Description

Technical Field

[0001] The utility model relates to the technical field of tourniquets, in particular to an artery compression tourniquet. Background Art

[0002] After the patient's arterial puncture, a tourniquet is needed to stop the bleeding. Currently, the patient or his family members press the puncture point with a cotton swab. Since it is arterial compression to stop bleeding, the pressing time is relatively long. Manual pressure can easily cause the pressing position to shift, and finger pressure cannot maintain the same pressure. When the pressure is too high, pressure sores are likely to occur. When the pressure is too low, the pressing time is longer.

[0003] After searching, the specification of patent application number CN217525265U discloses an arterial compression tourniquet, including a fixing plate, a fixing belt and a compression hemostatic ball. Both ends of the fixing belt are connected to the fixing plate. The fixing belt is provided with a locking device to fix the fixing plate on the arterial wound. A compression hemostatic ball is provided on the fixing plate. The hemostatic ball has a certain elasticity. One side is fixed to the fixing plate, and the other side of the spherical surface squeezes the arterial hemostatic point. The arterial hemostatic point is concentratedly squeezed by fixing the spherical vertex of the compression hemostatic ball, which can not only achieve the purpose of wound compression hemostasis, but also avoid excessive pressure on the wound edge tissue.

[0004] However, due to the setting of the compression hemostatic ball, it is necessary to replace compression hemostatic balls of different sizes according to the compression hemostasis of different parts, which has a high cost of use, and the pressure of the compression hemostatic ball on the wound is fixed, and the compression force cannot be freely adjusted, resulting in poor hemostatic effect and low applicability. At the same time, due to the use of fixing belts and locking devices on the arm, the thickness of the arms of different patients is different. Therefore, patients with too thick arms will be subjected to greater compression and discomfort during use, and patients with too thin arms will easily have the fixing belt loosened during use, resulting in poor fixation effect.

[0005] Therefore, we proposed an arterial compression tourniquet. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides an artery compression tourniquet, which solves the problems of poor hemostatic effect and poor fixing effect of the prior device.
