Patent

CA 2619471

The invention relates to device for enriching and depleting materials in a liquid. Said device comprises a pump for advancing the liquid and said pump comprises a displaceable transport element (1) which transports the liquid. Said device is advantageous in that it comprises an insertable and retractable transport and drive unit and it is particularly advantageous in that the flow guiding element effectively enriches and depletes material in the liquid. The invention also relates to a fluidic rotor bearing for mounting the transport element. It is also possible to connect a two lumen cannula by means of a concentric connection module. Due to said device, a compact oxygen generator system, which is based on an integrated and re-usable blood-pump, is produced which can be used in blood.

L'invention concerne un dispositif pour enrichir et/ou appauvrir un fluide en substances. Ce dispositif comprend une pompe pour acheminer ledit fluide, cette pompe présentant un élément de refoulement (1) mobile refoulant le fluide. Ce dispositif se caractérise de façon avantageuse par une unité de refoulement et d'entraînement extensible et rétractable et par un écoulement particulier permettant d'enrichir et/ou d'appauvrir de façon efficace le fluide en substances. Un support de rotor fluidique est par ailleurs utilisé pour supporter l'élément de refoulement. Un module de raccordement concentrique peut être utilisé également pour connecter une canule à deux lumières. Ce dispositif permet de créer, en particulier lorsqu'il est utilisé pour le sang, un système oxygénateur compact reposant sur une pompe à sang intégrée et réutilisable.
