Claim:
1. A method for delivering a therapeutic substance to a patient, the method comprising: providing a device comprising a connector of a conduit for carrying the therapeutic substance, a first structural part with a cannula extending therefrom for positioning in a body of the patient and formed by a plate element and a central body, a second structural part with a connection port for detachably coupling to the connector of the conduit, wherein the first structural part and the second structural part are connected to one another such that they are inseparable, can be rotated relative to one another and in a selected rotational position to form a channel for introducing the therapeutic substance from the connection port to the cannula, and wherein the connection port is designed such that the movement of the coupling and uncoupling of the conduit takes place in a direction transverse to the longitudinal axis of the cannula, and wherein the second structural part has a spring-elastic latching arm which rests on a corrugated surface contour of the plate element to form a ratchet mechanism such that the first structural part and second structural part can be rotated relative to one another when the connector is not set on the connection port; and applying the device to the patient's body so that the cannula is positioned in the body; operably coupling a supply of the therapeutic substance to the conduit; and causing the therapeutic substance to flow into the patient's body.
