摘要： A medical device for separating a fluid, in particular for separating platelet-rich plasma from whole blood, includes three containers and at least one corresponding connection line having an intermediate bifurcation. Provided on the connection line are valve means for enabling or preventing a flow of fluid. At least one container includes a hollow container body and a plunger associated in a movable way to the container body. The device also includes a filtering member on the connection line.

摘要： 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.

摘要： A medical device for separating a fluid, in particular for separating platelet-rich plasma from whole blood, includes three containers and at least one corresponding connection line having an intermediate bifurcation. Provided on the connection line are valve means for enabling or preventing a flow of fluid. At least one container includes a hollow container body and a plunger associated in a movable way to the container body. A modular structure has modules connected to enable separation thereof. A first module includes at least the first container and a corresponding portion of the first connection line, and a second module, which has at least one between the second and third containers with a corresponding portion of the first connection line. Provided at least at the interface between two modules of the modular structure are releasable connectors, in particular hydraulic connectors having at least two parts that can be coupled together, each of which belongs to a corresponding module.
