    Abstract: Medical training model with additively manufactured, individualized vessel models (10) which can be interchangeably connected in at least one training region to the fluid system (2) of an anatomically replicated training model with the respective patient-specifically replicated lumen, wherein the fluid system (2) simulates a blood circulation replacement system, wherein a vessel model (10) reproduced with patient-specific geometry can be connected to the fluid system (2) via a hydraulic quick coupling, the hydraulic quick coupling comprises as coupling pieces a plug and a sleeve or bushing, which are each provided with an inner flow channel for sealed connection when the coupling pieces are joined together, wherein in each case one of the coupling pieces is designed as an adapter on the connection side of the vessel model (10) with a flow channel course of varying diameter which connects the lumen of the patient-specific vessel model (10) to a standardized coupling connection opening.

    Abstract: The present invention relates to a lidar measurement system for the detection of the presence and/or motion of particles and/or objects in a space region remote from the lidar measurement system and comprising an interferometer arrangement, as well as to a corresponding method using such a measurement system. The interferometer arrangement comprises a continuous wave laser source (2), a photodetector arrangement (7), and optical components which are adapted to split light (23) emitted by the continuous wave laser source (2), to guide it along a first optical path constituting a measurement branch (4) and along a second optical path, which is separate from the first optical path and constitutes a reference branch (5), and to eventually have it incident in a spatially coherently superimposed manner onto the photodetector arrangement (7). The reference branch (5) has a predetermined optical path length, and the measurement branch (4) comprises a measurement portion (16), in which the light is directed away from the measurement system towards a space region remote from the measurement system and passes through the space region and light backscattered towards the measurement system by particles present in the space region is received again at the measurement system. Further, an evaluation unit (9) is provided which is coupled to the photodetector arrangement (7) and is adapted to receive the detector signal thereof and to determine from the detector signal the presence and/or movement of particles in the remote space region. The continuous wave laser source (2) has a coherence length in the range of 0.1 to 100 m.

    Abstract: Medical training model having at least one blood vessel model (1) which in at least one practice region can be connected to an anatomically replicated substitute blood circulation system (2) and in which a real instrument (17) is used, further having an image recording device (3) for creating measured images of the at least one blood vessel model (1), and having an image processing device (11) which converts the recorded measured images into an imaging blood vessel representation and makes same displayable on a screen (12), wherein the image recording device (3) is designed as a photo-optical system (8) which records transmitted-light images (13) as measured images of the at least one blood vessel model (1) for simulation of medical activity, for which purpose the at least one blood vessel model (1) is replicated in a transparently produced solid-bdy block (4) for a contrast between transparent solid-body block (4) and non-transparent instrument (17).

    Abstract: A method for coating one or more channels of a sample using a vapor deposition includes alternatingly supplying at least two gaseous precursor to one or more channels defined in a sample through at least one feed line that is connected to a first channel end of the one or more channels. An adjustable pressure gradient is generated and conducts the at least two gaseous precursors along a first flow direction (SR1) from the at least one feed line to a first discharge line through the one or more channels. The at least two gaseous precursor and reaction products are discharged from the one or more channels through a first discharge line that is connected to a second channel end of the one or more channels of the sample. Non-reacted precursors and reaction products are discharged through a second discharge line that is connected to the first channel end.

    Abstract: A device for generating laser radiation comprises a temperature-controlled optical setup comprising an optically non-linear solid state medium arranged in a resonator and an active region. The outgoing laser radiation is generated from a pump beam introduced into the optically non-linear solid state medium. A first temperature actuator and a second temperature actuator configured to independently adjust temperature values in the active region of the optically non-linear solid state medium. The first temperature actuator is configured regulate a length of the resonator by setting a first temperature value within a first portion of the active region. The second temperature actuator is configured to match phases of wavelengths generated by the outgoing laser radiation and phases of wavelengths of the pump beam radiation by setting a second temperature value within a second portion of the active region.
