Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical waste collection technology, and in particular to medical waste sorting and recycling bins. Background Technology
[0002] Medical waste contains harmful components such as pathogens, chemicals, and radioactive materials. If not properly sorted and disposed of, it can pollute the environment and potentially spread diseases, endangering public health. Under the framework of medical consortium construction, medical institutions at all levels collaborate closely to achieve resource sharing and unified management. The standardized sorting and recycling of medical waste has become a crucial link in ensuring medical safety and improving the overall operational standardization of the medical consortium. Scientific sorting facilitates targeted subsequent treatment; for example, infectious waste requires high-temperature sterilization, and chemical waste requires professional detoxification. Precise sorting can improve processing efficiency, reduce safety hazards, and align with the standardized and intensive management requirements of medical consortia for medical waste.
[0003] Existing medical waste sorting and recycling bins mostly adopt a multi-compartment design, with different waste types labeled on the bins, such as infectious, sharps, and chemical.
[0004] However, existing medical waste sorting and recycling bins use a simple flip-top design for the lid and body. During handling and transportation, if the bin is accidentally tipped over, the lid can easily fall off, causing waste to scatter. This not only increases the difficulty of cleaning but may also lead to the spread of germs and the risk of infection for personnel. This design cannot meet the needs for safe waste disposal in scenarios involving frequent transportation and handling between different medical institutions within a medical consortium. Utility Model Content
[0005] To address the above shortcomings, this utility model provides a medical waste sorting and recycling bin, which aims to improve the problem of the bin lid easily falling off during transportation in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] The medical waste sorting and recycling bin includes three recycling bins and a lid. The lid has a locking component installed inside, and the recycling bin on the right has a cutting component installed inside.
[0008] The locking assembly includes a slide groove, which is formed inside the bucket lid. A spring is fixedly connected inside the slide groove, and a locking block is fixedly connected to the other end of the spring. A slide rod is fixedly connected to the top of the locking block, and a locking tongue is fixedly connected to the top of the recycling bucket. The locking tongue and the locking block are engaged with each other.
[0009] As a further description of the above technical solution:
[0010] The cutting assembly includes a lower guillotine blade, which is fixedly connected to the inside of the recycling bin on the right side. A circular groove is provided inside the lower guillotine blade, and an upper guillotine blade is rotatably connected to the outside of the lower guillotine blade.
[0011] As a further description of the above technical solution:

The recycling bin on the right side has an inner frame one and an inner frame two slidably connected inside, and the recycling bin in the middle has an inner frame three slidably connected inside. The inner frames one, two, and three are all provided with grooves inside.
[0013] As a further description of the above technical solution:
[0014] A handle is fixedly connected to the top of the bucket lid;
[0015] As a further description of the above technical solution:
[0016] A water inlet pipe and a nozzle are fixedly connected to the outside of the recycling bin on the left side, and a valve is fixedly connected to the outside of the water inlet pipe.
[0017] As a further description of the above technical solution:

The pivot 2 is rotatably connected inside the fixing block 3.
[0038] Reference Figures 5-7 The cutting assembly includes a lower guillotine 15, which is fixedly connected to the inside of the right-side recycling bin 1. The lower guillotine 15 has a circular groove 17 inside, and its surface is evenly distributed with semi-circular grooves of different diameters to accommodate different sizes of medical instruments. An upper guillotine 16 is rotatably connected to the outside of the lower guillotine 15. The upper guillotine 16 has an arc-shaped cutting edge corresponding to the semi-circular grooves. Both the upper guillotine 16 and the lower guillotine 15 are made of stainless steel and are cleaned regularly. A partition 14 is fixedly connected to the inside of the right-side recycling bin 1. Fixed to the top of the partition 14, the right recycling bin 1 has an inner frame 19 and an inner frame 20 slidably connected inside, and the middle recycling bin 1 has an inner frame 3 slidably connected inside. The inner frames 19, 20 and 32 are all provided with grooves 21. The grooves 21 are for easy removal of the inner frames. The middle recycling bin 1 is for placing disposable gloves, cotton swabs, head covers, etc. It is also designed with a lock to fasten it. When recycling is required, simply use the hook to hook the groove 21 on the inner frame 3 22 to remove it.
[0039] Reference Figures 1-3 The outer side of the left recycling bin 1 is fixedly connected to a water inlet pipe 24 and a nozzle 10. The outer side of the water inlet pipe 24 is connected to an external water source. The outer side of the water inlet pipe 24 is fixedly connected to a valve 9. The valve 9 includes a valve body that provides a water passage, a valve core that controls the flow of water, a drive device that operates the valve core, a sealing ring to prevent water leakage, a threaded interface for pipe connection, and a limit mechanism to limit the valve core stroke. This is existing technology and will not be described in detail hereafter. The left recycling bin 1 is used to recycle waste medicine liquid. The waste liquid is poured into it and then discharged through the drain pipe 18. In addition, it needs to be cleaned frequently to prevent bacterial growth. Opening the valve 9 sprays high-pressure water into the left recycling bin 1. The waste liquid is discharged from the drain pipe 18 by opening the valve 23. This allows for quick cleaning. The outer side of each of the three recycling bins 1 is fixedly connected to a glass 7. The function of the glass 7 is to allow the internal waste to be seen. The outer side of the left recycling bin 1 is fixedly connected to a drain pipe 18, and the outer side of the drain pipe 18 is fixedly connected to a valve 23.
[0040] Working principle: First, when waste needs to be disposed of, slide the slide bar 6. The slide bar 6 moves the locking block 11 outward, the spring 12 contracts, and the locking tongue 13 disengages from the locking block 11, thus unlocking the device. At the same time, this locking structure prevents the device from collapsing during transportation and causing waste to spill out. There are three recycling bins 1. The left recycling bin 1 is used to collect waste medicine. The waste liquid is poured into the bin and then discharged through the drain pipe 18. In addition, it needs to be cleaned frequently to prevent bacterial growth. Open valve 1 9 to spray high-pressure water into the left recycling bin 1. The waste liquid is discharged through the drain pipe 18 by opening valve 2 23, which allows for quick cleaning.
[0041] The purpose of the middle recycling bin 1 is to hold disposable gloves, cotton swabs, head covers, etc. It is also designed with a locking buckle. When recycling is needed, simply use the hook to hook the groove 21 on the inner frame 3 22 to remove it. When using it, you can put a plastic bag over the inner frame 3 22 to avoid hand contact with waste and avoid infection. The right recycling bin 1 can recycle medical equipment with sharp objects, such as syringes and IV needles. Place the syringe on the lower guillotine 15, select the appropriate groove 17 according to the different sizes of the grooves 17, rotate the upper guillotine 16 to cut off the sharp part. The sharp part will fall naturally into the inner frame 1 19, and the remaining part will be placed in the inner frame 2 20. When recycling, use the hook to hook the groove 21 to replace it. This can be done quickly and will not cause injury from the sharp part during the process.
