Abstract

An anti-snag device for use with an electrocardiographic electrode lead clip having moveable arms for engaging the electrode. A lead wire extends from one of the arms. The anti-snag device comprises an elongated means extending from the other arm and joined to the lead wire so as to provide a smoothed configuration to the lead clip. The anti-snag device may comprise a piece of tubing, one end of which is inserted over the arm of the lead clip and the other end of which is fastened to the wire. The anti-snag device may also comprise an integral extension of the arm.

Claims

1. An anti-snag device for use with a lead clip having an electrical contact portion for engaging an electrocardiographic electrode, said electrical contact portion having first and second generally adjacent arms, each of said arms having one end fixed to said electrical contact portion and a free end, said arms being moveable toward and away from each other for opening and closing the clip, said first arm having a lead wire extending from the free end thereof, said anti-snag device comprising:

elongated means extending from the free end of said second arm and engaging said lead wire at a point removed from the free end of said first arm, said elongated means having sufficient length to permit said toward and away movement of said arms.

2. The anti-snag device according to claim 1 wherein the end of said elongated means that engages said lead wire contains a hole through which said lead wire extends.

3. The anti-snag device according to claim 1 wherein the end of said elongated means that engages said lead wire includes a loop for engaging said lead wire.

4. The anti-snag device according to claim 1 wherein said elongated means comprises an integral extension of said second arm.

5. The anti-snag device according to claim 1 wherein said elongated means loosely engages said lead wire.

6. The anti-snag device according to claim 5 wherein said elongated means comprises a tube having one end engaging the free end of said second arm and the other arm engaging said lead wire.

7. The anti-snag device according to claim 1 wherein said elongated means is flexible to facilitate the toward and away movement of said arms.

8. The anti-snag device according to claim 7 wherein one end of said tube is slid over the free end of second arm.
