cross-contamination that may occur during manual handling. Furthermore, the resulting fragments are guided to a receiving plate for further processing, ensuring both efficiency and safety in the process.

[0017] Second, the design of the bidirectional worm gear and guide groove drives the receiving plate to reciprocate horizontally, ensuring that the fragments of intravenous puncture instruments are evenly spread on the surface of the receiving plate. This improves the uniformity of disinfectant spraying. The disinfectant is evenly sprayed onto the spread fragment surface through the atomizing nozzle, ensuring that each fragment is fully disinfected. This effectively reduces the retention of pathogens in the fragments, lowers the risk of cross-infection during medical waste disposal, and meets high standards for medical waste disposal.

[0018] Third, the cylindrical magnetic block is rotated by a bidirectional worm gear and worm wheel to uniformly adsorb and separate needle fragments on the receiving plate. The worm wheel then guides the needle fragments to a designated position, allowing the scraper to remove the needle fragments adsorbed on the surface of the cylindrical magnetic block. The needle fragments fall onto the surface of the guide hopper, which then guides them to the inner wall of the collection box for centralized collection. Meanwhile, plastic fragments fall uniformly through both ends of the receiving plate and enter the discharge hopper for discharge. This separation process not only efficiently and accurately separates two different types of waste but also improves the recycling efficiency of waste, avoids the mixing of needle fragments and plastic fragments, and facilitates subsequent classification and reuse. This design effectively enhances the systematicness and standardization of waste treatment.

[0019] Fourth, through the synergistic effect of the first and second protrusions on the receiving plate, the receiving plate can reciprocate and vibrate. The vibration process not only enhances the contact between the fragments and the magnetic blocks, but also makes the flattened fragments evenly distributed on the surface of the receiving plate, effectively improving the separation accuracy and processing efficiency.

[0020] The combined use of the above structures solves the problem that in the actual use of existing devices, when the pulverizing mechanism pulverizes the venous puncture instruments, the venous puncture instruments come into contact with the patient's blood, body fluids, and other pathogens, and the fragments of the venous puncture instruments contain pathogens, which can easily cause the spread of pathogens and lead to cross-infection. Therefore, it is difficult to disinfect the fragments of the venous puncture instruments. Attached Figure Description

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1:

[0034] Please see Figures 1 to 10This invention provides a technical solution: a post-processing device for intravenous puncture instruments, comprising a processing box 1 supported by an external bracket. A feed hopper 2 is connected and fixedly connected to one end of the processing box 1. Crushing rollers 3 for crushing used intravenous puncture instruments are symmetrically connected to both sides of the inner wall of the feed hopper 2, and are rotatably connected to each roller. A transmission gear 4 for meshing transmission is coaxially fixed to the same end of each crushing roller 3. One end of the crushing roller 3 away from the transmission gear 4 is driven to rotate by a power mechanism. The processing box 1 contains… Rectangular frames 5 are fixedly connected to symmetrical positions on both sides of the wall. Rectangular slide rods 6 are horizontally movably connected to the inner walls of the two rectangular frames 5. Side plates 7 are fixedly connected to the opposite surfaces of the rectangular slide rods 6 on both sides. Multiple evenly placed movable blocks 8 are rotatably connected to the opposite sides of the side plates 7 on both sides. A receiving plate 9 is rotatably connected to the opposite surfaces of the movable blocks 8 on both sides away from the side plates 7. The processing box 1 is equipped with a shaking mechanism for flattening the fragments of venipuncture instruments on the receiving plate 9 and a disinfection mechanism for disinfecting the fragments of venipuncture instruments on the receiving plate 9.

[0035] In use, a processing box 1 is set up and placed on the ground with an external bracket to ensure the stability of the processing device. The feeding hopper 2 is set on the processing box 1 and is fixedly supported on the processing box 1, so that the feeding hopper 2 is connected to the inner wall of the processing box 1. The crushing roller 3 is set on the feeding hopper 2 and is connected to the fixed axis for rotation. First, the used intravenous puncture instrument is placed on the crushing roller 3 inside the feeding hopper 2. The transmission gear 4 set on the crushing roller 3, one of which is driven by a motor, can make the crushing roller 3 rotate relative to the motor, so that the crushing roller 3 can crush the used intravenous puncture instrument inside the feeding hopper 2.

