  • Publication number: 20200178799
    Abstract: An analyte monitoring system may include an analyte sensor, a transceiver, and a display device. The transceiver may be configured to operate in two or more modes of operation. The display device may be configured to communicate with the transceiver. The two or more modes of operation may include a clinical mode in which the transceiver receives first sensor data from the analyte sensor and calculates one or more first analyte levels using at least the received first sensor data but does not convey the one or more first analyte levels to the display device. The two or more modes of operation may include an unblinded mode in which the transceiver receives second sensor data from the analyte sensor, calculates one or more second analyte levels using at least the received second sensor data, and conveys the one or more second analyte levels to the display device.

  • Patent number: 9241660
    Abstract: The present invention provides an insertion device and method for implanting a biosensor into a patient subject. In one embodiment, a biosensor is stored in the instrument's hydration chamber which enables the biosensor to maintain proper hydration and sterilization prior to insertion. The instrument further includes a plunger that travels along a channel within the support device. After the biosensor is placed into the channel, the user pushes the plunger causing the biosensor to move through the channel and a hollow tube and into the patient subject. The present invention also provides for packaging and storing a biosensor and insertion device so that the biosensor is hydrated and sterile prior to insertion.

  • Patent number: 7190445
    Abstract: An optical sensor device for determining the presence or concentration of an analyte, contains a waveguide disposed over a light source and a light detector mounted on a surface of a substrate and separated by an internal baffle, wherein the waveguide has a thickness corresponding to a far field emission point of the light source as determined by a light shielding baffle between the light source and light detector. An analyte indicator matrix is disposed on the outer surface of the waveguide. The sensor device geometry takes advantage of only direct illumination of the indicator matrix, and direct collection of indicator matrix illumination, without any significant reflection by said waveguide. Undesirable light noise generated by the light source passes directly out of the device through the waveguide.
