Title
(EN) SYSTEM AND SELF-METERING CARTRIDGES FOR POINT OF CARE BIOASSAYS
(FR) SYSTÈME ET CARTOUCHES DE DOSAGE AUTOMATIQUE POUR DOSAGES BIOLOGIQUES DE POINT D'INTERVENTION
Abstract
(EN) The invention is directed to devices and methods for performing rapid low-cost bioassays in self-contained disposable cartridges that provide efficient mixing of sample and reactants under a layer of liquid wax. Some embodiments additionally use gravity assisted distribution of sample and assay reagents in conjunction with an appliance containing all necessary valves, pneumatic sources, heat sources and detection stations.
(FR) L'invention concerne des dispositifs et des procédés pour effectuer des dosages biologiques rapides à faible coût dans des cartouches jetables autonomes qui fournissent un mélange efficace d'échantillon et de réactifs sous une couche de cire liquide. Certains modes de réalisation utilisent en outre une distribution assistée par gravité d'échantillon et de réactifs de dosage conjointement avec un appareil contenant toutes les vannes, les sources pneumatiques, les sources de chaleur et les stations de détection nécessaires.
