The main disadvantages of the discontinuous flow cell separator Haemonetics 30 (Haemonetics Corp. Natick, Mass.) compared to continuous flow separators are that there is a longer course procedure and a larger amount of donor's blood in extracorporeal circulation. These drawbacks can be reduced by means of a simple technical set-up.
Since plasma reinfusion may commence as soon as the bowl filling stage is completed, the amount of blood in extracorporeal circulation can be greatly reduced simply by substituting a three-way setfor the two-way reinfusion set (BT 293).
