    • PROBLEM TO BE SOLVED: To provide a laryngeal mask which securely prevents gastric juice from entering the trachea because if gastric juice is sucked into the lung, it may cause a fatal result.SOLUTION: A device 10 for maintaining an airway in a patient includes a mask 12 having a resilient conformable circumferential portions 20, 22 that are shaped such that the mask forms a seal with the larynx when the mask is positioned in the laryngo pharynx to thereby prevent ingress of extraneous fluids into the larynx. The circumferential portions 20, 22 of the mask define at least one cavity for providing fluid communication to the esophagus when the mask is inserted into the laryngo pharynx. The device 10 includes an airway tube 14 connected to or formed with the mask for passing gas to the larynx when the mask is properly inserted into the laryngo pharynx. The airway tube 14 preferably is curved in the direction where it leaves the mask.
    • 要解决的问题:为了提供一种喉罩,其可靠地防止胃液进入气管,因为如果胃液被吸入肺部,则可能导致致命的结果。 用于在患者中维持气道的装置10包括具有弹性的适形圆周部分20,22的面罩12,其形状使得当面罩位于喉咽部时掩模与喉部形成密封 从而防止外来流体进入喉部。 掩模的圆周部分20,22限定了至少一个空腔,用于当将面罩插入喉咽部时提供与食管的流体连通。 装置10包括连接到掩模或与掩模形成的气道管14,用于当掩模适当地插入喉咽时将气体传递到喉部。 气道管14优选地在其离开掩模的方向上弯曲。 版权所有(C)2012,JPO&INPIT
