Abstract: Drug delivery system comprising a main portion with a cap as well as a needle assembly with a needle mounted in a hub and a needle cap releasably mountable on the hub to cover the needle. The cap comprises gripping means reversibly operatable between a first condition in which there is no gripping engagement between the mounted cap portion and the needle cap, this allowing the cap portion to be removed from the main portion without removing the needle cap from the hub, and a second condition in which the cap portion grippingly can engage the needle cap of a needle assembly, this allowing the needle cap to be removed from the hub together with the cap. The cap further comprises user actuation means for operating the gripping means between the two conditions.

Abstract: This invention relates to a method of controlling a dosing operation where a piston in a medical device is moved to a desired position, the dosing operation applies a motor to provide a force from the piston to expel a dose of a liquid medicament, said method comprising the steps of: moving the piston, at a first fixed speed, to a first position of the movement, moving the piston, at a decreasing speed, from said first position to a second position of the movement, and moving the piston, at a second fixed speed, from said second position to the desired position of the movement. The method further comprises the step of letting a fixed waiting time pass, when the piston has reached the desired position. This enables for a precise movement and stop of the piston leading to a precise dose, minimized post dripping and to that only a fixed and short waiting time need to go before a user can withdraw an injection needle of the medical device from his skin.
