Abstract

A hemostatic compression system facilitates patent hemostasis of an arterial access site on the arm of a wearer. The system includes a radial compression band and a Doppler probe. The radial compression band includes an elongated arm band sized to receive the arm. The compression band also includes a pressure surface coupled to the arm band and facing radially inward for compressive engagement with the access site. The Doppler probe is coupled to the arm band adjacent the pressure surface and is configured to sense blood flow through the artery. Hemostatic compression applied by the radial compression band is variable in response to the sensed blood flow so as to ensure patency of the artery during hemostasis of the site.

Claims

1. A radial compression band configured to provide hemostatic compression to an arterial access site on the arm of a wearer, said radial compression band comprising:

an elongated arm band presenting an opening sized to receive the arm;

an opening-adjustment component operable to adjust the size of the opening; and

a pressure pad projecting radially inward relative to the arm band for engagement with the access site, with adjustment of the opening size by the component serving to vary the pressure applied by the pad against the access site,

said pressure pad being shiftably coupled to the arm band for variable positioning along the length thereof.

2. The radial compression band as claimed in claim 1,

said arm band having an adjustable length so that the opening size is adjustably defined by the arm band and further adjustable by the opening-adjustment component.

3. The radial compression band as claimed in claim 2,

said arm band including at least one adjustment strap that permits selective adjustment of the length of the arm band.

4. The radial compression band as claimed in claim 3,

said arm band being continuous so as to fully encircle the opening.

5. The radial compression band as claimed in claim 1,

said opening-adjustment component and the pressure pad being generally diametrically opposed from one another.

6. The radial compression band as claimed in claim 1,

said arm band including an elongated frame extending lengthwise along the band,

said pressure pad being shiftable along the length of the frame.

7. The radial compression band as claimed in claim 6,

said arm band including a slider connected to the frame for sliding movement along the length thereof,

said pressure pad being fixed to the slider.

8. The radial compression band as claimed in claim 6,

said opening-adjustment component and the pressure pad being generally diametrically opposed from one another.

9. The radial compression band as claimed in claim 6,

said arm band presenting proximal and distal margins, with the opening being defined between the margins,

said frame presenting an access opening located between the proximal and distal margins so as to expose the underlying portion of the arm.

10. The radial compression band as claimed in claim 6,

said frame presenting opposite frame ends,

said arm band including a flexible strap interconnecting the frame ends,

said frame being at least substantially rigid relative to the strap.

11. The radial compression band as claimed in claim 1,

said opening-adjustment component including an expandable bladder positioned in generally diametric opposition to the pressure pad.

12. The radial compression band as claimed in claim 11,

said arm band including an elongated frame extending lengthwise along the band to present opposite frame ends,

said pressure pad being shiftable along the length of the frame,

said arm band including a flexible strap interconnecting the frame ends,

said expandable bladder being coupled to the flexible strap.

13. A hemostatic compression system for facilitating patent hemostasis of an arterial access site on the arm of a wearer, said hemostatic compression system comprising:

a radial compression band configured to provide variable hemostatic compression to the arterial access site, said radial compression band including—

an elongated arm band presenting an opening sized to receive the arm,

a pressure surface coupled to the arm band to face radially inward for compressive engagement with the access site; and

a Doppler probe coupled to the arm band so as to be located adjacent the pressure surface,

said Doppler probe being configured to sense blood flow through the artery, with hemostatic compression applied by the radial compression band being variable in response to the sensed blood flow so as to ensure patency of the artery during hemostasis of the site.

14. The hemostatic compression system as claimed in claim 13,

said arm band having an adjustable length so that the opening size is adjustably defined by the arm band, with adjustment of the opening size serving to vary the pressure applied by the pressure surface.

15. The hemostatic compression system as claimed in claim 14,

said arm band including at least one adjustment strap that permits selective adjustment of the length of the arm band.

16. The hemostatic compression system as claimed in claim 15,

said arm band being continuous so as to fully encircle the opening.

17. The hemostatic compression system as claimed in claim 14,

said radial compression band including an opening-adjustment component operable to further adjust the size of the opening.

18. The hemostatic compression system as claimed in claim 13,

said radial compression band including an opening-adjustment component operable to adjust the size of the opening,

said opening-adjustment component and the pressure surface being generally diametrically opposed from one another.

19. The hemostatic compression system as claimed in claim 13,

said arm band including an elongated frame extending lengthwise along the band,
