Medical guidewires are widely used in interventional therapy and minimally invasive surgery. Their core components are made of unique nickel-titanium alloy or 304 stainless steel, with lengths ranging from 45-300cm, and have superelasticity and shape memory properties. However, in the process of disposing of medical waste, the harmless treatment center found that guidewire-type medical waste often entangled and stuck in the grate during incineration, making it difficult to rotate, or formed into wire mesh and clumps in the furnace, blocking the slag outlet. Frequent shutdowns for maintenance for this reason greatly reduced the efficiency and stability of the equipment, and ultimately had an adverse impact on the normal medical waste treatment capacity.

[0013] Beneficial effects

[0014] Compared with the existing technology, the advantages of the automatic crusher for guidewire medical waste of the present invention are:

[0015] 1. After use, medical staff insert the guide wire into the oblique channel through the barrel lid feed port. The shredder mechanism then cuts the long guide wire into multiple segments, which then fall into the sharps box. When the sharps box reaches 3 / 4 of its capacity, the waste is extracted through the first opening of the barrel, effectively sealed, and transported to a harmless treatment center for incineration. During the incineration process, the guide wire medical waste is fully shredded, effectively preventing entanglement and grate jamming, ensuring unobstructed slag discharge, and thus ensuring the long-term stable operation of the incinerator, reducing maintenance frequency, and improving medical waste treatment efficiency.

[0016] 2. When the guidewire is crushed, fragments tend to fly. To prevent these fragments from escaping from the barrel lid's feed port and potentially causing injury to medical personnel, we've cleverly installed a wool strip in the middle of the diagonal channel. The wool strip effectively blocks flying fragments, ensuring the safety of medical personnel during operation.

[0017] 3. When in use, the crushing mechanism must be inserted into the dedicated slot on the top of the lid. To remove the crushing mechanism, first remove the lid through the second opening on the top of the barrel. Then, loosen the screws and easily pull the crushing mechanism out of the lid's slot. Both the crushing mechanism and the lid can now be cleaned, disinfected, and maintained independently, making the process quick and easy.

[0018] 4. The operation panel is cleverly designed on the top of the barrel cover, and is equipped with a convenient switch to easily control the opening and closing of the crushing mechanism, greatly improving the convenience of operation.

[0019] 5. When the medical staff pushes the sharps box from the first opening of the barrel body to the inside of the barrel body, thanks to the ingenious design of the auxiliary structure of the opening and closing cover, the sharps box cover can be automatically opened to ensure that the discharge port is unobstructed; conversely, when the sharps box is pulled out of the barrel body, the auxiliary structure prompts the box cover to close quickly. This not only effectively prevents the medical waste fragments from being scattered due to hand shaking during operation by medical staff, but also greatly reduces the risk of guidewire-like medical waste fragments accidentally falling out of the discharge port during transportation of the sharps box, thereby significantly improving the safety of use and reducing potential safety hazards.

[0020] 6. In the auxiliary structure of the switch cover, we cleverly utilize the coordinated cooperation of the pin and the guide rail to achieve a simple and efficient structure. This design eliminates the need for an additional power mechanism, significantly reducing production costs.

[0021] 7. With the transparent window design of the sharps box, medical staff can easily check the storage status of medical waste inside at any time, ensuring that the sharps box is replaced in time when the 3 / 4 capacity limit stipulated in the medical waste management regulations is reached, thereby effectively preventing machine damage or other adverse conditions caused by overfilling.

[0033] Example

[0034] The specific implementation of the utility model is as follows Figures 1 to 8 As shown, an automatic shredder for guidewire-type medical waste includes a barrel body 1, with a second opening 12 provided at the top of the barrel body 1 and a first opening 11 provided on the side wall of the barrel body 1. A barrel cover 4 is provided at the second opening 12 of the barrel body 1. The barrel cover 4 is provided with a feed port 41 and an oblique channel 42 that are connected in sequence. A shredder mechanism 5 is provided at the end of the oblique channel 42. A sharps box 2 is provided at the first opening 11 of the barrel body 1, which is slidably engaged with the sharps box 2 and can be withdrawn. A handle 22 and a transparent window 23 are provided on the front side wall of the sharps box 2.

[0035] A wool strip 43 is connected to the middle of the oblique channel 42. The wool strip 43 is adapted to the width of the oblique channel 42 so that the wool strip 43 can completely block the middle of the oblique channel 42. The thickness of the wool strip 43 is set so that when guidewire-type medical waste fragments splash, the fragments cannot pass through the wool strip 43.

[0036] A crushing mechanism insertion slot 430 is provided at the top of the lid 4. The crushing mechanism 5 comprises an operating panel 53 and a base 51, connected sequentially from top to bottom. The base 51 is removably inserted into the crushing mechanism insertion slot 430 and is connected to the lid 4 via screws 6. A base channel is provided in the middle of the base 51, which communicates with the oblique channel 42. In this embodiment, the input end of the base channel is connected to the oblique channel 42, and the output end of the base channel is located at the bottom of the base 51 and communicates with the inner cavity of the barrel body 1.

