Abstract
A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

40. An apparatus for supplying a fluid to a body of a patient and for monitoring a body characteristic of the patient, the apparatus comprising:
-
a base adapted to secure the apparatus to the skin of a patient; a first piercing member coupled to and extending from the base, wherein the first piercing member is operatively coupled to at least one cannula for infusing a fluid to an infusion site; a second piercing member coupled to and extending from the base and operatively coupled to an electrochemical sensor having a sensor electrode for determining at least one body characteristic of the patient at a sensor placement site; wherein the first and second piercing members are coupled to the base in an orientation such that when the first and second piercing members are operatively coupled to the base and inserted into a patient, a first perforation channel made by the first piercing member is not in operable contact with a second perforation channel made by the second piercing member. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 50, 51, 52)

55. A method for inhibiting interference of an electrochemical sensor that monitors a body characteristic of a patient, wherein the interference is caused by a interferant present in an infusate infused by an apparatus for supplying a fluid to a body of a patient, the method comprising supplying a fluid to a body of a patient using an apparatus comprising:
-
a base adapted to secure the apparatus to the skin of a patient; a first piercing member coupled to and extending from the base, wherein the first piercing member comprises at least one cannula for infusing a fluid to an infusion site, a second piercing member coupled to and extending from the base and including the electrochemical sensor having a sensor electrode for determining at least one body characteristic of the patient at a sensor placement site, wherein the first and second piercing members are coupled to the base in an orientation such that when the first and second piercing members are inserted into a patient, a first perforation channel made by the first piercing member is not in operable contact with a second perforation channel made by the second piercing member such that a fluid infused to the infusion site cannot flow through the first perforation channel or the second perforation channel to the sensor; so that interference is inhibited. - View Dependent Claims (56)

59. An apparatus for supplying a fluid to a body of a patient and for monitoring a body characteristic of the patient, the apparatus comprising:
-
abuse adapted to secure the apparatus to the skin of a patient; a piercing member coupled to and extending from the base and having a first and a second lumen;
whereinthe first lumen comprises an outlet adapted to infuse a fluid to an infusion site; the second lumen comprises an electrochemical sensor disposed therein, wherein the electrochemical sensor comprises a sensor electrode for determining at least one body characteristic of the patient at a sensor placement site and a window that exposes the sensor to the body of the patient; and the outlet of the first lumen and the window of the second lumen are arranged in an orientation such that when the piercing member is operatively coupled to the base and inserted into a patient, an infusate is infused from the orifice at a site that is least 7 millimeters from the window of the second lumen. - View Dependent Claims (60, 61, 62, 64)
