This is a device for use in clinical, surgical and intro-operative patient core temperature monitoring, which utilizes an artificial airway to integrate a temperature probe, removing the need for an external cord for connecting to an external display unit, while the LMA is used for patients who are under general anesthesia. Consequently, accurate monitoring of core temperature can be achieved more easily. As a result, the medical complication and risk fact associated with other traditional ways of temperature monitoring is greatly reduced.
