First Claim
1. A method for applying a tourniquet to the abdominal region, comprising the steps of:
- a. providing an abdominal tourniquet comprising;
i. an adjustable waist strap for securing said abdominal tourniquet around an abdomen;
ii. a base plate carried by said waist strap having a width greater than said waist strap so that said base plate extends laterally outward from said waist strap to provide a stable base for positioning over a selected area of said abdomen;
iii. an air bladder carried on a bottom side of said base plate having a deflated condition wherein said air bladder is collapsed against said base plate, and an inflated condition wherein said air bladder is expanded to extend outwardly from said bottom side of said base plate;
iv. said air bladder having a generally elongated “
V”
shaped construction so that a wide end of said directed air bladder is generally carried on said bottom side of said base plate and an elongated narrow converging end of said directed air bladder forms an elongated edge positioned away from and parallel to said base plate, and,v. an air source operatively connected in fluid communication with said directed air bladder for operating said directed air bladder between said deflated condition and said inflated condition;
b. securing said waist strap around an abdomen of a person, wherein said air bladder is in contact with the surface of said abdomen and positioned over the aorta at or above the umbilical region of said person;
c. inflating said air bladder with said air source; and
,d. wherein said inflation step causes said elongated edge of said directed air bladder to apply a constricting force against said abdomen such that said aorta is compressed to occlusion.

Abstract
A portable pneumatic abdominal aortic tourniquet for occlusion of the abdominal descending aorta to restrict blood supply to a non-compressible arterial hemorrhage in the abdominal region. The tourniquet comprising an adjustable waist strap for securing around an abdomen; a directed air bladder mounted to the waist strap having a generally “V” shaped construction operable between a deflated condition wherein the directed air bladder is collapsed, and an inflated condition wherein the directed air bladder is expanded for exerting pressure against the abdomen; and, an air source connected to the directed air bladder for operating the directed air bladder between the deflated condition and the inflated condition.

10. A method for using an abdominal aortic tourniquet to stop bleeding in a person comprising:
-
a. providing an abdominal aortic tourniquet, comprising; i. an adjustable waist strap for securing said abdominal aortic tourniquet around an abdomen of a person; ii. a directed air bladder mounted to said waist strap having a generally cuneiform shaped construction having a narrow converging end extending away from said adjustable waist strap to form an edge parallel to said strap, said air bladder operable between a deflated condition wherein said directed air bladder is collapsed, and an inflated condition wherein said directed air bladder is expanded for exerting pressure by said edge into said abdomen; and
,iii. an air source connected to said directed air bladder for operating said directed air bladder between said deflated condition and said inflated condition; b. securing said waist strap around an abdomen of said person, wherein said directed air bladder is in contact with the surface of said abdomen and positioned over the abdominal aorta of said person above the inguinal area of said person; c. inflating said directed air bladder with said air source; and d. wherein said inflation step causes said edge to apply a deforming force across and against said aorta to occlude said same, and wherein said inflation step causes cessation of said bleeding at a location below and away from said point of aortic occlusion.

11. In a human experiencing a hemorrhage below the inguinal area of the body, an abdominal tourniquet adapted for achieving hemostasis at said hemorrhage site comprising:
-
a. an adjustable waist strap adapted for securing said abdominal tourniquet around an abdomen of said body; b. a base plate carried by said waist strap and configured to provide a stable base therefrom, and wherein said base plate is adapted to be positioned over the abdominal aorta above the inguinal area of said body; c. an air bladder carried on a bottom side of said base plate having a deflated condition wherein said air bladder is collapsed against said base plate, and an inflated condition wherein said air bladder is expanded to extend outwardly from said bottom side of said base plate toward said aorta; and
,d. said air bladder having an elongated “
V”
shape and configured so that when in said inflated condition a tip of said bladder penetrates said abdomen and occludes said aorta, and wherein said occlusion results in hemostasis at said hemorrhage site below the inguinal area of the body; and
, wherein the tip of said air bladder comprises an elongate edge traversing the length of said bladder and generally equidistant from said base, wherein said elongated edge of the bladder is structured and dimensioned such that when said bladder is positioned over said aorta, said edge traverses said aorta to ensure occlusion of said aorta when said bladder is secured over the abdomen of said body and inflated, and,e. an air source operatively connected to said air bladder for inflation of said same. - View Dependent Claims (12, 13, 14, 15, 16)
