Description
Technical Field
The invention belongs to the field of medical equipment, and particularly relates to a perfusion type aortic blocking double balloon which is applied to hemostasis of trunk and important viscera hemorrhage under battlefield and emergency conditions.
Background
The current resuscitation aorta occlusion saccule (REBOA) is placed in the corresponding region of the aorta to block blood flow under the condition that the emergency can not completely stop bleeding of the trunk and abdominal organs, so that time is striven for complete operation hemostasis. There are several disadvantages: 1. the far-end aorta blocked by the saccule is completely isolated, and the viscera and limbs of the aorta are in a serious ischemia state, and the aorta is also subjected to ischemia reperfusion injury even after later resuscitation; 2. the partial occlusion balloon (p-REBOA) can have a role in the blood supply to the distal viscera and limbs, but at the same time can cause a hazard of exacerbating blood loss.
Chinese patent application CN106924862a discloses an aortic intracavity dual-level balloon occlusion pressurized infusion system comprising a main catheter, an aortic arch balloon and an aortic distal balloon, and a channel and an injection port for injecting water or gas into the balloon. This patent application, while providing a dual balloon device within the aortic lumen, emphasizes "aortic arch pressurized perfusion" achieved by "transfemoral catheterization," thus innovatively designed and applied to resuscitation of ischemic cardiac arrest CECA). During the occurrence of the sudden cardiac arrest with blood loss, the aortic arch pressurization perfusion is realized by a tube arrangement mode with the direction of aortic blood flow reversed, the reverse pressurization blood flow can be formed in the aortic arch, and the balloon inflation of the aortic arch part temporarily blocks the infusion liquid from running off to the distal end of the aorta, so that the coronary artery can be opened in the shortest time, the myocardial perfusion is improved, the power for the elevation of the blood pressure of the aortic arch part is generated, the cerebral perfusion is improved, and finally, the resuscitation effect of the sudden cardiac arrest with blood loss is improved. Before and after the autonomous circulation is established, the system can selectively inflate and block the aortic cavity in the aortic cavity at the aortic arch part and the far-end bifurcation part of the abdominal aorta respectively, and the blocking part and the time can also select different levels of sacculus emergency inflation blocking according to the CPP recovery condition and the bleeding part.
However, after the balloon inflation is blocked, blood supply to the viscera, limbs and the like at the position between the two balloons and under the far-end balloon cannot be obtained, and the viscera and the limbs which supply blood are in a severe ischemia state for a long time, and even in later resuscitation, the 'ischemia reperfusion' injury can be faced.
