REMINDER mask / Medical equipment


Many people fail to use masks correctly. In order to remind people to change masks regularly, prevent masks from being reused and stop masks from causing secondary infection, we decided to redesign masks. We add a wet-sensitive material to a common medical mask. After four hours of use, the mask will gradually change from blue to an unusable gray, with a gruesome coronavirus pattern, to remind users to change it. And we put a small ring and an elastic rope into the mask. After using the mask users can first pull out the inner ring and then pull out the upper pull rope, sealing the outside of the mask exposed to the virus environment.
