Adhesive functional strip for transcutaneous fluorescence measurement
First Claim
Patent Images
1. An adhesive functional strip for transcutaneous fluorescence measurement of general organ functions or metabolic organ disorders by a sensor, characterised in that the strip consists of a laminate of layers in the following order:
- a backing-less transparent transfer adhesive strip or transparent adhesive tape provided on both sides with a pressure-sensitive adhesive coating provided for direct application to the skin;
a transparent film;
at least one light-absorbing pressure-sensitive adhesive layer for absorbing diffused light so that a fluorescence measurement is not disturbed, comprising at least one recess representing an optical window for the sensor to examine the skin; and
a stabilizing transparent cover stabilizing the entire strip.

Abstract
The present invention pertains to a functional patch to be affixed to the skin, with the aim of measuring metabolic disruptions to organs, and general organ functions, of kidneys, liver, heart, pancreas and muscles (lactate), for example—more particularly it concerns the measurement of the glomerular filtration rate (GFR)—and also to a method for producing a functional patch of this kind.
