Abstract
An airway clearance therapy system includes a blower and an air pulse generator coupled to the blower. The air pulse generator includes a casing defining a chamber, first and second pistons disposed within the chamber, and a connector assembly coupled to the first and second pistons. A first connecting rod is coupled to the first piston, and a second connecting rod is coupled to the second piston. The air pulse generator also includes dampening pads disposed between the connector assembly and each of the first and second pistons. A motor assembly is operably coupled to the connector assembly. The connector assembly translates rotational motion from the motor assembly to linear motion of the first and second pistons to generate air pulses. A dampener is disposed between the motor assembly and the casing to reduce vibrations transferred between the motor assembly and the casing.
