Description

Technical Field

[0001] This utility model relates to the field of three-lumen two-balloon tube technology, specifically an improved novel three-lumen two-balloon tube. Background Technology

[0002] The three-lumen two-balloon tube is an emergency hemostatic medical device specifically designed for acute esophageal and gastric variceal rupture and massive bleeding. Its core design consists of three independent lumens and two inflatable balloons. The gastric lumen is connected to the stomach for aspiration of gastric contents or injection of medication. The esophageal lumen is connected to the esophageal balloon, which, when inflated, can exert local pressure on the lower esophagus. The gastric balloon lumen is connected to the pear-shaped balloon at the bottom, which is fixed to the cardia by traction to form physical compression for hemostasis. The two balloons work together to block blood flow from the esophageal veins at the gastric fundus, while the distal gastric tube can dynamically monitor the bleeding.

[0003] Existing three-lumen two-balloon tubes need to be inserted into the patient's body through the nasal cavity during use. However, the radii of the esophageal and gastric balloons are relatively large, which causes friction with the patient's nasal cavity and esophagus during insertion, resulting in pain and discomfort. There is no device to reduce the diameter of the balloons. Therefore, an improved new type of three-lumen two-balloon tube is needed to meet people's needs. Utility Model Content

[0004] The purpose of this invention is to provide an improved novel three-lumen two-balloon tube to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an improved novel three-lumen two-balloon tube, comprising an external catheter, a rotating ring rotatably mounted at one end of the external catheter, a flexible guidewire mounted at one end of the rotating ring, a shrinking tube mounted on the side of the flexible guidewire, a threaded groove adapted to the flexible guidewire being formed inside the shrinking tube, a tube removal groove mounted at one end of the shrinking tube, and a three-lumen two-balloon tube body mounted at one end of the tube removal groove.

[0006] Preferably, an esophageal balloon tube is installed at one end of the three-lumen two-balloon tube body, and a gastric balloon tube is installed at the other end of the three-lumen two-balloon tube body. Pressure gauges are installed on the sides of both the esophageal balloon tube and the gastric balloon tube.

[0007] Preferably, one end of the three-lumen two-balloon tube body is provided with an esophageal balloon, and the other end of the esophageal balloon is provided with a gastrointestinal balloon.

[0008] Preferably, one end of the externally attached conduit is provided with an arc-shaped guide tube, and symmetrical connectors are installed on the side of the arc-shaped guide tube.

[0009] Preferably, a sealing sleeve is installed at the top of the three-lumen two-balloon tube body, the esophageal balloon tube is adapted to the esophageal balloon, and the gastric balloon tube is adapted to the gastric balloon.

[0010] Preferably, the flexible guidewire is threadedly connected to the sac tube, which is adapted to the esophageal and gastric sacs.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] (1) This utility model reduces the diameter of the esophageal and gastric balloons on the side of the three-lumen two-balloon tube by setting a shrinking balloon tube and a threaded groove. By opening the groove at one end of the shrinking balloon tube, the shrinking balloon tube is fitted onto the esophageal and gastric balloons to prevent them from expanding. An external catheter is fitted onto the outside of the shrinking balloon tube. When in use, the external catheter drives the three-lumen two-balloon tube body into the patient's body. Rotating the flexible guide ribbon causes the rotating ring to rotate, thereby moving the shrinking balloon tube within the external catheter. The continuous movement of the shrinking balloon tube exposes the esophageal and gastric balloons, facilitating subsequent inflation support. The shrinking balloon tube reduces the radius of the esophageal and gastric balloons, making the patient more comfortable when placing the three-lumen two-balloon tube body.

