The Sawyer Extractor Mini Pump Kit extracts venom and saliva from under the skin from the bites and stings of mosquitos, bees, wasps, biting flies, no-see-ums, chiggers, sea lice, and more. First aid relief can come in 5 seconds when the irritating material is retrieved. The extractor's simple vacuum pump action and compact size makes it perfect for your car, camping first aid kit, or to carry on a hike. This kid-friendly design includes a stinger-scraper built into the handle. A reversible suction cap provides two different sized areas for suction and two different positions for suction strength. This ingeniously simple design is a pump, not a syringe, so it's easy to use with one hand. No batteries needed or complex parts, just clean and reuse the Extractor Mini Pump over and over again. The Sawyer Extractor Mini Pump is most effective at retrieving venom and saliva outside of the muscle areas of the body. Retrieving venom quickly can significantly improve treatment results by medical practitioners. Note that in muscle areas such as the calf muscle, venom quickly enters the circulatory system and an extractor pump is less effective. The Sawyer Extractor Mini Pump is for first aid only: Seek immediate medical attention if you experience an allergic reaction, severe bite, or infection. Not for use with snake bites. Since 1984, Sawyer has used technological advancements to create products that keep you outdoors — from the backcountry to the backyard.
