7-6 Troubleshooting during an MCS+ Procedure
P/N 85213-30, Manual revision: B
Repeat
venipuncture
procedure
If a vein becomes infiltrated at any point during a collection procedure, and
blood can no longer flow through the needle, Haemonetics recommends that the
uncollected blood components in the bowl and tubing be returned to the donor
using a new intravenous pathway.
The MCS+ operator should be familiar with the local standard operating proce-
dures when repeating a venipuncture, as well as product storage-duration
requirements when changing a needle.
This procedure as described by Haemonetics must be performed using strict
aseptic technique or a sterile connection device.
" Press the STOP key on the control panel.
" Hermetically seal the donor-line tubing by clamping both sides of the nee-
dle connector as follows:
!
Close the ratchet clamp on the needle tubing.
!
Place a second clamp on the double-lumen tubing on the opposite side
of the Y-connector.
! Remove the needle from the donor, cut the contaminated needle and
dispose of correctly.
!
Place the donor-line tubing aside to prevent contamination.
Caution: At this point, the operator should remove the pressure cuff from the do-
nor and appropriately treat the vein, if infiltrated.
" Prepare and perform a new venipuncture, securing the new needle and
tubing.
"
Prime the new needle tubing with donor blood and close the ratchet
clamp.
" Disconnect the old needle tubing (minus the needle) from the disposable
set and dispose of correctly.
"
Connect the new needle tubing to the disposable harness and unclamp at
both sites.
If aseptic technique has been used, any air in the tubing is considered as sterile,
and the collection product will remain viable. Any air in the tubing can be
displaced toward the blood filter or disposable bowl by the following actions:
" Press the Draw key to advance any air present from the needle through the
DLAD1 and DLAD2 into the blood filter.
Note: Depending on the quantity of blood already present in the bowl, the oper-
ator may receive the NOTICE message “DRAW not allowed, press RETURN to
continue”. If this should occur, the operator should press the STOP key, followed
by the Draw key. The MCS+ DRAW mode will then be initiated automatically.
Once any air from the needle has reached the bowl, the operator should:
" Press the Return key to re-infuse the blood components in the bowl.
