摘要： Generally, methods, devices, and systems related to analyte monitoring and data logging are provided—e.g., as related to in vivo analyte monitoring devices and systems. In some aspects, methods, devices, and systems are provided that relate to enable related settings based on an expected use of an in vivo positioned sensor; logging or otherwise recording analyte levels acquired or derived—e.g., sample analyte levels more frequently than they are logged or otherwise recorded in memory; dynamically adjust the data logging frequency; randomly determine times of acquiring or storing analyte levels from the in-vivo positioned analyte sensors; and enable recording related settings when the system is operable.

摘要： Glucose and ketones may be dysregulated singularly or concurrently in certain physiological conditions and may be advantageously assayed together using an analyte sensor capable of detecting both analytes. Certain analyte sensors capable of dual detection may comprise a first working electrode and a second working electrode, a ketones-responsive active area disposed upon a surface of the first working electrode, a glucose-responsive active area comprising a glucose-responsive enzyme disposed upon a surface of the second working electrode, a membrane having a first portion overcoating the ketones-responsive active area and a second portion overcoating the glucose-responsive active area, in which the first portion and the second portion have different compositions. The ketones-responsive active area comprises an enzyme system comprising at least two enzymes that are capable of acting in concert to facilitate detection of ketones.

摘要： System for managing a patient's glucose level including a glucose sensor to generate raw data signals for measurements of the patient's glucose level. The system further includes sensor electronics operatively coupled to the glucose sensor. The sensor electronics have a memory storing one or more predetermined characteristics associated with the sensor electronics. The sensor electronics are in electronic communication with the glucose sensor. The system further includes a receiving device and external devices, wherein the external devices include a first disposable device and a second disposable device. Each external device is configured for wireless communication with both the receiving device and the sensor electronics. The system enables the transfer of sensor context information from the first disposable device to the second disposable device.

摘要： Embodiments described herein include a device and a computer program product. The device includes one or more processors, an analyte sensor, a temperature sensor, a communication module, and memories. The processors are configured to generate external temperature of the analyte sensor measured by the temperature sensor corresponding to a first time, to calculate a sensitivity adjustment of the senor based on the temperature data, to add the sensitivity adjustment corresponding to the first time to a total sensitivity adjustment, and to determine whether the first time is below a predetermined time threshold, and if so, to generate external temperature data corresponding to a second time and to calculate an interval between the second time and the first time. The processors are further configured to determine if the first time is equal to the predetermined time threshold, and if so, to store the total sensitivity adjustment in an OTP memory.

摘要： Method and system for providing basal profile modification in insulin therapy for use with infusion devices includes periodically monitoring the analyte levels of a patient for a predetermined period of time in order to determine, based on the monitored analyte levels, an appropriate modification factor to be incorporated into the underlying basal profile which was running at the time the periodic monitoring of the analyte levels were performed.

摘要： Physiological parameters that related to the kinetics of red blood cell hemoglobin glycation, red blood cell elimination, and red blood cell generation within the body of a subject can be used, for example, to calculate a more reliable calculated HbA1c (cHbA1c), adjusted HbA1c (aHbA1c), and/or a personalized target glucose range, among other things, for subject-personalized diagnoses, treatments, and/or monitoring protocols. Such physiological parameters may be determined using a model that considers cross-membrane glucose transport and glycation.

摘要： Methods of compensating for ambient temperature using temperature sensors, the method comprising: sampling at a first sampling rate, with a processor, first temperature measurements from a first temperature sensor on an on-body sensor. Then determining, with a processor, first ambient-compensated temperatures from the first temperature measurements; and determining, with a processor, final ambient-compensated temperatures by applying a correction gain or factor to the first ambient-compensated temperatures. Wherein the correction gain or factor changes value at a slower rate than the sampling rate.
