摘要：
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.
