Description

Technical Field

[0001] The present invention relates to the technical field of post-processing for venous puncture instruments, and in particular to a post-processing device for venous puncture instruments. Background Art

[0002] In Fangcang Cabin Hospital, intravenous puncture instruments are routine medical tools and are widely used in patients' venous blood collection, infusion, drug injection and other operations. However, intravenous puncture instruments (such as needles, catheters, syringes, etc.) are disposable medical devices. After use, intravenous puncture instruments need to be uniformly recycled and processed, which is directly related to the risk control of cross-infection and the internal equipment management of the hospital.

[0003] The existing Chinese patent with publication number CN113695358B includes an instrument processing box; a classification recovery box, which is arranged at the bottom of the instrument processing box; hospital intravenous injection instruments are placed on the top of the instrument processing box, and the hospital intravenous injection instruments in the instrument processing box are crushed by the instrument processing box and fall into the classification recovery box, and water is stored in the classification recovery box, and the crushed hospital intravenous injection instruments are separated by floating in the water in the classification recovery box.

[0004] When the above-mentioned device is in use, the residual medicine liquid in the medical intravenous puncture instrument is discharged through the first slag discharge channel, and the crushed medical intravenous puncture instrument rolls downward from the first slag discharge channel. During the rolling process, the medicine liquid drops downward from the first slag discharge channel to the first medicine collection box 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, body fluids and other pathogenic microorganisms, and 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.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By combining the crushing roller with the transmission gear, the used intravenous puncture instruments can be efficiently crushed. Driven by the motor, the crushing roller can evenly crush the intravenous puncture instruments through the transmission of the transmission gear, so that all parts of the instrument (such as metal needles, plastic shells, etc.) are completely crushed, reducing the cross contamination that may be caused by manual handling. In addition, the fragments produced after crushing are guided to the receiving plate for further processing, ensuring the efficiency and safety of the processing process.

[0017] 2. Through the design of bidirectional worm and guide groove, the receiving plate is driven to shake horizontally back and forth, ensuring that the fragments of intravenous puncture instruments are evenly flattened on the surface of the receiving plate, thereby improving the uniformity of disinfectant spraying. The disinfectant is evenly sprayed on the flattened surface of the fragments through the atomizing nozzle, ensuring that each fragment can be fully disinfected. This effectively reduces the retention of pathogens in the fragments and reduces the risk of cross-infection during the treatment of medical waste, meeting the high standards of medical waste treatment.

[0018] 3. The bidirectional worm and worm gear drive the cylindrical magnetic block to rotate to evenly adsorb and separate the needle fragments on the receiving plate, and guide them to the specified position through the transmission of the worm gear, so that the scraper can hang the needle fragments adsorbed on the surface of the cylindrical magnetic block, and the needle fragments fall on the surface of the guide hopper, and then the guide hopper can guide the needle fragments to the inner wall of the collection box for centralized collection, while the plastic fragments fall at a uniform speed through the two ends of the receiving plate and enter the lower hopper for discharge. This separation process not only efficiently and accurately separates the waste of two different materials, but also improves the waste recovery efficiency, avoids the mixing of needles and plastic fragments, and facilitates subsequent classification and reuse. This design effectively improves the systematic and standardized level of waste treatment.

[0019] Fourth, through the synergistic effect of the first protrusion and the second protrusion on the receiving plate, the receiving plate can vibrate back and forth. The vibration process not only enhances the contact between the fragments and the magnetic block, 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 coordinated use of the above-mentioned structure solves the problem that, in the actual use of the existing device, when the crushing mechanism crushes the intravenous puncture instrument, the intravenous puncture instrument will come into contact with the patient's blood, body fluids and other pathogenic microorganisms, and pathogens may exist on the intravenous puncture instrument fragments, which may easily cause the spread of pathogens and lead to cross infection, making it difficult to disinfect the intravenous puncture instrument fragments.

