Abstract

Systems and methods for evaluating medication delivery from valved holding chambers (VHCs) with a facemask using a model face of a child or a model face of an infant are disclosed. Generally, the model face includes a base, an elastomer cast, an air pocket, and a mouth opening. The elastomer cast is positioned on at least a portion of a top of the base. The elastomer simulates soft tissues in a face and defines at least a nose, a chin, and a mouth sized to simulate a nose, a chin, and a mouth of a child. The air pocket is positioned between the base and the elastomer case below at least the nose, the chin, and the mouth of the elastomer cast. The mouth opening defines a passageway through the base, the air pocket, and the mouth of the elastomer cast.
