ABSTRACT:
A disposable intravenous pump chamber cassette for an intravenous administration set which is specifically fabricated for use with the administration of blood. The pump chamber is specifically constructed to be utilized in conjunction with an intravenous pump having a driver to activate a diaphragm member and includes an improved outlet valve member having an outwardly extending lateral wall surface to direct the blood away from the biasing mechanism for the outlet valve member to thereby substantially reduce hemolysis.
