Abstract

A vascular compression apparatus and method for applying pressure onto an area of a patient generally including a blood vessel and a wound site, such as a blood vessel puncture after a cannulated procedure, for the purpose of controlling bleeding and achieving hemostasis.

Claims

1. A radial artery compression system comprising a radial artery compression device, the radial artery compression device adapted to allow a user to provide varying degrees of pressurization against a patient'"'"'s radial artery to maintain a desired degree of hemostasis at a percutaneous access site, the radial artery compression device comprising:

a body, the body comprising a pump a pressure regulator and a pressure bladder; and

securing means to secure the body to the underside of a wrist of a patient in the area of the radial artery, such that the pressure bladder can be positioned adjacent the wrist of the patient wherein the user activates the pump to inflate the pressure bladder between a first position and at least a second position to provide varying degrees of pressurization to the wrist of a patient, wherein when the pressure bladder is in a first position, the pressure bladder is positioned adjacent the body and applies a lesser degree of pressurization against the wrist of the patient and when the pressure bladder is in the second position, the compression pad is positioned a given amount of displacement from the body and provides a greater amount of pressurization against the patient'"'"'s wrist.

2. The radial artery compression system of claim 1 further comprising a brace, the brace being adapted to restrict movement of the wrist.

3. The radial artery compression system as in claim 1 further comprising a compression pad comprised of a hemostatic agent.

4. The radial artery compression system according to claim 1 wherein the hemostatic agent is Poly-N-Acetyl-Glucosamine.

5. The radial artery compression system according to claim 1, wherein the pressure bladder is in continuous fluid communication with the pump.

6. The radial artery compression system as in claim 1, wherein the pressure bladder is in direct fluid communication with the pressure regulator and the pressure regulator, pressure bladder and pump are all form a unitary component.

7. The radial artery compression system of claim 1, wherein the securing means is a single unitary piece.

8. The radial artery compression device of claim 1, wherein when the device is secured to the underside of the wrist of a patient, as the pressure bladder is inflated to cause the compression pad to exert a force toward the wrist and radial artery of the patient, the pressure bladder gradually applying pressure to the radial artery of the patient.

9. The radial artery compression device of claim 8, wherein the device is configured to apply pressure to the radial artery in a manner that prevents blood from flowing out through an opening in the radial artery to thereby achieve hemostasis at the opening.

10. The radial artery compression device of claim 6, wherein the pump further comprises an integral check valve.

11. The radial artery compression device of claim 6, further comprising a channel between the pressure bladder and the pressure regulator.

12. The radial artery compression device of claim 11, further comprising a flow restrictor disposed in the channel.

13. The radial artery compression device of claim 1, wherein the pressure regulator is configured to, once the pressure bladder has been inflated, to reduce the pressure in the pressure bladder to a desired level.

14. The radial artery compression device as in claim 1, further comprising a restrictor.

15. The radial artery compression device as in claim 1, wherein the compression bladder is a disk shaped.

16. A method for compressing a radial artery at an access site of a radial artery of a patient, the method comprising:

(a) providing a radial artery compression device comprising, a pump to be actuated by a user by application of pressure to said pump, a pressure bladder capable by being inflated by the pump and pressure regulation means for regulating the pressure exerted by the pressure bladder;

(b) positioning the device such that the pressure bladder is in contact with the underside of the patient'"'"'s wrist near an access site, the access site providing access to the radial artery;

(c) attaching the device to the wrist of a patient, with the pressure bladder;

(d) actuating the pump and inflating the pressure bladder to a desired pressure.

17. The method of claim 16, wherein a device is inserted into the radial artery via the access site.

18. The method of claim 16 wherein the pressure provided by the pressure bladder is sufficient to cause hemostasis.
