[0016] The following embodiments of the technical solution of the invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the invention and are therefore only examples and cannot be used to limit the scope of protection of the invention.
[0017] like Figure 1-2 As shown, this embodiment provides a medical device recycling and pre-processing device, comprising: a mobile vehicle 1, a cleaning component 2, and a disinfection device 3. The mobile vehicle 1 has a delivery port 4 on its upper portion, which is tilted to prevent the scissors' tips from directly contacting the first conveyor belt 21 when they fall. The cleaning component 2 is disposed within the mobile vehicle 1 and below the delivery port 4, so that the scissors fall directly onto the cleaning component 2. The disinfection device 3 is located on one side of the cleaning component 2. The cleaning assembly 2 includes a first conveyor belt 21 and a flushing device 22. The flushing device 22 is located in the mobile vehicle 1 and the upper part of the flushing device 22 is fixedly connected to the first conveyor belt 21. The first conveyor belt 21 drives the scissors to move, and at this time, the scissors are preliminarily flushed by the flushing device 22 to remove stains.
[0018] The delivery port 4 is arranged at an angle, and the first conveyor belt 21 is arranged at an angle, so that the scissor tip first contacts the upper part of the first conveyor belt 21. A support frame 5 is connected to the first conveyor belt 21 for placing the scissor handles. An anti-slip strip 6 is provided in the middle of the first conveyor belt 21 to prevent the scissor tip from slipping.
[0019] The disinfection device 3 includes an opening device 31, a disinfection component 33 and a second conveyor belt 32. The disinfection component 33 is located on one side of the first conveyor belt 21, so that the scissors fall onto the second conveyor belt 32 after being cleaned by the first conveyor belt 21. The disinfection component 33 is fixedly connected to the second conveyor belt 32, so that the disinfection component 33 fixes the second conveyor belt 32. The disinfection component 33 fixes the opening device 31 above the second conveyor belt 32, and the scissors are opened by the opening device 31 to facilitate the disinfection of the scissors. A receiving plate 13 is installed on one side of the second conveyor belt 32 to store the disinfected scissors. A discharge port 15 is provided on one side of the mobile vehicle 1, and the receiving plate 13 is located on the discharge port 15 to facilitate the removal of the scissors. An ultraviolet lamp 14 is connected to the discharge port 15 to perform secondary disinfection on the scissors.
[0020] The working principle of the above scheme is: put the scissors with the tip facing the delivery port 4, and the scissors will fall onto the first conveyor belt 21 along the delivery port 4. At this time, the tip of the scissors will first contact the anti-slip strip 6 to prevent the scissors from sliding directly. The first conveyor belt 21 moves the scissor handle backward and falls on the support frame 5. At this time, the scissors are set obliquely on the first conveyor belt 21. The cleaning liquid is flushed through the flushing device 22 to clean the stains on the scissors. At this time, the scissors fall onto the second conveyor belt 32 after cleaning, and the scissors are opened by the opening device 31 to facilitate cleaning and disinfection of the inside of the scissors. The opened scissors are disinfected by the disinfection component 33, and then the disinfected scissors are conveyed to the discharge port 15 by the second conveyor belt 32. The scissors are stored by the receiving plate 13, and then the scissors are irradiated and disinfected by the ultraviolet lamp 14.
[0021] The beneficial effects of the above solution are as follows: the cleaning component 2 allows the scissors to be placed at an angle and rinsed at the same time; the cleaning component 2 allows the scissors to be cleaned separately during cleaning, thereby preventing cross-infection of germs on the scissors; the feeding port 4 is set at an angle, so that when the scissors fall, the tips of the scissors fall on the first conveyor belt 21 first, and then the handles of the scissors fall backward and fall on the support frame 5, thereby fixing the shape of the scissors after falling; The scissors are sprayed with disinfectant by the disinfection component 33 so that the scissors can be evenly disinfected while preventing cross infection of the scissors.
[0022] In one embodiment of the present invention, Figures 1-3 As shown, the cleaning assembly 2 includes a first liquid storage barrel 221, a first collection barrel 222, and a water spray head 223. Both the first liquid storage barrel 221 and the first collection barrel 222 are located within the mobile vehicle 1. The first liquid storage barrel 221 is used to store cleaning fluid. The first conveyor belt 21 is mounted above the first liquid storage barrel 221. Multiple water spray heads 223 are fixed on both sides of the first conveyor belt 21. The water spray heads 223 spray water toward the first conveyor belt 21 to prevent water from splashing. The cleaned wastewater falls along the first conveyor belt 21 into the first collection barrel 222. A water inlet pipe 224 is connected between the first liquid storage barrel 221 and the water spray head 223, allowing water in the first liquid storage barrel 221 to enter the water spray head 223 through the water inlet pipe 224. A water pump or other device may be provided within the first liquid storage barrel 221 to facilitate drainage from the water inlet pipe 224.
[0023] The working principle of the above solution is as follows: when the scissors are located on the upper part of the first conveyor belt 21, the cleaning liquid is pumped out by the water pump, and then the water spray head 223 sprays water to clean the scissors.
[0024] The above solution has the beneficial effects of: the cleaning component 2 allows the scissors to be placed at an angle and rinsed at the same time; the cleaning component 2 allows the scissors to be cleaned separately, thus avoiding cross infection of germs on the scissors.
