Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and more particularly to a visual 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 in incidence. Roux-Y anastomosis and Billroth II gastrointestinal anastomosis are commonly used surgical treatment procedures. In order to reduce the probability of duodenal stump leakage, bile-enteric anastomotic leakage or gastrointestinal anastomotic leakage, decompression operation is usually required at the input end of the anastomosis.

[0003] Gastrointestinal decompression is a commonly used nursing operation technique in general surgery. Its purpose is to drain gastric fluid and gas in the gastrointestinal tract, reduce abdominal distension and suture tension, and facilitate wound healing. It uses the principle of negative pressure suction to absorb gas and liquid accumulated in the gastrointestinal tract to reduce gastrointestinal pressure, improve gastrointestinal wall blood circulation, and help localize inflammation. It is a treatment method for draining gastric fluid and gas in the gastrointestinal tract. It requires the use of a feeding tube for decompression. The feeding tube can also help patients who cannot swallow to deliver necessary water and food in special circumstances. However, the current feeding tube can only provide a decompression effect, and cannot simultaneously deliver enteral nutrition to the output end of the anastomosis; the existing feeding tube cannot simultaneously have the functions of decompression and visualization; the flexibility of the camera adjustment of the existing feeding tube needs to be improved.

[0004] Therefore, how to provide a visual multi-purpose decompression feeding tube that can simultaneously meet the requirements of gastrointestinal decompression, intestinal nutrient delivery and visualization, and has more flexible camera viewing angle adjustment is an urgent problem that needs to be solved by technical personnel in this field. Summary of the invention

[0005] In view of this, the present invention provides a visualized multi-purpose decompression feeding tube, which aims to solve one of the problems in the above-mentioned background technology, while meeting the requirements of gastrointestinal decompression, intestinal nutrient delivery and visualization, and the camera angle adjustment is more flexible.
