Abstract: An endoscopy system has an endo-robot that is navigable within an anatomical lumen of a patient by interacting with a magnetic field generated by an extracorporeal magnet system. The patient lies on a patient bed that is movable in one or more directions and/or orientations, and an obstacle detects objects in the movement path of the endo-robot in the anatomical lumen and produces a signal that causes the position and/or orientation of the patient bed to be altered dependent thereon.

Abstract: A method for optimizing a gas conversion rate in a respiratory gas analyzer, more particularly for nitric oxide (NO) in the respiratory gas, and an associated device are disclosed.

Abstract: A method is proposed for determining clinical study compliance. The method includes obtaining criteria for the clinical study and accessing stored clinical data relating to the clinical study. Thereafter, the criteria and clinical data are correlated to determine a measure of compliance with the criteria of the clinical study.

Abstract: A method for studying a biological sample in a biochip (“lab-on-a-chip”) is disclosed. In at least one embodiment of the method, a biological sample is introduced into the biochip, the sample is subjected to at least one preparation step and, at the end of a measurement cycle, the concentration of a particular analyte is measured. The concentration of a marker substance, which for example is a reaction substance involved in a preparation step, is furthermore measured. A corresponding biochip is further disclosed.

Abstract: A multifunctional control valve for gas measurement instruments, e.g., for respiratory gas analysis, is disclosed. In at least one embodiment, the multifunctional control valve includes a first inlet opening, an outlet opening, a main line, and a bypass line, wherein a measurement chamber is in the main line, wherein the measurement chamber is arranged downstream of a first multiway valve which can selectively connect the main line or the bypass line with the inlet opening, and wherein the measurement chamber is arranged upstream of a second multiway valve which can selectively connect the main line or the bypass line with the outlet opening.

Abstract: A self-locking T-piece connects an attachment to a breathing gas line. The self-locking T-piece has a line section (2), a connection line (4) branching off therefrom, a movable valve body (10) with a valve disk (12), and a valve seat (14). The valve body (10) is prestressed by a spring (16) into a position to seal the connection line (4) against the line section (2), with the valve disk in the valve seat, and moves out of the sealing position when connecting the attachment to the connection line. The valve body (10) is elastically deformable such that it can be advanced through the connection line (4) and the valve seat (14), while undergoing elastic deformation, and returns to its original shape during the entry of valve disk (12) into the line section, in which it has a sufficient extension to be able to cover the valve seat for sealing.

Abstract: A breathing tube connecting device is provided for connecting a breathing tube to at least two respirators. The breathing tube connecting device includes a base body with a breathing gas through duct embodied in the base body, a jacket body, which can be meshed with the base body in a positive-locking manner and thus encloses at least a part of the base body in a coaxial manner, and a transponder. The transponder is provided between the base body and the jacket body. The breathing gas through duct and the jacket body are embodied at least partly as a coupling section for a selective connection of the breathing tube to one of the at least two respirators.

Abstract: An apparatus is disclosed for processing a sample which stores processing reagents required for processing in a dry form. The processing reagents are covered by a biologically degradable medium or embedded in said biologically degradable medium.

Abstract: The invention refers to a computer implemented method, a computer system a test machine and a computer program product for executing conditioned and qualified test. An ordering instance may order a set of tests, comprising an initial test and a set of follow-up tests, wherein the execution of each of the follow-up tests is dependent of the result of the respective predecessor test, like the initial test. The conditions for executing the follow-up tests are dynamically definable and are analyzed automatically.

Abstract: A device for releasing breathing gas establishes constant flow conditions for the breathing gas being discharged. An annular connection element (6) is provided between an outer part (2) and an inner part (4), and a discharge gap (7) is formed between the connection element (6) and the outer part (2).

Abstract: A device is for repeated semi-invasive abrasion of lesions on the walls of hollow organs, in particular blood vessels or the gastrointestinal tract of a patient. The device includes an outer stent which, fixed in position at the site of the lesions, can be clamped against the wall of the hollow organ and has recesses through which the lesions can inwardly protrude. The device further includes a cutting body which is guided within the outer stent and only negligibly narrows the internal bore of the outer stent, which cutting body has cutting edges sliding on the inner side of the outer stent and is coupled magnetically to an external magnet system via which it can turn about the stent axis and/or can move longitudinally along the stent axis.
