Abstract
A device for diagnosing a wound in a patient, the device comprising: at least two electrodes configured to be placed on the skin of the patient, wherein the at least two electrodes are placed in the vicinity of the wound; and at least one signal processor operatively coupled with the at least two electrodes, wherein the at least one signal processor is configured to: i) detect and record an endogenous alternating electrical signal in an area of the wound, ii) transform said endogenous alternating electrical signal into a voltage versus frequency spectrum using a Fast Fourier Transform (FFT) algorithm, and iii) diagnose the wound as a chronic wound if the voltage for a frequency between 65-200 Hz of the frequency spectrum is below 10−7.3±10% volts and as an acute wound if the voltage for a frequency between 65-200 Hz of the frequency spectrum is above 10−7.3±10% volts.
