摘要:
An embodiment of the present invention relates to a device, which can be implanted into a patient, for an in vivo measurement. In an embodiment, the device includes a catheter for guiding a sample of the patient town analysis unit in the device. A measurement result is determined in the analysis unit by analyzing the sample with the aid of a reagent. In an embodiment, the device furthermore includes an interchange chamber, with the aid of which the reagent can be removed from the device or can be inserted into the device. The interchange chamber has a connector allowing removal or insertion of the reagent while the device is implanted.

A tip of an elongate device is navigated into a particular tissue volume in order to examine the particular tissue volume in a body and part of the tissue volume is analyzed in real-time by way of a biosensor. In at least one embodiment, in the process, either the biosensor can be arranged on the tip of the device or the device includes a catheter, by which a substance to be analyzed is transported out of the tissue volume from the tip to the biosensor arranged at the proximal end of the catheter.

An in vitro method is for diagnosing a tumor disease in a patient. In at least one embodiment, the method includes: (i) determining an IVD marker or an IVD marker panel in at least one biological sample of a patient, wherein the IVD marker has a high sensitivity to the tumor disease, (ii) determining the proportion of patients tested positive due to an adapted reference range of the IVD marker/IVD marker panel, wherein the reference range was adapted such that the number of individuals with false negative tests, the number of individuals with false positive tests and the number of individuals ultimately needing to be subjected to imaging diagnostics to clarify false negative and false positive results are balanced in respect of one another such that tumor screening can be carried out, possibly: (iii) deciding to carry out an imaging method specific to the respective tumor disease for clarifying possible false negative and/or false positive IVD results, or (iv) repeating stages (i) and (ii) after a defined time interval, or (v) carrying out an imaging method for imaging the tumor.

A method is disclosed for imaging a tumor tissue, wherein in at least one embodiment a) the tumor tissue is contacted with a monoclonal antibody, an antigen-binding fragment thereof, a recombinant binding protein, an aptamer, or other molecule, each of which recognizes and binds at least one neoepitope which has been generated by proteolytic cleavage of proteins surrounding the tumor tissue by tumor-specific proteases, and b) the complexes formed from neoepitope and monoclonal antibody, antigen-binding fragment thereof, recombinant binding protein, aptamer, or other molecule are depicted with an imaging method, and also to neoepitopes generated by proteolytic cleavage of surrounding proteins by tumor-specific proteases, and also proteins or peptides for generating neoepitopes by tumor-specific proteases.
摘要:
The invention relates to methods for determining the activity of a proteolytic coagulation factor of the blood coagulation cascade in a body fluid such as whole blood or plasma. A combination is provided in a reaction mixture. The combination comprises the sample and an activation agent for activating a proteolytic coagulation factor of the blood coagulation cascade or for activating the blood coagulation cascade. The effect of the activating on a reagent system comprising a cleavable moiety is evaluated. The cleavable moiety is or becomes bound to a chemiluminescent agent or a sensitizer agent or both. The chemiluminescent agent and the sensitizer agent are related in that, when in close proximity, energization of the sensitizer agent results in energization of the chemiluminescent agent. The effect of the activating is related to the activity of a proteolytic coagulation factor of the blood coagulation cascade wherein the effect is the extent of cleavage of the cleavable moiety.

摘要:
A motor which includes two drive elements, especially piezoelectric bending actuators, having effective directions that are perpendicular to each other. These actuators act upon a drive ring to thereby rotate a shaft. Diagonally opposite securing elements are provided on the drive ring and are used to flexibly suspend the drive ring via respective articulated corner elements on respective fixing elements that are diagonally opposite the respective securing elements. The drive according to the invention is compact, having actuators that are non-radially hinged to the drive ring.

A dosing device comprises a housing (1) provided with an actuator, a dosing opening (8), a guiding shaft (6) which surrounds part of the valve needle (7) and forms a valve chamber (10) with the same, and a fluid chamber module (4) which is welded to the housing (1) in the form of a duct for guiding the valve needle (7) into the housing (9). The fluid chamber module (4) and the housing (1) are assembled along a separation surface (13) which is subjected to pressure by the dosing liquid and is formed almost only by axial cylinder wall surface parts (13) in order to reduce the pressure load on the weld seam (13).
