Apparatuses, systems, and methods for plasma rinseback

A method for minimizing a residual blood value via a plasma rinseback, the method comprising:

• completing a donation process via an apheresis system, the apheresis system including
• a collection bag configured to store plasma collected from a donor during the donation process,
• a return reservoir configured to collect fluid remaining in the apheresis system after the donation process is complete,
• one or more pumps configured to be actuated between an operational state and a nonoperational state during the donation process and the plasma rinseback,
• one or more lines configured to couple the collection bag, the return reservoir, the one or more pumps, and the donor, the one or more lines including a plasma line coupling the collection bag to the return reservoir, and
• a plasma valve coupled to the plasma line, the plasma valve enabling fluid to flow, via gravity, from the collection bag, through the plasma line, into the return reservoir when the plasma valve is open;
• and
• performing the plasma rinseback to return fluid within the apheresis system to the donor after the donation process is complete.
