Definitions
- shaped initially dry absorbent bodies or sponges are adhered centrally to adhesive patches each sized to ultimately adhere an assembled electrode to the body of a subject.
- the sponges are then soaked with an adequate supply of electrolyte and the resulting electrolyte carrier components are placed for storage in wells of a storage tray, utilizing exposed adhesive on the adhesive patches for sealing attachment of the electrolyte carriers to the storage tray.
- FIG. 1 is a perspective view with a portion broken away illustrating a tray supporting thereon a plurality of disposable electrolyte carrier components.
- FIG. 5 is a fragmentary perspective illustration of an assembled electrode applied to the unshaven scalp of a subject.
- the electrolyte soaked bodies 18 have diameters which are small in relation to the inside diameters of the wells 12, such that when the patches 14 are peeled away from the tray 10 none of the electrolyte contained in the absorbent bodies 18 will be transferred to the walls of the wells 12.
- the bodies 18 may be prefilled each with a measured quantity of electrolyte and since the bodies 18 are sized so as not to physically contact the tray 10, none of the measured quantity of electrolyte will be lost by transfer to the surfaces which form the wells 12.
- the terminal 32 is preferably a very high quality silver, such as 99.9% silver, and the terminal lug extending through the sleeve 30, being one piece with the terminal ring 34, would of course comprise the same high quality silver.
- the outer surfaces of the terminal ring 34 are preferably chlorided by contacting the ring 34 with any suitable chloriding solution. This chloridization preferably occurs before the sleeve 30 is shrunk into position so as to assure that no part of the terminal ring 34, which is later permitted to contact electrolyte as will be explained, has not been first chlorided.
- the sleeve 30 is preferably any moisture impervious heat shrinkable plastic, such as tetrafluoroethylene (Teflon).
- the end of the conductor 27 which has been soldered to the terminal lug covered by the sleeve 30 may be referred to as the proximal end of the wire 28.
- the opposite or distal end of the wire 28 is soldered, or otherwise connected, to a conventional bayonet plug 26 which, as will be described, is used for connecting the assembled electrode to an external signal monitoring device, such as an electroencephalograph recording device.
- FIG. 4 illustrates the ring 34 and associated wire 28 before assembly to the disposable component in solid lines and shows by broken lines the manner in which the ring 34 fits over the electrolyte soaked body 18 so as to become adhered to the adhesive layer 16 present on the patch 14 and surrounding the body 18.
- wires 28 and receptacles 24 employed during any monitoring procedure varies depending upon the number of traces or channels forming the montage desired to be accomplished.
- wires 28 may be color coded or otherwise marked to simplify wire selection for montage formation.
- an attendant has selected a given one of the wires 28 for passage of its terminal ring portion 34 onto an electrolyte soaked body 18 protruding from an adhesive patch 14.
- the assembled electrode is applied to the patient's scalp after separating the patient's hair so as to form a part 36 which exposes a portion of the patient's skin surface 38.
- the direction in which the part 36 extends will obviously depend on the direction in which the patient's hair has been parted and the location of the electrode along such part in turn depends upon the nature of the montage sought to be produced.
- the illustrated elliptical shape for the patches 14 is preferred.
- the direction in which a particular part of the patient's hair extends is subject to the control of the attendant who can so arrange the hair partings that the major axes of the elliptical patches extend along the hair partings so as to maximize adhesive contact with the skin exposed by such partings without, at the same time, generating unmanageable overlaps between patches required to be mounted in close proximity.
- the wire 28 also extend along the part 36 so that a minimum of the patient's hair lies under the wire 28, with the consequence that the wire position is firmly anchored and tensions developed along the length of the wires will have a minimal affect upon the electrode position.
- the electrolyte loaded body 18 will be compressed in that the body 18 is longer than the ring portion 34 is thick. This compression generously wets with electrolyte the patient's scalp under the patch 14 and, at the same time, expands the body 18 against the inside wall of the ring 34 so as to effect a secure attachment between the body 18 and the ring 34. Inasmuch as the rings 34 will have been prechlorided, or otherwise treated, it can be appreciated that assembled electrodes are ready immediately for signal monitoring.
- the patches 14 with their accompanying electrolyte loaded bodies 18 have been characterized as disposable electrolyte components, or carriers.
- the patches 14 may be readily removed from the patient's scalp with the aid of a solvent in conventional fashion and then the patches 14, together with the electrolyte loaded bodies 18, discarded.
- the lead wire 28 together with the prechlorided terminal ring 34 may then be cleaned under suitably aseptic conditions and reused with a clean and previously unused disposable electrolyte carrier.
- the number of times the reusable electrode part may be reused will, of course, depend upon the permanency of the chloriding process or other electrode preparation procedure and the abrasiveness of the aseptic cleaning process used between successive monitoring operations.
- chloriding is frequently the most desirable preparation for an electrode metal such as silver which is relatively noble and that when lesser electrode metals, such as tin or copper, are to be employed in the practice of the present invention, chloriding may be less desirable.
