Abstract
The present invention relates to a method and an apparatus for treatment of whole blood comprising two steps, firstly, a step of extracorporeal preseparation whereby the whole blood is separated into a blood plasma rich component and a blood cell rich component and secondly, a step of collecting and/or treating the plasma rich component, e.g. performing dialysis, plasma donation or plasma-pheresis. In one embodiment of the invention, the blood plasma rich component is achieved after particle separation using an ultrasound separator comprising micro-channels formed in a plate structure.

A system for treatment of whole blood, comprising a separation apparatus (10,2200), a treatment apparatus (18) and fluid conduits (1, 15, 17, 19), wherein a first conduit (1) is arranged to transport blood to the separation apparatus (10,2200), characterized in that the separation apparatus (10,2200) comprises a an ultrasound microchannel separator, comprising a plate with a number of channel units formed in a layer of said plate near a first surface, and an ultrasound source arranged in close contact to a second surface, opposing the first surface, devised to separate blood cells from blood plasma, wherein the blood cell rich component is transported from the separation apparatus (10,2200) via a second conduit (12) and in that the blood plasma rich component is transported to the treatment apparatus (18) via a third conduit (19), and in that the treatment apparatus (18) is capable of treating the blood plasma rich component.
A method for treatment of whole blood, comprising the steps of:
- by means of a first conduit (10), supplying blood to a separation apparatus (1,2200);
- by means of the separation apparatus (1,2200), extracorporeally preseparating blood cells from blood plasma;
- by means of a second conduit (20), transporting the blood cell rich component from the separation apparatus (1,2200);
- and
- by means of a third conduit (30) supplying the blood plasma rich component to a treatment apparatus (2).
A blood product produced through a method for treatment of whole blood comprising the steps of:
- by means of a first conduit (10), supplying blood to a separation apparatus (1,2200);
- by means of the separation apparatus (1,2200), extracorporeally preseparating blood cells from blood plasma;
- by means of a second conduit (20), transporting the blood cell rich component from the separation apparatus (1,2200);
- and
- by means of a third conduit (30) supplying the blood plasma rich component to a treatment apparatus (2).
