Face masks (170) for use in pressurized drug delivery applications, such as aerosol drug delivery systems, and a method of reducing aerosol deposition in the region of the eyes are presented. The face masks according to the various embodiments disclosed herein contain features (150) that reduce the inertia of the aerosolized drug in perinasal ares. This results in a reduction in the amount of aerosolized that is deposited in the region of the eyes by inertial impaction, while at the same time, the features (150) are constructed to maintain the flow of the aerosolized drug into the face mask so that the aerosolized drug is effectively delivered to the respiratory system of the patient.
L'invention concerne des masques faciaux (170) destinés aux applications de distribution de médicaments sous pression, telles que les systèmes de distribution de médicaments en aérosol, ainsi qu'un procédé de réduction des dépôts autour des yeux. Selon divers modes de réalisation, les masques faciaux de l'invention comportent des caractéristiques (150) qui réduisent l'inertie de l'aérosol médicamenteux dans la région périnasale. Ceci a pour conséquence de réduire la quantité d'aérosol déposée autour des yeux par impaction inertielle ; ces caractéristiques (150) étant également conçues pour maintenir le débit du médicament en aérosol dans le masque facial et permettre par conséquent l'administration efficace du médicament en aérosol dans le système respiratoire du patient.
