ORAL CAVITY LIQUID DELIVERY SYSTEM INCLUDING PRE-ANGLED NEEDLE GUIDANCE ASSEMBLY AND METHOD FOR USING THE SAME
First Claim
1. A pre-angled needle guidance assembly, comprising:
- a tube having a lumen running therethrough;
a distal portion;
a proximal portion; and
an angled portion;
wherein said tube is one continuous member throughout said distal and angled portions and said angled portion of pre-angled needle guidance assembly joins said distal portion of pre-angled needle guidance assembly to said proximal portion of pre-angled needle guidance assembly at an angle.

Abstract
A delivery system for dispensing sterile liquids into the oral cavity using a novel pre-angled needle guidance assembly attached to a conventional anesthetic needle and conventional anesthetic syringe loaded with a novel cartridge ampule containing a certain liquid solution. This system substantially improves the efficiency of delivering small amounts of sterile fluid to the oral cavity by hypodermic means or by irrigation means using pre-angled needle guidance assemblies to temporarily bend needles or cannulas in order to reach otherwise impossible-to-reach locations within the oral cavity while also providing the ability to dispose of used needles without re-bending and thus complying with federal OSHA, state OSHA, and state regulatory disposal regulations.

2. A pre-angled needle guidance assembly as in claim 2, wherein said proximal portion of pre-angled needle guidance assembly comprises:
- a concave surface at the proximal end;
a tube attachment means to connect said concave surface to said tube so that said concave surface is essentially seamlessly connected to said lumen in said tube; and
a needle attachment means to reversibly connect said proximal portion of pre-angled needle guidance assembly to an anesthetic needle assembly.
- a concave surface at the proximal end;

3. A pre-angled needle guidance assembly as in claim 3, wherein said proximal portion of pre-angled needle assembly further comprises:
- two ridges protruding radially outward, sized and spaced to cooperate accurately with the keyhole mounting slot on the needle docking station, thereby allowing said ridges freely pass through the wide opening of the keyhole mounting slot and create a “
slip fit”
between said ridges and both the narrow opening of the keyhole mounting slot and the thickness of said horizontal member. - View Dependent Claims (4, 5, 6, 7, 8, 9)

- loading an anesthetic cartridge ampule into a syringe;
mounting an anesthetic needle assembly onto the syringe;
removing the distal safety cap from said anesthetic needle assembly;
mounting said pre-angled needle guidance assembly onto said anesthetic needle assembly;
performing an oral cavity injection;
removing said pre-angled needle guidance assembly from the anesthetic needle assembly; and
recapping the distal needle on said anesthetic needle assembly with the distal safety cap. - View Dependent Claims (21, 22, 23, 24, 25)
