ABSTRACT:
A medical appliance for use in percussive respiratory therapy comprises a partially enclosed cavity which presents a substantially circular opening bordered by an annular ring of moldably compressible material for effecting a pneumatic seal of the cavity to a body area against which it is placed. The annular ring defines a groove to communicate with a curling semi-circular lip, the ring also defining a cavity filled with a compressible gaseous vapor for cushioning the impact of the appliance with a patients's body.
