传统止血带通常用绷带紧系伤口所在的肢体，压迫血管达到止血效果，这种急救场合首选的止血方法会伴随剧烈疼痛。而神经止血带不需绷带对血管进行物理挤压，医生将手持装置轻按皮肤上，刺激大脑与主要器官间传递信息的迷走神经，迷走神经再将信号传到脾脏，脾脏内的神经细胞向血小板释放一种化学物质，让血小板随时做好准备，在身体受伤时发挥凝血功能止血。
Traditional tourniquets usually use bandages to fasten the limbs where the wound is located and compress the blood vessels to achieve the hemostasis effect. The first choice hemostasis method in this emergency situation will be accompanied by severe pain. The nerve tourniquet does not need bandages to compress the blood vessels physically. The doctor gently presses the hand-held device on the skin to stimulate the vagus nerve, which transmits information between the brain and the main organs. The vagus nerve then transmits the signal to the spleen. The nerve cells in the spleen release a chemical substance to the platelets, so that the platelets are ready at any time to play the coagulation function to stop bleeding when the body is injured.
