Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional visual catheter placement flexible endoscope. Background Technology

[0002] Enteral nutrition support is widely used in clinical practice because it can prevent patients from having insufficient intake due to various diseases and is more in line with human physiological functions than parenteral nutrition. Common methods of enteral nutrition support include nasogastric tubes and nasoenteric tubes. Given the potential for local mucosal damage, increased aspiration due to gastroesophageal reflux, and difficulty in gastric emptying caused by insufficient gastric motility resulting from long-term nasogastric tube placement, nasoenteric tubes have become an important option. However, due to the long and winding path of jejunal tube placement, blind insertion of nasoenteric tubes makes it difficult to accurately determine the direction, position, and length of the tube; it relies on the operator's experience and feel, and requires abdominal X-ray or ultrasound to pinpoint the final location, resulting in a low success rate and being time-consuming and labor-intensive. Endoscopic nasoenteric tube placement is also a complex procedure involving different departments, causing patient discomfort, increasing patient suffering, and adding to the workload of the medical team.
