An injection device that comprises a chamber configured for containing a substance to be injected and a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an intradermal injection site. A collar surrounds the needle, defining a collar cavity. The collar also has a peripheral forward skin-contacting surface that surrounds and is radially spaced from the needle and injection site by an area that is sufficiently large to allow a patient's skin to move into the collar cavity to properly position the needle for intradermal delivery of the substance to the injection site to allow spread of the injected substance under the skin while inhibiting or preventing backpressure within the skin from forcing the substance out through the injection site.

1. An injection device, comprising: a chamber configured for containing a substance to be injected;a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an injection site; anda collar surrounding the needle and defining a collar cavity, the collar having a peripheral forward skin-contacting surface that surrounds the needle, is discontinuous, and is radially spaced from the needle and injection site by an area having a diameter of at least about 4 mm;wherein the peripheral forward skin-contacting surface is the part of the injection device that is the most radially spaced from the injection site and contacts a skin surface that is radially spaced from the injection site when the injection device is pressed against the skin surface for an injection. 2. The injection device of claim 1, further comprising an energy source associated with the needle to assist in delivering the substance to the injection site. 3. The injection device of claim 2, wherein the energy source is configured to provide an injection assisting pressure of between about 50 and 300 psi to the substance. 4. The injection device of claim 1, wherein the peripheral forward-skin-contacting surface has only two portions. 5. The injection device of claim 1, wherein the needle has a delivery end having a position in which it is disposed within about 0.5 mm of the peripheral forward-skin-contacting surface. 6. The injection device of claim 1, wherein the needle and collar are configured for injecting the substance intradermally with the needle penetrating the patient. 7. An injection device, comprising: a chamber configured for containing a substance to be injected;a needle operatively associated with the chamber and having a length sufficient to deliver the substance to an injection site; anda collar surrounding the needle and defining a collar cavity, the collar having a peripheral forward skin-contacting surface that surrounds the needle, is discontinuous, and is radially spaced from the needle and injection site by an area having a diameter of between about 2 mm and about 10 mm;wherein the peripheral forward skin-contacting surface is the part of the injection device that is the most radially spaced from the injection site and contacts a skin surface that is radially spaced from the injection site when the injection device is pressed against the skin surface for an injection. 8. The injection device of claim 7, further comprising an energy source associated with the needle to assist in delivering the substance to the injection site. 9. The injection device of claim 8, wherein the energy source is configured to provide an injection assisting pressure of between about 50 and 300 psi to the substance. 10. The injection device of claim 7, wherein the peripheral forward-skin-contacting surface has only two portions. 11. The injection device of claim 7, wherein the needle has a delivery end having a position in which it is disposed within about 0.5 mm of the peripheral forward-skin-contacting surface. 12. The injection device of claim 7, wherein the needle and collar are configured for injecting the substance intradermally with the needle penetrating the patient.
