Description
Technical Field
The utility model relates to the technical field of medical machinery, in particular to an improved oropharynx air duct for portable general anesthesia.
Background
General anesthesia refers to that an anesthetic enters a patient body through muscle or intravenous injection and respiratory inhalation to temporarily inhibit a central nervous system, and is clinically characterized by unconsciousness, reflex inhibition, general analgesia, amnesia and skeletal muscle relaxation. According to different airway management modes during general anesthesia, two mechanical ventilation modes can be divided into a non-invasive mode and an invasive mode. Most anesthetists use the method of intubation of the trachea in invasive positive airway pressure for airway management during general anesthesia. Invasive positive pressure ventilation requires the establishment of an artificial airway, mechanical ventilation is performed by connecting a respirator in a manner of tracheotomy, oral intubation, transnasal intubation or the like, and most of airway management in general anesthesia surgery is completed by using the oral intubation. The types of common auxiliary tools for tracheal intubation include laryngoscopes, soft lenses and the like. When a laryngoscope is used for intubation operation, the laryngoscope is not only easy to damage the body structures such as incisors, tongue roots, epiglottis and the like, but also has the conditions of accelerated heart rate and raised blood pressure due to great stimulation to patients, and is not beneficial to maintaining the circulation stability and the anesthesia depth of the patients; when the video soft lens is used for intubation, the video soft lens lacks a guiding effect in the oral cavity and is easy to lose direction, and under the combined action of general anesthetic and muscle relaxant, buccolingual muscle of a patient is relaxed, pharyngeal muscle tension disappears, tongue tenesmus are caused, tongue root blocks the mouth floor, and a very narrow or even completely blocked area is formed together with a soft palate, so that the advance of the soft lens is blocked, and the trachea intubation is too long or the intubation fails.
In conclusion, the development and design of the improved oropharyngeal airway which can meet the requirement of the physiological structure of the throat of a human body during general anesthesia, plays a guiding role for the tracheal intubation and is easy to take out from the oral cavity has profound significance and great application prospect.
