Cuff pressure measurement device for a tracheal tube

摘要

According to various embodiments, methods and systems for determining pressure in an inflatable cuff of a tracheal tube may employ pressure transducers associated with a cuff inflation line or a pilot balloon assembly. The pressure transducers may be implemented to provide continuous or intermittent cuff pressure. Also provided are tracheal tubes with adapters or other devices that incorporate pressure transducers. The tracheal tubes may facilitate wireless cuff pressure monitoring.

主权项

1. A tracheal tube comprising:
a conduit configured to be inserted into a trachea of a subject; an inflatable cuff disposed on the conduit and configured to contact the trachea of the subject; an inflation line in fluid communication with the inflatable cuff comprising an exterior portion extending away from a wall of the conduit and a distal opening disposed in an interior space of the inflatable cuff; a pilot balloon associated with a proximal end of the inflation line on the exterior portion; an adapter positioned on the exterior portion of the inflation line and distally to the pilot balloon, wherein the adapter couples two sections of the inflation line in fluid communication with one another; and a pressure transducer positioned on a wall of the adapter comprising an interior surface exposed to fluid in the inflation line and an exterior surface exposed to ambient air.
