A novel pulsatile pump for extracorporeal circulation was developed. This advanced pump features adjustable beat rate, stroke volume, and controlled pressure, enabling precise hemodynamic management.

Area of Science:

Biomedical Engineering
Cardiovascular Technology

Background:

Extracorporeal circulation requires advanced pumping technology.
Existing pumps may lack precise control over hemodynamic parameters.

Purpose of the Study:

To introduce a new pulsatile pump for extracorporeal circulation.
To highlight the pump's advanced control features.

Main Methods:

Construction of a novel pulsatile pump.
Integration of variable beat rate and stroke volume control.
Implementation of controlled systolic maximum pressure and a steep pressure built-up curve.

Main Results:

The developed pump offers variable beat rate and stroke volume.
Systolic maximum pressure is precisely controlled.

Related Experiment Videos

A steep pressure built-up curve is achieved for pulsatile flow.

Conclusions:

The new pulsatile pump is suitable for extracorporeal circulation.
Its advanced features allow for tailored hemodynamic support.
