Abstract
Provided is an improved disk oxygenator having a hollow median longitudinal shaft with a plurality of orifices to allow oxygen to be diffused radially through a cylindrical reservoir. Also provided is a disk oxygenator with a hollow longitudinal shaft comprised of a series of disks. The disks are provided with a central annular cylindrical passageway.
Claims11
A blood oxygenator comprising:
- a. a horizontally disposed cylindrical reservoir having a first end and a second end;
- a. a first cap, closing said first end, having a lower blood inlet and an upper gas outlet;
- b. a second cap closing said second end;
- c. a hollow median shaft attached to said caps, disposed longitudinally within said cylindrical reservoir, said shaft provided with a plurality of orifices;
- d. an oxygen providing means attached to one end of said shaft to allow oxygen to enter said shaft axially and centrally and to be diffused radially through said orifices and into said reservoir;
- e. a plurality of disks attached to said shaft;
- and
- f. a means for rotating said shaft about its longitudinal axis.

- b) a first cap having a lower blood inlet and an upper gas outlet, closing said first end;
- c) a second cap closing said second end;
- d) a plurality of disks having cylindrical annular central segments interfitting with segments of an adjacent disk, interfitting of said disks forming a hollow, longitudinal passageway in an assembly of disks, said disks being formed with orifices and said assembly of disks and longitudinal passageway being located within said cylindrical reservoir, said longitudinal passageway being attached to said caps,
- e) an oxygen providing means attached to one end of said passageway to allow oxygen to be introduced centrally and axially into said hollow passageway wherein the oxygen is dispersed radially through the orifices;
- and
- f) a means for rotating said assembly of disks about its longitudinal axis.