[0013] (2) By setting up an arc-shaped guide tube and a connector, when inserting the external catheter, one end of the arc-shaped guide tube is first inserted into the patient's nasal cavity. The connector helps to prevent the arc-shaped guide tube from completely entering the nasal cavity and provides some support to the surrounding area of ​​the nasal cavity. Medical staff can apply paraffin oil to the surface of the arc-shaped guide tube to help push the external catheter in better, which improves the comfort when placing the three-lumen two-balloon tube.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5This utility model provides a technical solution: an improved novel three-lumen two-balloon tube, comprising an external catheter 1, a rotating ring 2 rotatably mounted at one end of the external catheter 1, a flexible guidewire 3 mounted at one end of the rotating ring 2, a shrinking balloon tube 4 mounted on the side of the flexible guidewire 3, a threaded groove 5 adapted to the flexible guidewire 3 inside the shrinking balloon tube 4, a tube removal groove 6 mounted at one end of the shrinking balloon tube 4, a three-lumen two-balloon tube body 7 mounted at one end of the tube removal groove 6, an esophageal balloon 12 at one end of the three-lumen two-balloon tube body 7, a gastrointestinal balloon 13 at one end of the esophageal balloon 12, and an arc-shaped [feature] at one end of the external catheter 1. The guide tube 14 has symmetrical connectors 15 installed on its side. A sealing sleeve 11 is installed on the top of the three-lumen two-balloon tube body 7. The esophageal balloon tube 8 is adapted to the esophageal balloon 12, and the gastric balloon tube 9 is adapted to the gastric balloon 13. The flexible guide wire 3 is threaded to the shrinking balloon 4, which is adapted to the esophageal balloon 12 and the gastric balloon 13. When the three-lumen two-balloon tube body 7 needs to be used, the esophageal balloon 12 and the gastric balloon 13 on the three-lumen two-balloon tube body 7 are first reduced in diameter by mechanical compression or other means. Then, the shrinking balloon 4 is removed, and one end of the tube groove 6 is bent... The esophageal balloon 12 and gastric balloon 13, after being reduced in diameter, are covered by the balloon tube 4 to prevent dispersion. Paraffin oil is evenly coated on the surfaces of the external catheter 1, the balloon tube 4, and the three-lumen two-balloon tube body 7 to ensure lubrication during insertion. After the balloon tube 4 is installed, one end of the external catheter 1 is inserted from the bottom of the three-lumen two-balloon tube body 7. The flexible guide wire 3 is passed through the threaded groove 5 inside the balloon tube 4 and rotated to hold the balloon tube 4 in the appropriate position. When installing the three-lumen two-balloon tube body 7, the arc-shaped guide tube 14 is first removed, and one end of the arc-shaped guide tube 14 is placed on the affected area. The external catheter 1 is inserted into the patient's nasal cavity. The connector 15 is used to block the flow and prevent the arc-shaped guide tube 14 from slipping. The external catheter 1 is then inserted through the opening of the arc-shaped guide tube 14. The esophageal balloon 12 and gastric balloon 13 inside the three-lumen two-balloon tube body 7 are narrowed, which reduces friction with the patient's esophagus when the external catheter 1 is inserted, thereby improving the patient's comfort. After insertion, the flexible guide wire 3 is rotated to drive the rotating ring 2 to rotate. Through the threads in the threaded groove 5, the shrinking balloon tube 4 can slide to a certain extent. Then, the external catheter 1 is pulled out along with the shrinking balloon tube 4, completing the placement of the three-lumen two-balloon tube body 7.

[0024] Example 2: As Figure 2 and 3 As shown, an esophageal balloon tube 8 is installed at one end of the three-lumen two-balloon tube body 7, and a gastric balloon tube 9 is installed at the other end of the three-lumen two-balloon tube body 7. Pressure gauges 10 are installed on the sides of both the esophageal balloon tube 8 and the gastric balloon tube 9. Inflation is made into the three-lumen two-balloon tube body 7 through the esophageal balloon tube 8 and the gastric balloon tube 9. Medical staff can observe the reading on the pressure gauges 10 to judge the pressure of the balloon, prevent mucosal damage, and improve the applicability of the three-lumen two-balloon tube body 7. The remaining features are the same as in Example 1.

[0025] The working principle is as follows: When the three-lumen two-balloon tube body 7 needs to be used, the esophageal balloon 12 and gastric balloon 13 on the three-lumen two-balloon tube body 7 are first reduced in diameter by mechanical compression. The balloon-reducing tube 4 is then removed, and one end of the tube groove 6 is opened. The balloon-reducing tube 4 is used to cover the reduced-diameter esophageal balloon 12 and gastric balloon 13 to prevent them from dispersing. Paraffin oil is evenly coated on the surfaces of the external catheter 1, the balloon-reducing tube 4, and the three-lumen two-balloon tube body 7 to ensure lubrication during insertion. After the balloon-reducing tube 4 is installed, one end of the external catheter 1 is inserted from the bottom of the three-lumen two-balloon tube body 7. The flexible guide wire 3 is passed through the threaded groove 5 inside the balloon-reducing tube 4 and rotated to keep the balloon-reducing tube 4 in the appropriate position. When installing the three-lumen two-balloon tube body 7, the arc-shaped guide tube 14 is first removed, and one end of the arc-shaped guide tube 14 is placed on the patient. Inside the nasal cavity, the connector 15 is used to block and prevent the arc-shaped guide tube 14 from slipping. The external catheter 1 is inserted through the opening of the arc-shaped guide tube 14. The esophageal balloon 12 and gastric balloon 13 inside the three-lumen two-balloon tube body 7 are narrowed, which reduces friction with the patient's esophagus when the external catheter 1 is inserted, thereby improving the patient's comfort. After insertion, the flexible guide wire 3 is rotated to drive the rotating ring 2 to rotate. Through the threads in the threaded groove 5, the shrinking balloon tube 4 can slide to a certain extent. Then, the external catheter 1 is pulled out to drive the shrinking balloon tube 4, completing the placement of the three-lumen two-balloon tube body 7. The three-lumen two-balloon tube body 7 is inflated through the esophageal balloon tube 8 and gastric balloon tube 9. Medical staff can observe the reading on the pressure gauge 10 to judge the pressure of the balloon, prevent mucosal damage, and improve the applicability of the three-lumen two-balloon tube body 7.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
