Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a multi-purpose decompression feeding tube. Background Art

[0002] Gastric cancer, pancreatic cancer, gallbladder cancer, and duodenal cancer are common malignant tumors of the digestive tract, accounting for more than 50% of digestive tract tumors. Roux-Y anastomosis and Billroth II gastrointestinal anastomosis are commonly used surgical treatments. In order to reduce the probability of duodenal stump leakage, bile-enteric anastomotic leakage, or gastrointestinal anastomotic leakage, decompression operations are usually required at the input end of the anastomosis.

[0003] During the medical process, in order to reduce the pressure at the anastomosis, doctors often place a gastric tube at the input end of the anastomosis to perform a decompression operation, thereby draining out excess liquid or gas near the anastomosis to achieve the decompression effect. However, the disadvantage of this method is that it can only provide a decompression effect and cannot simultaneously deliver enteral nutrition to the output end of the anastomosis. In order to make up for the limitation that the gastric tube can only reduce pressure, an additional operation is required at the output end of the anastomosis - jejunal nutrition tube insertion. This will not only increase the time of anesthesia surgery, but also increase the risk of complications such as postoperative intestinal obstruction and intestinal leakage, and increase the patient's medical expenses.

[0004] Therefore, how to develop a multi-purpose decompression feeding tube with ingenious design and easy use, which can meet the needs of gastrointestinal decompression and intestinal nutrient delivery at the same time, and at the same time, the split-design drainage tube and jejunal tube can be adjusted at different angles according to actual clinical needs to meet the needs of use in more scenarios, has become a technical problem that needs to be solved urgently by people in this field.

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] like Figure 1-3 As shown, a multi-purpose decompression feeding tube includes a drainage tube 1, a pressure regulating tube 2, a suction tube 3, a jejunal tube 4 and a three-cavity connector 5. The three-cavity connector 5 is inserted into the outer end of the drainage tube 1 and serves to seal the outer end opening of the drainage tube 1. The pressure regulating tube 2 and the suction tube 3 are connected to the drainage tube 1 after passing through the three-cavity connector 5. The drainage tube 1 is respectively provided with a clamping groove 6 and a plurality of drainage holes 7 on both sides near the inner end opening. A first through hole 8 is provided on the side of the drainage tube 1 where the clamping groove 6 is provided, and the first through hole 8 is located above the clamping groove 6. One end of the jejunal tube 4 passes through the three-cavity connector 5 and enters the inner cavity of the drainage tube 1, and extends outward through the first through hole 8.

[0027] Specifically, the drainage tube 1 includes a first drainage tube 11 and a second drainage tube 12. The diameter of the second drainage tube 12 is smaller than the diameter of the first drainage tube 11. The three-chamber connector 5 is inserted into the top of the first drainage tube 11 and serves to seal the top opening of the first drainage tube 11. The second drainage tube 12 is eccentrically arranged at the bottom end of the first drainage tube 11 and is connected to the first drainage tube 11. The plurality of drainage holes 7 are evenly arranged on one side of the second drainage tube 12. The clamping groove 6 is arranged on the other side of the second drainage tube 12. The first through hole 8 is opened at the bottom end of the first drainage tube 11.

[0028] Specifically, the design of multiple drainage holes 7 can not only increase the drainage area and make the drainage more uniform and efficient, but also reduce the patient's discomfort. Distributed drainage is performed through multiple drainage holes 7, which reduces pressure and stimulation on surrounding tissues, thereby reducing the patient's discomfort; and it also avoids blockage and ensures smooth drainage.

[0029] Specifically, the clamping groove 6 for clamping the jejunal tube 4 is arranged in a C shape, and the size of the clamping groove 6 matches the size of the jejunal tube 4.

