Title
(EN) LIGHT GUIDE FOR FLUID TESTING CELLS
(FR) GUIDE DE LUMIÈRE POUR DES CELLULES DE TEST DE FLUIDE
Abstract
(EN)
In one example, testing cells extend along a length of a slot. Each testing cell includes a microfluidic channel extending from the slot, a pump to move fluid from the slot into the channel, a discharge nozzle through which fluid exits the channel, a fluid discharger to discharge fluid from the channel through the nozzle and a photosensor. A light guide is provided to receive light from an external light source and is to serially transmit the light to the microfluidic channel of each of the plurality of testing cells.
(FR)
La présente invention porte, dans un exemple, sur des cellules de test qui s'étendent sur toute la longueur d'une fente. Chaque cellule de test comprend un canal microfluidique qui s'étend depuis la fente, une pompe destinée à déplacer un fluide depuis la fente dans le canal, une buse d'évacuation à travers laquelle un fluide sort du canal, un dispositif d'évacuation de fluide destiné à évacuer un fluide du canal à travers la buse et un photodétecteur. La présente invention comprend un guide de lumière destiné à recevoir une lumière provenant d'une source lumineuse externe et est destiné à transmettre en série la lumière au canal microfluidique de chaque cellule de test de la pluralité de cellules de test.
