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 organs and limbs, but at the same time it will cause aggravated blood loss
[0004] However, after the balloon inflation is blocked, the position between the double balloons and the organs and limbs below the distal balloon cannot receive blood supply. Over time, the organs and limbs that supply blood are in a state of severe ischemia. Even late resuscitation will face "ischemia-reperfusion" injury

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 invention provides a perfusion-type aorta blocking double-balloon. The perfusion-type aorta blocking double-balloon has the advantages that by the sectional-type double-balloon, a first balloon islocated in an upper half portion region between the lower edge of the left subclavian artery and the celiac trunk, so that the near-end aorta can be blocked, and hemorrhage can be controlled to the greatest extent; a second balloon is located in a lower half portion region between the lower edge of the renal artery and the iliac artery bifurcation, so that hemorrhage between the celiac trunk andthe renal artery is blocked, and vital organs such as bilateral lower limbs are perfused selectively; selective liquid perfusion to related damage-free regions is realized, and the problem of ischemiaof visceral organs and limbs is solved.

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...
