Skin screw electrodes

摘要

Electrodes providing excellent recording and physical stability. Electrodes are disclosed that may include a plurality of small teeth that possess a novel design shape and orientation. The shallow and relatively long teeth run parallel to the rim of the electrode that presses against the patient's skin. When the electrode is twisted onto skin, the tiny teeth penetrate the stratum corneum and move nearly horizontally under the stratum corneum, thus anchoring the electrode securely to the skin. The electrodes cause minimal discomfort to the patient since the small teeth do not extend to the pain fibers which are located in deeper layers of the skin. The electrodes may be fabricated in a variety of geometries including cylindrical, disk, and blunt bullet or top shapes. In some instances, the electrodes may be connected to detachable leads having magnetic properties.

主权项

1. An electrode system for attaching an electrode to skin of a patient, comprising: an electrode having an electrode body comprising an electrode face that is adapted to be pressed against the skin of the patient, wherein said electrode face includes a plurality of teeth that includes teeth located on a rim at a perimeter of said electrode body, wherein each of said plurality of teeth includes a shaft that initially extends from said electrode face, the shaft then turning to run at an orientation that is within about 5° away from the rim to a depth that is less than a depth of stratum corneum of said patient.
