Abstract
Abstract A humidifier for humidifying gas with a liquid has a cavity defined by top, bottom, and side walls. An interior wall is attached to the side wall and defines a first and second cavity within the enclosed cavity. At least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall extend through the interior wall to provide fluid flow communication between the first and second cavities. An enclosed conduit for the introduction of a gas to be humidified is secured to the side wall. The enclosed conduit has a closed end and an opening adjacent the closed end, which opening extends through the side wall of the humidifier adjacent the bottom wall and opens into the first cavity. The opening through the side wall provides for the formation of bubbles of a gas which are introduced into the humidifier through the enclosed conduit. An opening is provided through the top wall of the humidifier for exhausting the humidified gas from the humidifier. A tubular projection extends from the top wall and is in communication with the opening therethrough to provide for exhausting of the humidified gas.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
149 words
A humidifier container comprising: a side wall, top wall, bottom wall, and interior wall defining a first and second chamber within the container between the interior wall and side wall wherein the first chamber comprises a volume which maintains a substantially constant volume of liquid therein when gas is bubbled through such first chamber, and having at least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall, which openings extend through the interior wall connecting the first and second chambers; an enclosed conduit closed at one end fastened to the container and including an opening adjacent the closed end extending through the side wall and into the first chamber of the container; and a tubular projection extending outwardly from the top wall and in communication with the second chamber through an opening extending through the top wall into the second chamber.
Claim 2
Dependent Claim
149 words
A humidifier container comprising: a side wall, top wall, bottom wall, and interior wall defining a first and second chamber within the container between the interior wall and side wall wherein the first chamber comprises a volume which maintains a substantially constant volume of liquid therein when gas is bubbled through such first chamber, and having at least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall, which openings extend through the interior wall connecting the first and second chambers; an enclosed conduit closed at one end fastened to the container and including an opening adjacent the closed end extending through the side wall and into the first chamber of the container; and a tubular projection extending outwardly from the top wall and in communication with the second chamber through an opening extending through the top wall into the second chamber.
Claim 3
Dependent Claim
32 words
A humidifier container as recited in claim 1 wherein such first opening extending through the interior wall is positioned closer to the bottom wall than the opening extending through the side wall.
Claim 4
Dependent Claim
20 words
The humidifier container as recited in claim 1 wherein the opening extending through the side wall has a serrated edge.
Claim 5
Dependent Claim
17 words
A humidifier container as recited in claim 1 further comprising a perforated disk within the enclosed conduit.
Claim 6
Dependent Claim
17 words
A humidifier container as recited in claim 1 further comprising a serrated constriction within the enclosed conduit.
Claim 7
Dependent Claim
17 words
A humidifier container as recited in claim 1 wherein the enclosed conduit is closed at both ends.
Claim 8
Dependent Claim
21 words
A humidifier container as recited in claim 1 wherein the first chamber is substantially lesser in volume than the second chamber.
Claim 9
Dependent Claim
37 words
A humidifier container as recited in claim 1 further comprising an adapter for connecting the humidifier container with a gas supply, which adapter comprises a cap and means on such cap for connection to a gas source.
Claim 10
Dependent Claim
189 words
A humidifier for humidifying a gas with a liquid, the humidifier comprising: an enclosed cavity defined by top, bottom and side walls; a liquid within the enclosed cavity; an interior wall attached to the side wall and defining a first and second cavity within the enclosed cavity wherein the first cavity has a volume sufficient for maintaining the liquid at about a constant volume in such first cavity, and having at least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall, which openings extend through the interior wall to provide fluid flow communication between the first and second cavities; an enclosed conduit for the introduction to the humidifier of a gas to be humidified, secured to the side wall, having a closed end and including an opening extending through the side wall adjacent the bottom wall into the first cavity; means within the enclosed conduit for initiating bubbling of the introduced gas; means within the humidifier for directing the gas bubbles into the first cavity; and means connected to the second chamber for exhausting a humidified gas from the second chamber.
Claim 11
Dependent Claim
189 words
A humidifier for humidifying a gas with a liquid, the humidifier comprising: an enclosed cavity defined by top, bottom and side walls; a liquid within the enclosed cavity; an interior wall attached to the side wall and defining a first and second cavity within the enclosed cavity wherein the first cavity has a volume sufficient for maintaining the liquid at about a constant volume in such first cavity, and having at least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall, which openings extend through the interior wall to provide fluid flow communication between the first and second cavities; an enclosed conduit for the introduction to the humidifier of a gas to be humidified, secured to the side wall, having a closed end and including an opening extending through the side wall adjacent the bottom wall into the first cavity; means within the enclosed conduit for initiating bubbling of the introduced gas; means within the humidifier for directing the gas bubbles into the first cavity; and means connected to the second chamber for exhausting a humidified gas from the second chamber.
Claim 12
Dependent Claim
45 words
A humidifier as recited in claim 9 wherein the means for directing the gas bubbles into the first cavity comprises an opening extending through the side wall further from the bottom wall than the first opening extending through the interior wall adjacent the bottom wall.
Claim 13
Dependent Claim
39 words
A humidifier as recited in claim 9 wherein the means for initiating bubbling of the introduced gas comprises constrictions within the opening extending from the enclosed conduit into the first cavity through the side wall adjacent the bottom wall.
Claim 14
Dependent Claim
20 words
A humidifier as recited in claim 11 wherein the constrictions in the opening comprise a serrated edge on the opening.
Claim 15
Dependent Claim
191 words
A humidifier for humidifying a gas with a liquid, the humidifier comprising: an enclosed cavity defined by top, bottom and side walls; an interior wall attached to the side wall and defining a first and second cavity within the enclosed cavity wherein the first cavity has a volume sufficient for maintaining a liquid present in the humidifier at about a constant volume in such first cavity, the interior wall having at least a first opening adjacent the bottom wall and at least a second opening adjacent the top wall, which openings extend through the interior wall to provide fluid flow communication between the first and second cavities; an enclosed conduit for the introduction to the humidifier of a gas to be humidified, secured to the side wall, having a closed end and including an opening having a serrated edge, which opening extends through the side wall into the first cavity and which opening is spaced further from the bottom wall than the first opening extending through the interior wall; and an outlet in fluid flow communication with the second chamber for providing release of a humidified gas from the second chamber.
