Description

Technical Field

[0001] This utility model relates to the field of medical waste treatment equipment technology, and in particular to a plasma medical waste disinfection and sterilization device. Background Technology

[0002] Medical waste refers to solid or semi-solid waste generated by medical institutions at all levels and of all types during medical treatment, prevention, healthcare, rehabilitation, and other related diagnostic and treatment activities. This waste poses direct or indirect infectious, pathological, damaging, pharmaceutical, or chemical hazards. Because it carries large numbers of pathogenic microorganisms (including bacteria, viruses, fungi, etc.) and toxic and harmful substances, it is a form of spatial pollution, capable of spreading and contaminating the environment through airborne droplets and aerosols; it is acutely infectious, as direct contact or short-term exposure can easily lead to infectious diseases; and it is latently infectious, as some pathogens can survive for extended periods and pose a chronic transmission risk through environmental media. During the disposal process, medical institutions must use dedicated medical waste bins for classified collection and temporary storage. It is important to note that standard dedicated medical waste bins only provide basic protective functions such as sealing and leak prevention; they do not possess sterilization properties. If the collection process is not handled properly, the temporary storage environment does not meet temperature and humidity requirements, or if containers are damaged or seals fail during transportation, contaminant leakage can easily occur, leading to cross-contamination between different types of waste and creating a public health risk of secondary disease transmission. Utility Model Content

[0003] In view of this, in order to solve the problems of easy leakage, cross-infection and secondary transmission of medical waste during collection, temporary storage and transportation, the embodiments of this utility model provide a plasma medical waste disinfection and sterilization device.

[0004] An embodiment of this utility model provides a plasma medical waste disinfection and sterilization device, comprising: The container has an open top, allowing garbage bags to be inserted into it. The lid has an openable top cover. The container includes multiple sterilization columns, each with a lid fixedly connected to its upper end. The lid closes to the upper port of the container, allowing all sterilization columns to be spaced apart around the inner wall of the container and inserted into the garbage bag. Each sterilization column includes a hollow outer shell and, from top to bottom, an upper plasma generator, an air pump, and a lower plasma generator arranged sequentially within the outer shell. The outer shell has an upper air hole above the upper plasma generator and a lower air hole below the lower plasma generator. The pumping directions of any two adjacent sterilization columns are opposite, allowing airflow to pass sequentially around the inner wall of the container through each sterilization column.

[0005] Furthermore, one side of the outer casing is provided with a detachable side cover plate, and the upper air hole and the lower air hole are respectively located at the upper and lower ends of the side cover plate.

[0006] Furthermore, the upper air holes of each of the sterilization columns are located at the same height, and the lower air holes of each of the sterilization columns are located at the same height.

[0007] Furthermore, the box body is rectangular in shape.

[0008] Furthermore, the number of disinfection and sterilization columns is four, and the box lid is closed to the upper port of the box body so that the four disinfection and sterilization columns are inserted into the four corners of the box body.

[0009] Furthermore, the outer shell is cylindrical.

[0010] Furthermore, the pumping direction of the air pump is vertical.

[0011] Furthermore, the air pump inside the outer casing is positioned between the upper plasma generator and the lower plasma generator.

[0012] Furthermore, the top of the box cover is provided with a power supply interface for supplying power to the plasma medical waste disinfection and sterilization device.

[0013] Furthermore, both the upper plasma generator and the lower plasma generator use barrier discharge-DBD as their dielectric.

[0014] The beneficial effects of the technical solution provided by the embodiments of this utility model are as follows: In this utility model, a plasma medical waste disinfection and sterilization device involves inserting a garbage bag into the inner part of the container, then closing the lid to allow each disinfection and sterilization column to be inserted into the garbage bag. Medical waste can then be placed into the garbage bag by opening the upper cover. The upper plasma generator, air pump, and lower plasma generator of each disinfection and sterilization column are activated. Under the action of the air pump, airflow sequentially passes through each disinfection and sterilization column, circulating within the garbage bag. When the plasma generated by the upper and lower plasma generators comes into contact with microorganisms in the medical waste, it destroys the structure and function of the microorganisms, thereby achieving the purpose of disinfection and sterilization. This device can promptly disinfect and sterilize microorganisms in medical waste, preventing leakage, cross-infection, and secondary transmission of medical waste during collection, temporary storage, and transportation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please refer to Figure 1 and 2 An embodiment of this utility model provides a plasma medical waste disinfection and sterilization device, including a box body 1, a box cover 2, and multiple disinfection and sterilization columns 4.

[0024] The upper end of the container 1 is open, allowing garbage bags to be inserted into it. The interior of the container 1 is used to hold garbage bags, typically medical waste plastic bags. Garbage placed inside the container 1 is stored within these garbage bags. The shape of the container 1 can be flexibly configured according to the actual application scenario; for example, in this embodiment, the container 1 is rectangular.

[0025] The lid 2 closes to the upper port of the box body 1, and the top of the lid 2 is provided with an openable upper cover plate 3. The shape of the lid 2 is adapted to the shape of the upper port of the box body 1. In this embodiment, the shape of the lid 2 is also set as a cuboid, which can tightly close to the upper port of the box body 1.

