IN TUBING AND ELEMENTS
The “harness-in” tubing extends from the donor to the disposable bowl. It
contains distinct sections of disposable tubing, plus various combinations of
disposable elements.
Donor-/Blood-
line section
This section will deliver blood from the donor to the centrifuge bowl. Donor
whole blood is drawn through the needle into a single lumen section to a junc-
tion where the tubing splits into two sections: one for donor blood, the other for
anticoagulant solution.
Donor whole blood is mixed with AC from the AC tubing section and continues
up to the blood filter. On the opposite side of the blood filter are two sections of
tubing. One section leads to the DPM filter. The other section contains the blood
drawn into the centrifuge bowl by the Blood pump.
Figure 4-3, MCS+ needle tubing/sample pouch section
Pre-attached needle/tubing
This section of tubing will contain a 16G needle, a ratchet clamp and a female
luer connection. The established sterile needle connection can eliminate a
certain degree of potential contamination and contribute to the storage life of the
collection product.
Needle connector
This male luer connector attaches the needle tubing, containing a female luer
connector, to the rest of the donor/blood-line tubing.
Y-connector/three-way connector
These connectors create the junction in which the single lumen needle tubing
section can branch into multiple sections.
