Breather applied to painless gastroscope diagnosis and treatment airway management

Abstract

The invention discloses a breather applied to painless gastroscope diagnosis and treatment airway management. The breather comprises a tooth pad and an air channel which are combined and is characterized in that the tooth pad comprises a tooth pad retaining plate matched with the radian of the upper and lower lips, an elliptical tube is connected to the inner side of the middle of the tooth pad retaining plate, the air channel comprises an air channel elliptical tube, the part outside the opening of the air channel elliptical tube extends to form an air channel retaining plate adaptive to thetooth pad retaining plate, the air channel retaining plate and the tooth pad retaining plate are connected through a connector, three tube cavities are arranged in the air channel elliptical tube, themiddle cavity is a gastroscope channel, and the two cavities on two sides of the gastroscope channel are respectively an aspiration channel and an oxygen supply channel. By the breather, the problemsthat airway obstruction in a traditional method causes hypoxemia, and oropharynx secretion and gastroscope's irritation to the throat cause the bucking, apnea or blood oxygen saturation lowering of patients are solved.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a ventilation device used for airway management in painless gastroscopy diagnosis and treatment operations. Background technique [0002] Due to the continuous improvement of patients' requirements for the comfort of medical diagnosis and treatment operations, painless gastroscopy diagnosis and treatment operations are becoming more and more popular. [0003] Painless gastroscopy operations are often performed under intravenous anesthesia. After the anesthesia is satisfactory, the gastroscope is inserted for diagnosis and treatment. However, after the patient is anesthetized, due to the retraction of the tongue and the obstruction of the tongue base, airway obstruction often results in hypoxemia. At the same time, the irritation of the throat by oropharyngeal secretions and gastroscopy often causes coughing and apnea in patients. Since the airway is not directly managed...

AI Technical Summary

Problems solved by technology

[0003] Painless gastroscopy operations are often performed under intravenous anesthesia. After the anesthesia is satisfactory, the gastroscope is inserted for diagnosis and treatment. However, after the patient is anesthetized, due to the retraction of the tongue and the obstruction of the base of the tongue, airway obstruction often results in hypoxemia. At the same time, oropharyngeal secretions and gastroscope irritation to the throat often cause coughing and apnea in patients. Since the airway is not directly managed, once apnea or blood oxygen saturation decreases during endoscopy, It is often necessary for the endoscopist to stop the operation, or even pull out the endoscope to perform assisted ventilation on the patient, which obviously poses a safety hazard
