Description

Compression tourniquet

The present invention relates to a pressurized tourniquet, especially a pressurized tourniquet that is easy to operate and can quickly pressurize and stop bleeding.

According to the customary tourniquet, it is usually a belt body sewn with hook and loop fasteners. The body is wound around the wound of the limbs of the human body close to the heart, and the hook and loop fastener is used to tighten and fix the body to achieve the purpose of hemostasis.

And this kind of tourniquet, which is simply fastened and fixed by hook and loop fasteners, may provide effective hemostasis for smaller wounds, but it cannot exert its effect in the case of larger wounds or heavy bleeding. .

For this reason, in recent years, the industry has developed a "tactical tourniquet" that can be used for larger wounds or bleeding, as disclosed in China's Patent Publication No. M551906. The tactical tourniquet is mainly composed of a plate body, a rotating rod, a first belt body and a second belt body. Wherein, the two ends of the first belt body and the second belt body respectively pass through the piercing parts of the two ends of the plate body, and are wound through the first fixing seam and the second fixing seam on the rotating rod, and then the other ends are respectively Connect or pass through a connecting fastener to adjust the length between the two straps. The first strap can be wound between the bleeding part of the human body and the heart, and the first strap can be tightened to achieve the initial pressure to stop the bleeding. The first belt body and the second belt body are wound on the rotary rod by the rotating rotary rod, and a movable fixing member is used to fix the position of the rotary rod to restrict the rotation of the rotary rod and provide further pressure to stop bleeding.

After investigation, the tactical tourniquet has been manufactured and assembled. The first belt One end of the body and the second belt body needs to repeatedly pass through the perforation slits on the two ends of the plate body, and then pass through the first fixing seam and the second fixing seam on the rotating rod of the rotating rod, and the other end of the belt body It is necessary to pass through the connecting seam on the connecting buckle and fix the first belt body with sewing before the assembly can be completed. Therefore, it is not only complicated and inconvenient to assemble, but also the first belt body and the second belt body are in a twisted state, which seriously affects the smoothness of pulling, especially when the patient’s limbs are bleeding profusely. One belt or the second belt is stuck and cannot be tightened smoothly, causing the patient to lose blood continuously and even life-threatening. Furthermore, when the movable fixing member is tightening the rotating rod to wind the first belt body and the second belt body on it, the rotating rod cannot be effectively fixed immediately, which may easily cause the rotating rod to rotate, causing the first belt to rotate. The body and the second belt body are released and lose the effect of further pressure to stop bleeding. It can be seen that the tactical tourniquet has many shortcomings in manufacturing, assembly and use, and these shortcomings are related to the life safety of patients with heavy bleeding, and they need to be effectively improved.

The present invention is to provide a compression tourniquet which is easy to operate and can quickly pressurize the wound to stop bleeding.
