A disposable shield for stethoscope heads, preventing the transfer of disease or other contaminants by repeated use of the stethoscope. The shield or envelope is formed from a single piece of plastic material in which the sides are folded toward each other, thereby defining two top portions overlying a bottom portion. The edges are sealed as by heat sealing, thereby defining an envelope or shield. In a preferred embodiment, the shields are formed and maintained in a ribbon or array, maintained in the form of a roll within a container or the like. Adjoining shields are interconnected at the heat sealed areas which may be perforated for ease of separation.
