Tracheal intubation stylet and improved methods of intubation and of lung function physiologic research and of functional pulmunologic diagnosis

摘要

An intubation device (1) utilizing an endotracheal tube (2) is presented. The device (1) comprises at least one temperature sensor (T1, T2, T3) located at a distal end (2A) of the endotracheal tube (2), which is intended for insertion into the patient's trachea opening, and a processor unit (8) located at opposite end of the tube (2). The sensor (T1, T2, T3) is capable of generating a temperature response to air circulation in the vicinity of the sensor (T1, T2, T3). The processor unit (8) receives this temperature sensor (T1, T2, T3) and analyzes it to generate data representative of a relative location of the distal end (2A) of the endotracheal tube (2) relative to the trachea opening. This data can be used for guiding a movement of the distal end (2A) of the endotracheal tube (2) into the trachea opening.
