  • Publication number: 20150101603
    Abstract: Lightweight, portable oxygen concentrators that operate using an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices.

  • Publication number: 20150083121
    Abstract: A portable life support apparatus (1102) and particularly a respiratory support apparatus adapted to be easily mounted to a stretcher is disclosed. Prior devices that attach onto a stretcher are heavy and cumbersome and obstruct access to the patient. Accordingly, there is a great need for a portable emergency support device that overcomes the weight, size, positioning, and other portability disadvantages. One aspect relates to a portable life support device including at least one ambient gas inlet (14); a conditioned gas outlet (30); an oxygen concentrator (26,28) fluidly connected between the at least one gas inlet and the gas outlet, and a ventilator (44) fluidly connected downstream from the oxygen concentrator.

  • Publication number: 20150068518
    Abstract: A method of producing breathing air includes receiving intake air from an ambient air source, collecting the intake air in one or more collection pots of a distribution system, and distributing the intake air from the one or more collection pots to one or more breathing hoses. The method further includes continuously monitoring the intake air communicated to the one or more collection pots for one or more parameters and periodically recording readings of the continuous monitoring communicated wirelessly in the distributed system.

  • Publication number: 20150059742
    Abstract: An oxygen concentrator may rely on a pressure swing adsorption process to produce an oxygen enriched gas stream from canisters filled with granules capable of separation of oxygen from an air stream. The adsorption process uses a cyclical pressurization and venting of the canisters to generate an oxygen enriched gas stream. The oxygen concentrator system may include one or more flow restrictors to allow controlled release of oxygen enriched gas between the canisters.

  • Patent number: 8944049
    Abstract: Various systems and devices for generating nitric oxide are disclosed herein. According to one embodiment, the device includes a body having an inlet, an outlet, and a porous solid matrix positioned with the body. The porous solid matrix is coated with an aqueous solution of an antioxidant, wherein the inlet is configured to receive a gas flow and fluidly communicate the gas flow to the outlet through the solid matrix to convert nitrogen dioxide in the gas flow into nitric oxide. The porous solid matrix allows the device to be used in any orientation. Additionally, the porous solid matrix provides a rigid structure suitable to withstand vibrations and abuse without compromising device functionality.

  • Publication number: 20140345610
    Abstract: A respiration system is provided with a container (1) in which, by an exothermic chemical reaction of a reaction material, CO2 is removed from the respiration air or oxygen is generated, and with an indicator of the consumption of the reaction material. The consumption indicator has a predetermined amount (7) of material which can be melted by the reaction heat of the exothermic chemical reaction. The material is kept in thermal contact with the container interior in such a manner that a measurement of the total reaction heat, and thus the consumption of reactive material, can be read from the degree of melting of the meltable material.
