SINGLE NEEDLE DEVICE FOR EXTRACORPOREAL TREATMENT OF BLOOD

摘要

The device has occlusion units e.g. pump, activates sampling and return lines to manage alternate sampling and return sequences of blood. A chamber (12) is in fluid communication with a blood extracorporeal circuit having a needle (2). An activation unit (19) activates the chamber for modifying chamber volume by shifting a chamber wall, to accumulate and draw the blood during arterial and venous phases, respectively.
