Integrated lancing test strip with capillary transfer sheet
First Claim
1. A device for sampling a bodily fluid from an incision in tissue, comprising:
- a lancet to form the incision in the tissue;
a test strip coupled to the lancet for analyzing the bodily fluid from the incision; and
a fluid collection flag extending from the test strip for drawing the bodily fluid to the test strip, the collection flag being flexible to bend during lancing, the collection flag having a sampling end portion having a structure to minimize lateral wicking of the bodily fluid.

Abstract
An integrated bodily fluid sampling device includes a lancet, a test strip attached to the lancet, and a flexible sheet extending from the test strip. The lancet and the flexible sheet form a gap sized to draw bodily fluid onto the test strip via capillary action. Further, a sampling end portion of the flexible sheet is shaped to enhance capillary action of the sheet. In one form, a removable film covers the lancet and forms a seal with the flexible sheet such that the seal surrounds a lancet tip. In another form, an insulating layer covers a portion of the lancet to prevent electrical interference between the lancet and an electrical testing system on the test strip and ensure an accurate analysis of the bodily fluid.
