Abstract
Abstract An apparatus for supplying gas at a reduced pressure from a pressure vessel containing a gas under pressure and having an outlet valve fitted thereon has a plurality of nozzle means. A plurality of stacked spaced-apart chamber means communicates with, and is disposed so as to be alternately supported between the plurality of nozzle means. One of the nozzle means is an inlet nozzle communicating with the gas under pressure. Another of the nozzle means is an outlet nozzle communicating with the outlet valve to thereby provide an expansion path for the gas. Additionally, the apparatus includes a receiving tube disposed about the stacked array of alternately placed nozzle means and chamber means with one end of the receiving tube threadably engaging the outlet valve.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
135 words
A medical (An) apparatus for supplying gas at a reduced pressure from (a) an oxygen bottle pressure vessel containing a pressureized gas and having an outlet valve fitted thereon comprising: an oxygen bottle; a plurality of nozzle means arranged in said oxygen bottle; and a plurality of stacked spaced-apart chamber means communicating with and disposed so as to be alternately supported between said plurality of nozzle means, one of said plurality of nozzle means being an inlet nozzle communicating with the gas under pressure in said oxygen bottle and another of said plurality of nozzle means being an outlet nozzle communicating with (the) said outlet valve to thereby provide an expansion path for the gas from the inlet to the outlet nozzle as it proceeds alternately through said plurality of nozzle means and chamber means.
Claim 2
Dependent Claim
135 words
A medical (An) apparatus for supplying gas at a reduced pressure from (a) an oxygen bottle pressure vessel containing a pressureized gas and having an outlet valve fitted thereon comprising: an oxygen bottle; a plurality of nozzle means arranged in said oxygen bottle; and a plurality of stacked spaced-apart chamber means communicating with and disposed so as to be alternately supported between said plurality of nozzle means, one of said plurality of nozzle means being an inlet nozzle communicating with the gas under pressure in said oxygen bottle and another of said plurality of nozzle means being an outlet nozzle communicating with (the) said outlet valve to thereby provide an expansion path for the gas from the inlet to the outlet nozzle as it proceeds alternately through said plurality of nozzle means and chamber means.
Claim 3
Dependent Claim
29 words
The apparatus as in claim 1 wherein at least one of said plurality of chamber means is a substantially pear-shaped chamber having a largest diameter of approximately 11 mm.
Claim 4
Dependent Claim
23 words
The apparatus as in claim 2 wherein said pear-shaped chamber is located at the beginning of the expansion path adjacent the inlet nozzle.
Claim 5
Dependent Claim
27 words
The apparatus as in claim 1 wherein at least one of said plurality chamber means is a substantially spherical chamber having a diameter of approximately 11 mm.
Claim 6
Dependent Claim
23 words
The apparatus as in claim 4 wherein said spherical chamber is located at the end of the expansion path adjacent the outlet nozzle.
Claim 7
Dependent Claim
45 words
The apparatus as in claim 1 in which each of said plurality of nozzle means has an inside diameter equal to or less than the next adjacent one of said plurality of nozzle means in the direction from the inlet nozzle to the outlet nozzle.
Claim 8
Dependent Claim
58 words
The apparatus as in claim 1 wherein said chamber means comprises four chambers, and wherein said nozzle means comprises five nozzles, three of said nozzles communicating between adjacent ones of said chambers, and wherein another of said nozzles forms the inlet nozzle and the fifth one of said nozzles forms the outlet nozzle communicating with the outlet valve.
Claim 9
Dependent Claim
33 words
