Device and method for alternating measurement of chest pressure and esophageal secretion sealing

The present invention describes a device and method for alternately measuring esophageal or thoracic pressure and for sealing the gastric pharynx or trachea, in which a balloon assembly of a tube or catheter placed in the trachea or esophagus is switched between two filled or functional states, wherein the filling state of the balloon assembly in the measurement mode adopts a relaxed volume definition value with a constant volume during the measurement, and the filling state of the balloon in the functional mode of sealing the esophagus or trachea maintains a constant sealing pressure preset by a user. An adjusting device which is connected to the tube or catheter unit ensures that the filling medium is quickly moved into and out of the tube or catheter balloon in a sealed state of the esophagus or trachea, in which a target pressure for sealing the trachea or esophagus is continuously maintained, respiratory mechanics-related pressure fluctuations in the balloon are compensated by continuously, compensatingl
