摘要

Procedure for the control of the sterilization of dressings and/or analogous materials by means of the perennial or not transmutation of pure or combined substances characterized by the fact that taking advantage of the physical peculiarity of the substances to be transmuted at certain melting temperatures liquefaction or chemical reaction one or more substances whose melting degrees are comprised between 100º and 200º c. Are arranged, such as atropine chloroaurate 197º silver nitrate 198º bromovalerilurea 147º-149º colophony 100º arecoline bromhydrate 170º-171º phthalic anhydride 128º pirogalol 132º or others within a suitable container to whose substances, when appropriate, is added the mineral or organic coloring matter placing said container inside or outside the cans or containers containing the dressings containing the materials to be sterilized in the autoclave or appropriate sterilization apparatus and receives heat and tra if the substance placed inside the container is changed, it indicates that the heat has reached the previously known point of transmutation of that introduced substance and therefore that the sterilization of the material to be sterilized has taken place.
