Devices and methods are disclosed for achieving hemostasis in patients who have received skin-penetrating wounds to the periphery, including the head, arms, and legs. Such haemostatic packing devices and methods are especially useful in the emergency, trauma surgery, or military setting. The devices utilize fluid impermeable barriers surrounded by exterior dams and pressure to achieve tamponade and hemostasis, primarily by exertion of force to hold the dams against the skin surrounding a wound. The devices are capable of serving as carriers for thrombogenic, antimicrobial or antipathogenic agents. The devices do not require the use of adhesives to work as they are attached to the patient using mechanical locking devices. Peripheral haemostatic packing devices include optional adhesive hemostatic barriers to attach at least a portion of the device to the skin or to assist with initial coupling of a hold-down strap to another strap using a more secure mechanical lock. The peripheral hemostatic packing system does not completely surround the extremity having the wound and therefore do not cause a tourniquet effect. The peripheral hemostatic packing system preferably is held against the skin surrounding a wound by a force that is generally unidirectional and substantially perpendicular to the plane in which the skin of the wound resides.
