Medication fluid infusion set component with integrated physiological analyte sensor, and corresponding fluid infusion device

A medical device comprising:

• a fluid infusion device configured to deliver an infusion fluid;
• a body-mountable base unit comprising:
• a base structure;
• a body-insertable cannula for delivery of infusion fluid to a patient, the cannula having an upstream end secured to the base structure and having a downstream end extending from the base structure;
• a body-insertable sensor secured to and extending from the base structure, the sensor facilitating measurement of a physiological characteristic of the patient, the sensor comprising a plurality of electrically conductive leads;
• and
• an electronics assembly having a microprocessor or other digital processing circuit to provide a digital signal corresponding to at least one physiological characteristic measurement facilitated by the sensor;
• and
• a connector assembly that is removably couplable to the body-mountable base unit, the connector assembly comprising:
• a connection structure that releasably mates with the base structure;
• an infusion tube secured to the connection structure, the infusion tube connected in fluid flow communication with the fluid infusion device, the infusion tube extending in a first direction and comprising a terminating end and a slot distal from the terminating end;
• a plurality of electrical conductors carried by or integrated with the infusion tube, the electrical conductors extend through the terminating end;
• a tubing connector coupled in fluid communication with the infusion tube, the tubing connector configured to connect in fluid flow communication with the upstream end of the cannula when the connector assembly is coupled to the body-mountable base unit, the tubing connector comprising:
• a first portion at least partially disposed inside of the infusion tube,
• a second portion extending in a second direction different from the first direction, the second portion extends through the slot, and
• a bend disposed at an intersection between the first portion and the second portion;
• wherein the tubing connector is configured to penetrate a septum of the base structure, and when the septum is penetrated, fluid inside of the infusion tube is directed to flow through the septum into the body-insertable cannula;
• and
• an electrical interconnect assembly coupled to the connection structure, the electrical interconnect assembly establishing electrical connectivity between the electrical conductors and the electrically conductive leads in response to the connector assembly being coupled to the body-mountable base unit;
• wherein the plurality of electrical conductors includes first and second electrical conductors to provide electrical power to the microprocessor or to the other digital processing circuit in response to electrical connectivity is established between the electrical conductors and the electrically conductive leads and in response to the connector assembly being coupled to the body-mountable base unit.
