A laryngeal-mask construction comprises a tube body passing through an external expanding portion at its one end, wherein said external expanding portion is triangularly shaped and configured with indentations at its both front sides and a stud on its front end, the said tube body extends and ends with a circular plate outlet; a hollow annular resilient support, which is also supported by a horse-shoe shape fenestrated plate bridging between the said hollow annular resilient support and the groove in the extending tube is defined to surround said external expanding portion; a pliant elastomeric beret, being sticky and tensile is used for enclosing said external expanding portion and said hollow annular resilient support, after inserting into the oral cavity of a patient, the device outlet is adapted to place closer to the larynx of the patient for achieving an effective seal and lessening the risk of aspiration. |
