ABSTRACT:
A stethoscope includes a pair of branches, each having a bent clip tube section with a coupling end portion connected to an ear tube section, and a curved intermediate fulcrum portion, which interconnects the coupling end portion and a resilient operating end portion and which has a concave outer surface that faces away from the other branch, and a convex inner surface that faces toward the other branch. A rubber tube is connected to the operating end portions of the clip tube sections of the branches and is in fluid communication with the branches. The intermediate fulcrum portions abut against each other. The operating end portions form a press space therebetween, and are depressible toward each other when removing the ear tube sections from the ears of the wearer.
