Description

Technical Field

[0001] The utility model relates to the technical field of an internal drainage type nasoenteric nutrition tube, in particular to an internal drainage type nasoenteric nutrition tube. Background Art

[0002] At present, the treatment for gastric emptying disorder after gastrointestinal surgery is a double-tube treatment method, that is, using a nasogastric tube for gastrointestinal decompression to drain gastric juice, and using a nasogastric tube for enteral nutrition therapy. The specific operation is to insert two nasogastric tubes into the same nasal cavity at the same time, inject nutrient solution into the intestine through one nasogastric tube, and extract gastric juice from the other nasogastric tube. If gastric juice needs to be reinfused, the gastrointestinal decompression liquid needs to be repeatedly collected and manually reinfused into the nasogastric tube connected to the intestine. Therefore, an internal drainage nasogastric nutrition tube is urgently needed to solve the problem that nursing is time-consuming and labor-intensive, and the placement of the gastric tube and nutrition tube through the nasal cavity is prone to cause obvious discomfort.

[0003] In order to overcome these disadvantages, the utility model provides an internal drainage type nasoenteral nutrition tube. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an internal drainage type nasoenteric nutrition tube.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an internal drainage type nasoenteric nutrition tube, including an injection tube, characterized in that a card slot is provided on the outer side of the injection tube near the bottom end, a drainage tube is sleeved in the card slot, a main liquid outlet is opened at the central position of the bottom end of the injection tube, and a plurality of side liquid outlets are opened at the bottom end of the injection tube located on the side of the main liquid outlet.

[0006] Furthermore, the drainage tube includes an inner tube wall and an outer tube wall connected end to end, and the outer side of the outer tube wall is a wavy structure.

[0007] Furthermore, a plurality of drainage openings penetrating the outer tube wall are provided at the valleys of the wave-shaped structure on the outer side of the outer tube wall.

[0008] Furthermore, the length of the injection tube is 145 cm, and the card slot is arranged at 90 cm away from the open end of the injection tube.

[0009] Furthermore, the injection tube and the drainage tube are both X-ray-opaque polyurethane tubes.

[0010] Beneficial effects of the utility model:

[0011] When the utility model is in use, the internal drainage nasoenteral nutrition tube is of combined design, and the injection tube and the drainage tube are connected with the card slot, which is convenient for disassembly and cleaning of the drainage tube, reduces the intubation time, and can realize dual use of one tube, thereby alleviating the pain of the patient. The injection tube is used for conveying nutrient solution into the intestine, and the gastric juice can flow into the intestine by gravity through the drainage port on the drainage tube, which can reduce the loss of gastric juice and is beneficial to the balance of water and electrolyte of the patient. The outer tube wall of the drainage tube is a wavy structure, and the drainage port is arranged at the valley of the wavy structure, which can avoid the drainage port being blocked by the inner wall of the intestine.

[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 of 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 1-3As shown, it relates to an internal drainage type nasoenteral nutrition tube, including an injection tube 1, a card slot 3 is arranged on the outer side of the injection tube 1 near the bottom end, a drainage tube 2 is sleeved in the card slot 3, and the combined design connects the injection tube 1 and the drainage tube 2 with the card slot 3, which is convenient for disassembly and cleaning of the drainage tube 2, a main liquid outlet 4 is opened at the central position of the bottom end of the injection tube 1, and a plurality of side liquid outlets 5 are opened at the bottom end of the injection tube 1 at the side of the main liquid outlet 4, by injecting nutrient solution into the injection tube 1, the nutrient solution is discharged into the intestine through the main liquid outlet 4 and the side liquid outlet 5.

[0020] like Figure 1-3 As shown, the drainage tube 2 includes an inner tube wall 6 and an outer tube wall 7 connected end to end. The outer tube wall 7 has a wavy structure on the outside. A plurality of drainage ports 8 penetrating the outer tube wall 7 are provided at the valleys of the wavy structure on the outside of the outer tube wall 7. The drainage ports 8 are arranged at the valleys of the wavy structure to prevent the drainage ports 8 from being blocked by the inner wall of the intestine.
