The invention relates to a medical device and a method for delivering at least one fluid from a medical device. More particularly, the present patent application relates to medical devices for delivering at least one, in particular two drug agents from separate reservoirs. The technical problem of preventing after-dripping and at the same time improving the safety and the dose accuracy of a medical device is solved by a method for delivering at least one fluid from a medical device, wherein the fluid is ejected from a reservoir by an advancing movement of a bung, wherein an electromechanical device is instructed to move the bung via a piston over a predetermined distance and wherein, after a dwell time following the advancing movement of the piston, the piston is retracted by the electromechanical device. The technical problem is also solved by a medical device, in particular for performing a method according to the invention, comprising a reservoir, a bung, a piston an electromechanical device and a control unit. |
