Problems solved by technology

[0002] The current gastric tubes only have single-lumen or double-lumen gastric tubes. Single-lumen gastric tubes have many disadvantages, such as gastrointestinal decompression and nutrition cannot be carried out at the same time, and gastric mucosa is easily damaged during drainage, causing gastric bleeding, gastric tube blockage, etc.
Although the double-lumen gastric tube has many advanced features, the existing double-lumen gastric tube also has disadvantages, such as gastric decompression, anti-slip, and simultaneous use of jejunum or duodenal nutrition, etc. At this time, the disadvantages of the double-lumen gastric tube appear. Moreover, the existing double-lumen gastric tubes only combine the functions of two single-lumen gastric tubes into one, and they have interconnected common cavity holes. When used in patients, they directly form the passage between the patient's stomach and the outside world, and simultaneously Although the two treatment methods play the role of 1+1=2; but when two treatments are carried out at the same time or a foreign body blocks the outlet of one cavity of the gastric tube, it will affect the other cavity, so it can only be taken out and cleaned or reinstalled. Change
This will not only increase the pain of the patient, but also prolong the treatment time of the disease; when the patient needs to treat the stomach and duodenum or jejunum at the same time, there is nothing they can do

Embodiment 1

[0032] Example 1, scheme 1, three-cavity gastric tube without bag, refer to figure 1 .

[0033] The present invention includes a main body 2, which is divided into three tubular lumens extending along the length direction of the tubular body; the first tubular lumen is a decompression discharge lumen 3, and the second tubular lumen is used as Regulating lumen 4, wherein the third tubular lumen is used as nutrient delivery lumen 7; at the inlet end of the main body, the above-mentioned three tubular lumens 3, 4, 7 have openings respectively; the decompression and discharge lumen 3 There are a plurality of first holes 5 leading to the outside of the main tube in the head area, and a plurality of second holes 8 leading to the outside of the main tube are provided in the head area of ​​the nutrient delivery lumen 7. The head of the regulating lumen 4 The upper area is provided with a plurality of third holes 6, and the third holes lead to the outside of the main pipe.

Embodiment 2

[0037] Example 2, scheme 2, the three-lumen gastric tube without a capsule, and the nutrient delivery lumen has an extended part, refer to figure 2 .

[0038] This embodiment builds on the basis of embodiment 1, in figure 2 In the appended figure and figure 1 The same means the same meaning.

[0039] In this embodiment, an extension 70 of the nutrient delivery lumen 7 is provided, and the extension 70 is connected to the head of the third tubular lumen as the nutrient delivery lumen 7, and the second hole 8 is arranged at the nutrient delivery lumen 7. The head region of the prolongation 70 of the lumen, which serves as a duodenal or jejunal nutrient delivery lumen.

[0040] In this embodiment, under the condition that the structure of the decompression and discharge lumen remains unchanged, the nutrient delivery lumen is appropriately extended as the nutrient delivery lumen of the duodenum or jejunum, and the stomach and duodenum or When the jejunum needs to be treated ...

Embodiment 3

[0041] Example 3, one of scheme 3, three-cavity gastric tube with bag, refer to Figure 3a , 3b .

[0042]The present invention includes a main body 2, which is divided into three tubular lumens extending along the length direction of the tubular body; the first tubular lumen is a decompression discharge lumen 3, and the second tubular lumen is used as Regulating lumen 4, wherein the third tubular lumen is used as the filling lumen 200; at the inlet end of the main body, the above-mentioned three tubular lumens 3, 4, 7 have openings respectively; the decompression and discharge lumen 3 The head area of ​​the regulating lumen 4 has a plurality of first holes 5 leading to the outside of the main tube, and the head area of ​​the regulating lumen 4 is provided with a plurality of third holes 6 .

[0043] The present invention is provided with the bag 300 that is wrapped in the periphery of main body 2 in the middle part of main body, and described bag is used for matching with g...

Abstract

The invention provides a three-cavity nasogastric tube, which comprises a main tube body, wherein the main tube body is partitioned into three tubular cavities extending along the length direction of the tube body; a first tubular cavity is a pressure-reducing drainage tube cavity; the second tubular cavity is taken as a nutrient conveying tube cavity or an adjusting tube cavity; and the third tubular cavity is taken as an adjusting tube cavity when the second tubular cavity is taken as a nutrient conveying tube cavity, and is taken as a nutrient conveying tube cavity when the second tubular cavity is taken as an adjusting tube cavity. Due to the adoption of the three-cavity nasogastric tube, smooth performance of nutrient conveying treatment can be ensured during stomach treatment. A patient can be treated in a plurality of treatment ways simultaneously, so that an optimal treatment effect is achieved at shortest treatment time with an optimal treatment scheme. The three-cavity nasogastric tube is further provided with a special fixed air bag, so that the nasogastric tube is prevented from being moved unconsciously by the patient during treatment, and safety and reliability are realized.
