ever had to inject something in a hurry… but couldn’t find that slipperly little vein? WaisMed has the answer! the bone injection gun!
the U.S. army is reportedly using this in combat situations. this great little gadget just injects straight into the bone marrow if you can’t find a vein!
*crunch*
brilliant! 
Looks like an evil water pistol… Oh well, beats tetanus, I suppose…
