The first medical aspirator to be powered by alkaline batteries: no need for charging. Two alkaline battery power options are included. The first option: disposable alkaline battery pack that will power the unit for 3 continuous hours. When the battery pack is depleted, simply replace it with a fresh battery pack. The second option: a battery holder that houses 10 AAA batteries (not included) and will power the unit 60100 min. When the batteries in the battery holder are depleted, simply replace them with fresh ones. This device provides suction as efficient as a large aspirator and weighs only 2.6 lb, small enough to carry in a first-in" kit and taken to the patients side where it is needed. It can function as an extremely efficient handheld suction device or as a small, yet powerful and effective traditional suction pump. LED on the side monitors battery voltage of the alkaline battery pack and lights to alert the user when voltage is becoming low and should be replaced.
