Repositioning the Return Pressure Sensor
Diaphragm
Repositioning the diaphragm with fluid in the disposable tubing set
during Prime or Run mode may be necessary when
•
The return pressure sensor has either not been positioned correctly
or has been disengaged from the return pressure sensor housing.
•
The diaphragm is not in the proper position because the pressure
pod seal is dry or cracked.
To reposition the diaphragm in the return pressure sensor so that the
transducer in the housing can monitor return pressure accurately,
perform the following for either Single-Needle or Dual-Needle
procedures.
Note: Before repositioning the diaphragm, pause the system.
Single-Needle Procedure
1
Clamp the line immediately above the return pressure sensor.
2
Remove the return pressure sensor from its housing. Turn
counterclockwise to unlock.
During Prime mode:
Ensure the pinch clamp on the access line (at the access
a
manifold) and the access saline line roller clamp are open.
b Pull open the return line valve and remove the return line.
c Lower the saline container and place it on top of the centrifuge
cover (see Figure 11-3).
