SELF-STABILIZING PORTABLE PNEUMATIC ABDOMINAL AORTIC TOURNIQUET WITH RATCHETING TENSIONER

摘要

A self-stabilizing pneumatic abdominal aortic tourniquet that utilizes a semi-ridge retaining strap, a ratcheting retaining buckle, and an elastic guide cord on the lower penetrating end of a wedge-shaped bladder. A rigid baseplate is supported by a waist belt having a width identical with the waist belt so that the baseplate provides a stable base for positioning the bladder over a selected area of the patient's abdomen. The air bladder is affixed to the underside of the baseplate, which is initially kept in a deflated condition collapsed against the baseplate, and includes an elastic cord, such as a shock cord, configured to bias the tip of the wedge or “V” shaped bladder in the middle of the baseplate. An air source connected to the air bladder causes inflation and penetration of the lower edge of the bladder into the patient's abdomen thereby causing aorta occlusion.
