Valves
There are eight valves located on the MCS+ top deck which automatically control
the flow of fluids through the disposable set tubing. The valves are color-coded
and correspond with specific sections of disposable set tubing. Each valve also
contains a light to indicate an open (lit) or closed (not lit) state. The MCS+ safety
system will control the valves during the power-up self-diagnostic tests. Once the
operator has selected a collection protocol, the appropriate valves will open
automatically and be lit, in preparation for loading the disposable tubing.
Note: The function of each valve will depend on the selected MCS+ protocol,
however the red-coded valve (N° 3) is consistently used as the “donor“ valve.
During the different modes of the selected MCS+ protocol, the valves will operate
automatically, opening and closing depending on the passage of fluids. However,
the valves can be opened manually if the disposable tubing should need to be
adjusted during a procedure, by pressing the pinch-lever on each valve toward
the cabinet.
Warning: Any manual adjustment to a valve should be attempted only if the
MCS+ device is POWERED OFF, in the READY state, or when the pumps are
stopped. At any other time, the MCS+ safety system will be alerted and will in-
terrupt the procedure. Manipulating a valve could lead to flow problems, and
eventually cause hemolysis. Chapter 6 will discuss hemolysis in further detail.
