Objective mesurements done in laboratories in France and the United States show that, according to cases, ASPIVENIN® eliminates a large amount of injected venom.
 

 
In the United States, experiments have be conducted on rabbits with rattlesnake venom, at Denver General Hospital's Anti-poison Center, in Colorado. They show that applying ASPIVENIN®, according to the technique of successive sequences of 3 minutes over one half hour can eliminate up to 39% of injected venom.
 
Venom from several Crotalus viridis helleri, marked at I125 was inoculated into male rabbits to simulate intoxications.
The residue of the substance located in the suction pump and on the skin surface was measured in a gamma counter then underwent isoelectric focusing and X-ray diffraction.
 
The effectiveness of the device could thus be rated by comparison of the initially inoculated radio-activity and the eliminated radio-activity.
The results indicate that it was possible to eliminate on average 27% of the venom after three minutes of aspiration and to eliminate on average 34% after 30% minutes of aspiration.
The highest rate of venom elimination after 3 minutes was 39%.
 

 
These tests carried out at the Pasteur Institute Immuno-Allergy Laboratory in 1984 showed by coned immuno-electrophoresis, that according to cases "non-negligible fractions of injected venom was aspirated, decreasing the gravity of envenomization".
 
ASPIVENIN® was applied on 5 persons having received a bee sting. The patients could verify that the pain diminished in about 15 seconds. A drop of venom at the orifice of the sting could be seen. About three minutes later the swelling decreased and the pain and discomfort disappeared.
 

 
The ASPIVENIN® pump, tested in real conditions with Pharmacists Without Borders in Ecuador's Amazon for three years, showed its usefulness with a satisfaction rate of 97% among the Shuar-Ashuar people, with giant ants, scorpions, tarantulas or even snakes...
 
ASPIVENIN® has a field-proven effectiveness but this does not exclude the recourse to medical care as quickly as possible in serious cases.
