Description

A new bionic oropharyngeal airway with weak stimulation

technical field

The utility model relates to the field of medical auxiliary tools, in particular to a novel weak-stimulation bionic oropharyngeal airway.

Background technique

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:

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;

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 tongue median groove and 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 maxillary 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.

3. The traditional oropharyngeal airway cannot be intubated directly through the airway in an emergency, but the airway needs to be pulled out, and then the trachea is intubated, which wastes precious first aid time and causes secondary harm to the patient. injury.

Utility model content

The utility model provides a novel weak stimulation bionic oropharyngeal airway. The oropharyngeal airway is made of medical silica gel or medical elastomer material, and the palate surface and tongue surface of the oropharyngeal airway body are respectively provided with concave uvula supports. And concave tongue rest, make it easier for patients to tolerate.

The technical scheme that the utility model adopts is:

A new weak stimulation bionic oropharyngeal airway, including the oropharyngeal airway body, the palatal surface and tongue surface of the oropharyngeal airway body are concave uvula support and concave tongue support respectively, and the two sides of the oropharyngeal airway body are Arc-shaped lumen, the middle part of the oropharyngeal airway body is a solid support body, and the outer part of the mouth of the oropharyngeal airway body is divided into a lip protection sheet perpendicular to the oropharyngeal airway.

Preferably, the oropharyngeal airway is made of medical silicone or medical elastic material with a Shore hardness of 50-100.

Preferably, the body of the oropharyngeal airway is treated with silver ions, titanium dioxide, hydroxyapatite or bioactive molecules for antibacterial and antibacterial treatment, or with layer-by-layer electrostatic self-assembly technology for antibacterial and antibacterial treatment.

Furthermore, the concave uvula support at the rear end of the oropharyngeal airway and the concave lingual support are provided with natural continuous smooth and thickened tooth pads on the palate and tongue near the lip protection sheet.

Preferably, the part of the oropharyngeal airway body that extends into the oropharynx has a circular arc shape that adapts to the anatomical radian of the oropharynx.

Preferably, the lip protection sheet is arc-shaped.

The front end of the oropharyngeal airway adopts a flat arc-shaped design to reduce damage to the soft tissue of the oropharynx during and after the placement of the oropharyngeal airway.

The beneficial effects of the utility model are:

1. The body of the oropharyngeal airway is made of medical silicone or medical elastomer material with a Shore hardness of 50-100, which is soft and tough, and causes little damage to the soft tissue of the oropharynx during and after insertion. And the body material of the oropharyngeal airway adopts silver ions, titanium dioxide, hydroxyapatite or bioactive molecules, or adopts layer-by-layer electrostatic self-assembly technology for antibacterial and antibacterial treatment, which can effectively prevent the growth and reproduction of oropharyngeal bacteria during use .

2. The palatal surface and tongue surface of the oropharyngeal airway body are respectively concave uvula support and concave tongue support to reduce stimulation to the uvula and tongue.

3. The tooth pad part protects the body of the oropharyngeal airway from being bitten and deformed by the teeth, and also protects the teeth from damage.

4. The part of the oropharyngeal airway body extending into the oropharynx is a circular arc adapted to the anatomical radian of the oropharynx, so as to reduce the stimulation to the soft tissues of the oropharynx.

5. The front end of the oropharyngeal airway adopts a flat circular arc design to reduce the damage to the soft tissue of the oropharynx during and after the airway is placed.

6. Both sides of the oropharyngeal airway body are arc-shaped lumens. On the one hand, after tracheal intubation, the endotracheal tube can be inserted into the arc-shaped lumen on one side of the oropharyngeal airway body to fix and protect the endotracheal tube. On the other hand, before tracheal intubation, the oropharyngeal airway can also be placed in advance, and then the tracheal intubation can be performed through the curved lumens on both sides of the oropharyngeal airway using a visualization device or a blind detection device. Of course, the curved lumen can also be used to conveniently suck sputum or insert a gastric tube.

7. On the one hand, the lip protection sheet can protect the upper and lower lips from being damaged by medical operations; on the other hand, the lip protection sheet can be fixed on the face with adhesive tape to prevent the oropharyngeal airway body from prolapse.

8. In case of emergency, the visualization device or blind detection device can be used to perform tracheal intubation directly through the arc-shaped lumen of the oropharyngeal airway, instead of pulling out the oropharyngeal airway first like the traditional oropharyngeal airway. Endotracheal intubation again saves valuable emergency time and avoids secondary injury to the patient.
