Abstract
A method and apparatus for obtaining the plasma portion from whole blood is provided which utilized a processor controlled plasmapheresis device and/or blood input pump to withdraw donor-weight specific plasma volumes and blood volumes from an individual.
Claims19
A method of obtaining a blood plasma fraction from a donor comprising:
- determining a donor body weight,
- entering said donor body weight into a processor,
- calculating with said processor a donor-specific body weight collection volume to be extracted from a donor, said collection volume comprising a blood plasma component and an anticoagulant component,
- pumping a blood volume from the donor with blood input pump,
- adding an anticoagulant to said pumped blood volume,
- separating said pumped blood volume into a blood cellular component having an anticoagulant component and said collection volume, and
- detecting the accumulation of said collection volume in a receptacle until said donor-specific body weight collection volume is collected.

An apparatus for obtaining a blood plasma fraction from a donor comprising:
- a blood input pump means for pumping blood directly from a blood vessel,
- a blood separation means connected to said input pump to fractionate blood into a plasma fraction and a blood cellular component fraction, and
- a processor for determining a donor-specific body weight plasma volume to be collected from the donor.
