Face masks for use in a pressurized system of drug supply and method to reduce deposition of aerosolized drug in ocular regions of a patient wearing a face mask

摘要

"Facial masks for use in a pressurized system of drug supply and method to reduce deposition of aerosolized drug in ocular regions of a patient using a facial mask.Face masks (170) for use in applications pressurized supply of drugs, such as aerosol drug supply systems.And a method to reduce aerosol deposition in the region of the eyes are presented.The facial masks according to the various configurations disclosed here contain features (150) which reduce the inertia of the aerosolized drug in areas perinasais.This results in a reduction in the amount of aerosolized drug is deposited in the region of the eyes by inertial impact, while at the same time,The characteristics (150) are constructed to maintain the flow of aerosolized drug into the face mask such that the aerosolized drug is effectively delivered to the respiratory systemThe patient.