[0025] In one embodiment of the present invention, Figures 1 to 6 As shown, the disinfection assembly 33 includes: a second liquid storage barrel 331, a second collection barrel 332, a fixed trough 333, and a liquid spraying port 334. The second liquid storage barrel 331 and the second collection barrel 332 are both located at the bottom of the mobile vehicle 1, and the second conveyor belt 32 is mounted above the second liquid storage barrel 331. A water outlet pipe 335 is fixedly connected between the fixed trough 333 and the second liquid storage barrel 331, thereby securing the fixed trough 333. A water pump or other device may be provided within the second liquid storage barrel to facilitate drainage through the water outlet pipe 335. The fixed trough 333 is fixedly mounted above the second conveyor belt 32. The fixed trough 333 is configured in two halves, with a through slot formed between the fixed troughs 333 to facilitate passage of the telescopic rod 311. Multiple liquid spraying ports 334 are located inside the fixed trough 333 and connected through the water outlet pipe 335 to spray disinfectant onto the scissors.
[0026] The opening device 31 comprises a telescopic rod 311, a first slide bar 312, a first spring 313, a slider 316, and a connecting rod 314. The telescopic rod 311 is fixedly connected to the second conveyor belt 32, which drives the telescopic rod 311. A sloping plate 10 is connected to one side of the fixed slot 333, allowing the scissors driven by the first conveyor belt 21 to slide onto the fixed slot 333 via the sloping plate 10. The first slide bar 312 is connected to the inner side of the fixed slot 333. The slider 316 consists of two pieces and is slidably connected to the first slide bar 312, allowing the slider 316 to slide on the first slide bar 312.
[0027] There are two first springs 313 and they are located on both sides of the slider 316, so that the slider 316 can rebound and reset. The connecting rod 314 is fixedly connected to the inner side of the fixed groove 333, and the lower side of the connecting rod 314 is connected to the support rod 315 to prevent the slider 316 from getting stuck on the side of the support rod 315 after flipping. One side of the fixed groove 333 is in an arc shape to prevent the scissors from falling vertically. The bottom of the mobile vehicle 1 is connected to a shaking device 12, and the upper part of the shaking device 12 is connected to a filter 11, so that the shaking device 12 drives the filter 11 to shake and shake off the remaining moisture in the scissors. The side of the slider 316 is slidably connected to a second slide bar 8, and the outer side of the second slide bar 8 is covered with a second spring 9. One end of the second slide bar 8 is connected to a resistance block 7, so that the tip of the scissors first contacts the resistance block 7 to pre-open the scissors. The resistance block 7 is made of a hard material so that the scissors will not get stuck on the resistance block 7. One side of the slider 316 is made of rubber, so that the tip of the scissors can drive the slider 316 to move The above scheme works as follows: When the scissors slide down to the fixed groove 333 through the inclined plate 10, the second conveyor belt 32 starts to drive the telescopic rod 311 to move. The telescopic rod 311 passes through the inclined plate 10 and collides with the inclined plate 10. The telescopic rod 311 is compressed and then resets. The telescopic rod 311 now collides with the scissors handle, driving the scissors to move. When the scissors contact the contact block 7, the scissors compress the contact block 7, which forces the scissors to open. The scissors contact the inclined surface of the contact block 7, causing the scissors to open. The scissors' tips collide with the slider 316. The telescopic rod 311 continues to drive the scissors to move, causing the slider 316 to move toward the inside of the fixed groove 333. The scissors are now fully extended. Disinfectant is then discharged through the liquid spray port 334 to disinfect the scissors, thereby sterilizing the cutting surface. The waste liquid after disinfection flows along the second conveyor belt 32 into the second collection bucket 332. Slider 316 moves to a distance where it no longer interferes with support rod 315. At this point, slider 316 rotates and no longer interferes with the scissors. The scissors are then driven by telescopic rod 311 through slider 316 to the arc end of fixed slot 333. The scissors fall onto filter screen 11, where the shaking device 12 shakes off any remaining water stains. The scissors are then shaken off filter screen 11 and onto receiving plate 13 for storage. Simultaneously, ultraviolet light 14 is activated to irradiate the scissors for secondary disinfection.
[0028] The beneficial effects of the above scheme are as follows: when the scissors fall onto the fixed groove 333 through the inclined plate 10, the scissors tips first move downward, and at this time the second conveyor belt 32 drives the telescopic rod 311 to move and conflict with the scissors handle. At this time, the scissors tip contacts the conflicting block 7, the scissors stop moving, the telescopic rod 311 continues to move, thereby stretching the scissors handle to open the scissors, and at this time the opened scissors are disinfected, making the disinfection of the scissors more thorough; when the scissors tip contacts the slider 316, the slider 316 is forced to slide toward the inside of the fixed groove 333 on both sides, and the support rod 315 conflicts with the slider 316 so that the slider 316 does not rotate when moving. When the slider 316 slides to the end of the support rod 315, the slider 316 is pushed by the scissors tip, and the slider 316 flips over and the scissors can continue to move; the scissors are caught by the filter 11 and the shaking device 12 to shake off the residual disinfectant on the scissors, and the scissors slide onto the receiving plate 13 to be stored.
