Cardiovascular Waveform Pump for Physiology Lab

The Cardiovascular Waveform Pump simulates the ventricular hemodynamic waveform of the heart, reproducing the temporal phasing of systole and diastole. It features silicone rubber-covered heart-type ball valves, smooth flow, and fluid-contacting components made from inert materials such as silicone rubber, acrylate, and PTFE. The pumping head is easy to disassemble and reassemble and can be sterilized. It is suitable for circulating emulsions, suspensions, non-Newtonian fluids such as blood, and aqueous solutions. Four models provide minute volume ranges from 1 to 200 mL, 10 mL to 2 L, 80 mL to 6 L, and 150 mL to 10 L. It is ideal for testing flow circuits and medical devices requiring ventricular hemodynamic flow morphology. Manufactured by Atico Export with a focus on precision, durability and consistent performance for physiological research and experimental laboratory use.

Pump Mechanism :

• Positive piston actuator and ball check valves provide the proportioning action
• Stroke rate multiplied by stroke volume provides an accurate indicator of flow rate
• Positive piston action prevents changes in flow rate despite variations in resistance or back pressure
• Piston always travels to the end of the ejection stroke, independent of the volume pumped

Important Note for Blood-Based Applications :

• When using blood or blood-cell-doped solutions, hemolysis may occur over time due to mechanical closing of the valves, stroke rate, and potentially the fluid pathway.
• Users are advised to determine changes in hematocrit and/or free hemoglobin at various time points during pumping.
