Respiratory Medicament Nebulizer System

摘要

A nebulizer system includes a body having a fluid chamber and an aerosol chamber, and a vibrator assembly positioned at an interface between the fluid chamber and the aerosol chamber. The vibrator assembly may include a diaphragm, having a fluid side and an aerosol side, defining a plurality of perforations between the fluid side and the aerosol side, and one or more vibrator elements operatively associated with the diaphragm to vibrate the diaphragm to produce aerosolized medicament projected into the aerosol chamber from the plurality of perforations. Each perforation of the plurality of perforations projects the aerosolized medicament along a respective projection path relative to a plane defined by the aerosol side of the perforation, the one or more vibrator elements or the diaphragm support substrate further being configured to angularly displace the aerosol side of the diaphragm to sweep the direction of at least one projection path.

1. A nebulizer system comprising:
a body having a fluid chamber and an aerosol chamber; a vibrator assembly, positioned at an interface between the fluid chamber and the aerosol chamber, the vibrator assembly comprising: a diaphragm having a diaphragm support substrate operatively associated therewith, the diaphragm having a fluid side in fluid communication with the fluid chamber and an aerosol side in communication with the aerosol chamber, the diaphragm defining a plurality of perforations between the fluid side and the aerosol side; and one or more vibrator elements operatively associated with the diaphragm to vibrate the diaphragm to project aerosolized medicament into the aerosol chamber from the plurality of perforations; wherein each perforation of the plurality of perforations project the aerosolized medicament along a respective projection path relative to a plane defined by the aerosol side of the perforation, the one or more vibrator elements or the diaphragm support substrate further being configured to angularly displace the aerosol side of the diaphragm to sweep the direction of at least one projection path.
