Abstract
Abstract An oxygen-generating device comprising a canister which has oxygen-generating material for reacting with a reacting agent, preferably water, which is placed in a closed pierceable container also disposed in the canister. Means for releasing the reacting agent, preferably a needle, is mounted in the canister for piercing the container to release the reacting agent to the oxygen-generating material. A filter is included to filter the impurities from the oxygen gas before it passes through valved outlet means.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
145 words
An oxygen generator for generating oxygen comprising: a canister having top and bottom ends and a partition wall dividing the upper portion of said canister into first and second side by side chambers and terminating in spaced relation with said bottom end; oxygen-generating material in the bottom end of said canister in both chambers for accomplishing the generation of oxygen gas, when activated; outlet control valve means in communication with said first chamber for controlling the release of oxygen gas; container means including a flexible, pierceable film wall supported by said partition wall for containing an activating agent in said second chamber; and needle means movably mounted on said canister for movement from a removed position to a position piercing the film wall for piercing said film wall and releasing said agent to react with the generating material and produce a flow of oxygen gas.
Claim 2
Dependent Claim
27 words

Claim 9
Dependent Claim
34 words
The oxygen generator set forth in claim 9 including a support ledge in said second chamber, and a rigid support member forming a top for said pierceable plastic film bag supported by said ledge.
Claim 10
Dependent Claim
90 words
A readily portable oxygen generator for the in situ generation of oxygen gas comprising: a canister having outlet control valve means for releasing oxygen gas; an oxygen-generating material for the generation of oxygen in said canister when activated; container means including a flexible film wall, containing a reacting agent proximate said oxygen-generating material but held out of contact therewith; and needle means movably mounted on said canister for piercing said plastic film wall and releasing said agent to react with the generating material and produce a flow of oxygen gas.
