Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figure 1-5 This embodiment provides a technical solution: a medical waste collection device with disinfection function, including a medical waste collection box 1, which provides space for the collection of medical waste. A cover plate 2 is hinged to the inside of the feed inlet on the upper surface of the medical waste collection box 1. The cover plate 2 is hinged to the left end of the feed inlet of the medical waste collection box 1, which facilitates sealing the feed inlet of the medical waste collection box 1. Storage boxes 3 are provided inside the medical waste collection box 1 to provide space for the collection and storage of medical waste. The box door at the front of the medical waste collection box 1 is opened periodically to remove the storage box 3 and clean the medical waste inside. A microcontroller 11 is provided on the upper surface of the medical waste collection box 1. The input terminal of the microcontroller 11 is electrically connected to an external power source to control the start and stop of the entire device. It also includes a disinfection mechanism 4.Disinfection mechanism 4: It includes a disinfection shell 41, a feeding ramp 42, a baffle 43, and disinfection nozzles 44. The disinfection shell 41 is located on the top wall of the medical waste collection box 1. The opening on the upper surface of the disinfection shell 41 is connected to the inlet of the medical waste collection box 1. Storage boxes 3 are respectively located at the openings on the left and right ends of the lower surface of the disinfection shell 41, and both storage boxes 3 are connected to the disinfection shell 41. The left end of the disinfection shell 41 is provided with a reciprocating feeding ramp 42. The surface of the feeding ramp 42 is provided with filter holes. The baffle 43 is rotatably connected between the front and rear inner walls of the disinfection shell 41. The top wall of the disinfection shell 41 is provided with disinfection nozzles 44. During the disinfection process, the baffle 43 blocks the medical waste to concentrate on the upper surface of the feeding ramp 42 and through the feeding ramp 44. 2. The filter holes on the surface filter the liquid in the medical waste, achieving solid-liquid separation. Simultaneously, disinfectant is sprayed from the disinfection nozzle 44 to disinfect the solid medical waste and reduce the residue of liquid medical waste. The disinfectant, carrying the remaining liquid medical waste, falls through the filter holes into the storage box 3 on the left for collection and storage. The mixture of disinfectant and liquid medical waste disinfects the interior of the liquid medical waste. During disinfection, the feeding inclined plate 42 moves back and forth along its inclined direction, vibrating the medical waste on its surface to ensure more thorough solid-liquid separation and more comprehensive contact between the disinfectant and the medical waste, improving the disinfection effect. After disinfection, the baffle 43 removes its obstruction of the medical waste, allowing the solid medical waste to pass through. The waste continues to move down the surface of the discharge ramp 42 until it falls into the storage box 3 on the right for collection and storage. The disinfection mechanism 4 also includes a connecting pad 45, guide columns 46, and a vibration motor 47. The connecting pad 45 is set between the outer side of the discharge ramp 42 and the inner wall of the disinfection shell 41. The deformation of the connecting pad 45 seals the space between the discharge ramp 42 and the inner wall of the disinfection shell 41, providing space for the movement of the discharge ramp 42. The guide columns 46 are respectively set on the support plate surface of the lower surface of the discharge ramp 42. The left end of the guide column 46 passes through the guide inclined hole on the left side of the inner wall of the disinfection shell 41. The guide column 46 slides in the guide inclined hole, providing guidance and support for the movement of the discharge ramp 42. The left end of the guide column 46 is provided with a vibration motor 47 for the discharge. The movement of the inclined plate 42 provides power. The input end of the vibration motor 47 is electrically connected to the output end of the microcontroller 11. The sterilization mechanism 4 also includes a top material protrusion 48, which is respectively set on the upper surface of the feeding inclined plate 42, so that the feeding inclined plate 42 can more accurately move the medical waste on its surface. The upper end of the baffle 43 is provided with a rotating column 5, which is rotatably connected between the front