Description

Technical Field

[0001] The utility model relates to the technical field of medical nuclides, in particular to a radioactive nuclide subpackaging and infusion device. Background Art

[0002] Medical radionuclides are radionuclides that can be used for medical imaging, functional measurement and treatment. The methods are simple, sensitive, accurate, safe and effective. They are an indispensable and important tool in modern medicine. However, radionuclides need to be packaged before use to facilitate subsequent medical use.

[0003] The existing radionuclide packaging and infusion devices still have some problems when in use. First, when some existing devices are packaging and infusing, some of them use a rotating tray or a manipulator clamping device to move the liquid storage tube on the tray to the bottom of the designated needle before dispensing. Such operation easily reduces the stability during injection, and the operation method is also relatively inconvenient, which reduces the efficiency of the device. Secondly, during the dispensing process of the existing devices, the residual liquid on the needle is easy to drip when the needle is injected, or liquid overflows during injection, which not only causes waste, but also brings inconvenience to cleaning.
