This invention relates to the field of chemical storage technology, specifically to a leak-proof hazardous chemical storage device. It includes a tank body with an upper plate and a lower plate concentrically fixed at its upper and lower ends, respectively. Multiple elastic plates are evenly distributed around the outer circumference of the tank body between the upper and lower plates. Each elastic plate has a fixing plate fixed to both ends in the circumferential direction. A sealed cavity is formed between the elastic plates, the tank body, the upper plate, and the lower plate. A protrusion is formed in the center of each elastic plate protruding outwards from the tank body. Swing frames are respectively installed on both sides of the protrusion, and pressure rollers are rotatably mounted on the swing frames, pressing against the elastic plates. This invention uses sensors installed within the sealed cavity to monitor leakage signals in real time, achieving rapid response; a motor-driven pressure roller compresses the elastic plates, making them adhere tightly to the leak point in the tank body to form a physical barrier; combined with the arc-shaped design of the fixing strips, it ensures a seamless seal, effectively blocking the leakage path of chemicals.

The invention relates to the technical field of radiopharmaceuticals and medical imaging, in particular to an STING-targeted precursor compound, a nuclide marker, a preparation method and application of the STING-targeted precursor compound, a nuclide marker, a pharmaceutical composition and application of the pharmaceutical composition. The STING targeting precursor compound, the pharmaceutically acceptable form of the STING targeting precursor compound, the nuclide marker of the STING targeting precursor compound and the pharmaceutically acceptable form of the STING targeting precursor compound have excellent in-vivo biological performance, can have high specific uptake in tumors or inflammations with high expression of interferon stimulating factors STING, has a high target-to-non-target ratio, and can be used for preparing the target-to-non-target tumor marker of the STING targeting precursor compound and the nuclide marker of the STING targeting precursor compound and the pharmaceutically acceptable form of the STING targeting precursor compound and the nuclide marker of the STING targeting precursor compound. And the non-specific background is low, and unnecessary radioactive injury can be reduced by lower non-target visceral organ uptake, so that the medication safety is high.
