An intubation device for intubating a patient includes a handle for holding the intubation device by a user, a single-use intubation blade that includes a retainer clip and a mounting lug held fixedly to the intubation blade by the retainer clip, a ratchet collar that is rotatably connected to the handle. The ratchet collar is rotatable with respect to the intubation blade in a first travel direction to mount the intubation blade to the handle and in a second travel direction to dismount the intubation blade from the handle. The intubation device also includes a disabling mechanism for preventing re-use of the intubation. The disabling mechanism includes a break-away section of the retainer clip, and gear teeth that have a first gear tooth surface. When the ratchet collar is rotated the first gear tooth surface breaks the break-away section dislocating the mounting lug.
