Description

Technical Field

[0001] The utility model relates to the technical field of medical nuclide diagnosis and treatment, in particular to an automatic radionuclide packaging device. Background Art

[0002] Medical isotope drugs are radiation sources due to their physical and chemical properties and have strong ionizing radiation. Common medical liquid radionuclides include iodine-131, technetium-99, 18F-FDG, lutetium-177, etc. They are mostly used in the diagnosis and treatment of tumors. When using them, the staff usually calculates the required volume based on the concentration of the radioactive drug in a protective fume hood or ventilated hot room. Then, they manually extract the corresponding volume of radioactive drug from the syringe with a syringe, measure the dose in the activity meter, and finally repeatedly calibrate until the required accurate dose is extracted. Then, they take out the syringe, put on the syringe tungsten alloy protective cover, and inject the patient. After the injection, it is necessary to measure the remaining syringe again to input the accurate dose for subsequent accurate inspection.
