INTEGRATED SMART LARYNGEAL MASK HAVING PH AND TEMPERATURE MONITORING FUNCTIONS

摘要

An integrated smart laryngeal mask having pH and temperature monitoring functions, comprising a mask body (1), a mask bag (2), and a ventilation lumen (3); the mask body (1) is provided with a linear groove (4), a signal transmission line lumen (5) and a drainage lumen (6) are provided in the mask body (1), and are respectively in communication with a temperature sensor probe micro cavity (51) on the mask body (1), and a pH sensor probe micro cavity (52) and a drainage port (61) provided in the linear groove (4); one end of a pH sensor signal transmission line and one end of a temperature sensor signal transmission line provided in the signal transmission line lumen (5) are respectively connected to a micro pH sensor probe and a micro temperature sensor probe, and the other ends are both connected to a multi-functional signal processing display (8). The integrated smart laryngeal mask is simple and practical, and can achieve real-time monitoring of the temperature and acidity or alkalinity at the entrance of the esophagus of a patient, has high sensitivity, improves the timeliness of the determination of gastric acid reflux, achieves timely warning of the behavior of gastric juice reflux, reduces the risk of the refluxed juice being accidentally sucked into the airway, and is safe and reliable.