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

[0041] When in use, the bidirectional worm 10 provided on the processing box 1 is connected to the processing box 1 for fixed-axis rotation. Through the second pulley 16 provided on the bidirectional worm 10 and the first pulley 14 provided on the crushing roller 3, the second pulley 16 and the first pulley 14 are coaxially fixedly connected to the bidirectional worm 10 and the crushing roller 3 respectively. Through the transmission belt 15 provided on the first pulley 14 and the second pulley 16, the crushing roller 3 is rotated along with the fixed-axis rotation. Therefore, under the action of the crushing roller 3, the first pulley 14 can drive the second pulley 16 and the bidirectional worm 10 to rotate synchronously with the fixed-axis rotation through the transmission belt 15.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, by the cylindrical block 11 arranged on the bidirectional worm 10, the cylindrical block 11 can be synchronously rotated along with the bidirectional worm 10 on a fixed axis, and through the guide groove 111 opened in the cylindrical block 11 and the support block 12 arranged on the rectangular slide bar 6, the guide groove 111 can movably support the support block 12 on the inner wall, and the cylindrical block 11 rotates along a fixed axis, and then the support block 12 drives the rectangular slide bar 6 to move horizontally back and forth along the inner wall of the rectangular frame 5 under the action of the guide groove 111, and the side plate 7 can drive the receiving plate 9 to rock back and forth, so that the receiving plate 9 can rock and flatten the intravenous puncture instrument fragments on the surface toward both ends, so as to facilitate the subsequent comprehensive disinfection of the intravenous puncture instrument fragments on the surface of the receiving plate 9, and at the same time, the reciprocating rocking of the receiving plate 9 can make the intravenous puncture instrument fragments on the surface fall from both ends at a uniform speed.

[0043] Embodiment three:

[0044] On the basis of the second embodiment, further:

[0045] The disinfection mechanism includes two rectangular frames 5, both ends of which are symmetrically connected to disinfection boxes 17 for storing disinfectant. The inner wall of each rectangular frame 5 is fixedly connected to a cylindrical tube 18 that is connected to the disinfection boxes 17 at both ends, and the rectangular slide rod 6 is penetrated by the cylindrical tube 18 and movably connected. A cavity 601 is opened on the rectangular slide rod 6 on both sides, and 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] The rectangular slide bar 6 on each side is symmetrically positioned near both ends of the cavity 601, and is penetrated to the inner wall and fixedly connected with a drainage pipe 20. The two rectangular frames 5 are symmetrically positioned on the top sides thereof, and are fixedly connected with atomizing nozzles 21 for spraying disinfectant on the docking plate 9. The two ends of the two drainage pipes 20 on each side, which are away from the rectangular slide bar 6, are penetrated to the inner wall of the atomizing nozzle 21 on the adjacent side and are fixedly connected. Each of the cylindrical tubes 18 is penetrated and fixedly connected at symmetrical positions on both sides of the piston plate 19, and is fixedly connected with a one-way liquid inlet valve 181 for quantitatively extracting the disinfectant from the disinfection box 17. The inner wall of each drainage pipe 20 near one end of the rectangular slide bar 6 is fixedly connected with a one-way drainage valve 201 for quantitatively discharging the disinfectant from the cavity 601.

[0047] When in use, through the disinfection box 17 set on the rectangular frame 5, and the disinfection box 17 is fixedly supported on the rectangular frame 5, the disinfectant is first stored in the interior of the disinfection box 17, and the cylindrical tube 18 is set on the transmission belt 15, then the cylindrical tube 18 is connected with the interior of the disinfection box 17, through the cavity 601 opened on the rectangular slide bar 6, and the cavity 601 set on the cylindrical tube 18, accompanied by the horizontal reciprocating movement of the rectangular slide bar 6, the piston plate 19 can be synchronously reciprocated horizontally on the inner wall of the cavity 601.

