Title (EN) CONTINUOUS SAMPLE DELIVERY PERISTALTIC PUMP
(FR) POMPE PÉRISTALTIQUE DE DÉLIVRANCE D'ÉCHANTILLONS CONTINUE
Abstract:
(EN) A method and apparatus for pumping fluid through tubing are provided. The method includes orbiting first rollers around the periphery of a first disk at a first tangential speed in a first angular sector and a slower, second tangential speed in a second angular sector, orbiting second rollers around the periphery of a second disk at the second tangential speed, and increasing the pressure of fluid in tubing between one first roller and one second roller by causing the one first roller to fully compress the tubing at the first tangential speed and simultaneously causing the one second roller to fully compress the tubing at the second tangential speed. The apparatus includes a first disk with a recess in its periphery, the first angular sector with a nominal first radius, and a second angular sector with a nominal second radius; and a second disk with the nominal first radius and a recess in its periphery.
(FR) L'invention concerne un procédé et un appareil pour pomper un fluide à travers une tubulure. Le procédé met en œuvre le fait de mettre en orbite des premiers rouleaux autour de la périphérie d'un premier disque à une première vitesse tangentielle dans un premier secteur angulaire et à une seconde vitesse tangentielle plus lente dans un second secteur angulaire, le fait de mettre en orbite des seconds rouleaux autour de la périphérie d'un second disque à la seconde vitesse tangentielle, et l'augmentation de la pression de fluide dans une tubulure entre un premier rouleau et un second rouleau par le fait d'amener le premier rouleau à comprimer complètement la tubulure à la première vitesse tangentielle et d'amener simultanément le second rouleau à comprimer complètement la tubulure à la seconde vitesse tangentielle. L'appareil comprend un premier disque avec un creux dans sa périphérie, le premier secteur angulaire avec un premier rayon nominal, et un second secteur angulaire avec un second rayon nominal; et un second disque avec le premier rayon nominal et un creux dans sa périphérie.
