Centrifuge fluid container

Abstract

Abstract A fluid container particularly useful in a centrifuge system for separating the various fractions in blood. The container comprises two circular sheets of flexible material, having central openings therein. The outer peripheral edges are sealed together, as well as an annular portion extending outwardly from the central opening. A radial arcuate portion is sealed off, thereby providing an interrupted or discontinuous annular chamber. At one end of the interrupted annular chamber, an inlet tube is provided, extending outwardly from the central opening and communicating with one end of the interrupted annular chamber. At the other end of the interrupted annular chamber, there is provided a radially enlarged portion, which acts as a collection chamber for the various portions of the fluid separated by centrifugal force. The various portions, or fractions, will exist at different radial distances from the center of the bag. A plurality of outlet tubes extend radially outward from the center of the bag to open within the collection chamber at different radial distances. Through these outlet tubes, selected separated portions of the fluid are withdrawn from the bag.
