[0019] In order to enable those skilled in the art to better understand and implement the technical solution of the present invention, the present invention is further described below in conjunction with specific embodiments and drawings.

[0020] In the description of the present invention, it should be noted that the terms "head", "tail", "inside", "outside", "upper", "middle", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0021] The utility model provides a three-chamber enteral nutrition tube, such as Figure 1 As shown, it includes a nutrition tube 1, a guide wire 2 is arranged inside the nutrition tube 1, a nasointestinal tube end 3 is arranged at the tail end of the nutrition tube 1, a stomach tube end 4 and a double-cavity nose sub-end 5 are arranged on the tail end tube wall of the nutrition tube 1, and a plurality of binding wires 6 are arranged at intervals on the nutrition tube 1. Among them, the function of the nasointestinal tube end 3 is to inject liquid diet, medicine and water, etc., to effectively provide nutritional support; the function of the stomach tube end 4 is gastrointestinal decompression; the function of the double-cavity nose sub-end 5 is that when the patient needs oxygen inhalation and the nutrition tube is inserted, the oxygen inhalation tube end can be connected to the double-cavity nose sub-end 5 on the three-cavity enteral nutrition tube at this time, reducing the factors of multiple tubes in the patient; the guide wire 2 is inside the nutrition tube 1, and when the tube is inserted, the success rate of tube insertion is increased. When the nasointestinal tube is blocked, the guide wire 2 can be used to clear the tube. During the operation, after the three-chamber enteral nutrition tube is inserted into the jejunum, the biopsy forceps 7 are used to fix the nutrition tube 1 to prevent the nutrition tube 1 from falling out, and then the guide wire 2 is pulled out; if the patient can be given nutritional support, nutritional support such as fluid, medicine and water can be given at the nasogastric tube end 3 after the tube is placed; if the patient is fasting and there is a risk of gastric retention, aspiration, etc., gastrointestinal decompression is given at the gastric tube end 4 and a negative pressure drainage bottle is connected; after the enteral nutrition tube is placed, if the patient needs oxygen, the double-chamber nasal end 5 can be directly connected.

[0022] In order to facilitate the traction of the nutrition tube 1 and place the nutrition tube 1 in a suitable position, the head end of the binding wire 6 is 2 cm away from the nutrition tube 1. The biopsy forceps 7 are used to clamp the binding wire 6 set on the nutrition tube 1 and send it to the jejunal segment to prevent the three-chamber enteral nutrition tube from slipping out easily.

[0023] In order to place the nutrition tube 1 to an appropriate depth, the number of the binding wires 6 is at least 3, and all the binding wires 6 are detachably arranged on the nutrition tube 1 at intervals. The binding wires 6 can be detachably arranged on the nutrition tube 1 by knotting, and two adjacent binding wires are spaced a certain distance apart, which can be suitable for different tube placement depths.

[0024] In order to further improve the practical applicability of the three-chamber enteral nutrition tube, the binding wire 6 includes a binding wire 1 61 , a binding wire 2 62 and a binding wire 3 63 .

[0025] In order to achieve effective placement of the three-chamber enteral feeding tube, the binding wire 61 is set at the head end of the feeding tube 1. Under endoscopy, the binding wire 61 set at the head end of the feeding tube 1 is clamped with a biopsy forceps to deliver the feeding tube 1 to the distal end of the duodenum.

[0026] In order to further achieve effective placement of the three-chamber enteral nutrition tube, the binding wire 2 62 and the binding wire 3 63 are fixed to the tube body of the nutrition tube 1 by knotting. The binding wire 2 62 is 15 to 20 cm away from the binding wire 1 61, and the binding wire 3 63 is 30 to 35 cm away from the binding wire 1 61. Under endoscopy, the binding wire 2 62 at a distance of 15 to 20 cm from the head end of the nutrition tube 1 is clamped with a biopsy forceps, and it can be smoothly delivered to the horizontal section of the duodenum under endoscopy. If it is set within about 15 cm, , which is not conducive to deeper insertion depth of the tube. Under endoscopy, clamp the binding wire 363 30 to 35 cm away from the head end with the biopsy forceps and insert it toward the gastric antrum so that the insertion depth reaches the jejunal segment. At this time, the biopsy forceps clamp the binding wire 363 without loosening it, and slowly pull out the guide wire 2 in the three-lumen enteral nutrition tube 1. At this time, the binding wire 363 of the three-lumen enteral nutrition tube 1 plays a fixed supporting role, and the guide wire 2 can be pulled out smoothly. The nutrition tube 1 is not easy to slip off, so that the medicine and various nutrient solutions fed by nasogastric feeding are effectively injected into the intestine, and are not easy to reflux, aspirate, or retain.

[0027] In order to prevent the binding wire from breaking and improve practical applicability, the binding wire 1 61, the binding wire 2 62 and the binding wire 3 63 are non-absorbable surgical sutures. The use of non-absorbable surgical sutures is simple, not easy to slip, and has appropriate thickness. The material of this wire is relatively flexible and not easy to break when binding. It is suitable for biopsy forceps and has low cost.

[0028] In order to achieve the purpose of enteral nutrition treatment, the diameters of the binding wire 1 61 , the binding wire 2 62 and the binding wire 3 63 are 0.1 cm, which is effective for biopsy forceps to clamp.

