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.
Claims19
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.

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.
