Patent ID: 8663558

Claim:
Device for analyzing a body fluid, the device comprising a test tape having a carrier tape and test fields, the test fields having test chemistry for the detection of an analyte in the body fluid, the test fields being distributed along the carrier tape and raised above the carrier tape and a container for the test tape, the container having a seal for passage of the test tape, wherein the test fields have a leading edge which runs against a sealing edge of the seal when the test field passes through the seal, wherein the leading edge of the test fields at least in parts are angled relative to a transverse direction of the tape; wherein each of the test fields has a thickness by which the test fields rise from the carrier tape; and wherein the seal has a flexible sealing area that is flexible to compensate for the thickness of the test fields by flexing to maintain a seal with the carrier tape, wherein the flexible sealing area contacts the carrier tape on a side of the carrier tape having the test fields, wherein the flexible sealing area rides up the test fields as the test fields pass through the seal to maintain the seal with the carrier tape.
