Abstract:
The syringe with an adjustable needle shield is a reusable syringe, such as for applying anesthetic to a patient during a dental procedure, with a sliding needle shield, allowing the exposed length, or application length, of the needle to be selectively adjusted. The syringe with an adjustable needle shield includes an elongated hollow barrel having opposed open and closed ends, a medicament cartridge removably received within the elongated hollow barrel, and a hypodermic needle. A first end of a plunger rod is slidably received within the elongated hollow barrel and is adapted for selectively compressing a sliding plunger end of the medicament cartridge. A cylindrical shield is provided for selectively and adjustably covering the hypodermic needle. The elongated hollow barrel slidably engages the cylindrical shield such that the cylindrical shield adjustably covers a desired portion of the hypodermic needle.

Claim (Index 6):
A syringe with an adjustable needle shield, comprising:\n an elongated hollow barrel having opposed open and closed ends, the elongated hollow barrel having a longitudinal axis; a medicament cartridge removably received within the elongated hollow barrel; a hypodermic needle extending through the closed end of the elongated hollow barrel, the hypodermic needle having opposed first and seconds ends, the first end thereof being free and the second end thereof being positioned within the elongated hollow barrel and being adapted for piercing a seal end of the medicament cartridge; a plunger rod having opposed first and second ends, the first end thereof being slidably received within the elongated hollow barrel and being adapted for selectively compressing a sliding plunger end of the medicament cartridge, the plunger rod at least partially projecting through the open end of the elongated hollow barrel, the second end of the plunger rod being adapted for manual pushing by a user's finger; the adjustable needle shield consisting of a cylindrical tubular body having opposed first and second open ends, wherein the cylindrical tubular body has an outer peripheral surface extending continuously from the first to the second open ends, the closed end of the elongated hollow barrel being slidably received within the shield through the second open end such that the shield adjustably covers a desired portion of the hypodermic needle and the first open end being free, the shield having three axially aligned locking openings formed through the outer peripheral surface; wherein the three axially aligned locking openings comprises a proximal locking opening, a distal locking opening, and an intermediate locking opening between the proximal locking opening and the distal locking opening; further wherein the cylindrical tubular body has a first inner diameter between the second end and the proximal locking opening and a second inner diameter between the proximal locking opening and the intermediate locking opening, wherein the first inner diameter and the second inner diameter are the same; a hollow cylindrical mount having opposed first and second open ends, the first open end being free and the second open end being secured to the closed end of the elongated hollow barrel, the hypodermic needle partially extending through the hollow cylindrical mount; a single engaging member; and a single elastic element securing the single engaging member to an exterior face of the hollow cylindrical mount, wherein the engaging member is selectively and releasably received through a selected one of the three locking openings formed through the shield to releasably lock an axial position of the shield with respect to the elongated hollow barrel, wherein at a first locking position the shield covers the entirety of the hypodermic needle, at a second locking position the shield partially covers the hypodermic needle, and at a third locking position the shield is fully retracted so as to fully expose the hypodermic needle.
