Abstract: Coaguband is a device for applying direct pressure on a bleeding site. It has an adhesive band, and an absorbent in the center which encloses a dome-shaped rubber or plastic component. The band anchors the device on the bleeding site at the same time applying pressure on it, while the dome-shaped component multiplies the pressure exerted by the band. The absorbent absorbs unclotted blood. In most cases, with its dome-shaped component multiplying the pressure exerted by its adhesive band, it effectively replaces the human thumb in applying direct pressure on a bleeding site, freeing the medical personnel for other duties.
