Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more particularly to a rapid hemostatic balloon catheter for ruptured bleeding of the inferior vena cava. Background Art

[0002] Trauma-induced rupture of the retrohepatic inferior vena cava causes rapid and heavy bleeding, which is life-threatening. Rapid and effective hemostasis is the key to saving the lives of the wounded. However, currently more effective treatment measures, such as inferior vena cava repair, are usually difficult to implement successfully in emergency situations. First, there is a shortage of professional surgical equipment and personnel in emergency situations. Second, blood in the surgical area cannot be cleared in time during heavy bleeding, and the visual field is obscured, resulting in the inability to fully expose the injured area, making it difficult to perform rapid and effective temporary hemostasis under the current circumstances. Even in the case of severe abdominal trauma combined with the inferior vena cava, which is seen in daily life, the mortality rate after treatment is still extremely high.

[0003] Therefore, how to provide a rapid hemostasis balloon catheter for inferior vena cava rupture bleeding that can achieve rapid hemostasis and reduce mortality is one of the technical problems that urgently need to be solved in the art. Summary of the invention

[0004] In view of this, the present invention provides a rapid hemostatic balloon catheter for ruptured bleeding of the inferior vena cava, the purpose of which is to solve the above-mentioned shortcomings.
