Multifunctional stomach tube and initialization method for pressure detection unit of stomach tube

Abstract

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.

Description

technical field [0001] The invention relates to the field of medical devices, and in particular provides an initialization method for a multifunctional gastric tube and a pressure detection unit thereof. Background technique [0002] In recent years, the incidence of gastroesophageal reflux disease (GERD) has gradually increased. It is a common and frequently-occurring disease in gastroenterology. The main symptoms are acid reflux, heartburn and retrosternal pain. Clinically, for patients with gastroesophageal reflux disease, it is necessary to monitor the pH and other physiological parameters in the esophagus for 24 hours. [0003] An esophageal monitoring catheter is used during the monitoring and diagnosis of gastroesophageal reflux disease. Esophageal manometry is an examination method for the diagnosis of gastroesophageal reflux disease. It is also used for the quantitative measurement of respiratory drive in patients with obstructive sleep apnea hypopnea syndrome and ...
