Description

Tracheal cannula capable of monitoring pressure

Technical Field

The utility model relates to the field of medical equipment, in particular to an endotracheal tube capable of monitoring pressure.

Background

Clinically, a patient with mechanical ventilation generally needs to inflate an endotracheal tube balloon, so as to seal an airway, fix the tube, ensure the supply of tidal volume, prevent oropharyngeal secretion from entering the lung, prevent aspiration, reduce pulmonary infection and the like. The balloon is positioned at the lower end part of the tracheal catheter, and a doctor injects a certain amount of gas into the balloon after intubation to expand the balloon to an ideal state, so that the lung is isolated from the outside air. The balloon is excessively inflated, so that excessive compression can be generated on capillary vessels in the tracheal mucosa of a human body, and the tracheal mucosa is damaged. The balloon is not expanded enough to cause gas leakage in the trachea, so that the effect of fixing the trachea cannula is not achieved, the mechanical ventilation quality is reduced, and the clinical treatment effect is affected. Therefore, it is important to maintain the balloon at a proper degree of inflation.

At present, the pressure value born by the tracheal mucosa is usually measured indirectly through detecting the internal pressure of the saccule by an external pressure detection device in clinic. However, due to the difference between individual structures, the same inflation volume can generate different compression forces on different individual tissues, so that the existing detection means cannot accurately evaluate the intracapsular pressure requirement.
