Abstract:
A centrifugation configuration for centrifugally separating a composite fluid into at least two of the component fluid parts thereof, said configuration being adapted to receive a composite fluid from a fluid source and adapted to provide for the delivery of at least one separated fluid component to a separated component fluid receiver, said configuration having an axis of rotation and comprising:a separation layer having a fluid receiving area adjacent said axis of rotation, said fluid receiving area being adapted to be disposed in fluid communication with a composite fluid source, said separation layer also having; a fluid inlet channel having an inlet channel height; a circumferential fluid separation channel, said separation channel having a proximal end and a distal end; and, a first separated fluid outlet channel having a first height; a second separated fluid outlet channel having a second height, said second outlet channel being adjacent said distal end of said separation channel and said first outlet channel being proximal from said second channel: wherein said inlet channel is disposed in fluid communication with said fluid receiving area; and wherein said circumferential separation channel is disposed in fluid communication with said fluid inlet channel adjacent said proximal end of said separation channel and with each of said separated fluid outlet channels; and wherein at least one separated fluid outlet channels is also adapted to be disposed in fluid communication with a corresponding separated component fluid receiver; and wherein said second height is less than said first height and said first height is less than said inlet channel height.
