Abstract

A needle system comprising a lancet or syringe having multiple thin needles for accessing bodily fluids so as to inflict less pain and promote faster healing.

Claims

1. A lancet for use with a lancing device, the lancet having a plurality of needles mounted onto a lancet body, wherein the plurality of needles are mounted perpendicularly with respect to a direction in which the lancet is urged by the lancing device when the lancing device is actuated.

2. The lancet of claim 1, wherein each of the plurality of needles projects from the lancet body by an equal distance.

3. The lancet of claim 1, wherein the plurality of needles are at least 36 gauge needles.

4. A lancing system comprising the lancet of claim 1 and a lancing device capable of retaining the lancet and urging it forward in order to puncture a skin surface of a user when actuated.

5. The lancing system of claim 4, wherein one or more needles of the lancet projects from the surface of the lancet body by a different distance than one or more other needles of the lancet.

6. The lancing system of claim 5, wherein the lancing device comprises a depth adjustment control.

7. A method of obtaining a blood sample from an individual, comprising:

providing a lancet, the lancet comprising a lancet body and a plurality of needles mounted on the lancet body;

puncturing a skin surface of the individual with the plurality of needles; and

collecting blood from the skin surface of the individual, thereby obtaining the blood sample.

8. The method of claim 7, wherein at least one of the plurality of needles projects from the lancet body by a different distance compared to the remainder of the plurality of needles.

9. The method of claim 7, wherein the skin surface is located on a body part selected from the group consisting of a finger, a palm, a heel, an arm, a leg, and an earlobe.

10. The method of claim 7, wherein the lancet is delivered by a lancing device.

11. The method of claim 7, wherein the plurality of needles are solid.

12. The method of claim 7, wherein the plurality of needles are at least 34 gauge needles.

13. A needle device, comprising:

one or more needle hubs;

a plurality of needles attached to and in fluid communication with the one or more needle hubs, each of the needles being parallel to each other; and

a fluid conduit attached at a proximal end to the one or more needle hubs.

14. The needle device of claim 13, wherein the fluid conduit is a syringe.

15. The needle device of claim 14, wherein the syringe comprises a plurality of connecting tips, and wherein each of the connecting tips is connected to a needle hub.

16. The needle device of claims 13 or 14, wherein the one or more needle hubs comprise a plurality of needle seats for retaining a plurality of needles in each needle hub.

17. The needle device of claim 14, wherein the syringe comprises a plurality of chambers.

18. The needle device of claim 13, wherein the fluid conduit is a catheter.

19. The needle device of claim 18 wherein the catheter is attached at a distal end to a hemodialysis machine.

20. The needle device of claim 18, further comprising a stylet device having a plurality of stylets, wherein each of the stylets is adapted to fit within each of the plurality of needles.

21. The needle device of claim 18, wherein each of the plurality of needles comprises an opening on the side wall of the needle.
