Does pariticipating contained by plasmapheresis involve any risk of unloading someone elses blood from the apparatus used?

After I donated plasma a few times, I started wondering if it was possible to be contaminated at adjectives with someone else's blood. Plasmpheresis uses a device, and I didn't know if when I donate plasma, if there is any blood from someone else that can be injected into me. I know they use topical, sterile collection tubes and what not, but what about the member where the blood runs through the separator. Does the blood of the donator back me get disappeared in the piece of equipment and injected into me when I donate? (even a single cell of their blood)??

Answers:
No part of anyone else's blood is vanished behind, adjectives of the collection tubes, centrifuge jar, etc., is new, sterile, and disposable, and you will never come into contact near someone else's blood by donating. This used to be a risk, since they would collect your blood, then pocket it somewhere to be centrifuged, then supply you back the bit they didn't use, but the systems have changed, they are adjectives self contained, now, to protect everyone, especially the donors.
