[0023] The present invention provides a gastrointestinal decompression device:

[0024] like Figure 1-Figure 4 As shown, it includes a negative pressure bottle 1 and a tube body 2. The negative pressure bottle 1 can be opened, and an air pump 12 is installed on the negative pressure bottle 1. The tube body 2 is installed on one side of the upper part of the negative pressure bottle 1 and is connected with the inside thereof, and the extracted accumulated fluid can fall to the bottom of the bottle of the negative pressure bottle 1. Two air tubes 3 are arranged on the outside of the tube body 2, and the air tubes 3 are arranged in contact with the tube body 2. The air tubes 3 are fixed to the tube body 2, and an air pump 4 is fixed to the side of the negative pressure bottle 1. One end of the air tube 3 is connected to the air pump 4, and an extraction tube 5 is installed at the end of the tube body 2 away from the negative pressure bottle 1. Two airways 6 are provided in the extraction tube 5, and the other ends of the two airways 3 are respectively connected to the two airways 6. A plurality of protrusions 7 are installed on the other end of the extraction tube 5, and a diffusion strip 8 is hinged on the other side of the protrusion 7. A film 9 is installed between two adjacent diffusion strips 8, and the film 9 is made of non-toxic rubber film. The protrusion 7 and the diffusion strip 8 are connected by an elastic film 13, and the elastic film 13 is made of plastic material and occupies There are fewer positions and a long expansion life. The right end of the film 9 is looser than the left end, so it is easier to achieve a trumpet shape. The protrusion 7 is sealed with the diffusion strip 8. A dilator 10 is provided on the right side of the extraction tube 5. The dilator 10 is made of non-toxic rubber and can pass through the esophagus more smoothly. The diffusion strips 8 are all in the dilator 10 and fixed to the inner wall of the dilator 10. A plurality of mesh holes 14 are provided on the dilator 10. There are multiple wrinkles inside the foldable dilator 10. The diffusion strips 8 are respectively fixed to the wrinkles. Folding airbags 11 are installed on both ends of the dilator 10. The shape of the folding airbags 11 is the same as the folding shape of the dilator 10. The folding points of the two are fixed, which makes it easier to pull. The two airways 6 are respectively connected to the two folding airbags 11. After the folding airbags 11 are inflated, they can pull the dilator 10 to stretch. The dilator 10 can drive the diffusion strips 8 to expand outward, so that the multiple diffusion strips 8 cooperate with the film 9 to form a trumpet-shaped structure.

[0025] When in use, after the diffusion strip 8 and the dilator 10 are folded, they can be inserted into the patient's stomach together with the extraction tube 5. The folded state is easier to insert, and then the inflation pump 4 is controlled to inflate to expand the folded airbag 11. After the folded airbag 11 is inflated, it can pull the dilator 10 to stretch. The dilator 10 can drive the diffusion strip 8 to expand outward, so that multiple diffusion strips 8 cooperate with the film 9 to form a trumpet-shaped structure. At this time, the extraction tube 5 can extract gas or fluid from the stomach. When the dilator 10 contacts the stomach wall, the remaining mesh holes 14 can still be used for extraction. The negative pressure of the mesh holes 14 in the contact part is small, and the stomach wall will not be damaged. Moreover, the internal trumpet-shaped structure does not affect the pressure and can continuously extract without changing the position back and forth.
