Title
(EN) NON-VENTING BODILY FLUID SAMPLE OPTIMIZATION DEVICE AND SYSTEM
(FR) DISPOSITIF ET SYSTÈME D'OPTIMISATION D'ÉCHANTILLON DE LIQUIDE CORPOREL NON VENTILÉ
Abstract
(EN)
A fluid sample optimization device for optimizing a fluid sample includes an inlet, an outlet, a sample path connected between the inlet and the outlet, and a contaminant containment reservoir connected between the inlet and the outlet. The contaminant containment reservoir includes an air permeable fluid resistor proximate the outlet, and is arranged to receive, when a pressure differential is applied between the inlet and the outlet, a first portion of the fluid sample to displace air therein through the air permeable fluid resistor and the outlet, such that upon receipt of the first portion of the fluid sample and containment of the contaminants in the contaminant containment reservoir, subsequent portions of the fluid sample can be conveyed by the sample path from the inlet to the outlet when subsequent pressure differentials are applied between the inlet and the outlet.
(FR)
L'invention concerne un dispositif d'optimisation d'échantillon de liquide permettant d'optimiser un échantillon de liquide, ledit dispositif comprenant une entrée, une sortie, un trajet d'échantillon relié entre l'entrée et la sortie, et un réservoir de confinement de contaminants relié entre l'entrée et la sortie. Le réservoir de confinement de contaminants comprend une résistance de liquide perméable à l'air à proximité de la sortie, et est conçu pour recevoir, lorsqu'un différentiel de pression est appliqué entre l'entrée et la sortie, une première partie de l'échantillon de liquide pour déplacer l'air s'y trouvant à travers la résistance de liquide perméable à l'air et la sortie, de telle sorte que lors de la réception de la première partie de l'échantillon de liquide et du confinement des contaminants dans le réservoir de confinement de contaminants, des parties suivantes de l'échantillon de liquide peuvent être transportées par le trajet d'échantillon de l'entrée à la sortie lorsque des différentiels de pression ultérieurs sont appliqués entre l'entrée et la sortie.
