Abstract
Abstract AN INJECTING DEVICE FOR A HYPODERMIC SYRINGE RAPIDLY PROJECTS THE SYRINGE NEEDLE THROUGH A SURFACE ENGAGING END OF A HOUSING ADAPTED TO FIT WITHIN THE HAND. AN INJECTOR BAR ACTUATES THE SYRINGE PLUNGER AFTER THE NEEDLE HAS PENETRATED THE SKIN AND TISSUES. PRIOR DISENTIZING OF THE SKIN BY DISCHARGE OF COOLANT FROM A PRESSURIZED CONTAINER IN THE HOUSING, MAY BE UTILIZED TO REDUCE PAIN AND IRRITATION. THE NEEDLE PROJECTING MECHANISM MAY ALSO BE CONDITIONED TO PRODUCE ASPIRATION FOR DETECTING WHETHER THE NEEDLE HAS PENETRATED A BLOOD VESSEL, BEFORE MEDICATION IS INJECTED BY THE PLUNGER.
