Prophylactic needle guards or sheaths for protecting medical needles and persons using the medical needless either before or after use of the needle. The prophylactic needle guards have a flared portion in order to provide safe insertion of a medical needle into a protective hollow body portion. The needle guard includes structures which are configured to engage at least one of a variety of differently sized and configured wing portions found in medical needles. The needle guard may include a pair of projections that engage corresponding holes within the wing portions of medical needles that includes wings too large to enter the flared portion. Alternatively or in addition to the projections, the needle guard may include one or more interior annular grooves disposed on an inner surface of the flared portion that engage the wing portions of medical needles that have wings that are small enough to enter the flared portion.
