Method and apparatus for presentation of noninvasive glucose concentration information
View Patent ↗The invention relates generally to the extraction and/or presentation of glucose concentrations estimated as a function of time into a format that facilitates conveyance of the underlying information. More particularly, glucose concentration histories are presented in terms of risk of behavior, in a video format, and/or in an audio format. The reduction of data into video format, selected by time period, cluster, or glucose concentration response, into an animated or video presentation allows diagnosis and treatment information to be more readily determined and used. Alternatively, glucose concentrations are output through a voice synthesizer or an earcon. These information presentations are useful for both the medical professional and the end user. The information presentation is preferably used with a noninvasive, implantable, semi-continuous, and/or continuous analyte analyzer, such as a glucose concentration analyzer.
