1. A monitoring system for frequently measuring an analyte present in a subject and providing to said subject self-monitoring of said analyte, said monitoring system comprising:
- (A) a first component to be placed in contact with a skin or mucosal surface of said subject comprising(i) a sampling mechanism for transdermally extracting the analyte from the subject, wherein said sampling mechanism is adapted for extracting the analyte across a skin or mucosal surface of said subject;
(ii) a sensing mechanism in operative contact with the analyte extracted by the sampling mechanism, wherein said sensing mechanism obtains a signal from the extracted analyte and said signal is specifically related to an amount or concentration of analyte; and
(iii) a first mechanism for providing operative communication with a second component of the monitoring system, wherein (a) said operative communication comprises wireless communication technology employing electromagnetic waves, and (b) said first and second components are separately housed; and
(B) the second component comprising(i) a user interface;
(ii) a second mechanism for providing operative communication with the first component, wherein (a) said operative communication comprises wireless communication technology employing electromagnetic waves, (b) the second component receives the signal from the first component, and (c) is capable of communicating with a third component remote from the subject being monitored without communicating with the first component;
(iii) a computing mechanism that converts the signal from the extracted analyte to an output indicative of the amount or concentration of analyte extracted by the sampling mechanism;
(iv) a visual display said output to the subject;
(v) an alarm that produces tactile and/or auditory signals to warn the subject when the amount or concentration of analyte is above a pre-set threshold value or below a pre-set threshold value; and
(vi) the second component configured to be worn by the subject on a wrist of the subject or a belt of the subject, or configured to be carried by the subject as a credit-card-type unit or a pager-type unit.

Abstract
Devices and methods are provided for frequently measuring the concentration of an analyte present in a biological system. A monitoring system having at least two components is employed in order to allow separation of data collection from data processing and display. Such separation allows greater flexibility and convenience for the user.

23. A method for self-monitoring of analyte present in a subject, the method comprising the steps of:
-
(a) placing a first component in contact with a skin or mucosal surface of the subject; (b) transdermally extracting analyte from the skin or mucosal surface of the subject, by the first component; (c) obtaining a signal, by the first component, specifically related to an amount or concentration of the analyte; (d) providing the subject a second component adapted to be worn or carried; (e) wirelessly communicating, using electromagnetic waves, between the first component and the second component; (f) receiving, by the second component, the signal obtained in step (c) from the first component; (g) computing, by the second component, the amount or concentration of the analyte extracted by the first component; (h) visually displaying to the subject a warning, by the second component, if the amount or concentration of analyte is above or below a pre-set threshold value; and (i) audibly alarming the subject, by the second component, if the amount or concentration of analyte is above or below a pre-set threshold value. - View Dependent Claims (24, 25)
