The present invention will be further described below with reference to the embodiments.

[0029] Please refer to Figure 1 - Figure 7, in an embodiment of the present application, an infectious disease department medical waste collection and treatment device includes a barrel body 1, a cover body 4, and a disinfection mechanism. A collection area 2 is provided inside the barrel body 1. The opening at the top of the collection area 2 is closed by the cover body 4, and the opening on the side of the collection area 2 is closed by a closing door 21. One side of the closing door 21 is hinged to the barrel body 1; the outside of the collection area 2 is disinfected by the disinfection mechanism, and the disinfection mechanism is installed on the barrel body 1. A bag organizing mechanism is provided inside the collection area 2, and the bag organizing mechanism is used for storing and organizing garbage bags; the bag organizing mechanism includes a first bagging component 22, a second bagging component 25, a first slider 29, a sealing component 23, and a second slider 27. Uninterrupted medical garbage bags 24 are respectively stored on the first bagging component 22 and the second bagging component 25. The first bagging component 22 and the second bagging component 25 are arranged in sequence along the medical waste delivery direction, and the first bagging component 22 is fixedly connected to the barrel body 1;

[0030] Both the first bagging component 22 and the second bagging component 25 include a bag storage ring 34 and a cover ring 33. A bag storage area 35 is formed inside the bag storage ring 34, and the cover ring 33 is detachably covered on the bag storage area 35. Throwing areas 36 are formed on both the bag storage ring 34 and the cover ring 33. An outlet is provided at the connection between the cover ring 33 and the bag storage ring 34. The uninterrupted medical garbage bag 24 inside the bag storage area 35 extends into the throwing area 36 through the outlet;

[0031] The second bagging component 25 is slidably connected to the barrel body 1 through the second slider 27. The second bagging component 25 is also connected to a height adjusting member, and the height adjusting member is used to adjust the distance between the second bagging component 25 and the first bagging component 22; the uninterrupted medical garbage bag 24 on the second bagging component 25 is sleeved outside the uninterrupted medical garbage bag 24 containing medical waste on the first bagging component 22;

[0032] The sealing assembly 23 is located at the sealing position between the first bagging assembly 22 and the second bagging assembly 25. The sealing assembly 23 includes a heat-sealing cutting cooperation rod 31, a heat-sealing cutting member 30, and a first slider 29. The heat-sealing cutting cooperation rod 31 and the heat-sealing cutting member 30 are respectively located on both sides of the first bagging assembly 22. The heat-sealing cutting cooperation rod 31 and the heat-sealing cutting member 30 are respectively slidably connected to the barrel body 1 through the first slider 29. The two first sliders 29 are respectively connected to a sealing adjustment member. The sealing adjustment member is used to adjust the distance between the heat-sealing cutting cooperation rod 31 and the heat-sealing cutting member 30. The heat-sealing cutting cooperation rod 31 and the heat-sealing cutting member 30 seal the seamless medical waste bag 24 by clamping the seamless medical waste bag 24; during use, medical waste is put into the collection area 2. The medical waste is collected by the seamless medical waste bag 24 on the first bagging assembly 22. When the seamless medical waste bag 24 on the first bagging assembly 22 is full of waste, the sealing adjustment member in a group of sealing assemblies 23 is started to seal and segment the seamless medical waste bag 24, so as to seal the seamless medical waste bag 24 containing medical waste and the part of the seamless medical waste bag 24 on the first bagging assembly 22 or the second bagging assembly 25, facilitating the collection of medical waste next time; in order to further improve the sealing performance of the seal of the seamless medical waste bag 24, two groups of the sealing assemblies 23 are provided, and the two groups of the sealing assemblies 23 are arranged on the adjacent sides of the sealing position, so that the sealing position of the seamless medical waste bag 24 can be pressed into a bundle and segmented by starting the sealing adjustment member in the other group of sealing assemblies 23;

[0033] It should be noted that since the waste (including domestic waste) generated by isolated infectious patients or suspected infectious patients has high infectivity, it needs to be hermetically packaged with a double-layer medical waste bag. Therefore, after the seamless medical waste bag 24 on the first bagging assembly 22 is sealed and segmented, the height adjustment member adjusts the height of the second bagging assembly 25 to the position between the sealing position and the first bagging assembly 22; under the action of gravity, the seamless medical waste bag 24 on the second bagging assembly 25 sleevs the segmented seamless medical waste bag 24 containing medical waste, realizing the function of double-layer bagging. Then, the sealing assembly 23 is used to seal and segment the seamless medical waste bag 24 on the second bagging assembly 25. Then, the closing door 21 is opened, and after the segmented seamless medical waste bag 24 is taken out of the collection area 2, the second bagging assembly 25 is lowered to the initial position to complete the collection of medical waste next time.

[0034] It is necessary to explain that the heat-sealing cutting member 30 and the heat-sealing cutting cooperation rod 31 are heat-sealing cutters in the prior art, and the working principle thereof will not be elaborated in this embodiment.

