  • Publication number: 20210121620
    Abstract: An extracorporeal blood treatment device comprises a single housing defining an internal blood flow cavity. The housing accommodates an oxygenator, a heat exchanger and an additional mass transfer assembly, each having an array of fluid conduits. The arrays are co-located within the internal blood flow cavity such that blood flowing through the internal blood flow cavity flows substantially homogeneously around all the conduits. The arrays are arranged relative to one another within the internal blood flow cavity such that they together define a continuous blood flow path through the internal blood flow cavity along which blood can flow. The continuous blood flow path has a blood entry surface at one end and a blood exit surface at the opposite end. The overall blood flow direction from the blood entry surface along the blood flow path to the blood exit surface follows substantially a straight line.

  • Patent number: 9226999
    Abstract: The present invention relates to methods for coating at least one surface of a medical device for improving the hemocompatibility of said surface. Further, the invention relates to medical devices comprising surfaces, coated with a coating composition containing a nonionic ester formed from an acyclic C3-C6(OH)3-6 polyol and from at least three C12-C26 fatty acids, and further includes at least one hydrophilic group.

  • Publication number: 20110098646
    Abstract: The invention relates to a method of establishing and optimizing, in a perfusion system with two independently regulatable pumps, at least two independently regulatable circulations which are interconnected via at least two junction points and contain substantially the same fluid, in particular blood, blood plasma or electrolyte solutions. The perfusion system may comprise any standard devices such as those for pumping, transfer, flow or pressure regulation, filtration, bubble elimination, substance and energy exchange, or measurement of physical/chemical parameters of the fluid.
