The MD-1 (Latin Serbian: Maska Dečija — "Child Mask") is a respirator designed for children, manufactured by Miloje Zakić in Kruševac, Yugoslavia (now in Serbia) mostly in the later part of the 1980s.
The MD-1 was manufactured as a result of the decision of the Federal Executive Council of Yugoslavia (Official gazette 3/83) to establish resources for personal and collective protection against war and other dangers.
