' ELECTRODE Filed Sept. 12, 1951 //vv/v TOR= Camus Z0 Vi 859mm Patented Nov. 11, 1952 UNITED STATES PATENT OFFICE Application September 12, 1951, Serial No. 246,220 In Great Britain November 1, 1949 1 Claim.
This invention relates to apparatus for carrying out electro-therapeutic treatments, and has for its chief object to provide a device which will facilitate the treatment of injuries, rheumatism and other ailments by rhythmic muscular contractions in horses, the treatment being carried out by faradic currents. In electro-therapeutic treatments, such as those referred to above, it is necessary, of course, to complete the circuit for the faradic current. It is usual to use an applicator which is carried in the operators hand and moved about from place to place as required in order to carry out the desired treatment. In treating human beings, one electrode is strapped to, or held in place by the weight of, the body so that the circuit is completed through the body. The present invention is concerned with the fixed electrode, as distinct from the applicator, of such a system, and has for its chief object to provide a simple and very effective construction of the same for use in the treatment of horses.
The device according to the present invention is similar to a normal rugging roller for horses, but is characterised by the presence on the inside of the same of a mail or chain mail electrode adapted to extend down on either side of the horses spine, a plug or socket being carried on the outside, whereby a readily detachable electric connection may be made to the mail or chain mail, and a sheet of waterproof material being interposed between the mail or chain mail and the material of the roller.
Conveniently, the mail or chain mail electrodes on the two sides of the horses spine are separate from one another and are individually connected to the contacts of a plug or socket on the outside of the device.
In order that this invention may be the more clearly understood and readily carried into effeet, reference may be made to the accompanying drawings, which illustrate by way of example one convenient embodiment of the present invention, and in which:
Figure 1 is a transverse section through the complete device.
Figure 2 is an underplan of the upper part of the device showing the chain mail electrodes, and
Figure 3 is a side elevation of the same.
Referring now to the accompanying drawings, the device for carrying out electro-therapeutic treatments on horses therein illustrated i similar to the usual rugging roller for use on horses which normally comprises an upper canvas part H], which may be, say, eight inches wide, padded on the inside with padding II to lie on either side of the horses spine (not shown). According to the present invention the upper canvas part I is provided with two straps I2 on each side adapted to be buckled to buckles 13 on the girth canvas M which is provided with loop 15 to receive the free ends of the straps l2. The inside of the upper part is covered to within, say, three inches of its ends but right up to the edges at the sides with waterproof material l6. Arranged inside the waterproof material It and at the upper part thereof are two sheets of mail or chain mail I! which are adapted, when the device is in use, to extend, say, six and a half inches down on either side of the horses spine. The two mail or chain mail electrodes I! are preferably separate from one another, as shown, and are individually connected to the contacts of a plug or socket IS on the top of the upper canvas part [2 above the horses spine. The desired electrical connection to the mail or chain mail electrodes I1 is made to the said plug or socket l8 by means of an appropriate lead, the two electrodes being, of course, electrically connected together.
The device according to the present invention is just as simple to put on a horse as an ordinary rugging roller, and is very eifective in carrying out electro-therapeutic treatments of the kind above set forth, the plug and socket connection to the mail or chain mail electrodes on the horses back rendering it a very simple matter to detach the lead immediately so as to leave the horse free if this should be necessary for any purpose.
A device for carrying out electro-therapeutic treatments of injuries, rheumatism and other ailments by rhythmic muscular contractions in horses, comprising a sheet of flexible material, such as canvas, adapted to lie over the horses spine, strap means for strapping said sheet of flexible material about the horses body, at least one sheet of waterproof material covering substantially the whole of the inside surface of said flexible material and secured thereto, at least one mail or chain-mail electrode attached to the inside of the device, padding between said waterproof material and said flexible material on either side of the mid-central line of the device to press said mail or chain-mail electrode into firm contact with the horses body on either side of the spine when the device is in use, and a readily detachable connection on the outside of said sheet of flexible material electrically connected to said mail or chain-mail electrode.
