Abstract: A releasably locking umbilical cord clamp including one or more of: a gender-identifying color, a grasping portion to facilitate closing and locking the clamp on the remaining umbilical cord, a fluid removal channel, a separable measurement portion to facilitate positioning of the clamp at a suitable location on an umbilical cord, and an operatively associated key to unlock and reposition or remove the clamp. Also included are methods relating to using a gender-identifying color on an umbilical cord clamp to facilitate gender and identity recognition and methods of applying the clamp at the proper distance.

Abstract: A retractable card carrying holder is provided for retention of identification cards, particularly for use when traveling through security checkpoints. The photo ID card(s) can be disposed within a transparent sleeve which is attached by a retractable tether to an opaque enclosure into which it is operatively associated, which enclosure includes a clip or other fastener operatively associated thereto to clip onto a belt, backpack, luggage, a wearer, or other clothing. Preferably, at least one of the sleeve or the enclosure is sufficiently non-deformable to inhibit or avoid damage to the card(s). Methods using the card(s) are also included.
