Materials: polyester ABS Color: black Size: 3.8*95cm Equipped with a precision rotary compression knob, this product achieves uniform and controllable compression based on mechanical transmission principles. The pressure increases linearly during rotation, allowing medical staff to precisely control the hemostatic force and avoid secondary damage to limb tissues caused by excessive compression. Compared with traditional tourniquets, it improves compression efficiency by 50%, enabling effective hemostasis in only 10-15 seconds, which perfectly meets the urgent needs of emergency scenarios.
