UNITE sir-s ERWIN LAST, or VIENNA, AUSTRIA.

Application filed December 18,

y The application of electrodes to parts of the human body of irregular configuration,

more particularly the face, nose, the chin and so on meets with difficulties because the rigid lead electrodes heretofore used cannot be made to fit nicely the curvatures of the various parts of the face. Owing to the imperfect contacts injury to the skin could not be reliably avoided, more particularly in the diathermic treatment where comparatively considerable currentv intensities are resorted to. It has been attempted to avoid these drawbacks by using tin foil as the material for making the electrodes. While tin foil has the pliability required for nicely fitting the configuration of the various parts of the face, it is difficult to be brought into and held in. proper positions owing toits lack of mechanical strength, nor can it be used often, but the electrodes must be replaced by fresh ones after a comparativelyshort time.

The object of my invention is to provide an electrode which although consisting of.

metal foil, which is very suitable for the present purpose, may be used for a comparatively long time, at least with one and the same patient. With this object in View my invention consists of an electrically nonrconductive carrier comprising a foreheadstrip, a nose strip and a chin strip closely fitting the face and an electrically conductive lining on the side of such carrier next to the face and means for electrically connecting such lining with a source of current.

In the' annexed drawing I have shown by Way of example, an electrode for the dia thermic treatment of the human face which is the part of the human bodyrichestin irregular curvatures. Fig. 1 is a front elevation of the electrode. 2 is a section of the same on the line II II Fig; 1. Figs- 3, 4, 5, 6 and 7 show the main parts of which the. carrier off the electrode is composed. -Fig. 8 illustrates the way in which the main parts of the electrode are connected with bands to prevent it from shifting AND PROCESS OFMAKING THE iezaseriai No, 76,165, and in Austria November 14, 192-5.

next to the face the carrier is provided. with e a lining 3 made of metal foil such as tin foil. The lining 3 is somewhat greater than the surface of the carrier to be lined; The parts of the lining projecting beyond the carrier are folded round the edge of the carrier onto the side of the latter remotestfrom the face of thepatient andzare secured there to the carrier by any suitable means say by stick- 1ng-plaster-strips 4. At any suitable point, for instance near the chin a tin foil patch .5

is secured to the side ofthe carrier remotest fromthe face of the patient and is in good electrical connection with .themetal foil lining 3, and serves for connecting the latter to the supply wire 6. 1

The improved electrode is used for diathermic treatment in thefollowing manner:

ToIthe .part of the body to'be treated is first applied a special ointment; then the electrode 1S brought into position' and fixedby during treatment. The source of electricity is con- 'nected on the one hand to the lining 3 of the electrode and on the other hand to a metal I part not shown brought into intimate contact part of the body of the pawith a suitable tient. The circuit is then closed and the current intensity is gradually increased. If the patient feels a prickingeven at a com- ;paratively low intensity of current then the electrode doesnotfit nicely at all points.

This is remedied by slightly lifting themetal foil ofi' the carrier and inserting be tween the two a filler or, backing of wad or a similar yielding substance as shown in Fig.

2 at 7. If no pricking is felt the current in tensity is increased to the maximum value determined for each individualcase. Owing to the strong carrier the improved electrode is sufiiciently firinto be used over and over again after it has beenv made tonicely the face of the patient to be treated.

Theiprocess. of making an electrode in accordance with'my' inventlon will now be described. j First of all three strips of a suitable fabric, preferably starched gauze in common use-for surgical purposes are used,

.each about 6 centimetres in width andeach comprising a suitable number of layers, say 9to12.

