[0003] The existing nasogastric tube, such as a nasogastric tube with the publication number CN220385465U, includes a nasogastric tube main body for sending liquid food, moisture, and medicinal food through the nasal cavity to the patient's stomach. An internal visual auxiliary tube is provided inside it for assisting the accurate insertion of the nasogastric tube main body in the path. A fixing component for fixing the nasogastric tube main body is provided on the surface of the nasogastric tube main body; the visual auxiliary tube includes an inner tube arranged in the inner cavity of the nasogastric tube main body, and a micro camera electrically connected to a display screen is installed at one end of the inner tube; by adopting a split structure for the nasogastric tube main body and the visual auxiliary tube, the visual auxiliary tube can be taken out from the inner cavity of the nasogastric tube main body for disinfection, facilitating secondary use; at the same time, a connecting piece is added between the fixing clip and the strap, so that the fixing clip and the strap are in a split structure. When the strap head fails due to long-term use, the strap can be quickly removed from the fixing clip for separate replacement.

[0004] However, at present, the nasogastric tube is fixed by a strap. On the one hand, its service life is limited. On the other hand, the strap is a tightening type fixing structure, which is easy to cause discomfort to the patient. Therefore, we propose a restraint device for preventing the nasogastric tube from falling off to solve the problems raised above. Content of the Utility Model
