Description

Nutrient support device for anastomotic stoma fistula after esophagus operation Technical Field The utility model relates to the technical field of medical appliances, in particular to a nutrition support device for an esophageal postoperative anastomotic stoma fistula. Background Esophageal cancer resection is suitable for the conditions that the esophagus or cardiac cancer is diagnosed at an earlier stage, and the lower esophageal cancer is partially diagnosed at a third stage, the lesion length is within 5cm, the lesion length is good in general, the lesion length is good, the lesion length is free from distant metastasis, the patients with serious damage to heart, lung, liver and kidney functions or other operation contraindications are avoided, the patients with the advanced age of 70 years or older should be strictly selected, and a catheter is usually required to be used for sucking and decompressing anastomotic fistula liquid at the anastomotic stoma after the esophageal cancer operation. The existing decompression operation is usually performed by inserting a catheter into a human body, and because the catheter is internally provided with only one anastomotic stoma fistula decompression passage, a small amount of nutrient solution is injected into the fistula when nutrient solution is conveyed, so that the anastomotic stoma of a patient is infected, the recovery efficiency of the patient is reduced, and inconvenience is brought to the nutrient solution conveying work of the patient. According to the technical scheme, the gastric tube is characterized in that CN203154559U is used for providing a gastric decompression tube for preventing esophageal cancer, cardiac cancer postoperative anastomotic fistula and stenosis, the front end of the gastric tube is provided with four side holes, the rear end of the gastric tube is connected with a plug, a gastric tube body development line is marked on the tube body, the middle lower end of the gastric tube is provided with an air bag, an air bag wall development line is arranged on the air bag wall, an air pipe is attached to the inner wall of the gastric tube, the front end of the air pipe is communicated with the air bag through the wall of the gastric tube, the rear end of the air pipe is led out from the wall of the gastric tube, one side of the air pipe is connected with an inflation valve, and the other side of the air pipe is connected with a pressure indicator through the pressure measuring tube and the two-way valve. The device is used for monitoring the expansion degree of the air bag and displaying the magnitude of the blocked force when the air bag expands, so that the treatment scheme can be conveniently and timely adjusted, and the situation that the anastomotic stoma is torn due to blind inflation is avoided. The air bag is dumbbell-shaped when full of air, and the waist of the air bag is just clamped at the center of the anastomotic stoma or the narrow part at the moment, so that the air bag is not easy to slide. The utility model has drainage function, can prevent various reflux digestive liquids from soaking and corroding the anastomotic stoma of the esophagus, prevent anastomotic fistula, support the anastomotic stoma and is beneficial to healing of the anastomotic stoma. According to the gastrointestinal decompression tube described above, since there is only one anastomotic stoma fistula decompression path in the catheter, a small amount of nutrient solution is injected into the stoma during nutrient solution delivery, which results in infection of the anastomotic stoma of a patient, reduces recovery efficiency of the patient, and brings inconvenience to nutrient solution delivery of the patient, so that a nutrition support apparatus for an anastomotic stoma fistula after esophageal operation is needed. Disclosure of utility model The utility model aims to provide a nutrition support device for an anastomotic stoma fistula after oesophageal surgery, which completely isolates a decompression passage of the anastomotic stoma fistula in a catheter from a nutrition support passage through the matching of a nutrition injection passage and a catheter inlet, so that nutrient solution can be injected into the stomach and intestine through an independent nutrition injection passage, and the nutrient solution is prevented from being injected into the stoma, thereby avoiding infection to an anastomotic stoma of a patient, improving recovery efficiency of the patient, and providing convenience for nutrient solution conveying work of the patient so as to solve the problems proposed in the background art. The nutrition support device for the esophageal postoperative anastomotic stoma fistula comprises a catheter main body, a bifurcation part, a guide wire, an adjusting component for adjusting the height of an inflation valve and a moving structure for assisting in moving of a balloon, wherein a nutrition injection channel is formed in the top end of the
