6 Claims. (01.128-417) This invention relates to electrical therapeutic pads such as are used in connection with electrical therapeutic apparatus, one type of which is illustrated'in my Patents No. 1,268,545, June I 4,. 1918,or No. 1,587,505, June 8, 1926, or No.
1,925,370, September 5, 1933. v i
The pads used in connection with such apparatus are sometimes constructed with an envelope member of rubber or other insulating ma- 10 terial which is provided with a pad-receiving pocket, and a pad member which fills the pocket and has one face exposed for contact with the part to be treated. For some medical treatments a pad member of absorbent material is consid- 15 ered to be best while for other treatments a pad member having a metallic surface is deemed more beneficial. .Both forms of pad are usually provided with a wiring terminal to which the circuit wire from the electrical therapeutic appag ratus maybe attached. In the case of a pad having an absorbent pad member it is customary to moisten the absorbent pad member before it is applied to the part to be treated, the moisteninglof the pad serving to decrease the electrical g resistance and form'a better contact.
:"WQneobjectof the present invention is to provide an improved form of pad which is constructed so that it will --fit and have proper contact with curved surfaces such as those presented by 30 apersons arm, leg, shoulder, etc. as well as with flat surfaces. c -This object is accomplished by making the pad in sections which are flexibly connected together, each section presenting a pad member 35 which is enclosed, except at its operative surface, within an envelope of rubber or similar material, each section also having a circuitcon nection by which the necessary current may be supplied to the pad section. 40 i In orderto give an understanding of the invention I have illustrated in the'drawing some selected embodiments thereof which will now be described after which the novel features will be pointed outin the appended claims. 45 1 Fig. 1 is a view of a pad embodying my inventiomi T V Fig. 2 is a section on the line 2-2, Fig. 1; Fig. 3 is asection on the line 3- -3, Fig. 1; Fig. 4 is a sectional view also on the line 3-3, 50 Fig. l but showing the pad as applied to a roundedisurface such as that presented by ones arm or shoulder; fiFig. '5 is a perspective view of the'rubber envelope showing the pockets in whichthe pad members are're'ceived;
Fig. 6 is a perspective view of one of the contact members to which the electrodes are secured;
Fig. '7 is a fragmentary perspective view of one of the electrodes; 5
Fig. 8 is a fragmentary perspective view illustrating a diiferent form of pad member from that shown in Figs. 2 to 4.
The pad is indicated generally at I. It comprises in its construction an envelope member 2 10"- of insulating material, preferably of soft rubber, which is formed with a plurality of padreceiving pockets 3 as shown best in Fig. 5, and a pad member formed with a. plurality of pad sections adapted to be received in the pockets 3, each section having a face which is exposed and is adapted to be placed in contact with the part to be treated.
Thezpad member may be constructed with a fibrous and absorbent face or may be constructed with a metallic face, depending upon the character of the treatment to be given to the patient.
The envelope member 2 will preferably be molded to present the sections I0, each section forming one of the pad-receiving pockets 3. The adjacent sides of the adjacent sections II] are connected by a web portion II and the envelope is provided with a peripheral flange 9 extending entirely around it, said flange and the portions H occupying substantially the same plane.
As stated above the pad is made in sections which are received in the pockets 3. In Figs.
2, 3 and 4, I have shown a pad member, indicated generally at 6, which is constructed of absorbent material and which is made in a plurality of pad sections 7 that are located in the pockets 3. In Fig. 8,I have shown a pad section 24 having a metallic surfaceand which is of a size to fit into one of the pockets 3.
Referring now to the form of the invention shown in Figs. 2 to 4 in which the pad member is formedof'the separate pad sections 1 flexibly connected together, each pad section is made of some suitable absorbent material I3, such for instance as asbestos, and is covered by a casing or covering I2 of some suitable fabric. The separate sections 1 of the pad are flexibly connected by the portions M of the fabric covering l2 and are thus integrally connected.
Each pad section I has associated with it an electrode to which the circuit wire is connected. These electrodes are indicated at l5 and are in the natureof, plates that are situated between each pad section 1 and the rear wall of the corresponding pocket 3 of the envelope or padholding member 2.