[0037] The crushing mechanism 5 also includes a driving device 55 and a pair of two crushing rollers 52 that are interconnected. The two crushing rollers 52 are parallel to each other and are rotatably connected to the middle of the base channel of the base 51. In this embodiment, the driving device 55 includes a motor that drives the two crushing rollers 52 to rotate synchronously. The main body of the motor is installed on the base 51 and is not located in the base channel to avoid contact with medical waste fragments. The two crushing rollers 52 rotate in opposite directions, as shown by the arrows of the rotation direction. Figure 4 Taking the guide wire 7 as an example, when the guide wire 7 passes between the two crushing rollers 52, the guide wire 7 is shredded by the two crushing rollers 52.

[0038] A switch 54 is provided on the operation panel 53 . The switch 54 is electrically connected to the driving device 55 . The switch 54 may be a button or a touch switch.

[0039] A limiting protrusion 13 is provided on the inner wall of the second opening 12, and the barrel cover 4 is detachably inserted into the second opening 12 of the barrel body 1, and the bottom edge of the barrel cover 4 is supported on the limiting protrusion 13. In this embodiment, the limiting protrusion 13 is provided on the front and rear inner walls of the second opening 12, such as Figure 2 A drop guide slope 14 is provided on the inner wall of the barrel body 1 adjacent to the output end of the base channel of the base 51. The lower end of the drop guide slope 14 is inclined toward the drop opening 20 of the sharps box 2, ensuring that medical waste fragments can accurately pass through the drop opening 20 of the sharps box 2 when flying out of the base channel output end.

[0040] The top rear half of the sharps box 2 is provided with a blanking port 20 with an opening facing upward, and a flap 21 is provided above the blanking port 20. The front end of the flap 21 is rotatably connected to the middle of the top surface of the sharps box 2 via a rotating shaft 24. An auxiliary structure for a switch cover is provided between the flap 21 and the barrel body 1. The rear end of the flap 21 and the sharps box 2 are interlocked with each other through snap-fitting protrusions 27. There are two snap-fitting protrusions 27, which are respectively arranged on the rear end of the flap 21 and the rear side wall of the sharps box. After the flap 21 is snapped in, it takes a little force to open the flap 21, which is safer. The width of the flap 21 is basically the same as the width of the inner cavity of the barrel body 1. When the flap 21 is opened upward, it blocks the falling medical waste fragments and prevents the fragments from passing through the barrel body 1 from the first opening 11.

[0041] The cover opening and closing auxiliary structure includes a pin 26 and a guide rail 3 that slidably engage each other. The pin 26 is connected to the flip cover 21 via a bracket 25. When the flip cover 21 is closed, it is horizontally arranged, with the pin 26 located above the flip cover 21 and away from the rotating shaft 24. The guide rail 3 is provided on the inner wall of the barrel body 1. In this embodiment, the pin 26 and guide rail 3 are provided in two sets and are arranged symmetrically.

[0042] The guide rails 3 comprise a first guide rail 31 and a second guide rail 32, interconnected from bottom to top. The lower end of the first guide rail 31 is inclined toward the first opening 11 and has an opening at its lower end for the pin 26 to slide in and out. The second guide rail 32 is arranged vertically. Because the first guide rail 31 is inclined, and the pin 26 is positioned above the flip cover 21 and away from the pivot 24 when the flip cover 21 is closed, the flip cover 21 does not become stuck or unable to flip when the pin 26 enters and slides along the first guide rail 31.

[0043] When the sharps box 2 is pulled out, the pin 26 can slide down along the second guide rail 32 under the action of the gravity of the flip cover 21 and finally slide out from the lower end of the first guide rail 31. In this process, the flip cover 21 will not be stuck and cannot be turned over. After the sharps box 2 is completely pulled out, the medical staff will check whether the lower flip cover 21 is fastened to the sharps box 2 by the snap-fit ​​protrusion 27. If not, press the lower flip cover 21 again to ensure that the lower flip cover 21 is fully fastened before transporting the sharps box 2.

[0044] Taking the guide wire 7 as an example, when the guide wire 7 is used up, the medical staff activates the crushing mechanism 5 through the switch 54, and extends the guide wire 7 from the feed port 41 of the barrel cover 4 into the oblique channel 42. The two crushing rollers 52 of the crushing mechanism 5 cut the long guide wire 7 into fragments, and the chopped guide wire fragments fall into the sharps box 2. The sharps box 2 is regularly pulled out from the first opening 11 of the barrel body 1, and the sharps box 2 and the guide wire medical waste stored therein are uniformly recovered and incinerated by the harmless treatment center. During incineration, since the guide wire medical waste in the sharps box has been fully chopped, entanglement and grate jamming are effectively prevented, ensuring the unobstructed slag outlet, thereby ensuring the long-term stable operation of the incinerator, reducing the maintenance frequency, and improving the efficiency of medical waste treatment.

[0045] The present invention is described above in conjunction with the best embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations based on the essence of the present invention.