[0036] The rectangular frame 5 on the processing box 1 is fixedly supported on the inner wall of the processing box 1. The rectangular slide rod 6 on the rectangular frame 5 and the side plate 7 on the rectangular slide rod 6 are fixedly supported on the rectangular slide rod 6, so that the rectangular slide rod 6 can drive the side plate 7 to move horizontally on the inner wall of the rectangular slide rod 6. The movable block 8 on the side plate 7 and the receiving plate 9 on the movable block 8 can make the movable block 8 rotate and support the receiving plate 9 on the side plate 7. At the same time, the feed hopper 2 can guide the fragments of intravenous puncture instruments pulverized by the crushing roller 3 to be discharged onto the surface of the receiving plate 9. The shaking mechanism and the disinfection mechanism on the processing box 1 can cause the receiving plate 9 to shake horizontally back and forth to flatten the fragments of intravenous puncture instruments on the surface. At the same time, the disinfection mechanism sprays disinfectant on the flattened fragments of intravenous puncture instruments on the surface of the receiving plate 9.

[0037] Example 2:

[0038] Building upon Example 1, the following is a further step:

[0039] The shaking mechanism includes a bidirectional worm gear 10 that is rotatably connected to one side of the processing box 1. A cylindrical block 11 is coaxially fixed at the center of the bidirectional worm gear 10. A support block 12 is fixedly connected to a rectangular slide rod 6 near the cylindrical block 11. A guide groove 111 is provided on the outer contour of the cylindrical block 11 to drive the receiving plate 9 to reciprocate horizontally. The end of the support block 12 away from the rectangular slide rod 6 passes through the inner wall of the guide groove 111 and is movably connected.

[0040] The crushing roller 3 is coaxially fixed to one end near the transmission gear 4 with a first pulley 14, and the bidirectional worm gear 10 is coaxially fixed to the corresponding position near the first pulley 14 with a second pulley 16. The outer contours of the first pulley 14 and the second pulley 16 are fitted with a transmission belt 15 that drives the bidirectional worm gear 10 to rotate on a fixed axis.

[0041] In use, the bidirectional worm gear 10 installed on the processing box 1 allows the bidirectional worm gear 10 to rotate on the processing box 1 in a fixed axis. The second pulley 16 installed on the bidirectional worm gear 10 and the first pulley 14 installed on the crushing roller 3 are coaxially fixed to the bidirectional worm gear 10 and the crushing roller 3, respectively. The transmission belt 15 installed on the first pulley 14 and the second pulley 16 rotates in a fixed axis along with the crushing roller 3. Thus, under the action of the crushing roller 3, the first pulley 14 can drive the second pulley 16 and the bidirectional worm gear 10 to rotate synchronously in a fixed axis through the transmission belt 15.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the cylindrical block 11 on the bidirectional worm gear 10 can rotate synchronously with the bidirectional worm gear 10. The guide groove 111 on the cylindrical block 11 and the support block 12 on the rectangular slide rod 6 allow the guide groove 111 to support the support block 12 on the inner wall. As the cylindrical block 11 rotates, the support block 12 drives the rectangular slide rod 6 to move horizontally back and forth along the inner wall of the rectangular frame 5 under the action of the guide groove 111. The side plate 7 can drive the receiving plate 9 to shake back and forth, which allows the receiving plate 9 to shake and flatten the intravenous puncture instrument fragments on the surface towards both ends, so as to facilitate the subsequent comprehensive disinfection of the intravenous puncture instrument fragments on the surface of the receiving plate 9. At the same time, the reciprocating shaking of the receiving plate 9 can make the intravenous puncture instrument fragments on the surface fall down from both ends at a uniform speed.

