Embodiment Construction
[0058] Figure 1-3 One embodiment of an infusion set is shown. The infusion set includes an infusion part OB and a connecting piece OA. The infusion part OB comprises a base 2 having a main plane substantially parallel to the patient's skin when the infusion set is attached to the patient's body. Said base 2 comprises a first set of guides 13 which, in this embodiment, have the form of two stabilizing fins. The base also comprises two retaining means 4 extending from the upper surface of the base, in this embodiment in the form of two steps. On the inner surface of the infusion part, an adhesive support 1, which is an adhesive plaster in this embodiment, is arranged. A cannula 5 extends from the base 2 and penetrates the adhesive support 1 in fluid communication with the central cavity 3 . The cannula 5 is preferably a soft cannula, but can also be made of metal. A cavity 3, optionally covered by a film, is adapted to receive a cannula 6 extending from said connection. e...
