Radial artery clamp

Claim 2

An artery clamp comprising: a band member, placeable around the arm of a patient, and, a pressure pad member, mounted on said band member, said pressure pad member including a first leg for applying pressure to the radial artery of the arm of a patient, and a second leg, spaced from said first leg, for contacting the arm of the patient to stabilize said pad member, said second leg being disposed and sized so as not to apply sufficient pressure to the ulnar artery of the arm of the patient to totally block the flow of blood therethrough, said first and second legs each defining a skin contacting surface, the area of the skin contacting surface of said first leg being substantially greater than the area of the skin contacting surface of said second leg, whereby circulation of blood to the hand of the patient is maintained.

Claim 3

The artery clamp of claim 1 wherein the area of said skin contacting surface of said first leg is approximately three times greater than the area of said skin contacting surface of said second leg.

Claim 4

The artery clamp of claim 1 wherein the area of said skin contacting surface of said first leg is about 0.3 square inches and the area of said skin contacting surface of said second leg is about 0.1 square inches.

Claim 5

The artery clamp of claim 1 wherein said pad member defines an opening for receiving said band member.

Claim 6

The artery clamp of claim 4 wherein said opening is sized and shaped for snugly receiving and frictionally engaging said band member, thereby resisting movement of said pad member along said band member.

Claim 7

The artery clamp of claim 1 wherein said first leg and said second leg are spaced apart by approximately 0.8 inches.

Claim 8

The artery clamp of claim 1 wherein said pad member is comprised of a generally clear plastic material.

Claim 9

The artery clamp of claim 1 wherein said pad member is comprised of a generally clear plastic material having a hardness of between about 40 and 50 Shore A.

Claim 10

The artery clamp of claim 1 wherein said pad member comprises a unitarily formed plastic pad member.

Claim 11

The artery clamp of claim 1 wherein said band member includes a buckle means, and said pad member is mounted to said band member so that said first leg is disposed closer to said buckle means than said second leg.

Claim 12

An artery clamp comprising a band member placeable around an arm of a patient, and a resilient, unitary pressure pad member having a first end and a second end, and defining an opening for receiving said band member, said opening being sized to frictionally engage said band member to resist movement of said pad member on said band member, said pad member including a downwardly extending first leg, disposed adjacent said first end of said pad member, said first leg including a skin contacting surface for applying pressure to the radial artery of the patient, and a downwardly extending second leg disposed adjacent said second end, in a spaced relation from said first leg, said second leg including a skin contacting surface for applying pressure to the arm of the patient to prevent movement of said pad member relative to the arm while permitting the flow of blood in the ulnar artery of the patient, said skin contacting surface of said second leg being substantially smaller than said skin contacting surface of said first leg.

Claim 13

An artery clamp comprising a band member placeable around an arm of a patient, and a resilient, unitary pressure pad member having a first end and a second end, and defining an opening for receiving said band member, said opening being sized to frictionally engage said band member to resist movement of said pad member on said band member, said pad member including a downwardly extending first leg, disposed adjacent said first end of said pad member, said first leg including a skin contacting surface for applying pressure to the radial artery of the patient, and a downwardly extending second leg disposed adjacent said second end, in a spaced relation from said first leg, said second leg including a skin contacting surface for applying pressure to the arm of the patient to prevent movement of said pad member relative to the arm while permitting the flow of blood in the ulnar artery of the patient, said skin contacting surface of said second leg being substantially smaller than said skin contacting surface of said first leg.

Claim 14

The artery clamp of claim 11 in which said pad member is formed of a generally transparent plastic material.
