128205110 | Means for varying air/oxygen ratio | 8 |
20090025726 | Hypoxic conditioning in patients with exercise limiting conditions - Patients having exercise limiting conditions and those at risk of developing such conditions are exposed to a regimen of hypoxic conditions that simulate various altitude conditions. The exposure is of a temporary nature, being from a few hours to most of a day or night in any one day and repeated on a personally worked out regimen of from a series of consecutive days to a regular number of “on” and “off” days, to a random number of days. An alternate regimen is such exposure for a few minutes at a time followed by normoxic rest period of a few minutes, with the cycle repeated multiple times over the course of a treatment session. The conditioning treatment strengthens the cardiac tissue and skeletal muscle and the results extend beyond the treatment periods whereby the patient's condition is substantially improved. | 01-29-2009 |
20090308396 | Wearable Oxygen Concentrator System - A wearable oxygen concentrator system is provided. The wearable oxygen concentrator system includes a pumping system configured to receive air and to remove nitrogen gas from the air to obtain concentrated oxygen. The pumping system is further configured to deliver the concentrated oxygen via a cannula tube to a person. The wearable oxygen concentrator system further includes a clothing member configured to be worn by the person. The clothing member is configured to hold the pumping system therein. | 12-17-2009 |
20100258127 | ADAPTABLE DEMAND DILUTION OXYGEN REGULATOR FOR USE IN AIRCRAFTS - A system and method of automatic delivery of appropriate flow rate of oxygen to a person flying in a pressurized aircraft cabin is disclosed.

Embodiments described herein provide methods for oxygen reprocessing of expiratory gases wherein exhaled air is reprocessed using filters and adsorbers and delivered to a patient based on a clinically specified oxygen concentration. Embodiments described herein provide for graphical display of the oxygen concentration of the product gas of oxygen reprocessing. Embodiments described herein also disclose an automated ventilator functionality whereby oxygen concentration may be set by clinicians through a user interface display, or a “Oxygen Reprocessing Input” screen, from a general ventilation input screen. Embodiments described herein also disclose a ventilator system configured to undergo oxygen reprocessing of expiratory gases and to provide the product gas to the patient for inspiration. | 09-01-2011 |
20110247623 | AIR/OXYGEN VENTILATOR SYSTEM AND METHOD - Provided is a portable ventilator system, including a ventilator supply system having a ventilator mask, an air/oxygen source and an air/oxygen regulator system, and including a communications device that, during use, automatically contacts an emergency response entity in response to activation of the portable ventilator system. Also provided is a ventilator system that includes at least one ventilator mask sized to fit upon a selected range of sizes of human faces, a ventilator supply system having an air/oxygen source and an air/oxygen regulator system, and an air/oxygen flow regulation valve having an inlet, an inlet/outlet in communication with a ventilator mask coupled to the ventilator supply system, and an outlet in communication with a surrounding atmosphere. During use, air/oxygen flows through the inlet and the inlet/outlet to facilitate ventilation of a human, and air/oxygen flows through the inlet/outlet and the outlet to facilitate exhalation by a human to the surrounding atmosphere. Further, during use, one of the ventilator masks is coupled to the ventilator supply system to provide air/oxygen to a human, and the air/oxygen regulator system regulates air/oxygen flow parameters as a function of a size of the ventilator mask coupled to the ventilator supply system. | 10-13-2011 |
20120055480 | VENTILATOR SYSTEMS AND METHODS - Described herein are various embodiments of an oxygen concentrator system. In some embodiments, an oxygen concentrator system may be used to provide oxygen enriched gas to a patient undergoing ventilation. | 03-08-2012 |
20120060841 | OXYGEN ENRICHMENT DEVICE FOR VENTILATOR - An enrichment device for mixing ambient air with a gas such as oxygen has a rigid outer housing defining a reservoir. The housing has an outlet port for attachment to a cyclic low pressure source, an ambient air inlet, and a second inlet for connection to a supply of pressurized gas. The reservoir has a plurality of internal walls defining a passageway having a plurality of turns defining a tortuous path for gas flow between the ambient air inlet and the outlet port, and the second inlet communicates with the passageway at a location at or close to the outlet port. | 03-15-2012 |
20130025599 | ADAPTABLE DEMAND DILUTION OXYGEN REGULATOR FOR USE IN AIRCRAFTS - A method of automatic delivery of appropriate flow rate of oxygen to a person flying in a pressurized aircraft cabin is disclosed. In one embodiment, a first aneroid valve that is responsive to differential gas pressure in a first altitude range is preset to close at a oxygen starting altitude point based on apriori lung capacity test. Further, flow of oxygen is initiated from an oxygen bottle using quarter turn switching regulator connected to the oxygen bottle via a minimum flow area of main valve to output a mixture of the flow of oxygen and aircraft cabin air into a mixing chamber. Furthermore, the first aneroid valve is gradually closed in response to increasing aircraft cabin pressure altitude to stop the pilot flow of oxygen during the first altitude range. Then, main valve is opened upon closing the first aneroid valve to flow pressurized oxygen into the mixing chamber. | 01-31-2013 |
