CA 2625354

The invention relates to a medical device for producing oxygen, wherein the device comprises means for providing first conditions, and means for changing said first conditions to second conditions, the device being configured to during a charging phase extract oxygen from air by, under said first conditions, bringing said air (A) into contact with an agent (SfF) constituted by a reversibly oxygen-fixating agent, i.e. an oxygen selective material, such that the oxygen of the air is adsorbed by said agent, and to remove nitrogen under said first conditions, and configured to during a discharging phase release the oxygen from the agent by means of changing said first conditions to said second conditions. The invention also relates to a method for producing oxygen for individual medical purposes.

La présente invention concerne un dispositif médical permettant de produire l'oxygène. Ce dispositif comprend un moyen permettant d'obtenir des premières conditions, et un moyen permettant de modifier ces premières conditions pour obtenir des secondes conditions. Le dispositif décrit dans cette invention est conçu pour extraire de l'oxygène de l'air au cours d'une phase de chargement, selon un processus qui consiste, dans les premières conditions, à mettre l'air (A) en contact avec un agent (SfF) constitué d'un agent fixant l'oxygène réversible, c'est-à-dire un matériau sélectif pour l'oxygène, de telle sorte que l'oxygène de l'air puisse être adsorbé par l'agent; puis à éliminer l'azote. Le dispositif susmentionné est également conçu pour libérer l'oxygène de l'agent, au cours d'une phase de déchargement, selon un processus qui consiste à modifier les premières conditions pour obtenir des secondes conditions. Cette invention concerne également une méthode permettant de produire de l'oxygène à des fins médicales individuelles.
