truly simulates the pumping action of the heart. It features silicone
rubber-covered heart-type ball valves and smooth flow paths which
minimize hemolysis. Only inert materials like silicone rubber, acrylic
plastic, and PTFE contact the fluid. The pumping head is easy to take
apart and reassemble and can be sterilized.
heart. This action provides physiological advantages in blood flow for
perfusion in cardiovascular and haemodynamic studies. It is ideal
for isolated organ perfusion, whole body perfusion, blood transfers,
hydration/dehydration procedures, and blood cellular profile studies.
proportioning action. The product of stroke rate times stroke volume is
an accurate indicator of the flow rate. Positive piston action prevents
changes in flow rates, regardless of variations in resistance or back
pressure. The piston always travels to the end of the ejection stroke,
independent of the volume pumped. The Pump completely empties at
each cycle.
Harvard Apparatus now offers the pumping head in polysulfone which
is autoclavable. The standard models use acrylic which must be
sterilized using ethylene oxide or other methods. This new material
makes it much easier to maintain sterility.
Harvard Apparatus now also offers a new control method for the blood
pumps. Now the pump can be controlled from an external voltage
source; 0 to 10 volt DC signal can be used to control the stroke rate
and phasing of the pump. External control interfaces the blood pump
with a computer to generate advanced cardiovascular waveforms and
more control over pressure curves. Please call for more information.
