Abstract

An umbilical cord clamp, which is optionally releasably lockable, 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.

Claims

1. An umbilical cord clamp comprising:

a pair of arms in angular relation each having a length, rear end portions associated at an apex, and free forward end portions normally disposed in spaced-apart relation and being movable towards each other for clamping an umbilical cord between the arms;

a separable measurement portion that is disposed on at least one arm and has a measurement length transverse to the length of each arm, wherein the measurement length facilitates proper positioning of the clamp on the umbilical cord; and

a locking portion for securing the arms together when the clamp is closed.

2. The umbilical cord clamp of claim 1, wherein the measurement length is at least about 1 cm and the arms are arranged in a generally V-shaped configuration.

3. The umbilical cord clamp of claim 1, wherein the measurement length is from about 1 cm to 4 cm.

4. The umbilical cord clamp of claim 1, wherein the separable measurement portion comprises a plurality of perforations arranged adjacent and at least substantially parallel to the length of each arm to facilitate separation of the separable measurement portion from the clamp.

5. The umbilical cord clamp of claim 1 which further comprises a grasping portion that is disposed on each arm transversely to the length thereof and sufficiently sized and shaped to receive a finger or tool so as to facilitate grasping and closing of the clamp.

6. The umbilical cord clamp of claim 5 wherein the separable measurement portion is releasably attached to an edge of the grasping portion on at least one of the arms.

7. The umbilical cord clamp of claim 5, wherein each grasping portion comprises a single portion integrally formed with at least the arms of the clamp.

8. The umbilical cord clamp of claim 5, wherein each grasping portion is at least about two-thirds of the distance from the rear end portion to the free forward end.

9. The umbilical cord clamp of claim 5, wherein each grasping portion is outwardly concave so as to facilitate receiving the finger or tool being used to grasp the clamp.

10. The umbilical cord clamp of claim 5, wherein each grasping portion is at least 1.5 times as wide as a width of the arm and has a length of at least about 0.5 cm.

11. The umbilical cord clamp of claim 1, further comprising a channel that extends substantially along the length of at least one arm and is open on at least one end to facilitate the escape of fluid therefrom as the clamp is closed.

12. A method of clamping an umbilical cord comprises:

applying the clamp of claim 1 to an umbilical cord at a distance from a newborn'"'"'s stomach that is substantially equivalent to the measurement length; and

removing the separable measurement portion from the umbilical cord clamp.

13. The umbilical cord clamp of claim 1, wherein the locking portion comprises a releasably locking portion for securing the arms together when the clamp is closed and releasing the arms when an operatively associated key is applied so as to facilitate repositioning or removal of the clamp.

14. An umbilical cord clamp comprising:

a pair of arms each having a length in a generally V-shaped configuration having rear end portions associated at an apex and having free forward end portions normally disposed in spaced-apart relation and being movable towards each other for clamping an umbilical cord between the arms;

a grasping portion that is disposed on each arm transversely to the length thereof and sufficiently sized and shaped to receive a finger or tool so as to facilitate grasping and closing of the clamp; and

a locking portion for securing the arms together when the clamp is closed.

15. The clamp of claim 14, wherein the rear end portions are joined by an integral hinge.

16. The clamp of claim 14, wherein the locking portion comprises:

a flexible tongue at the forward end of one of the arms that projects towards the other arm in the general direction of closing movement of the arm; and

a recess at the forward end of the other arm for receiving the tongue and having a pair of transversely-spaced projections extending into the recess from opposite sides thereof,

wherein the tongue has a tip portion and the projections define a pair of forwardly sloping ramp surfaces engagable with the tip portion for flexing the tongue forwardly as the arms are urged together, the tongue having a pair of lateral notches adjacent the tip portion for receiving the pair of projections when the tip portion has cleared the ramp surfaces and the clamp is fully closed.

17. The clamp of claim 16, wherein the projections of the other arm have undersurfaces that slope forwardly and away from the one arm.

18. The clamp of claim 16, wherein the projections extend forwardly a distance greater than the thickness of the tongue, the projections extending forwardly through the notches beyond the tongue when the clamp is closed.

19. The clamp of claim 16, wherein the tip portion has rounded rear edges when viewed in transverse section.

20. The clamp of claim 16, wherein the recess opens forwardly and has a width greater than the width of the tongue, and wherein the sides of the recess are slidably engagable with the tongue for guiding the same into locking position as the clamp is closed.

21. The clamp of claim 14, wherein each grasping portion either:

(a) comprises a single portion integrally formed with at least the arms of the clamp;

(b) is at least about two-thirds of the distance from the rear end portion to the free forward end;

(c) is outwardly concave so as to facilitate receiving the finger or tool being used to grasp the clamp;

or (d) each grasping portion is at least 1.5 times as wide as a width of the arm and has a length of at least about 0.5 cm.

22. The clamp of claim 14, further comprising a channel that extends substantially along the length of at least one arm and is open at the free end portion thereof to facilitate the escape of fluid therefrom when the clamp is closed.

23. The clamp of claim 22, wherein the channel extends substantially along the length of each arm or wherein the channel has a width of about ¼

to ½

of a width of each arm.
