Abstract

The invention provides a visual intracavity pressure measuring device. The visual intracavity pressure measuring device comprises a processor, a synchronous database and an intraoral pressure measuring device, wherein synchronous intrathoracic pressure measurement data and synchronous intraoral pressure measurement data of a measured person are stored in the synchronous database; the processor is used for determining the mapping relation between the intrathoracic pressure and the intraoral pressure of the measured person according to the synchronous intrathoracic pressure measurement data and the synchronous intraoral pressure measurement data, and determining the intraoral pressure of the measured person according to the mapping relation and the real-time intraoral pressure, measured by the intraoral pressure measurement device, of the measured person within the preset time period, thus acquiring and displaying corresponding real-time intrathoracic pressure. By means of the invention, the comfort level and the measurement accuracy of the user can be improved.

Description

technical field [0001] The invention relates to the field of intrathoracic pressure measurement, in particular to a visualized intracavity pressure measurement device. Background technique [0002] For people with breathing difficulties, real-time monitoring of intrathoracic pressure is very necessary. Commonly used intrathoracic pressure measurement methods include: [0003] Direct method: The injection needle connected to the manometer is obliquely inserted into the pleural cavity, and the liquid of the manometer can directly indicate the pressure in the pleural cavity. The disadvantage of the direct method is that there is a risk of puncturing the visceral pleura and lungs, and the subject will feel uncomfortable. [0004] Indirect method: Let the subject swallow a catheter with a thin-walled balloon to the esophagus in the lower chest, and indirectly indicate the change in pleural cavity pressure by measuring the change in esophageal pressure during breathing. This is...
