Embodiment Construction

[0018] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The invention provides a temperature and time record mark.

[0020] refer to figure 1 , figure 1 It is the first embodiment of the present invention. In this embodiment, the temperature and time record mark includes a base layer 300, a phase change layer 100, an indication layer 200, and a display layer 400. The phase change layer 100 and the indication layer 200 are located at On the same plane, the phase change layer 100 is located at one end of the temperature and time recording mark, and the indicating layer 200 is located at the other end of the temperature and time recording mark. The indicating layer 200 has a capillary structure. When the ambient temperature is greater than or equal to the phase change critical value of the phase change layer 100, the phase change layer 100 penetrates into the indicat...

Abstract

The invention discloses a temperature and time recording mark which is attached to a to-be-refrigerated article, such as vaccine. The temperature and time recording mark comprises a phase change layer and an indicating layer; when an environmental temperature is more than or equal to a phase change critical value of the phase change layer, the phase change layer permeates to the indicating layer and the indicating layer is in irreversible color change following the permeation of the phase change layer; when the environmental temperature is less than the phase change critical value of the phase change layer, the phase change layer stops permeation and the indicating layer stops color change; the phase change layer is matched with the indicating layer, so that if the to-be-refrigerated article, such as vaccine, is beyond the storage temperature can be monitored in real time, the total time of the to-be-refrigerated article, such as vaccine, located in the environment beyond the storage temperature can be determined according to the condition of the color change of the indicating layer, and if the to-be-refrigerated article, such as vaccine, is invalid also can be judged.

Description

technical field [0001] The invention relates to the field of temperature recording, in particular to a temperature and time recording mark. Background technique [0002] As we all know, products in some fields need to be stored in a specific temperature environment. When the ambient temperature changes, the performance of the product will be affected. Taking vaccines as an example, most vaccines are stored in an ambient temperature range of 2-8 degrees. If the external ambient temperature value exceeds the storage temperature range for a certain period of time, the vaccine will become invalid, and the inoculation of the invalid vaccine will bring harm to the human body. Serious side effects, and even cause fatal accidents. [0003] At present, the domestic monitoring of the temperature of the environment where the product is stored is mainly achieved through manual measurement and paper records. The data lacks real-time and coherence, and it is impossible to monitor the ent...
