CLOSE BABY / Medical products


If the mask is worn too long, it may lead to infection with other bacteria again. If the mask is worn too short, it will not only have no protective effect, but also lead to a great waste of more medical resources because it is discarded too early.
Close baby - uses non-toxic and tasteless thermochromic memory material, which is close to the skin. Through the induction of temperature and humidity in the use of breathing, it can achieve the function of visual discoloration warning, and help the elderly and children replace masks in time.
