Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment and collection technology, and more specifically, it relates to a medical waste treatment and collection device. Background Technology

[0002] Medical waste refers to waste generated during medical, diagnostic, treatment, or other healthcare activities. This waste may include infectious waste (such as syringes, needles, scalpels, blood and bodily fluids), pathological waste (such as tissue sections and cadavers), chemical waste (such as discarded medications and disinfectants), radioactive waste (such as waste from the use of radioactive isotopes), and other waste (such as disposable medical supplies, dressings, and gloves). Because medical waste may carry pathogens and hazardous substances, it needs to be collected using collection devices and transported to a centralized treatment facility. Existing medical waste collection devices typically have covers. When medical waste needs to be placed into the collection bin, the cover must be opened, allowing odors and bacteria to easily leak out, causing serious contamination of the medical facility. Furthermore, existing medical waste collection devices are relatively simple in function, lacking pretreatment capabilities and the ability to separate solids and liquids from the waste. When this medical waste is removed from the collection bin, the liquid can easily spill into the environment, causing further contamination. Utility Model Content

[0029] Please see Figure 1-5 A medical waste treatment and collection device includes a collection box 1, with a cover 2 hinged to the upper end of the collection box 1. Two support seats 3 are symmetrically arranged inside the collection box 1, and a rotating column 4 is movably arranged between the two support seats 3. The rotating column 4 is rotatably connected to the collection box 1, and a placement chamber 5 is provided on the rotating column 4. A first motor 6 is fixedly arranged on one side of the collection box 1, and the driving end of the first motor 6 extends into the collection box 1 and is fixedly connected to the rotating column 4. Two crushing rollers 7 are rotatably arranged inside the collection box 1, and a rotating rod 8 is provided on one side of each crushing roller 7. One end of the rotating rod 8 passes through the collection box 1 and is fixedly connected to a gear 9. The two gears 9 are meshed together. A second motor 10 is fixedly arranged on one side of the collection box 1, and a first transmission belt structure 11 is connected between the driving end of the second motor 10 and one of the rotating rods 8.

[0030] The collection box 1 is equipped with a filter plate 12 and a pusher plate 13 is movably installed inside the collection box 1.

[0031] In this embodiment, when medical waste needs to be placed into the collection box 1, the cover 2 is opened, and the opening of the placement chamber 5 on the rotating column 4 faces upward. At the same time, the rotating column 4 and the two support seats 3 cooperate to block the upper part of the collection box 1, making the collection box 1 disconnected from the outside. The medical waste is placed into the placement chamber 5, the cover 2 is closed, and the first motor 6 is started. The first motor 6 drives the rotating column 4 to rotate 180 degrees. The rotating column 4 drives the placement chamber 5 and the medical waste in the placement chamber 5 to rotate. When the opening of the placement chamber 5 is below the rotating column 4, the medical waste in the placement chamber 5 will fall into the collection box 1. The rotating column 4 continues to rotate 180 degrees, so that the opening of the placement chamber 5 rotates upward, thus preparing for the next placement of medical waste. The second motor 10 is started, and the second motor 10 drives one of the rotating rods 8 to rotate. The rotating rod 8 drives the gear 9 to rotate. Since the two gears 9 are meshed, the two gears 9 rotate in opposite directions. The gear 9 drives the other rotating rod 8 to rotate. The two rotating rods 8 drive the two crushing rollers 7 to rotate and crush the medical waste entering the collection box 1.

[0032] More specifically, when placing medical waste, it can be placed in the placement chamber 5, the cover 2 closed, and the rotating column 4 causes the medical waste to be placed into the collection box 1, where it is then pulverized by two pulverizing rollers 7. The pulverized medical waste will fall onto the filter plate 12, where solids are intercepted and liquids pass through the filter plate 12 into the bottom of the collection box 1, thus achieving solid-liquid separation.

[0033] Please see Figure 1-5 As an implementation method for automatically discharging medical waste: two guide plates 14 are symmetrically arranged inside the collection box 1, and two moving slots 15 are symmetrically arranged inside the collection box 1. A screw 16 is rotatably arranged in each moving slot 15. Each screw 16 is threadedly connected to a moving seat 17 that is movably connected to the moving slot 15. Both moving seats 17 are fixedly connected to the pusher plate 13. One end of each screw 16 passes through the collection box 1 and is connected to a second transmission belt structure 18. One of the screws 16 is fixedly connected to a third motor 19 that is fixedly arranged on one side of the collection box 1.

