Application Mayv 16,

13 Claims.

This invention relates to therapeutic appliances. More 1 specifically, it has reference to therapeutic appliances where high frequency electric current is utilized as a curative medium as, for example, in transverse cerebral diathermy. Broadly considered, my invention is directed toward securing more effective curative results in treatments of the kind referred to than possible of attainment. with apparatus and appliances heretofore designedV for the purpose, with attendant preclusion of injury to the skin of the patient at the regions where the electric current enters and leaves the part or parts of the body undergoing treatment, and with assurance of minimum discomfort toi the patient.`

The foregoing desiderata I realize, as hereinafter more fully dis-closed, through provision of electrodes embodying multiple plate components of relatively large at areas which have the capacity to adapt themselves readily to the contour of vthe part or parts of the body to which they are applied, so that the entire surfaces of said electrode components contact intimately with the skin `oi? the patient. Obviously, under these conditions, arcing cannot take place to burn the skin, with the further advantage of a corresponding decrease in electrical resistance so that lthe maximum` current at a prescribed voltage is permitted to pass through the tissues. Another object of my invention is to` preclude irritation of major nerves in the localities where contact is made withV the` skin-for example, the supra orbital nerve incident to transverse cerebral 4diathermy treatments. This further desiderata I'realize, also as more fully disclosed hereinafter, by `so arranging the components of the multiple electrodesj that the special Y intervals separating them correspond in position and conguration to the, nerve jor nerves which are to "40 be avoided. f Y 'Y Still other importantobjects and advantages of this inventionwill be'manifest from the detailed "description following of the drawings, wherein Figs. I and II respectively are views of opposite sides of a therapeutic appliance conveniently incorporating the presentY improvele A ments.,`

Figs. III and IV lare detail sectional views on a largerscale taken as indicated respectively by the arrows III-III and IV`IV in Figs. I and II;

and n Fig. V is an illustration showing how the appliance is used.`

As herein delineated, my novel therapeutic l55 appliance is in the form adapted for use in 1935, serial No. 21,707

transverse cerebral diathermy treatments and, accordingly comprises a band I adapted to be secured about the head` of the patient. In the present instance, the band I consists of two straps 2 and il constructed of leather or other 5 suitable flexible material, the strap 2 being fitted lat its opposite ends withbu'ckles i and 5, and the strap 3 formed at its opposite end with perforated tongues Ii and l tofrespectivelyvengage said buckles. At the middle, the strap 2 has l0 a widened portion 8, which, for a reason later on explained, is offset upwardly somewhat in respect to the longitudinal through the narrower buckle-carrying ends 9 and II) of saidstrap.

Cemented or otherwise permanently attached to the inner face of the widened center portion 8 of the strap 2 is an elliptic pad I I of relatively soft rubber or the like which is concaved somewhat both longitudinally and transversely, and which decreases in thickness from the center symmetrically toward opposite ends thereof as shown in Figs. III and IV. Cemented in turn to the exposed face of the pad II are four plate components I2, I3, It, and I5 oiV a multiple electrode which are fashioned from thin, fiat` springy sheet metal, such as German silver or the like, high in electric conductivity. As shown, the end electrode components I2 and VI3 and the upper and lower center electrodecomponents I4 and I5 are symmetrically disposedrelative to each other and to the center of the pad il, and together aggregate the Varea of the pad except for narrow outwardly-curving complementary spacing intervals I6, and a straight longitudinal connecting interval Il which extends crosswise between said curving intervals. Imbedded in the pad II is a cruciform connector I also Vof pliable sheetmaterial high in electric conductivity whereof the ends are soldered or welded fast to the vbacks of the plate electrode components I2-I5 at the centers of the latter. The connector I8 is in turn welded or otherwise secured at its center to a terminal stud I9 which `extends rearwardly through the strap 2 and which terminates in a projecting rounded head 2B. Bearing against the back of the pad II is a relatively light flat sheet metal backing spring 2I which corresponds in configuration with the upper and lower center electrode components I4 Y' and I5 and which is centrally secured between the strap 2 and a circumferential flange 22 on the stud I9 as shown in Figs. III and IV. The illustrated stud I9 is of the snap fastener type adapted to receive a button v23 forming` the ter- ,55

minal of a flexible conductor cord 24 of negligible resistance, see Fig. I.

