Radial compression hemostasis band with Doppler confirming vascular patency
First Claim
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 arm opening sized to receive the arm;
said arm band presenting proximal and distal margins, with the arm opening being defined between the margins,an opening-adjustment component operable to adjust the size of the arm opening; and
an arterial pressure pad projecting radially inward relative to the arm band for engagement with the access site, with adjustment of the arm opening size by the component serving to vary the pressure applied by the pad against the access site,said arm band presenting a window located between the proximal and distal margins so as to expose the underlying portion of the arm,said pressure pad located radially inboard of the window and extending across at least part of the window so as to visibly facilitate engagement of the pressure pad with the access site.

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.
