Title (DE) VORRICHTUNG UND VERFAHREN ZUR AUFBEREITUNG VON GASGEMISCHEN
(EN) DEVICE AND METHOD FOR PREPARING GAS MIXTURES
(FR) DISPOSITIF ET PROCEDE DE PREPARATION DE MELANGES GAZEUX
Abstract:
(DE) Die Erfindung betrifft die Aufbereitung von Gasgemischen, insbesondere von Beatmungsgasen fur beatmete Patienten sowie eine Vorrichtung und ein Verfahren dazu, welches die Applikation einer zusatzlichen Gas-Fraktion, speziell von Xenon, im Rahmen eines Gasgemis&sgr;hes, beispielsweise eines Beatmungsgases fur Patienten, besonders einfach und unter mÌglichst geringen Verbrauchsverlusten an Xenon gestattet . Die erf indungsgemasse Aufbereitung betrifft ein Beatmungsgerat (1) tnit einem Intubationsschlauch (2) , einer Gasmischkammer (3) und einem Druckerzeuger (4) , wobei zwischen Intubationsschlauch und Mischkammer ein Selektionselement (5) bezÍglich der Ziel-Fraktion des Beatmungs-Ruckgases von dessen restlichen Fraktionen oder umgekehrt vorhanden ist und ein Ziel-Zufuhranschluss (7) , der mit einem gesteuerten Zufuhrregler (9) mit einem Ziel-Fraktion-Reservoir (10) in Verbindung steht.
(EN) The invention relates to the preparation of gas mixtures, especially respiratory gases for patients needing artificial respiration, and to an associated device and method enabling the application of an additional gas fraction, especially xenon, in a gas mixture, for example, a respiratory gas for patients, in an especially simple manner, with the smallest possible consumption loss of xenon. The inventive preparation involves a respirator (1) comprising an intubation tube (2), a gas mixing chamber (3), and a pressure generator (4). A selection element (5) is provided between the intubation tube and the mixing chamber, for selecting the target fraction of the return respiratory gas from the rest of the fractions or vice versa, in addition to a target supply connection (7) that is connected to a target fraction tank (10) by means of a controlled supply regulator (9).
(FR) L'invention concerne un dispositif et un procédé de préparation de mélanges gazeux, notamment de gaz respiratoires destinés à des patients pratiquant la respiration artificielle. L'invention vise à permettre l'application d'une fraction de gaz supplémentaire, en particulier de xénon, dans le cadre d'un mélange gazeux, par exemple, d'un gaz respiratoire destiné à des patients, de manière particulièrement simple et avec des pertes de consommation de xénon les plus faibles possibles. La préparation selon l'invention concerne un respirateur (1) comprenant un flexible d'intubation (2), une chambre de mélange gazeux (3) et un générateur de pression (4). Un sélecteur (5), placé entre le flexible d'intubation et la chambre de mélange, permet de séparer la fraction cible du gaz de retour respiratoire des fractions résiduelles de ce dernier ou vice-versa. Un raccord d'alimentation cible (7) est en liaison avec un réservoir de fraction cible (10) par un régulateur d'alimentation (9).
