Pulsatile Blood Pumps

Pulsatile Blood Pump

The Pulsatile Blood Pump 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.

The Pulsatile Blood Pump truly simulates the pumping action of the heart. Designed to minimize hemolysis. Ideal for moving emulsions, suspensions, and non-Newtonian fluids such as blood. 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.


Features

  • Minimal hemolysis 
  • Models for mice to large animals 
  • Ideal for moving emulsions, suspensions, and non-Newtonian fluids such as blood


Outstanding Performance

The pulsatile output closely simulates the ventricular action of the 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. 


Pump Mechanism

A positive piston actuator and ball check valves provide the 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. 


Specials

Harvard Apparatus 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 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.
