Air pulse generator

An air control assembly for an airway clearance system, comprising:

• a casing;
• first and second pistons disposed within the casing;
• a connector assembly coupled to each of the first and second pistons;
• and
• a motor assembly operably coupled to the connector assembly, wherein the motor assembly includes:
• a motor operably coupled to the connector assembly, wherein the connector assembly is configured to translate rotational motion from the motor to linear motion of the first and second pistons between expanded and retracted positions to oscillate air within the casing;
• a bracket coupled to the motor;
• and a dampener disposed between the bracket and the casing to reduce translation of vibrations caused by the motor to reduce noise generation;
• wherein the connector assembly includes:
• a first connecting rod coupled to the first piston via a first hinge assembly;
• a second connecting rod coupled to the second piston via a second hinge assembly;
• and
• dampening pads disposed between the connector assembly and each of the first and second pistons to reduce vibration translation between the connector assembly and the first and second pistons, respectively.

An airway clearance therapy system, comprising:

• a blower;
• an air pulse generator operably coupled to the blower, the air pulse generator including:
• a casing defining an interior chamber;
• first and second pistons disposed within the interior chamber
• a connector assembly coupled to the first and second pistons, wherein a first connecting rod is coupled to the first piston and a second connecting rod is coupled to the second piston, and wherein the first connecting rod is coupled to the second connecting rod;
• and
• dampening pads disposed between the connector assembly and the first and second pistons, respectively;
• a motor assembly operably coupled to the connector assembly, wherein the connector assembly translates rotational motion from the motor assembly to linear motion of the first and second pistons to generate air pulses;
• and
• a dampener is disposed between the motor assembly and the casing to reduce vibrations transferred between the motor assembly and the casing.
