Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a nasogastric tube fixator. Background Technology

[0002] Nasogastric tubes are a primary means of providing nutrition to the body in cases of oral or gastrointestinal diseases. Inserted through the nasal cavity into the esophagus, they connect to the patient's stomach. Clinically, nasogastric tubes need to be secured externally to the nasal cavity. A common method involves cutting a piece of medical tape to a suitable size and wrapping one end around the tube below the nostril while the other end is wrapped around the skin on the bridge of the nose. This method requires experienced doctors or nurses, is complex, cumbersome, and unreliable, and is easily pulled off by unconscious or agitated patients. Furthermore, the medical tape on the tube below the nostril is easily soiled by nasal discharge and needs to be replaced.

[0003] Existing devices for fixing nasogastric tubes include those that pass the tube through one or two retaining rings and secure them with tape or straps. These devices require the tube to be passed through first, then adjusted for fixation. While the tube appears fixed, it's only peripherally restrained and can still be easily pulled out. Such devices are unreliable in clinical use and uncomfortable for patients. Other devices use nasal strips with connectors and adjusters on the outside of the nose. These are complex and also require passing the tube through first and then adjusting for position, making them cumbersome and unsuitable for clinical use. Therefore, there is an urgent clinical need for a simple and easy-to-use nasogastric tube fixator. Utility Model Content
