Abstract
A delivery device and a method for administering a fluid from a fluid reservoir, wherein an unintended free flow of the fluid from the reservoir to a recipient is reliably prevented, are disclosed. The delivery device has a tank for the fluid; a fluid delivery device which delivers the fluid from the tank; a valve body providing an input hole and an output hole; and an infusion set in order to guide the fluid from the tank to a distal end of the delivery device. The delivery device further provides a shutter assembly which is or can be mounted to the valve body and prevents the fluid from flowing inside the infusion set when the fluid exhibits a pressure which is lower than a predefined pressure.
