1. An oxygen concentrator apparatus comprising:
- at least one canister;
gas separation adsorbent disposed in at least one canister, wherein the gas separation adsorbent separates at least some nitrogen from air in the canister to produce oxygen enriched gas; and
a compression system, the compression system comprising at least one compressor coupled to the at least one canister, the compressor comprising;
a first rotor comprising at least two projections;
a second rotor comprising at least two recesses; and
wherein, during rotation of the first and second rotors, gas is moved through the compressor to at least one of the canisters.

Abstract
Oxygen concentrator apparatus and method of use are described herein. The oxygen concentration may include at least one canister; gas separation adsorbent disposed in at least one canister, and a compression system. The compression system may include at least one compressor coupled to the at least one canister. The compressor may include a first rotor comprising at least two projections and a second rotor comprising at least two recesses. During rotation of the first and second rotors, gas moves through the compressor to at least one of the canisters. In the canisters, gas separation adsorbent may separate at least some nitrogen from air produce oxygen enriched gas.

12. A method providing oxygen enriched gas to a user of an oxygen concentrator, the oxygen concentrator comprising:
-
at least one canister; and gas separation adsorbent disposed in at least one canister, a compression system, the compression system comprising at least one compressor coupled to at least one canister, at least one compressor comprising; a first rotor comprising at least two projections; a second rotor comprising at least two recesses; and a drive transmission system coupled to the first and second rotors; the method comprising; applying power to the drive transmission system such that the drive transmission system rotates the first and second rotors in opposite directions, wherein rotation of the first and second rotors draws air into the compression system and discharges air to at least one canister; and separating at least some nitrogen from air in the canister to produce oxygen enriched gas. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
