US 2017/0361000 A1 · APPARATUS FOR EXCHANGING MATERIAL BETWEEN BLOOD AND A GAS/GAS MIXTURE

Abstract

The invention relates to an apparatus for exchanging material between blood and a gas/gas mixture, comprising a chamber (1) through which blood can flow and in which a plurality of material-permeable fiber tubes is provided, the gas/gas mixture being flowable through the fiber tubes, blood being flowable around the fiber tubes. At least one deformable element (9) is provided in the chamber (1) in addition to the fiber tubes, through which the gas/gas mixture can flow, this deformable element being deformable and restorable, in particular compressible out of a relaxed shape and restorable to a relaxed shape by pressure fluctuations acting on the at least one element (9) externally, in particular pressure fluctuations transmitted by the blood in the chamber (1).

Dependent claims

An apparatus for exchanging material between blood and a gas/gas mixture, the apparatus comprising:

a chamber through which blood can flow;
a plurality of elongated material-permeable fiber tubes extending along an axis in the tube;
means for flowing the gas/gas mixture through the fiber tubes;
and the blood around the fiber tubes,
at least one deformable element around which the blood can flow in the chamber, the deformable element being deformable and restorable by pressure fluctuations acting externally on the at least one element from the blood in the chamber for providing a windkessel effect to which end the at least one element is compressible from a relaxed shape, during a n systolic increase in blood pressure and during a diastolic decrease of the blood pressure is restorable to the relaxed shape.
