Description

Novel oropharynx air duct for painless gastroscope

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a novel oropharynx air vent for painless gastroscope.

Background

Prevention of hypoxemia is critical to the safe practice of painless gastroscopy, and international gastroenterological guidelines suggest that supplemental oxygen, under sedation or anesthesia, may reduce the incidence of hypoxemia during gastroenterological examinations. At present, oxygen supply of patients with painless gastroscopy mainly supplies oxygen through a nasal catheter, but the oxygen supply mode has higher probability of generating hypoxemia in operation. Compared with nasal catheter oxygen supply, mask oxygen supply can significantly improve oxygen saturation of patients with painless gastroscopy in operation, but the oxygen supply mode often influences operation of operators. Various forms of nasopharyngeal airway devices are reported to be used for patients with indolent gastroscopy, and have stronger advantages of improving the oxygenation index of organisms compared with nasal catheter oxygen inhalation, but the nasopharyngeal airway devices have the risks of nasal mucosa injury, nasal bleeding and the like, can not be used by patients with nasal cavity deformity and nasal cavity injury, and have no report on whether the nasopharyngeal airway devices are suitable for the indolent gastroscopy of the patients with OSAS. Recently, an improved LAM laryngeal mask type ventilation device is reported to be used for patients with painless gastroscopy, and results show that the improved LAM laryngeal mask type ventilation device can obviously increase intraoperative oxygen saturation and improve the gastroscopy rate, but the device is expensive in manufacturing cost and large in throat irritation, and clinical popularization and application are limited. The above studies suggest that laryngeal mask and nasopharyngeal airway devices can greatly reduce hypoxemia caused by collapse of the tongue base and pharyngeal soft tissue following sedation and anesthesia drug administration in painless gastroscope patients, particularly obese and OSAS patients. These ventilators still suffer from various complications and economic practicality issues, and thus there is room for improvement in painless gastroscopic patient ventilators.
