Description

Technical Field

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

[0002] In today's booming healthcare industry, the proper disposal of medical waste has become a crucial aspect of public health and safety. Medical waste contains a large number of pathogens, viruses, chemical pollutants, and other harmful substances; improper handling can lead to serious environmental pollution and the spread of disease. Traditional medical waste disposal methods mainly rely on centralized treatment facilities in fixed locations; however, this centralized treatment model has many limitations.

[0003] On the one hand, the timely collection and transportation of medical waste faces significant challenges in scenarios such as public health emergencies, field medical rescue, or medical activities in remote areas. The risk of medical waste backlog increases dramatically, potentially leading to the leakage of hazardous substances or the breeding of more pathogens due to prolonged storage, threatening the surrounding environment and public health. On the other hand, the high construction costs of fixed treatment facilities, including land acquisition, plant construction, and the installation and commissioning of large-scale specialized equipment, make them unaffordable for many regions, especially economically underdeveloped areas, resulting in an uneven regional distribution of medical waste treatment capacity.

[0004] To address these challenges, some vehicle-mounted medical waste disposal equipment has emerged. However, existing equipment has limited functionality, limited disinfection methods, and low and incomplete processing efficiency, making it difficult to meet the growing and diverse needs for medical waste disposal. Some equipment is highly dependent on the vehicle chassis during operation, which cannot be flexibly deployed, resulting in low resource utilization. If the vehicle malfunctions or requires repair, the entire medical waste disposal process is easily disrupted, affecting emergency response efficiency.

[0005] Given the drawbacks of traditional medical waste disposal methods and the inadequacies of existing vehicle-mounted equipment, it is particularly important and urgent to propose an integrated, high-efficiency, flexible, and convenient medical waste disinfection vehicle technology solution. Its aim is to achieve rapid, safe, and thorough disinfection of medical waste in different scenarios, improve the emergency response capabilities and resource utilization efficiency of medical waste disposal, fill existing technological gaps, and bring innovative solutions to the field of medical waste treatment.

[0036] Example 1:

[0037] Combined with appendix Figures 1-3 A medical waste disinfection vehicle includes a vehicle chassis 1, a container 2, and telescopic outriggers 3. The vehicle chassis 1 plays a crucial role in the transportation system, primarily functioning to transfer the container 2. This design fully meets the needs of various emergency situations, such as in the field, and possesses the ability to quickly transfer the vehicle to a designated location for medical waste disinfection and treatment based on actual operational requirements.

[0038] The container 2 is detachably connected to the vehicle chassis 1 via locking pins. Telescopic outriggers 3 are installed at each of the four corners of the container 2. When it is necessary to separate the container 2 from the vehicle chassis 1, the telescopic outriggers 3 provide support, firmly holding the container 2 in place. Especially when the container 2 needs to remain in one location for an extended period, the procedure is as follows: first, open the locking pins; then, use the telescopic outriggers 3 to support the container 2, separating it from the vehicle chassis 1. After the vehicle chassis 1 has driven away, the telescopic outriggers 3 are shortened to allow the container 2 to land smoothly, ensuring the stability and safety of the entire process. Simultaneously, after the vehicle chassis 1 has been separated and driven away, it can be flexibly reassigned for other transport tasks. This design effectively improves the utilization rate of the vehicle chassis 1, achieving optimal resource allocation.

[0039] Inside the container 2, a system specifically designed for the disinfection and treatment of medical waste is installed. Specifically, the container 2 contains, in sequence, a pulverizing device 4, a first spiral conveyor 5, a disinfection device 6, and a second spiral conveyor 7. Since the pulverizing device 4, the first spiral conveyor 5, and the second spiral conveyor 7 are all commercially available and mature device types, their specific structural composition and working principles will not be elaborated upon in this embodiment.

[0040] In terms of layout, the first spiral conveyor 5 is installed directly below the pulverizing device 4, with its inlet precisely corresponding to and connected to the outlet of the pulverizing device 4. A buffer chamber structure is cleverly designed between them. During operation, the pulverizing device 4's main function is to pulverize medical waste into small particles or fragments, which are then temporarily stored in the buffer chamber. Next, the first spiral conveyor 5 is responsible for stably and evenly conveying the pulverized medical waste stored in the buffer chamber to the sterilization device 6 according to pre-set quantitative parameters for subsequent sterilization. A second spiral conveyor 7 is positioned below the sterilization device 6, with its inlet precisely corresponding to and connected to the outlet of the sterilization device 6. After sterilization by the sterilization device 6, the medical waste is output to the outside of the housing 2 via the second spiral conveyor 7, facilitating subsequent unified collection and centralized processing.

