Weak stimulation tracheal catheter fixed type oropharynx airway

Abstract

The invention discloses a weak stimulation tracheal catheter fixed type oropharynx airway. The oropharynx airway is made of medical silica-gel or medical elastomer materials with Shore hardness being 50-100, and bacteria resistance and bacteriostasis treatment is conducted by adopting silver ions or titanium dioxide or hydroxyapatite or bioactive molecules, or adopting the layer-by-layer electrostatic self-assembling technique. The oropharynx airway comprises an oropharynx airway body; the jaw face and the lingual surface of the oropharynx airway body are separately a concave uvula support and a concave tongue support; both sides of the oropharynx airway body are arc tube chambers through a groove design; a solid supporting body is arranged in the middle of the oropharynx airway body; and a soft lip protection piece perpendicular to the oropharynx airway is arranged outside an oropharynx airway body opening. The concave uvula support and the concave tongue support are separately arranged on the jaw face and the lingual surface of the oropharynx airway body, and the oropharynx airway is made of soft materials, so that a patient easily tolerates the oropharynx airway.

Description

technical field [0001] The invention relates to the field of medical auxiliary tools, in particular to a fixed oropharyngeal airway with weak stimulation endotracheal tube. Background technique [0002] The oropharyngeal airway is an auxiliary ventilation device. It can be inserted into the pharynx through the oral cavity, and the base of the tongue can be pushed forward by the support of the airway tube, so as to expand the pharyngeal cavity and improve the symptoms caused by tongue falling backward, oropharyngeal stenosis or secretions. Improve ventilation due to airway obstruction. Traditional oropharyngeal airways have the following problems: [0003] 1. The traditional oropharyngeal airway is made of hard material, which causes great damage to the soft tissue of the oropharynx during and after insertion; [0004] 2. Since the tongue is rich in nerve endings, especially in the median tongue groove and boundary groove, the distribution of nerve endings is more concentra...

AI Technical Summary

Problems solved by technology

[0003] 1. The traditional oropharyngeal airway is made of hard material, which causes great damage to the soft tissue of the oropharynx during and after insertion;

[0004] 2. Since the tongue is rich in nerve endings, especially in the median groove of the tongue and the boundary groove, the distribution of nerve endings is more concentrated, so stimulating the median groove of the tongue and the boundary groove will cause strong nausea and discomfort, and the uvula will also There are abundant nerve endings, so stimulating the uvula will also cause strong nausea and discomfort. The tongue part of the traditional oropharyngeal airway is just pressed in the middle of the tongue, and the middle of the tongue is the median groove of the tongue and the boundary groove, and the palatal part of the airway just presses on the uvula. The distribution of nerve endings in these positions is extremely rich, and they respond strongly to stimuli. Therefore, when the traditional oropharyngeal airway is placed, the patient feels unbearable nausea and discomfort. by

[0005] 3. The traditional oropharyngeal airway cannot be used for tracheal intubation directly through the airway in an emergency, but the airway needs to be pulled out and the trachea intubated again, which wastes precious first aid time and causes secondary harm to the patient. secondary injury
