[0002] The incidence of limb injuries in all wars at home and abroad has exceeded half of the total number of casualties. In a war environment, severe fractures and injuries to the limbs are often not treated promptly and quickly, resulting in limb disability or even death on the spot. In addition, some of the wounded often have to pay the price of amputation to save their lives after receiving first aid on the spot, resulting in serious functional disorders and disabilities. Severe fractures and injuries to the limbs not only cause a large number of combat casualties, but also lead to the loss of the wounded's ability to live after the war.

[0003] At present, the first aid bandage equipment used in the battlefield is a triangular bandage (a triangular bandage equipment), which is an important multi-purpose first aid equipment in the battlefield. It can be used for bandaging and fixing multiple parts. The triangular bandage can be used to fix wooden sticks and the like for strangulation and hemostasis, but the actual use effect is limited and there are many shortcomings. New first aid equipment also includes elastic bandages and roll splints, which have good fixing and bandaging effects, but the operation time is long and often cannot be completed in the battlefield environment.
