[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figure 1-Figure 4 As shown, an anti-reflux stomach tube includes a stomach tube body 1 and a nasogastric tube 6. A connecting tube 2 is fixedly installed at one end of the stomach tube body 1. A connecting tube 3 is fixedly installed on the surface of the connecting tube 2. The stomach tube body 1 and the connecting tube 3 are both perpendicular to the surface of the connecting tube 2. A sealing component 4 is fixedly installed at the opening of the connecting tube 2. The sealing component 4 is used to seal the top opening of the stomach tube body 1. The nasogastric tube 6 penetrates and is inserted into the connecting tube 3 and the connecting tube 2. The nasogastric tube 6 is used to release the sealing of the stomach tube body 1 by the sealing component 4. Before the nasogastric tube 6 is inserted into the connecting tube 3, the outer wall of the nasogastric tube 6 and the inner wall of the connecting tube 3 can be wiped with alcohol cotton for disinfection. A spacer component 5 is fixedly installed at the top of the stomach tube body 1, and the spacer component 5 is attached to the front and back sides of the connecting tube 2.

[0020] When in use, the sealing assembly 4 includes a connecting tube 2 41 fixedly mounted at the opening of the connecting tube 1 2, a spring 42 fixedly mounted on the inner wall of the left side of the connecting tube 2 41, a blocking piece 43 fixedly mounted on the other end of the spring 42, the outer diameter of the connecting tube 2 41 is equal to the outer diameter of the connecting tube 1 2, the inner diameter of the connecting tube 2 41 is greater than the inner diameter of the connecting tube 1 2, and the diameter of the blocking piece 43 is equal to the inner diameter of the connecting tube 2 41. The blocking piece 43 fits on the left end of the connecting tube 1 2, and the blocking piece 43 has a tendency to move to the right due to the elasticity of the spring 42. When the blocking piece 43 fits on the left end of the connecting tube 1 2, the left end of the connecting tube 1 2 is sealed. A plug post 44 is fixedly mounted on the right side of the blocking piece 43, and an inclined portion 45 is provided on the top of the plug post 44. The plug post 44 is inserted into the connecting tube 1 2, and the plug post 44 fits on the top of the gastric tube body 1. Thus, the top of the gastric tube body 1 is sealed by the plug post 44, thereby ensuring that the gastric tube body 1 is in a sealed state. During the process of inserting the nasogastric tube 6 into the connecting tube 3, the connecting tube 1 2 and the stomach tube body 1, the nasogastric tube 6 is pressed against the inclined portion 45 of the plug post 44, thereby pushing the plug post 44 to move into the connecting tube 2 41, so that the plug post 44 is removed from the opening of the stomach tube body 1, thereby releasing the sealing effect on the stomach tube body 1. The elasticity of the spring 42 makes the plug post 44 closely attached to the surface of the nasogastric tube 6, thereby preventing the nasogastric tube 6 from being separated from the connecting tube 3, the connecting tube 1 2 and the stomach tube body 1.

[0021] The blocking piece 43 is provided with an array of embedded blocks 46 on the circumferential surface, and the inner wall of the connecting tube 2 41 is provided with an array of guide grooves 47, and the embedded blocks 46 correspond to the guide grooves 47 one by one, and the embedded blocks 46 are slidably connected in the guide grooves 47. Thus, the moving path of the blocking piece 43 and the plug post 44 is guided by the cooperation of the guide grooves 47 and the embedded blocks 46, and the deflection of the blocking piece 43 and the plug post 44 during the movement is prevented, and the inclined portion 45 of the plug post 44 is prevented from deflecting toward the top opening of the gastric tube body 1, so that the lower half of the plug post 44 can be stably attached to the opening of the gastric tube body 1, and the gastric tube body 1 is stably sealed. The right inner wall of the connecting tube 1 2 is provided with an embedded groove 21, and the top wall of the embedded groove 21 is adapted to the inclined portion 45, and the right end of the plug post 44 is embedded in the embedded groove 21. A magnetic block 1 48 is embedded inside the right end of the plug post 44, and a magnetic block 2 49 is embedded inside the right end of the connecting tube 1 2. The magnetic blocks 1 48 and 2 49 have opposite polarities at one end. The attraction between the magnetic blocks 1 48 and 2 49 increases the driving force for inserting the plug post 44 into the slot 21, preventing the end of the plug post 44 from rubbing against the inner wall of the slot 21 too much and making it difficult to insert.

[0022] Specifically, the spacing component 5 includes a fixing ring 51 fixedly mounted on the top of the gastric tube body 1, and two arc-shaped gaskets 52 distributed front and back are integrally formed on the top of the fixing ring 51, and the fixing ring 51 and the arc-shaped gasket 52 are both made of silicone. The two arc-shaped gaskets 52 are respectively attached to the front and back sides of the connecting tube 2. In daily use, the top of the gastric tube body 1 is fixed on the skin by adhesive tape, and the connecting tube 2 is separated from the patient's skin by the arc-shaped gasket 52 to prevent the hard connecting tube 2 from being squeezed on the skin and causing discomfort to the patient.

[0023] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
