Description

Bendable visible naso-intestinal stomach tube

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to visual naso-intestinal stomach tube of flexible.

Background

The tube feeding route is the first route for enteral nutrition to be taken by patients who normally function in the gastrointestinal tract, but who have conditions where oral ingestion is not possible or insufficient. As early as 1790, Hunter fed patients with dysphagia via the nasogastric route. After years of development, the tube feeding technology is mature. The nasogastric route is an important route for Enteral Nutrition (EN) therapy and can meet the requirement of enteral nutrition of patients; nasogastric tubes have applications as a simple and effective enteral route in almost all clinical departments in large and medium-sized hospitals in the country. However, at present, the placement of the nasogastric and intestinal tube still needs to be carried out by means of an endoscope, an X-ray machine or blind insertion, and most of the placement is blind insertion. Because many ditches in the middle of the intestine are limited, especially at the pylorus, the pylorus is in an s-bend shape, the operation is difficult, the investment of manpower and material resources of the doctor and the patient is greatly increased by the factors, and the medical risk of the patient in the process of putting the tube is also increased. At present, some visible nasogastric-intestinal tubes (patent number CN 212090251U, CN 213373855U) with a camera with a light source are arranged at the front end of a catheter, and although visible tube placement is realized, the nasogastric-intestinal tubes cannot be bent, the nasogastric-intestinal tubes cannot be smoothly and accurately inserted to jejunums or required parts through pylorus and duodenum of a gastric cavity, the production process requirement is high, the cost is high, and after tube placement, the camera assembly cannot be moved out and is always left in vivo for 50 days or even longer, and due to strong acidity of gastric juice, substances such as curing glue of the camera are easily corroded, stimulation effect can be generated on digestive tracts, other potential hazards such as exceeding of heavy metals can be caused, and the visible nasogastric-intestinal-tube is not beneficial to popularization. To this end, we propose a bendable visible naso-intestinal gastric tube.
