Title (EN) SINGLE CAPILLARY TUBE FLUID-COLUMN-OVER-TIME VISCOMETER
(FR) VISCOMETRE A TUBE CAPILLAIRE UNIQUE
Abstract: front page image
(EN) A method and apparatus for determining the viscosity of a non-Newtonian fluid over plural shear rates using a single capillary tube exposed to a continuously decreasing pressure differential and while minimizing the effects of surface tension of that fluid during the determination. A particular application of this method and apparatus is also provided for determining the viscosity of the blood of a living being whereby the single capillary tube initially forms a portion of a hand-held unit that obtains a portion of the circulating blood of the living being; the filled capillary tube is then ejected into an analyzer where the blood therein is exposed to the continuously decreasing pressure differential. Data is generated from the movement of the blood through the capillary tube, due to the decreasing pressure differential, and the blood viscosity is determined from that data.
(FR) L'invention concerne un procédé et un appareil permettant de déterminer la viscosité d'un fluide non newtonien sur plusieurs taux de cisaillement à l'aide d'un seul tube capillaire exposé à un différentiel de pression décroissant de manière continue, tout en minimisant les effets de tension de surface du fluide pendant le processus de détermination. L'invention concerne également, en particulier, une application de ce procédé et de cet appareil servant à déterminer la viscosité du sang d'un être vivant, le tube capillaire unique formant au départ partie d'une unité portable recevant une quantité de sang de l'être vivant. Le tube capillaire plein est alors injecté dans un analyseur dans lequel le sang est exposé au différentiel de pression décroissant, et la viscosité sanguine est déterminée à partir de ces données.