[0043] Example 3:

[0044] Building upon Example 2, the following is a further step:

[0045] The disinfection mechanism includes two rectangular frames 5 with disinfection tanks 17 for storing disinfectant fixedly connected at symmetrical positions at both ends of opposite sides. The inner wall of each rectangular frame 5 is fixedly connected to a cylindrical tube 18 that communicates with the disinfection tanks 17 at both ends. A rectangular slide rod 6 is movably connected through the cylindrical tube 18. A cavity 601 is opened on both sides of the rectangular slide rod 6. A piston plate 19 that moves horizontally on the inner wall of the cavity 601 is fixedly connected to the outer contour of the cylindrical tube 18.

[0046] Each rectangular slide bar 6 on each side has a drain pipe 20 that extends through to the inner wall and is fixedly connected to the symmetrical positions near both ends of the cavity 601. Atomizing nozzles 21 for spraying disinfectant on the docking plate 9 are fixedly connected to the symmetrical positions on the top sides of the two rectangular frames 5. The ends of the two drain pipes 20 on each side away from the rectangular slide bar 6 extend through to the inner wall of the atomizing nozzle 21 on the adjacent side and are fixedly connected. Each cylindrical tube 18 is connected to a one-way inlet valve 181 for quantitatively extracting disinfectant from the inside of the disinfection box 17 at symmetrical positions near both sides of the piston plate 19. Each drain pipe 20 has a one-way drain valve 201 for quantitatively discharging disinfectant from the inside of the cavity 601 that is fixedly connected to the inner wall near the end of the rectangular slide bar 6.

[0047] In use, the disinfection box 17 is fixedly supported on the rectangular frame 5. First, the disinfectant is stored inside the disinfection box 17. The cylindrical tube 18 on the transmission belt 15 is connected to the inside of the disinfection box 17. Through the cavity 601 opened on the rectangular slide rod 6, and the cavity 601 on the cylindrical tube 18 moves horizontally back and forth with the rectangular slide rod 6, the piston plate 19 can move horizontally back and forth synchronously on the inner wall of the cavity 601.

[0048] like Figures 6 to 10As shown, the drain pipe 20 on the rectangular slide bar 6 and the atomizing nozzle 21 on the rectangular frame 5 enable the drain pipe 20 to connect the atomizing nozzle 21 to the inner wall of the cavity 601. When the piston plate 19 moves toward one end of the cavity 601, the internal air pressure at one end of the cavity 601 becomes positive, and the internal air pressure at the other end becomes negative. Through the one-way inlet valve 181 on the cylindrical tube 18 and the one-way drain valve 201 on the drain pipe 20, the one-way inlet at one end... With the liquid valve 181 closed and the one-way drain valve 201 open, the drain pipe 20 can discharge the internal disinfectant from one end of the cavity 601 into the atomizing nozzle 21. At the same time, the atomizing nozzle 21 can evenly spray the disinfectant onto the fragments of the intravenous puncture instrument on the surface of the receiving plate 9 for disinfection. Meanwhile, with the one-way inlet valve 181 open and the one-way drain valve 201 closed at the other end, the columnar tube 18 can draw the disinfectant from inside the disinfection box 17 to the other end of the cavity 601.

[0049] When the piston plate 19 moves toward the other end of the cavity 601, it moves in the opposite direction to the structure described above. As a result, the atomizing nozzle 21 can continuously spray disinfectant onto the surface of the venous puncture instrument fragments on the material plate 9, ensuring the continuity of disinfectant spraying, improving the disinfection effect on the venous puncture instrument fragments, and avoiding the risk of secondary transmission caused by bacteria, viruses and other pathogens carried by the venous puncture instrument fragments due to personnel contact.

[0050] Example 4:

[0051] Building upon Example 3, the following is a further step:

[0052] Both ends of the rectangular frame 5 are rotatably connected by pins to cylindrical magnetic blocks 22 that separate needle fragments and plastic fragments on the docking plate 9. The ends of the two cylindrical magnetic blocks 22 near the cylindrical magnetic blocks 22 are coaxially fixed to worm gears 23 that mesh with the bidirectional worm gear 10 for transmission. Both ends of the rectangular frame 5 are fixedly connected to scrapers 24 for cleaning needle fragments adsorbed on the surface of the cylindrical magnetic blocks 22, and the scrapers 24 are in contact with and movably connected to the outer contour of the cylindrical magnetic blocks 22.

