Abstract
A device and method for processing a biological fluid comprises directing the biological fluid tangentially or parallel to the face of a separation medium in at least one serpentine fluid flow channel such that a plasma-rich fluid passes through the separation medium and a plasma-depleted fluid passes tangentially to the surface of the separation medium.
Claims14
A method for processing a biological fluid comprising:
- directing a biological fluid tangentially to the surface of a separation medium in at least one serpentine fluid flow channel whereby plasma-rich fluid passes through the separation medium and plasma-depleted fluid passes tangentially across the separation medium.
A device for removing plasma from a biological fluid comprising:
- a housing having an inlet and first and second outlets and defining a first fluid flow path comprising at least one serpentine fluid flow channel between the inlet and the first outlet and a second fluid flow path between the inlet and the second outlet;
- and
- a separation medium positioned inside the housing tangentially to the first fluid flow path and across the second fluid flow path, the separation medium being suitable for passing plasma therethrough.
