Title (EN) DIFFUSION BARRIER IN A DELIVERY APPARATUS FOR PRESSURISED MEDICAL LIQUIDS
(FR) BARRIÈRE DE DIFFUSION DANS UN APPAREIL DE DISTRIBUTION DESTINÉ À DES LIQUIDES MÉDICAUX SOUS PRESSION
Abstract:
(EN) A delivery apparatus for pressurised medical liquids comprising a reservoir (1) for medical liquid and a pressurising means (3,10,12) configured for pressurising medical liquid to a driving pressure; with a diffusion barrier (20) arranged to float on medical liquid (2) in the reservoir (1) and disposed to cover substantially the whole surface of the medical liquid (2) in the reservoir (1) for the purpose of preventing diffusion of gas present in the reservoir (1) into the medical liquid (2).
(FR) La présente invention concerne un appareil de distribution destiné à des liquides médicaux sous pression comprenant un réservoir (1) destiné à un liquide médical et un moyen de mise sous pression (3, 10, 12) configuré pour mettre sous pression le liquide médical à une pression motrice ; une barrière de diffusion (20) est disposée pour flotter sur le liquide médical (2) dans le réservoir (1) et disposée pour recouvrir sensiblement la totalité de la surface du liquide médical (2) dans le réservoir (1) dans le but de prévenir la diffusion de gaz se trouvant dans le réservoir (1) dans le liquide médical (2).
