Description

Technical Field

[0001] The utility model relates to the technical field of digestive endoscopic treatment, and more specifically to an endoscopically visible three-cavity two-balloon tube. Background Art

[0002] Esophageal varices are usually caused by liver scar tissue (cirrhosis) caused by liver disease. Blood flow to the liver is blocked, and when blood begins to flow back, the large vein responsible for transporting blood to the liver (portal vein) will be under greater pressure. This condition is called portal hypertension. Portal hypertension forces blood to find other pathways through smaller veins, such as the veins at the lowest part of the esophagus. These thin-walled veins will expand as the blood increases, and sometimes these veins will rupture and bleed.

[0003] When considering the rupture and bleeding of esophageal varicose veins at the gastric fundus, emergency endoscopic hemostasis can be considered. However, some patients may not be able to receive endoscopic ligation and sclerosing agent treatments due to various reasons. Therefore, the traditional three-chamber two-balloon tube is used as an alternative. However, the traditional three-chamber two-balloon tube stops bleeding by compressing the gastric fundus and esophagus, and the compression hemostasis effect cannot be clearly seen. The compression effect can only be judged by the change in hemoglobin and the color of the drainage tube. Therefore, the utility model provides an endoscopically visible three-chamber two-balloon tube. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide an endoscopically visible three-chamber two-balloon tube, which solves the problem that the traditional three-chamber two-balloon tube in the prior art stops bleeding by compressing the gastric fundus and esophagus, and the compression hemostasis effect cannot be clearly seen, and the compression effect can only be judged by the change of hemoglobin and the color of the drainage tube.

[0006] 2. Technical solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] An endoscopically visible three-chamber two-balloon tube comprises a medical silicone tube, the outer circumference of which is provided with an annular balloon and a disc-shaped balloon, and the outer circumference of which is also provided with a first inflation port and a second inflation port;

[0009] The medical silicone tube is provided with cavity one, cavity two and cavity three, the inflation port one is connected with the annular balloon through cavity two, the inflation port two is connected with the disc-shaped balloon through cavity three, and the outer circumferential surfaces of the inflation port one and the inflation port two are both provided with blocking mechanisms.

[0010] Furthermore, the sealing mechanism includes a connecting piece and a roller. The connecting piece is sleeved and fixedly connected to the outer circumferential surface of the second inflation port. A limiting groove is provided on the inner wall of the connecting piece. A roller is movably connected in the limiting groove. The outer circumferential surface of the roller is in contact with the second inflation port.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) In this scheme, gas is injected from inflation port 2 and inflation port 1 respectively. The gas enters the disc-shaped balloon and the annular balloon through cavity 3 and cavity 2 respectively, thereby causing the disc-shaped balloon and the annular balloon to expand. The expanded disc-shaped balloon is used to compress the gastric fundus, and the expanded annular balloon is used to compress the esophagus. This scheme can be used in the state of endotracheal intubation, combined with ultra-gastroscopy to treat bleeding caused by rupture of esophageal veins in the gastric fundus, and the hemostasis effect can be observed in detail, thereby improving the success rate of hemostasis and providing an opportunity for subsequent further treatment.

[0018] (2) The present scheme is provided with a blocking mechanism. After the personnel inject gas from the second inflation port and the first inflation port respectively, before withdrawing the syringe, the personnel push the roller. The roller can move horizontally along the limit groove and can also move downward. The roller moving downward can squeeze the second inflation port or the first inflation port, thereby timely blocking the second inflation port or the first inflation port to prevent gas backflow leakage, affecting the hemostasis effect, and also facilitating the personnel to operate.

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] Example

[0026] like Figure 1-3 As shown, an endoscopically visible three-chamber two-balloon tube comprises a medical silicone tube 1, an annular balloon 2 and a disc-shaped balloon 3 are arranged on the outer circumference of the medical silicone tube 1, and an inflation port 1 4 and an inflation port 2 5 are also arranged on the outer circumference of the medical silicone tube 1;

[0027] The medical silicone tube 1 is provided with cavity 11, cavity 2 12 and cavity 3 13, the inflation port 1 4 is connected with the annular balloon 2 through cavity 2 12, the inflation port 2 5 is connected with the disc-shaped balloon 3 through cavity 3 13, and the outer circumferential surfaces of the inflation port 1 4 and the inflation port 2 5 are both provided with a blocking mechanism 6.

