Abstract
A pressurized air supply source for a portable nasal irrigator houses an airflow regulating system, instead of external bulky, heavy components, to power the atomization of fluid for irrigation of nasal passages. The airflow regulating system is made up of a pump, a motor to drive the pump, a filter with an inlet air manifold connected to the pump to eliminate additional tubing within the pressurized air supply source, and an optionally rechargeable battery to drive the motor. An external AC/DC power supply may charge the battery or operate the device when the battery is in a discharged state. A canister for holding fluid attaches on top of the pressurized air supply source and an insert fits that over a fluid channel in the canister to create a venturi effect and draw the fluid out. The pressurized air supply source creates a clinically effective airflow despite its small size.
