Patent Images
1. A system for providing percussive respiratory therapy to a patient airway, the system comprising:
- a patient interface device having an inlet and an outlet fluidly connected to the patient airway; and
a driver unit for delivering gas flow to the inlet, the driver unit comprising;
an inlet line fluidly connectable to a source of pressurized gas,an outlet line fluidly connectable to the inlet of the patient interface device,at least one electronic valve having an inlet side fluidly connected to the inlet line and an outlet side fluidly connected to the outlet line,a controller electronically connected to the at least one electronic valve and configured to control operation of the at least one electronic valve in selectively delivering percussive pulses of gas flow from the inlet line to the outlet line.
