Abstract

A syringe guide includes: a syringe receiver including a receptacle configured to retain a syringe therein; a depth guide defining a reference surface; and a depth adjustment mechanism interconnecting the syringe receiver and the depth guide, and operable to change a distance between the receptacle and the reference surface.

Claims

1. A syringe guide comprising:

a syringe receiver including a receptacle configured to retain a syringe therein;

a depth guide defining a reference surface; and

a depth adjustment mechanism interconnecting the syringe receiver and the depth guide, and operable to change a distance between the receptacle and the reference surface.

2. The syringe guide of claim 1 wherein the depth adjustment mechanism has a first position which permits sliding movement between the syringe receiver and the depth guide, and a second position which prevents sliding movement between the syringe receiver and the depth guide.

3. The syringe guide of claim 1 further comprising a base defining a support surface coupled to the depth guide.

4. The syringe guide of claim 3 wherein the base is pivotable relative to the depth guide.

5. The syringe guide of claim 3 wherein:

the depth guide includes a spherical outer surface; and

the base includes a spherical inner surface which receives the outer surface such that the base is pivotable relative to the depth guide.

6. The syringe guide of claim 3 further comprising means for preventing relative rotation of the base and the syringe receiver.

7. The syringe guide of claim 3 wherein the base includes a plurality of feet protruding therefrom.

8. The syringe guide of claim 3 wherein the base includes a flat circular surface.

9. The syringe guide of claim 3 wherein the base includes an adhesive material attached thereto.

10. The syringe guide of claim 3 wherein the base includes at least one strap attached thereto.

11. The syringe guide of claim 3 wherein at least one of the syringe receiver, the depth guide, and the base is partially or wholly transparent to one or more wavelengths of radiation.

12. The syringe guide of claim 1 wherein at least one of the syringe receiver and the depth guide is partially or wholly transparent to one or more wavelengths of radiation.

13. The syringe guide of claim 1 wherein the depth adjustment mechanism comprises threads formed on the syringe receiver engaged with threads formed on the depth guide.

14. The syringe guide of claim 1 wherein the depth adjustment mechanism comprises mutually engaging non-cylindrical surfaces formed on the syringe receiver and the depth guide.

15. The syringe guide of claim 1 wherein the depth adjustment mechanism comprises a mutually engaged groove and key.

16. The syringe guide of claim 1 wherein the syringe receiver further comprises a receptacle configured to retain a taper-fit needle hub via friction fit in a distal passageway of the syringe receiver, such that a syringe barrel may be connected to or disconnected from the taper-fit needle hub while the needle remains in place in the syringe receiver.

17. The syringe guide of claim 16 wherein the receptacle is configured such that the needle hub is sufficiently retained such that the syringe can be replaced while a needle remains in a patient.

18. The syringe guide of claim 1 wherein the syringe receiver comprises markings which indicate the depth of the needle or position of the depth adjustment mechanism.

19. The syringe guide of claim 1 comprising material that can be sterilized.

20. The syringe guide of claim 1 comprising material that can be resterilized.

21. A method of administering a needle to a patient at a controlled depth, comprising the steps of:

inserting a syringe having a needle attached thereto into a receptacle of a syringe guide, wherein the syringe guide includes;

a syringe receiver that defines the receptacle;

a depth guide defining a reference surface; and

a depth adjustment mechanism interconnecting the syringe receiver and the depth guide;

determining a desired protrusion of the needle beyond the reference surface;

setting the desired protrusion of the needle using the depth adjustment mechanism; and

penetrating the patient'"'"'s body with the needle at a selected site, whereby penetration of the needle into the patient'"'"'s body is limited by the reference surface.

22. The method of claim 21 further comprising making additional penetrations with the needle at the selected site or at different sites in the patient.

23. The method of claim 22 further comprising adjusting the protrusion prior to making one or more of the additional penetrations.

24. The method of claim 21 further comprising injecting fluid into the patient from the syringe through the needle.

25. The method of claim 21 further comprising removing fluid from the patient through the needle into the syringe.

26. The method of claim 21 further comprising removing or replacing the syringe while the needle remains in the patient with the syringe guide in place.

27. The method of claim 21 further comprising:

removing the syringe guide, leaving the needle in place;

inserting a wire or catheter through the needle and into the patient; and

removing the syringe guide and needle.
