Abstract
The present invention relates to a pre-filled disposable injection device and a needle cannula in combination. The prefilled disposable injection device () is made from a housing () containing a non-exchangeable cartridge () for storing a liquid drug sufficient for a number of injections. The proximal end of the pre-filled injection device () carries the dose setting button () and the distal end carries the needle cannula () having a lumen () through which the settable dose is expelled. The distal end () of the needle cannula () is covered by a telescopic needle covering shield () which shield () can operate between a first position covering the tip () of the needle cannula () and a second retracted position allowing an injection to be performed. The shield () carries a cleaner () which cleans at least the tip () of the needle cannula () between successive injections such that the prefilled injection device can be used without changing the needle cannula () during its life cycle.
