Patented .rely 22, 194i UNITED STATES PATENT OFFICE ELECTRODE MEANS FOR USE IN SHORT- WAVE DIATHERMY TREATMENT Cecil J. Birtcher, Alhambra, Calif. Application May 6, 1940, Serialo. 333,508
4 Claims. (Qi. 12S-413) y l ber removably secured to the treatment face of This invention is concerned with so-called "short-Wave applicators, for application of short-Wave energy to a patient through the generation of a heating effect Within the patients body by means of capacity coupled short-Wave electrical energy. The invention is primarily concerned with a specific form of applicator which I have designated a caput applicator, for treatment of the head portion of a patient.
The application of short-Wave energy in diathermy treatment requires that the patients body portion be electrically insulated from the electrodes which establish the high-frequency treatment field, and in the treatment of localized zones in the head considerable difficulty has heretofore been experienced in securing the proper placement of the treatment electrodes With respect to treatment efliciency and the comfort of the patient. For the most part rather large electrodes or applicators have been employed, these electrodes being strapped into place, Which failed to secure the desired localization of the treatment and resulted also in considerable discomfort to the patient.
One of the particular objects of this invention is to provide a diathermy applicator of the type described, provided with a, plurality of treatment electrodes mounted on a common support adapted to be manually supported by the patient, such electrodes being eXibly secured to the support through the agency of conductor means which are so fabricated as to be readily bendable manually and to retain the form in which they are bent during the application of the treatment energy, Wherefore the several electrodes may be comfortably positioned with respect to the desired localized portions of the patients head and maintained in such position by the patient himself, making it possible for the patient to remove the applicator from the treatment position at any time should the treatment become uncomfortably strong and to return the applicator to the original treatment position at will.
A further object of the invention is to provide a caput diathermy applicator of the type above set forth in which the individual 4electrodes making up the device are of a deformable nature wherefore they may be deformed to comfortably conform to the surface outline of the localized zone under treatment, and to retain such deformation.
A further object of the invention is to provide a diathermy applicator of the type set forth in Whichv the respective treatment electrodes are provided With a disposable absorbent pad memsuch electrodes for contact with the area to be treated. A
Other objects of the invention Will be set forth in the following description of certain preferred embodiments thereof, or will be apparent from such description.
The accompanying drawings illustrate such embodiments and referring thereto:
Fig. 1 illustrates the caput applicator of this invention with its plurality of electrodes arranged for direct treatment of the frontal and antrum sinuses of a patient;
Fig. 2 is a vertical section through one of the treatment electrodes, such as may be taken along the line generally indicated at 2--2 in Fig. l;
Fig. 3 is a partly broken away View of one of the disposable absorbent pads which may be used onone of the electrodes according to this inven 2Q tion, looking in the direction indicated by the arrows 3--3 inFig. 2; y Fig. 4 is a transverse section thereof as taken on line 4--4 in Fig. 3;
Fig. 5 is a longitudinal (vertical) section of the support means for the plurality of electrodes;
Fig. 6 is a vertical section thereof taken on line 6 6 therein;
Fig. 7 is a view corresponding to Fig. 6, showingan alternative form of the device; and
Fig. 8 is a vertical section thereof taken on line 8-8 in Fig. 7.
Referring particularly to Figs. 1 and 2, the devicemay comprise a handle member l of Bakelite or comparable non-conductive material, carrying a junction 2 from Which a plurality of conductors 3, 4 and 5 branch outwardly, the respecto maintain any curvature to which they may be bent, yet flexible enough to be readily bent manually. Specifically, I have found that No. 9 B. & S. gauge copper or copper-beryllium alloy wire is entirely satisfactory for the purpose.4 The electrode members E, and 8 may comprise a atsheet electrode li, preferably of copper and of such-thickness as to be manually deformable and yet of such rigidity as to retain such deformed condition, to which a metallic boss I2 is attached preferably adjacent the central portion, said boss conveniently extending through an .opening in electrode ll and being peened or riveted over at the opposite side as at I3. The
g boss i2 is bored axially to receive the end of the conductor 4, for example, which may be soldered in place, and is exteriorly threaded to receive a threaded insulated sleeve i4 which surrounds the rubber or other suitable insulating envelopV l 5 for the conductor 4. The electrode sheet Il is suitably encased within an insulated envelop, which may comprise two sheets of sponge rubber or the like IS and Il disposed at the two faces of the sheet ll and projecting marginally thereof. The two sheets I6 and I1 are inter-secured at their adjoining marginal portions, as at I8, and a band of rubber or the like is preferably provided peripherally of the sheets I6 and I'l as at I9 and the rubber structure is preferably then vulcanized into an integral unit to completely encase the electrode sheet H. In order to Vpre- Vvent inadvertent contact by the patient with the metallic boss I2, I preferably provide la thin insulated washer 2| about the boss l2 and against the rearward face of the sponge rubber sheet Il, against which the forward end of the insulating sleeve I4 may be caused to bear when threaded upon the boss I2.
