First Claim
Patent Images
1. A high frequency chest wall oscillation (HFCWO) therapy system, the HFCWO system comprising:
- an inflatable garment to be worn by a person;
an air pulse generator operable to produce oscillating pressure pulses that are communicated to the inflatable garment, the air pulse generator having a housing, a first diaphragm plate and a second diaphragm plate supported in the housing and moved reciprocally back and forth to produce the oscillating pressure pulses, wherein the first and second diaphragms plates each have a substantially circular outer periphery, wherein the air pulse generator further comprises an air chamber shell having first and second substantially circular openings at opposite ends thereof and first and second flexible diaphragm seals that extend between the substantially circular outer peripheries of the respective first and second diaphragm plates and the respective substantially circular first and second openings provided in the housing, the first and second diaphragm seals having an arched shape spanning between the substantially circular outer peripheries of the respective first and second diaphragm plates and the respective substantially circular first and second openings provided in the housing such that the first and second diaphragm seals bulge away from an air space defined by the air chamber shell; and
at least one hose to interconnect the air pulse generator with the inflatable garment, the hose communicating the oscillatory pressure pulses from the air pulse generator to the inflatable garment, wherein the air pulse generator is sized, shaped, and configured so as to occupy a volume no greater than about 1,200 in.3 and to weigh no more than about 17 lbs.
