Abstract

A unique technique for maintaining the sterility and integrity of a lancet tip. One or more lancet tips are sandwiched between a first web and a second web of material to protect the sterility of the lancet tips. The first and second webs are heat fused together to form a structure that covers and encapsulates the lancet tips to protect the integrity of the lancet tips. The structure is cut to form individual protective caps to detachably cover each of the lancet tips.

Claims (43)

1. A device, comprising:

a lancet having a lancet tip configured to form an incision in skin;

a first web of a multi-layered material, wherein the multi-layered material has a heat-resistant first layer and a heat-sensitive second layer;

a second web of the multi-layered material, the second layer of the second web contacting the second layer of the first web and sandwiching the lancet tip between the first web and the second web to protect sterility of the lancet tip;

wherein the second layer of the first web and the second layer of the second web are configured to melt together to form a cap to encapsulate the lancet tip in the melted second layers of the first and second webs; and

wherein the first layer of the first web and the first layer of the second web form a protective outer surface of the cap, wherein the cap is adapted to be removed from the lancet.

2. The device of claim 1 , wherein:

the first layer includes polystyrene; and the second layer includes polyethylene.

3. The device of claim 1 , further comprising:

a plurality of the lancet tips sandwiched between the first web and the second web.

4. The device of claim 1 , further comprising:

a plurality of the lancet tips sandwiched between the first web and the second web;

a plurality of the caps configured to encapsulate said plurality of the lancet tips, wherein a single cap is associated with a single lancet tip; and

a cartridge for storing the plurality of the caps and the plurality of the lancet tips.

5. The device of claim 1 , wherein the cap cut to cover the lancet tip.

6. The device of claim 1 , further comprising:

a test strip attached to the lancet and adapted to analyze bodily fluid from the incision.

7. The device of claim 1 , further comprising:

an adhesive layer positioned between the heat-resistant first layer and the heat-sensitive second layer to hold the first and second layers together.

8. The device of claim 1 , wherein the first layers of the first and second webs are made of a transparent material and the second layers of the first and second webs are made of an opaque material.

9. The device of claim 1 , wherein at least one of the second layer of the first web and the second layer of the second web includes a plurality of ridges that are configured to melt together to encapsulate the lancet tip.

10. The device of claim 1 , wherein the second layers of the first and the second webs have a lower melting temperature point than the first layers of the first and the second webs.

11. The device of claim 1 , wherein the first layers of the first and the second webs are configured to contain the melted second layers of the first and the second webs.

12. A device, comprising:

a lancet having a lancet tip configured to form an incision in skin;

a cap including a first web and a second web of a multi-layered material, wherein the multi-layered material has a heat-resistant first layer and a heat-sensitive second layer,

the second layer of the second web configured to contact the second layer of the first web and to sandwich the lancet tip between the first web and the second web to protect sterility of the lancet tip; and

wherein the second layer of the first web and the second layer of the second web are configured to melt together to form the cap to encapsulate the lancet tip in the melted second layers, wherein the cap is adapted for removal from the lancet tip.

13. The device of claim 12 , further comprising:

a test strip attached to the lancet and adapted to analyze bodily fluid from the incision.

14. The device of claim 12 , wherein the second layers of the first and the second webs each include a plurality of ridges that are configured to melt together to encapsulate the lancet tips.

15. The device of claim 12 , wherein the first layers of the first and the second webs form a mold to contain the melted portions of the second layers of the first and the second webs.

16. A device, comprising:

a lancet having a lancet tip configured to form an incision in skin;

a cap configured to cover the lancet tip, the cap having a first web and a second web of a multi-layered material, the multi-layered material including a heat-resistant layer and a heat-sensitive layer, the heat-sensitive layer of the first web is configured to contact the heat-sensitive layer of the second web; and

the heat-sensitive layers of the first and second webs are configured to melt together to sandwich the lancet tip in the melted layers and form the cap.

17. The device of claim 16 , further comprising:

a plurality of lancet tips sandwiched between the first web and the second web.

18. The device of claim 17 , further comprising:

a plurality of caps configured to cover the plurality of lancet tips; and

a cartridge configured to store the plurality of lancets and the plurality of caps.

19. The device of claim 16 , further comprising:

a test strip attached to the lancet and adapted to analyze bodily fluid from the incision.
