Nasopharynx breather pipe

Abstract

The invention belongs to the technical field of intubation equipment, and discloses a nasopharynx breather pipe which is made of a soft rubber material. A fixing device is arranged at the exposed end of the nasopharynx breather pipe; the fixing device is used for fixing the nasopharynx breather pipe outside the nasal cavity. The front end of the nasopharynx breather pipe is beveled and blunt. The nasopharynx breather pipe is about 15 cm in length. The nasopharyngeal airway fixing device can fix the nasopharyngeal airway outside the nasal cavity, prevents the nasopharyngeal airway from sliding into the nasal cavity, guarantees the safety of a patient, can reduce the risk that the nasopharyngeal airway is easy to fall off or slide to the deep part of the respiratory tract in the use process, and is simple in structure, small in size and convenient to use. The nasopharyngeal airway solves the problem that the nasopharyngeal airway main body is not firmly fixed during use, and prevents the nasopharyngeal airway main body from loosening to cause friction between the outer sleeve and nasal cavity tissues, so that the damage to nasal cavity mucosa is reduced.

Description

technical field [0001] The invention belongs to the technical field of intubation equipment, and in particular relates to a nasopharyngeal ventilation tube. Background technique [0002] At present, the exposed end of the nasopharyngeal ventilation tube currently used clinically lacks a fixing device, which causes the nasopharyngeal ventilation tube to easily slip into the patient's nasal cavity during use, aggravating the patient's airway obstruction, and during the operation of sputum suction nursing for the patient more prone to slippage. Especially in male patients with larger nasal cavity, even the largest nasopharyngeal ventilation tube can easily cause the tube to slip into the patient's nasal cavity. [0003] In the prior art, the nasopharyngeal airway is usually fixed by tying a knot at the exposed end of the nasopharyngeal airway and fixing it on the patient's ear or using a 3M elastic bandage to fix the patient's nose. However, the above method is not comfortabl...

AI Technical Summary

Problems solved by technology

However, the above method is not comfortable enough, and the fixation effect is not good, and the risk of the nasopharyngeal ventilation tube falling out or slipping into the deep part of the respiratory tract is high during use

[0004] Through the above analysis, the existing problems and defects of the existing technology are: the existing nasopharyngeal ventilation tube fixation method is not comfortable enough, and the fixing effect is not good, and the nasopharyngeal ventilation tube is easy to fall out or slide into the deep part of the respiratory tract during use. Big

[0005] The difficulty of solving the above problems and defects is: the fixing device is disposable and cannot be used repeatedly. If it is used repeatedly, it will affect the fixing effect and virtually increase the economic burden of the patient; to allergic reactions, so how to choose environmentally friendly and non-allergenic materials is also a difficulty
