Description

ABSTRACT:
A breast marking device includes an annular body and a circular felt marking pad disposed on a front end of body which holds ink. A removable annular cap covers the felt marking pad and is secured to the body. The cap has a pair of annular walls which frictionally engage the body to removably secure the cap to the body. A projection extends from a front face of the cap which defines a circular, pointed, marking edge substantially concentric with the felt marking pad. The marking edge has substantially the same diameter as the felt marking pad. A stop is provided on the body to limit movement of the cap on the body such that the cap engages the stop to space the cap from the felt marking pad. A circular imprint is made on the breast with the marking edge so as to discolor flesh thereof. Once an imprint is made, a circle of ink is stamped with the felt marking pad substantially where the circular imprint was made. Before stamping the circle of ink, the location of the circular imprint is examined to determine whether the location of the circular imprint is accurate. If the location is not accurate, than the circular imprint is rubbed to reduce the discoloration and another circular imprint is made prior to stamping the circle of ink.