[0041] Further analysis of the structural details of the disinfection device 6 reveals that it mainly comprises a housing 6-1. An inlet is designed at the top of the housing 6-1, which precisely corresponds to and connects with the outlet of the first screw conveyor 5, ensuring smooth material entry into the disinfection process. The interior space of the housing 6-1 houses three different types of disinfection components: a microwave sterilization device, a steam sterilization device, and a UV sterilization device. It should be noted that the microwave sterilization device, steam sterilization device, and UV sterilization device are all common standard disinfection equipment types available on the market. By organically combining these three disinfection methods for synergistic operation, the overall disinfection effect for medical waste can be significantly improved, ensuring the thoroughness and reliability of the disinfection process.

[0042] A discharge port is designed at the bottom of the housing 6-1. A sliding plate 6-2 is installed at the corresponding location of the discharge port using a movable insertion method. Its main function is to close the discharge port of the housing 6-1 when necessary, preventing premature leakage of materials. Simultaneously, a telescopic cylinder 6-3 is installed on the outside of the housing 6-1. The drive end of the telescopic cylinder 6-3 is connected to the sliding plate 6-2, thereby achieving precise control over the opening and closing of the sliding plate 6-2. During the process of the first screw conveyor 5 conveying the pulverized medical waste into the housing 6-1, the sliding plate 6-2 is closed by the telescopic cylinder 6-3, allowing the medical waste to be temporarily stored inside the housing 6-1. This ensures that it receives sufficient time for disinfection and sterilization, guaranteeing that the disinfection effect meets the predetermined standards.

[0043] In addition, a stirring shaft 6-4 is rotatably connected inside the housing 6-1, with multiple stirring blades arranged regularly around its shaft. A motor 6-5 is installed outside the housing 6-1, its output shaft connected to the stirring shaft 6-4 via a compatible drive connection. During the sterilization process, the motor 6-5 starts and drives the stirring shaft 6-4 to rotate. The rotation of the stirring blades thoroughly agitates the medical waste inside the housing 6-1, ensuring uniform contact between the waste and the sterilization medium, thus significantly improving the sterilization effect. Once the sterilization process reaches the preset time, the telescopic cylinder 6-3 drives the slide plate 6-2 to open, allowing the sterilized medical waste to be smoothly discharged to the outside of the housing 2 via the second spiral conveyor 7, preparing for subsequent collection and centralized processing.

[0044] Example 2:

[0045] Referring to Figures 1 and 2, the alternative medical waste disinfection vehicle provided by this utility model differs somewhat from Embodiment 1 in its overall structural design. Specifically, compared to Embodiment 1, in this second embodiment, a lifting device 7 specifically for lifting the waste bin is added to the position of the container 2 corresponding to the crushing device 4. The lifting device 7 used here is also a commercially available and mature type of device. Its core function is to efficiently lift the waste bin containing medical waste and accurately pour the medical waste inside the waste bin into the crushing device 4. By introducing this lifting device 7, the labor intensity of operators can be significantly reduced during actual operation, the work efficiency of the entire medical waste treatment process can be improved, and the safety and convenience of the operation process can also be enhanced.

[0046] The internal structure of the enclosure 2 was further optimized. A relatively independent power compartment was created within the enclosure by strategically placing partitions. A generator 8 is installed inside this power compartment. When the enclosure 2 is stationary independently, i.e., separated from the vehicle chassis 1 and stationed at a fixed work location, the generator 8 assumes the responsibility of providing stable power support for the normal operation of all equipment inside the enclosure 2. This ensures that disinfection work and the operation of other related equipment are not affected by power supply issues and can proceed continuously and stably.

[0047] In addition, an air purification device 9 is installed inside the container 2, which also adopts a mature technology solution currently available on the market. During medical waste disinfection operations, the air purification device 9 is activated simultaneously, effectively purifying the air inside the container 1 and the surrounding area. This design significantly reduces the environmental pollution risk that may be caused by exhaust gas leaks, effectively protecting the surrounding environment and the health of operators. It makes the entire medical waste disinfection process more environmentally friendly, safe, and reliable, meeting the requirements of modern environmental protection concepts and relevant health and safety standards, and has high practical value and promising prospects for widespread application.

[0048] The parts of this utility model not described in detail are prior art. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and are intended to include all changes that fall within the meaning and scope of equivalents within this utility model.
