[0002] Nasal feeding refers to the artificial insertion of a gastric tube through the nasal cavity into the esophagus under special circumstances. First, the food is pureed with a grinder, and a large syringe is connected to the large food injection port below the gastric tube connector. After being firmly connected, the piston of the push rod is manually pressurized to inject water and food into the patient's stomach, helping patients who cannot swallow independently to obtain water and food, and maintaining the body's metabolism, weight, and nutrition. The syringe is an important instrument during nasal feeding.
