<p>An improved laryngoscope is described wherein the blade includes an anesthetic containing reservoir. In a first preferred embodiment for providing an anesthetic spray at the distal end (45) of the blade (30), the blade includes a conduit (35) for providing fluid communication between the reservoir (55) and the distal end of the blade, and a fluid delivery means (60) for expelling the anesthetic from the reservoir and for propelling it through the conduit. In a second preferred embodiment for providing an anesthetic gel to the upper surface (96) of the blade (94), the blade contains a fluid conduit manifold (85) for providing fluid communication between the reservoir and the upper surface of the blade. In an alternative preferred embodiment for providing an anesthetic gel to the upper surface (105) of the blade (110), the blade includes a porous layer (100) located on the upper surface of the blade, the porous layer being adapted to contain an anesthetic gel.</p> |
