Abstract: An endoscopy capsule is provided for detecting a metabolic product of a bacterium located in a gastrointestinal tract, wherein the endoscopy capsule has a sensor unit with two electrodes and has a capsule shell that encloses a usable space, and wherein the electrodes are routed through the capsule shell.

Abstract: The invention relates to a sensor instrument (2) for examining the mucous membrane of the oesophagus, stomach and duodenum of a patient to see whether it is infected with bacteria. Said instrument comprises an evaluation unit (4) and a catheter probe (6) with an ammonia-sensitive sensor (8) and a catheter.

Abstract: In a method for producing a sensor instrument (2) having an ammonia-sensitive sensor (8), said sensor being designed to examine the mucous membrane of the esophagus, stomach, and duodenum of a patient for infection with bacteria, at least one electrically conductive wire (10) is embedded in a non-conductive matrix (12) and then an end of the wire (10) is exposed by way of grinding.

Abstract: A method is disclosed for determining analysis information supporting a user assessing the effect of a biological agent on the treatment of a rheumatic disease. The method includes, subsequent to starting the administration of the biological agent: recording a first morphological magnetic resonance imaging record of at least one target joint using a first magnetic resonance sequence; recording a second magnetic resonance imaging record showing the blood flow through the target joint by perfusion imaging using a second magnetic resonance sequence; determining at least a first measuring parameter related to the morphology of the joint by analysis of the first magnetic resonance imaging record and at least a second measuring parameter describing the blood flow in the target joint by analysis of the second magnetic resonance imaging record; and automatic determination of the analysis information from the first and the second measuring parameter.

Abstract: An endoscopic capsule has a biocompatible capsule housing that contains at least one sensor device for acquiring medical data. The sensor is arranged on an outer surface of the housing, and has a first electrode produced of an acid-resistant noble metal, and a second electrode produced of silver. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable is measured between the first and second electrodes when ammonia is present. The endoscopic capsule allows screening of gastric acid and the tissue of the stomach lining for Helicobacter pylori in a manner that is gentle for the patient.

Abstract: A gastroscope has an insertion tube with a distal end, at which a sensor is located. The sensor has a first electrode produced of an acid-resistant noble metal, and a second electrode produced of silver. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable is measured between the first and second electrodes, when ammonia is present. The gastroscope allows screening of gastric acid and the tissue of the stomach lining for Helicobacter pylori in a manner that is gentle for the patient.

Abstract: An endocapsule has a measurement chamber therein containing a sensor that detects at least one metabolic product of a specific bacterium in a hollow organ of a human or animal gastrointestinal tract. The endocapsule is introduced into the hollow organ wherein detection of the at least one metabolic product takes place.

Abstract: A diagnostic device as a first electrode formed by a noble metal that is not attackable by acid, and a second electrode that is formed of silver. The first and second electrodes are at least partially immersed in a nutrient solution contained in a container, into which a tissue sample can be introduced. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable between the electrodes is measured when ammonia is present. The diagnostic device allows fast screening of tissue samples for Helicobacter pylori.

Abstract: A gastroscope has an insertion tube with a working channel therein, and a sensor is guided in the working channel via a guidewire. The sensor has a first electrode produced of an acid-resistant noble metal, and a second electrode produced of silver. An electrical voltage is applied between the first and second electrodes, and a change in an electrical variable is measured between the first and second electrodes when ammonia is present. The gastroscope allows screening of gastric acid and tissue in the stomach lining for Helicobacter pylori in a manner that is gentle for the patient.
