Abstract: A connector interface system includes a cap to connect to a reservoir to form a reservoir/cap unit for installation into an infusion pump device. The cap has at least one receptacle for receiving one or more detectable features comprising at least one disc-shaped member, for detection by at least one sensor element on the infusion pump device when the reservoir of the reservoir/cap unit is received in a reservoir receptacle of the infusion pump device. The at least one detectable feature has at least one detectable parameter that is associated with one or more characteristics of the cap, the reservoir, the infusion pump device, a cannula associated with the cap or a tubing connected between the cap and the cannula.

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.

Abstract: A user-mountable electronic device includes a housing, an accelerometer located within the housing, and at least one processor located within the housing. The accelerometer measures acceleration of the user-mountable electronic device and is configured to generate an output in response to detecting acceleration of the user-mountable electronic device that is greater than a minimum acceleration threshold. The at least one processor controls operation of the user-mountable electronic device. The at least one processor is configured to receive the output generated by the accelerometer and, in response thereto, to transition from a dormant or standby state of the user-mountable electronic device to an active state of the user-mountable electronic device.

Abstract: A method includes monitoring, via a device including an electrochemical cell, an electrical current that is proportional to an impedance of the electrochemical cell, and responsive to determining that the electrical current satisfies a threshold, measuring, via the device, a plurality of impedances of the electrochemical cell corresponding to a plurality of frequencies. The method further includes determining a charge transfer conductance and a solution resistance based on the plurality of impedances at fewer than four of the corresponding plurality of frequencies and determining the presence of electrochemical interference based on the solution resistance and the charge transfer conductance. The method further includes outputting an alert based on the determination of the presence of electrochemical interference.

Abstract: A fluid delivery system and a fluid conduit assembly suitable for use with the system are disclosed herein. The system includes a fluid infusion pump and a fluid conduit assembly coupled to the pump to deliver medication fluid to a user. The fluid conduit assembly includes a structure defining a flow path for the medication fluid, and a gas trapping filter coupled to the structure and positioned in the flow path. The gas trapping filter functions to filter particulates from the medication fluid and retain gas bubbles from the medication fluid. The structure includes at least one retaining feature to inhibit movement of the gas trapping filter.

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.
