Abstract:
A vaccine container having a failure indicator (3) and a failure indication method thereof, the vaccine container comprising a vaccine bottle (1), the failure indicator (3) and a failure indicator box (4). The failure indicator box (4) has a sealed cavity structure, and the failure indicator (3) is placed in a cavity of the failure indicator box (4); and the failure indicator box (4) is fixedly connected to the vaccine bottle (1). The failure indicator (3) is obtained by uniformly mixing a component A and a component B; a raw material of the component A comprises a phase change heat storage material, an alkali solution and an emulsifier; a raw material of the component B comprises the same phase change heat storage material as the component A, a phenolphthalein indicator and an emulsifier; and the phase change temperature of the phase change heat storage material is 2-8°C. The vaccine container having the failure indicator (3) may absorb heat in the environment, control the temperature rise of a vaccine, and improve the stability of a vaccine transportation process, and when the temperature exceeds 8°C, the failure indicator (3) turns red, so that whether the vaccine fails or not may be indicated, and the safety of the vaccination is thus ensured.
