technical field

The utility model relates to the technical field of medical aids, in particular to a multifunctional oropharyngeal airway.

Background technique

Oropharyngeal ventilation tube is a non-tracheal tube ventilation tube, which is the simplest, most effective and economical airway aid. It is mainly used for patients with airway obstruction, especially in the airway management for critically ill patients. Falling back, blood, and sputum obstruct the airway, resulting in difficulty breathing and even suffocation. At this time, the vomit and secretions in the oral cavity and respiratory tract are generally removed by inserting the oropharyngeal airway, so that the critically ill patient can keep the airway open, and the oropharyngeal airway can also play a role in restricting the back of the tongue.

Chinese utility model patent CN205515881U discloses a fixable oropharyngeal airway, including a body, the body is composed of a pharyngeal end, a buffer section, an arc-shaped section and an oral end in sequence, and the end of the pharyngeal end is provided with an anti-damage section, an anti-damage section The length of the buffer section is 0.12-0.15cm, the outer surface of the buffer section is corrugated with a uniform concave-convex arc in radial section, the mouth end is sleeved with a connecting socket, and the distance L1 from the connecting socket to the mouth end is 2.5-2.8cm.
