Abstract:
Objective To develop a buckle tourniquet to facilitate further casualty treatment.Methods The requirements oftheater/field first aid of the PLA were analyzed.The existing spinning tourniquet was modified from the aspects of shorteningoperation time,controlling hemostatic pressure precisely,relieving tourniquet timely etc.The developed tourniquet was madeof engineering plastics and polyester webbing,and composed of a micro-regulation buckle,a main strap,a tightening band,atimer,a garrote,Velcro,a self-adhesive band,a garrote fixation clamp etc.Results The tourniquet had the operation timebeing 11.52 s,and avoided ischemic necrosis of tissues by automatic alarm in case of 1-h hemostasis for upper limbs or 1.5-hhemostasis for lower limbers.Conclusion The tourniquet gains advantages in low cost,high portability,easy operation,high efficiency and timing function,and thus meets the requirements for theater/field first aid.
