I have always had a bit of a thing for kits; fishing kits, survival kits, first-aid kits you name it. My latest find is the "Cutter Hi-Lo Suction Snakebite Kit." Although incision and suction is no longer recommended first-aid this is still an ingenious piece of kit.
FOR REFERENCE ONLY THIS IS NOT RECOMMENDED FIRST-AID
Using the kit is very simple although it does sound a little archaic. If someone gets bitten clean the provided scalpel blade and wound with the antiseptic unit and make a ¼" incision over the bite. Apply one of the suction cups on the bite and squeeze. This creates a vacuum drawing blood and hopefully venom from the wound. Then the lymph constrictor should be tied above the wound and the victim should get to the hospital immediately. It is called the Hi-Lo Suction Kit because different amounts of suction can be put onto the wound depending on which cup is used and how it is applied.
