Outline of Final Research Achievements

The purpose of this study was to establish a new methodology for sensing the patient's respiratory flow and guiding the tracheal tube into the airway during tracheal intubation, and to develop a device that can be applied clinically. To realize airflow measurement in the small space of the oral cavity, we developed a sensor with a diameter of only a few hundred micrometers using MEMS (Micro-Electro-Mechanical Systems) technology, which is suitable for this device, and conducted a demonstration experiment. The device was designed to be inserted into a tracheal tube as a stylet, with tiny airflow sensors facing in three directions attached to its tip. The device requires a bending mechanism and a feeding mechanism.
