Medical device for delivering at least one fluid from a medical device

摘要

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.
