Abstract

Embodiments of the invention provide a dual insertion set for supplying a fluid to a body of a patient and for monitoring a body characteristic of the patient. Typical embodiments of the invention include a base, an infusion portion coupled to a first piercing member and a sensor portion coupled to a second piercing member. The infusion portion includes a cannula coupled to the first piercing member for supplying the fluid to a placement site. The sensor portion includes a sensor coupled to and extending from the base having at least one sensor electrode formed on a substrate and is coupled to the second piercing member in a manner that allows the sensor to be inserted at the placement site. The base is arranged to secure the dual insertion set to skin of the patient. Typically the first and second piercing members are arranged such that when the first and second piercing members are operatively coupled to the base, they are disposed in a spatial orientation designed to inhibit sensor interference that may be caused by compounds present in fluids infused through the cannula.
