The Harvey Double Head Stethoscope was part of a collection of stethoscopes by the Welch Allyn company called "Original Harvey Stethoscopes". They are no longer sold, and were replaced by the Harvey DLX stethoscopes.
US Patent No. 3,109,508 was granted on November 5th, 1963, to Ralph Cefaly, and was for an acoustic stethoscope with three heads: a bell, a diaphragm, and a corrugated diaphragm.
In the mid-1950s, Dr. Watkins Proctor Harvey invented this three-headed stethoscope, the Harvey Stethoscope, and it was produced by the Cefaly Research Corporation of Brentwood, Maryland. It was sometimes known as the Harvey Cefaly Stethoscope. The corrugated diaphragm helps detect faint heart activity and a larger range of frequencies. The bell is especially good for detecting low frequency sounds. Low frequency heart sounds called gallops can be signs of heart disease, and are important to be able to detect.
