Claims20
A valve unit for a system for producing a medical preparation for parenteral nutrition, the valve unit comprising:
- a housing defining:
- a duct extending along a longitudinal access of housing;
- inlets;
- and
- an outlet configured to be in fluid communication with each of the inlets via the duct, the inlets comprising upper inlets and lower inlets;
- and
- valves within the housing, each of the valves being configured to alternately connect a respective upper inlet of the upper inlets and a respective lower inlet of the lower inlets to the duct, each of the valves defining:
- a first passage configured to fluidly connect the respective upper inlet and the duct;
- and
- a second passage configured to fluidly connect the respective lower inlet and the duct, wherein:
- the first passage and the second passage each intersect a central axis of the valve,
- the first passage slopes downwardly from the respective upper inlet to the duct when the first passage fluidly connects the respective upper inlet and the duct,
- the second passage slopes upwardly from the respective lower inlet to the duct when the second passage fluidly connects the respective lower inlet and the duct, and
- each valve is rotatable within the housing between a closed position, a first opened position, and a second opened position.