-Thefirst strip 10 Figs 3 and 4 extends from one ear across the forehead to the other ear and will be called hereinafter the fore head strip. The second strip 15 Figso and llO I Fig.

neighbourhood of the eyebrows and the hairs on the temple and't'he' hairy parts of the head are covered by a suitable cap,

shawl or the like. The patient is'seated on a chair having a head support and has his or her head inclined backwards. The three strips are then brought into position on the patients face in succession. Preferably the nosestrip 15 is the first and is so placed that it extends from ear to ear across the nose, an assistant holding the ends of the strip in the proper position. In order that i the strip may be in uniform contact with the face an oblique cut 16' and another cut 17 at right angles to the cut 16' is made in the strip on either side of and near the middle of th'e strip and the flaps 18 resulting therefrom are folded outwards along the dotted line 19 on the nose. Thereby the inner eye corners are left uncovered and at the same time the part of the strip covering the upper I part of the nose is strengthened and a strong projection extending to the forehead is formed which is required for forming a reliable connection with the forehead strip. Similarly by folding down the triangular flap 20 along the dotted line 21 the lower eye lid which was covered by the strip is uncovered. Besides" at the lower edge of the strip on bothsides' of the wings of the 'nosethe two cuts 22 are provided and the be modeled.

This-modeling is continued until the strip has set to such as extent as to retain unaltered the shape into which it hasbeeir brought. Now the forehead strip 10 is placed acrossthe forehead from one ear to'the other. For accommodating" the forehead cuts 1 1, 1-2 have As shown in Fig. 8 the" ends of" the nose strip 15 and the forehead strip 10 are placed theone above the; other near the ears and may be readily held in position by the The modeling of the forehead the same way" as the far that while the strips" modeling of the nose strip a layer of a thick between the nose strip 15 and the forehead Thencthe projection of the nose strip 10 is secured, and this connection may i be 'strengthen'e'd if desired, by a piece of gauze dipped into apaste of plaster of Paris. hen the forehead strip has suflicien-tly hardened under continuous rubbing and kneading, the chin strip25 Fig. 7 is brought into the position shown in Fig. 8 so that it extends from one ear to the other and may be held by the assistant. The chin strip is modeled to nicely fit the lower part of the face. The mouth is left uncovered, but if desired the upper lip may be covered by a small strip 8 of gauze dipped intopaste of plaster of Paris and'seeur'e'd to the nose strip. For firmly connecting the three str s which up to this moment had been belt in position by the assistant a strip of .starched gauze moistened in hot water is wound from one templeacross the chin to the other temple and back again, a thick paste of plaster of P'arisbeing interposed between the successive layersofstrips and strei'igthening the same. Similarly the strip is wound across the forehead for sufiicientlystrengthening this part too. lWherever two strips crossfieach other it is important to establish a firm connection between them. The electrode carrier which resembles a mask is then permitted to dry on the face of the patient, which requires about 20' to 25 minutes, whereupon the carrier is removed and finally dried for instance on a heated metal plate.

To the inside of the completely dried carrier an electrically conductive lining is applied which may consist of tin foil cemented thereto, or the electrical-1y conductive lining maybe applied by electrode-position or by atoinizing a fused metal or alloy. In any case the lining 3 must be applied with the greatest nicety any projecting points or folds and any holes being carefully avoided as they might result in. injury to the skin.

Irregularities in applying. tin foil may be and electrically connected to the lining and to the source. of electricity.

What I claim isz 1. In an electrode to be applied to the folded down on the outside of human face the combination of an electrically non-conductive carrier consisting of a forehead strip a nose strip and achin strip closely fitting the face and an electrically conductive lining on the side of such carrier next to the said part of the body and means for electrically connecting such lining with a source of electric current.

2. In a electrode to be applied to the human face the combination of an electrically non-conductive carrier'consisting of a forehead strip a nose strip and a chin strip closely fitting the face and'such strips being provided with cuts at the edges for permitting them to be curved, an electrically conductive lining on the side of such carrier next to the said part of the body and means for electrically connecting such lining with a source of electric current.

3. A process for making electrodes to be applied to the human body consisting in modeling a plurality of strips of fabric strips are in a plastic state, to the part of the human bod to be treated, connecting such strips by similar strips and permitting the Whole to set While they are on the part of the body to be treated, removing the structure built up of stripsifrom the part of the body, completely drying such structure and applying to one side of such structure an electrically conductive lining.