[0028] The medical silicone tube 1 has an inner diameter of 11 mm, an outer diameter of 14 mm, and a length of 50 cm. The disc-shaped balloon 3 is arranged 2 cm from the end, and the annular balloon 2 is arranged 2-15 cm from the end.

[0029] When in use, gas is injected from inflation port two 5 and inflation port one 4 respectively, and the gas enters the disc-shaped balloon 3 and the annular balloon 2 through cavity three 13 and cavity two 12 respectively, thereby causing the disc-shaped balloon 3 and the annular balloon 2 to expand. The expanded disc-shaped balloon 3 is used to compress the gastric fundus, and the expanded annular balloon 2 is used to compress the esophagus. It can be used for the treatment of ruptured esophageal veins and bleeding in the gastric fundus in the state of endotracheal intubation in combination with super gastroscopy, which can observe the hemostatic effect in detail, improve the success rate of hemostasis, and provide an opportunity for subsequent further treatment.

[0030] like Figure 1 and 3 As shown, the blocking mechanism 6 includes a connecting member 61 and a roller 62. The connecting member 61 is sleeved and fixedly connected to the outer circumferential surface of the inflation port 2 5. The inner wall of the connecting member 61 is provided with a limiting groove 611. The roller 62 is movably connected in the limiting groove 611. The outer circumferential surface of the roller 62 is in contact with the inflation port 2 5.

[0031] When in use, after a person injects gas from inflation port 2 5 and inflation port 1 4 respectively, before withdrawing the syringe, the person pushes roller 62, and roller 62 can move horizontally along limit groove 611 and can also move downward. The downward moving roller 62 can squeeze inflation port 2 5 or inflation port 1 4, thereby timely blocking inflation port 2 5 or inflation port 1 4 to prevent gas from backflowing and leaking, affecting the hemostasis effect, and also facilitating the operation of the person.

[0032] like Figure 1-2 As shown, a fixing ring 14 is fixedly connected to the outer circumferential surface of the medical silicone tube 1 .

[0033] When in use, a traction device can be installed on the fixing ring 14 to pull the medical silicone tube 1.

[0034] like Figure 1 As shown, the outer circumferential surfaces of the inflation port 1 4 and the inflation port 2 5 are both provided with labels 41 .

[0035] When in use, it is convenient for personnel to quickly inflate the balloons corresponding to the inflation port 1 4 and the inflation port 2 5 respectively. In actual operation, gas is first injected into the disc-shaped balloon 3 from the inflation port 2 5, and then gas is injected into the annular balloon 2 from the inflation port 1 4 to avoid operational errors by personnel.

[0036] like Figure 2 As shown, the upper and lower ends of the cavity 11 are connected.

[0037] When in use, after one end of the medical silicone tube 1 is inserted into the stomach, gastric juice can be extracted through the cavity 11 to determine whether the medical silicone tube 1 is placed in place.

[0038] In summary, the specific working process of this scheme is as follows: first, gas is injected from the second inflation port 5 and the first inflation port 4, and the gas enters the disc-shaped balloon 3 and the annular balloon 2 through the third cavity 13 and the second cavity 12, respectively, so that the disc-shaped balloon 3 and the annular balloon 2 are expanded, and the expanded disc-shaped balloon 3 is used to compress the gastric fundus, and the expanded annular balloon 2 is used to compress the esophagus. It can be used in the state of endotracheal intubation, combined with super gastroscopy to treat ruptured bleeding of esophageal veins in the gastric fundus, and the hemostasis effect can be observed in detail, thereby improving the success rate of hemostasis and providing opportunities for subsequent further treatment;

[0039] Among them, after the personnel inject gas from the inflation port 2 5 and the inflation port 1 4 respectively, before withdrawing the syringe, the roller 62 is pushed. The roller 62 moves horizontally along the limiting groove 611 and can move downward at the same time. The downward moving roller 62 can squeeze the inflation port 2 5 or the inflation port 1 4, thereby timely blocking the inflation port 2 5 or the inflation port 1 4 to prevent the gas from flowing back and leaking, affecting the hemostasis effect, and also facilitating the operation of the personnel.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
