PH AND TEMPERATURE MONITORING SYSTEM FOR LARYNGEAL MASK

摘要

Disclosed is a pH and temperature monitoring system for a laryngeal mask, the system comprising a laryngeal mask body (1) and a multifunctional signal processing display (8) which are cooperatively used with the laryngeal mask; and further comprising a laryngeal mask intelligent control system, and a pH display module, a temperature display module, a micro pH sensor probe and a micro temperature sensor probe which are each connected to the laryngeal mask intelligent control system, wherein the laryngeal mask intelligent control system, the pH display module and the temperature display module are all mounted inside the multifunctional signal processing display (8), the micro temperature sensor probe is mounted on the laryngeal mask body (1) on the back side of a mask bag (2), and the micro pH sensor probe is mounted in a linear groove (4) in the back side of the laryngeal mask body (1). The system is simple and practical, can achieve real-time monitoring of temperature and pH at the esophageal entrance of a patient, has high sensitivity, improves timely determination of gastric acid reflux, realizes timely early warning of gastric liquid reflux, reduces the risk of aspiration of the reflux fluid into the airway, and is safe and reliable.
