According to the data of the annual report of registration of cancer in China in 2014, digestive tract tumors such as gastric cancer, liver cancer, esophageal cancer and colorectal cancer cause huge burden on the health of people in China. At present, 80% of esophageal cancer and gastric cancer are detected in China as the progressive stage, and surgical operation treatment, proximal and distal major gastrectomy, esophagogastrostomy or esophagogastrostomy after esophago-esophageal tumor resection are needed. After surgical resection, anastomotic fistula is a common complication, once the anastomotic fistula occurs, treatment is complex and difficult, the disease condition can not be cured for a long time, heavy economic burden is brought to patients, meanwhile, great mental burden is brought to doctors and patients, and even the patients die because the fistula is not cured.

The current common prevention mode is that a negative pressure drainage tube is placed around the anastomotic fistula after operation to suck out digestive juice in the upper digestive tract, so that the anastomotic fistula is prevented or the digestive juice is furthest reduced from leaking outside after the anastomotic fistula occurs, and the healing of the fistula is promoted. Meanwhile, the postoperative patient is advocated to recover quickly at present, the active enteral nutrition can promote the patient to heal quickly, and the intestinal nutrition is usually carried out by a jejunum nutrient canal in the initial postoperative stage. In addition, at present, patients with acute pancreatitis and severe pancreatitis often need negative pressure drainage of gastric juice and jejunal nutrition at the same time.

Detailed Description

The present invention will be described in further detail with reference to the drawings and examples, but the scope of the present invention is not limited thereto.

As shown in fig. 1, 2 and 6, the present invention provides a negative pressure suction jejunal nutrition tube 100, which comprises a stomach suction cavity 1, an intestine feeding cavity 2 and a pressure adjusting cavity 3. The outer walls of the gastric suction lumen 1, the enteral feeding lumen 2 and the pressure regulating lumen 3 are bonded to each other in parallel to form a three-lumen structure. The top ends of the gastric suction lumen 1, the enteral feeding lumen 2 and the pressure regulating lumen 3 may be separated by a certain distance as required. The stomach suction cavity 1 is communicated with a stomach or esophagus anastomosis opening, the top end of the stomach suction cavity 1 is provided with a negative pressure drainage opening 11, and the bottom end of the stomach suction cavity 1 is provided with a plurality of side openings 12, so that the negative pressure drainage function is realized. The negative pressure suction jejunum nutrient canal 100 is inserted into a nasal cavity of a human body, a plurality of side holes 12 are arranged at the bottom end of the stomach suction cavity 1, wherein the distance between one side hole 12 located at the uppermost part and the nasal cavity is 20-50 cm, and preferably 30-40 cm.

The cavity 2 is fed to jejunum, the top of the cavity 2 is provided with a nutrition filling opening 21, the bottom of the cavity 2 is also provided with a plurality of side openings 22, when the nutrition tube 100 capable of sucking jejunum by negative pressure is inserted, the bottom of the cavity 2 can reach the duodenum opening, thus realizing the jejunum nutrition function. The gastric aspiration lumen 1 and the enteral feeding lumen 2 are provided with a plurality of side holes in order to avoid the gastrointestinal mucosa from blocking the orifice. Lids (13, 23) are provided on both the negative pressure drainage port 11 and the nutrition injection port 21 to close the respective inlets, and are opened when needed, thereby preventing the stomach suction chamber 1 and the intestine feeding chamber 2 from being contaminated as much as possible. In addition, a water bag 24 is provided on the outer wall of the lower end of the cavity 2 for enteral feeding, and the water bag 24 is communicated with the pressure-adjusting cavity 3, so that the physiological saline or distilled water can be injected through a liquid injection port 31 provided at the upper end of the pressure-adjusting cavity 3, and the injected physiological saline or distilled water can reach the water bag 24. Because the vacuum suction jejunal nutrient canal 100 is placed in the body under the guidance of the endoscope, and the normal saline or distilled water is injected into the water bag 24, the water bag 24 bears a certain weight, when the endoscope is taken out, the vacuum suction jejunal nutrient canal 100 can not be taken out by the endoscope, and after the endoscope is taken out, the vacuum suction jejunal nutrient canal 100 can continuously move to the jejunum along with the peristalsis of the intestinal tract under the guidance of the gravity of the water bag 24. The stomach suction cavity 1, the intestine feeding cavity 2 and the pressure adjusting cavity 3 can be made of medical plastic materials such as polyurethane and the like. The diameters of the stomach suction cavity 1, the intestine feeding cavity 2 and the pressure adjusting cavity 3 are 2-7 mm, preferably 5-5.5 mm.

As can be seen from figures 2, 3, 4, 5 and 6, the gastric suction lumen 1 is closed at the C-C position where it can suck the jejunal feeding tube 100 under negative pressure and also at the lower end of the gastric suction lumen 1, which reduces adherence and prevents the gastric mucosa from blocking the orifice.

As shown in figure 7, in order to facilitate the operation of placing the tube, a threading hole 4 is arranged at the lowest end of the vacuum suction jejunum nutrient canal 100 along the diameter of the vacuum suction jejunum nutrient canal 100, the threading hole 4 is communicated with the intestine feeding cavity 2, thus when the tube is placed, a thread can be threaded through the threading hole 4, the thread is knotted into a small coil, when the tube is placed, the coil is clamped by a biopsy forceps and is sent to the jejunum along with an endoscope. In addition, the threading hole 4 passes through the pipe walls (101, 102) of the vacuum suction jejunal nutrient pipe 100, so that the thread can be threaded into the threading hole 4 from the outside of the pipe walls (101, 102) of the vacuum suction jejunal nutrient pipe 100.

Aiming at the upper gastrointestinal esophagectomy and the postoperative design of the major part of the stomach, the vacuum suction jejunum nutrient canal 100 can realize the vacuum drainage and jejunum nutrition around the anastomotic stoma, the water sac 24 is arranged to facilitate the bottom end of the vacuum suction jejunum nutrient canal 100 to reach the jejunum, and the lowest end of the vacuum suction jejunum nutrient canal 100 is provided with a threading hole to facilitate the canal placement.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