[0048] like Figures 6 to 10As shown, through the discharge pipe 20 provided on the rectangular slide bar 6 and the atomizing nozzle 21 provided on the rectangular frame 5, the discharge pipe 20 can connect the atomizing nozzle 21 with 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 is in a positive pressure state, and the internal air pressure at the other end is in a negative pressure state. Through the one-way liquid inlet valve 181 provided on the cylindrical tube 18 and the one-way liquid discharge valve 201 provided on the discharge pipe 20, the one-way liquid inlet valve 181 at one end is in a negative pressure state. The liquid valve 181 is in a closed state, and the one-way liquid discharge valve 201 is in an open state, so that the liquid discharge pipe 20 can discharge the internal disinfectant at one end of the cavity 601 into the interior of 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. At the same time, the one-way liquid inlet valve 181 at the other end is in an open state, and the one-way liquid discharge valve 201 is in a closed state, so that the cylindrical tube 18 can draw the disinfectant 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, the movement direction is opposite to that of the above-mentioned structure, and then the atomizing nozzle 21 can continuously spray disinfectant on the intravenous puncture instrument fragments on the surface of the material plate 9, thereby ensuring the continuity of the disinfectant spraying, improving the effect of disinfection on the intravenous puncture instrument fragments, and avoiding the intravenous puncture instrument fragments carrying bacteria, viruses and other pathogens, leading to human contact and causing the risk of secondary transmission.

[0050] Embodiment 4:

[0051] On the basis of the third embodiment, further:

As the bidirectional worm 10 rotates on a fixed axis, the worm wheel 23 can drive the cylindrical magnetic blocks 22 at both ends to rotate synchronously under the action of the bidirectional worm 10, and the receiving plate 9 shakes the intravenous puncture instrument fragments toward both ends at a uniform speed. Therefore, the cylindrical magnetic block 22 can evenly adsorb the needle fragments at both ends of the receiving plate 9 on the surface under the action of magnetic force, and at the same time, the plastic fragments in the intravenous puncture instrument fragments fall at a uniform speed from both ends of the receiving plate 9, thereby realizing the separation of the needle fragments and plastic fragments in the intravenous puncture instrument fragments, and further improving the efficiency of intravenous puncture instrument processing.

[0055] The scraper 24 is fixedly supported on the rectangular frame 5 by the scraper 24 arranged on the rectangular frame 5, and the scraper 24 is in contact with the surface of the cylindrical magnetic block 22. When the cylindrical magnetic block 22 rotates to adsorb and separate the needle fragments, the scraper 24 can hang down the needle fragments adsorbed on the surface of the cylindrical magnetic block 22, and through the guide hopper 25 and the collection box 26 arranged on the processing box 1, and the guide hopper 25 is located at the bottom of the scraper 24, so that the needle fragments dropped by the scraper 24 fall on the surface of the guide hopper 25, and the guide hopper 25 is placed obliquely, so that the guide hopper 25 can guide the needle fragments to the inner wall of the collection box 26 for centralized collection, and through the lower hopper 29 arranged on the processing box 1, and the lower hopper 29 is located at both ends of the receiving plate 9, the lower hopper 29 can discharge the separated fragments in a centralized manner, so that the subsequent medical staff can separately process the separated plastic fragments and needle fragments, further improving the efficiency of intravenous puncture instrument processing.

[0056] Embodiment five:

[0057] On the basis of the fourth embodiment, further:

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

[0059] When using, Figure 3 and Figure 4As shown, through the first protrusion 27 set on the rectangular frame 5, the first protrusion 27 is fixedly supported on the rectangular frame 5, and through the second protrusion 28 set on the receiving plate 9, the second protrusion 28 is made to correspond to the position of the first protrusion 27, and the movable block 8 is rotatably connected to the receiving plate 9, accompanied by the horizontal reciprocating shaking of the receiving plate 9, so that the movable block 8 can drive the receiving plate 9 to vibrate reciprocatingly under the action of the first protrusion 27 and the second protrusion 28, and the receiving plate 9 can lift the intravenous puncture instrument fragments on the surface upwards, and the lifted intravenous puncture instrument fragments are in contact with the cylindrical magnetic block 22, further improving the separation effect of the cylindrical magnetic block 22 on the needle fragments.
