Abstract: An apparatus for homogenizing light, including a lens array (5, 7, 8) with a plurality of lenses (6, 9, 10) through which the light to be homogenized can pass. The apparatus has at least two different center-to-center distances of the lenses (6, 9, 10) of the lens array (5, 7, 8), wherein the center-to-center distances of the lenses (6, 9, 10) decrease or increase from the inside to the outside.

Abstract: A device for measuring pressure in a fluid line, with a fluid chamber, which is connected with the fluid line so as to allow flowthrough, and with a transducer, characterized in that the fluid chamber includes an opening to a branch line and in the branch line of the fluid chamber at least one end of a transmission element is inserted. The transmission element forms a power-locking connection between the fluid chamber and the transducer and the transmission element is suited for transmitting the fluid pressure to the transducer. This device proves to be especially precise and is easily sterilized.

Abstract: Apparatus for generating a homogeneous angular distribution of laser irradiation (17), the said apparatus comprising a first homogenization stage (10) with a first substrate (1), which includes an entrance face and exit face, wherein a first lens array (4) is disposed on the entrance face and/or on the exit face, through which first lens array the laser irradiation (17) to be homogenized can pass, as well as a second homogenization stage (11) with a second substrate (2), which includes an entrance face and an exit face, wherein a second lens array (5) is disposed on the entrance face and/or on the exit face, through which second lens array the laser irradiation (17) emitted from the first lens array (4) can pass, wherein the laser irradiation (17), after exiting from the second homogenization stage, has a comparably homogeneous angular distribution, wherein the second homogenization stage (11) in addition to the second substrate (2) has a third substrate (3), which includes an entrance face and an exit face,

Abstract: A network bus for interconnecting a plurality of medical devices is described in which the devices are provided with modules adapted to communicate along the bus. Some of the devices are capable of assuming control over the bus with network master modules. A self-configuring capability is provided with which several network master capable medical devices automatically determine which network master is to take over control over the network bus and each individually is capable of controlling and operating the network. Each network master capable device has an extended network management module with which automatic master selection is achieved. This is done by monitoring or observing network communications for particular objects. Once such an object has been detected, a network master capable device is automatically selected to take over control on the basis of its priority.

Abstract: A pressure container for applying pressure to a flexible bag received in it and filled with a medical fluid, in order to deliver the fluid from the flexible bag, has a housing that has an opening for introduction of the bag. Also provided are a cover for covering the opening, an aperture for leading a fluid discharge line of the bag out of the pressure container, and a closure for sealed joining of the cover and housing. In the interest of simpler design and easier handling, it is proposed that the housing be configured as an upright hollow-cylindrical body, closed at the bottom and open at the top, the cross section of which has a flattened oval shape and corresponds roughly to the cross-sectional contour of a bag; and that the two opposing large-area upright sidewalls each have, in mirror-image fashion, the shape of a segment of a cylindrical shell whose lateral ends are joined by joining segments.
