ABSTRACT:
A stethoscope is fitted with a disposable cover to prevent cross contamination between patients. The cover is formed as a shield of material which is impermeable to liquids but which transmits sound waves. Adhesive is applied in a predetermined pattern on a portion of the cover so as to define a non adhesive fluid pathway between the central portion of the cover and its peripheral edge. This pathway adapts the cover for use with stethoscopes having vented diaphragms. Additional cover configurations are provided for use on the bell of a stethoscope.
