Troubleshooting during an MCS+ Procedure 7-5
P/N 85213-30, Manual revision: B
Preparing the tubing
" Disconnect the MCS+ device from the external power source.
" Clamp the donor-line double lumen tubing close to the Y-connector.
" Clamp the AC line above the Y-connector to isolate the tubing from the do-
nor.
"
Clamp the solution line(s) and remove the tubing from the valve(s).
"
Remove the tubing from plasma valve, the donor valve, the line sensor and
the BLAD to provide necessary slack in the tubing.
" Clamp the DPM and SPM lines and remove the filters from the pressure
monitors.
"
Remove the tubing from the Blood and Transfer pumps.
Caution: Turn the pump rotors clockwise until the groove on each pump rotor is
aligned with the tubing guide, then pull the tubing upward. The operator should
verify that the tubing remains in the groove as the pump rotor is turned, in order
to avoid pinching or tearing the tubing.
" Remove the tubing from the DLAD1, DLAD2 and the tubing guide.
Removing the bowl/beginning re-infusion
" Unlock the centrifuge and open the lid.
" Remove the disposable bowl from the centrifuge well and the blood filter
from the brackets.
Caution: The operator should hold the disposable bowl and blood filter upright
and higher than the donor at all times.
" Unclamp the donor line tubing. Allow gravity force to infuse the entire
contents of the bowl up to the point of the needle connector.
"
Re-clamp the double lumen tubing approximately 5 cm from the Y- con-
nector to prevent blood from returning in the direction of the bowl.
Discontinuing the procedure
" Remove the needle from donor, disconnect the needle tubing from the dis-
posable harness and dispose of appropriately.
"
Clamp the effluent line close to the centrifuge bowl and disconnect the
collection product(s). Handle any collection products according to local
standard operating procedure.
"
Remove the remaining disposable set elements and dispose of appropri-
ately.
