CA 2391960

A system for collecting whole blood includes a metering chamber (72) and a reservoir (74). A movable gasket or seal (16) is positioned to a fill position, and whole blood is added to the metering chamber (72) until the metering chamber (72) is full. Then the gasket (16) is moved to a closed position, thereby moving blood from the metering chamber (72) to the reservoir (74) and sealing the reservoir (74). A diluting liquid contained in the reservoir (74) is mixed with the whole blood to dilute and stabilize the whole blood in the reservoir (74) for later analysis of one or more selected blood components.

L'invention concerne un système de collecte de sang entier comprenant une chambre de mesure et un réservoir. Un joint d'étanchéité mobile est positionné en position de remplissage et le sang entier est ajouté dans la chambre de mesure jusqu'à ce que cette dernière soit pleine. Ensuite le joint statique est déplacé en position fermée, déplaçant ainsi le sang de la chambre de mesure vers le réservoir, puis ce dernier est fermé de manière étanche. Un liquide diluent renfermé dans le réservoir est mélangé avec le sang entier afin de diluer et de stabiliser le sang entier dans le réservoir pour une analyse ultérieure d'un ou de plusieurs composants sélectionnés du sang.
