  • Publication number: 20120245438
    Abstract: A medical system is disclosed, which can be useable in particular for monitoring and/or controlling at least one bodily function of a user. The medical system comprises a control device and at least one medical user element embodied separately from the control device. The medical user element and the control device are designed to exchange data wirelessly. The medical system is designed to enable an automatic assignment step, wherein an exchange of personal data between the medical user element and the control device is enabled by the automatic assignment step. The medical system is furthermore designed to automatically initiate the automatic assignment step by means of an assignment coupling between the medical user element and the control device. The medical system is furthermore designed to enable a separation of the assignment coupling for medical operation of the medical system after the assignment step.

  • Patent number: 8211379
    Abstract: Methods of manufacturing test strips are disclosed. Embodiments include laminating a two piece covering layer over a substrate with a series of cavities, wherein the two pieces are separated by a gap, the gap forming a vent opening for the cavities. Other embodiments include covering the sample receiving chamber with a cover thinner than the cover covering the body of the test strip, the thicker body cover absorbing more force than the chamber cover to reduce the possibility of adhesives squeezing out from under the chamber cover. The present invention also provides an advantageous method of mass-producing the inventive test strips without having to align the slot or vent opening laterally with respect to the test strips and without having to punch a vent opening. The method is also well suited to mass production by roll processing techniques.

  • Patent number: 8142721
    Abstract: A test strip with a covering layer having a novel slot. The slot divides the inventive covering layer into two parts and provides a vent opening that allows air to escape as fluid enters a cavity or sample receiving chamber formed in the test strip. In preferred embodiments, the covering layer is clear such that the user can see through it and the slot doubles as a “fill line.” The user can thus watch the fluid sample enter the test strip, progress through the capillary cavity, and then stop at the slot or fill-line. This provides positive assurance to the user that the sample size is sufficient and the test strip has been filled properly. The present invention also provides an advantageous method of mass-producing the inventive test strips without having to align the slot or vent opening laterally with respect to the test strips and without having to punch a vent opening. The method is also well suited to mass production by roll processing techniques.

  • Patent number: 8137980
    Abstract: The invention concerns a reagent system for the so-called on-board control of analytical elements, in particular test strips, containing an organic N-oxide or a nitroso compound. The invention also concerns analytical elements containing a reagent system for a detection reaction and a reagent system for an on-board control. Furthermore, the invention concerns a method for checking analytical elements in which a reagent system for an on-board control is examined optically or electrochemically with the aid of a measuring instrument for changes which could indicate a stress of the analytical element.

  • Patent number: 7892849
    Abstract: A test strip having a small sample-receiving chamber on the order of less than 1 microliter. The inventive test strip includes a reagent layer that extends across the width of the test strip and also extends to the sample-receiving end, such that the edges of the reagent layer are aligned with the side and dose receiving edges of the test strip. The hydrophilic reagent extending to the dosing edge of the strip promotes wicking of the sample into the test strip. The end and side edges of the reagent layer are preferably formed as part of a cutting process that forms individual test strips from a larger web, which results in a smooth and thin reagent layer with a uniform thickness, substantially covering the entire floor of the sample-receiving chamber. The inventive mass production process helps improve the reproducibility of the quantity, location, thickness and other properties of the reagent layer, which in turn improves the accuracy of the test result.

  • Patent number: 7638033
    Abstract: Biosensor system and method for the electrochemical determination of an concentration of an analyte in a sample. An analyte reactant is at least partially hydrated by the sample to form a reaction layer in contact with electrodes for measurement of an analyte detection current. The analyte detection current is characteristic of the analyte concentration in the sample by virtue of a reaction sequence comprising an analyte-specific reaction taking place in the reaction layer and an electrode reaction including transfer of electrons through an electrode surface. A plurality of values of a curve of the analyte detection current versus time are measured and the analyte concentration is derived therefrom by means of an evaluation algorithm.
