Abstract
Abstract A disposable electrode assembly for establishing electrical contact with an underlying skin surface includes a relatively thin transparent base member having a central hub portion and an adhesive-coated undersurface, a conductive gel-impregnated sponge contact contained in a downwardly facing recess located in the hub, and a relatively thick and inflexible cover member coextensive with the base member. In storage the cover member is attached to the undersurface of the base member by the adhesive and the sponge is confined within the recess. Prior to use the base member is peeled away from the cover member to expose the adhesive surface, which when applied to a skin surface holds the sponge contact in compression-contact therewith. The base is transparent to enable the user to detect skin irritation and incomplete adhesion of the base member, and may be provided with apertures to facilitate breathing of the underlying skin. A combined container and dispenser for conveniently storing and dispensing the electrode assemblies is shown.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
161 words
A dispenser for dispensing disposable body electrode assemblies of the type having disc-shaped base and cover members joined during storage by an interposed layer of adhesive and forming a relatively thin stiff peelably separable assembly, said dispenser comprising, in combination: a housing forming an elongated chamber for receiving a plurality of said electrode assemblies in stacked relationship, said chamber having a uniform inside cross-section along its length complementary to the outside dimension of said electrode assemblies; mounting means for supporting said housing in a substantially vertical upstanding relationship whereby said electrode assemblies are contained in said chamber in a substantially vertical stacked relationship; means comprising a dispensing station at the bottom end of said housing for enabling a user to remove said body electrodes one at a time from said chamber; said dispensing station includes a bottom passageway to pass a single one of said disc-shaped body electrodes at one time; and said passageway is closed throughout opposing peripheral extents thereof.
Claim 2
Dependent Claim
161 words
A dispenser for dispensing disposable body electrode assemblies of the type having disc-shaped base and cover members joined during storage by an interposed layer of adhesive and forming a relatively thin stiff peelably separable assembly, said dispenser comprising, in combination: a housing forming an elongated chamber for receiving a plurality of said electrode assemblies in stacked relationship, said chamber having a uniform inside cross-section along its length complementary to the outside dimension of said electrode assemblies; mounting means for supporting said housing in a substantially vertical upstanding relationship whereby said electrode assemblies are contained in said chamber in a substantially vertical stacked relationship; means comprising a dispensing station at the bottom end of said housing for enabling a user to remove said body electrodes one at a time from said chamber; said dispensing station includes a bottom passageway to pass a single one of said disc-shaped body electrodes at one time; and said passageway is closed throughout opposing peripheral extents thereof.
Claim 3
Dependent Claim
27 words
A dispenser as defined in claim 1 wherein said bottom passageway is a slot arranged in a plane at right angles to the axis of said chamber.
Claim 4
Dependent Claim
49 words
A dispenser as defined in claim 1 which includes means for mounting said housing with the axis of said chamber substantially vertical whereby as the bottom electrode assembly in said chamber is removed through said slot the next adjacent electrode assembly stacked thereabove falls into position behind said slot.
Claim 5
Dependent Claim
13 words
A container assembly as defined in claim 3 wherein said chamber is cylindrical.
Claim 6
Dependent Claim
44 words
A dispenser as defined in claim 1 wherein said bottom end of said container is open, and said bottom passageway comprises a shelf underlying said bottom end of said container, said shelf being dimensioned to receive the bottom one of said stacked electrode assemblies.
Claim 7
Dependent Claim
47 words
A dispenser as defined in claim 5 wherein said shelf is inclined slightly downwardly with respect to the axis of said housing to separate at least a portion of the edge of the bottom one of said stacked electrode assemblies from the next adjacent electrode assembly above.
Claim 8
Dependent Claim
32 words
A dispenser as defined in claim 6 wherein said shelf includes a ledge adjacent at least a portion of its periphery to index said bottom electrode for convenient removal by a user.
