    Abstract: A roller pump for medical technology, in particular for pumping blood in extracorporeal circulations. The roller pump has a stator (1) with a cylindrical hollow space (2), the wall structure of which is formed as a support wall (3) for a pump tube (5) led along this wall about the central longitudinal axis of the hollow space. A pump rotor is rotatably arranged about its central longitudinal axis (4) in the pump stator, the rotor having rollers (8) which are rotatably supported on roller supports (7) and roll along the tube upon rotation of the rotor and compress the tube. The support wall (3) of the pump stator has an opening (6) with an inlet region (10) and an outlet region (12) for the tube (5) and, in these regions, this support wall deviates from the circular path of motion of the pump rollers (8) at a differing curvature along the direction as this path of motion. The support wall (3) has a continuously increasing radius of curvature in the inlet region (10) in the direction of motion of the pump rollers (8) and a continuously decreasing radius of curvature in the outlet region (12) in the direction of motion of the rollers.

    Abstract: A detachable connection between a light-guide fiber and a laser suited particularly for medical purposes comprises two coupling elements. In the light exit opening of the first coupling element an optical coupling system is arranged which is connected to the former and can be adjusted parallel and/or perpendicularly to the optical axis. The first coupling element comprises a device for generating an axial force on the second coupling element. Between the first and second coupling elements, contact surfaces with high thermal conductvity are provided, by means of which heat is transferred in the coupled condition from the second coupling element to the first coupling element.

    Abstract: For operating a laser at different wavelengths, at least one of the two mirrors of the oscillator is subdivided into two or more regions with different spectral reflectivity, where each region reflects only one of the emission wavelengths of the laser medium and is largely permeable for the remaining emission wavelengths. Each such region can be inserted separately into the ray path of the laser.

    Abstract: A circuit for widening the stereobase in the reproduction of stereophonic sound signals contains one amplifier (10, 34) each for the stereo signals assigned to the right-hand and left-hand channel. Each amplifier (10, 34) comprises a non-inverting input (16, 36) for the corresponding stereo signal and an inverting input (18, 42) for an output signal fed back via a first resistor (R1, R5) from the amplifier output (20, 40). An ON/OFF connection is provided between the inverting inputs (18, 42) of both amplifiers (10, 34). The connection between the inverting inputs (18, 42) of the two amplifiers (10, 34) is formed by two amplifiers (48, 50) circuited in antiparallel as voltage followers and a second resistor (R8, R9) connected in series with the output of each amplifier (48, 50). The amplifiers (48, 50) circuited as voltage followers comprise a blocking input (64, 66) by which the amplifiers can be switched to an inactive state on application of a blocking signal in which they communicate no signal to their output.

    Abstract: The invention relates to an apparatus for measuring physiological parameters of blood conveyed within an extracorporeal circulatory system. Two light sources (1a, 1b) emit light of varying wavelength into a spherical cavity (3) that comprises a reflective inner surface (3a). Light sensor means (2) receives part of the light propagating within the cavity (3). A tube portion of the extracorporeal circulation can be inserted into a second cavity (4) such that the light (La, Lb) emitted by the light sources encounters the boundary surface between the blood and an inner wall of the tube. The light returns to the cavity (3) at least to an extent by means of reflection and/or transmission.
