Abstract:

An improved nebulizer is provided which includes a hollow generally elongated housing defining a central chamber containing a body of nebulizable liquid. The housing has a gas entry port adjacent its lower end and a nebulized liquid exit port adjacent its upper end. A gas conduit having a central passageway is connected to and extends below the gas entry port and includes a branch which extends laterally thereof and defines a gas relief port. The relief port may have a removable cap and is used to control the flow of gas into the chamber (by means of blocking the relief port or leaving the relief port open). Thus, fingertip control of the flow of nebulized liquid from the nebulizer is provided. An elongated nozzle assembly is connected to the gas entry port and extends up in the chamber. The assembly includes an inner gas-containing tube connected to the gas conduit and an outer annular liquid-containing tube having access to the body of nebulizable liquid.
