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.

主权项

1. A portable nasal irrigator to deliver drugs to the nose or to wash out the nasal cavity, comprising:
(a) a main canister comprising an air exit port, wherein the air exit port extends beyond a rim of the canister; and (b) an insert with a base that fits within the canister; and (c) a pressurized air supply source contiguously attached without tubing to the canister for introducing pressurized air through the air exit port, said pressurized air supply source comprising therein an airflow regulating system comprising: an air outlet, a pump, a motor, a filter for filtering incoming air, external indicators for indicating the status of the portable nasal irrigator and a programmable circuit board to control the motor and to regulate and maintain a power supply; the pump in communication with the main canister and the motor, and the filter connecting to the pump; wherein the airflow regulating system is configured to limit a number of actuations performed by the airflow regulating system over a predetermined dispensing period.
