Darth Vader device
n.— «Losing weight can sometimes eliminate the condition, as can surgery on the back of the throat, but the standard treatment is to wear an “air splint,” a breathing mask that covers the nose and mouth and is known as a CPAP, for continuous positive airway pressure. The mask—some airport screeners jokingly refer to it as a DVD, for “Darth Vader Device”—is portable enough to be taken on camping trips if the pumping unit is fitted with a battery pack.» —“Apnea interferes with breathing and puts a strain on the heart” by Jack Cox Denver Post (Colorado) Apr. 8, 2007.
