Abstract

An improved laryngoscope blade is described wherein the blade includes an anesthetic-containing reservoir. In a first preferred embodiment for providing an anesthetic spray at the distal end of the blade, the blade includes a conduit for providing fluid communication between the reservoir and the distal end of the blade and a fluid delivery means 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 of the blade, the blade includes a fluid conduit manifold 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 tipper surface of the blade, the blade includes a porous layer located on the upper surface of the blade, the porous layer being adapted to contain an anesthetic gel.

Claims

1. A laryngoscope blade comprising:

a blade member having proximate and distal ends, the proximate end of the blade member king adapted for attaching to one end of a handle;

a reservoir for containing a topical anesthetic, the reservoir being attached directly to the blade member;

a fluid delivery means in fluid communication with the topical anesthetic for expelling the topical anesthetic from the reservoir; and

a fluid conduit for providing fluid communication between the reservoir and the distal end of the blade member.

2. The blade of claim 1 wherein the fluid delivery means is a syringe.

3. A laryngoscope blade comprising:

a blade member having proximate and distal ends, the proximate end of the blade member being adapted for attaching to one end of a handle;

a reservoir for containing a topical anesthetic gel, the reservoir being attached to the blade member;

a fluid delivery means in fluid communication with the topical anesthetic gel for expelling the topical anesthetic gel from the reservoir; and

a fluid conduit manifold for providing fluid communication between the reservoir and an upper surface of the blade member through outlet holes in the upper surface.

4. The blade of claim 3 wherein the fluid delivery means is a syringe.
