A hand-held nebulizer system is provided which nebulizes during the patient's inspiration cycle only. The system includes a universal sensor port adapter which is adapted to fluidly connect an airway device with a sensor port of the system's source of pressurized gas in such a manner as to permit the patient to inhale and exhale atmospheric air, while permitting the use of standard airway devices. A unique valve arrangement is also provided in the device for supplying the pressurized gas which permits the system to be extremely sensitive to small pressure differentials, thereby ensuring that the system detects the respiratory cycle phases of even the weakest patients.

[ What is claimed is:] [1.] An adapter device for use in an apparatus for delivering pressurized gas to a patient during inhalation and for preventing delivery of pressurized gas to the patient during exhalation, said adapter device being adapted to couple an airway device to a sensor port associated with a pressurized gas supply source, and comprising:a generally tubular element having a fluid passage extending therethrough, and having a connector end adapted for insertion into an expired gas outlet port in such an airway device, and a sensor end adapted to be coupled to a proximal end of a fluid line, such a fluid line being adapted to be coupled at a distal end thereof with such a sensor port; andstructure for ensuring that such an expired gas outlet port remains open to atmosphere when said connector end is inserted therein, said structure comprising a generally disk-shaped element circumscribing said tubular element between said sensor end and said connector end, the disk-shaped element having at least one hole extending therethrough, a connector end of said hole being disposed in an axially spaced relationship relative to said tubular element connector end, such that a substantial portion of said tubular element connector end may be inserted into an expired gas outlet port in order that said connector end of said hole abuts the expired gas outlet port, and the airway device is open to atmosphere through said at least one hole.
