Abstract

A medical device for the separation of a concentrate enriched with cells from a biological fluid, in particular a concentrate of stromal or stem cells from medullar aspirate or venous blood, comprises: a treatment container for receiving and treating the biological fluid for the purposes of its separation into a number of fractions; a first collection container, for receiving a first fraction of the fluid, in particular a fraction poor in said cells; a second collection container, for receiving a second concentrated fraction of the fluid enriched with said cells; a deviator valve having a first way connected or prearranged for connection to the treatment container, a second way connected or prearranged for connection to the first collection container, and a third way connected or prearranged for connection to the second collection container; a first line for connection of the treatment container to the first way of the deviator valve, a second line for connection of the first collection container to the second way of the deviator valve, and a third line for connection of the second collection container with the third way of the deviator valve. The treatment container is a syringe container with a plunger having a plunger stem associated in a releasable way to a corresponding plunger head, and the first connection line comprises a first transparent tube, in particular a flexible transparent tube, and at least one of the second and third connection lines preferably comprises a second flexible tube. At least one connection line, or each connection line, further comprises: at least one respective hydraulic connector, for separable connection of a corresponding tube to the corresponding container and/or to the corresponding way of the deviator valve; and at least one automatic-closing or one-way valve.