[0029] When in use, the tip end of the three-chamber enteral nutrition tube of the utility model is inserted from one nostril in the same way as inserting a gastric tube, with slow and gentle movements. When the tube is inserted about 25 cm into the esophagus or gastric cavity, an electronic gastroscope is used to lubricate the surface of the tube body and enter the gastric cavity from the mouth through the throat and esophagus.

[0030] At the tip of the nutrition tube 1, a non-absorbable surgical suture is used to tie a tie line 61 to 2 cm, which is the first auxiliary line. Under the endoscope, the auxiliary tie line 61 of the tip of the nutrition tube 1 is clamped by the biopsy forceps 7 and sent to the distal end of the duodenum. If the tip of the nutrition tube without an auxiliary tie line is sent to the distal end of the duodenum in the same way, the tip of the tube is easy to rebound and be pulled out, and the operation time is long. However, when the auxiliary tie line 61 of the tip is clamped by the tie line auxiliary method, when the endoscope is withdrawn to the gastric cavity, the tip of the tube is not easy to be pulled out and rebound, which plays a good traction role.

[0031] At 20 cm from the head end of the three-chamber enteral nutrition tube 1, a non-absorbable surgical suture is used to tie a knot to a 2 cm long line, which is the second auxiliary line, i.e., the second line 62. Under endoscopy, the auxiliary line 20 cm from the head end, i.e., the second line 62, is clamped by the biopsy forceps 7, and it can be smoothly delivered to the horizontal section of the duodenum under endoscopy. If there is no auxiliary line 20 cm from the head end, the tube is easy to be tangled during the placement process, which is not conducive to the deeper placement depth of the tube. Therefore, the second auxiliary line of the three-chamber enteral nutrition tube, i.e., the second line 62, can ensure a better placement effect and a deeper placement depth, thereby achieving the purpose of effective nutritional treatment.

[0032] At another place 35 cm away from the head end of the three-chamber enteral nutrition tube, use non-absorbable surgical suture to tie a knot to 2 cm. This is the third auxiliary line, i.e., binding line three 63. Under endoscopy, use biopsy forceps 7 to clamp the auxiliary binding line 35 cm away from the head end, i.e., binding line three 63, and send it toward the gastric antrum so that the catheter insertion depth reaches the jejunal segment. At this time, the biopsy forceps clamp the auxiliary binding line without loosening it, and slowly pull out the guide wire 2 in the three-chamber enteral nutrition tube 1. At this time, binding line three 63 plays a fixed support, the guide wire 2 can be pulled out smoothly, and the nutrition tube 1 is not easy to slip off, so that the medicine and various nutrient solutions fed by nasogastric feeding are effectively injected into the intestine, and are not easy to reflux, aspirate, or retain.

[0033] After checking under endoscopy that the three-chamber enteral nutrition tube 1 is not curled or coiled in the stomach cavity, the biopsy forceps are pulled out, and the gastroscope is withdrawn after the liquid and gas in the stomach cavity are completely aspirated. The three-chamber enteral nutrition tube 1 is properly fixed with elastic tape, and the insertion depth of the tube is recorded.

[0034] Clinical application examples

[0035] Example 1

[0036] The patient was admitted to the hospital because of abdominal distension and abdominal pain for 22 hours more than one year after liver transplantation. He was unable to receive nutritional support through self-diet, so he chose to insert a three-chamber enteral nutrition tube under endoscopy by ordinary catheterization method. Due to the deformation of the anatomical structure of the gastric cavity after liver transplantation, the catheterization process became more difficult, the operation time was prolonged, and the patient's discomfort increased. The three-chamber enteral nutrition tube was easy to slip off, and the final placement of the tube was in the gastric cavity. The abdominal X-ray showed that the tube was in the gastric cavity, which was a tube placement failure. Through the three-chamber enteral nutrition tube placement method of the utility model, the tube was placed again under endoscopy, and the biopsy forceps were used to clamp the binding wires one, two and three respectively and send them to the pylorus to the horizontal segment of the duodenum to the jejunum segment. After abdominal X-ray confirmation, the placement of the tube was in the jejunum segment, which was a successful placement.

[0037] Example 2

[0038] The patient was admitted to the hospital due to dizziness and lower limb weakness for more than 10 days. Due to the patient's coma, he could not eat orally. The three-chamber enteral nutrition tube was placed by the common catheterization method. The abdominal X-ray showed that it was in the stomach cavity, which was a failure of the catheterization. Through the three-chamber enteral nutrition tube placement method of the utility model, the tube was placed under endoscopy, and the biopsy forceps were used to clamp the binding wires one, two and three respectively and sent to the pylorus to the horizontal segment of the duodenum to the jejunum segment. After confirmation by abdominal X-ray, the tube was placed in the jejunum segment, which was a success.

[0039] Compared with the three-lumen enteral nutrition tube placement method without auxiliary binding wire, the three-lumen enteral nutrition tube placement method with three-wire assistance significantly improves the placement effect, has higher placement efficiency, shortens the operation time, is safe and effective, and can accurately determine the placement position and depth through abdominal X-ray examination to effectively achieve the treatment purpose and reduce the patient's discomfort. The three-lumen enteral nutrition tube is not easy to slip off, and it is not easy to cause reflux, aspiration, and retention.

[0040] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
