Abstract

The invention relates to a self-locking body-surface-wound hemostat which is disposable or can be used many times. The self-locking rapid hemostat comprises a clamping part, a self-locking part and an unlocking part, wherein the clamping part is used for rapidly clamping and squeezing the injured skin on the body surface and rapidly stopping bleeding, the self-locking part is of a single-rotation-direction stopping ratchet wheel structure and brings convenience to medical staff to rapidly carry out clamping and meshing, and the unlocking part is used for easily detaching the self-locking rapid hemostat in the rescue process and prevents the injured surface from further expanding the injury. The self-locking rapid hemostat can also be applied to skin tearing injuries of the thorax and abdomen part and the limbs in the battlefield rescue process, improves the hemostatic effect with the help of hemostatic dressing, reduces the possibility of infection, prolongs the lives of the wounded, wins precious rescue time for subsequent treatment, and can serve as a special first-aid hemostatic instrument. The self-locking rapid hemostat is reasonable in structure, is flexible and convenient to operate, is easy to apply, and is mainly applied to the skin tearing injuries of the thorax and abdomen part and the limbs and wound bleeding in the first-aid process.

Description

technical field [0001] The invention relates to a self-locking rapid hemostasis device, which belongs to the technical field of medical instruments. Background technique [0002] Traditional large limb arterial and venous bleeding, and for the convenience of transporting the wounded, the tourniquet method is often used. The use of the tourniquet should strictly follow the essentials of moderation. If the tourniquet is tied too tightly and the time is too long, it can cause soft tissue compression and necrosis, and the limbs will be far away. If the tie is not tight, there will still be blood flow at the distal end of the artery, while the venous return is completely blocked, which will cause more bleeding from the wound. [0003] The tourniquet method can effectively stop bleeding from the extremities. However, the tissue damage after use may cause or aggravate extremity necrosis, acute renal insufficiency and other complications. [0004] Therefore, in order to explore fa...
