Methods for analyte sensing and measurement
First Claim
1. A method of measuring an analyte concentration in body fluid in an animal body having skin and subcutaneous soft tissue that includes body fluid, said method comprising:
- (a) providing an analyte measuring device, including;
(i) an analyte sensing element, having a sharpened distal end to facilitate introduction into said animal body and further having an indicating electrode covered by an absorbent or spreading layer forming an outermost, exterior surface of said analyte sensing element;
(ii) an electric power, data processing and display device adapted to mate to said analyte sensing element and activate said analyte sensing element by applying electric power to it and adapted to receive said raw analyte measurement and to compute and display a refined analyte measurement, related to said raw analyte measurement;
(b) introducing said analyte sensing element into said animal body subcutaneous soft tissue, thereby placing said absorbent layer into contact with said animal body subcutaneous soft tissue and said body fluid;
(c) permitting said absorbent layer to become saturated with body fluid;
(d) removing said indicating electrode from said body soft tissue;
(e) activating said analyte sensing element after removing said indicating electrode from said body soft tissue by applying electric power to said analyte sensing element, thereby causing said analyte sensing element to form a raw analyte measurement; and
(f) receiving said raw analyte measurement in said electric power, data processing and display device and computing and displaying a refined analyte measurement, related to said raw analyte measurement.

Abstract
A method of measuring an analyte concentration in body fluid. The method includes the use of an analyte measuring device that has an analyte sensing element with a sharpened distal end and further has an indicating electrode covered by an absorbent layer. Also, an electric power, data processing and display device is adapted to mate to and activate the analyte sensing element by applying electric power to it and adapted to receive the raw analyte measurement and to compute and display a refined analyte measurement from the raw analyte measurement. The analyte sensing element is introduced into the animal body, thereby placing the absorbent layer into contact with the body fluid. The absorbent layer becomes saturated with body fluid and the analyte sensing element is removed from the body and is activated to form a raw analyte measurement. Which which is used to form and display a refined analyte measurement.
