Title (EN) A MICROFLUIDIC CARD FOR RBC ANALYSIS
(FR) CARTE MICROFLUIDIQUE POUR ANALYSE DES HEMATIES
Abstract:
(EN) A microfluidic circuit cartridge for a complete blood count, including analyses of red blood cells. Various parameters of the red blood cells may be attained. The cartridge may have sphering mechanism which has a channel or loop with a configuration for reducing or eliminating cell settling. The channel or loop may incorporate a combination of straight and curve paths in the context of gravity. The channel may alternatively have a hydrophilic or hydrophobic inside surface. Again alternatively, the channel may have an electro-wettable inside surface. Or, the channel may be subject to an electric or magnetic field. There may also be a mechanism for reducing or eliminating clumping of a sample.
(FR) La présente invention concerne une cartouche à circuit microfluidique pour une formule sanguine avec analyses des hématies. On obtient plusieurs paramètres concernant les hématies. La cartouche comporte un mécanisme de mise en sphère comportant un canal ou une boucle configurés pour réduire ou éliminer la sédimentation des cellules. Le canal ou la boucle comporte une combinaison de passages droits et courbes dans le contexte de gravité. Sinon, le canal peut avoir une surface intérieure hydrophile ou hydrophobe. Sinon encore, le canal peut avoir une surface intérieure électromouillable. Mais aussi, le canal peut être soumis à un champ électrique ou magnétique. Il peut également y avoir un mécanisme réduisant ou supprimant l'agglutination d'un échantillon.
