ABSTRACT:
A blood-flow probe utilizing two-terminal integrated circuit temperature transducers each of which produces an output current proportional to the absolute temperature of the probe contact plate with which the temperature transducer is associated. One such temperature transducer monitors the temperature of the cold plate of the probe. The other temperature transducer monitors that of the hot plate. Each transducer output signal is carried from the probe so that the temperature of the hot plate and of the cold plate may be independently measured. The hot plate temperature is monitored and maintained at a safe level so as not to endanger the patient by causing tissue damage.
