Description

Painless gastroscopy airway management system

technical field

The invention relates to the technical field of medical detection aids, in particular to a painless gastroscopic examination airway management system.

Background technique

Painless gastroscopy is to give a certain dose of short-acting anesthetics intravenously to help patients quickly enter a state of sedation and sleep, complete gastroscopy without awareness, and quickly wake up after the examination. After anesthesia, many patients, especially obese patients and patients with sleep apnea, will have severe airway obstruction or even unable to ventilate due to the back of the tongue and oropharyngeal muscles, resulting in insufficient oxygen supply and decreased oxygen saturation. Part of the airway obstruction can be solved by lifting the mandible, but some patients still need the intervention of upper airway ventilation tools to relieve it. When the hypoxia is severe, it will even threaten the life safety of the patient, and the process of handling the airway will seriously interfere or even The gastroscopy process needs to be suspended.

1) The mouthpiece itself adds weight to the back of the tongue. In order to prevent the patient's involuntary occlusion from causing damage to the gastroscope body, the mouthpiece is routinely placed when the patient is awake. This is a kind of tooth pad with a cavity in the middle for the gastroscope to pass through. The short tube, which has the disadvantage of pushing the tongue back, has little effect in patients who are awake and not at risk of airway obstruction, but in post-anesthesia and/or at risk of airway obstruction (eg, obesity), the anesthesia itself Both can cause the tongue to fall back and the pharyngeal muscles to relax, and the use of the mouthpiece pushes the tongue back, thereby aggravating the obstruction of the airway. In this case, the oropharyngeal airway can generally be used. The oropharyngeal airway is a clinical non-tracheal intubation non-invasive ventilation tube, which can push the tongue forward from the back of the tongue, reduce the back drop of the tongue, and open the airway. , to obtain effective ventilation, to avoid trachea blockage and suffocation caused by the tongue falling back during anesthesia. However, the ventilation tube inside the existing conventional oropharyngeal airway is too small to allow the gastroscope to pass, so it cannot be performed simultaneously with the gastroscopy, and cannot be inserted when the patient is awake because it causes gag reflex.

2) New tools have not completely solved the problem In order to solve the above problems, some people have made oropharyngeal airways that can pass gastroscopes, which solves the problem of airway obstruction to a certain extent, but there are also many shortcomings. a In the process of use, it was found that under ideal conditions, the gastroscope directly faces the opening of the glottis and esophagus after passing through the oropharyngeal airway, and it is impossible to explore the oropharynx and larynx. Moreover, it is not flexible enough to use. If this type of oropharyngeal airway is not placed before the examination, once the airway is blocked during the examination, the gastroscope must be withdrawn and placed again, which will seriously affect the examination process. b. The inner end of the tube passes through the larynx and connects with the trachea, and is inserted deeply, and then a gastroscope or a fiberoptic bronchoscope enters the human body through the oropharyngeal airway for examination, so that from the inside of the mouth to the larynx, these two endoscopes They are all in the oropharyngeal ventilation tube, so the condition of the larynx cannot be observed, and the lesions of the larynx cannot be examined. At the same time, this type of oropharyngeal ventilation tube is dedicated to establishing a ventilation tube, not specifically to establish a channel for endoscopy. It is not very suitable for gastroscopy. c The same disadvantage as the common oropharyngeal airway is that once the oropharyngeal airway is not properly placed, the only vent in the anterior segment will be blocked by soft tissue, resulting in no ventilation.

3) New tools are urgently needed To sum up, it is necessary to propose a special airway management system for painless gastroscopy. This airway management system should meet the following conditions: 1. It has the function of mouthpiece And oropharyngeal airway function, put the mouthpiece when the patient is awake, after anesthesia and after the start of gastroscopy, it can be considered whether to put in the oropharyngeal channel according to the patient's airway; 2. Flexible use, does not affect the process of gastroscopy, can be used in It is placed and removed during any process of gastroscopy, and does not occupy the channel with gastroscope; 3. It has the functions of oxygen ventilation and sputum suction, which facilitates oxygen supply through the oropharyngeal airway and suction of oropharyngeal secretions, and reduces the risk of secretion caused by inhalation of the trachea. Choking. 4. Porous design to prevent the main pipe opening from being blocked and unable to ventilate. In a word, its main purpose is to facilitate airway management after anesthesia while improving the efficiency of endoscopy and gastroscopy, and also to a large extent to improve the safety factor of patients.
