  • Patent number: 8915248
    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. During venting of the canisters, use of oxygen as a purge gas may improve the efficiency and lifetime of the oxygen concentrator.

  • Patent number: 8794238
    Abstract: A filtering face-piece respirator 10 that comprises a mask body 12 and a harness 14 that is joined to the mask body 12. The mask body 12 includes a filter layer 30 and a nonwoven fibrous cover web 16. The fibrous cover web 16 is partially occluded and is generally parallel to and spaced from the filter layer 30 such that air passing through the cover web 16 can move freely between the cover web 16 and the filter layer 30 so that it can enter the filter layer 30 at essentially any available point over the filter layer surface 32. The inventive respirator is beneficial in that it can provide very good splash fluid and airborne contaminant protection while also exhibiting an extraordinary low pressure drop across the mask body during breathing.

  • Patent number: 8763610
    Abstract: The processing of gas mixtures, in particular, of respiration gases for ventilated patients. The processing according to the invention relates, in particular, to the use of selective gas separation membranes for the retention of noble gases in the exhaled air of ventilated patients. The gas separation membrane is an active separator which is integrated in a ventilator. The separation membrane separates the noble gases from the remainder of the residual of the exhaled air by selectively retaining the noble gases. Thus, it is possible to provide a ventilator which enables the application of noble gases, in particular xenon, as an anesthetic preferably with low loss and as simple as possible.
