Abstract:
1. A trans-fill system comprising: an initial compressor configured to generate a low pressure gas stream from ambient gas; an oxygen concentrator configured to receive the low pressure gas stream and produce a low pressure oxygen-enriched gas stream; a compression system that receives the low pressure oxygen-enriched gas stream at an inlet, the compression system having a first compression stage that creates an intermediate pressure oxygen-enriched gas stream from the low pressure oxygen-enriched gas stream, and a second compression stage that creates a high pressure oxygen-enriched gas stream from the intermediate pressure oxygen-enriched gas stream; a conserver coupled to the intermediate pressure oxygen-enriched gas stream, the conserver adapted to deliver a bolus of therapeutic gas to a patient during at least a portion of an inhalation cycle of the patient; and a fill port operatively coupled to the high pressure oxygen-enriched gas stream, wherein filling a storage vessel via the fill port is provided substantially simultaneously with providing therapeutic gas via the conserver.
