Title:
MASK HAVING ATTACHED TEMPERATURE-SENSITIVE STICKER FOR PREVENTING COVID-19
Document Type and Number:
WIPO Patent Application WO/2022/092388
Kind Code:
A1
Abstract:
The present invention relates to a COVID-19 prevention mask, wherein a temperature-sensitive sticker attached to the mask changes color when the body temperature of the face exceeds 37°C, thus making it possible to quickly and easily determine whether a patient who has a high fever and is wearing the mask has COVID-19. Therefore, the mask is convenient for users to use. This temperature-sensitive mask for preventing COVID-19 has a through hole formed therein, and has a sticker body, capable of measuring body temperature, attached to the through hole. The sticker body comprises: a soft PVC thin white film sheet containing 0.05-0.01% of silver nano powder; a danger indication printed layer printed in the center of the soft PVC thin white film sheet and displaying characters or patterns indicating 37.5 or danger group; a black background display printed layer which is printed in black over the entire surface of the danger indication printed layer and is composed of a thermochromic pigment that becomes transparent in response to temperatures of 37.5±0.5; a yellow printed layer which is formed on an upper portion of the black background display printed layer and is composed of a yellow thermochromic pigment that becomes transparent in response to temperatures of at least 37.5±0.5; a transparent coating layer formed on an upper portion of the printed layer; an adhesive layer, formed on a boundary surface, for attaching to the mask surface; and a release paper, and thus can be easily attached by anyone. Thus, the temperature-sensitive mask for preventing COVID-19 is a very useful invention that makes it possible to easily identify patients with high fever.
