This utility model provides a high-efficiency tourniquet, relating to the field of tourniquet technology. It includes a tourniquet body, a connecting collar, a first connecting member, a second connecting member, a vertical rod, a first auxiliary member, a second auxiliary member, and a third auxiliary member. By rotating the vertical rod, the first connecting member is coiled around its outer surface. As the first connecting member moves, the first auxiliary member moves closer to the vertical rod. This causes the third auxiliary member to shift, separating the toothed part from the blocking ring. At this point, the tourniquet body, located between the toothed part and the blocking ring, can be pulled, causing it to adhere tightly to the patient's wound. Then, the vertical rod can be released, eliminating the external tension on the third auxiliary member. This causes the toothed part to move back towards the blocking ring, thus preventing further movement of the tourniquet body and effectively stopping bleeding from the wound.

The present application relates to the technical field of tourniquet, in particular to a multifunctional tourniquet for controlling bleeding in the junctional area under field conditions, comprising a tourniquet assembly. The present application ingeniously locks the tourniquet body and the human body limb by setting two groups of anti-skid mechanisms comprising fixing belts, positioning plates, clamping blocks and device sleeves. When the clamping blocks are precisely inserted into the clamping grooves on both sides of the device sleeve under the action of the spring restoring force, a rigid closed structure surrounding the limb is formed. This structure can effectively resist the axial shear force generated by the movement of the wounded, the change of body position or the contraction of limb muscles. At the same time, the linkage system composed of the device sleeve and the positioning belt can disperse the local stress. Even if there is sweat or blood on the surface to cause lubrication, the mechanical self-locking design of the multi-point clamping can also prevent the overall tourniquet from sliding or twisting, so as to maintain constant ring pressure and position in the dynamic jolt environment of field evacuation, greatly reducing the risk of tourniquet failure and secondary bleeding caused by instrument displacement.
