This invention relates to a device such as an injection site or a gateway. The device is placed partly subcutaneously in relation to the patient for as long as e.g. three days and replaces repeated injections by syringes or injection pens. The invention relates to a device for supplying medication comprising a base part (1) and a cannula (4) unreleasably connected to the base part (1). The access opening (6) and at least a part of a through-going opening of the cannula are located in a gate (5) which gate (5) is permanently attached to the base part (1) and movably mounted in relation to the base part (1). The gate (5) has at least one position in which position there is an angle α between a longitudinal central axe (12) of the gate (5) and the longitudinal central axis of the cannula (4) and that the angle α is different from 0° and/or 180°.
