Description

An oropharyngeal airway that facilitates tube placement

technical field

The utility model belongs to the technical field of medical care appliances, in particular to an oropharyngeal airway which is convenient for pipe insertion.

Background technique

Oropharyngeal airway, also known as oropharyngeal airway, is a non-tracheal tube non-invasive ventilation tube, which can prevent the tongue from falling back, quickly open the airway, and establish a temporary artificial airway. Generally used for:

1. Maintain the patency of the upper airway: For anesthetized patients or comatose patients, due to the relaxation of the floor of the mouth and pharyngeal muscles that support the tongue to maintain the patency of the upper airway, the tongue and epiglottis can fall backwards into the posterior pharyngeal wall, resulting in upper airway obstruction. When properly inserted into the oropharyngeal airway, its front end can lift the tongue and epiglottis from the back wall of the pharynx, thereby preventing or treating upper airway obstruction. Compared with other methods of maintaining upper airway patency, such as chin lift, jaw lift, and endotracheal intubation, insertion of the oropharyngeal airway did not affect the stability of the patient's cervical spine.

2. Sputum suction: patients with pseudobulbar palsy, dysphagia, weak cough, long-term bedridden patients with pulmonary infection who do not need intubation and tracheotomy, repeated stimulation of sputum suction through the nasal cavity can easily damage the nasal mucosa, and sputum suction through the mouth The patient is easy to bite the suction tube and does not cooperate with it. After placing the oropharyngeal airway, the suction operation method is simple. It only needs to be inserted through the oral cavity to a depth of about 5-6 cm deeper than the nasal cavity. The phlegm in the deep part of the tract is coughed up to the upper respiratory tract and is conducive to suction.

3. Used as a tooth pad: In addition to maintaining the patency of the airway, the oropharyngeal airway can also be used as a tooth pad to prevent the patient from biting the tracheal tube inserted in the oral cavity. During seizures in epilepsy patients, the oropharyngeal airway not only maintains the patient's airway, but also prevents the patient from biting the tongue.

4. Other uses: assist in oropharyngeal suction; in the mask ventilation of some patients, the application of oropharyngeal airway helps to achieve mask sealing, such as edentulous patients; assist in the insertion of oropharyngeal and gastric tubes.

At present, the existing oropharyngeal airways have the following shortcomings:

In clinical patients sometimes need to insert gastric tubes, sputum suction tubes and other pipes, but in patients wearing oropharyngeal airways, the oral cavity is basically covered and occupied by the oropharyngeal airway, which is inconvenient for the insertion of the catheter, and the catheter cannot be fixed. , which caused troubles to the clinical treatment of patients, making this work extremely inconvenient.
