由于战术战伤救治(TCCC)理念在美军各军种得到有效推广,特别是CAT旋压式止血带的广泛应用，美军在伊拉克和阿富汗战争中由四肢出血造成的死亡所占比例明显降低。相对而言，由躯干部位或交界部位出血造成的死亡比例不断增大，尤其是腹股沟、腋窝等交界部位的出血近年来引起外军的高度重视美军交界部位止血带-SAM（SJT）是美军战伤救护中交界部位止血带的一种，主要是利用充气加压的方式止血，用于一般止血带无效的交界部位伤口止血，亦可用于骨盆骨折的简易固定。
As the concept of tactical combat wound treatment (TCCC) has been effectively promoted in various military units of the United States, especially the wide application of CAT spinning tourniquet, the proportion of deaths caused by hemorrhage of limbs in the wars in Iraq and Afghanistan has been significantly reduced. Relatively speaking, the proportion of death caused by bleeding at trunk or junction is increasing, especially at the junction of groin and axilla. In recent years, foreign troops attach great importance to the American military junction tourniquet-SAM (SJT), which is a kind of tourniquet at the junction of the American army's war wound rescue, mainly using pneumatic compression. The method of hemostasis can be used for wound hemostasis at the junction where the tourniquet is ineffective. It can also be used for simple fixation of pelvic fracture.
近期美军研究数据表明，交界部位出血占战伤可预防死亡的20%，迅速、有效的止血措施有助于伤员的存活。研究表明，简易爆保定平面设计培训 收费岛模具 挡土墙模具 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网炸装置导致美军下肢受伤截肢有24%与骨盆骨折相关。
Recent U.S. military research data show that border bleeding accounts for 20% of preventable deaths from war injuries. Rapid and effective hemostasis measures help survive the wounded. Studies have shown that 24% of amputations caused by improvised explosive devices are associated with pelvic fractures
