Abstract
Disclosed is a method of providing oxygen rich gas. Oxygen is separated from ambient air with an oxygen separator in discrete pulses, one pulse at a time. The start of the pulse is synchronized with the beginning of an inhalation of a person. The oxygen rich gas in each pulse is separated from the ambient air in real time during a nitrogen adsorption step concurrent with each inhalation.
Claims12
A delivery system for oxygen separated from ambient air comprising:
- a separator comprising:
- at least one separation column, the separation column containing an inlet at a first end and an outlet at a second end;
- a buffer column having a single inlet at a first end;
- a vacuum pump;
- a valve system that connects the vacuum pump with the separation column;
- a nose cannula;
- wherein the oxygen separator is capable of separating oxygen from air in discrete pulses in response to inhalation by a person through the nose cannula.

A delivery system for oxygen separated from ambient air comprising:
- a separator comprising:
- at least one separation column, the separation column containing a first port at a first end and a second port at a second end;
- a buffer column having a third port at a first end;
- a vacuum pump;
- and
- a valve system that connects the vacuum pump with the separation column, and connects the separation column and buffer column;
- and
- a cannula;
- wherein the oxygen separator is capable of separating oxygen from air in discrete pulses in response to inhalation by a person through the cannula;
- and
- wherein the oxygen separator utilizes the buffer column containing the third port at the first end thereof for controlling flow in and out of the buffer column, functioning as a last in/first out (LIFO) buffer for the purity of a separated gas flowing in and out of the separation column.
