ABSTRACT:
An laryngeal mask airway (LMA) insertion guide comprising a flexible, elongated and curved member having a rounded top end portion that serves as a handle, a bottom end that forms a rounded, flat and curved scoop, a curved fulcrum member that extends from the bottom proximate surface near the scoop, and a curved holder member that extends from the top distal surface. Each component of the insertion guide is fashioned to engage a respective LMA component, and the device curves to facilitate proper insertion and placement of the LMA in the larynx of the patient. In use, an anesthesiologist fits the LMA insertion guide onto the LMA and inserts them together into the larynx of patient, and uses the holder and scoop to bend the LMA while simultaneously using the fulcrum to push the LMA down into the patient's throat. The slender, curvilinear member permits removal of the LMA guide without widening the device or otherwise complicating its backward passage through the throat and mouth of the patient, making it safer for insertion therein, and more efficient for anesthesiologist use.
