Cold-chain overtemperature monitoring device and manufacturing method thereof

Abstract

The invention relates to a cold-chain overtemperature monitoring device and a manufacturing method thereof, and belongs to the technical field of temperature monitoring. The cold-chain overtemperaturemonitoring device comprises a casing and a detection piece positioned in the casing, the detection piece comprises a deformation indication part and a fixed part, the fixed part is fixed in the casing, and the casing is provided with a viewing port; and during work, when the deformation indication part detects that the spatial temperature in the casing exceeds a preset temperature, the deformation indication part is deformed, and a deformed portion of the deformation indication part is exposed in the observation port of the casing. The cold-chain overtemperature monitoring device can be directly placed on a package of an article which needs refrigeration, temperature monitoring and overtemperature early warning are realized for each minimal independent refrigeration article, a monitoringresult can be distinguished easily by naked eyes, energy and manual control are not needed, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of temperature monitoring, and in particular relates to a cold chain over-temperature monitoring device and a manufacturing method thereof. Background technique [0002] The vast majority of blood biological products such as vaccines need to be transported and stored in the whole cold chain from production to injection to ensure their normal efficacy. Once the storage temperature is exceeded in any process before injection, there is a risk of failure of vaccines and other biological products, which will not only fail to achieve the desired effect of epidemic prevention, but also increase the risk of infection, which will endanger life safety in severe cases. [0003] Therefore, it is necessary to monitor the temperature of the storage environment during transportation and storage. Most of the existing cold chain temperature monitoring systems use monitoring devices based on electronic systems. The temperatu...

Problems solved by technology

[0005] In the existing technology, the cold chain temperature monitoring system is costly and the control system is complicated. Most of them can only monitor the temperature of the transport vehicle and the internal environment of the refrigerator, and cannot monitor each independent refrigerated product. At the same time, due to technical It is impossible to accurately judge whether the refrigerated product has experienced over-temperature failure
