Abstract (en)
[origin: WO2017103524A1] The present invention relates to a device for treating a biological fluid containing cells suspended in a liquid. The treatment device is intended to be used during a centrifuging step for separating the cells from the liquid. The treatment device includes: a pouch suitable for receiving the biological fluid, the pouch having top and bottom edges that are separated from each other along a longitudinal axis, the pouch being formed of two flexible layers that are placed one on top of the other and are rigidly interconnected along a rigid-connection area, the rigid-connection area being provided so as to form, between both layers, an inner space for receiving the biological fluid and at least one opening suitable for placing the inner space in communication with an outer environment, and at least one sealing member placed in the opening so as to selectively open and close the opening. The treatment device is characterized in that the inner space has: a top portion formed near the top edge and intended for receiving the supernatant liquid of the biological fluid after the centrifuging step, and a neck formed near the bottom edge and intended for receiving a residue of cells from the biological fluid after the centrifuging step. The top portion and the neck each have widths that are measured transversely relative to the longitudinal axis. The width of the neck is less than the width of the top portion.
