Strap-on emergency hypodermic
If you have serious anaphylactic allergies, Epipens are indispensable and probably the greatest (and simplest) medical contraption ever. Simplicity is key for this auto-injector. Just jab yourself with a dose of epinephrine, in the thigh, through your pants. The pen has saved my life several times.
However, as cool as they are, Epipens are hard to carry — unless you have a purse. For guys, the “Leg Buddy” makes it so you don’t forget your Epipens at home. Basically an ankle holster where you can store two Epipens — out of sight but never out of mind.05/15/09
