Electronic wiring substrate
First Claim
1. An improved electronic wiring board having a nonconducting substrate, temperature sensor and at least one analyte sensor supported, in close relation, one to the other, on the same side of said substrate and a heater, also supported on the substrate, and located on another side of said substrate from the temperature sensor and analyte sensor to provide heat in response to temperature sensed by said temperature sensor to at least the region where said temperature sensor and said analyte sensor are positioned on said substrate to thereby control the temperature of said region of said board within a narrow distribution of temperatures, and connecting means supported on said substrate for connecting said board to an external electrical source.

Abstract
An improved electronic wiring board having a thermistor and at least one blood gas sensor supported, in close relation, one to the other, on one side of the board and a heater supported on the other side of the board to provide heat in response to temperature sensed by the thermistor, to at least the region where the thermistor and the blood gas sensor are positioned on the board to control the temperature of the region of the board within a narrow distribution of temperatures.
