Abrasive skin electrode
First Claim
1. A disposable medical electrode for improving the quality of biopotential event detection by minimizing motion artifacts arising from the skin of a patient, said electrode comprising:
- conductive means capable of detecting and transmitting biopotential events for recording;
abrasive means operatively associated with said conductive means for abrading the epidermal layer of the skin of the patient;
holding means associated with said conductive means for securing the electrode to the skin of the patient with said abrasive means in contact with the skin of a patient, said abrasive means is spaced apart from said conductive means and is movable relative to the skin and said conductive means upon application of the electrode to the skin of the patient; and
said holding means including a sheet member and said sheet member having an adhesive material thereon to secure the electrode to the skin of the patient while allowing said abrasive means to be movable with respect to the skin of the patient and said sheet member.

Abstract
A medical electrode and skin preparation device is adapted to be secured to the skin of a patient and is designed to prepare the skin by abrasion or penetration of the epidermal layer of the skin in contact with the conductive means of the electrode after the electrode is secured in place on the skin. The electrode includes a penetrating device associated with a conductor capable of transmitting biopotential events for recording, with the conductor being retained by an adhesive member which secures the electrode to the skin of the patient. The penetration device in contact with the skin is movable relative to the skin of the patient and a holder by an applicator gun to abrade or penetrate the epidermal layer of skin after the electrode is placed on the skin. Uniform skin preparation is achieved by a flexible screen member and an electrolyte gel reservoir on the electrode and an applicator gun which minimizes motion artifacts arising from skin potential variations.

12. A disposable medical electrode which allows preparation of the skin of a patient to reduce motion artifacts after application of the electrode to the skin of the patient, said electrode comprising:
-
an electrically conductive member having a surface facing the skin of a patient in use when the electrode is adhered to the skin; a retaining member in operative engagement with said conductive member; a flexible sheet member secured to said retaining member and said sheet member having an adhesive thereon for adhering the electrode to the skin of the patient; a flexible abrasive member in operative engagement with said retaining member and spaced apart from and movable relative to said conductive member; an electrolyte gel in operative contact with said conductive member and the skin of the patient when the electrode is secured to the skin of the patient, said conductive member and abrasive member being rotatable relative to the skin and said retaining member and wherein said sheet member adheres the electrode to the skin of the patient to enable the abrasion of the portion of the skin in contact with the abrasive member to minimize motion artifact while forming a reservoir area of said gel generally between said abrasive member and said conductive member. - View Dependent Claims (13, 14)

15. A disposable pre-gelled medical electrode which reduces motion artifacts, said electrode comprising:
-
an electrically conductive member having a first surface oriented to face the skin of the patient when the electrode is placed on the skin of the patient in use and an opposing stud on a second surface thereof for connection to an external electrically responsive monitor; an electrically non-conductive housing retaining said conductive member therein, said housing including an annular opening receiving said conductive member therein; a flexible abrasive member operatively retained by said housing and including a gel in contact with said conductive member, said abrasive member being movable relative to said conductive member and said abrasive member and said housing further forming a gel reservoir area therebetween such that when said abrasive member is pressed against the skin of the patient said gel flows into said reservoir area; and a sheet member operatively associated with said housing and having an adhesive material thereon to secure the electrode to the skin of the patient while allowing said abrasive member to be movable with respect to the skin of the patient and said sheet member. - View Dependent Claims (16, 17, 18)
