CA 2270379

A fluid separation device and in-line orifice mixer system is disclosed. The fluid separation device utilizes a syringe (10), which is used for obtaining a fluid sample such as blood, in a centrifugation device; and further utilizes the syringe as a source of a separated fluid portion for storage and transfer for subsequent applications. The syringe containing the separated portion source, and a second syringe (50) containing a second source, are connected to the in-line orifice mixer device. The mixer device (44) comprises a plurality of orifice walls (58) each providing an orifice nonaligned with adjacent orifices to homogeneously mix the plurality of components. The mixer device may further comprise an exit orifice wall with one or more orifices for discharge of the homogeneous mixture.

Cette invention se rapporte à un dispositif de séparation de fluides et à un système mélangeur à paroi ajourée en ligne. Ce dispositif de séparation de fluides utilise une seringue (10), qui sert à obtenir un échantillon de fluide comme du sang, dans un dispositif centrifugeur; et il utilise en outre cette seringue comme source d'une partie de fluide séparée en vue de son stockage et de son transfert pour des applications ultérieures. La seringue contenant la source de partie séparée et une seconde seringue (50) contenant une seconde source sont raccordées au dispositif mélangeur à paroi ajourée en ligne. Ce dispositif mélangeur (44) comporte plusieurs parois ajourées (58) ayant chacune un orifice non aligné sur les orifices adjacents, afin de mélanger de manière homogène la pluralité des constituants. Ce dispositif mélangeur peut en outre comporter une paroi ajourée de sortie ayant un ou plusieurs orifices servant à décharger le mélange homogène.
