PATIENT INTERFACE MEMBER FOR USE IN AN AEROSOL INHALATION SYSTEM

摘要

A device for use in an aerosol inhalation system for delivering aerosolized medication includes a means for generating aerosolized medication and a housing that is operatively connected to the means for generating aerosolized medication such that the aerosolized medication is delivered to the housing. The device also includes a patient interface member removably connected to the housing and being separate therefrom. The patient interface member is for placement about a face of the patient and in communication with a mouth of the patient for delivering the aerosolized medication. The patient interface member incorporates a first flow control means that is positionable between an open position where aerosolized medication flows into an interior of the patient interface member when the patient inhales and a closed position when the patient exhales. The exhaled gas is vented from the interior through at least one vent port that is part of the patient interface member.
