Abstract
Provided is an oxygen concentration device that can facilitate easy and secure replacement work, such as attaching and detaching the adsorption cylinder while reducing the force applied from the oxygen concentration device body to the adsorption cylinder cartridge in the direction of detaching and thus ensuring the connection with the oxygen concentration device, wherein the axis line of the gas flow direction of the adsorption cylinder intersects with either connection axis in the end part for supplying pressurized air to the adsorption cylinder or the end part for extracting oxygen from the adsorption cylinder.
