A sterile airway device.  There are several types of airway devices, but I'm
guessing this refers to the simple oropharyngeal airway.  This is a set of
them in different sizes  http://www.life-assist.com/aa07.jpg  The device
fits into the mouth, maintaining an open airway.  It can only be used in a
patient who's unconscious and has no gag reflex.

"Airway" is a generic term.  It could also refer to endotracheal tubes,
laryngeal mask airways, Combitubes, or several other types of airway
devices.

It's spelled "yankauer."  A sterile device for suctioning the airway.  Photo

A soft collar that fits around the neck in order to hold the neck in a

These are used to maintain neck normal position in patients with spinal
injuries, patients who are intubated, or any other time movement of the head
and neck needs to be minimized.

I don't know what "lumbortod" means (I think you may have it spelled wrong),
but a corset is a device that fits around the lower abdomen and provides
support to the spine