[0030] Specifically, the first through hole 8 and the clamping groove 6 are set, and the jejunal tube 4 extends outward through the first through hole 8 to achieve a split operation with the second drainage tube 12. The user can freely choose the clamping state of the jejunal tube 4 and the clamping groove 6 according to the actual clinical needs of the patient;

[0031] Specifically, such as Figure 4 As shown in the figure, the device is used in the case where obstruction occurs at the distal end of the stomach (usually the pyloric area) or the duodenum, and a non-surgical treatment method is selected. At this time, the jejunal tube 4 is completely engaged and connected in the engaging groove 6 and is in the same direction as the second drainage tube 12. When in use, the device can be delivered into the patient's body by pushing or through an endoscope with clamps, so that the second drainage tube 12 remains in the patient's stomach to perform gastric decompression; while the jejunal tube 4 is delivered through the distal end of the stomach to the jejunum behind the ligament of Treitz to perform enteral nutrition delivery.

[0032] Specifically, such as Figure 5 As shown in the figure, the application diagram of the present invention is when performing Billroth II gastrointestinal anastomosis surgery. At this time, the jejunal tube 4 and the second drainage tube 12 are facing different directions respectively, and the jejunal tube 4 and the clamping groove 6 are in a partially clamped or unclamped state. The user can adjust the clamping state of the jejunal tube 4 and the clamping groove 6 and the separation angle of the jejunal tube 4 and the second drainage tube 12 according to actual conditions to meet the actual clinical needs of the patient. When in use, the present invention can be delivered into the patient's body by pushing or through an endoscope with clamps. The second drainage tube 12 enters the jejunal part through the gastrointestinal anastomosis and extends upward to the duodenum to perform drainage decompression operation, thereby reducing the probability of bile refluxing into the stomach and causing bile reflux esophagitis; while the jejunal tube 4 enters the jejunal part through the gastrointestinal anastomosis and extends downward to a deeper position to perform jejunal nutrition delivery operation.

[0033] Specifically, the jejunal tube 4 includes a catheter 41 and a first connector 42. One end of the catheter 41 passes through the three-cavity connector 5 and enters the inner cavity of the first drainage tube 11, and extends outward through the first through hole 8. The first connector 42 is installed at the other end of the catheter 41 and is used to connect to the nutrient solution container or syringe.

[0034] Specifically, a plurality of second through holes 9 are formed in a circumferential shape on the side wall of the conduit 41 at one end away from the first connector 42 .

[0035] Specifically, the setting of the second through hole 9 can distribute the nutrient solution or medicine more evenly in the intestine, avoid excessive accumulation of nutrients in a certain area, thereby improving the absorption efficiency and therapeutic effect of nutrients. At the same time, the setting of the second through hole 9 can also reduce the flow resistance in the pipeline and reduce the risk of pipe blockage. Even if some through holes are blocked, other through holes can still continue to work to ensure the smooth delivery of the nutrient solution.

[0036] In addition, the multiple second through holes 9 opened in a circular shape can also help reduce irritation and damage to the intestinal mucosa. The nutrient solution or medicine enters the intestine slowly and evenly through the multiple small holes without causing excessive impact or pressure on the intestinal mucosa, which helps to reduce the patient's discomfort and improve the comfort of treatment.

[0037] Specifically, the pressure regulating tube 2 includes a pressure regulating tube body 21 and a cap 22. One end of the pressure regulating tube body 21 is connected to the three-chamber connector 5 and is connected to the first drainage tube 11. The other end of the pressure regulating tube body 21 is installed with the cap 22.

[0038] Specifically, the suction tube 3 includes a suction tube body 31 and a second connector 32. One end of the suction tube body 31 is connected to the three-chamber connector 5 and is connected to the first drainage tube 11. The second connector 32 is installed at the other end of the suction tube body 31 and is used to be connected to the gastrointestinal decompression device.

[0039] The operating principle of this utility model is as follows:

[0040] By changing the engagement state of the jejunal tube 4 and the engaging groove 6, the separation angle of the jejunal tube 4 and the second drainage tube 12 is adjusted. The user can make adjustments according to the actual clinical needs of the patient, so that the jejunal tube 4 and the second drainage tube 12 can face different directions respectively to meet the usage requirements in different situations.
