[0002] A gastric tube is a tube used for gastrointestinal treatment. It can inject nutrient solution, food, etc. directly into the stomach to provide nutrition for patients who cannot eat orally (such as patients in a coma, dysphagia, patients after oral surgery, etc.). Gastric lavage fluid can also be injected into the stomach through the gastric tube and then sucked out to remove toxins or irritants in the stomach, such as food poisoning. The gastric tube can also effectively drain gas and fluid accumulation in the gastrointestinal tract, reduce gastrointestinal pressure, and relieve abdominal distension. It is often used in intestinal obstruction, acute gastric dilatation, and post-operative gastrointestinal perforation repair.

[0003] At present, the various gastric tubes used in clinical practice are simply classified by tube length or number of inner cavity holes to treat various single gastrointestinal cases respectively. They are not convenient for adjustment or combination use, and it is difficult to meet the needs of different treatment methods.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Please see the attached Figure 1-8 In one embodiment of the present invention, an adjustable combined multi-lumen gastric tube includes a catheter 2, with diversion holes 3 formed on both sides of the catheter 2, and guide plates 4 connected to opposite sides of the catheter 2. When the catheter 2 is connected to the single connector 1, it can be used as a single-lumen catheter alone.

[0034] When the catheter 1 2 is used in combination, the catheter 1 2 is connected to the catheter 2 7 inside. The catheter 2 7 has positioning grooves 11 on both sides. The positioning grooves 11 cooperate with the guide plate 4. At this time, the catheter 1 2 is connected to the multi-connector 6 and can be used as a three-lumen catheter.

[0035] A telescopic tube 5 is connected to one side of the catheter 1 2 to facilitate adjustment of the length of the gastric tube. The telescopic tube 5 includes an outer tube 51 and an inner tube 52. The inner tube 52 is slidably connected to the inside of the outer tube 51. The outer tube 51 and the inner tube 52 are mutually limited. A catheter 3 9 is fixedly connected to the middle of the inner tube 52. The catheter 3 9 is slidably connected to the inside of the catheter 2 7.

[0036] The first limit blocks 53 are fixedly connected to both sides of the inner tube 52, and the second limit blocks 56 are connected to both sides of the outer tube 51. The first limit blocks 53 and the second limit blocks 56 cooperate with each other. When the first limit blocks 53 and the second limit blocks 56 are connected, the inner tube 52 and the outer tube 51 can be limited and fixed.

[0037] One end of the outer tube 51 is fixedly connected to the catheter 2. A cavity 54 is opened inside the outer tube 51. The inner tube 52 and the cavity 54 are mutually connected. The inner tube 52 is connected to the inside of the outer tube 51 through the cavity 54.

[0038] A limiting groove 55 is provided on one side of each guide plate 4, and the limiting groove 55 is communicated with the cavity 54. Two second limiting blocks 56 are fixedly connected to the inside of the two limiting grooves 55 respectively. The first limiting block 53 and the second limiting block 56 are both composed of a plurality of continuous triangular blocks, and the first limiting block 53 and the second limiting block 56 are engaged with each other. When the gastric tube is too long, the inner tube 52 can be inserted into the outer tube 51 to shorten the length, thereby avoiding the phenomenon of tube removal due to excessive length of the gastric tube.

[0039] One side of the guide plate 4 and the positioning groove 11 are both arranged in a long arc shape, and guide grooves 10 are provided on both sides of the conduit three 9. The guide grooves 10 are fitted with and connected to the positioning grooves 11. When connected, the guide plate 4 can guide and limit the conduit three 9 through the guide grooves 10 to prevent it from self-rotating during use. At the same time, the guide grooves 10 are connected to the positioning grooves 11, which can guide and limit the conduit two 7, thereby enhancing the stability of its connection and the reliability of its use.

[0040] Two relatively arranged connecting plates 8 are fixedly connected between the inner tube 52 and the conduit three 9. The connecting plates 8 are arranged in a flat shape. The connecting plates 8 can fix the inner tube 52 and the conduit three 9. At the same time, when in use, the diversion fluid can slide down along the connecting plates 8.

[0041] The connector of catheter 1 2 can be a single connector 1 or a multiple connector 6. When catheter 1 2 is used alone, it is connected to the single connector 1. When catheter 1 2 is used in combination, it is connected to the multiple connector 6. At this time, the interior of catheter 1 2 is divided into three chambers. The two ends of the guide plate 4 are located on the outside of catheter 2 7, and are respectively provided with a second chamber 13 and a first chamber 12. A third chamber 14 is provided on the inside of catheter 2 7, which is convenient for use with different treatment methods.

[0042] Both sides of the second conduit 7 and the third conduit 9 are provided with diversion side openings 15 to facilitate diversion of the liquid.

[0043] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
