Abstract
Abstract A medicament dispensing apparatus which includes a first housing and a nozzle of the convergent-divergent type having an inlet and outlet adjacent the opposite ends of a nozzle chamber. A reservoir for liquid medicament is located outside the nozzle chamber adjacent the throat of the nozzle, and a metering and dispensing valve is positioned adjacent the throat for injecting a measured amount of medicament from the reservoir into the nozzle. Upon inhaling at the outlet of the nozzle the medicament injected into the nozzle is drawn into the mouth of the patient. A tablet storage and dispensing device in a second housing is provided adjacent the inlet end of the nozzle and includes a tablet container within said second housing. A container closure member for the tablet container is carried by the first housing, and a resilient member normally urges the container and closure together in air-tight engagement. A resilient member inside the container urges a stack of tablets therein into engagement with the closure. When the container and closure are separated, a tablet actuating arm is movable across the inner face of the closure to remove a tablet therefrom. The tablet actuating arm is included on a movable actuating member which also includes a valve actuating arm for operation of said metering and dispensing valve. The tablet storage and dispensing means may be replaced by an aerosol container for injection of medicament therefrom at the inlet of the nozzle chamber from whence it may be drawn through the nozzle by inhalation of the patient.

Claim 1
Independent Claim
218 words
A dispensing apparatus for dispensing fluid medicament comprising, a nozzle having a converging-diverging chamber with air inlet and outlet portions at opposite ends thereof, air inlet means adjacent the inlet end of the nozzle, means for injecting a measured dose of fluid medicament into the nozzle chamber, the fluid medicament injected into the nozzle chamber being drawn into the patient inhaling air through the nozzle, a reservoir for fluid medicament outside the nozzle chamber, said means for injecting a measured dose of fluid medicament into the nozzle chamber including a measuring and dispensing valve, means for manually actuating the valve for injecting a measured dose of fluid medicament into the nozzle chamber from said reservoir, said measuring and dispensing valve including a cylinder having side and end walls formed with a port in the side wall opening into the reservoir of fluid medicament and a self-sealing aperture in the end wall communicating with the nozzle chamber, a member sealing with and reciprocably movable within said cylinder and movable by said means for manually actuating the valve, and means for closing the port in the cylinder side wall and opening the self-sealing aperture in the cylinder end-wall when the reciprocably movable member is actuated by said valve actuating means for transfering fluid from the cylinder into the nozzle chamber.
