Title (EN) ASSEMBLY FOR MEASURING THE VISCOSITY OF FLUIDS USING MICROCHANNELS
(FR) ENSEMBLE POUR MESURER LA VISCOSITÉ DE FLUIDES À L'AIDE DE MICROCANAUX
Abstract:
(EN) The present disclosure provides improved viscosity measuring assemblies, and related methods of use. More particularly, the present disclosure provides advantageous measuring assemblies configured to measure the viscosity of samples/fluids (e.g., opaque or transparent liquids) using microchannels. The present disclosure provides for a viscosity measuring assembly (e.g., hand-held electronic measuring assembly) that is configured to measure the viscosity of samples/fluids (e.g., opaque or transparent Newtonian and non-Newtonian liquids, including blood, etc.), in a short period of time (e.g., within a couple of minutes) utilizing only about a droplet of fluid. The viscosity measuring assembly can include a substrate having a microchannel, a light source (e.g., a collimated low coherence light source), and a sensor (e.g., photodiode). The micro-channeled substrate may be disposable, and some of the other components may be reusable since they are substantially not directly exposed to the sample during operation of the viscosity measuring assembly.
(FR) La présente divulgation concerne des ensembles de mesure de viscosité améliorés, et leurs procédés d'utilisation. Plus particulièrement, la présente divulgation concerne des ensembles de mesure avantageux conçus pour mesurer la viscosité d'échantillons/fluides (p. ex., liquides opaques ou transparents) à l'aide de microcanaux. L'ensemble de mesure de viscosité (p. ex., ensemble de mesure électronique portatif) selon la présente divulgation est conçu pour mesurer la viscosité d'échantillons/fluides (p. ex., liquides opaques ou transparents newtoniens et non newtoniens, y compris le sang, etc.), en un court laps de temps (p. ex., en l'espace de quelques minutes) à partir d'à peine une seule gouttelette de fluide. L'ensemble de mesure de viscosité peut comprendre un substrat comportant un microcanal, une source de lumière (p. ex., source de lumière collimatée à faible cohérence), et un capteur (p. ex., photodiode). Le substrat à micro-canal peut être jetable, et certains des autres composants peuvent être réutilisés dans la mesure où ils ne sont pas sensiblement exposés directement à l'échantillon pendant l'utilisation de l'ensemble de mesure de viscosité.
