ABSTRACT:
A reusable cable apparatus for interfacing disposable temperature probes with a patient monitor. One reusable cable connects a thermocouple probe to the patient monitor and has a phone plug connection wherein a cold junction and cold junction compensation is located. A second reusable cable connects a thermistor probe to the patient monitor through a similar phone plug. Circuit means in the patient monitor receives either phone plug and produces an output signal which is substantially the same regardless of whether the thermocouple and first reusable cable or thermistor and second reusable cable are connected. The effect of secondary thermocouple junctions in interconnecting connector shells is substantially eliminated by connecting lead wires to contact pins such that the secondary junctions are physically close to one another.
