Device for control of hemorrhage including stabilized point pressure device

A junctional and truncal tourniquet and hip-girdling pelvic sling device for maintaining a desired amount of tension surrounding a person's hips and pelvis to securely support and stabilize a pelvis that has been fractured and to secure a pressure applying device with a preferred amount of tension so that blood vessel-occluding pressure can be applied to stem hemorrhaging. The device may be wrapped around a patient's torso and may include inflatable pressure application bladders useful to occlude blood vessels proximal to an injury on a limb.
