Abstract
The invention relates to an inserter for an infusion set for intermittent or continuous administration of a therapeutical substance such as e.g. insulin. The inserter comprises a needle unit comprising a needle hub (2) and a carrier body (4), and a cannula housing (3). The cannula housing and the needle hub are releasably connected and when they are connected, the insertion needle (6) is placed inside the cannula (5). The carrier body guides the movement relative to the set housing between a retracted and an advanced position. When released the needle unit and the cannula housing are forced by a spring unit (13) to an advanced position where the needle and cannula are placed subcutaneously. The object of the invention is to provide a disposable inserter for an infusion set which inserter is easy and safe for the user to handle during use and to dispose of after use.
