A dual insertion set includes a base (40) , an infusion portion (30) , a sensor portion (20) , and at least one piercing member (24, 34) . The base is adapted to secure the dual insertion set to the skin of a patient . The infusion portion includes a cannula (33) for supplying a fluid to a placement site. The cannula is coupled to and extends from the base and has at least one lumen with a distal end for fluid communication with the placement site . The cannula has at least one port structure formed near another end of the lumen opposite the distal end. The sensor portion includes a sensor (22) coupled to and extending from the base having at least one sensor electrode formed on a substrate. The sensor is for determining a body characteristic, e.g. the glucose level, of the patient at the placement site. The at least one piercing member is coupled to and extends from the base to facilitate insertion of the cannula and the sensor. |