[0035] In this embodiment, the height adjusting member includes a unidirectional lead screw 28, which is inserted into the threaded groove of the second slider 27 and threadedly connected to the second slider 27. The unidirectional lead screw 28 is also rotatably connected to the barrel body 1.

[0036] In this embodiment, the sealing adjusting member includes a bidirectional lead screw 32. The threaded portions at both ends of the bidirectional lead screw 32 are respectively inserted into the threaded grooves of different first sliders 29, and the bidirectional lead screw 32 is threadedly connected to the first sliders 29. The bidirectional lead screw 32 is also rotatably connected to the barrel body 1.

[0037] In this embodiment, the cover body 4 is hinged to one end of the barrel body 1 through a hinge shaft 5. The hinge shaft 5 is connected to the disinfection mechanism. The disinfection mechanism includes a hinge rod 10, a disc 9, a pump body 12, a first connecting pipe 14, a second connecting pipe 15, and a liquid storage tank 16. The disc 9 is driven to rotate by the hinge shaft 5. A transmission shaft 8 is installed on the disc 9. One end of the disc 9 is hinged to one end of the hinge rod 10. The other end of the hinge rod 10 is connected to a sealing piston 11. The sealing piston 11 is slidably installed in the liquid pumping area 20 of the pump body 12, and the sealing piston 11 seals the liquid pumping area 20. The water inlet of the liquid pumping area 20 is communicated with the liquid storage tank 16 through the first connecting pipe 14. The water outlet of the liquid pumping area 20 is communicated with the collection area 2 through the second connecting pipe 15. Check valve members 13 are installed in both the water inlet and the water outlet, and the guiding directions of the two check valve members 13 are opposite. When the cover body 4 opens and / or closes the collection area 2, the disinfectant liquid in the liquid storage tank 16 is sprayed into the collection area 2 under the action of the disc 9 and the sealing piston 11.

[0038] In this embodiment, a plurality of spraying ports 3 are formed on the collection area 2, and the plurality of spraying ports 3 are all communicated with the second connecting pipe 15.

[0039] In order to further enhance the disinfection effect, in this embodiment, the plurality of spraying ports 3 are arranged on the inner wall of the top of the collection area 2, so that during the process of opening and / or closing the cover body 4, the spraying ports 3 spray the disinfectant liquid into the collection area 2, perform timely disinfection treatment on the medical waste, effectively control the growth of viruses and bacteria, and thus reduce the infection risk to medical staff and other patients.

[0040] In this embodiment, the check valve member 13 includes a sealing plug 18 and a spring 17. The sealing plug 18 is slidably connected to the pump body 12. The two ends of the sealing plug 18 are respectively a connecting end and a sealing end. The connecting end is connected to the pump body 12 through the spring 17. When the sealing end abuts against the pump body 12, the liquid pumping area 20 is sealed; when the sealing end is spaced from the pump body 12, the liquid pumping area 20 is opened.

[0041] In actual application, when the cover body 4 is opened, the disc 9 rotates forward, and when the cover body 4 is closed, the disc 9 rotates backward. During the rotation of the disc 9, the sealing piston 11 will be driven to slide in the liquid pumping area 20. In this embodiment, taking the opening of the cover body 4 as an example, the forward rotation of the disc 9 drives the sealing piston 11 to move towards the water outlet of the liquid pumping area 20. During this process, due to the effect of negative pressure, the sealing plug 18 at the water outlet moves towards the connection end and compresses the spring 17, so that the sealing end is spaced from the pump body 12, and the disinfectant liquid in the liquid pumping area 20 flows to the second connecting pipe 15 through the gap between the pump body 12 and the sealing plug 18; the sealing plug 18 at the water inlet moves towards the direction close to the sealing end, so that the sealing end keeps in contact with the pump body 12 to seal the liquid pumping area 20; similarly, when the cover body 4 is closed and drives the disc 9 to rotate backward, the liquid in the liquid storage tank 16 is pumped into the liquid pumping area 20 through the first connecting pipe 14, so as to realize the reverse flow guiding function of the first connecting pipe 14 and the second connecting pipe 15. In order to further improve the flow guiding effect, a connecting hole 19 is formed in the sealing plug 18.

[0042] In order to save the installation space, in this embodiment, the disc 9 is connected to the hinge shaft 5 through a transmission assembly. The transmission assembly includes a first bevel gear 6, a second bevel gear 7 and a transmission shaft 8. The first bevel gear 6 is meshed and connected with the second bevel gear 7. The first bevel gear 6 is installed on the hinge shaft 5, the second bevel gear 7 is installed on the transmission shaft 8, the disc 9 is installed on the transmission shaft 8, and the transmission shaft 8 is rotatably connected to the barrel body 1, so that the disc 9 can be driven during the opening of the cover body 4 through the action of the first bevel gear 6 and the second bevel gear 7.

[0043] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.

[0044] In addition, it should be understood that although this specification is described according to implementation manners, not every implementation manner only contains an independent technical solution. This narrative manner of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation manners that can be understood by those skilled in the art.
