Abstract: Disclosed are methods, apparatuses, etc. for glucose sensor signal stability analysis. In certain example embodiments, a series of samples of at least one sensor signal that is responsive to a blood glucose level of a patient may be obtained. Based at least partly on the series of samples, at least one metric may be determined to assess an underlying trend of a change in responsiveness of the at least one sensor signal to the blood glucose level of the patient over time. A reliability of the at least one sensor signal to respond to the blood glucose level of the patient may be assessed based at least partly on the at least one metric assessing the underlying trend. Other example embodiments are disclosed herein.

Abstract: An insertion set system includes a base configured to be secured to a patient, and a flexible tubing on the base. The flexible tubing has a distal end portion forming a cannula to be inserted into the patient. An inserter having a needle is received by the base. The needle has a channel in which the distal end portion of the flexible tubing is received. The needle is able to slide relative to the flexible tubing, to selectively withdraw the needle off of the distal end portion of the flexible tubing. The base may include a passage for fluid flow arranged transverse to the axial dimension of the distal end portion of the flexible tubing.

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: Medical devices and related augmented reality systems and methods are provided. A method of operating an infusion device involves analyzing one or more images captured by an imaging device to identify image content indicative of an activity capable of influencing the physiological condition of the patient and in response to identifying the activity based at least in part on the one or more images, automatically adjusting delivery of the fluid to the patient based at least in part on the activity. An expected nutritional characteristic for a meal is determined based at least in part on the image content, and a delivery adjustment for delivering the fluid is determined based on the expected nutritional characteristic. A graphical indication of the delivery adjustment may also be provided using augmented reality.

Abstract: A flexible, fluid flow tubing is configured to be kink resistant, and a medical device is configured with such kink resistant tubing. The tubing has a length L and a circular cross-section shape taken perpendicular to the length dimension. The tubing has an inside radius r and an outside radius R, wherein L/R≥34.8, and wherein R/r≥1.5. The tubing may be made of a polyether block amide (PEBA) or other thermoplastic elastomer (TPE). The tubing may be received in a channel of a hollow needle, wherein the needle is slideable in the axial dimension relative to the tubing, to selectively slide off of at least a portion of the tubing.
