Abstract: Rotary valves and methods of using, manufacturing, and storing the same are provided herein. The rotary valve includes a rotor and a stator, biased toward one another to form a fluid tight seal. In some implementations, the rotor comprises an integrated flow channel containing a porous solid support. Frequently, the interface between rotor and stator is made fluid-tight using a gasket. Some implementations of the rotary valve include a displaceable spacer to prevent the gasket from sealing against at least one of the rotor and stator prior to operation, wherein when the spacer is displaced, the gasket seals the rotor and stator together in a fluid-tight manner.

Abstract: The invention relates to a valve unit for a system for producing a parenteral nutrition, in which a three-way valve is used for respectively two connections to a source container. The valve unit is a component which is mounted on the system and can be removed again following use. The valve unit is in particular provided as a replaceable disposable component.

Abstract: A tube holder includes a tube clamp having a housing and a clamping mechanism. The housing has a tube entry along a major surface thereof. A first tube passageway extends from the tube entry into the housing, and a tube receiving channel is coupled to the first tube passageway. The clamping mechanism comprises a lever handle user operable to transition from a first position to a second position. A gate is coupled to the lever handle, and a tube pinch is coupled to the lever handle. When a tube is peripherally inserted into the tube receiving channel and the lever handle of the clamping mechanism is in the second position, the gate prevents the tube from exiting the housing via the first tube passageway, and the tube pinch pinches the tube so as to prevent a flow of a fluid through the tube.
