  • Protective cover for a contact surface for a stethoscope
    Patent number: 5808244
    Abstract: A protective cover for a contact surface of a stethoscope having a planar section of film material with a static charge placed therein. The planar section of film material has a top surface and a bottom surface. The section of film material has an area greater than the contact surface of the stethoscope. The top and bottom surfaces are non-adhesive surfaces. The static charge acts on the bottom surface so as to allow the bottom surface to removably cling to the contact surface of the stethoscope. The planar section of film material is applied to a backing surface having an area greater no less than the area of the section of film material.
