Integrated receiver for continuous analyte sensor

a continuous analyte and receiver technology, applied in the field of systems and methods for monitoring glucose, can solve the problems of reducing the accuracy of smbg tests, increasing the error within the calibrated sensor value, and reducing the accuracy of continuous devices, so as to reduce errors, simplify or fewer components, and less prone to human error

Benefits of technology

[0005]A continuous glucose sensor that includes simpler or fewer components than prior art sensors, that is user friendly, that exhibits reduced error within the calibrated sensor values, and / or is less prone to human error is desirable.
[0027]In an aspect of the third embodiment, the device further comprises at least one bioprotective film that is adapted to stretch or stick onto the sensing region to protect the sensing region from damage, clogging, or contamination from a biological fluid.

Problems solved by technology

Therefore, the use of a continuous device can be cumbersome, particularly when the user is away from home.
Furthermore, continuous sensors have conventionally been calibrated using a reference glucose monitor that uses different measurement technology than that of the continuous sensor, which can increase the error within the calibrated sensor values.
Unfortunately, such SMBG tests have an error of ±20% and additionally cannot be calibrated by the user.
Furthermore, because the reference measurement device (for example, SMBG) is independent from the continuous glucose sensor, the possibility of accuracy in reporting time of SMGB can be prone to human error.

Embodiment Construction

[0067]The following description and examples illustrate some exemplary embodiments of the disclosed invention in detail. Those of skill in the art will recognize that there are numerous variations and modifications of this invention that are encompassed by its scope. Accordingly, the description of a certain exemplary embodiment should not be deemed to limit the scope of the present invention.

[0068]Definitions

[0069]In order to facilitate an understanding of the preferred embodiments, a number of terms are defined below.

[0070]The term “continuous glucose sensor,” as used herein, is a broad term and are used in its ordinary sense, including, without limitation, a device that continuously or continually measures glucose concentration, for example, at time intervals ranging from fractions of a second up to, for example, 1, 2, or 5 minutes, or longer. It should be understood that continuous glucose sensors can continually or continuously measure glucose concentration without requiring us...

Abstract

A system is provided for monitoring glucose in a host, including a continuous glucose sensor that produces a data stream indicative of a host's glucose concentration and an integrated receiver that receives the data stream from the continuous glucose sensor and calibrates the data stream using a single point glucose monitor that is integral with the integrated receiver. The integrated receiver obtains a glucose value from the single point glucose monitor, calibrates the sensor data stream received from the continuous glucose sensor, and displays one or both of the single point glucose measurement values and the calibrated continuous glucose sensor values on the user interface.
