Kamm Attorney, Agent, or Firm-l-lill, Sherman, Meroni, , Gross & Simpson 57 ABSTRACT A disposable electrode structure for operatively connecting electrical equipment to the surface of live skin of a patient, employing a self-contained electrical conductive material for affecting the connection, and cover means for protectively sealing said conductive material, readily removable from the electrode structure at time of use. 24 Claims, 4 Drawing Figures DISPOSABLE ELECTRODE BACKGROUND OF THE INVENTION With the development and common usage of various types of electrical and electronic equipment for measuring and/or monitoring human body functions and the like, the demand for a suitable, highly 'efficient electrode structure has progressively increased. While it has been demonstrated in the past that an electrode structure employing a suitable conductive material such as a conductive gel, would appear to be the most effective from an operational standpoint, the use of such conductive gels has resulted in additional problems, particularly in connection with preserving the usefulness of the gel over prolonged periods whereby the electrode structure will have a relatively long shelf life, i.e., from manufacture to actual usage. It has proved to be desirable to clean and slightly roughen skin surface at the point of connection of the electrode thereto. Likewise, as reuse of a medical or surgical structure will normally require cleaning, sterilization, etc., the utilization of a disposable type structure requires not only a highly efficient structure but one that is very inexpensive to manufacture and generally quite simple in construction. SUMMARY OF THE INVENTION The present invention therefore has as its principal object the production of a highly efficient electrode structure of the type involved, utilizing a conductive gel or other suitable material as the connecting medium and yet which is relatively simple and relatively inexpensive to manufacture whereby the same may be economically employed as a single use structure which is disposable following use. This is accomplished in this invention by employing a structure comprising a plurality of sheets of suitable material, certain of which are each provided with a layer or coating of adhesive which form the means for securing respective elements to one another permanently, or detachably, and for connection of the structure to the skin of the patient. The metallic electrical terminal is disposed for connection to such skin surface by means of a conduit in gel, carried on a pad disposed at such terminal. The conductive gel is protected, prior to use by a cover assembly which includes an annular spacing member encircling the pad and gel, a protective sheet for the skin-engageable adhesive, and a cover sheet, the assembly being cooperable with a portion of the electrode structure to form a sealed protective enclosure for the pad and gel, operative to prevent undesired deterioration thereof over relatively long periods of storage, etc., prior to usage. BRIEF DESCRIPTION OF THE DRAWINGS In the drawings, wherein like reference characters indicate like or corresponding parts: FIG. 1 is a transverse sectional view of a disposable electrode structure and its protective cover assembly, taken approximately on the line II of FIG 2; FIG. 2 is a bottom view of the structure as illustrated in FIG. 1; FIG. 3 is a sectional view similar to FIG. 1 of the electrode structure following removal of the protective cover assembly therefor; and FIG. 4 is a plan diagrammatic view illustrating respective steps of a method of making the electrode structure and its cover assembly. DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, 2 and 3, the reference numeral 1 indicates generally the electrode structure in accordance with the present invention while reference numeral 2 indicates generally the protective cover assembly adapted to be engaged therewith and subsequently stripped off at time of use. While other configurations may be suitable in specific applications, I have found that in general a circular configuration is preferable and the various components making up the electrode structure and the basic cover assembly structure are illustrated as being circular in configuration with the various components generally arranged on a common axis. THE ELECTRODE STRUCTURE Referring to FIGS. 2 and 3, the electrode structure 1 comprises a first sheet 3 of suitable material and generally circular in configuration. I have found that'a thin fibrous porous material is preferable. A very satisfactory material is that known as Micropore, a brand manufactured by Minnesota Mining & Mfg. Co. The sheet 3 is provided with an opening 4 therein, likewise illustrated as being of circular configuration, across which extends a second relatively impermeable sheet 5, likewise of circular configuration, of a size to completely cover the opening 4 and overlie the sheet 3 ad-' jacent the periphery of the opening 4, the sheet 5 having a layer 6 thereon of suitable