The rugged and versatile LSP Half Back is a unique vertical extrication device that combines the capabilities of a full body harness with the ability to immobilize the patient if cervical/spinal trauma is suspected. The LSP Half Back consists of two components: a rugged, padded full body harness and a removable aluminum back stay with head immobilizer. This unique design allows for rapid immobilization and vertical extrication of a patient in a confined or elevated space, including but not limited to high rise buildings, storage tanks, ships and automobiles.