[0034] Specifically, the medical waste entering the collection box 1 moves along the two guide plates 14 to the space between the two crushing rollers 7 for crushing. The crushed medical waste falls onto the filter plate 12 for solid-liquid separation. When the medical waste needs to be removed from the collection box 1 for centralized processing, the third motor 19 is started. The third motor 19 drives one of the screws 16 to rotate. Under the action of the second transmission belt structure 18, the other screw 16 rotates at the same time. Since the screw 16 is threadedly connected to the moving seat 17, the moving seat 17 drives the pusher plate 13 to move. A drain port is provided on one side of the collection box 1. A drain cover is installed on the drain port by bolts. When the drain cover is opened, the two sides of the pusher plate 13 contact the inside of the collection box 1, and the bottom of the pusher plate 13 contacts the filter plate 12. Under the push of the pusher plate 13, the medical waste is discharged from the drain port, and the filter plate 12 is scraped and cleaned at the same time. A drain pipe is provided on one side of the collection box 1. Liquid can be discharged through the drain pipe for centralized treatment. The collection box 1 is equipped with a placement slot, and the pusher plate 13 will move into the placement slot for storage when not in use.

[0035] Please see Figure 1-5 As one method for disinfecting medical waste: the collection box 1 has a box body 20 on one side, the box body 20 is equipped with a storage battery, the collection box 1 has two water spray pipes 21 symmetrically arranged inside, each water spray pipe 21 is equipped with multiple nozzles 22, the box body 20 is equipped with a liquid storage tank 23, the liquid storage tank 23 is equipped with a pump body 24, the pump body 24 is connected to the two water spray pipes 21 and the liquid storage tank 23 respectively through pipes.

[0036] Specifically, the housing 20 is equipped with a battery that can provide power to the entire device. The storage tank 23 contains disinfectant. When the pump 24 is started, the pump 24 delivers the disinfectant in the storage tank 23 to the two spray pipes 21, and then sprays it out through the nozzles 22 to disinfect medical waste.

[0037] In summary, when using the overall equipment:

[0038] When medical waste needs to be placed in collection box 1, open cover 2. At this time, the opening of placement chamber 5 on rotating column 4 faces upward. Simultaneously, rotating column 4 and two support bases 3 cooperate to cover the upper part of collection box 1, preventing collection box 1 from communicating with the outside. Place medical waste into placement chamber 5, close cover 2, and start first motor 6. First motor 6 drives rotating column 4 to rotate 180 degrees. Rotating column 4 drives placement chamber 5 and the medical waste in placement chamber 5 to rotate. When the opening of placement chamber 5 is below rotating column 4, the medical waste in placement chamber 5 will fall into collection box 1. Rotating column 4 continues to rotate 180 degrees, so that the opening of placement chamber 5 rotates upward, thus preparing for the next placement of medical waste.

[0039] When pretreatment of medical waste entering the collection bin 1 is required, the medical waste moves along the two guide plates 14 to the space between the two crushing rollers 7 for crushing. The second motor 10 is then activated, driving one of the rotating rods 8 to rotate. The rotating rod 8 drives a gear 9 to rotate. Because the two gears 9 are meshed, they rotate in opposite directions, driving the other rotating rod 8 to rotate. The two rotating rods 8 then drive the two crushing rollers 7 to crush the medical waste entering the collection bin 1. The crushed medical waste falls onto the filter plate 12. Solids are intercepted by the filter plate 12, while liquids pass through the filter plate 12 and enter the bottom of the collection bin 1, thus achieving solid-liquid separation.

[0040] When it is necessary to spray disinfectant on the medical waste in the collection box 1, the storage battery in the box 20 can provide power to the entire device. The storage tank 23 contains disinfectant. The pump 24 is started, and the pump 24 delivers the disinfectant in the storage tank 23 to the two spray pipes 21, and then sprays it out through the nozzle 22 to disinfect the medical waste.

[0041] When medical waste needs to be discharged from collection box 1, collection box 1 has multiple rollers at the bottom and a push handle on one side. Pushing the push handle rotates the rollers, allowing collection box 1 to move and centrally process medical waste. Starting the third motor 19 drives one of the screws 16 to rotate. Under the action of the second transmission belt structure 18, the other screw 16 rotates simultaneously. Since screw 16 is threadedly connected to the moving seat 17, the moving seat 17 moves the pusher plate 13. Collection box 1 has a drain port on one side, with a drain cover bolted to it. Opening the drain cover allows the pusher plate 13 to contact the inside of collection box 1 on both sides and the bottom of the pusher plate 13 to contact the filter plate 12. Pushed by the pusher plate 13, medical waste is discharged from the drain port, simultaneously scraping and cleaning the filter plate 12. Collection box 1 also has a drain pipe on one side, allowing liquids to be centrally discharged for further treatment. The collection box 1 has a placement slot, into which the pusher plate 13 moves for storage when not in use. The entire device is controlled by a controller. Since the controller is matched with common equipment and represents existing mature technology, its electrical connections and specific circuit structure will not be described in detail here. A protective shell is provided on one side of the collection box 1 to protect the driving components.

[0042] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
