ABSTRACT:
An illuminated tongue depressor is formed by an elongated relatively narrow body having a handle end portion containing a battery and a proximal end portion having a curvature conforming to the larynx defining a convex top surface and a concave ventral surface having a friction inducing antislip texture adjacent its proximal end. A lamp imbedded in the top surface is connected with the battery by wiring through a switch. A sanitary disposable sheath envelopes the proximal end portion of the body.
