Claim 0:
1. A temperature monitoring system comprising:
a first temperature measuring device configured to be disposed at a first location associated with a patient;
a second temperature measuring device;
a first thermal block comprising a first material having a first thermal conductivity and a second material having a second thermal conductivity different than the first thermal conductivity, the first thermal block having a first total thermal conductivity based on at least the first thermal conductivity and the second thermal conductivity, wherein at least a portion of the first thermal block is disposed between the first and second temperature measuring devices, the first temperature measuring device configured to measure a first temperature associated with the patient at the first location, the second temperature measuring device configured to measure a second temperature through the at least the portion of the first thermal block;
a third temperature measuring device configured to be disposed at a second location associated with a patient;
a fourth temperature measuring device;
a second thermal block having a second total thermal conductivity, wherein at least a portion of the second thermal block is disposed between the third and fourth temperature measuring devices, the third temperature measuring device configured to measure a third temperature associated with the patient at the second location, the fourth temperature measuring device configured to measure a fourth temperature through the at least the portion of the second thermal block; and
one or more processors configured to receive temperature measurements from the first, second, third, and fourth temperature measuring devices, and based on the received temperature measurements, the first and second total thermal conductivities, a first distance between the first and second temperature measuring devices, and a second distance between the third and fourth temperature measuring devices, determine a skin thermal resistance of the patient and a core body temperature of the patient, wherein the determined core body temperature is based on at least the determined skin thermal resistance.
