Problems solved by technology

[0005] The purpose of the present invention is mainly aimed at the existing cold chain link of vaccines. Due to the lack of effective identification means, it is impossible to identify whether the vaccine is invalid due to temperature changes, and at the same time, the existing VVM label reading method is backward.

Embodiment Construction

[0028] Such as figure 1 As shown, it is a schematic diagram of an embodiment of a thermochromic barcode label of the present invention. The thermochromic barcode label includes: a thermochromic area and a product information area, wherein the thermochromic area is composed of a VVM thermal label Composed, the reaction principle is that the substituted diacetylene (Diacetylene) monomer undergoes a color change after solid-state polymerization, and the product information area is a barcode, including product information such as the product manufacturer, production time, and production address.

[0029] VVM is the result of long-term investment in research and development by the World Health Organization and UNICEF. It was first applied to oral polio vaccine in 1996, and has been gradually applied to other vaccines since 2002. At present, VVM has been routinely applied to vaccines procured by WHO and UNCIEF. Overseas vaccine giants have become the main users of VVM, and more and ...

Abstract

The present invention provides a thermochromic material bar code tag and a reading method thereof. The thermochromic material bar code tag is a tag configured to mark vaccine product information and storage state, and comprises a thermochromic area and an area comprising product information, and the thermochromic area is formed by VVM (Vaccine Vial Monitor) thermal tags. A reading device is employed to read the thermochromic material bar code tag to achieve one-step reading of the product production information and the storage state information, accelerate the input process of vaccine cold chain transportation and cold chain information, improve the input accuracy and avoid the problem that workers are fatigable and low in efficiency in a batch reading mode.

Description

technical field [0001] The invention relates to the field of barcode reading, in particular to a thermochromic barcode label and a reading method thereof. Background technique [0002] Vaccines are an important means for humans to fight diseases, but vaccines need to be stored at low temperatures. Once the vaccine is overheated, it will fail at least, or cause harm to the human body at worst. Inoculation of vaccines that have not been stored in the cold chain at 2°C-8°C or expired vaccines, the primary risk after injection is ineffective immunity. For example, fatal infectious diseases such as rabies can prevent death through vaccination, but vaccination with problematic vaccines Leading to ineffective immunity, the vaccinators may be infected and die. There have been incidents in China where rabies vaccines were ineffective and resulted in the death of the vaccinators. The secondary risk is that the vaccine may be contaminated or antigenically denatured due to improper st...
