Abstract

A method for generating a signal shape (w1) for an electro-stimulation signal (w1) for healing wounds by electro-stimulation by way of an electrode (E1) which has an encoding member (6) with a code word (cw) which identifies therapeutic treatments, and is coupled to indicators (i1, i2) which indicate which treatments have to be activated. The signal shape (w1) is formed systematically from base signals capable of being parameterized such as a DC signal and two pulse trains, the parameters and the timing of which are formed systematically and applied where necessary, in accordance with the combined therapies. The generation of signal shapes for a plurality of electrodes is also disclosed.

Dependent claims

A method for generating a signal shape (w1) of an electro-stimulation signal to be supplied to an electrode (E1) for healing wounds by electro-stimulation, the method comprises the following steps:

a) the connection of an electrode (E1) to a signal shape generator (23), wherein the electrode (E1) is connected to an encoding member (6) in which a code word (cw) is stored, wherein the code word (cw) comprises at least two code word portions (c1, c2, . . . ), and wherein each code word portion identifies a respective therapeutic treatment (tb1, tb2, . . . ), and wherein each code word portion haves coupled to them a respective indicator (i1, i2, . . . ) indicating whether the therapeutic treatment (tb1, tb2, . . . ) associated with the respective code word portion should be activated or not;
b) the retrieval from the encoding member (6) of the code word portions (c1, c2, . . . ) and the associated indicators (i1, i2, . . . );
c) checking whether a first indicator (i1) coupled to a first code word portion (c1) of the retrieved code word portions indicates activation,
and if the first indicator (i1) indicates activation, the retrieval of a first signal (s1) associated with the therapeutic treatment (tb1) identified by the first code word portion and the formation of a temporary signal shape (w) on the basis of the first signal (s1),
and if the first indicator (i1) does not indicate activation, passing on to step d);
d) for each further code word portion (c2, c3, . . . ) of the retrieved code word portions, checking each time whether the further indicator (i2, i3, . . . ) which is coupled to the further code word portion (c2, c3, . . . ) indicates activation,
and each time if the further indicator (i2, i3, . . . ) indicates activation and the temporary signal shape (w) is formed, the retrieval of a further signal (s2, s3, . . . ) associated with the further therapeutic treatment (tb2, tb3, . . . ) identified by the considered further code word portion (c2, c3, . . . ), and the further formation of the temporary signal shape (w) on the basis of the temporary signal shape (w) and the further signal (s2, s3, . . . ),
and each time if the further indicator (i2, i3, . . . ) indicates activation and the temporary signal shape (w) is not yet formed, the retrieval of a further signal (s2, s3, . . . ) associated with the further therapeutic treatment (tb2, tb3, . . . ) identified by the considered further code word portion (c2, c3, . . . ), and the formation of the temporary signal shape (w) on the basis of the further signal (s2, s3, . . . ),
and each time if the further indicator (i2, i3, . . . ) does not indicate activation and the signal shape (w) is formed, the maintaining of the temporary signal shape (w);
e) the generation of the signal shape (w1) on the basis of the temporary signal shape (w) after all the further code word portions have been treated;
characterized in that before said signal shape is generated the temporary signal shape is checked in order to establish whether or not the temporary signal shape falls within therapeutic limits of the therapeutic treatments identified by each of the signals on which the temporary signal shape was formed, said temporary signal shape being adjusted so as to fall within said therapeutic limits if it has been established that it did not fall within said therapeutic limits.
