The invention relates to a method for determining the coagulation time of a sample fluid containing blood components by means of a resonator whose vibration parameters are measured and then used as a basis for determining the sample fluid viscosity change, which resonator has an at least partially adhesive surface contacting said sample fluid. The invention is characterized by preincubation of said surface with a preincubation fluid containing blood components, which preincubation fluid has a known way of interacting with the coagulation system, thus resulting in anchoring sites to be formed on the adhesive areas of said surface.

Blood coagulation time determination method and apparatus

The invention relates to a measuring device () comprising a resonator () having a sensitive) being inserted in the region and a base support unit () for measuring properties of a fluid, the resonator (base support unit () and contacted therein, the sensitive region remaining accessible to the fluid, and the resonator () being activatable via connection points () on the base support unit (). The invention is characterized in that the base support unit () is formed solely by a film arrangement.

Measuring device comprising a resonator having a film carrier

The invention relates to a method and a device for producing a moulded body having microstructures from moulding material. The method for producing a moulded body having microstructures on a carrier out of moulding material is effected by inputting a moulding material into a container () comprising a mould cavity (), wherein at least one micro-structured mould () is provided in the mould cavity. Furthermore, the centrifugation of a container () is carried out until the moulding material has completely entered into the structure of the mould (). Thereafter, the curing of the moulding material is carried out to form a moulded body having microstructures, which is then removed from the mould () and the container (). A container () is provided into which the mould () has been inserted, and the container () is connectable to a centrifuge wherein the container () comprises a mould cavity for receiving the moulding material wherein the mould cavity () comprises at least one micro-structured mould ().

Device and method for producing a moulded body having microstructures

The invention relates to an apparatus () for carrying out measurements of a analyte fluid having a housing (), a measurement chamber () arranged in the housing (), a resonator () and conduits () for inputting and outputting media for the measurements into/out of the measurement chamber (), wherein the resonators () delimit the measurement chamber () in areas. The invention distinguishes thereby that two resonators () are provided which delimit the measurements chamber () each.

The invention relates to a method for determining haemostasis parameters by measuring vibration parameters of a resonator having a measuring surface which contacts a platelet containing sample fluid. The invention is characterized by the analysis of the characteristic of a vibration parameter over time, based on which the platelet function will then be assessed and a distinction will be made between the presence of an adhesion disorder or that of an aggregation disorder.

Thrombocyte function determination method using a resonator

The invention relates to a measurement device with at least one resonator, comprising a measurement chamber with a fluidic input and a fluidic output wherein the measurement chamber is delimited, at its bottom surface, by a resonator, and wherein the resonator surface is configured to be electrically conducting, and the resonator surface forms the working electrode for an electrochemical measurement, and wherein electrodes are provided at the fluidic input and/or output at the transition to the measurement chamber. The invention is characterized in that the electrodes are exchangeable and allow the reception of a fluidic connection.

Measurement device with resonator

The invention relates to an apparatus comprising a measurement chamber and a resonator, which can be integrated in the measurement chamber via a quick-action closure, for the liquid sensor system and for verification and measurement of the concentration of materials, substances, particles and/or microorganisms in liquids. The invention is characterized in that the resonator is held only on its outer circumference by a thin elastomer ring, and in that at the radial distance of the external diameter of the resonator, the elastomer ring on the one hand rests on an upper sealing ring of the measurement chamber, forming a seal, and on the other hand rests on a holding ring.
