摘要:
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.

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. The selected network master module in turn monitors the network bus for objects indicative of another medical device which has a higher priority, while other connected master network capable medical devices continue to monitor the network bus to detect whether the current master is de-activated or fails to operate as master. The extended network module thus automatically enables another network master capable device to take over control over the network bus.

The invention relates to a flame-retardant polyamide molding composition based on semicrystalline polyamides. This polyamide molding composition is based on (A) from 30 to 92% by weight of at least one aliphatic or semiaromatic, semicrystalline polyamide with melting point (Tm) in the range from 240° C. to 340° C.; (B) from 0 to 50% by weight of at least one filler and reinforcing agent; (C) from 8 to 18% by weight of at least one halogen-free flame retardant; (D) from 0 to 2.0% by weight of at least one barium carboxylate; (E) from 0 to 5% by weight of at least one additive; wherein the percentages by weight of components (A) to (E) give a total of 100%, and with the proviso that if the proportion of component (D) is in the range from 0 to 0.1% by weight the halogen-free flame retardant of component (C) is based on a barium phosphinate. The invention further relates to the use of barium carboxylate in a polyamide molding composition using a halogen-free flame retardant for inhibiting corrosive action during processing. The molding compositions comply with fire-protection class UL 94 V-0, and have no, or only slight, corrosive action with respect to the machine components used in thermoplastic processing, and exhibit good mechanical properties. They are suitable for producing, in particular, thin-walled moldings for the electrical and electronics industry, examples being housings, housing components, and connectors.
摘要:
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.
