Clamps
The X
TRA
uses three clamps to control the flow of fluids during normal processing of blood. The clamps
determine which fluids are routed at each processing stage. The clamp lid allows fixing the tubing lines
in place for proper clamp functioning during the case (see Figure 3-15).
Figure 3-15 Left: Clamps With Clamp Lid Open | Right: Clamp Lid Closed and Latched
The location and state (open or closed) of the three clamps during each processing phase are shown
in the following table. A clamp is closed when the clamp plunger is extended and totally occludes the
tubing, shutting off all fluid flow.
The clamps are electronically controlled and mechanically operated in the all operating modes. If the
microprocessor detects an error in the operation of the clamps, an audible and visual alarm occurs and
the system stops processing (refer to “Alarms and Warnings” on page 14-1).
