The embodiment is substantially as shown in figures 1, 2 and 3 of the accompanying drawings: a multi-lumen catheter for enteral nutrition comprises a catheter body 1, the length of the catheter body 1 is 50-70cm, and the length of the catheter body 1 is 60cm in the embodiment. The diameter of the conduit is 10F-12F; the catheter comprises a catheter body 1, a fixing part, a main chamber 3 and a supporting rod, wherein the fixing part is arranged at one end of the catheter body 1, the main chamber 3 is arranged in the catheter body 1, and the supporting rod in the prior art is adopted. The main cavity 3 is positioned in the middle of the catheter body 1, and the plurality of branch cavities are respectively positioned outside the main cavity; the plurality of branch chambers include a drainage chamber 4, a particle chamber 10 and a balloon chamber 11, and radioactive particles 13 are arranged in the particle chamber 10. The quantity of particle chamber is two in this embodiment, and two particle chambers set up along main cavity symmetry to utilize the particle to carry out more effective, the illumination of bigger area. The length of the drainage chamber 4 and the particle chamber 10 is 8-10cm respectively, and the pipe diameter of the drainage chamber 4 and the particle chamber 10 is at least 4F, preferably 4F. The distance between the ends of the drainage chamber 4 and the particle chamber 10 and the tail end of the catheter (i.e. the end of the catheter remote from the patient) is 25cm, so that the ends of the drainage chamber and the particle chamber are located just at the lower "ampulla" of the common bile duct. The fixation part in this embodiment is a spherical balloon 2, the spherical balloon 2 being in communication with a balloon chamber 11. The embodiment also comprises a drainage tube 5 and a nutrient solution tube, wherein the drainage tube 5 is communicated with the drainage cavity 4, the end part of the drainage cavity 4 is provided with a drainage port 14, and the outer side surface of the drainage tube is provided with at least one drainage hole. The nutrient solution pipe is communicated with the nutrient solution chamber 12, and the end part of the nutrient solution chamber 12 is provided with a nutrient solution outlet 15.

The end part of the catheter body 1 far away from the spherical air bag 2 is provided with a covering part, specifically, the covering part in the embodiment comprises a cover body 8, a connecting belt 9 and a connecting ring 7, and the connecting belt 9 is a connecting belt 9 made of plastic materials and has certain plasticity. Two ends of the connecting belt 9 are respectively connected with the upper part of the cover body 8 and the connecting ring 7 in a gluing way. The end part of the nutrient canal 6 is provided with a limiting groove used for limiting the connecting ring 7, and the connecting ring 7 is positioned in the limiting groove.

The specific implementation process is as follows: under the condition of no-bile duct expansion, the scheme is matched with the gastroenterology department, the RECP balloon catheter technology is adopted, the bile duct is automatically expanded by the balloon, then one end of one cavity of the drainage tube 5, which is provided with the spherical air bag 2, extends into the ampulla of Wharton's jelly-fish, and the spherical air bag 2 is inflated through the balloon cavity 11, so that the spherical air bag 2 is expanded and is propped against a single tube of a patient, the purpose of fixing the catheter is achieved, and the position of the catheter is prevented from moving. The catheter also has a drainage chamber 4, a nutrient solution chamber 12 and a particle chamber 10. Under original state, 8 lids of lid are in nutrition also the pipe end seals nutrient solution pipe tip, when needs provide nutrition to patient, open lid 8, the setting of connecting ring 7 and connecting band 9 can prevent that lid 8 from dropping, then pour into the nutrient solution through nutrient solution pipe, nutrient solution manages to support the liquid pipe and get into in the nutrient solution cavity 12 back again from nutrient solution export 15 outflow, it supplyes the nutrition for patient to get into patient's internal, not only solve the problem that the patient did not eat, can also solve the jaundice problem of obstructive. The conduit is provided with a main chamber 3 in the middle for guidance. Under the condition that a patient is blocked by a bile duct, the scheme directly adopts the PTCD technology to enable the multi-cavity nutrition tube to pass through the horizontal part of the duodenum and reach the distal jejunum of the duodenal flexor ligament, and the catheter is fixed. The method can solve the problem of nutrition deficiency caused by incapability of eating food of patients, and can also solve the problem of biliary tract drainage.

Example two

Referring to fig. 4, the difference between this embodiment and the first embodiment is that the fixing portion includes a fixing wire 16, the fixing wire 16 in this embodiment is an acrylic yarn, and one end of the fixing wire 16 is connected to the end of the catheter.

Under the condition of no-biliary duct expansion, the scheme is matched with the gastroenterology department, a balloon catheter is adopted under an endoscope to carry out ERCP technology, a common bile duct and an intrahepatic bile duct are reversely expanded by the balloon catheter, then the nutrition tube is percutaneously penetrated through the liver and enters the horizontal part of the duodenum through the lower end of the common bile duct by adopting PTCD technology to reach the far side of the flexor duodenum, and before the position of the nutrition tube is fixed, the tail ends of a drainage cavity and a particle cavity are determined to be positioned at the lower end of the common bile duct and do not exceed the ampulla part as the criterion through an X-ray opaque mark point of the nutrition tube.
