Description

Technical Field

[0001] The utility model belongs to the technical field of clinical use devices, in particular to an improved oropharyngeal airway fixing device. Background Art

[0002] The oropharyngeal airway, also known as the oropharyngeal vent, is a non-invasive ventilation tube that is not a tracheal tube. Its main function is to prevent the tongue from falling back, quickly open the airway, and establish a temporary artificial airway. This airway is usually used for comatose patients to prevent their tongue root from falling back and blocking the airway, and to help suction sputum and keep the airway open. It can also be used as a dental pad during tracheal intubation to prevent the patient's teeth from clenching and compressing the tracheal tube.

[0003] The oropharyngeal airway is usually made of rubber or plastic, but can also be made of metal or other elastic materials. Its structure includes the wing edge, the tooth pad part and the pharyngeal curvature. The width of the occlusal part where the tooth pad part contacts the teeth should be wide enough to contact two to three teeth to ensure that the occlusal pressure of the teeth can be evenly distributed. The design of the pharyngeal curvature makes the curvature of its inner end of the mouth adapt to the anatomical structure of the mouth, tongue and posterior pharynx.

[0004] When using an oropharyngeal airway, it is necessary to select the appropriate model and operate according to the patient's specific situation.

[0005] However, under the existing technology, after critically ill neurosurgery patients use oropharyngeal airways, the oropharyngeal airways often move in the oral cavity due to the patients' irritability, non-cooperation or lack of teeth, and cannot be fixed behind the tongue root or even fall off.

[0006] Therefore, a new solution to the above problems needs to be proposed. Utility Model Content
