Abstract: An injection mold that has an injector mold plate with a first injector mold plate face and an opposite second injector mold plate face, an ejector mold plate having a first ejector mold plate face and an opposite second ejector mold plate face, with the first injector mold plate face faces the first ejector mold plate face, at least one tempering medium channel connecting a tempering medium inlet of the injection mold to a tempering medium outlet of the injection mold, wherein the at least one tempering medium channel traverses an area of at least one of the second injector mold plate face and/or the second ejector mold plate face and defines a free opening in the respective mold plate face along at least a length of the at least one tempering medium channel.

Abstract: An injection molding method that includes: (a) fitting an injection molding machine with an injection mold defining one or more molding cavities, with at least one mold plate provided with one or more channels for circulation of a tempering medium, (b) providing a feed of plastic material, (c) heating the molding cavities by circulating through the channels a first tempering medium, (d) injecting plastic material into the closed heated mold to fill the molding cavities, (e) cooling the molding cavities of the filled closed injection mold until at least partly solidifying the molded plastic parts by circulating through the channels a second tempering medium, (f) opening the injection mold by parting the injector plate from the ejector plate, (g) ejecting the at least partly solidified molded plastic parts by actuation of ejector pins of the ejector plate, and (h) repeating the cycle of steps (c)-(g).

Abstract: According to the invention, a fluid exchange catheter is provided, which catheter has a proximal end and a distal end, and comprises an obligatory lumen having a proximal end and a distal end, the distal end of the obligatory lumen having a closed shape, wherein a lumen wall of the obligatory lumen forms a distal wall portion at the distal end of the obligatory lumen, the distal wall portion comprising at least one lumen opening in the lumen wall. Furthermore, the catheter comprises at least one additional lumen having a proximal end and a distal end, the distal end being arranged inside the obligatory lumen remote from the distal end of the obligatory lumen such that fluid exiting the at least one additional lumen flows inside the distal end of the obligatory lumen.

Abstract: A molding arrangement serves for molding articles at each stroke of an injection-molding machine in which an injection mold is mounted. The articles are composed of components made of different materials in cavities formed in the injection mold, with each cavities corresponding to the shape of a component whereby identical cavities are separated by angular distances and placed at equal distances from a central axis of the injection mold and parts of the cavities are formed in a separately movable section of the movable mold half. The injection molding arrangement includes an operation part for displacing the section to-and-fro between closed and open positions of the injection mold and in open positions to turn the section about the central axis angles corresponding to the angles between the cavities to form whole cavities in the injection mold in closed position.

Abstract: An infusion set for administering an infusion fluid to a patient. The infusion set includes a fluid container for the infusion fluid, an injection needle for injecting the infusion fluid into the patient's body, a flow regulator having a housing with an inlet, which communicates with the fluid container, and an outlet, which communicates with the injection needle via a fluid duct, at least one fluid chamber in the housing, at least one floater placed in the at least one fluid chamber. Moreover the infusion set comprises an inlet throttle and/or closure valve that includes a valve seat formed on the housing at the inlet and a corresponding inlet valve body connected with the floater at an axial distance from the at least one floater by at least one connector, an air gap formed between the inlet valve body and the floater, and at least one opening in the at least one connector for allowing fluid communication between the inlet throttle and/or closure valve and the housing.
