Description

Technical Field

[0001] This utility model relates to the field of medical technology, and more specifically, to a visible gastric tube. Background Technology

[0002] A nasogastric tube is a commonly used clinical medical device that can be inserted through the mouth or nose, passing through the pharynx and esophagus to reach the stomach. It helps to clean or extract gastric juices, perform gastrointestinal decompression, and deliver nutrition to critically ill patients.

[0003] Current gastric tube technology, lacking direct visualization devices, makes it difficult to observe the insertion process. This often results in the tube folding and knotting within the mouth and esophagus, hindering its insertion and leading to adverse consequences such as accidental aspiration into the airway, causing choking, shortness of breath, and even death, as well as delaying enteral nutrition. Furthermore, because current clinical gastric tube placement is mostly blind and difficult to visualize, it's impossible to determine the depth of insertion or whether the tube is actually in the stomach. This is particularly challenging for elderly patients, especially those with acute or critical illnesses or those under general anesthesia, due to factors such as poor cooperation, weak swallowing and cough reflexes, inability to swallow, or posterior displacement of the tongue.

[0004] Therefore, how to provide a visible gastric tube has become a technical problem that urgently needs to be solved in this field. Utility Model Content
