Patent number: 6267002Abstract: The invention concerns a process for affinity viscosimetry and a viscosimetric affinity sensor on the basis of sensitive liquids with analyte-dependent viscosity which are localized within a perfusable dialysis chamber and contain colloidal constituents which are cross-linked by affinity bonds. The viscosimetric affinity sensor according to this invention is characterized by the spatial or temporal separation of analyte diffusion from the measurement of the flow resistance for such sensitive liquid flowing through a capillary, needle-like body or other liquid conductor, which integrated combination of a dialysis chamber with viscosimeter enables a researcher to make measurements under lab conditions that provide spatial separation of the dialysis process from the rheological analysis, as done under test conditions where the maximum shear rate of sensitive liquid in the viscosity sensor is at least twice that shear rate of sensitive liquid experienced in the dialysis chamber.Type: GrantFiled: October 12, 1999Date of Patent: July 31, 2001Assignee: Disetronic Licensing AGInventors: Rudolf Ehwald, Karl-Ernst Ehwald, Andreas Thomas, Uwe Beyer

Patent number: 6193698Abstract: The present invention relates to a system for locking a dosing button in a device for the administration of a product to be injected in predetermined doses. This device comprises a body (1) with a housing (2) for the product, wherein a selected dose for injection is transported from said body out of a container (3) through a transport member (4). This device also comprises a drive member (5,7) for the transport member (4) as well as a dosing button (9) coupled to the drive member (5, 7) which is mounted so as to be capable of sliding within the body (1).
