Abstract:

An intradermal injection device, comprised of a fine gauge injection needle and hub, is enveloped by an attached flexible tear-drop shaped bulb containing a reservoir, and which is itself attached to an integral sliding needle guard. The device contains a prepackaged dose of medication to be administered, which is sealed into the hub and bulb reservoir. Using the hub as a convenient handle, the needle is injected into the skin and the medication is discharged by squeezing the bulb between the thumb and forefinger; afterward the sliding needle guard is deployed by the same squeezing action. A hypodermic injection device, longer needle variation, is accomplished by a modification in the form of an extension to the bulb of a sleeve folding or invaginating over itself, allowing the integral sliding needle guard, when deployed, to extend over the longer needle.
