Abstract

This is a Local Anesthesia Injection Cone. It is made of a very simple cone shaped piece of clear plastic with a flange on the tip of the cone where a Luer lock syringe can attach. There are a multiple tiny hypodermic needles protruding from the base of the cone. The number of needles would be directly proportional to the diameter of the device. It would be available in many sizes identified by the diameter of the base of the cone.

Claims

1. A device for local anesthesia injection comprising:

a cone having a distal end and a proximal end;

a base positioned on the distal end;

a chamber positioned on the proximal end;

said cone further comprising a flange with an opening peripherally connected to said chamber with a delivery device containing an anesthetic attached on top of said flange;

the cone further comprising a plurality of conduits that extend from said chamber to a plurality of needles with each said conduit connected to a single needle wherein said needles are circumferentially distributed evenly around a lower surface of the base and protrude from the base;

the cone further comprising a compressed rubber foam having a round or oblong shape attached to said base wherein said needles are buried in said foam and the length of the needle is dependent on the compressibility factor of the foam and wherein the foam contains a skin markable dye for placing a temporary ring stamp on the skin, demarcating the area of said anesthetic delivery.

2. A device according to claim 1 further comprising wherein said delivery device is a luer lock syringe said delivery device be a Luer lock syringe.

3. A device according to claim 1 further comprising wherein said delivery device is a self contained means attached to said chamber said delivery device being self contained means attached to said chamber.

4. A device according to claim 3 further comprising said self contained means is an Ampule.

5. A device for local anesthesia injection comprising:

a cone having a distal end and a proximal end;

a base positioned on the distal end;

a chamber positioned on the proximal end;

said cone further comprising a flange with an opening peripherally connected to said chamber with a delivery device containing an anesthetic attached on top of said flange;

the cone further comprising a plurality of conduits that extend from said chamber and connects to a ring shaped manifold chamber that connects to a plurality of needles wherein said needles are circumferentially distributed evenly around a lower surface of the base and protrude from the base;

the cone further comprising a compressed rubber foam having a round or oblong shape attached to said base where said needles are buried in said foam and the length of the needle is dependent on the compressibility factor of the foam and wherein the foam contains a skin markable dye for placing a temporary ring stamp on the skin, demarcating the area of said anesthetic delivery.

6. A device according to claim 5 further comprising wherein said delivery device is a luer lock syringe said delivery device be a Luer lock syringe.

7. A device according to claim 5 further comprising wherein said delivery device is a self contained means attached to said chamber said delivery device being self contained means attached to said chamber.

8. A device according to claim 7 further comprising having said self contained means is an Ampule.
