Abstract
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. The pressure transducers may be implemented to provide continuous or intermittent cuff pressure. Also provided are inflation assemblies or other devices that incorporate pressure transducers. The inflation assemblies may be coupled to the tracheal tubes via the inflation line.
Claims10
A tracheal tube system 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, wherein the inflation line comprises an exterior portion extending away from a wall of the conduit and a distal opening disposed in an interior space of the inflatable cuff;
- and
- an inflation assembly removably coupled to a proximal terminus of the exterior portion of the inflation line, the inflation assembly comprising:
- a pressure sensor in fluid communication with the inflation line;
- a lumen in selective communication with the inflation line and coupled to
- a valve configured to control passage of fluids into and out of the inflation line;
- and
- a hybrid connector disposed on a proximal terminus of the lumen and configured to carry fluid and electrical signals, wherein the valve is closed when the hybrid connector does not carry an electrical signal.
