Skin preparation method and product
First Claim
1. A product comprising a substantially moisture and air impervious container and a pencil-like device packaged in said container, said pencil-like device comprising a housing and a bundle of relatively stiff fibers gathered together by and retained in the housing, said gathered fibers being stiff enough to dislodge cells from the horny layer of skin and said housing having an opening through which ends of said fibers project outwardly from said housing, said container and said device being sterilized by irradiation so that upon removal of said device from said container said device will be substantially sterilized and useful for stroking the skin of a patient in preparation for application of an electrolyte for bridging the stroked skin to a signal conductor.

Abstract
Epidermal tissue is prepared and marked prior to attachment thereto of an electrode, such as an electrocardiograph electrode, by gently stroking the epidermal surface with an abrader device having fibers adequately stiff to dislodge cells from the epidermal tissue. The abrader device is sterilized and stored in a protective container prior to use.

5. The method of preparing a subject for monitoring or treatment with an electrode, which method comprises the steps of:
-
gently stroking with a bundle of fibers a portion of an outer layer of the skin of the subject in a region overlying tissue to which electrical contact is to be made, said bundle of fibers being stiff enough to dislodge cells from the horny layer of skin and, in addition, being stiff enough to cause the stroked portion of skin to be marked by a change of color for moments following such stroking; and thereafter locating the marked surface of skin and applying thereto electrolyte for bridging the marked skin to a signal conductor. - View Dependent Claims (6)

- 7. The method of preparing the skin of a patient in a region to be examined or treated, said method comprising the steps of forming a bundle of fibers, sterilizing said fibers, and stroking the skin of the patient with ends of said fibers to remove epidermal cells from such skin.
