Embodiment

[0029] Please refer to figure 1 , a double-balloon catheter with a pigtail, comprising: a pigtail 10 , a first balloon assembly 20 and a second balloon assembly 30 . The pigtail 10 includes a bent end 11 and an operating end 12 . The first balloon assembly 20 and the second balloon assembly 30 are sequentially disposed on the pigtail 10 along the direction from the curved end 11 to the operating end 12 . The pigtail 10 can be a single J pigtail or a double J pigtail. When a double J pigtail is used, the end for placing in the patient's body is the curved end 11 , and the end placed outside the patient's body is the operating end 12 .

[0030] The first balloon assembly 20 includes a first balloon 21 and a first catheter 22 . The pigtail tube 10 passes through the inside of the first balloon 21 , and the position where the pigtail tube 10 is in contact with the first balloon 21 is sealed and connected. The first conduit 22 is arranged side by side with the pigtail 10 and the...

Abstract

The invention discloses a dual-balloon catheter with a pigtail tube and belongs to the technical field of medical apparatuses and instruments. The dual-balloon catheter with the pigtail tube comprises the pigtail tube, a first balloon assembly and a second balloon assembly; the pigtail tube comprises a bending end and an operation end; the pigtail tube penetrates through the first balloon assembly and the second balloon assembly in the direction from the bending end to the operation end in sequence. According to the dual-balloon catheter with the pigtail tube, radiography and balloon placement are conducted in the same step, the operation time is shortened, the bleeding time is short, the bleeding amount is low, and the death rate of a patient is reduced; by arranging the two balloon assemblies, the blood flow can be blocked, the bleeding amount is reduced, and wounds can also be subjected to compression hemostasis.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a double-balloon catheter with a pigtail tube. Background technique [0002] At present, in the field of vascular surgery, endovascular treatment is almost the mainstream method for treating various vascular diseases. It has the advantages of less trauma and shorter hospital stay. Among them, aortic disease is one of the diseases with high risk and difficult treatment technology in the field of vascular surgery. First, due to the large diameter and high pressure of the aortoiliac artery itself, once it ruptures, the mortality rate is extremely high, which is also a great challenge for vascular surgeons. The key to the treatment of aortic rupture is to shorten the bleeding time and reduce the amount of bleeding as much as possible to save the patient's life. At present, in the treatment of ruptured aorta, for patients with hemodynamic instability, a balloon is placed in t...
