ABSTRACT:
A stethoscope shield unit comprising a plurality of substantially planar shield stacked one upon the other, each of the shields including a first surface having an adhesive applied thereto and a second surface such that adjacent shields adhere to one another with the first surface of each of these shields adhering to the second surface of an adjacent shield with a first shield of the plurality of shields being adhered to the diaphragm of the stethoscope for supporting the plurality of shields wherein an exposed shield of the plurality of shields is removed after contacting the body of a patient. A protective shield devoid of an adhesive may be positioned adjacent the first shield of the plurality of shields with the protective shield being removed prior to adhering the first shield of the stack to the diaphragm. A method for preventing contamination of an instrument, particularly a stethoscope includes the steps of applying a plurality of substantially planar shields stacked one upon another to the surface of the stethoscope, each of the shields including a first surface having an adhesive applied thereto and a second surface such that adjacent shields adhere to one another with the first surface of each of the shields being adhered to the second surface of an adjacent shield and the first surface of a first shield in the stack adjacent the surface is adhered to the surface and subsequently removing an outermost shield of the stack after application of the instrument to each sequential patient.
