The aim of this study was to design a novel, modified, multifunctional, and safe laryngeal mask airway (LMA). We designed an LMA with an internal catheter extending beyond the tip of the cuff. The protruding end of the internal catheter was provided with a catheter cuff, the space between the internal and external catheters was ventilatory, and the inlet ends of the 2 catheters were provided with standard connectors. We found that this design prevented reflux or aspiration of gastric content into the airway, prevented LMA dislocation, allowed ventilation through both the internal and external catheters, and allowed endoscopic examination and treatment of the gastrointestinal and respiratory tracts through both the internal and external catheters. This design overcomes the drawbacks and extends the functions of previous LMAs, offering a new approach to the development of LMAs.
本研究的目的是设计一种新型、改良、多功能且安全的喉罩气道（LMA）。我们设计了一种LMA，其内部导管延伸至套囊尖端之外。内部导管的突出端设有导管套囊，内、外导管之间的空间用于通气，两根导管的入口端均设有标准接头。我们发现，这种设计可防止胃内容物反流或误吸入气道，防止LMA移位，允许通过内、外导管进行通气，并允许通过内、外导管对胃肠道和呼吸道进行内镜检查及治疗。该设计克服了以往LMA的缺点并扩展了其功能，为LMA的发展提供了一种新方法。
