Abstract: This invention pertains to systems and components useful for infusing medications such as insulin. Typically, the components are used to deliver insulin to a diabetic patient at a site of infusion over a period of time greater than 4 days. The system components typically comprise a cannula adapted for subcutaneous insertion into a diabetic patient. The system further comprises a fluid conduit adapted to deliver the insulin solution from a medication reservoir to the site of infusion and a depot in operable contact with the fluid conduit. The depot comprises selected materials including a site-loss mitigating agent (such as heparin) which inhibits inflammation at the site of infusion, and encapsulation of the cannula at the site of infusion. The site-loss mitigating agent is not premixed with the insulin, and instead is adapted to contact the insulin solution in the depot as the insulin solution flows from the medication reservoir to the site of infusion.

Abstract: A hub member for an infusion set device includes a body and pads configured to receive a squeezing force directed radially inward relative to an axis of the body. The body compresses radially inward relative to the axis in response to the squeezing force. A plurality of connection features on the body are moveable from a first position radially inward toward a second position when the hub member is compressed radially inward. The connection features engage one or more further connection features on a housing to attach the hub member to the housing when the connection features are in the first position, and disengage the further connection features to release the hub member when the connection features are moved toward the second position.

Abstract: A bubble detector, a medical device system that includes the detector, and a related operating methodology are disclosed here. The detector is designed and operated to detect presence of bubbles in a fluid delivery tube. The detector includes a capacitive sensor, a control circuit to control operation of the sensor to measure capacitance associated with fluid in the fluid delivery tube, a power source to provide voltage across the capacitor electrodes and to provide operating power to the control circuit, a communication module to communicate sensor data from the detector, and a housing with structural features to secure the detector to the fluid delivery tube and to maintain the capacitor electrodes in position relative to the fluid delivery tube. The sensor data is indicative of the measured capacitance associated with the fluid in the fluid delivery tube.

Abstract: A cannula includes a tubular body having an axial dimension through which a flow channel extends. The tubular body has a first end for insertion into a subject, and a second end configured to be held within a base of a medical device. The tubular body has a first length portion extending along the axial dimension from the first end toward the second end. A second length portion extends along the axial dimension from the first length portion toward the second end, and has an outer dimension that flares outward to be larger than the outer dimension of the first length portion. The second length portion also has a tubing wall thickness that is greater than the tubing wall thickness of the first length portion.
