5-6 Notice Messages and Troubleshooting
P/N 39551-00, Rev. F
Note: Haemonetics recommends that a 16g needle with tubing extension is
used to ensure optimal flow conditions.
1. Hermetically seal the needle line close to the needle.
2. When applicable, remove the product bags per the procedures given in the
appropriate section of the applicable protocol manual.
Note: Removal of the product bags is required only when repeat venipuncture
results in violation of the required storage conditions. For example, the product
bags should be removed if the repeat venipuncture will result in an open system
for platelet collections and product storage of greater than 24 hours is required.
3. Disconnect the donor per local SOPs.
4. Replace the needle with a new needle using one of the two methods outlined
below.
Method A: Using aseptic technique.
a. Disconnect the needle from the disposable at the Luer connector.
b. Attach new needle to disposable.
Note: This method utilizes an open system and may reduce the storage of col-
lected products to 24 hours, depending on the product collected.
Method B: Using a Sterile Connection Device.
a. Using a sterile connection device, attach a new needle to the disposable.
Note: Depending on the site SOPs, this technique may result in retention of full
product storage duration. To retain full storage duration, it is imperative that the
needle line is hermetically sealed between needle and location of sterile connec-
tion.
5. Perform venipuncture per local SOP.
6. Remove all hemostats from the disposable.
7. Continue the procedure as follows: Press the DRAW key and observe air from
needle pass through the DLAD1 and DLAD2 into the blood filter. Depending
on how full the bowl is, the MCS+ device may give the warning “DRAW not
allowed, Press RETURN to continue.” When this message occurs, press the
STOP key, followed by the DRAW key. The MCS+ device will then initiate
the Draw mode.
8. Once the air from the needle has reached the bowl, press RETURN to allow
blood and plasma to return to the donor.
9. Allow all blood and plasma to return to the donor.
