| 128201210 | Using liquified oxygen | 8 |
| 20080202508 | Oxygen concentrator system - An oxygen concentrator system includes a portable system having a portable oxygen concentrator with a portable compressor. The portable system further includes a power supply, a control system, and a portable oxygen outlet configured to selectively provide a first direct fluid supply. A station is configured to engage the portable system. The station may be selectively controlled by the control system when engaged with the portable system. The station may have a stationary oxygen concentrator that is inoperable for delivering a second direct fluid supply via a stationary oxygen outlet during delivery of the first direct fluid supply via the portable oxygen outlet when the station and portable system are engaged. Further, the portable oxygen concentrator is inoperable for delivering the first direct fluid supply via the portable oxygen outlet during delivery of the second direct fluid supply via the stationary oxygen outlet when the station and portable system are engaged. | 08-28-2008 |
| 20100116270 | Medical Ventilator System and Method Using Oxygen Concentrators - A medical ventilator system that allows the use of pulse flow of oxygen to gain higher FIO | 05-13-2010 |
| 20110073107 | CONTROLLING AND COMMUNICATNG WITH RESPIRATORY CARE DEVICES - Disclosed are methods, systems, apparatus, and products, including a method for operating a respiratory care device that includes collecting at a respiratory care device data representative of operation of the respiratory care device, and communicating to a computing-based device external to the respiratory care device at least some of the collected data to control the operability of the respiratory care device. In some embodiments, the method may further include communicating to the respiratory care device data to controllably change one or more operation parameters of the respiratory care device to cause a change in the operation of the respiratory care device, changing the operation parameters of the respiratory care device according to the communicated data, and communicating to the external computing-based device resultant data representative of operation of the respiratory care device resulting from the controllable change to the one or more operation parameters. | 03-31-2011 |
| 20120000462 | Portable Oxygen Delivery Device - Disclosed are devices, systems, and methods, including an oxygen delivery device that includes an oxygen delivery module to produce at least concentrated oxygen, a gas moving device to deliver air to the oxygen delivery module, at least one motor to controllably drive the gas moving device, an energy source to power at least the at least one motor, a pressure sensor to determine a pressure level, and a purity sensor to determine oxygen purity value. The device also includes a controller to control, based on the oxygen purity value and the pressure level, at least the gas moving device's operations and the oxygen delivery module's operations to cause the pressure resulting from gas moving device to be substantially at a pre-determined pressure value and to cause the purity level of the oxygen produced by the oxygen delivery module to be substantially at a pre-determined purity value. | 01-05-2012 |
| 20120118285 | METHODS, SYSTEMS AND DEVICES USING LOX TO PROVIDE VENTILATORY SUPPORT - A portable liquid oxygen system may provide an average flow rate of oxygen gas at approximately 6-approximately 20 lpm using a rapid gas conversion mode. | 05-17-2012 |
| 20120152240 | Method and Apparatus for Delivering a Dose of a Gaseous Drug to a Patient - A method and device that can vary the dose of a gaseous drug provided to a patient based on a comparison of the normal resting breath rate for each individual patient and the current breath rate of the patient so that the patient does not become desaturated. | 06-21-2012 |
| 20130068220 | SYSTEMS AND METHODS FOR GENERATING LIQUID OXYGEN FOR PORTABLE USE - A system for generating liquid oxygen (LOX) for portable use by a patient includes a patient portable unit configured to store LOX and deliver gaseous oxygen (GOX) to the patient, and a mobile base unit configured to generate LOX by cryogenic separation of air and deliver the generated LOX to the patient portable unit. The mobile base unit includes a compressor that receives and pressurizes air, a purifier that removes impurities from the pressurized air, a heat exchanger that cools the purified air, a cryocooler that further cools the air to cryogenic temperatures, and a distillation unit that separates the cryogenic air into multiple products, including LOX and one or more cold byproducts. The separated LOX is communicated toward storage, and at least one of the cold byproducts is passed through the heat exchanger to facilitate heat transfer from incoming purified air to the at least one cold byproduct in order to cool the purified air. | 03-21-2013 |
| 20130306062 | OXYGEN ADMINISTRATION SYSTEM AND METHOD - Systems and methods are provided that employ both a liquid oxygen source and a gaseous oxygen source. In this way, a seamless switch between these sources is possible and oxygen can be continuously provided during replacement of a depleted oxygen source. To this end, an oxygen delivery system includes a connection box and dispenser along with the liquid oxygen source and the gaseous oxygen source. The connection box has a common conduit and first, second, and third ports fluidly coupled to the common conduit. The liquid oxygen source is fluidly coupled to the common conduit through the first port and the gaseous oxygen source is fluidly coupled to the common conduit through the second port. The dispenser is fluidly coupled to the common conduit through the third port. Such systems and methods provide uninterrupted oxygen to injured persons and can improve the time and/or effectiveness of recovery. | 11-21-2013 |
