Abstract: An emulsion containing one or several polyunsaturated, long-chain omega-3 and/or omega-6 fatty acids or their pharmaceutically tolerable esters or salts, as well as usual adjuvants and additives, is used to produce an intravenously administered medicament for treating skin diseases, in particular inflammatory skin diseases, as well as diseases of the dermatitis or eczema group. Preferably, fatty acids containing 18-22 carbon atoms, as well as their pharmaceutically tolerable esters of salts, are used. These acids or their pharmaceutically tolerable esters or salts may be used in their pure form or as components of oils, such as fish oil, highly-purified fish oil concentrates, linseed oil, primrose oil, borage oil or soya oil. Specially preferred are the pharmaceutically tolerable esters or salts of said acids, in particular the pharmaceutically tolerable esters, especially those derived from eicosapentaenic acid.

Abstract: A method and apparatus for monitoring the operability of components in a hemodialysis apparatus during dialysis treatment. The dialyzer is isolated from the dialyzing liquid circuit for a time interval during dialysis treatment. During the isolation time interval, the dialyzing liquid circuit pressure is measured and monitored to detect deviations from a mean dialyzate operating pressure. The isolation is repeated periodically, with the time period between isolation intervals dependent upon the ultrafiltration coefficient of the dialyzer. This method may be performed automatically by a microprocessor in the hemodialysis apparatus.

Abstract: A process for the immobilization of a linear polymer, in particular a polyionenes, which is soluble in an aqueous solvent, on a chemically inert carrier material and a matrix having an antimicrobial effect are provided, which are suitable for, in particularly intracorporeally applied, medical appliances and in the form of microporous membranes as filters for water purification or, in the form of beads, as a surface disinfectant. The process is characterized in that the two terminal reactive groups of the linear polymer are reacted with an excess of an alpha, omega-bifunctional compound, the reaction product obtained is dissolved in a hydrophilic solvent and applied at least once to the carrier material and then cross-linked with a cross-linking agent dissolved in a hydrophobic solvent which is chemically inert to the cross-linking agent and the carrier material.

Abstract: A latching apparatus is provided for a bearing assembly in which at least three bearing rollers, each of which is supported in a rotating fashion on a bearing journal, are arranged rotationally symmetrical and lying in one plane and guide and support a bearing race between them. The bearing journals are arranged on a carrier device that is in turn supported in a rotating fashion on a central axle aligned with the axis of rotation of the bearing race, so that the bearing race and the carrier device can rotate at different RPMs. Such a bearing assembly on a rotating carrier is especially well-suited for a centrifuge, in which a separation chamber with a centrally secured line is to be driven in such a way that the tube does not become twisted.

Abstract: The invention concerns a bag to accommodate solid or fluid concentrate which is used to prepare dialysis fluid using a dialysis machine. The bag consists of a bag body and at least one opening, whereby the opening is sealingly surrounded by a plug component (220). In the coupled state with a second plug component (210), the plug component (220) forms a flow connection with the interior of the bag. The plug component also has coupling means (276, 278) which are suitable to be connected with a second complementary plug component (210), which is disposed on the dialysis machine. By means of the plug connector, in the coupled state, a first flow path is formed from the dialysis machine to the interior of the bag and a second flow path is formed back from the interior of the bag to the dialysis machine.

Abstract: A connector system for the connection of liquid reservoirs or containers is configured in such a way that a predetermined connection sequence must be followed. For this purpose, the system has two connecting pieces (1, 2) each of which is provided with two connectors (1A, 1B, 2A, 2B), the first connectors (1A, 2A) serving to connect containers of liquid (BI, BII). The configuration of the connectors allows the two connecting pieces to be connected together by means of a specially configured intermediate piece (3), but on the other hand does not allow connection of one of the connecting pieces with a third container. The preferred area of application of the connector system is medical technology, for example the transfer of liquids during hemofiltration.

Abstract: Process and device for the treatment of lumpy products using process media, the treatment including a predetermined sequence of process steps. A chain of treatment units is moved in a stepwise manner. The product to be treated remains within the same treatment unit for the duration of the sequence of the process steps. A supply unit supplies and removes process media in a stopping-station specific manner so that the process steps can proceed simultaneously in the treatment units.

Abstract: In a dialysis apparatus having a dialyzer and a single balance chamber, the internal volume of the balance chamber is preferably at most 2/3 of the volume of the dialysis fluid chamber within the dialyzer. As a result, during the dialysis fluid recirculation cycle, at most 2/3 of the volume of fluid within the dialysis fluid chamber will be replaced by fresh dialysis fluid. Preferably, the duration of the recirculation cycle is approximately equal to the duration of the balance chamber filling cycle.

Abstract: A dosing device for volumetric dosing of a liquid additive which is added in a certain volume ratio to a fluid, in particular withdrawn blood, flowing in a first hose line, via a second hose line feeding directly or indirectly into the first hose line. The dosing device for the volumetric dosing of an anticoagulant fluid or a sedimentation accelerator is preferably provided in a system for the collection and retransfusion of autologous blood which has a hose or tube section which extends downstream from the junction, and also a drip chamber connecting downstream from the drip tube and a light barrier, the direction of action of which is arranged transversely to the fall path of the drops. In order to avoid incorrect dosing because of changing viscosities of the liquid flowing in the first hose line, and thus of changing drop sizes, two electrically-triggerable valve means, one of which is in each case inserted into one of the two hose lines, are provided.

Abstract: A sealed, flexible plastic sheet bag for storing liquids that is penetrable by a spiked connector through a spike channel fitting. The spike channel fitting is sealed between a pair of folds on one side of the bag so that the inside port of the channel is adjacent to the folded plastic sheet. The spike is inserted through the channel of the spike channel fitting and punctures the plastic sheet to tap the bag to remove the liquid. Leakage is prevented by both the seal between the plastic sheet and the spike and the seal between the bag and the spike channel fitting.
