Abstract
Abstract Apparatus for administering nebulized gas to a patient includes a connector having a tubular nozzle communicating with an oxygen supply, a tubular spike portion, and a smaller diameter water supply tube within the spike portion and extending beyond the end of the spike portion for first piercing the stopper in an intravenous solution bottle. The spike portion enlarges the hole pierced by the water supply tube. The oxygen supplied through the nozzle creates a vacuum in the water supply tube, drawing water from the bottle into the oxygen stream. The oxygen and water mixture impinges against a small sphere, nebulizing into a fog of small water droplets within a chamber. A flexible tube connected to the chamber delivers the nebulized fog to the patient. A rotatable valve structure controls the entrance of ambient air to enter the nebulizing chamber. By rotating one of the valve elements different concentrations of nebulized oxygen can be administered to the patient.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
250 words
A connector for use in a gas nebulizing system that includes a container with liquid and an opening with a closure therein, said connector comprising a body having first tubular means for connection to a gas supply, second tubular means having an end portion shaped for piercing the container closure, third tubular means for immersion in the liquid of the container, said third tubular means being telescoped within said second tubular means, said second tubular means having a spike of larger external diameter than the external diameter of said second tubular means so as to enlarge the opening formed upon piercing said closure by said end portion, said spike being barbed to prevent accidental withdrawal of the connector from the closure, fourth tubular means having a nebulizing chamber, passage-forming means providing communication between said nebulizing chamber and said first and third tubular means, said passage-forming means including a nozzle and a mixing chamber such that gas from said first tubular means will flow through said nozzle and into said mixing chamber and liquid from said third tubular means will flow into said mixing chamber due to vacuum created by the flowing gas, means in said nebulizing chamber for breaking up the flowing gas and liquid mixture into a mass of droplets, adjustable air valve means providing communication between the exterior of said body and said fourth tubular means for regulating the concentration of said gas in said chamber, and means for carrying rainout liquid from said chamber to said container.
Claim 2
Dependent Claim
250 words
A connector for use in a gas nebulizing system that includes a container with liquid and an opening with a closure therein, said connector comprising a body having first tubular means for connection to a gas supply, second tubular means having an end portion shaped for piercing the container closure, third tubular means for immersion in the liquid of the container, said third tubular means being telescoped within said second tubular means, said second tubular means having a spike of larger external diameter than the external diameter of said second tubular means so as to enlarge the opening formed upon piercing said closure by said end portion, said spike being barbed to prevent accidental withdrawal of the connector from the closure, fourth tubular means having a nebulizing chamber, passage-forming means providing communication between said nebulizing chamber and said first and third tubular means, said passage-forming means including a nozzle and a mixing chamber such that gas from said first tubular means will flow through said nozzle and into said mixing chamber and liquid from said third tubular means will flow into said mixing chamber due to vacuum created by the flowing gas, means in said nebulizing chamber for breaking up the flowing gas and liquid mixture into a mass of droplets, adjustable air valve means providing communication between the exterior of said body and said fourth tubular means for regulating the concentration of said gas in said chamber, and means for carrying rainout liquid from said chamber to said container.
Claim 3
Dependent Claim
26 words
A connector according to claim 1 in which said means for carrying the rainout liquid includes said second tubular means and by-passes said third tubular means.
Claim 4
Dependent Claim
33 words
A connector according to claim 1 in which said means for breaking up the mixture comprises a bulbous member that is spaced from said mixing chamber and against which the flowing mixture impinges.
Claim 5
Dependent Claim
88 words
A connector according to claim 1 in which said adjustable air valve means comprises a flange over an opening in said fourth tubular means, said flange being integral with said first tubular means and having openings over a portion of its area and being imperforate over another portion of its area, said flange and fourth tubuLar means being relatively rotatable whereby the openings and imperforate area of the flange serve to control the amount of the opening in said fourth tubular means that is exposed to ambient air.
Claim 6
Dependent Claim
83 words
A connector according to claim 1 in which said fourth tubular means has a section with an opening offset from said first tubular means, said opening having a disc therein with spaced holes, and a cap over said disc with spaced holes, the cap being rotatable relative to said disc to control the amount of overlap of the holes in the disc and cap and thereby vary the amount of the opening in said fourth tubular means that is exposed to ambient air.
