Title
(EN) A SEMIPERMEABLE ARRANGEMENT
(FR) AGENCEMENT SEMI-PERMÉABLE
Abstract
(EN) A semipermeable arrangement for use in clinical, agricultural, industrial and/or environmental settings. The semipermeable arrangement has a structural arrangement formed from a material such as ePTFE that has an affinity to a lubricating fluid such as perfluorocarbon. The structural arrangement may be infused with a lubricating fluid such that the semipermeable arrangement resists fouling. The semipermeable arrangement is further arranged with barriers to prevent or limit the movement of the lubricating fluid through at least part of the structural arrangement. The semipermeable arrangement further has passageways that are free from the presence of, and/or cannot be infused with, lubricating fluid. The passageways permit the movement of fluids such as air, water and dissolved substances through the structural arrangement. The semipermeable arrangement is thereby both self-cleaning and porous and has a wide range of uses.
(FR) L'invention concerne un agencement semi-perméable destiné à être utilisé dans des environnements cliniques, agricoles, industriels et/ou environnementaux. L'agencement semi-perméable comprend un agencement structural formé à partir d'un matériau tel que l'ePTFE qui a une affinité pour un fluide lubrifiant tel que le perfluorocarbone. L'agencement structural peut être infusé avec un fluide lubrifiant de telle sorte que l'agencement semi-perméable résiste à l'encrassement. L'agencement semi-perméable est en outre agencé avec des barrières pour empêcher ou limiter le mouvement du fluide lubrifiant à travers au moins une partie de l'agencement structural. L'agencement semi-perméable comporte en outre des passages dans lesquels ne se trouve pas de fluide de lubrification et/ou qui ne peuvent pas être infusés avec un fluide de lubrification. Les passages permettent le mouvement, à travers l'agencement structural, de fluides tels que l'air, l'eau et des substances dissoutes. L'agencement semi-perméable est ainsi à la fois auto-nettoyant et poreux et présente une large gamme d'utilisations.
