DESCRIPTION:
BRIEF SUMMARY
The present invention concerns a device for physiotherapy comprising means for the realization of iontophoresis with medicament crystals frozen at temperatures between 0.degree. C. and -5.degree. C.
It is already well known that the electrophoresis (or iontophoresis) process consists of in the local penetration through the skin of the patients of medicament ions, in distillate water solutions, by means of the passage of electric currents between two electrodes applied to the part to be treated.
This known process, however, shows many limits and contraindications: the skin may occur; therefore be active is a minimum percentage of the whole, so that the doses cannot be computed precisely due to the dispersion of the special sponges; and also according to the sweating level of the patient reacting to contact with the electrode.
It is the aim of the present invention to eliminate or reduce the above mentioned contraindications by means of a combination of the electrophoresis with the method of the cryotherapy, which at present is used for local lowering of the temperature in traumatized parts.
The aim set forth is reached by means of the device for physiotherapy according to the present invention, comprising an electric current generator with variable and in case modulated frequency, supplied between two electrodes that comprise the sick anatomic part to be treated, the first electrode consisting of a container for a medicament solution in distillate water brought to the freezing point, and the other one in an element with a wide surface that may be applied to the skin for closing the electric circuit, by means of the passage of the current through the anatomic part, consisting of the flow of ions coming from the frozen medicament crystals, so that nearly the whole of the ions penetrate through the anatomic part being treated, directly reaching the activity areas.
The advantages of the device according to the present invention are many and considerable: means of a contact provided in the container, to the cathode as well as to the anode, according to the polarity of the ions; the skin allows the circulation of a current intensity higher than the one of the conventional iontophoresis, without causing burns or other; whole treatment, as all ions and only those present in the crystal are translated into the electric current, while the pure melted solvent will be collected while running down the skin; operator onto the skin with the ionic frozen crystal, any Ph-value alteration of the skin is prevented; contusion trauma, as no burn and/or abrasion occurs; and ion-crystals is kept at a temperature of about -5.degree. C. during the treatment, making the ions penetrate in the deepest structures of the anatomic parts.
The device and the process according to the present invention may be applied to all cases of local treatment of pathologies that may be treated with active ions, and in particular in the following cases:
The present invention will be described in detail hereinbelow with reference to the drawings in which a preferred embodiment is shown, and in which:
FIG. 1 shows, in an axonometric and transparency view, the container for the medicament in distillate water, with the internal contact for the electric connection;
FIG. 2 shows the structure of the electrode, consisting of the medicament frozen to ion crystals, without the upper part of the container; and
FIG. 3 shows the electric and functional scheme of the complete device.
The figures show the device for iontophoretic physiotherapy with frozen medicament crystals, comprising: which the medicament in solution will dissociate, consisting of a container divided in a lower part 2, into which reaches the cable 3 of the electric generator, and an upper part 5, connected with a joint or in any other way, for increasing the capacity and for being removed, after the solidification of the ionic solution of the medicament in a low temperature ambient, so as to form a head for the emission of ions between 0.degree. and -5.degree. C., and to be kept into contact, manu
