Abstract
A percussive aid provides percussive force to aid in the treatment of Cystic Fibrosis and other pulmonary blockage diseases. The device includes a frame with a pair of reciprocating arms mounted thereto at one of their ends. The other end of the arms mount impactor cups. A spring is associated with each of the cups. A drive mechanism is carried by the frame and moves the arms through a predetermined path of travel from a first uncocked position to a second cocked position of maximum deflection wherein the spring is placed in tension when the arm is tripped.
