151103 013 THE THERAPEUTIC ELECTRODE.
Application filed September 1821. Serial No. 499,595.
To, aZZ who-m it may conce n:
Be, it known that I, AARON J. TYLER, a citizen of the United States, residing at Rochester, in the county of Monroe and 5 State of New York, have invented certain newand useful Improvements in Therapeutic Electrodes, of which the following is a isl pecification. V i *hisinvention relatesto appliances for 10 the therapeutic application of the electric current, and more particularly to an electrode in the form of a metallic mat adapted to be applied to the part of the body to be treated. I
One of the primaryv objectsvofthe present inventioncis to providea mat which, notwithstanding its necessarily metallic nature,
Will be so constructed as to conform closely to the contour of the part of the body to be treated and against which itis' applied. Considerable inconvenience and sometimes injury results from the use of electrodes of the usual type inasmuch as itany part of the electrode is placed close to the body Without being, in actual contact therewith, a spark gap will be produced, and the treatment becomes painful both during the period of application of the electrodeand .also subsequently, if the flesh is blistered, Therefore the present invention contemplates the provision of an electrode in the form or a fieXible metallic mat adapted to be laid in close contact with the part ofthe body to be treated and to conform closely to the contour of such part so that there will be no likelihood of some one portion oranother of the mat becoming displaced so as to be spaced from the body and form a 'sparkgap.
object of the invention is to pro- Another vide, in connection with a mat oi the type above outlined, novel means whereby a cona doctor terminal may be readily electrically connected with the mat and without any likelihood of the weight of the conductor or a pull thereon causing displacement of the mat.
In th accompanying "drawings Figure 1 is a perspective view illustrating the mat embodying the invention in use; Figure. 2 is a plan View in detail of the mat;
V Figure 3 is a perspective view illustrating the connection provided for the conductor terminal equally as well be made inmuch smaller,
sizes for application to other partsofthe anatomy. The mat 1 in any event comprises a sheet of metallic mesh consisting of small interlocked rings or. links, and it will be understood, as the dirnensionis lot the mat may in general be varied, *so likewise may the size ofthe mesh bevaried to suit conditions. Likewiseiariy metal found suitable for the purpos may be employed so long as it is a good conductor of electricity, and itvvill no doubt be pifeferalile to make'use of a metal which is non-corroding. I a
' The mat 1 is marginally bound as indi cated by the numeral 8, by tape, a cloth hem, or in any other manner found desirable, and also material may be employed for this purpose other than cloth. In theillustrated embodiment of the invention there is shown a mat which is'of dimensions and marginal q contour adapting it for general application to the "major parts of the body as for example to the back or to the limbs, and in order that the mat may be securely held in place after it has been arranged in contact with the portion of the body to be treated,'attaching tapes may be securedi'to the margin of the mat at 'suitable points. In the present instance, tapesA-V will be: se-' cured to the upper corners of the mat, tape 5 to the lower corners, and other tapes 6 to the opposite sides: of the matvat any point suitably spaced betweentthe attached ends of the tapes 4 and 5. In thisarrangement, the tapes 5 and 6 maybe passed and r tied about the body atand above the-waist line, assuming that themat is to be ap plied to the back in about the pos tion lllustrated in Figure 1. ofthe drawingsyand the other tapes 4E may be led upwardly and over the shoulders and tied at their free ends so as to support the mat against downward displacement.
At this point it will be evident that the mat, being of mesh material will, when a plied to any part of the anatomy, close y conform to the. contour thereof automatically, and without the "necessity of a careful arrangement of the various portions of its area. Consequently in making use of the mat embodying the invention the patient being subjected to treatment, is not liable to suffer any inconvenience or injury such as is occasioned in the use of the ordinary'electrode having an inflexible contact surface, Also 1t Wlll be evident that, because of the peculiar character of the contact surface of the mat embodying the invention, the surface will conform closely to the contour of any'part of the body upon which the mat is laid, the mesh accommodating itself automatically to depressed portions of the body surface as Well as to raised portions thereof.
The mat will of course be employed in connection with an electrical conductor usually k the clip 8 of the conductor cord 7 may be electrically connected with the mat without likelihood of the weight of the cord or any pull exerted thereon causing displacement of the mat to space any portion of the l area thereof from the surface of the body.
The means referred to comprises two members indicated one by the numeral .9 and the other by the numeral 10. The member '9 constitutes a bearing member and is pref- 40 erably in the nature ofa flat strip of sheet metal which is disposed against the inner surface of the mat and is designed to rest snugly against'the surface of the body when the mat is laid over the part tobe treated.
The member 10 constitutes a connecting member and is preferably formed from "sheet metaland comprises a flatsided body ll provided with a shank portion 12 offset with relation to the body 11 preferably in a 750' plane substantially parallel thereto. by an intervening bend 13. A rivet or pivot pin or similar connecting or fastening element 14 is secured through the shank portion 12 ,of the member 10 and through one end of 5 the member 9, passing also through the'mat 1, and this element 14- serves to pivotally connect the members 9 and 10 to the mat so that these members may be swung in lunison' in any desired direction about the element 14 as a center. By reason of the bend 13 in the'shank 12 of the member 10, the body 11 of the said member is spaced withrelation tothe mat 1 a sufficient distance. to permit of the ready application "of the clip 8 to the body 11 of the said member 10. The clip may be applied at the most convenient angle and it will be understood that after the mat has been applied and bound to the body, and the clip 8 of the conductor cord 7 is. attached to the body 11 of the member 10, the cord will assume a position of repose, and because of the pivotal connection of the member 10 with the mat, this member willswing about its pivot to accommodate itself to the position assumed by the cord. In like manner should thecord be displaced in any direction, thev member 10 will pivot upon theimat to assume a position permitting" of the changed position of the-cord and this without in any way lifting the mat from the body so as to space the same and cause the formation of a spark gap.
Having thus described the invention, what is claimed as new is: l l 1. A therapeutic electrode comprising a flexible contact member. a bearing member disposed against one surface of theconta'ct .member and adapted to'rest upon the surface of the body when the electrode is in use. a connecting member comprismg an at taching' shank portion disposed against the other surface of the contact member opp'o- 7 site one end of the bearing member. a pivot pin titted through the connecting member and contact memberand provldinc'for free independent adjustment of the said contact a and connecting members, the connecting member having a portion offset with relation to. its shank and ofsubstantially flat circular form adaptingit for the connection thereto. at various angles and in various positions, of a conductor terminal clip.
2. A therapeutic electrode comprising a flexible contact member. a piyotwpin sup-- ported upon the said member. and aconnecting member comprising an attaching shank portion pivotallv connected with the said pivot pin and resting flatup'on tlie surface of the flexible contactmemben the said shank portion having an upwardly inclined portion, and a portion of substantially fiat circular form supported at the upper end thereofand thereby spaced from the surface of the said flexible contact member.
In testimony whereof I affix my signature.
