Bowles stethoscope

The Bowles Stethoscope was developed by Robert C. M. Bowles who designed the diaphragm type of chestpiece on a stethoscope. He originally patented his design in 1894 and made several improvements to the design thereafter. The Bowles Stethoscope was designed so sound would not be obstructed and to detect high frequencies. The modern day Bowles Stethoscope we see often is the result of Robert C. M. Bowles and his improvements to the cammann binaural stethoscope.
