It should be noted that the same tourniquet is used for the two ways of tying the lower uterine segment by the tourniquet, and the same hemostasis effect is achieved. Which is used specifically to temporarily stop bleeding from major uterine bleeding, as the case may be. It should be noted that the one end of the needle-like portion is blunt because the connecting portion is located between the band body 120 and the skin after the bundling is completed, the skin is not easily damaged due to the blunt setting, and the needle-like portion does not affect the connecting portion from penetrating the wide ligament of uterus.

Alternatively, as shown in fig. 3, the hard connecting member 110 is a cylinder 111, one end of the cylinder 111 is provided with a mounting hole, and the belt body 120 is fixedly connected with the cylinder 111 through the mounting hole.

When the artery of the limbs of the patient bleeds, the tourniquet is needed for temporary hemostasis. Those skilled in the art will appreciate that the tourniquet should be strapped around the upper limb at the upper 1/3 of the upper arm and the mid-lower 1/3 junction of the thigh of the lower limb. When the tourniquet is used, the strap body 120 is encircled at the position, the cylinder 111 penetrates through the ring 130, the ring 130 is pressed by one hand, the strap body 120 is tightened by the other hand to be connected with one end of the cylinder 111, the tightness degree of the strap is folded back after hemostasis, the cylinder 111 meets the through holes 1221 after folding back, and the cylinder 111 is placed in parallel to the skin after penetrating through the through hole 1221 closest to the cylinder 111.
