In recent years, with the civilized popularization of nuclear technology application, pharmaceutical enterprises and hospitals, particularly production devices for radionuclides such as single photon pharmaceuticals (SPECT imaging agents/Tc-99 m) and the like, lack production protection devices meeting GMP certification requirements only from the perspective of radiation safety, and the drug production environment cannot meet the requirements of grade a and positive pressure required by GMP certification, so that the quality of the produced drugs has great potential safety hazards. The hidden dangers are not only local problems of laboratories, but also environmental safety (such as leakage and discharge of hazardous substances) and social safety (such as escape and loss of dangerous goods) are involved, and a warning clock is sounded to safety protection problems of various levels of biosafety laboratories and biomedical laboratories, so that high attention of governments of various countries in the world is attracted, and the hidden dangers become the focus of general attention all over the world.
In the prior art, the marking and the subpackaging of medical isotope medicines (such as radionuclides containing Tc-99m, F-18, I-131 and the like) are finished in one or more different independent operation cabinets, and after the isotope medicines are marked in one operation cabinet, the isotope medicines need to be taken out and taken into another cabinet to finish the subpackaging, so that the working procedure of radiation workers is complicated, and the contamination probability of the radionuclides is increased.
The protection cabinet applied to SPECT developer marking and subpackaging in the current market mainly relates to the following two structural schemes:
the first method comprises the following steps: the simple production line is formed by adopting one or more ventilation protection cabinets with hundred-grade positive pressure, the structure is simple, the market share is high, the procedures of leaching, marking and subpackaging are sequentially completed in the protection cabinets during production, leacheate and marking liquid are transferred to another protection cabinet temporarily from the protection cabinet, so that the purification grade jump phenomenon exists in medicine transfer, and the whole medicine production process cannot be guaranteed to be in an A-grade positive pressure production environment.
And the second method comprises the following steps: the ordinary negative pressure sealing ventilation protection cabinet is adopted, although the structure is simple, the structure is only used for the operation of volatile nuclide, the production environment of hundred-level positive pressure required by the production of SPECT developer under GMP certification condition cannot be met, the medicine safety cannot be guaranteed, and safety accidents are easily caused.
