This paper proposes a method for estimating the body temperature using a temperature sensor installed on the inside surface of a blood-pressure cuff. It is known that the skin surface temperature changes with the outside temperature so that the human body temperature is kept constant. In this paper, based on this property, the body temperature is estimated from the skin surface temperature and the outside temperature measured concurrently while the blood pressure is measured. Considering the actual situation, the estimation could be difficult when the temperature of the blood-pressure meter cuff is greatly different from that of upper arm skin, for example. To solve the problem, we classify in advance various learning samples into multiple classes with different sets of parameters to estimate the body temperature.

This paper proposes a method for estimation of a body temperature by using a relation between the upper arm temperature and the atmospheric temperature. Conventional method has measured by armpit or oral, because the body temperature from the body surface is influenced by the atmospheric temperature. However, there is a correlation between the body surface temperature and the atmospheric temperature. By using this correlation, the body temperature can estimated from the body surface temperature. Proposed method enables to measure body temperature by the temperature sensor that is embedded in the blood pressure monitor cuff. Therefore, simultaneous measurement of blood pressure and body temperature can be realized. The effectiveness of the proposed method is verified through the actual body temperature experiment. The proposed method might contribute to reduce the medical staff's workloads in the home medical care, and more.
