Abstract
An anesthetic laryngoscope for manual oxygen jet-ventilation, including a handle with a handle housing having a lower end, a first oxygen supply tube, and a battery container mounted in the handle housing. A blade having an observation light and a second oxygen supply tube mounted thereon is mounted on the lower end of the handle means. The first oxygen supply tube is connected to the second oxygen supply tube, and a manual oxygen on/off valve is provided on one of the first and second oxygen supply tubes. Preferably, the manual oxygen on/off valve is a manually controlled two-position, two-way valve to enable generation of a pulsing supply of oxygen through an ejector nozzle at the end of the second oxygen supply tube.
