Abstract
The present invention relates to an electric medical thermometer for measuring temperature of patients in cavity. The electric medical thermometer comprises a temperature detecting set, including a temperature detecting element, for capturing temperature signals and a temperature calculating device for temperature signals processing. By combining a primary sampling frequency with a secondary sampling frequency, where the primary sampling frequency is greater than the secondary sampling frequency, the temperature calculating device translates temperature signals captured from the temperature detecting device into a temperature measurement. The underlining method of the present invention is realized by imitating the physiology of the heart beat pulse, which serves as a resource engine of thermal compensation and as an example for the sampling frequency in order to attain more precise and reliable temperature measurement. Utilizing the primary sampling frequency, the temperature calculating device will recognize the timing of temperature inflection points with temperature values. Continuing, an approximation of heart beat pulse estimated after calculation will be imposed as the secondary sampling frequency, which is then used to obtain a more precise and more reliable temperature measurement in body temperature measuring.
