Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a nasogastric tube with an elastic supporting structure.
Background
The stomach tube is a nutrient component which helps patients who cannot swallow to convey human body needs under special conditions, and is divided into an oral stomach tube and a nasal stomach tube, wherein the nasal stomach tube is inserted through nostrils, passes through pharynx and passes through esophagus to reach stomach. Because the exposed portion (the portion located outside the patient) of the nasogastric tube is long, the nasogastric tube is easy to fall out, so that a medical adhesive tape is generally used to paste and fix the nasogastric tube on the face of the patient, for example, on the nose or the cheek of the patient. However, the skin of the face of the patient can secrete secretion such as grease, the viscosity of the medical adhesive tape can be reduced, and the medical adhesive tape can loosen and fall off at intervals and needs to be replaced frequently; furthermore, the use of medical tapes is prone to skin allergies for patients who are partially sensitive to skin. In addition, because the contact area of the nasogastric tube and the nasal cavity of the patient is small, the nasal skin of the patient with long-term intubation is easy to be crushed.
Disclosure of utility model
