ASPIVENIN® is a double acting twin chamber mini pump which creates a vacuum rather than pressure. It is light and easy to use. The level of suction can be up to 800mb, approximately 10 times that of using the mouth, and when applied directly over bites or stings the vacuum gently extracts the venom relieving the patient of the irritation. ASPIVENIN® should be used as soon as possible after a bite or sting occurs but can still be effective hours or even days later. ASPIVENIN® is easy to use with one hand and it is safe for use on children and the elderly.
