Description

[Technical field]

[0001] The invention belongs to the field of medical instruments, and particularly relates to a disposable three-cavity two-balloon tube for physical hemostasis of esophageal and gastric fundus varicose vein rupture and massive bleeding. [Background technology]

[0002] Ruptured esophageal varicose veins and massive bleeding are the most dangerous complications in patients with cirrhosis and portal hypertension. It has an acute onset, heavy bleeding, a dangerous course, and a very poor prognosis. The mortality rate of the first bleeding is as high as about 50%, the incidence of rebleeding within 6 weeks is 17%, and the incidence of rebleeding within 2 years is about 80%. Usually, when using hemostatic drugs for this type of bleeding, effective physical hemostasis methods must be taken in time, such as three-chamber two-balloon catheter compression hemostasis. Although this method has gradually been replaced by other non-surgical treatment methods, it is still the first choice for medical institutions. The three-chamber two-balloon tube currently used in clinical practice has many operational problems. For example, when injecting gas into the esophageal bag and gastric bag, a hemostatic forceps needs to be used to stop the repeated insertion and withdrawal of the injected gas, which leads to leakage and low efficiency, affecting the rescue time. In addition, since the existing catheters are made of rubber or natural latex, the hardness is not enough, resulting in the catheter and the esophageal bag and gastric bag not being able to comply with the insertion, and some people will be allergic to the soft rubber, which will delay the time for hemostasis and emergency treatment, delay the time for treatment and cause the death of the rescued person, as well as medical risks. Therefore, a disposable three-chamber two-balloon tube is proposed. [Summary of the invention]