[0053] Both sides of the processing box 1 are symmetrically connected to guide hoppers 25 for feeding needle fragments, and both sides of the processing box 1 are symmetrically connected to collection boxes 26 for collecting needle fragments. Both sides of the bottom of the processing box 1 are symmetrically connected to discharge hoppers 29 for guiding plastic fragments to be discharged in a concentrated manner.

[0054] In use, the cylindrical magnetic blocks 22 set on the rectangular frame 5 are connected to rotate on a fixed axis on the rectangular frame 5. The worm gear 23 set on the cylindrical magnetic blocks 22 meshes with the bidirectional worm gear 10. As the bidirectional worm gear 10 rotates on a fixed axis, the worm gear 23 can drive the cylindrical magnetic blocks 22 at both ends to rotate synchronously under the action of the bidirectional worm gear 10. At the same time, the receiving plate 9 shakes the intravenous puncture instrument fragments at both ends to feed them at a uniform speed. Thus, under the action of magnetic force, the cylindrical magnetic blocks 22 can evenly attract the needle fragments at both ends of the receiving plate 9 to the surface. At the same time, the plastic fragments in the intravenous puncture instrument fragments fall from both ends of the receiving plate 9 at a uniform speed, realizing the separation of needle fragments and plastic fragments in the intravenous puncture instrument fragments, and further improving the efficiency of processing intravenous puncture instruments.

[0055] The scraper 24 on the rectangular frame 5 is fixedly supported on the rectangular frame 5 and is in contact with the surface of the cylindrical magnetic block 22. As the cylindrical magnetic block 22 rotates, it adsorbs and separates the needle fragments, allowing the scraper 24 to hang the needle fragments adsorbed on the surface of the cylindrical magnetic block 22. The needle fragments hanging by the scraper 24 fall onto the surface of the scraper 25 through the guide hopper 25 and the collection box 26 on the processing box 1. The guide hopper 25 is located at the bottom of the scraper 24, and the guide hopper 25 is placed at an angle, so that the guide hopper 25 can guide the needle fragments to the inner wall of the collection box 26 for centralized collection. The discharge hopper 29 on the processing box 1 is located at both ends of the receiving plate 9, and the discharge hopper 29 can discharge the separated fragments in a centralized manner, so that the medical staff can separate the separated plastic fragments and needle fragments for further processing, which further improves the efficiency of processing intravenous puncture instruments.

[0056] Example 5:

[0057] Building upon Example 4, the following is a further step:

[0058] The rectangular frame 5 is provided with a vibration mechanism that bounces the fragments of the venipuncture instrument on the surface of the receiving plate 9. The vibration mechanism includes a first protrusion 27 fixedly connected to the bottom side of both sides of the rectangular frame 5 to push the receiving plate 9 upward, and a plurality of evenly placed second protrusions 28 fixedly connected to the bottom of the receiving plate 9.

[0059] When using, such as Figure 3 and Figure 4As shown, the first protrusion 27 is fixedly supported on the rectangular frame 5 by the first protrusion 27. The second protrusion 28 is provided on the receiving plate 9 so that the second protrusion 28 corresponds to the first protrusion 27. The movable block 8 is rotatably connected to the receiving plate 9. As the receiving plate 9 swings horizontally, the movable block 8 can drive the receiving plate 9 to vibrate back and forth under the action of the first protrusion 27 and the second protrusion 28. This allows the receiving plate 9 to lift the intravenous puncture instrument fragments on its surface upwards. The lifted intravenous puncture instrument fragments come into contact with the cylindrical magnetic block 22, further improving the separation effect of the cylindrical magnetic block 22 on the needle fragments.

[0060] Furthermore, the existing device can disinfect fragments of intravenous puncture instruments during actual use, making it convenient to use and superior to traditional products.

[0061] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed directly based on existing technical knowledge without any doubt. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0062] 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.
