The Hypospray is a simple and effective method of delivering substances intravenously to a patient. The device consists of a spray head, which can deliver drugs painlessly through the skin, and even through clothing. Attached to this is a swappable vial, which contains the drugs to be delivered. 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.
