Abstract: A electrohydrodynamic aerosol sprayer wherein a gas flow deflector is used for creating a gas flow past the spray nozzle to stabilize the Taylor cone and to transport at least a portion of the aerosol away from the region downstream of the spray nozzle. This stabilization of the cone and transport of aerosol improves the droplet size and distribution and may also reduce the deposit of droplets on the internal components of the device.

Abstract: A device and method for delivering an aerosolized liquid having therapeutic properties to a user's lungs. The compact and convenient device includes a housing of such size that it can be held in a user's one hand with an exit opening in the housing for directing the aerosol to the user's mouth. The housing encloses a dispensing system for containing the liquid to be aerosolized and delivering it to an electrohydrodynamic apparatus and an electrohydrodynamic apparatus for aerosolizing the liquid and delivering the aerosol to the exit opening. The electrohydrodynamic apparatus produces a cloud of aerosolized liquid droplets having a monodispersed respirable droplet size and near zero velocity. The aerosolizing apparatus includes a plurality of spray sites each having a tip end, the spray sites cooperating with a charge source to result in an aerosolized spray from at least one tip end, a plurality of discharge electrodes downstream of the tip ends, and a plurality of reference electrodes downstream of the plurality of discharge electrodes.

Abstract: An improved Electrohydrodynamic (EHD) nozzle particularly suitable for a handheld pulmonary aerosol inhaler increases the consistent and efficient dispensing of therapeutic liquids by reducing or eliminating wetting through shielding of discharge electrodes. Some versions further eliminate wetting while enhances neutralization of the aerosol through presentation of a corona wind of ions annularly surround the aerosol. Incorporation of improved liquid distribution with consistent pressure drops to each EHD nozzle tip allows horizontal dispensing, and by using dielectric nozzle tips with low surface energy to thereby avoid wicking between dispenses and to advantageously reduce achievable particle size when dispensing. Some versions feature enhanced snap-fit assembly and other manufacturability advantages. One of the unique features of the EHD nozzles is achieved high dose rate (microliters/minute) with low wetting and small particle size (1.0-5 microns), although these properties tend to be mutually exclusive. Furthermore, these attributes are incorporated into a conveniently small, handheld device.
