Abstract

The invention relates to the field of medical instruments, in particular to a hemostatic device for prehospital incompressible trunk bleeding, which comprises a body, a first air bag, a second air bagand a third air bag; the first air bag, the second air bag and the third air bag are detachably installed on the inner side of the body; and air inflow of the first air bag, the second air bag and the third air bag is independently controlled. According to the invention, three independent air bags are arranged, and act on an abdominal aorta, a left iliac general artery and a right iliac general artery respectively, so that when only the left iliac general artery or the right iliac general artery is injured and loses blood, the second air bag or the third air bag can be used, the compression area can be reduced, and ischemic injury to other blood vessels, tissues, organs and opposite lower limbs around a bleeding plane is avoided. Due to the fact that the first air bag, the second air bagand the third air bag are detachably installed on the body, when one air bag is damaged, the other air bag can be installed at the position where the damaged air bag is damaged, and the condition thathemostasis can be effectively achieved in time is guaranteed.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a hemostatic device for pre-hospital incompressible trunk bleeding. Background technique [0002] Noncompressible trunk bleeding refers to a type of bleeding secondary to noncompressible trunk injuries (chest, abdomen, and pelvic trauma), accompanied by systolic blood pressure less than 90 mmHg, and cannot be controlled by conventional mechanical compression methods such as extremity tourniquets. [0003] Sharp injuries or high-energy trauma (explosion injuries, car accidents, etc.) can often cause blood vessels to rupture and cause massive bleeding. If the treatment is not timely, excessive blood loss will seriously threaten the lives of the wounded. [0004] At present, the hemostatic devices and strategies for pre-hospital trunk bleeding mainly include: (A) hemostatic sponge: the cellulose sponge coated with chitosan is injected into the wound cavity, and hemostasis can be ac...
