Painless Blood Sampling Lancet with Bundled Multiple Thin Needles

Abstract

A puncturing needle device has multiple (2 or more) thin needles which are mounted onto a body part or a syringe. The combination of thinness and multitude of needle can minimize pain while drawing or injecting sufficient amount of liquid such as blood or liquid drug. The needles can be different in their length.

DETAILED DESCRIPTION

FIG. 1 is a perspective view of a painless blood sampling lancet device with bundled multiple thin needles. In this device, 3 thin needles with the same 36 gauge but in different length (4,5,6) are mounted on a universal standard sized plastic body part (7). The size of the needles can be varied, such as 34 gauge, 35 gauge, 37 gauge, or higher gauges. The number of the needles mounted on the plastic body part can be two, or even four. The length of the needles mounted on the body part is 1 mm (4), 1.5 mm (5), and 2 mm (6) in this illustration. However, the lengths of the needles can be the same if multiple simultaneous skin punctures are desirable, but it gives no choice of a single needle puncture. The needle can be made by any materials hard enough to puncture the skin.

The plastic body part has the universal standard size with 22 mm in length and 6 mm in diameter. The size, shape and configuration of the plastic body part can be modified in order to fit the skin pricking device into which the lancet device is cocked. It can be made from any material such as plastics, or others, as long as it can be held and be cocked into the skin pricking device.

FIG. 2 is a frontal view of the lancet device. Three thin needles (4,5,6) are mounted on a body part (7).

FIG. 3 is a lateral view of the lancet device. Three thin needles with different length (4,5,6) are mounted on the body part (7).

Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, when a patient receives an injection of liquid medicine, 2 thinner hollow needles mounted on a syringe rather than 1 thicker needle can cause less pain when puncturing the skin, while delivering sufficient amount of the medicine. Thus, the scope of this invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.

OPERATION

A painless blood sampling lancet with bundled multiple thin needles can be used either manually by hand, or mechanically by a pricking device. When used manually, the plastic body part (7) is held with the fingers and the needles are poked in the skin. When used mechanically, the lancet device is cocked into a commercially available skin pricking device. By releasing the trigger of the pricking device the needles hit and puncture the skin. The desirable samples can be obtained by gently squeezing the pricked skin. The area of the skin poked can be the finger, palm, heel, foot, earlobe, or any part of the body where the blood sample can be obtained.

Claims

1. A system for obtaining a blood sample from an individual comprising: a lancet having a plurality of needles mounted onto a lancet body; anda lancing device configured to retain the lancet body of the lancet and to deliver the needles to a skin surface of the individual so as to puncture the skin surface.

2. The system of claim 1, wherein each of the plurality of needles mounted onto the lancet body has a length which is equal.

3. The system of claim 1, wherein at least one of the plurality of needles projects from the surface of the lancet body by a different distance compared to the remainder of the plurality of needles.

4. The system of claim 1, wherein each of the plurality of needles of the lancet has a diameter which is at least 34 gauge or smaller.

5. The system of claim 4, wherein each of the plurality of needles of the lancet has a diameter selected from the group consisting of 34 gauge, 35 gauge, 36 gauge, and 37 gauge.

6. The system of claim 1, wherein each of the plurality of needles of the lancet is a solid needle.

7. The system of claim 1, wherein the plurality of needles are mounted perpendicularly with respect to a surface of the lancet body.

8. The system of claim 1, wherein the lancing device comprises a depth adjustment control.

9. 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; andcollecting blood from the skin surface of the individual, thereby obtaining the blood sample.

10. The method of claim 9, 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.

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

12. The method of claim 9, wherein the lancet is delivered by a lancing device.

13. The method of claim 9, wherein the plurality of needles are solid.

14. The method of claim 9, wherein the plurality of needles are at least 34 gauge needles.

15. The method of claim 14, wherein each of the plurality of needles of the lancet has a diameter selected from the group consisting of 34 gauge, 35 gauge, 36 gauge, and 37 gauge.

16. The method of claim 9, further comprising the step of performing a blood sugar test with the blood sample.
