摘要： A dispensing device (1) for dispensing a fluid, preferably an injection syringe. The device comprises a main body (2) which has a longitudinal axis (A) and has a receiving space (3) for receiving the fluid, and a connection channel (4) communicates with the receiving space. The connection channel opens on a valve face (5) of the main body. The device comprises a movable flow control element (6) arranged on the main body. The flow control element has one or more flow channels (7) which open on a valve face (8) of the flow control element. The connection channel of the main body and the flow channels of the flow control element are fluidically connected to each other by relative movement of main body and flow control element. A sealing element (10) is arranged between the valve face of the main body and the valve face of the flow control element.

摘要： A primary packaging for a liquid including an at least partially collapsible container and a connector element for connection of the primary packaging to a withdrawal device. The connector element has at least one connector channel which is in fluid communication with an interior space of the container. The container is composed at least partially of a foil which is constructed from a first layer which, during intended use of the primary packaging comes into direct contact with the liquid. Both the first layer and the connector element are composed of a plastics material including at least one cyclic olefin polymer.

摘要： A device (1) for dispensing a fluid, in particular under aseptic conditions, preferably to a patient. The device comprises a conveying device (2) for conveying the fluid to a dispensing opening (3). The device (1) also comprises a coupling element (4) for coupling a syringe (5). The fluid can be conveyed from the syringe (5) to the dispensing opening (3) via the coupling element (4) and the conveying device (2) exclusively by the effect of the conveying device (2). The invention further relates to a system for dispensing a fluid under aseptic conditions, comprising such a device (1) and to a syringe (5) that can be coupled to the coupling element (4).

摘要： A device (1) for dispensing a fluid, in particular to a patient, comprising a container (15), in particular an at least partly collapsible container, with an interior (17) for receiving the fluid. The container (15) comprises a closure piece (20) which is rigidly arranged in the container (15) in particular and on which a dispensing opening (24) is formed, wherein the fluid can be dispensed out of the interior (17) through the dispensing opening. The device (1) comprises a pump device (40) driven by a pump drive (50) in order to pump the fluid out of the interior (17) of the container (15). The pump device (40) is fluidically arranged between the interior (17) and the dispensing opening (24) so that the fluid can be pumped out of the interior (17) to the dispensing opening (24) by the pump device (40).

摘要： The device (1) has a housing (2), and a flexible bag arranged in the housing and intended to receive a liquid. A dispensing device, in particular an injection syringe (5), is also arranged in the housing, so that it is removable from the housing. A transfer channel (6) serves for direct or indirect transfer of the liquid from the bag into the dispensing device. At least one pressure plate (7) is also provided, which can be pressed against the bag in order to empty the bag. The pressure plate is preferably activated via a spring mechanism (16), which serves as energy accumulator. The device, according to the invention, makes it possible, with a few manoeuvres, to prepare an injection liquid and deliver it to the injection syringe, with the substances being brought together by a largely automated procedure.

摘要： The dosing apparatus comprises a conveying device (5), which is driven by at least one conveying drive (4), for conveying fluid from the interior (3) of a container (2). The fluid by means of the conveying device (5) is conveyable from the container to a dispensing opening (6). The conveying device (5) comprises a cylinder (7) having at least one intake opening (11) and at least one outlet opening (12) on an inner cylinder wall (8), and a first piston (9) and a second piston (10). The first piston (9) and the second piston (10) are mounted within the cylinder (7) so as to be displaceable in the longitudinal direction. Furthermore, the first piston (9) and the second piston (10) between the end sides thereof and together with a portion of the inner cylinder wall (8) delimit a variable fluid volume (17).
