An auxiliary device for placing a larynx cover for anesthetization, it comprises a handle, a fixing sleeve, a pushing rod and a soft sleeve. The pushing rod is a flexible and elongate metallic rod, has on an end thereof the soft sleeve, and has on its front end a forked opening and on its bottom a bottom poker; the other end of the pushing rod has a turning portion. When the handle are connected with the pushing rod, the flexible pushing rod is extended into an air inlet pipe of the larynx cover to abut against the bottom of the larynx cover and push it forwardly by means of the bottom poker, so that the forked opening of the soft sleeve abuts on a protrusion on an annular rubber pipe in the larynx cover. The handle and the air inlet pipe are firmly combined by the fixing sleeve, the larynx cover will not be departed from the auxiliary device; and the larynx cover can be in an arciform shape without an opening, it can fit the curvature of the throat and will not poke the root of a tong of a patient. Just remove the fixing sleeve after positioning; the pushing rod can be drawn out in favor of working of a physician or a nurse.
