Abstract:
1. A device for separation of fluid from blood, the device comprising: a separation medium comprising a plurality of short large-diameter fibers comprising a diameter of from about 13 microns to about 20 microns, and a length of about from 5 mm to 9 mm and a plurality of long small-diameter fibers comprising a diameter of from about 5 microns to about 8 microns, and a length of from about 6 mm to about 20 mm displaying partial order by way of similar orientation of fibers that are close together, the separation medium being in the form of a layer such that, the plurality of short large-diameter fibers and the plurality of substantially aligned long small-diameter fibers in the layer are substantially coplanar and form a first size of pores suitable for migration into a plane and a second size of pores suitable for migration in a direction substantially along the plane, wherein there are fewer of the short large-diameter fibers than the long small-diameter fibers; a reinforcing material impregnating a bottom side of the separation medium to form a composite, wherein a hot melt adhesive couples the reinforcing material to the separation medium; a proximal portion of the separation medium for receiving blood; and a distal portion of the separation medium for providing fluid from blood.
