The Hypospray is a hand-held device used for subcutaneous and intravenous administration of carefully-controlled dosages of medication on a subject. The Hypospray injects the subject by use of a pinpoint, high-pressure, low-volume, microscopic, aerosuspension stream. It allows medication to be given through the skin or clothing without mechanical penetration. It takes one second to remove and one to replace a medicine vial. The air cartridge is good for 100 injections. 

The Hypospray has several major advantages over the syringe; since the skin is not broken by the spray, there is no contamination of the hyposprays tip during an injection. The device can therefore be used repeatedly without any need for sterilization of the tip. The hypospray is also completely painless, which has helped to make the widespread fear of injections a thing of the past.
