Abstract

The invention relates to a deep oxygen supply type nasopharyngeal airway, and belongs to the technical field of medical instruments. The deep oxygen supply type nasopharyngeal airway comprises a main ventilation pipe and an extension pipe. A main ventilation chamber and a side chamber are arranged in the main ventilation pipe. A bell mouth is formed in the tail end of the main ventilation pipe. The outer wall of the lower end of the bell mouth is sleeved with a rotatable fixing wing. The fixing wing is provided with a through hole, and straps are arranged on the two side edges of the fixing wing. An oxygen source connector communicates with one end of the extension pipe, and the other end of the extension pipe communicates with the tail end of the side chamber. The deep oxygen supply type nasopharyngeal airway has a respiratory tract obstruction eliminating function and a deep oxygen supply function, and by adding the fixing wing, the problem that the deep oxygen supply type nasopharyngeal airway is hard to fix in clinical use is solved.

Description

technical field [0001] The invention relates to a deep oxygen supply type nasopharyngeal ventilation tube, which belongs to the technical field of medical instruments. Background technique [0002] In the clinical practice of respiratory airway obstruction caused by any reason, opening the airway is the primary measure. The nasopharyngeal ventilation tube is inserted into the throat through the unilateral nasal cavity to drain the soft tissue of the pharynx cavity, relieve or relieve the patient's upper airway obstruction or obstruction, To achieve the purpose of establishing an artificial airway. [0003] The traditional artificial ventilation tube is a single-lumen tube. During use, when the medical staff moves the patient or the patient coughs, it will cause the nasopharyngeal ventilation tube to shift or cough out, and the single-lumen tube is too bent. It is more prone to bending and closing. [0004] When a patient suffers from hypoxia, the conventional clinica...
