ABSTRACT:
A stethoscope shield system and method of preventing contamination of an instrument, particularly a stethoscope, includes a plurality of substantially planar shields stacked one upon the other, each of the shields having a substantially identical outer periphery and including a first surface and a second surface such that adjacent shields are attracted to one another with the first surface of each of these shields in contact with the second surface of an adjacent shield with a first shield of the plurality of shields being in contact with the diaphragm of the stethoscope for supporting the stacked shields, wherein the attraction force between the stacked shields occurs over less than an entire surface of at least one of the first and second surfaces and the attraction between the stacked shields has at least one of a consecutively increasing attraction area and a consecutively increasing attraction strength, and an exposed shield of the stacked shields is removed after contacting the body of a patient.
