AI Technical Summary
Technical Problem
Existing anesthesia masks have problems such as gas leakage and excessive friction due to the mismatch between the examination channel and the examination tube orifice when facing examination tubes of different specifications, which cannot effectively prevent a large amount of gas from escaping.
Method used
An air cushion support mechanism is adopted, which drives the diaphragm to expand through the gas delivery channel to limit gas escape, and provides lateral support through the support mechanism to ensure that the sponge pores shrink and reduce gas leakage.
Benefits of technology
It effectively prevents gas escape, ensures stable oxygen pressure inside the anesthesia mask, and improves the safety and stability of the anesthesia process.

Abstract
本发明公开了一种用于麻醉科的吸入式麻醉设备及方法。具体地说，涉及医疗麻醉技术领域，该麻醉设备包括麻醉面罩、供氧管、检查管以及在麻醉面罩上开设的检查孔，位于检查孔内设置有供检查管穿入的导送环与辅助套环，所述辅助套环与导送环固定，其特征在于：所述辅助套环内侧布设有海绵以及位于海绵外侧的支撑机构，所述支撑机构在常态下用于将海绵撑起，以使海绵在纵向方向上位于检查管穿入路径上。当气垫受压时，气垫负责将其内部空气供至隔气槽，使隔膜向检查管外径膨胀，以通过缩小预留通道来限制气体逃逸，同时，气垫与检查管相互配合对海绵提供横向支撑，缩小压缩区海绵孔隙，从而限制气体向外逃逸，保证面罩内的给氧气。
