The Sawyer Extractor Vacuum Pump was designed specifically to provide the most powerful suction available for the safe extraction of venoms and poisons from the bites of snakes, bees, scorpions, stingrays, mosquitoes, and other poisonous critters. Its double-chamber pump action is so powerful, you won't need the dangerous scalpel blades or knives associated with less effective bite kits. Just select 1 of the 4 plastic cups that best covers the bitten area, attach it to the pump, and then push the plunger with your thumb to quickly and effectively remove venoms and poisons from below your skin.Manufacturer model #: B-6.
