Description

Laryngeal mask with capsule pressure monitoring channel

Technical Field

Background

At present, although complications generated by the laryngeal mask during operation are obviously reduced compared with those generated by tracheal intubation, the pressure management of the laryngeal mask is determined by doctors according to experience and feel and is too dependent on human factors. As the balloon inflation rate approaches the maximum inflation rate, the stiffer the balloon, the less adaptable the various shapes of the pharynx, and there is another potential problem with ischemia of the oropharyngeal mucosa. When the laryngeal mask pressure against the pharynx exceeds the average capillary perfusion pressure, there is a risk of mucosal ischemia, possibly causing mucosal damage. The incidence of gastric distension also increases when the cap is over inflated. When the laryngeal mask cuff pressure is too low, or when there is a small laryngeal patient, the cuff may be displaced from the pharynx and leakage may occur. In the existing laryngeal mask manufacturing, most of the pressure indicating devices are used by combining an indicating mask bag, a joint with a valve and a one-way valve, and although the cost is low and the sealing performance is good, the pressure indicating devices cannot provide airway pressure of patients for medical staff in operation.
