Description

一种用于无痛胃镜的新型口咽通气道A novel oropharyngeal airway for painless gastroscopy

技术领域technical field

本实用新型涉及医疗器械技术领域,尤其涉及一种用于无痛胃镜的新型口咽通气道。The utility model relates to the technical field of medical devices, in particular to a novel oropharyngeal airway used for painless gastroscopes.

背景技术Background technique

预防低氧血症是安全实施无痛胃镜的关键,国际胃肠镜指南建议在镇静或麻醉下,补充氧气可降低胃肠镜检查时低氧血症的发生率。目前,无痛胃镜患者氧供主要通过鼻导管给氧,但这种供氧方式术中发生低氧血症的几率较高。与鼻导管给氧相比,面罩给氧可显著提高无痛胃镜患者术中氧饱和度,但这种给氧方式常会影响术者操作。各种形式的鼻咽通气装置被报道用于无痛胃镜患者,与鼻导管吸氧相比对提高机体的氧合指数均表现出较强的优势,但鼻咽通气装置具有鼻黏膜损伤、鼻出血等风险,有鼻腔畸形、鼻腔损伤的患者无法使用,且尚未有报道鼻咽通气道装置是否适用于OSAS患者的无痛胃镜检查。近期有种改良的LAM喉罩式通气装置被报道用于无痛胃镜患者,结果显示其可显著增加术中氧饱合度,提高胃镜置入率,但该装置造价昂贵且咽喉刺激较大,限制了临床推广应用。以上研究提示,喉罩和鼻咽通气装置可大大降低无痛胃镜患者,特别是肥胖和OSAS患者镇静和麻醉药物给予后导致的舌根和咽部软组织塌陷引起的低氧血症。但这些通气装置仍存在着各种并发症和经济实用性问题,因此无痛胃镜患者通气装置仍存在着改进空间。Prevention of hypoxemia is the key to the safe implementation of painless gastroscopy. International guidelines for gastroenteroscopy recommend that supplemental oxygen can reduce the incidence of hypoxemia during gastroenteroscopy under sedation or anesthesia. At present, oxygen supply for patients with painless gastroscopy is mainly through nasal cannula, but this method of oxygen supply has a higher chance of hypoxemia during surgery. Compared with nasal cannula oxygen, mask oxygen can significantly improve the intraoperative oxygen saturation in patients with painless gastroscopy, but this method of oxygen supply often affects the operator's operation. Various forms of nasopharyngeal ventilation devices have been reported to be used in patients with painless gastroscopy. Compared with nasal cannula oxygen inhalation, they all show strong advantages in improving the oxygenation index of the body. However, nasopharyngeal ventilation devices have nasal mucosal damage, nasal Patients with nasal deformity and nasal injury cannot use it, and it has not been reported whether the nasopharyngeal airway device is suitable for painless gastroscopy in patients with OSAS. Recently, an improved LAM laryngeal mask ventilation device has been reported to be used in patients with painless gastroscopy. The results show that it can significantly increase the intraoperative oxygen saturation and increase the rate of gastroscope insertion. clinical application. The above studies suggest that the laryngeal mask and nasopharyngeal ventilation device can greatly reduce the hypoxemia caused by the collapse of the base of the tongue and soft tissue of the pharynx after the administration of sedative and anesthetic drugs in patients with painless gastroscopy, especially obese and OSAS patients. However, these ventilation devices still have various complications and problems of economical practicability, so there is still room for improvement in the ventilation devices for patients with painless gastroscopy.
