ABSTRACT:
This disclosure is directed to an improved laryngoscope blade sheath for use in the intubation process to maximize laryngoscope use by providing a single unit to orchestrate the laryngescope and the endotracheal tube. This invention is a sterile, disposable, generally linguiform laryngoscope blade sheath. The sheath is made mostly from a fairly rigid material. The inside of the sheath is hollow so that all the common standard laryngoscope blades can be inserted through its aperture. The width of the sheath is wider than the common blades and the shape of the sheath is curved and spoon-like so that the tongue can be lifted stably without slipping. There are orifices on the underneath surface of the sheath so that the light of the laryngoscope blade can shine through these orifices and the trachea can be visualized. The sheath also has an intubation guide groove underneath to make intubation more efficent. Because this sheath is used only once there is no danger of cross infection.
