Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a novel oropharyngeal airway catheter. Background Art

[0002] An oropharyngeal airway catheter is a non-tracheal ventilation duct, which is the simplest, effective and economical airway assistance device. It is widely used in the resuscitation after general anesthesia in clinical practice. In recent years, many domestic hospitals have applied it to clinical practice. At the same time, it can rescue unconscious patients without pharyngeal reflex, and effectively relieve the upper airway obstruction caused by posterior displacement of the tongue.

[0003] When the oropharyngeal airway catheter is connected to the breathing tube after being inserted, relying solely on the flange support is likely to result in unstable connection or even detachment, making it difficult to ensure the smooth flow of the patient's breathing air. At the same time, before inserting the oropharyngeal airway catheter, medical staff need to tilt the patient's head backward to open the airway for easy insertion. And after insertion, in order to avoid upper airway obstruction caused by posterior displacement of the tongue, it is necessary to continuously use a tongue depressor to press the tongue, which is rather laborious. Therefore, this application proposes a novel oropharyngeal airway catheter. Summary of the Utility Model

[0004] Based on this, in view of the above technical problems, it is necessary to provide a novel oropharyngeal airway catheter. Through the overall structural cooperation design, after the catheter is inserted into the patient's oropharynx, two arc-shaped hollow pressing frames are used to conveniently assist in increasing the supporting area of the upper flange, making the support of this catheter more stable. And it is convenient to hang two elastic hanging ear straps behind the patient's ears to further limit the position of the upper flange, greatly reducing the situation of unstable connection or even detachment of this catheter during use, thereby effectively ensuring the smooth flow of the patient's breathing air.
