Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging, in particular to a radioactive medicine quantitative packaging system. Background Art

[0002] Radiopharmaceuticals refer to radionuclide preparations or their labeled compounds used for clinical diagnosis or treatment. The difference between radiopharmaceuticals and other drugs is that the radionuclides contained in radiopharmaceuticals can emit radiation. Therefore, all drugs containing radionuclides in molecules or preparations are called radiopharmaceuticals. Radiopharmaceuticals come in many forms, and a packaging system is required when dealing with the packaging of powdered radiopharmaceuticals.

[0003] The Chinese utility model patent with patent number CN220412884U discloses a radioactive drug dispensing instrument. Through the joint action of a bellows, a hair dryer, a filter, and an air outlet, the negative pressure in the box can be guaranteed to be normal, so as to avoid the volatilization of drugs into the working environment when the exhaust is not smooth, causing the background of the room air to increase, thereby preventing medical staff from being exposed to radiation, especially preventing internal irradiation caused by inhalation. When the hair dryer arranged in the bellows rotates, the air flows, and a filter is arranged at the lower end of the hair dryer. Therefore, when dispensing, the radioactive drug is filtered from the filter, which effectively intercepts the harm of the volatilization of the drug to the medical staff, thereby improving the safety of the equipment.
