Abstract
Apparatus for the inhalation of medicinal agent is disclosed which comprises forming an aerosol, containing the medicinal agent, within a venturi tube-shaped interior configuration. The apparatus comprises a housing for receiving incoming air and combining the same with a medicinal agent passed from a container supported on the housing. The housing has a converging air inlet chamber in communication with an adjacent constriction. The constriction, in turn, communicates with an aerosol delivery section via a diverging diffuser chamber. The diffuser chamber may be part of the housing and the delivery section, which section provides for oral or nasal application may be attached thereto. In the alternative, the diffuser chamber and aerosol delivery section may comprise a single section integrally formed with the housing. The diffuser chamber, constriction and air inlet chamber cooperate to define the venturi tube-shaped configuration. Medicinal agent from the container enters the housing interior proximate the constriction, thoroughly combines with incoming air to form an aerosol, and exhausts through the aerosol delivery section.
