Method and assembly for the generation of signal shapes for healing wounds by electro-stimulation

A method for generating signal shapes of electro-stimulation signals to be supplied to electrodes for healing wounds by micro-current electro-stimulation, the method comprising the steps of:

• a) connecting a first electrode to a first port of a signal shape generator, wherein the first electrode is connected to a first encoding member in which a first code word is stored, the first code word identifying at least one first therapeutic treatment to be applied by the first electrode,
• b) connecting a second electrode to a second port of the signal shape generator, wherein the second electrode is connected to a second encoding member in which a second code word is stored, the second code word identifying at least one second therapeutic treatment to be applied by the second electrode,
• c) connecting a central contact to a third port of the signal shape generator, the central contact being provided for contact with skin and for use as a return channel of microcurrents which are applied by the electrodes,
• d) positioning the first and second electrodes and the central contact for treatment of at least one wound,
• e) retrieving from the first and second encoding members the first and second code words,
• f) retrieving at least one first signal associated with the at least one first therapeutic treatment identified by the first code word and the formation of a first temporary signal shape on the basis of the at least one first signal,
• g) retrieving at least one second signal associated with the second therapeutic treatment identified by the second code word and the formation of a second temporary signal shape on the basis of the at least one second signal,
• h) checking the first and second temporary signal shapes in order to establish whether or not the combination of the first and second temporary signal shapes falls within therapeutic limits of the therapeutic treatments identified by the code words,
• i) adjusting at least one of the first and second temporary signal shapes so as to fall within the therapeutic limits if it has been established that the combination of the first and second temporary signal shapes did not fall within the therapeutic limits, and
• j) forming, by the signal shape generator, first and second wound healing electro-stimulation signals on the basis of respectively the first temporary signal shape and the second temporary signal shape and applying the first and second wound healing electro-stimulation signals to respectively the first electrode and the second electrode, the first and second wound healing electro-stimulation signals being micro-current signals having an amplitude of less than 1 mA,
• wherein at least one of the first and second code words comprises at least four code word portions, wherein the first code word portion identifies an antibacterial treatment, the second code word portion identifies a cell migration treatment, the third code word portion identifies a treatment for pain and/or a treatment for the increase in the oxygen tension TcPO2, and the fourth code word portion identifies a stimulation of one or more processes selected from the group consisting of ATP production, DNA production, protein production, and amino acid absorption.
