Description

Technical Field

[0001] This utility model relates to the field of gastric tube technology, specifically to a modified three-lumen double-balloon gastric tube. Background Technology

[0002] Upper gastrointestinal bleeding is a common medical emergency. It is usually caused by massive bleeding due to rupture of esophageal varices or gastric varices. Currently, the main treatment is to use a triple-lumen double-balloon gastric tube with esophageal and gastric balloons to compress and stop the bleeding in the lower esophagus and gastric fundus. The gastric tube with esophageal and gastric balloons is usually inserted into the upper gastrointestinal tract through the patient's nasal cavity.

[0003] Utility model patent CN221751546U discloses a double-balloon reinforced gastric tube, including a main catheter. The main catheter has an inner lumen containing a first cavity, a second cavity, and a third cavity, with the first and second cavities located on either side of the third cavity. A first gas conduit and a second gas conduit are respectively disposed on both sides of one end of the main catheter, and are respectively conductively connected to one end of the first and second cavities. A first balloon and a second balloon are disposed on the outer wall of the other end of the main catheter. A stainless steel spring is embedded in the wall of the main catheter.

[0004] The above technical solution uses a main catheter to set up a first, second, and third cavity, and uses stainless steel springs to provide skeletal support for the main catheter, ensuring that the main catheter is resistant to bending and not easily kinked, resists thermal expansion and pressure from changes in patient posture during indwelling, maintains patency of the lumen, and solves the problem of product positioning accuracy, avoiding errors in balloon placement and ensuring accurate placement. However, the balloon and catheter of the three-lumen double-balloon gastric tube are prone to detachment from each other due to prolonged pressure hemostasis, affecting the precise use of pressure hemostasis. The balloon and catheter cannot be integrally molded, and the hemostatic clip at the end is not convenient for horizontal placement, making manual operation inconvenient. Furthermore, the three channels are not convenient for stable and independent ventilation. Utility Model Content

[0005] The purpose of this invention is to provide an improved three-lumen double-balloon gastric tube to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved three-lumen double-balloon gastric tube includes a main tube with a first cavity in the middle. Symmetrical ventilation holes communicating with the first cavity are located near the bottom of the outer wall of the main tube. A first conduit is located on the left side of the outer wall of the main tube, with a second cavity at the top and a first inflation port at the end of the second cavity. A first balloon is located on the outer wall of the main tube at the middle position corresponding to the first inflation port. A second conduit is located on the right side of the outer wall of the main tube, with a third cavity at the top and a second inflation port at the end of the third cavity. A second balloon is located on the outer wall of the main tube at the bottom position corresponding to the second inflation port.

[0008] Furthermore, clamping blocks are provided at the ends of the first and second pipes, and slots are provided in the middle of the clamping blocks corresponding to the first and second pipes, and notches are provided on one side wall of the clamping blocks to connect with the slots.

[0009] In this invention, the clamping block helps to hold the ends of the first and second pipes to prevent backflow of internal air. With the cooperation of the notch, the clamping block can be quickly installed at the ends of the first and second pipes, and its location at the ends facilitates quick and easy disconnection of the first and second pipes.

[0010] Specifically, the inner diameter of the slot is adapted to the outer diameter of the first pipe and the second pipe, and the width of the inner wall of the notch is smaller than the inner diameter of the slot.

[0011] In this invention, the notch width is smaller than the inner diameter of the slot, which helps to achieve flow-stopping fit after snapping and prevents it from falling off and affecting the flow-stopping operation. The slot snaps onto the first pipe and the second pipe, which helps to facilitate the filling of air into the second cavity and the third cavity.

[0012] It should be noted that the top of the main tube is provided with a guide tube, the first cavity passes through the guide tube, and a first limiting ring is provided at the top of the outer wall of the guide tube.

[0013] In this invention, the guide tube facilitates ventilation or infusion into the first cavity, and the first limiting ring facilitates hand-held operation, increases the point of leverage, and helps adjust the position of the guide tube end, making manual operation convenient.

