Abstract: The present invention relates to a gas composition device that can be used for the sterile transport and storage of a gas composition that will be used with regard to a human or an animal. The device of the present invention consist essentially of a gas container (2) positioned within an cavity of an outer package, the gas container containing a gas composition within an internal reservoir of the gas container and being surrounded in the cavity of the outer package by the same gas composition.

Abstract: A method and apparatus for providing a gas to or from a pressurized cylinder is described. The apparatus includes a gas delivery device housing that houses and protects a gas control device configured to deliver gas to a user or device, and may also be adapted to provide gas to the pressurized cylinder in a refilling process. The housing includes a surface free from unnecessary depressions and/or protrusions to facilitate cleanability and enhance safety during use. Adjustment indicators and status indication elements disposed in or on portions of the housing are configured to enhance readability and recognition, which facilitates safe and efficient operation of the device. Adjustable elements to control a flow metric from the gas control device are adapted to facilitate adjustment by a user with a large hand and/or a user suffering from some diminished physical capability.

Abstract: The present invention provides a system for filling a syringe with a small amount of a more precisely mixed medical gas mixture, the system comprising two or more sources for gas, a device for mixing the gases, a means for connecting the gas sources to the device for mixing the gases, a filter system and a syringe. The present invention further provides for a process for filling a syringe with a small quantity of a thoroughly mixed medical gas mixture comprising at least a first gas and a second gas. The process comprises the steps of providing at least a first gas and a second gas, injecting the gases into a device for mixing to form a thoroughly mixed medical gas mixture, filtering the medical gas mixture, and filling a syringe with the required amount of medical gas mixture.