adhesive by means of which the sheet 5 is firmly attached to the sheet 3. The sheet 5 preferably is fabricated from suitable plastics, a polyethylene-vinyl laminate being particularly suitable. The sheet 3 likewise provided with an adhesive coating 7 on the lower or outer face as viewed in FIG. 3 by means of which the structure may be secured to the skin of a patient, theadhesive being of the nontoxic type commercially procurable. Secured to the second sheet 5 is an electrical terminal, indicated generally by the numeral 8 which is illustratedas comprising an outer connector-member 9 and an inner conact member 10. The connector member 9 comprises a circular base portion 11 from which extends a hollow bulbous portion 12 while the inner member 10 comprises a similar circular base portion 13 from which extends a hollow shank or stem 14. The latter is inserted in the bulbous portion 12 and the free end crimped over during the mounting operation to rigidly clamp the two members in operative position with the stem 14 extending through the sheet 5 and the latter firmly secured between the base portions 11 and 13 of the respective members. Disposed in the opening 4 and overlying the base portion 13 of the member 10 is a circular porous pad 15, secured in operative position by means of the exposed adhesive on the sheet 5. The pad 15 may be constructed, for example, of a porous or foam-type plastic such as that used in plastic sponges and the like, the pad 15 having or containing a supply of a conductive gel 16. As illustrated in FIG. 3, the bulbous portion 8 of the member 9 forms one half of a connector structure, to which another cooperable connector member 17 may be engaged, whereby an electrical conductor or the like 18 may be connected to the terminal 8. In use, the electrode structure illustrated in FIG. 3 is applied after suitable cleaning or preparation, if any, of the skin surface, by pressing th structure down the the skin surface to bring the pad 15 in firm engagement with the skin surface, following which the peripheral portions of the structure are pressed firmly into engagement with the skin surface, whereby the adhesive layer 7 will firmly adhere to such surface and thereby effectively secure the electrode structure'thereto, with the pad 15 thus providing a good physical connection between the contact member of the terminal 8 and the skin surface while the gel 16 forms an efficient electrically conductive connection between such skin surface and the base portion 13 of the member 10. Following such mounting of the electrode structure, the connec-. tor member 17 may be engaged with the terminal 8 to operatively connect the conductor or line 18 to the electrode structure. PROTECTIVE COVER ASSEMBLY The protective cover assembly 2 is constructed to not only seal the pad and the gel 16 carried thereby, as well as protect the adhesive layer 7, but to prevent undesired contacting of the pad and thus possible squeezing forces on the pad, which might force the material 16 therefrom and thus possibly impair the operation of the structure at the time of use. In the embodiment of the invention illustrated, the cover assembly 2 cornprises a relatively impermeable sheet of material 19, preferably heavier and stiffer than the first sheet 3 of the electrode structure, for example, a suitable paper, the sheet 19 having substantially the same external diameter as the sheet 3 and provided with an opening 20 therein which, in the embodiment illustrated, is slightly smaller than the opening 4 in the sheet 3. Disposed at the exterior face of the sheet 19 is a spacing ring 21 of suitable material, for example, polyethylene, the ring, as illustrated, having an inner diameter which is less than the diameters of both openings 20 and 4 in the respective sheets 19 and 3, whereby the inner face of the ring 21 may be engaged with the adhesive layer 6 on the sheet 5 to provide an effective seal between the latter and the ring. At the same time, the inner diameter of the ring 21 is greater than the diameter of the pad 5, whereby the ring will not engage and compress the pad. Overlying the ring 21 is a cover sheet 22, illustrated as having a diameter intermediate the outer diameter of the ring 21 and the outer peripheral edge of the sheet 19, the sheet 22 having an adhesive layer 23 thereon by means of which the sheet is firmly secured to the adjacent face of the ring 21 and to the adjacent outer face of the sheet 19. The sheet 22 preferably is adapted to provide an effective seal for the gel 16 and conveniently may be fabricated from the same material as the sheet 5. Likewise, the sheet 22 preferably has a diameter sufficient to permit the effective engagement of the sheet 22 to the sheet 19 to form a unitary cover assembly. To provide further protection of this gel 16, a second pad 15', may be provided which is disposed in opposition to the pad 15 and secured to the cover assembly by the adhesive layer 23 as the sheet 22. This construction eliminates any possibility of the pad 15 and gel