Apparatus for an adjustable radial and ulnar compression wristband

Abstract

An adjustable radial and ulnar vascular compression wristband assists in achieving partial or full occlusion of a blood vessel when applied to a patient's wrist during or following a medical procedure. At least two adjustably inflatable non-adjacent balloons on the wristband apply preferential compression to portions of the circumference of the wrist, including in particular those portions overlying the ulnar and radial arteries.

We claim: 
     
         1 . A means for achieving patent hemostasis of a puncture site in a blood vessel in a wrist that includes at least a flexible strap having a longitudinal length and two ends at opposite sides of the longitudinal length, a securement means for circumferential positioning and fastening the strap circumferentially around the wrist, and a compression means for applying preferential compression onto a radial artery and an ulnar artery in said wrist, said compression means including at least two inflatable non-adjacent balloons, a first of said at least two inflatable non-adjacent balloons is for placement over the radial artery but not the ulnar artery of said wrist when a second of said at least two inflatable non-adjacent balloons is over the ulnar artery but not the radial artery in said wrist, the second of the balloons is non-movable relative to the two ends of said strap along the longitudinal length, and the first balloon is not non-movable and is located on a cuff slidably movable along the longitudinal length of the strap, and an inflation means and an adjustment means for adjustably applying said compression. 
     
     
         2 . The compression means of  claim 1  wherein at least one of the at least two balloons includes on one side at least two lines or marks placed such that they cross each other, at such intersection of which is located an enlarged area. 
     
     
         3 . At least one of the balloons of  claim 1  is more particularly strengthened by including on its top side at least two layers of material, each affixed to the other along at least one portion of said top side. 
     
     
         4 . The strap and at least one of the balloons of  claim 1 , which are more particularly composed of at least one selected from the group of materials comprising polyvinyl chloride, vinyl, polyethylene, polyurethane and nylon material. 
     
     
         5 . At least one of the balloons of  claim 1  that further includes a hemostatic agent attached to its bottom surface. 
     
     
         6 . A wristband for the purpose of achieving patent hemostasis of a puncture site in an artery in a wrist, the wristband comprising at least: a flexible strap having a longitudinal length and a width and two ends at opposite sides of the longitudinal length, hook and loop material placed at the two ends of said strap, two inflatable non-adjacent balloons each having a top side positioned along a portion of the longitudinal length of the strap and a tube connecting each balloon to a connector, wherein:
 each of the two balloons extends substantially across the entire width of the strap;   the two balloons are sized and positioned such that a first of said balloons is for placement over a radial artery but not an ulnar artery of said wrist when a second of said balloons is over the ulnar artery but not the radial artery in said wrist;   the second of the balloons is non-movable relative to the two ends of said strap along the longitudinal length, and the first balloon is not non-movable and is located on a cuff slidably movable along the longitudinal length of the strap.   
     
     
         7 . At least one of the balloons of the wristband of  claim 6  is more particularly strengthened by including on its top side at least two layers of material, each affixed to the other along at least one portion of said top side. 
     
     
         8 . The strap and at least one of the balloons of  claim 6 , which are more particularly composed of at least one selected from the group of materials comprising polyvinyl chloride, vinyl, polyethylene, polyurethane and nylon material. 
     
     
         9 . The wristband of  claim 6 , that further includes a hemostatic agent attached to a bottom surface of at least one of said balloons. 
     
     
         10 . The wristband of  claim 6  wherein at least one of the at least two balloons includes on one side at least two lines or marks placed perpendicularly to and crossing each other, at the intersection of which is located an enlarged area. 
     
     
         11 . A wristband for the purpose of achieving patent hemostasis of a puncture site in an artery in a wrist, the wristband comprising at least: a flexible strap having a longitudinal length and a width and two ends at opposite sides of the longitudinal length, hook and loop material placed at the ends of said strap, two inflatable non-adjacent balloons each having a top side positioned along a portion of the longitudinal length of the strap, and a tube connecting each balloon to a connector, wherein:
 each of the two balloons extends substantially across the entire width of the strap; the two balloons are sized and positioned such that a first of said balloons is for placement over an ulnar artery but not a radial artery of said wrist when a second of said balloons is over the radial artery but not the ulnar artery in said wrist;   the second of the balloons is non-movable relative to the two ends of said strap along the longitudinal length, and the first balloon is not non-movable and is located on a cuff slidably movable along the longitudinal length of the strap;   at least one of the at least two balloons includes on one side at least two lines or marks placed such that they cross each other, at such intersection of which is located an enlarged area.
