Diagnostic reagent preservation device for diagnosing Alzheimer disease

The utility model provides a diagnostic reagent preservation device for diagnosing Alzheimer's disease, which comprises a fixedly connected main body and a ventilation mechanism arranged on the outer side of the main body in a matched manner, one side of the top end of the main body is connected with a sealing cover in an overturning manner, a preservation structure is embedded in the main body, and a limiting layer structure is arranged in the main body. The preservation structure is embedded into the limiting layer structure at the same time, and the preservation structure and the limiting layer structure are both vertically embedded into the main body. The effect of limiting and surrounding an external reagent is achieved through an upper preservation plate and a lower preservation plate, rectangular outer protrusions arranged at the two ends are embedded into two corresponding limiting layer structures, the effect of limiting and fixing the whole preservation structure in a main body is achieved, the effe
