Abstract

A lancet removal tool 26 comprises an elongate hollow body 28 having an opening 32 at one end. The opening 32 is bounded by resilient fingers 36 which can flex to expand the opening 32 to engage the body 16 of the lancet 14. Withdrawal of the tool 26 after engagement with the lancet body 16 causes the lancet 14 to be removed from the lancet device. Subsequently, the lancet 14 can be moved from the opening 32 into the interior of the tool 26. The tool 26 and the removal procedure enables lancets 14 to be removed without risk of injury or infection from contact with the contaminated needle 18 of the lancet 14.

Claims

1. A lancet removal tool for removing a lancet from a lancet device, the lancet having a lancet body defining a transverse lancet body dimension of a predetermined size, the lancet removal tool comprising a hollow body including a resilient element and a removable cap at the end of the body away from the opening, the hollow body having an opening defined at least partially by the resilient element, wherein the opening is expandable against a resilient action of the resilient element from a rest condition, in which a transverse dimension of the opening is smaller than the predetermined size, to an expanded condition, in which the opening is sufficiently large to receive the lancet body, and wherein the lancet removal tool is arranged and configured to receive the entire lancet within the hollow body.

2. A lancet removal tool as claimed in claim 1, in which the resilient element comprises a finger.

3. A lancet removal tool as claimed in claim 2, in which the resilient finger is one of a plurality of fingers.

4. A lancet removal tool as claimed in claim 3, in which two of the fingers are provided, the fingers being disposed opposite each other.

5. A lancet removal tool as claimed in claim 4, in which the or each resilient element is provided with a ramp surface which faces outwardly of the body.

6. A lancet removal tool as claimed in claim 5, in which two of the fingers are provided, the fingers being disposed opposite of each other, in which the ramp surface is provided on each of the fingers.

7. A lancet removal tool as claimed in claim 6, in which the or each resilient element provided with the ramp surface is also provided with a shoulder facing inwardly of the hollow body, the ramp surface and the shoulder defining an inwardly directed projection on the respective resilient element.

8. A lancet removal tool as claimed in claim 7, in which an interior of the hollow body is sufficiently large to accommodate a plurality of lancets.

9. A lancet removal tool as claimed in claim 8, in which the hollow body is elongate, having a length sufficiently large to accommodate a plurality of lancets arranged end-to-end within the body.

10. A lancet removal tool as claimed in claim 9, in which the resilient element comprises a finger, in which the fingers are separated from adjacent wall portions of the body by slots formed in the body and extending longitudinally with respect to the body.

11. In combination, at least one lancet and the lancet removal tool in accordance with claim 1.

12. Blood sampling apparatus comprising a lancet and a lancet removal tool in accordance with claim 1.

13. A method of removing at least a first lancet from a lancet device, the first lancet including a lancet body, defining a transverse lancet body dimension of a predetermined size, the method comprising:

expanding an opening in a lancet removal tool, the lancet removal tool including a hollow body including a resilient element and a removable cap at the end of the body away from the opening, the hollow body having an opening defined at least partially by the resilient element, wherein the opening is expandable against a resilient action of the resilient element from a rest condition, in which a transverse dimension of the opening is smaller than the predetermined size, to an expanded condition, in which the opening is sufficiently large to receive the lancet body, and wherein the lancet removal tool is arranged and configured to receive the entire lancet within the hollow body;

engaging the first lancet with the lancet removal tool;

withdrawing the lancet removal tool and the engaged first lancet from the lancet device; and

receiving the entire first lancet within the hollow body.

14. The method of claim 13, further comprising:

engaging the lancet removal tool with a second lancet;

subsequently withdrawing the lancet removal tool and the engaged second lancet from the lancet device; and

receiving the entire second lancet within the hollow body without removing the first lancet from the lancet removal tool.

15. The method of claim 14, wherein after receiving the entire second lancet within the hollow body, the first and second lancets are arranged end-to-end within the body.

16. The method of claim 13, further comprising:

removing a removable cap from the lancet removal tool; and

removing the first and second lancets from the lancet removal tool.
