ABSTRACT:
A stethoscope device assembly which is adapted to monitor a surface sound on a body surface of a mammalian body and includes an earpiece assembly which is acoustically coupled to a sound receiver assembly. A sound transmission member is coupled to and extends between the earpiece assembly and the sound receiver assembly. An arm which includes at least a portion of the sound transmission member and also a superelastic member is coupled to and extends between the earpiece assembly and the sound receiver assembly. The superelastic member has a resting shape, such as a helical shape, which is adjustable under an applied force to a strained shape, and also has an elastic memory to the resting shape after being adjusted to the strained shape. The resting shape of the superelastic member minimizes the arc about which the sound receiver assembly may swing when the stethoscope is worn by a user such that the earpiece assembly is engaged to the user's head or neck and the arm extends vertically downward therefrom along the user's chest. A transducer diaphragm is removably engageable with a housing of the sound receiving assembly and also bears visible indicia which is adapted to pacify an apprehensive patient. A plurality of the transducer diaphragms is provided, each having a different indicia than the other transducer diaphragms such that a patient or healthcare provider/user of the stethoscope may chose one of the transducer diaphragms based upon its respective indicia.
