Abstract
An infusion device for medical use has a container designed to hold a specified quantity of a liquid to be infused into a patient, a weighing device associated for operation with the container to measure the weight of the container and emit a corresponding signal, a transport line connected to the container, a pump, and a control unit associated with the weighing device and with the pump. The control unit is capable of detecting the end of infusion condition and of commanding the pump to stop the transport of fluid. A separator for continuously separating fluid into a gaseous portion and a liquid portion operates in the infusion line downstream of the pump and prevents the infusion of gas during the stopping transient of the pump at the end of infusion.
