  • Publication number: 20220300685
    Abstract: A process of assembling a filling system for low volume filling of a liquid into a container is disclosed. The process includes obtaining plural liquid forwarding devices configured to provide the liquid from a reservoir to the container, and simulating operation of each of the liquid forwarding devices by numerically modelling flow patterns of the liquid when being forwarded by the liquid forwarding devices, and by determining a shear stress rate for each of the liquid forwarding devices based on the modelled flow patterns. The process further includes determining an appropriateness for each of the liquid forwarding devices by comparing operation parameters of the liquid forwarding of the liquid forwarding devices, wherein the operation parameters include the determined shear stress rates, selecting the liquid forwarding device having the highest determined appropriateness, and installing the selected liquid forwarding device into the filling system.

  • Patent number: 11072446
    Abstract: A method of preparing a double chamber container is disclosed that includes filling a substance into the container, freeze-drying the substance therein, inserting a middle plunger in the container to form distal and proximal chambers, wherein the middle plunger seals the distal chamber from the proximal chamber and the freeze-dried substance is inside the distal chamber. The method includes filling a reconstitution medium in the proximal chamber, and sealing distal and proximal openings of the container. The method includes providing a holder having a seat and arranging the container in the seat in an upright position wherein a distal end side of the container extends downwardly and a proximal end side of the container extends upwardly. The container is arranged in the seat while the substance is filled, the substance is freeze-dried, the middle plunger is inserted, the reconstitution medium is filled, and the proximal opening is sealed.

  • Patent number: 10928236
    Abstract: A peristaltic dosing device for providing dosages of a fluid at a volume of less than one milliliter comprises: a flexible tube, a counter pressure element, a plurality of actors and a drive. The flexible tube is essentially straightly arranged along the counter pressure element thereby forming a longitudinal axis. The actors arranged parallel to each other along the longitudinal axis. They are moveable by the drive in relation to the flexible tube. The flexible tube is compressible between the actors and the counter pressure element by moving the actors. Each of the actors is independently and linearly moveable by the drive along an actuation axis essentially perpendicular to the longitudinal axis of the flexible tube from a home position in which the flexible tube is least compressed to an end position in which the flexible tube is compressed and sealed between the respective actor and the counter pressure element.
