Improved weak stimulation bionic oropharyngeal airway

Abstract

The invention discloses an improved weak-stimulation bionic oropharyngeal airway. The oropharyngeal airway is made of medical silica gel or medical elastomer material with a Shore hardness of 50-100, and silver ions, titanium dioxide, hydroxyl Apatite or bioactive molecules, or use layer-by-layer electrostatic self-assembly technology for antibacterial and antibacterial treatment. The oropharyngeal airway includes the main body of the oropharyngeal airway. The uvula support and concave tongue support, the two sides of the oropharyngeal airway body are designed with grooves to form an arc-shaped lumen, the middle part of the oropharyngeal airway body is a solid support, and the outer part of the oropharyngeal airway body is divided into the oropharyngeal airway body. Vertical soft lip protection sheet, the present invention sets concave uvula support and concave tongue support on the palatal surface and tongue surface of the oropharyngeal airway body, and the oropharyngeal airway is made of soft material, which is easier for patients to tolerance.

Description

technical field [0001] The invention relates to the field of medical aids, in particular to an improved weak stimulation bionic oropharyngeal airway. 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 concentrated, so stimulating the...

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
