  • Patent number: 8613726
    Abstract: An external infusion device that infuses a fluid into an individual's body includes a housing, a reservoir, a drive system, a power supply, electrical elements, and a tab. The reservoir contains the fluid, and the drive system forces the fluid from the reservoir. The electrical elements control the power to the drive system to regulate the rate that fluid is forced from the reservoir. The tab mates with the housing, and contains at least one electrical element. The tab is removable, and may be replaced with a different tab. The different tab may change the rate fluid is forced from the reservoir. A tab may be removed from one external infusion device and installed in a different external infusion device. The tab may be limited to use in a predetermined number of external infusion devices and may include a power supply.

  • Publication number: 20120179015
    Abstract: A telemetered characteristic monitor system includes a remotely located data receiving device, a sensor for producing signal indicative of a characteristic of a user, and a transmitter device. The transmitter device includes a housing, a sensor connector, a processor, and a transmitter. The transmitter receives the signals from the sensor and wirelessly transmits the processed signals to the remotely located data receiving device. The processor coupled to the sensor processes the signals from the sensor for transmission to the remotely located data receiving device. The data receiving device may be a characteristic monitor, a data receiver that provides data to another device, an RF programmer for a medical device, a medication delivery device (such as an infusion pump), or the like.

  • Publication number: 20110152658
    Abstract: Disclosed herein are methods and systems for generating an estimate of an in vivo analyte concentration and identifying whether the estimate is aberrant. In some embodiments, the system includes a sensor comprising an analyte sensor and a temperature sensing element, and a control unit programmed to identify changes in temperature that may indicate a non-physiologic condition (and result in an aberrant glucose measurement). In some embodiments, the methods include generating an estimate of analyte concentration at a particular time using the analyte sensor, and generating first and second signals indicative of temperature using the temperature sensing element. In some embodiments the methods include identifying the estimate of analyte concentration as aberrant if the magnitude of the difference between the first and second signals indicative of temperature exceeds a threshold value.

  • Publication number: 20100191086
    Abstract: A system is provided for sensing blood glucose data of a patient. The system includes a sensor, user interface, and an optional auxiliary device. If the connection between the sensor and user interface is by a wire, the sensor remains powered when the wire is disconnected. The communication between the sensor and the user interface may be wireless. The auxiliary device can be a patient monitor or other display or signal device, which displays information about the blood glucose data collected by the sensor. The sensor is connected to sensor electronics, which include a sensor power supply, a voltage regulator, and optionally a memory and processor.
