  • Device for handling blood in extracorporeal blood circulation
    Patent number: 8133195
    Abstract: In a device for handling blood in extracorporeal blood circulation that has at least one oxygenator, one heat exchanger, and one blood filter, the inlets and outlets in the oxygenator/heat exchanger unit are embodied such that a blood flow cross section of A?80 mm2, preferably A?120 mm2, is assured. The device can also be operated in an isolated form as a single structural part, which takes on the functions of an oxygenator and a heat exchanger with a blood filter. If a pump is provided in the device, then the pump drive can be removed as needed.

  • Vensous bubble trap
    Patent number: 7798985
    Abstract: In a venous bubble trap (1), having a housing (2) to which fluid, in particular blood, can be delivered essentially tangentially via a fluid inlet (8) and from which fluid can be carried away via a fluid outlet (10), and having a filter device (3) located in the interior of the housing (2), the filter device (3) divides the housing interior into a prefilter region (5) and a postfilter region (6), and the postfilter region (6) surrounds the prefilter region (5) in at least some portions. As a result, air is reliably removed from the fluid.
