摘要: In some embodiments, an apparatus may comprise a first insertion needle and a second insertion needle. The first insertion needle may be configured to carry a first medical device (e.g., a sensor) through an opening in an apparatus housing. The second insertion needle may be configured to carry a second medical device (e.g., a cannula) along a curved path that passes through the opening in the apparatus housing such that a distal end of the first medical device becomes increasingly displaced from the distal end of the second medical device as the distal end of the second medical device is carried along the curved path.

摘要: A continuous glucose monitoring system may utilize externally sourced information regarding the physiological state and ambient environment of its user for externally calibrating sensor glucose measurements. Externally sourced factory calibration information may be utilized, where the information is generated by comparing metrics obtained from the data used to generate the sensor's glucose sensing algorithm to similar data obtained from each batch of sensors to be used with the algorithm in the future. The output sensor glucose value of a glucose sensor may also be estimated by analytically optimizing input sensor signals to accurately correct for changes in sensitivity, run-in time, glucose current dips, and other variable sensor wear effects. Correction actors, fusion algorithms, EIS, and advanced ASICs may be used to implement the foregoing, thereby achieving the goal of improved accuracy and reliability without the need for blood-glucose calibration, and providing a calibration-free, or near calibration-free, sensor.

摘要: Disclosed herein are techniques related to insertion of a fluid conduit (e.g., tubing connected to a fluid reservoir or a cannula sharing a pre-assembled fluid pathway with such tubing). In some embodiments, an insertion mechanism may include one or more springs (e.g., a torsion spring or a compression spring). The one or more springs may cause a trocar or a trocar slider to pierce tissue and insert the fluid conduit. The one or more springs may further cause the trocar or the trocar slider to be removed from the tissue.

摘要: A diagnostic Electrochemical Impedance Spectroscopy (EIS) procedure is applied to measure values of impedance-related parameters for one or more sensing electrodes. The parameters may include real impedance, imaginary impedance, impedance magnitude, and/or phase angle. The measured values of the impedance-related parameters are then used in performing sensor diagnostics, calculating a highly-reliable fused sensor glucose value based on signals from a plurality of redundant sensing electrodes, calibrating sensors, detecting interferents within close proximity of one or more sensing electrodes, and testing surface area characteristics of electroplated electrodes. Advantageously, impedance-related parameters can be defined that are substantially glucose-independent over specific ranges of frequencies. An Application Specific Integrated Circuit (ASIC) enables implementation of the EIS-based diagnostics, fusion algorithms, and other processes based on measurement of EIS-based parameters.

摘要: A system includes one or more processors, and one or more processor-readable storage media storing instructions which, when executed by the one or more processors, cause performance of: switching operation of an infusion device from a first mode of fluid delivery to a second mode of fluid delivery, the first mode being different from the second mode, receiving user input after the infusion device is operating in the second mode, the user input being indicative of whether the infusion device should remain operating in the second mode or transition from the second mode to a different mode, and operating the infusion device in a manner that is influenced by the user input.
