摘要： Disclosed is a medical device component for delivering medication fluid to a patient. The medical device component includes a fluid infusion device to regulate delivery of medication fluid, a body-mountable base unit, and a top cover assembly that is removably couplable to the base unit and to the fluid infusion device. The base unit includes a cannula to deliver medication fluid under the control of the fluid infusion device, and a physiological analyte sensor to measure a physiological characteristic. The base unit also includes an electronics assembly electrically connected to sensor leads to obtain measurements in the analog domain, to convert measurements into digital sensor data, and to communicate conditioned digital sensor data to the fluid infusion device. The top cover assembly is configured to provide both fluid and electrical connections for the base unit, by way of an infusion tube having sensor conductors integrated therein or otherwise associated therewith.

摘要： 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.

摘要： 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 an underlying trend. Other example embodiments are disclosed herein.

摘要： 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.
