A junctional and truncal tourniquet and a 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 for securing a pressure applying device to a person so that blood vessel-occluding pressure can be applied. Areas of mating types of fastener material such as mating hook-bearing fastener material and loop pile fastener material are arranged on the device to enable a strap to be secured at various effective lengths to provide a wide range of adjustability. The device may include inflatable bladders, stays, and a chin support and may be wrapped around a patient's neck as a cervical support collar, or around the torso to occlude blood vessels proximal to an injury on a limb.
