The invention relates to the field of
medical instruments, and provides a multifunctional
stomach tube and an initialization method for a
pressure detection unit of the
stomach tube. The
stomach tube comprises a duct, a first channel for conveying
nutrient solution is arranged in the duct and provided with a plurality of flow injection holes led to outside, the flow injection holes are formed in the conveying direction of the
nutrient solution at intervals, an intraesophageal pH (potential of
hydrogen) value detection unit, a temperature detection unit and the
pressure detection unit are arranged outside the duct, a monitoring device comprises a main control module, an operator sets relevant parameters by the main control module, and the main control module is used for
processing, displaying and recording
data information acquired from detection units, 5cm position of upper portion of the lower
esophageal sphincter and a pH value of the inside of the stomach are detected,
crowds with aspiration risks can be rapidly identified, the temperature detection unit is additionally arranged on a nasopharyngeal area, so that clinical daily body
temperature monitoring is facilitated, infected patients are timely found, pressure variation of air bags can be monitored through the
pressure detection unit, so that intraesophageal pressure is reflected, and intrapleural pressure is further calculated.
