ABSTRACT:
A stethoscope having a separable connection in the sound conducting tube permits the removal and attachment of various sound receiving portions. The connection has a first coupler attached to one free end of the sound conducting tube, and a second coupler attached to the other free end of the sound conducting tube. Each of the couplers is attached to the outer surface of the tube to avoid altering the inner diameter of the tubes in the vicinity of the connection. Maintaining the original diameter of the inner tube surface prevents adverse effects on the transmitted sound as it passes through the connected tube sections and reduces wear at the tube end. The first and second couplers are held together by suitable mechanical or magnetic attachment means that permit quick and easy separation of the couplers.
