Inserter
First Claim
1. An inserter for an angled infusion set;
- the inserter comprising;
a set housing provided with first guiding means on an internal surface for guiding the movement of a carrier body, the carrier body is provided with second guiding means on an external surface for guiding the movement relative to the set housing between a retracted and an advanced position;
a cannula housing comprising a soft cannula to be placed subcutaneously,a needle hub comprising an insertion needle for piercing of the skin, the cannula housing and the needle hub are releasably connected to each other, and when they are connected, the insertion needle is adjoined to the cannula, the needle hub and the carrier body are provided with unreleasable interacting locking means;
a spring unit connected to release means and when the release means are activated, the cannula housing, the needle hub and the carrier body are forced by the spring unit to an advanced position where the needle and cannula can be placed subcutaneously; and
a projecting portion extending from a lower base of the set housing, the projecting portion forming an angle in relation to an axis extending in a longitudinal direction of the insertion needle indicating the correct insertion angle for the user during insertion, the projecting portion extending across the axis in front of an end of the cannula when the needle hub is in the retracted position such that the projecting portion lifts up at least a portion of a mounting pad relative to the lower base to a position for contacting the skin during insertion.

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 and a carrier body, and a cannula housing. The cannula housing and the needle hub are releasably connected and when they are connected, the insertion needle is placed inside the cannula. 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 to an advanced position where the needle and cannula are placed subcutaneously. One 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.
