[ technical field ] A method for producing a semiconductor device
The invention relates to the technical field of medical instruments, in particular to a gastrointestinal endoscope bite piece with a nasopharynx air duct.
[ background ] A method for producing a semiconductor device
In the examination of painless gastrointestinal endoscopy, patients are generally required to be subjected to intravenous anesthesia, but outpatient intravenous anesthesia easily causes the throat muscles of the patients to be relaxed, and the patients often suffer from tongue tenesmus and insufficient ventilation, so that the oxygen saturation of the patients is reduced. Especially for obese patients, on one hand, the oxygen storage function of the patients is reduced due to limited ventilation in the examination, on the other hand, the obese patients are more prone to respiratory obstruction conditions such as glossoptosis, and the oxygen saturation is often obviously reduced. At present, the common mouthpiece does not have an oxygen inhalation passage and is only used for preventing a patient from biting an endoscope; painless gastrointestinal endoscope oxygen inhalation usually uses a mask or a nasal catheter to inhale oxygen, and the oxygen inhalation effect is not good due to tongue tenesmus, narrow nasal cavity and even bleeding of the nasal cavity caused by being placed into a nasopharyngeal airway, so that a high-flow asphyxia oxygenation technology cannot be fully used. No special gastrointestinal endoscope mouth gag with nasopharyngeal airway exists clinically.
