Abstract
Abstract A combination handle unit and tongue depressor includes a light source and a means for attaching a light-transmissive disposable depressor member to the handle to conduct light from the source into, for example, the mouth and throat of a patient being examined. In some illustrated embodiments, the attachment means includes a peripheral groove about a portion of the handle unit into which the depressor member may be inserted. In some embodiments, the attachment means includes pins or posts provided on one of the handle unit or tongue depressor, and cooperating sockets for receiving the posts formed on the other of the handle unit or tongue depressor. The handle unit is conveniently designed and configured to remain out of the line of sight of the examining physician into the mouth, throat, or the like, of the patient being examined. To permit removal of the depressor member from the handle without the physician having to touch it, the handle is provided with a trigger for ejecting the depressor member.