thereon coming in contact with the adhesive layer 23. It will be particularly noted that the pads 15, 15' and the material 16 contained thereon are, by this construction, effectively sealed against external contamination with the ring 21 and sheets 5 and 22 forming a substantially air-tight chamber in which the conductive material may be stored for relatively long periods of time without material deterioration. When it is desired to use the electrode structure, the protective sheet 19 is merely stripped from the sheet 3 carrying with it the spacing ring 21 as well as the cover sheet 23 and pad 15. In this connection, it will be noted that in the construction illustrated the ring 21 partially overlies the sheet 19 so that the adhesive layer 6 on the sheet 5 is not in contact with the entire area of the adjacent face of the ring 21, whereas the opposite face of the ring is in contact throughout its area with the adhesive of the cover sheet 22. In view thereof, as well as the fact that the ring is, in effect, partially gripped between the sheets 19 and 22, the ring 21 will readily separate from the sheet 5 instead of from the remainder of the cover assembly. To facilitate such stripping, the sheet 19 preferably has a radially extending cut 24 therein extending from the opening 20 to the periphery of the sheet to enable the sheet 19 to be readily grasped thereat for stripping. Likewise, if the sheet 19 does not have a smooth surface readily strippable from the adhesive 7, the sheet may be provided with suitable surface coating, for example, a suitable silicone of known type. A cleaning strip 25, having a rough outer surface may be mounted on the face of the core assembly for use as an abrading type cleaning member and may, for example, be formed from a synthetic rubber material. MANUFACTURE OF THE STRUCTURE A preferred method of manufacture of the structure above-described is illustrated in FIG. 4 which depicts successive steps in such manufacture with alternate steps II being illustrated. The first step, as illustrated at I, may be the forming of an opening 4 in an adhesive coated strip of stock S from which the sheet 3 is to be eventually produced. The circular sheet 5, following cutting from suitable adhesive coated sheet stock is then disposed over the opening 4, as illustrated at II, and pressed into firm contact therewith whereby the adhesive coating on the sheet 5 will firmly secure the latter to the strip S. The terminal 8 may then be applied to the sheet 5 in any suitable manner in accordance with the techniques commonly employed in connection with such type of structure. If desired the terminal 8 may be first mounted on the sheet I and then the latter secured to the stock S'as illustrated at IIIT. IIIB illustrates the assembly at IIIT but from the reverse side of the strip S and at IV the previously formed sheet 19 with the cut 24 therein is disposed in operative position and firmly mounted by means of the adhesive layer 7 to the strip S. At V this ring 21 is applied, engaging the adhesive 6 of the sheet 5. At VI, the pad 15 is disposed in operative position and firmly engaged with the adhesive layer 6. The pad 5 is then impregnated with the conductive material 16 at VII, followed by the placement of the pad 15. If desired this gel may be disposed with the pad 15. The cover sheet 22, following previous formation from adhesive coated stock is applied in operative position, as illustrated at Vlll, and firmly adhesively connected with the adjacent face of the ring 21 and outer surface of the sheet 19, following which the cleaning strip is adhesively secured to the assembly, as illustrated at IX. The strip S is then suitably cut to provide a circular configuration to the sheet 3, as illustrated at X, completing the manufacture. In some cases it may be desirable to initially secure the pad with or without the gel 16 to the cover sheet 22 and then secure the cover sheet to the assembly. It will be noted that the various production steps are each simple in themselves and as the adhesive coatings enable fast and effective connection between the respective parts, assembly may be performed at a very rapid rate. It will be particularly noted that the enclosure of the pad 15 and its contents of conductive material by the pad 15', polyethylene ring 21, and sealed by the respective polyethylene-vinyl laminated sheets 5 and 22, insure an air-tight sealing of the conductive material whereby the same may be stored over relatively long periods without material deterioration. The inclusion of the cleaning strip 25, while not directly required with an electrode structure, enables the operator to quickly and effectively prepare the skin surface prior to the mounting of the electrode without other apparatus and at the same time provides an individual cleaning member for each electrode. Having thus described my invention it will be obvious that various immaterial modifications may be madein the same without departing from the spirit of my invention. I claim as my invention: 1.
