Description

Technical Field

[0001] The invention relates to the technical field of medical waste treatment, and in particular to a safe treatment and collection device for nuclear medicine waste. Background Art

[0002] Nuclear medicine waste refers to radioactive waste generated during nuclear medicine diagnosis, treatment and research. It includes radioactive isotopes, radioactive drug residues, radioactive liquid waste, etc. These wastes have the potential risk of radiation hazards and environmental pollution and need to be collected and safely handled. In order to avoid unnecessary radiation hazards caused by nuclear medicine waste, it is necessary to use external safe collection devices to safely collect and handle them. However, some existing safe collection devices still have some problems when used:

[0003] 1. When collecting and processing, most of the existing safety treatment and collection devices directly mix and collect the wastes, and then transfer them for treatment. This will cause solid waste and liquid waste to mix, which will increase the difficulty of subsequent treatment operations, and it is also easy to cause leakage and secondary pollution during transportation;

[0004] 2. When the existing safety treatment device is collecting and treating waste, during the process of dumping and loading the waste, the collection device is directly opened to come into direct contact with the outside air, which may lead to secondary pollution around during the dumping process, thus posing certain safety risks.