YThe mounting of the respective conductors 3, 4 and-5 within the junction 2 may conform to the showing in Figs. 5 and 6, and referring thereto the handle member i is indicated as being tubular in form and providedwith an internally threaded upper Vend 22 adapted to receive the threaded end 23 of a metallic terminal 24 secured within an insulating housing 25 which may be dened by two mating hemispherical shell member-s 26 and 2l. As shown further in Fig. 1, a current supply line 28 may be-brought through a suitable opening V29 in the housing 25 and is electrically secured to the terminal 24 as at '3L The laterally extending conductors 4 and 5 may be brought through the'housing 25 in circumferentiallyspaced relation to the conductor 28 Yas at 32 and 33, and are `electrically intersecured with the terminal 24 as at'34'and35. 'Ihevconductor '3 `may be brought through a suitable opening 35 in the upper shell 26 of the housing 25, and iselectrically intersecured with theterminal 24 as at 3l. The terminal 24 may be secured to the upper shell member 25 through the'agency of a screw 33, and the mating upper and lower shell members 26 and`21 may be'ixed in their mating relation Awhen the handle l is rotated to take up on the threaded portion 23 of the terminal 24, drawing fthe upper shell 26 downwardly'upon they lower shell 21.`
' The above construction provides for positive attachment-,ofthe bendable conductors 3'4'and 35 to the terminal 24, which is rigidly 'secured to the handle l, and in View of` the fact that the exterior insulating covering for the respecably extended through the respective 'openings inthe housing 25,some cushioning effect is secured duringy any bending operation on the conductors'with respectto the `application of any strong bend 'fat the position of attachment to the terminah wherefore a long life of the conductor under repeated bendings is secured. 'In
other words, the respective conductors are lrmly removed from such centrally'disposed terminal through the agency of the housing 25. ,Y
In Fig. v1 the caput electrode is'specifi'cally illustrated `as positioned Vfor Vtreatment of the frontal sinus through the electrode and for treatment of the yantrums through 4side electrode members 'l and 8. It will be appreciated that the device may be employed to treat only the antrums by the simple expedient of bending the conductor 3 upwardly, as indicated by dot-dash lines at 3 to carry the electrode 6 to a position 6 spaced from the patients forehead. Similarly the lateral electrodes 1 and 8 may be positioned about the throat for application of the short wave energy to the tonsil regions, if desired. In this particular form of the applicator, all of the electrodes are connected to a common pole or lead from the short wave power supply which is indicated diagrammatically at 4|, and it will be appreciated that the other side of the short wave power supply may be connected to an insulated electrode 42 which may be placed at the back of the patients head, against the shoulder blades or in any other suitable position to accentuate the condenser eld. The use of the electrode 42 is not essential inasmuch as the body capacity of the patient maybe relied upon to secure the desiredcapacitative coupling.
' It will further be appreciated that it may at times be desirable to more effectively accentuate the electrostatic eld at the position of the electrodes, in specific treatment problems, wherefore it is within the contemplation of this invention that certain of the electrode members 6, 'l and 8 will be connected to one side of the short wave power supplymeans and others will be connected to the opposite side of the short wave power supply means. For this purpose I have illustrated in Figs. 7 and 8 a form of junction which may b-e employed to connect the latthrough a suitable opening in the lower shell tive* electrodes such Vas shown at l5 is preferv attached to the interiorrof the supporting juncf j tj'ionfstructure asto the centrally disposed terminal* 24, and aref'supported Yat positionsV outwardly 45a of alhousing 4'5, as at 46 and electrically connected to the terminal 44. The conductors 4 and 5 arev brought through the sides of the housing45 as at 4i and 48 and electrically Yconnected to the terminal. The conductor 3 communicatingwith the electrode is provided with separate connection to the other side of the short wave power supply in Aany suitable manner as through the agency of a metallic connector ring 5I extending about an insulating sleeve 52 mounted on the upper end ofthe terminal y44 and bearing against a similarly mounted connector ring 53 which is'electrically connected to the other side of the short wave 'power supply through a flexible conduit '54 which may be-vd-esignated as supply line B. The respective shells-'45a and 45h may be interse'cure'd 'as 'described in connection withFigs. 5 'andf and 'the upper shell 45h may be rigidly connected to the terminal 44 through-the agency-'of a screw 55 corresponding Ytoithe screw 3B, :which .may 'also be employed to rigidly cljampj the 'connector rings 5l and 53 in longitudinalengagement.' The connection )of the twoV lateral electrode means `l and *Sto one side 'of the lenergysource and 'the aai-9,93%

thermy treatment and the provison of such pads contributes materially to the proper function of the structure. The pad structure may comprise an absorbent layer El at its forward face, adhesively secured to a backing layer E2 which is preferably shaped to conform to the outline Vof the electrode member to which it is to be applied. Attaching means for securing the absorbent layer to the electrode member are provided, such as rubber bands or the like 63 disposed at the rearward face of the backing layer 62 and held in position with respect thereto through the agency of an attachment layer 64 which may be adhesively secured to the backing layer 62. The attachment layer G4 is preferably recessed in its plane at the position of the ends of the bands 63, as at 65 to minimize the tendency for the attachment layer to be pulled away from the backing layer 62 when the rubber bands are stretched about the electrode structure, as illustrated in Figs. 1 and 2. Alternative forms of absorbent pads Will occur to those skilled in the art and I do not choose to be limited to the specic structure thereof herein delineated. Other modications of the specific electrode assembly will also occur to those skilled in the art and the illustrated embodiments are to be taken by way of example only.
