Abstract

The present invention relates to devices, methods, and systems for abrading the skin in preparation for attachment of an electrode. In some embodiments, the invention may provide for a simple, low-cost device 120 with a flat, abrading surface that removes the topmost layer of the skin without causing undue injury.

Claims

1. A dermal preparation device for preparation of the stratum corneum of a patient for adhesion of an electrode to the patient, comprising:

a support layer having an upper surface, a lower surface, a major axis extending through a geometrical center of the support layer and along the longest dimension of the support layer;

an abrasive adhered to the lower surface;

a handle secured to the upper layer; and

wherein the handle is formed by bonding a first portion of a handle layer to the support layer, and folding a second portion of the handle layer to form the handle.

2. A dermal preparation device as in claim 1, wherein the support layer is approximately circular, and the major axis is a diameter of the circle.

3. A dermal preparation device as in claim 1, wherein the major axis is no more than about 2.5 inches long.

4. A dermal preparation device as in claim 1, wherein the major axis is no more than about 2.0 inches long.

5. A dermal preparation device as in claim 1, further comprising an atraumatic peripheral edge.

6. A dermal preparation device as in claim 5, wherein the atraumatic peripheral edge comprises a rounded surface formed by inclining a peripheral edge of the device away from a plane defined by the lower surface, in the direction of the upper surface.

7. A dermal preparation device as in claim 1, wherein the support layer is sufficiently flexible that when pressed against a dermal surface using the handle, the lower surface will deform into a convex surface against the dermal surface.

8. A dermal preparation device as in claim 1, wherein the handle is bonded to the support layer along a bond which extends at least about 50% of the maximum dimension of the support, along the axis of the bond.

9. A dermal preparation device as in claim 1, wherein the handle is bonded to the support layer along a bond which extends at least about 85% of the maximum dimension of the support, along the axis of the bond.

10. A dermal preparation device as in claim 1, wherein the handle is bonded to the support layer by a bond which covers at least about 15% of the total area of the upper surface of the support layer.

11. A dermal preparation device as in claim 1, wherein the handle is bonded to the support layer by a bond which covers at least about 35% of the total area of the upper surface of the support layer.

12. A dermal preparation device as in claim 1, wherein the abrasive comprises a grit with diameters ranging from about 36-66 μ

m.

13. A dermal preparation device as in claim 8, wherein the axis of the bond is substantially parallel to the major axis.

14. A transdermal electrode and surface preparation kit, comprising at least one transdermal electrode configured for adhesive attachment to a patient'"'"'s skin, and at least one dermal preparation device as in claim 1.

15. A dermal preparation device for preparation of the stratum corneum of a patient for adhesion of an electrode to the patient, comprising:

an abrasive surface;

an inner layer; and

,

a holding layer further comprising a gripping portion.
