AI Technical Summary
Technical Problem
Existing nasogastric tubes are prone to bending and closing due to their flexibility, preventing the infusion of nutrient solution, causing patient discomfort, and requiring frequent reinsertion.
Method used
It adopts a hydrophilic coating and support wire structure, combined with a fixing component. The hydrophilic coating absorbs water and expands before use to form a hydrogel layer to reduce friction, the support wire increases stability, and the fixing component is fixed by a skin-friendly material patch to avoid compression.
Benefits of technology
It effectively reduces friction between the nasogastric tube and the patient's nasal cavity and throat, increases insertion stability, prevents internal closure, reduces patient discomfort, and improves ease of operation.

Abstract
The utility model provides an ultra-smooth nasal feeding tube with a hydrophilic coating, which belongs to the field of medical instruments and comprises a nasal feeding tube body, one end of the nasal feeding tube body is in a pointed cone shape, a hydrophilic component is arranged on one side of the nasal feeding tube body, and a fixing component is arranged outside the nasal feeding tube body. According to the hydrophilic nasal feeding tube, the hydrophilic assembly is arranged, so that the effect of supporting the nasal feeding tube body is achieved; before the nasal feeding tube is used, the nasal feeding tube body is placed in normal saline to be soaked for 30 seconds, the hydrophilic coating made of polyvinylpyrrolidone absorbs water and expands to form the hydrogel layer, when the nasal feeding tube is inserted into the nasal cavity and the throat of a patient, the formed hydrogel layer can greatly reduce the friction coefficient between the outer wall of the nasal feeding tube body and the nasal cavity and the throat of the patient, and discomfort of the patient is reduced; meanwhile, the supporting wire made of the nickel-titanium alloy can improve the stability of the nasal feeding tube body in the bending process, and the situation that the inner cavity of the nasal feeding tube body is completely closed when the patient moves is avoided.