and rear inner walls of the sterilization shell 41. Both the front and rear ends of the rotating column 5 extend out of the interior of the sterilization shell 41 and are provided with rotating plates 7. The lower end of the rotating plate 7 is rotatably connected to the surface of the sterilization shell 41. The fixed end of the electric push rod 8 is rotatably connected to the surface of the sterilization shell 41 through a rotating shaft one, and the telescopic end of the electric push rod 8 is rotatably connected to the lower end of the rotating plate 7 through a rotating shaft two.The input end of the electric push rod 8 is electrically connected to the output end of the microcontroller 11. When the electric push rod 8 is activated, its telescopic end applies force to the lower end of the rotating plate 7, causing the rotating plate 7 to push the rotating column 5 and the baffle 43 to rotate. This controls whether the baffle 43 blocks the movement of medical waste. A sealing gasket 6 is provided on the lower outer side of the baffle 43 to improve its sealing effect and block liquid medical waste. A liquid storage tank 10 is located at the lower interior of the medical waste collection box 1. A delivery pipe 9 is located at the outlet of the liquid storage tank 10, connecting to the lower interior of the liquid storage tank 10. Disinfection nozzles 44 are all connected to the delivery pipe 9. An infusion pump 12 is connected in series in the middle of the delivery pipe 9. The input end of the infusion pump 12 is electrically connected to the output end of the microcontroller 11. When the infusion pump 12 is activated, the disinfectant in the liquid storage tank 10 is sprayed out from the disinfection nozzles 44 through the delivery pipe 9.
[0016] The working principle of the medical waste collection device with disinfection function provided by this utility model is as follows: In use, the cover plate 2 is opened, and the medical waste is poured into the disinfection shell 41 through the inlet on the upper surface of the medical waste collection box 1. The medical waste falls downwards along the upper surface of the discharge ramp 42 inside the disinfection shell 41. At this time, the sealing gasket 6 at the lower end of the baffle 43 contacts the bottom wall of the disinfection shell 41, preventing the medical waste from continuing to fall, causing the medical waste to accumulate on the upper surface of the discharge ramp 42. The liquid in the medical waste is filtered through the filter holes on the surface of the discharge ramp 42, achieving solid-liquid separation. Simultaneously, the infusion pump 12 is started by the microcontroller 11, causing the disinfectant in the storage tank 10 to be sprayed out from the disinfection nozzle 44 through the delivery pipe 9, disinfecting the solid medical waste and reducing the residue of liquid medical waste. The disinfectant carries away the residual liquid... Liquid medical waste falls through the filter holes into the storage box 3 on the left for collection and storage. The liquid medical waste is disinfected by mixing it with disinfectant. During the disinfection process, the vibration motor 47 is started. Under the guidance and support of the guide column 46, the feeding inclined plate 42 moves back and forth along the inclined direction of the feeding inclined plate 42, vibrating the medical waste on the surface of the feeding inclined plate 42 to make the solid-liquid separation more thorough and the contact between the disinfectant and the medical waste more comprehensive, thereby improving the disinfection effect. After the disinfection is completed, the electric push rod 8 is started. The telescopic end of the electric push rod 8 applies a force to the lower end of the rotating plate 7, which pushes the rotating column 5 and the baffle 43 to rotate counterclockwise. This causes the baffle 43 to remove its obstruction of the medical waste, and the solid medical waste continues to move down along the surface of the feeding inclined plate 42 until it falls into the storage box 3 on the right for collection and storage.
[0017] It is worth noting that the microcontroller 11 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller. The vibration motor 47, electric push rod 8 and infusion pump 12 can be freely configured according to the actual application scenario. The vibration motor 47 can be a YZDP-10-2 model vibration motor, the electric push rod 8 can be a LAM1 model electric push rod, and the infusion pump 12 can be an LC-2060 model high-pressure infusion pump. The microcontroller 11 controls the operation of the vibration motor 47, electric push rod 8 and infusion pump 12 using methods commonly used in the prior art.
