Patent ID: RE40814

Claim:
An apparatus for generating oscillatory air pulses in a bladder positioned about a person, comprising: an oscillatory air flow generator, comprising: an air chamber; a reciprocating diaphragm operably connected with the air chamber, a rod having a first end and a second end, the first end operably connected with the diaphragm, and the rod extending generally orthogonal to the diaphragm; a crankshaft operably connected with the second end of the rod and extending generally orthogonal to the rod; and a first motor operably connected with the crankshaft; a continuous air flow generator operably connected with the oscillatory air flow generator; a first feedback and control means operably connected with the oscillatory air flow generator for maintaining the a frequency of the oscillatory air flow generator at a predetermined value; and a second feedback and control means operably connected with the continuous air flow generator for continuously varying the an output pressure of the continuous air flow generator in order to maintain the a peak pressure generated by the positive continuous air flow generator at a predetermined value.