[0014] Furthermore, both the first pipe and the second pipe are integrally formed with the main pipe. The first pipe has a second limiting ring at the top of its outer wall, and the second pipe has a third limiting ring at the top of its outer wall.

[0015] In this invention, the cooperation of the second and third limiting rings increases the contact area, thereby enabling the first and second pipes to be held in hand, facilitating the clamping of the blocks to stop flow or the removal of the blocks for inflation and delivery, and increasing the stability of the handheld mechanism.

[0016] Specifically, the first balloon and the main tube are integrally formed, the hollow area between the inner wall and the outer wall of the first balloon is the first inflation chamber, and the first inflation chamber is internally connected to the first inflation port.

[0017] In this invention, the first balloon and the main tube are integrally formed to avoid long-term pressure use, which could cause it to fall off and affect the corresponding position for hemostasis. With the cooperation of the first inflation port and the first inflation chamber, the inflation and deflation of the first balloon can be coordinated. Inflation is used for pressure hemostasis, and deflation is used for removal.

[0018] It is worth noting that the second balloon and the main tube are integrally formed, and the hollow area between the inner and outer walls of the second balloon is the second inflation chamber, which is internally connected to the second inflation port.

[0019] In this invention, the second balloon and the main tube are integrally formed and cooperate with the first balloon to achieve double balloon compression hemostasis. With the second inflation chamber and the second inflation port in place, it is convenient to coordinate inflation and deflation. Inflation is used for compression hemostasis, and deflation is used for removal and replacement.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model increases the overall structural stability by setting the first balloon, the second balloon and the main tube as an integrally formed structure. With the cooperation of the first tube and the second tube, the second cavity is connected to the first balloon, the third cavity is connected to the second balloon, and the first cavity penetrates the main tube, achieving the effect of three cavities and two balloons. The first tube and the second tube are clamped and fixed by the clamping block to prevent internal air backflow, which would affect the compression hemostasis. The overall structure is stable and the service life is extended.

[0022] 2. This utility model, by setting a guide tube with a first limiting ring, allows the first cavity to pass through the guide tube. With the cooperation of the first limiting ring, it is convenient to hand-hold and transport liquid or oxygen. With the cooperation of the second and third limiting rings, the hand-holding area is increased, which helps to hand-hold and cooperate with the first and second pipes. Attached Figure Description

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0035] Please see Figures 1-4 This embodiment provides a technical solution:

[0036] An improved three-lumen double-balloon gastric tube includes a main tube 1, a first cavity 12 in the middle of the main tube 1, a guide tube 11 at the top of the main tube 1, the first cavity 12 passing through the guide tube 11, and a first limiting ring 110 at the top of the outer wall of the guide tube 11.

[0037] In this invention, the guide tube 11 facilitates ventilation or infusion into the first cavity 12, and the first limiting ring 110 facilitates hand-held operation, increases the point of force, and helps adjust the position of the end of the guide tube 11, making manual operation convenient.

[0038] It should be noted that the outer wall of the main pipe 1 has symmetrical ventilation holes 10 near the bottom that communicate with the first cavity 12. The left side of the outer wall of the main pipe 1 has a first pipe 4. The top of the first pipe 4 has a second cavity 40. The end of the second cavity 40 has a first inflation port 41. The outer wall of the main pipe 1 has a first balloon 2 located in the middle corresponding to the first inflation port 41. The first balloon 2 and the main pipe 1 are integrally formed. The hollow area between the inner wall and the outer wall of the first balloon 2 is the first inflation chamber 20. The first inflation chamber 20 and the first inflation port 41 are internally connected.

[0039] In this invention, the first balloon 2 and the main tube 1 are integrally formed to avoid long-term pressure use and falling off, which would affect the corresponding position for pressure hemostasis. With the cooperation of the first inflation port 41 and the first inflation chamber 20, the first balloon 2 can be inflated and deflated in coordination. Inflation is used for pressure hemostasis, and deflation is used for removal.

