Technical Field
The utility model relates to the technical field of medical instruments, in particular to a gastroscope backflow preventing and aspiration preventing device.
Background
Painless gastroscopy is a medical examination method and also refers to the instrument used for such examination. It is inserted into the stomach by means of a slender, flexible tube, and the doctor can directly observe the lesions of the esophagus, stomach and duodenum, especially for small lesions. The gastroscopy can directly observe the real condition of the checked part, and can further definitely diagnose the pathological biopsy and cytology check of the suspicious lesion part, thereby being the first checking method of the upper digestive tract lesion. Reflux aspiration refers to the process of regurgitation of gastric contents through the throat into the lower respiratory tract, which can cause acute respiratory obstruction and aspiration pneumonia, and is a serious complication that may occur in painless gastroscopy.
At present, patients who are subjected to painless gastroscopy are usually informed of the need of forbidding to drink and fasted food in the evening before the examination, so that the occurrence rate of reflux aspiration is greatly reduced, but part of patients (such as gastroparesis and pyloric obstruction) still have larger reflux aspiration risks. And the possibility of regurgitation and aspiration of patients under special conditions (such as hematemesis, hemorrhagic shock, coma, and need of hemostasis under urgent digestive endoscopy) is extremely high after patients eat. In view of the above, a general treatment method is to perform tracheal intubation under general anesthesia. However, there is still a risk of aspiration during the tracheal intubation, and the patient needs general anesthesia and delays the treatment time, so we propose a gastroscope aspiration preventing device to solve the above problems.
