Abstract
The invention relates to a subcutaneous infusion device comprising a housing; a flow channel within the housing; a cannula extending from the housing and being in flow communication with the flow channel; a connector for delivery of fluid into the flow channel; guide means for guiding the connector into a delivery position; the guide means being being arranged axis-symmetrically in relation to the axis needle along which the needle extends. By providing the guide means in such a manner there is no longer a need for an angular positioning of the connector in relation to the housing since guiding function is provided in any angular position of the connector in relation to the housing.
