Abstract
A device for separating and recovering blood fractions includes two conical chambers communicating via their bases, the first chamber having a duct for supplying the fluid to be treated and means for recovering at least one component, the second chamber comprising an elastically deformable flexible membrane that transversely separates a space opening into the duct for communicating with the second chamber, and a bag having a volume that varies according to the deformation of the membrane.
Claims7
A device for recovering components of blood from a blood sample, the device comprising:
- a first conical chamber having a first end and a second end, the first end having a first cross sectional area and the second end having a second cross sectional area narrower than the first cross sectional area;
- a second conical chamber having a third end and a fourth end, the third end having a third cross sectional area and the fourth end having a fourth cross sectional area wider than the third cross sectional area, the second end adjacent and facing the third end;
- a fluid pathway extending from the second end to the third end;
- a duct for introducing fluid into the first conical chamber;
- a flexible membrane covering an opening at the fourth end and configured to adjust component levels by elastically deforming;
- and
- a conduit comprising a valve within the conduit and configured to selectively recover at least one component of the blood from the fluid pathway.
