Inflatable tourniquet to aid in establishing intravenous access and method thereof

摘要

A device to aid in establishing intravenous access by means of a sequential trapping and displacing of the venous blood in a top to bottom action down an extremity, resulting in a localized increase in the diameter of the veins, due to increased, trapped blood volume. The resulting distention of the vessels produces a stabilizing effect, thereby decreasing vascular mobility and rolling. The combination of vessel distention and stabilization greatly facilitates the obtaining of a patent I.V. The sequential trapping and milking of venous blood toward the extremity is accomplished via a specialized inflatable bladder.
