Abstract
Abstract A water supply is adapted as a source for nebulized liquid through the agency of an adapter which couples oxygen pressure to a container for the water. A venturi within the adapter draws from the water supply and directs atomized water and oxygen through an outlet pipe on the adapter. A perforated plate is disposed in the path of flow downstream of the venturi and divides the outlet pipe into inner and outer chambers. It traps water particles which are too large to pass through the plate perforations and passes the remainder. Water which collects upstream of and against the perforated plate in the inner chamber drains into the outer chamber through lowermost perforations. A baffle plate is disposed in the outlet end portion of the outlet pipe; and it intercepts water condensed in the outer chamber and has an arcuate upper opening for passage of nebulized water from the fitting. A duct which is fluidally connected to the outer chamber returns condensed water therefrom to the container and stabilizes pressure therein by providing gas replacement for water removed from the system.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
103 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: said chamber means having a first chamber disposed downstream of said venturi; said chamber means having a second chamber disposed downstream of said first chamber; an element disposed with one of said first and said second chambers for intercepting fluid upstream of said second chamber and having perforations for passing a mist and intercepted fluid from said first chamber to said second chamber and meanS for removing fluid collected in said second chamber from said body.
Claim 2
Dependent Claim
103 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: said chamber means having a first chamber disposed downstream of said venturi; said chamber means having a second chamber disposed downstream of said first chamber; an element disposed with one of said first and said second chambers for intercepting fluid upstream of said second chamber and having perforations for passing a mist and intercepted fluid from said first chamber to said second chamber and meanS for removing fluid collected in said second chamber from said body.
Claim 3
Dependent Claim
122 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: means for removing fluid collected in said chamber means from said body; said chamber means having a first chamber disposed downstream of said venturi; said chamber means having a second chamber disposed downstream of said first chamber; an element disposed with one of said first and said second chambers for intercepting fluid upstream of said second chamber and having perforations for passing a mist and intercepted fluid from said first chamber to said second chamber; and baffle means for preventing a portion of the fluid in said second chamber from passing through said outlet opening.
Claim 4
Dependent Claim
122 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: means for removing fluid collected in said chamber means from said body; said chamber means having a first chamber disposed downstream of said venturi; said chamber means having a second chamber disposed downstream of said first chamber; an element disposed with one of said first and said second chambers for intercepting fluid upstream of said second chamber and having perforations for passing a mist and intercepted fluid from said first chamber to said second chamber; and baffle means for preventing a portion of the fluid in said second chamber from passing through said outlet opening.
Claim 5
Dependent Claim
164 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: means for removing fluid collected in said chamber means in a stream from said body; said chamber means having a delivery pipe disposed in mist receiving association with said venturi; said removing means having a wall section of said pipe with a channel for draining said chamber means and a drain opening through said wall fluidally connected to said channel; said first and said second chambers disposed in coaxial alignment in said pipe; the first chamber disposed in mist receiving association with said venturi; the second chamber having said outlet opening and being adapted to drain said first chamber; an inner baffle arranged medially of said chamber means and for intercepting fluid movement between said first and said second chambers, said inner baffle being perforated for enabling passage of mist and flow of fluid between said chambers.
Claim 6
Dependent Claim
164 words
In a nebulizer wherein the mist forming means comprises a venturi disposed within a body having chamber means with a mist outlet opening, an improvement characterized by: means for removing fluid collected in said chamber means in a stream from said body; said chamber means having a delivery pipe disposed in mist receiving association with said venturi; said removing means having a wall section of said pipe with a channel for draining said chamber means and a drain opening through said wall fluidally connected to said channel; said first and said second chambers disposed in coaxial alignment in said pipe; the first chamber disposed in mist receiving association with said venturi; the second chamber having said outlet opening and being adapted to drain said first chamber; an inner baffle arranged medially of said chamber means and for intercepting fluid movement between said first and said second chambers, said inner baffle being perforated for enabling passage of mist and flow of fluid between said chambers.
Claim 7
Dependent Claim
