Title:
GASTRIC TUBE
Document Type and Number:
WIPO Patent Application WO/2016/127860
Kind Code:
A1
Abstract:
Disclosed is a gastric tube (2) for avoiding aspiration, comprising a control circuit, an air pump, a pH value sensor (9) and the gastric tube (2) being provided with an balloon (12). The air pump is in communication with the balloon (12). The pH value sensor (9) is arranged at a position 40 cm away from an incisor in the inner wall of the gastric tube (2). The control circuit is connected to the air pump and the pH value sensor (9), respectively. The pH value in the esophagus and the pressure of the balloon (12) are monitored in real time by the pH value sensor (9) and a pressure sensor. Every occurrence of gastroesophageal reflux can be detect accurately and in advance, thereby avoiding aspiration caused by reflux and leading to the possibility of latent pneumonia. Automatic starting of the expansion of the balloon (12) is achieved by a real-time control method, which avoids esophageal mucosal injuries caused by the balloon (12) constricting the esophagus for a long time and can reduce a user's retrosternal discomfort.
