Body fluid testing device
First Claim
1. A body fluid testing device for analyzing a body fluid, comprising:
- a test media tape adapted to collect the body fluid;
said test media tape comprising a tape and test media portions, wherein a free tape portion without test medium is located between successive test media portions;
a supply portion comprising a housing in which uncontaminated test media tape is contained, said housing further having an opening for withdrawing test media tape from the housing;
said supply portion further having a seal for closing said opening against the surrounding, wherein a free tape portion of said test media tape is located between a surface and the seal when said seal closes said opening;
wherein said seal comprises an annular gasket having a shore hardness of less than 70, said annular gasket pressing onto a wall of said housing annularly located around said opening when said seal closes said opening; and
wherein said seal has a first and a second lip of sealing material, wherein said first lip is inclined apart from said opening and said second lip is inclined towards said opening.

Abstract
Body fluid testing device for analyzing a body fluid comprises a test media tape adapted to collect the body fluid. The test media tape comprises a tape and test media portions. A free tape portion without test medium is located between successive test media portions. The testing device further comprises a supply portion. The supply portion comprises a housing in which uncontaminated test media tape is contained. The housing further has an opening for withdrawing test media tape from the housing. The testing device further has a sealing means for closing the opening against the surrounding. A free tape portion of the test media tape is located between a wall of the housing and the sealing means when the sealing means closes the opening. Further aspects concern a test media cassette with sealing means and a method for providing test media while holding them sealed against humidity during onboard storage.

2. A test cassette, comprising:
-
a housing including a supply portion in which an uncontaminated section of test media tape is enclosed, the test media tape including a tape and test media portions, wherein a free portion of the tape without test medium is located between successive test media portions; the housing further having an opening for withdrawing test media tape from the housing; a deformable gasket sealing the opening of the housing, wherein the deformable gasket is in continuous sealing contact with the test media tape to limit humidity influx into the housing; a tip over which the test media tape is guided, wherein body fluid is applied to the test media portions at the tip; and wherein the successive test media portions are spaced apart from each other by a distance whereby one of the test media portions is located at the tip and the next test media portion is located inside the supply portion to allow the gasket to seal against the free portion of tape between the successive test media portions. - View Dependent Claims (3, 4, 5)
