Method and an apparatus for adjusting Blood circulation in a limb
First Claim
Patent Images
1. An apparatus for adjusting blood circulation in a limb, comprising:
- a pressure applying band, having a central longitudinal axis and parallel lateral edges, configured for circumferentially wrapping a portion of the limb and applying a first circumferential pressure beneath said parallel lateral edges and a second circumferential pressure beneath a proximity of said central longitudinal axis;
wherein said first circumferential pressure is lower than said second circumferential pressure.

Abstract
A mechanized tourniquet adapted for application in a surgery, emergency or military situation to stop arterial blood loss in an injured limb, which is optionally activated by a user or automatically by detecting therein the free tip of its pressure-applying band. The tourniquet and its electromechanical tension device are automatically controlled by means of the band tension controlling mechanism and a timer initialized by a safety signal.

11. An apparatus for adjusting blood circulation in a limb, comprising:
-
a pressure applying band configured for being wrapped around the limb to apply a circumferential pressure thereon; a traction mechanism configured for pulling said pressure applying band tightly around the limb; at least one sensor configured for measuring said circumferential pressure; and a pressure adjusting module configured for activating said traction mechanism according to said measured applied pressure for adjusting said circumferential pressure. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