The electrode plates [5 are preferably of a size corresponding to the pad sections. Each electrode I5 is formed with a wiring terminal H5 in the form of a finger or projection which conveniently can be struck up from the electrode as shown in Fig. '7. These wiring terminals I6 extend through openings l1 formed in the back wall of the envelope 2 and are constructed to have the circuit wires attached thereto in some suitable way. In the construction shown the outer wall of each pocket 3 has a contact plate I! molded therein, said plate having a surface exposed on the outside of the envelope or pad-holding member 2.
The contact plate herein illustrated is made of a strip of metal bent into the U shape as shown in Fig. 6 and provided with an opening I8. These contact plates are molded in the wall of the envelope 2 in such a way that one leg IQ of each plate is exposed on the outer surface of the envelope 2.
The wiring terminal projections l6 extend through the openings l8 and are bent over against the exposed face of the contact member H.
The contact plates I! are all connected through the medium of a wire connection 20 and one of the contact plates (the central contact plate in Fig. 1) is provided with a terminal 2| to which the circuit Wire may be connected in any suitable way. A convenient way of electrically connecting the wire connection 20 to the contact plates I! and the wiring terminals I6 is by stripping all the insulation from the wire 20 at intervals as shown at 22 and then placing the bared portions of the wire against and in contact with the contact plate H and bending the wiring terminal I6 over the bared wire and into engagement with the contact plate. To make a permanent connection the bared portions 22 of the wire may be soldered to the contact plate and the wiring terminal. The contactplates, and the electrodes are thus all connected in multiple.
. The sectional pad member 6 is readily removable from the rubber envelope 2 and in using the device this pad member will be removed from the envelope and moistened to the, desired degree, after which it will be replaced in the envelope as shown in the drawing. The pad is then placed on the part to be treated with the surface 8 of the pad member in engagement with the flesh, and the current is supplied to the padthrough an electrical connection connected to the terminal 2|. If the pad is applied to a flat portion of the body it Will have the shape shown in Fig. 3. If the arm or the shoulder or some other portion of the body having a roundedcontour is to be treated then the pad when placed thereon will assume the position shown in Fig. 4 wherein 23 indicates the portion of the body to which the pad is applied. When the pad is thus applied to a rounded portion of the body it will assume the curved shape shown in Fig. 4 and thus the operative surfaces of the pad will conform accurately to the rounded surface to which it is applied.
It will be noted that the peripheral flange 9 is in the same plane as the connecting portions H between the sections and hence when the pad is applied to a rounded surface as shown in Fig. 4 there will be no buckling of the flange. The wire connection 20 is made so that the portion of the Wire connecting adjacent contact plates is of sufficient length to permit the separation of the sections of the pad when the latter is applied to a rounded surface.
For some electrical treatments it is desirable to use a pad having a metallic surface. In such case a pad constructed as shown in Fig. 8 may be employed, said figure showing one section only of the pad. This pad section is shown as formed with a body portion 25 of insulating material and a metallic sheath 26 covering the body and forming the exterior surface. This pad section is of a size to fit one of the pockets 3 and it will be understood that there will be a similar pad section in each of the pockets 3. These pad sections may be made so that they will fit the walls of the pocket 3 tightly enough to be retained therein by the frictional contact with the walls. In this embodiment the engagement of the metallic surfaced pad with the electrode l5 will furnish the necessary contact to carry the electric current to the operative surface of the pad and thus to the patient.
The different metallic pad sections 24 may, if desired, be flexibly connected together in some suitable Way, or said pad sections may be entirely independent from each other. In either event, however, the fact that the pad member is made in sections and the sections are located in the flexibly-connected pockets 3, produces a flexible pad which can be easily bent to conform to curved surfaces.
If, for any reason, it is necessary to renew one of the electrodes l5, this can be readily done by melting the solder by which the wire and the wiring terminal is connected to the contact plate and then bending the wire terminal up into a right angular position so that it can be Withdrawn from the opening I8.
The sectional pad herein shown may be considered as having a cellular structure, each section of the cover being in the form of a cell containing the corresponding pad section.
