AI Technical Summary
Technical Problem
Existing methods for monitoring balloon pressure using balloon manometers suffer from large data errors and require a manometer. Furthermore, leakage from the reservoir poses a significant risk to patients, impacting monitoring accuracy.
Method used
The reservoir is placed outside the airbag, and pressure changes in the airbag are monitored using a pressure indicator bladder and a reservoir bag. The pressure changes are displayed by the indicator liquid, which avoids leakage from the reservoir and improves the safety and accuracy of monitoring.
Benefits of technology
It enables safe and intuitive monitoring of airbag pressure, avoids the risk of reservoir leakage, and improves the accuracy and convenience of monitoring.

Abstract
The utility model relates to a tracheal catheter capable of monitoring air bag pressure, which comprises an air guide tube, an air bag sleeved outside the air guide tube, an inflation tube used for inflating and deflating the air bag and a pressure measuring device capable of monitoring the air bag pressure, and the pressure measuring device comprises a pressure indicating bag arranged outside the air bag and a liquid storage bag sleeved outside the pressure indicating bag. The pressure indication bag is communicated with the air bag through an inflation tube, and indication liquid used for displaying expansion and contraction changes of the pressure indication bag is arranged in the liquid storage bag. After the technical scheme is adopted, the liquid storage bag is arranged outside the air bag, the liquid storage bag is located outside the human body during use, safety is higher, risks caused by accidental leakage are avoided, the pressure indicating bag and the liquid storage bag are used for monitoring the pressure change of the air bag, simplicity and intuition are achieved, and even if the pressure change is small, the liquid storage bag can not be used. The liquid level sensor has the advantage of being convenient to monitor.
