Portable Fluid Delivery System for the Nasal and Paranasal Sinus Cavities

摘要

A portable nasal irrigator houses an airflow regulating system, instead of external bulky, heavy components, to power and automate the atomization of fluid for irrigation of nasal passages or for the delivery of drugs. The airflow regulating system is made up of a pump, a motor to drive the pump, a filter for filtering air, and a programmable circuit board to control the motor and regulate and maintain a power supply. The airflow regulating system is configured, via the programmable circuit board, to limit a number of actuations performed by the airflow regulating system over a predetermined dispensing period. Alternatively, the airflow regulating system is configured to limit a run time for each actuation of the airflow regulation system.
