Process for manufacturing packaged lancets and device for analyzing body fluid
First Claim
Patent Images
1. A process for manufacturing packaged lancets, comprising the steps of:
- providing a metal sheet comprising a plurality of lancets which are fixed to the metal sheet via at least one predetermined breaking point whereby the lancets comprise a lancet tip and a lancet body;
positioning the metal sheet relatively to a tape comprising at least one foil for enveloping at least the lancet tip;
placing at least one lancet onto the tape and pressing the at least one lancet on the tape so that the at least one breaking point is broken and the lancet is no longer connected with the metal sheet;
and before, simultaneously, or afterwards fixing the lancet on the tape,removing the metal sheet and enveloping at least the lancet tip with the foil, whereby the foil builds a first and a second portion that overlap at least partly,and sealing the at least one foil preferably with a laser beam at least at the edges of the first and second portion of the overlapping foil.

Abstract
Disclosed is a process for manufacturing packaged lancets. The steps of the process include providing a tape comprising a plurality of lancets comprising a lancet tip and a lancet body, enveloping at least the lancet tip with at least one foil, whereby the at least one foil forms a first and a second portion that overlap at least partly, and sealing the at least one foil with a laser beam at least at the edges of the first and second portion of the overlapping foil.

2. A process for manufacturing packaged lancets, comprising the steps of:
- providing a tape comprising a plurality of lancets comprising a lancet tip and a lancet body,
enveloping at least the lancet tip with at least one foil, whereby the at least one foil builds a first and a second portion that overlap at least partly, applying a force to the foil in such a way that the foil is pressed onto the lancet by a first component of the force in a first direction and, moreover, by a second component of the force in a second direction perpendicular to the first direction so that the first and second portion of the foil overlaps and at least one portion of the foil is flattened towards the end of the lancet opposite to the lancet tip, and sealing the at least one foil preferably with a laser beam at least at the edges of the first and second portion of the overlapping foil. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A process of manufacturing a device for analyzing a component in a body fluid, comprising:
-
providing a lancet with a lancet tip and a lancet body and at least one foil, that envelopes at least the tip of the lancet whereby the at least one foil builds a first and a second portion that overlap each other at least partly, wherein the foil is sealed after enveloping at least a part of the lancet by treating at least the edges built by the two partly overlapping portions of the at least one foil preferably with a laser to keep at least the lancet tip in a hermetic surrounding; and joining the lancet with a test element comprising a body fluid application field before or after sealing the device.
