Patent number: 8574496Abstract: 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.Type: GrantFiled: January 17, 2013Date of Patent: November 5, 2013Assignee: Roche Diagnostics Operations, Inc.Inventors: Werner Ruhl, Hugo Schrem, Volker Zimmer

Patent number: 8187537Abstract: The invention concerns a diagnostic test unit for analysing a body fluid comprising a test carrier (test tape 10; test strips 12) provided with test fields (38) for applying the body fluid and a container (14) containing the test carrier, wherein an opening (18) of the container (14) is at least in some areas bordered by a seal (16). According to the invention it is proposed that the opening (18) is screened by a closing foil (22) from the surroundings of the container (14) and that the test tape (10) or a test strip (12) to be dispensed is passed through a passage gap (20) between the closing foil (22) and the seal (16).Type: GrantFiled: October 24, 2008Date of Patent: May 29, 2012Assignee: Roche Diagnostics Operations, Inc.Inventors: Klaus-Dieter Sacherer, Wolfgang Ditscher, Ralf Steinbrück, Werner Ruhl, Klaus Schöttle
