Abstract

Un casete de bomba que comprende una membrana externa flexible cubriendo las trayectorias de flujo, cámaras de válvula y cámaras de bomba del casete están diseñadas para accionarse por un empaque de control sobre una unidad base dispuesta para mover la válvula designada y porciones de bomba de la membrana de casete; el desempeño de una válvula de casete puede mejorarse optimizando la configuración de la región de control de válvula del empaque de control que yace encima de la válvula de casete; esto puede mejorar el flujo de fluido a través de la válvula y reducir la cantidad de ruido vibratorio asociado con la abertura de la válvula; el control de válvula de empaque o región de accionamiento está unido al menos parcialmente por un canal de vacío que se orienta hacia el lado externo del empaque de tal manera que puede aplicarse un vacío constante entre el control de válvula de empaque o región de accionamiento y la porción adyacente de la membrana de casete; una versión mejorada el canal de vacío comprende una pared interna flexible (contigua con la región de control de válvula) de tal manera que la pared interna se flexiona o colapsa parcialmente lejos del asiento de válvula de casete, mientras aún mantiene permeabilidad del canal de vacío durante la aplicación de presión negativa sobre la región de accionamiento de válvula de empaque para abrir la válvula de casete.