[0040] Furthermore, a second pipe 5 is provided on the right side of the outer wall of the main pipe 1. A clamping block 6 is provided at the end of both the first pipe 4 and the second pipe 5. A slot 60 is provided in the middle of the clamping block 6 corresponding to the first pipe 4 and the second pipe 5. A notch 600 communicating with the slot 60 is provided on one side wall of the clamping block 6.

[0041] In this invention, the clamping block 6 helps to clamp the ends of the first pipe 4 and the second pipe 5 to prevent internal air backflow from affecting them. With the cooperation of the notch 600, the clamping block 6 can be quickly installed at the ends of the first pipe 4 and the second pipe 5. Being located at the ends facilitates quick and easy disconnection of the first pipe 4 and the second pipe 5.

[0042] Specifically, the inner diameter of the slot 60 is adapted to the outer diameter of the first pipe 4 and the second pipe 5, and the inner wall width of the notch 600 is smaller than the inner diameter of the slot 60.

[0043] In this invention, the width of the notch 600 is smaller than the inner diameter of the slot 60, which helps to achieve flow-stopping fit after snapping and prevents it from falling off and affecting the flow-stopping operation. The slot 60 snaps onto the first pipe 4 and the second pipe 5, which helps to facilitate the filling of air into the interior through the second cavity 40 and the third cavity 50.

[0044] It is worth noting that the first pipe 4 and the second pipe 5 are both integrally formed with the main pipe 1. The top of the outer wall of the first pipe 4 is provided with a second limiting ring 42, and the top of the outer wall of the second pipe 5 is provided with a third limiting ring 52.

[0045] In this invention, the second limiting ring 42 and the third limiting ring 52 work together to increase the contact area, thereby enabling the first pipe 4 and the second pipe 5 to be held in hand, facilitating the clamping block 6 to stop the flow or to remove the clamping block 6 for inflation and delivery, and increasing the stability of the handheld mechanism.

[0046] Furthermore, a third cavity 50 is provided at the top of the second pipe 5, and a second air inlet 51 is provided at the end of the third cavity 50. A second balloon 3 is provided on the outer wall of the main pipe 1 at the bottom position corresponding to the second air inlet 51.

[0047] Secondly, the second balloon 3 and the main tube 1 are integrally formed. The hollow area between the inner wall and the outer wall of the second balloon 3 is the second inflation chamber 30. The second inflation chamber 30 and the second inflation port 51 are internally connected.

[0048] In this invention, the second balloon 3 is integrally formed with the main tube 1 and cooperates with the first balloon 2 to achieve double balloon compression hemostasis. With the second inflation chamber 30 and the second inflation port 51 in cooperation, it is convenient to coordinate inflation and deflation. Inflation is used for compression hemostasis, and deflation is used for removal and replacement.

[0049] In this embodiment of the modified three-lumen double-balloon gastric tube, the guide tube 11 with the first limiting ring 110 is first connected to the main tube 1 with the first cavity 12. Then, the first tube 4 with the second cavity 40 is combined and fixed with the main tube 1, the second tube 5 with the third cavity 50 is combined and fixed with the main tube 1, and the first inflation port 41 is connected to the first inflation chamber 20 inside the first balloon 2 on the main tube 1, and the second inflation port 51 is connected to the second inflation chamber 30 inside the second balloon 3 on the main tube 1.

[0050] When inserted into the patient's stomach, the end of the main tube 1 is long and rounded, and lubricant is applied to the outer wall of the main tube 1 to facilitate the extension of the main tube 1 with the first balloon 2 and the second balloon 3 into the stomach. The first balloon 2 and the second balloon 3 are inflated sequentially through the first tube 4 and the second tube 5, and are engaged with the corresponding first tube 4 and second tube 5 through the notch 600 on the clamp block 6 to achieve tube flow cessation. This provides compression hemostasis to the lower esophagus and the fundus of the stomach. With the cooperation of the vent 10 on the main tube 1 and the first cavity 12, the corresponding gastric juice or medicine is delivered. The overall assembly structure is stable, and with the cooperation of the first limiting ring 110, the second limiting ring 42, and the third limiting ring 52, it is easy to hold and operate.
