ABSTRACT:
A tubular inflated bag is progressively rolled onto a limb thereby applying continuous pressure to the limb. The bag is initially located about a tubular support and the limb to be treated is located axially parallel with respect to the support. An outer sleeve surrounds the tubular bag and is progressively moved toward the limb. As the sleeve moves toward the arm, the progress of the sleeve causes the bag to roll onto the limb progressively applying pressure to the limb. The progress of the sleeve is twice as fast as the progress of the bag. Therefore, the sleeve may be telescoping or collapsible so that the sleeve does not unnecessarily limit the movement of the bag.
