Abstract

Abstract A portable reservoir container storing liquid, mounts on its inflow port section a heater and a vortex mixing device in series. Liquid from the bottom of the container is fed to the vortex mixing device in response to the inflow of oxygen gas thereto producing an outflow of liquid and oxygen gas in a vortical flow pattern that is delivered to the inflow port section of the container. A flow of conditioned oxygen gas is discharged from the gas space of the container through an outflow portion section.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 289 words
In combination with a liquid storing container having an inflow port, an outflow port and a liquid feed port, a nebulizer system including a source of oxygen gas under pressure, vortex mixing means connected to said source and said liquid feed port for mixing the oxygen gas and the liquid to produce a vortical flow stream of a mixture of the liquid and the oxygen, means interconnected between the vortex mixing means and the inflow port of the container for conducting said vortical flow stream into the container through said inflow port producing an outflow of conditioned oxygen from the outflow port, and heating means mounted on the container in heat exchange relation to the conducting means for heating the mixture in the vortical flow stream, said heating means and the vortex mixing means being connected in series between the source and the inflow port, wherein said vortex mixing means includes a housing having upper and lower axial ends enclosing a receiving chamber therebetween, an end wall connected to the housing closing said upper axial end, means connected to the source for introducing the oxygen gas to the receiving chamber adjacent said upper end wall, conduit means connected to the liquid feed port and extending through the receiving chamber from said upper end wall for discharge of the liquid from said lower axial end of the receiving chamber, flow restricting wall means connected to said housing at said lower axial end in radially spaced relation to the conduit means for directing restricted discharge of the oxygen gas into the liquid being discharged while the liquid is inside said conduit means, and an annular space extending from said chamber through said lower axial end to produce said vortical stream flow.
Claim 2
Dependent Claim 289 words
In combination with a liquid storing container having an inflow port, an outflow port and a liquid feed port, a nebulizer system including a source of oxygen gas under pressure, vortex mixing means connected to said source and said liquid feed port for mixing the oxygen gas and the liquid to produce a vortical flow stream of a mixture of the liquid and the oxygen, means interconnected between the vortex mixing means and the inflow port of the container for conducting said vortical flow stream into the container through said inflow port producing an outflow of conditioned oxygen from the outflow port, and heating means mounted on the container in heat exchange relation to the conducting means for heating the mixture in the vortical flow stream, said heating means and the vortex mixing means being connected in series between the source and the inflow port, wherein said vortex mixing means includes a housing having upper and lower axial ends enclosing a receiving chamber therebetween, an end wall connected to the housing closing said upper axial end, means connected to the source for introducing the oxygen gas to the receiving chamber adjacent said upper end wall, conduit means connected to the liquid feed port and extending through the receiving chamber from said upper end wall for discharge of the liquid from said lower axial end of the receiving chamber, flow restricting wall means connected to said housing at said lower axial end in radially spaced relation to the conduit means for directing restricted discharge of the oxygen gas into the liquid being discharged while the liquid is inside said conduit means, and an annular space extending from said chamber through said lower axial end to produce said vortical stream flow.
