Abstract
Hypoxic delivery apparatus producing from ambient air a product gas having a lower levels of oxygen concentration and delivering the product gas to a user of the apparatus in pulse doses. Alternatively, the apparatus may include a selector for alternately delivering either a nitrogen enriched gas or an oxygen enriched gas to the user.
Claims14
A compact and portable hypoxic gas delivery apparatus by producing from ambient air a product gas having lower levels of oxygen concentration and delivering the product gas to a user of the apparatus, the apparatus comprising a pressure swing adsorption unit having at least one adsorber bed to receive ambient air and adsorb the nitrogen or the oxygen from the ambient air to produce both a nitrogen enriched gas and an oxygen enriched gas, and control means for delivering the nitrogen enriched gas in a pulse dose to a user for a selectable predetermined period of time and actuated upon initial inhalation by the user, the control means further comprising means for increasing or decreasing the effective flow rate of the nitrogen enriched gas by increasing or decreasing the activation time during each inhalation cycle.
