Description

TECHNICAL FIELD

[0001] The utility model application belongs to medical waste sorting technical field, concretely is a kind of medical waste sorting processing device. BACKGROUND

[0002] Medical waste refers to the waste generated in medical, preventive, health care and other related activities of medical and health institutions, which has direct or indirect infectivity, toxicity and other harmfulness. These wastes include used syringes, infusion tubes, cotton swabs, surgical dressings, discarded medicines, blood-stained gauze bandages and other types of items. Since they may carry a large number of bacteria, viruses and harmful substances, improper handling can pose a serious threat to the environment and human health.

[0003] It is necessary to sort medical waste. Different types of medical waste require different treatment methods. For example, infectious waste needs strict disinfection and incineration treatment to completely kill pathogens, while recyclable medical waste, such as some plastic products, can be recycled and reused after special treatment, reducing resource waste. If not sorted, mixing all medical waste for disposal will not only increase the cost of disposal, but also may result in incomplete disposal, failing to meet safety and environmental standards, and wasting recyclable resources.

[0004] In reality, medical waste sorting has gradually shifted from traditional manual operation to automation technology, with vision recognition system and mechanical hand collaborative sorting becoming the mainstream solution. The vision system usually uses high-resolution cameras and advanced image recognition technology. The camera takes a full range of pictures of the medical waste on the conveyor belt, obtaining shape, color, texture and other characteristic information of the waste. Then, the image recognition algorithm quickly analyzes and compares this information, matches the identified medical waste type with the pre-set database. For example, when the camera captures an object with features such as elongated and needle, the image recognition system can quickly determine that it is a syringe, which belongs to infectious medical waste. At this time, the mechanical hand moves to the corresponding position according to the instruction from the vision system, and accurately sorts the medical waste from the conveyor belt by clamping, adsorbing and other methods, and places it into the corresponding collection container. This vision and mechanical hand collaborative sorting method can improve the efficiency and accuracy of medical waste sorting, reduce the risk of direct contact with medical waste by manual operation, and also meet the needs of large-scale medical waste disposal.

[0005] However, in the actual scene of current medical waste sorting, the waste is generally transported to the processing site by a garbage truck, or directly dumped on the conveyor belt by relevant personnel to start the conveying process, and the sorting is completed by the cooperation of the visual recognition system and the mechanical hand. However, a large amount of medical waste is packed into a garbage bag when collected. In the dumping link, part of the waste will remain in the garbage bag. These garbage bags often have certain light-shielding and wrapping properties, causing the medical waste remaining in them to be shielded, making it difficult for the camera in the visual recognition system to obtain complete shape, color, texture and other feature information, and unable to accurately scan and analyze and compare, and then unable to accurately identify the type, so that the mechanical hand is difficult to effectively sort the part of the shielded medical waste according to the instruction, affecting the integrity and efficiency of the sorting. Therefore, a medical waste sorting and processing device is provided. Utility model content
