The invention concerns a method of taking a biological fluid, in particular blood, with an anticoagulant and/or preservation solution added, in which the biological fluid is taken by natural flow and the anticoagulant and/or preservation solution is added by pumping, the said method making provision for measuring the flow of fluid taken and slaving the pumping speed to the measured flow, so as to obtain continuously during sampling a given ratio between the quantity of fluid taken and the quantity of anticoagulant and/or preservation solution added. The invention also concerns the sampling machine (1) and the bag system (2) for implementing the said method.
L'invention porte sur une méthode permettant de prélever un liquide biologique, en particulier le sang, en ajoutant un anticoagulant et/ou une solution de conservation. On prélève le liquide biologique en mettant à profit le flux sanguin naturel et on ajoute un anticoagulant et/ou une solution de conservation au moyen d'une pompe, ladite méthode étant conçue pour mesurer le débit du liquide prélevé dans le but d'adapter la vitesse de la pompe en fonction du débit mesuré afin d'obtenir de façon continue un ratio donné entre la quantité de liquide prélevé et la quantité d'anticoagulant et/ou de solution de conservation ajoutées au cours de l'échantillonnage. L'invention concerne également l'appareil (1) et un système de sac (2) permettant d'appliquer ladite méthode.