The strap 3 also has a widened center portion 25, which, however, lies in a direct line with the strap ends 6 and 'l and the buckle supporting ends 9 and ID of the strap 2. To the enlarged portion 25 of the strap 3 is secured a soft rubber pad 26 which is identical in size and shape with the pad H on the strap 2, and which moreover on its exposed face carries flat springy plate electrode components 21, 28, 29, and 30 corresponding to the electrode components |2-I5 of said strap 2. Here also, a cruciform connector 3| of sheet metal with the ends of its arms soldered or welded respectively to the electrode components 21-30, is centrally engaged with a stud 32 extending rearwardly through the strap 3 and terminating in a head 33 to receive a snap button terminal 3l# on a second flexible conductor 35 of negligible resistance. Similarly also, the pad 26 is backed by a vertically bowed backing spring 36 of sheet metal having a configuration and area corresponding substantially to that of the two center electrode components 29 and 36.

In use, the band I is secured about the head as shown in Fig.L V with the pad Il placed against the forehead, and the pad 26 against the back of the head. As the band I is drawn up by means of the buckles 4 and 5, the soft rubber pads Il and 26 yield readily to compression, and thereby permit the flat springy plate electrodes to adapt themselves to the contour of the head. Incidentally, the plate springs 2| and 36 also yield to slight compression with assurance of full surface bearing of the electrode components I2-I5 of the pad lli and the electrode components 21-36 of the pad 26 upon corresponding areas of the patients skin and hair.

With the band in place as just explained, the conductors 24 and 35 are connected to a suitable source of high frequency electric current, Which current passes through the head of the patient between the multiple plate electrodes of the front and rear pads II and 26 respectively. Through maintenance of effective, extensive and intimate contact of the multiple plate electrodes with the skin and hair of the patient by the combined action of the resilient pads H and 26 and the augmentative pressure of the backing springs 2| and 36, the parts of the appliance are substantially eliminated as a resistance factor to the flow of the electric current, the only impedance to be overcome being that offered by the bones and the tissues of the head. Accordingly, the maximum flow of current at a given voltage (which may differ in degree in accordance with the constitution of the subject and the nature of the ailment which is to be cured or improved) is available for the treatment. A further advantage resulting from the eilicient and extensive surface contact of the multiple electrodes is that arcing of the electric current is preeluded and injury prevented to the skin of the subject by burning as often happened heretofore. As a consequence, currents at higher voltages can be employed in therapeutic treatments with perfect safety if the nature of the ailment should require it. With the multiple electrode plate components proportioned and arranged as shown, and the band l properly placed on the head, the outwardly curving interspaces between the center and end plates of the frontal pad will coincide in position with the supra orbital nerve which is thus protected against the influence of the electric current, with avoidance of discomfort and/or pain to the patient. The upward offsetting of the widened center portion of the strap 2 is advantageous in that it disposes the buckles 4 and the rear strap 3 to a level where a more effective hold can be maintained on the head, without however detracting from the efficiency of the contact of the frontal multiple electrode with the forehead.

The effect of the electric current is of course to heat or Warm the bones and tissues through which it passes, thereby stimulating the action of the nutrient vessels and at the same time inducing increased activity in non-functioning or mal-functioning portions of the brain. The therapeutic appliance of my invention is especially advantageous in cases of internal scar tissue to promote nutrition; essential hypertension; chronic inflammation of the brain; secondary symptoms of skull fracture; as well as in the treatment of kindred ailments. It is a recognized fact that hyperemia caused by heating of the skull bones results in increased activity in the head region even in cases of brain destruction.

It is to be understood that my new therapeutic appliance is not limited to the details of construction and arrangement herein shown by way of example, since these may be considerably varied within the scope of the appended claims without departing from the spirit of my invention.
