  • Patent number: 10025909
    Abstract: A configuration management resource keeps track of incremental updates to a locally stored copy of configuration information (such as drug library information) used by a medical device to administer treatment to patients. The medical device retrieves a copy of the configuration information from a configuration management resource. Unbeknownst to a user of the medical device, to ensure that the medical device has most up-to-date configuration information, the medical device communicates a request for updates to the configuration management resource. To service the received request for updated configuration information, the configuration management resource forwards incrementally available configuration update information to the requesting medical device. The medical device uses the received configuration update information from the configuration management resource to update its local version of configuration information stored in the medical device.

  • Patent number: 10004442
    Abstract: Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

  • Patent number: 9999724
    Abstract: A system and method for a patch-like, self-contained substance infusion device (700) which can be attached to a skin surface via an adhesive contact surface. A push button (780) activation assembly can then be used to remove an interlock (730), allowing a disk or Belleville spring (735) assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly (710). This allows the release of one or more spring-loaded patient needles (760) into the skin surface, and establishes a fluid communication path between the patient needles (760) and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button (780) activation assembly further allows the release of one or more improved safety mechanisms (794) after use.

  • Patent number: 9977010
    Abstract: Systems and methods for processing sensor data and end of life detection are provided. In some embodiments, a method for determining the end of life of a continuous analyte sensor includes evaluating a plurality of risk factors using an end of life function to determine an end of life status of the sensor and providing an output related to the end of life status of the sensor. The plurality of risk factors may be selected from the list including the number of days the sensor has been in use, whether there has been a decrease in signal sensitivity, whether there is a predetermined noise pattern, whether there is a predetermined oxygen concentration pattern, and error between reference BG values and EGV sensor values.
