Title
(EN) USE OF A SELECTIVE MEMBRANE IN A BIOMEDICAL DEVICE FOR THE EXTRACORPOREAL TREATMENT OF BLOOD AND OTHER ORGANIC FLUIDS
(FR) UTILISATION D'UNE MEMBRANE SELECTIVE DANS UN DISPOSITIF BIOMEDICAL POUR LE TRAITEMENT EXTRA-CORPOREL DU SANG ET D'AUTRES FLUIDES ORGANIQUES
Abstract
(EN)
The present invention relates to the use of a selective membrane (3) in a biomedical device (1) for the extracorporeal ozonization of blood and biological fluids. The device (1) used in the treatment comprises a hollow body (2) in which there are two compartments (blood compartment: 4') for the passage of two fluids; the compartments are separated by a membrane (3) which is made of polymeric resin for the selective molecular diffusion of ozone and/or oxygen and is substantially inert with respect to ozone.
(FR)
L'invention concerne l'utilisation d'une membrane sélective (3) dans un dispositif biomédical (1) pour l'ozonisation extra-corporelle du sang et de fluides biologiques. Le dispositif utilisé pour ce traitement comprend un corps creux (2) contenant deux compartiments (compartiments à sang : 4) destinés au passage de deux fluides. Ces compartiments sont séparés par une membrane (3) constituée de résine polymère pour la diffusion moléculaire sélective d'ozone et/ou d'oxygène, laquelle membrane est sensiblement inerte par rapport à l'ozone.
