FACE MASK APPLIED IN SYSTEMS OF DRUG ADMINISTRATION UNDER PRESSURE Russian patent published in 2009 - IPC A61M16/06 A62B18/02 

FIELD: medical equipment.

SUBSTANCE: invention is intended for application in drug administration under pressure, e.g. in aerosol drug administration system. In one version, face mask includes at least partially deformed case with surface contacting patient's face, nose bridge zone made in the upper case part, lower bent section where part of case is bent for positioning over face, and two holes in eye area at different sides of nose bridge. When the mask is placed over patient's face, the holes can be positioned over patient's eyes. Case is shaped so as the lower bent part is at least partially creased when mask is placed over face, and eye holes can form gap remaining open between internal edge of the hole and face part below eyes to provide outlet for mask placed over face with at least partial crease of lower bent section.

EFFECT: facial masks in different implementation version reduce aerosol particle inertia in areas close to nose, thus reducing amount of aerosol drug precipitation in eye area in the result of inertial sedimentation impact, while aerosol drug flow in mask cavity is maintained at level required for efficient drug supply to respiratory system of patient.
