TRACHEAL TUBE CUFF PRESSURE INDICATOR.

摘要

A pressure indicator for cuffed tracheal tubes is provided. This indicator uses an indicator balloon (42) on the proximal end of the inflation lumen and in fluid communication with the tracheal tube cuff. As the pressure in the cuff changes, the balloon will inflate and deflate. An indicator needle (44) rests on the balloon and moves in response to the inflation and deflation of the balloon, thus showing the state of inflation of the cuff.
