Description

Multifunctional laryngeal mask

Technical Field

The utility model belongs to the technical field of medical appliances, and particularly relates to a multifunctional laryngeal mask.

Background

During general anesthesia operation, a safe airway can be established by using the laryngeal mask, and the patient can breathe spontaneously through the laryngeal mask and can also control ventilation. Laryngeal masks generally include a airway tube, a drainage tube, and an inflatable cuff disposed at the distal end of the airway tube. First, in order to match the inflatable cuff to the shape of the human perilaryngeal tissue, the inflatable cuff is typically configured as an oval. However, the oval cuff still cannot be completely matched with the human laryngeal peri-tissue, and the risk of air leakage exists. Secondly, in the prior art, the drainage port of the drainage tube is only arranged at the middle position of the lower end of the inflatable cuff, and the back surface of the inflatable cuff is opposite to the oropharynx of a human body, so that secretion and reflux of the oropharynx cavity cannot be cleared away in time, and erroneous suction is easily caused. Third, intra-operative body temperature real-time monitoring can significantly improve anesthesia controllability and safety, and the existing multifunctional laryngeal mask lacks perioperative body temperature monitoring function. Accordingly, it is desirable to provide a multi-functional laryngeal mask.