[0026] The upper cover 3 is aligned with the interior space of the container 1 and is located directly above the opening of the garbage bag. The upper cover 3 is connected to the container lid 2 by a hinge, allowing the upper cover 3 to rotate relative to the container lid 2, thereby opening or closing the upper cover 3. When the upper cover 3 is open, medical waste can be placed into the garbage bag.

[0027] Please refer to Figure 3 Each of the sterilization columns 4 is fixedly connected to the top of the box cover 2. The box cover 2 is closed to the upper port of the box body 1 so that all the sterilization columns 4 are distributed around the inner wall of the box body 1 at intervals. Each sterilization column 4 includes a hollow outer shell 5 and an upper plasma generator 6, an air pump 7 and a lower plasma generator 8 arranged sequentially from top to bottom inside the outer shell 5. The outer shell 5 has an upper air hole 10 above the upper plasma generator 6 and a lower air hole 11 below the lower plasma generator 8. The pumping directions of the air pumps 7 of any two adjacent sterilization columns 4 are opposite, so that the airflow flows around the inner wall of the box body 1 and passes through each sterilization column 4 in sequence.

[0028] The number of disinfection and sterilization columns 4 can be flexibly set according to the shape and volume of the box body 1. Each disinfection and sterilization column 4 is generally evenly spaced around the inner wall of the box body 1. In this embodiment, the shape of the box body 1 is a cuboid, and the number of disinfection and sterilization columns 4 is four. The box cover 2 is closed to the upper port of the box body 1 so that the four disinfection and sterilization columns 4 are inserted into the four corners of the box body 1, that is, into the four corners of the garbage bag fitted inside the box body 1, and are evenly distributed on the edge of the garbage bag.

[0029] The shape of the outer shell 5 can be flexibly set according to the shape and volume of the box 1. The shape of the outer shell 5 is generally set as a long strip, such as the cylindrical shape of the outer shell 5 in this embodiment.

[0030] It should be noted that, along the direction surrounding the inner wall of the housing 1, the pumping directions of any two adjacent sterilization columns 4 are opposite. For example, in this embodiment, the pumping direction of the air pump 7 is vertical. For any two adjacent sterilization columns 4, the pumping direction of one sterilization column 4's air pump 7 is vertically downward, and the pumping direction of the adjacent sterilization column 4's air pump 7 is vertically upward. Thus, the airflow enters from the upper air hole 10 at the top of one sterilization column 4 and flows to the lower air hole 11 at the bottom. From there, it flows into the lower air hole 11 at the bottom of the adjacent sterilization column 4, and then back to the upper air hole 10. This process continues in a similar manner. Figure 4 The arrows in the text flow sequentially through each of the disinfection and sterilization columns 4.

[0031] In order to direct the airflow, in some preferred embodiments, the upper air holes 10 of each of the sterilization columns 4 are located at the same height, and the lower air holes 11 of each of the sterilization columns 4 are located at the same height, so that the airflow flows accurately between adjacent sterilization columns 4.

[0032] Please refer to Figure 4 and 5 In some embodiments, a detachable side cover plate 9 is provided on one side of the outer casing 5, and the upper air hole 10 and the lower air hole 11 are respectively provided at the upper end and the lower end of the side cover plate 9, which facilitates the installation and maintenance of the upper plasma generator 6, the lower plasma generator 8 and the air pump 7.

[0033] Both the upper plasma generator 6 and the lower plasma generator 8 use barrier discharge-DBD as their dielectric. Barrier discharge-DBD can generate plasma containing a large number of active particles, including ions, electrons, free radicals, ozone, and excited-state molecules. These active particles can destroy the structure and function of microorganisms, thereby achieving disinfection and sterilization. To ensure that the upper plasma generator 6 and the lower plasma generator 8 have a better disinfection and sterilization effect on the flowing air, the air pump 7 inside the outer casing 5 is positioned between the upper plasma generator 6 and the lower plasma generator 8.

[0034] Furthermore, considering the power supply issues of the upper plasma generator 6, the lower plasma generator 8, and the air pump 7, the top of the cover 2 is provided with a power supply interface 12 for supplying power to the plasma medical waste disinfection and sterilization device. The power supply interface 12 is connected to an external power source to supply power to the upper plasma generator 6, the lower plasma generator 8, and the air pump 7.

[0035] This utility model discloses a plasma medical waste disinfection and sterilization device. When collecting medical waste, the device first opens the lid 2 and inserts a garbage bag into the box body 1. Then, the lid 2 is closed, and each disinfection and sterilization column 4 is simultaneously inserted into the garbage bag. Medical waste is then added into the garbage bag by opening the upper cover plate 3. Next, each disinfection and sterilization column 4 is activated. The upper plasma generator 6, air pump 7, and lower plasma generator 8 of each disinfection and sterilization column 4 begin to work. Under the action of the air pump 7, the airflow flows sequentially through each disinfection and sterilization column 4, thereby circulating within the garbage bag. When the plasma generated by the upper plasma generator 6 and the lower plasma generator 8 comes into contact with the microorganisms in the medical waste, it destroys the structure and function of the microorganisms, thereby achieving the purpose of disinfection and sterilization.
