A new gastric-tube for anesthesia has been manufactured by adding a bursa of the stomach bottom and a bursa for locking the stomach to the conventional gastric-tube. The clinical applications on trial show that vomiting, returning of the gastric juice, misinhalation can be prevented efficiently in the patients during the operation, thus greatly increasing the safety of operational anesthesia.
