The Snake-Bite Kit, sometimes designated Suction Kit, was a first-aid item used against snake or poison insect bites, and for wounds caused by poison arrows or other missiles. It is to be used together with a Tourniquet. The Kit was distributed among troops operating in closed and remote jungle areas.
The kit was included in Item No. 9776300 – First-Aid Jungle Kit (wood container). In some cases, it would have been used as a personal first-aid item by Aidmen and Hospital Corpsmen or by individual soldiers.

As snake venom acts rapidly, first aid was to be given quickly to prevent the poison from spreading throughout the victim’s body. A Tourniquet was usually applied and was to be placed between the trunk of the body and the bite, when a snake bite had taken place in either an arm or a leg; above the knee, in foot and leg bites; and above the elbow, in hand and arm bites. Iodine was then applied to the area around the bite. Cross incisions were subsequently made over each fang mark. Finally, suction (either by mouth or by suction cup with plunger) was applied to the wound for 20 minutes before loosening the Tourniquet. After suction, sulfanilamide was sprinkled into the incisions and a sterile dressing applied.
