An oropharyngeal airway capable of esophageal occlusion and tracheal intubation guidance

Abstract

The invention provides an oropharynx air passage capable of realizing esophagus blockage and trachea cannula guiding. The oropharynx air passage comprises a trachea cannula guiding groove, wherein the trachea cannula guiding groove is composed of a groove body and a groove wall; the groove wall is provided with an esophagus catheter in a penetrating manner; the far end of the trachea cannula guiding groove is provided with an oropharynx air passage air bag; the far end of the esophagus catheter is provided with an esophagus catheter air bag; the groove wall of the trachea cannula guiding groove is wrapped and sealed by the oropharynx air passage air bag; the esophagus catheter is wrapped and sealed by the esophagus catheter air bag; the groove wall of the trachea cannula guiding groove is further provided with an oropharynx air passage air bag injection pipe and an esophagus catheter air bag injection pipe in a penetrating manner. According to the oropharynx air passage, the trachea cannula guiding groove is taken as a positioning and guiding device of the trachea cannula during anesthesia induction, and also can be taken as the oropharynx air passage for oropharynx aeration when a trachea catheter is pulled out, and the operation is simple and convenient, so that the trachea cannula operation is simple and convenient and easy to implement, and can effectively ensure the safety of patients.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an oropharyngeal airway that can realize esophageal blockage and tracheal intubation guidance, and is mainly used in clinical anesthesia and emergency tracheal intubation, oropharyngeal ventilation, esophageal blockage, and anesthesia recovery Airway management during the procedure. Background technique [0002] For a long time, clinical anesthesia and emergency tracheal intubation have mainly relied on techniques such as laryngoscopy and light sticks. In recent decades, the visualization of endotracheal intubation technology has developed rapidly, which facilitates the guidance of endotracheal intubation. However, in the actual clinical anesthesia and emergency work, there are still many problems in the use of tracheal intubation, which brings trouble and constraints to the operation of medical workers.

AI Technical Summary

Problems solved by technology

However, in the actual clinical anesthesia and emergency work, there are still many problems in the use of tracheal intubation, which brings troubles and constraints to the operation of medical workers.

[0003] First of all, the tracheal intubation technology with the help of laryngoscope, light wand, fiberoptic bronchoscope, etc. is cumbersome and complicated in the process of clinical anesthesia application

It can also lead to complications such as oral mucosal damage, bleeding, loose teeth, and loss of teeth.

Especially in the process of emergency airway and difficult airway management, it is time-consuming and labor-intensive, which is not conducive to the rescue of patients

[0004] Secondly, in the process of recovery from anesthesia, it is often encountered that the patient's spontaneous breathing cannot meet the standard and the endotracheal tube cannot be removed. However, the stimulation of the trachea by the endotracheal tube will cause the patient's blood pressure to increase and heart rate to increase, threatening the patient's life safety.

[0005] In addition, in the rescue and anesthesia process of patients with full stomach and intestinal obstruction in the emergency department, reflux aspiration and airway obstruction caused by vomiting of gastric contents have not been effectively resolved
