A collection of devices designed to prepare platelet-rich plasma (PRP) or platelet-rich fibrin matrix (PRFM) from an autologous blood specimen for application to soft-tissue wounds and injured bone to accelerate healing and/or achieve haemostasis. It includes single- or double- (concentric) barrel syringe(s) with connecting tubes and caps. Blood is collected by venous puncture and processed in a centrifuge, increasing the concentration of platelets within the plasma or fibrin matrix; this may be done at the point-of-care. This is a single-use device.
