Abstract:
1. A device for preventing the application of excessive pressure to a measurement region in tissue comprising: a probe body having distal and proximal ends, said distal end including a top non-permeable covered portion and a bottom portion defined by a perimeter surface, said perimeter surface defining a recess within said bottom portion; a single sensor responsive to a quantity of analyte to be measured, the sensor being unobstructedly positioned within the recess wherein the sensor is responsive to analyte concentration through a chemical reaction with a reactant; wherein in use said top non-permeable covered portion and said perimeter surface create a covered, isolated measurement area within said recess, said recess containing said analyte, which is thereby prevented from dissipating from the measurement area and further wherein the configuration of the perimeter surface and the position of the sensor within the recess allows said analyte measurement to be free of pressure artifact.
