A fiber optic probe protector for protecting a fiber optic probe such that sterilization of the probe after each use is not necessary. The fiber optic probe protector includes a sheath, a window and a handle. The sheath defines a tubular configuration, a first end, and a second end and the window is mounted in the first end of the sheath. The handle defines a first end, a second end, an interior cavity and a locking means. The second end of the sheath is mounted to the first end of the handle and the interior cavity of the handle and the sheath provide a passage for a fiber optic probe therethrough such that the face of the probe abuts against the window. The locking means locks the fiber optic probe in position. The fiber optic probe protector also includes a vacuum assembly which when hooked to a vacuum removes secretions or fluid from the surface to be analyzed with the probe.

A disposable laryngoscope blade connects to a handle especially to facilitate endotracheal intubation of a patient. The blade includes a base portion that attaches to the handle, and an elongated blade portion extends from a proximal end to terminate in a distal tip. The blade portion is arcuate and flattened so as to have a flat upper wall and a flat lower wall joined at lateral edges, and the lateral edges converge toward the distal tip. The blade includes a passageway therethrough so that a vacuum source may attach to a nipple near the proximal end and an inlet port is formed near the distal tip so that fluids may pass through the blade portion. The handle carries a battery power source and electrical contacts. The base portion of the blade also has contacts so that, when the blade is mounted a circuit is completed to power a light source disposed on the blade portion. The blade is preferably formed of two separate plastic pieces joined along a plane perpendicular to the flat upper and lower surfaces of the blade portion to create a housing for the light source and its electrical leads as well as the fluid flow passageway. The base portion has a breakaway latch that engages a notch in the handle so that removal of the blade from the handle breaks the latch structure thereby inhibiting reattachment to the handle.
