Abstract
A laryngoscope is disclosed herein which includes a handle and a separate disposable blade. The disposable blade is designed for a single proper operative use, enabling greater sterility. After the single first proper operative use, and upon disengagement from the handle, certain blade components are sufficiently damaged, whereby the blade is not able to cooperatingly engage and remain retained in the handle, for a proper second operative use.
