Making a Soft Elastic Pulsation Pump (SEPP)

In this work, a soft-elastic pulsation pump (SEPP) has been made and investigated. Here, 3D printing was used to make casting molds melt-removal method using wax employed. The SEPP of silicone rubber driven by an external squeezing mechanism. A one-way valve also which prevented backflow after the fluid squeezed out chamber. material characteristics including durability were examined. operating parameters confirmed differential pressure 100 mm Hg in close flow loop. average rate 2 L/min, while yielding peak 8 stroke volume 70 mL. preliminary trial fresh animal blood had shown that good protection on blood. Therefore, within resources available, interesting idea for effective proposed realized laboratory. technical details described, experimental results reported here form basis making higher capacity SEPPs. This effort may help its way ventricular assist device.
