Schlauchvorrichtung mit Druckanzeige.

摘要

A monitor 10 for measuring the pressure in the cuff 2 on a tracheal tube 1 is clipped onto a coupling 7 at the end of an inflation indicator balloon 8. A silicon strain gauge pressure sensor 14 is urged resiliently against one side of the balloon, the other side of which rests on a base plate 12. The sensor 14 provides an output to a numeric display 18 representative of pressure in the balloon 8 and hence in the cuff 2.
