ABSTRACT:
A stethoscope with a figure-eight configuration designed for one-handed operation and further comprising improvement to the headpiece resonance chamber. The ear tubes of the stethoscope are roughly S-shaped and together form a figure eight design. The lower portion of each ear tube is connected by a resistant force mechanism that maintains the stethoscope in the closed configuration. By applying one-handed compressive force to the resistant force mechanism attached to the lower portion of the stethoscope's figure-eight construction, the earpieces are separated and the stethoscope adopts the open configuration. Both the headpiece and the diaphragm are interchangeable to allow a variety of different shapes and sizes.
