Abstract
A rigid puncture-proof sterilizable shield or guard device and method of use for stylet-type stainless steel needles, functioning preferably in two ways: 1) to protect the user from inadvertent needle sticks when placing the stylet back in the needle hub, and 2) to serve as a needle depth guide insuring exact placement of the needle into the desired body space. Adjustable and fixed or nonmovable versions of the guard may be made preferably as a flared, conical member available at the hub to prevent inadvertent needle sticks.
