Development of an electronic equipment for the pre medical diagnose in the progress of diabetic foot disease

This paper presents an instrument that uses electronic technologies to characterize the effects of diabetes by measuring the changes of the tissue physical characteristics, mainly in the foot. The instrument comprises 1) the measurement of glucose, 2) IR temperature measurement of the foot, 3) the differentiation of staining in areas of the foot, 4) the determination of the elasticity of vessels and foot tissues, 5) the determination of muscle impedance, 6) the recording of the variation of the patient heart rate, 7) software that concentrates the digital information of the measured characteristics of the foot and a display to show the information to the physician. This article describes the results of temperature measurement on the sole of a foot, the patient result storage, a measurement method with RF impedance and the temperature of the foot taken with a commercial IR camera.
