Problems solved by technology

However, there are the following disadvantages: 1. The distal aorta blocked by the balloon is completely isolated, and the organs and limbs that supply blood are in a state of severe ischemia, and even after resuscitation in the later stage, they will face "ischemia-reperfusion" injury; 2. 、Partial occlusion balloon (p-REBOA) will play a certain role in the blood supply of distal orga...

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 Shown, infused aortic occlusion double balloon, consisting of:

[0032] Main catheter 1, the first opening at its top is the main catheter infusion outlet 2, when the main catheter 1 is placed in the aortic lumen, the main catheter infusion outlet 2 is placed in the aortic cavity of the aortic arch , and the tail end leading to the body is the first tail end injection port 3 for perfusing liquid or blood;

[0033] The first balloon 4 is connected to the part below the top of the main catheter; when the main catheter 1 is placed in the aortic lumen, the first balloon 4 is located at the lower edge of the left subclavian artery to the celiac trunk in the upper half region between;

[0034] The first balloon injection catheter 5 is attached to the main catheter 1; the top of the first balloon injection catheter 5 communicates with the first ball...

Abstract

The present invention provides a perfusion type double balloon for aortic occlusion. The segmented double balloon is used to position the first balloon in the upper half region between the lower border of the left subclavian artery and the celiac trunk, which can Block the proximal aorta to minimize blood loss; the second balloon is positioned in the lower half of the area between the inferior edge of the renal artery and the bifurcation of the iliac artery, allowing blood loss to be isolated between the celiac trunk and the renal artery , to selectively perfuse important organs such as bilateral lower limbs; that is, to achieve selective fluid perfusion to non-injured related areas, and to solve the problem of organ and limb ischemia.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a perfusable double aortic blocking balloon, which is applied to hemostasis of trunk and important organ bleeding in battlefields and emergency situations. Background technique [0002] The current resuscitative aortic occlusion balloon (REBOA) is to place the balloon into the corresponding area of ​​the aorta to block the blood flow when the emergency department cannot completely stop bleeding from the trunk and abdominal organs, and strive for complete surgical hemostasis. time. However, there are the following disadvantages: 1. The distal aorta blocked by the balloon is completely isolated, and the organs and limbs that supply blood are in a state of severe ischemia, and even after resuscitation in the later stage, they will face "ischemia-reperfusion" injury; 2. 1. Partial occlusion of the balloon (p-REBOA) will play a certain role in the blood supply to the dist...
