A pressure swing adsorption apparatus for producing a gas mixture with a higher concentration of a particular gas such as oxygen from ambient air, in which the noisier components of the apparatus are contained in an internal removable module that is separated by sound insulation from the balance of the apparatus to attenuate structure borne vibration, reduce radiated noise, and to absorb airborne sound.

Reduced noise oxygen concentrator

A combination flow regulator and conservation device, for oxygen gas or oxygen concentrated gas, attachable to an oxygen tank or wall outlet of a master oxygen system and containing a gas regulator and a control circuit to control both the effective rate and timing of the flow of gas through the device, the control circuit selectively controlling the device to supply the gas to a user in one of at least three selectable modes of operation, the modes including (1) a continuous flow of gas, (2) an intermittent pulse of gas to be supplied on every inhalation stage of the breathing cycle of the user for a variable period of time during the inhalation stage, and (3) an intermittent pulse of gas to be supplied only during selectable inhalation stages of the breathing cycles of the user.

Combined oxygen regulator and conservation device

A ball type flowmeter having an external transparent housing on which a flow rate scale is pre-printed, and contained in the housing is a transparent tube having a floating ball, the tube being slidable in the housing and having upper and lower flanges to be moved into and then fixed at a position at which the ball indicates the flow rate of a test gas.
