Flow pumping system for physiological waveforms [PDF]
Medical & Biological Engineering & Computing, 2010 A pulsatile flow pumping system is developed to replicate flow waveforms with reasonable accuracy for experiments simulating physiological blood flows at numerous points in the body. The system divides the task of flow waveform generation between two pumps: a gear pump generates the mean component and a piston pump generates the oscillatory component ...

Respiratory maneuvers in echocardiography: a review of clinical applications
Cardiovascular Ultrasound, 2009 During echocardiographic examination, respiration induces cyclic physiological changes of intracardiac haemodynamics, causing normal variations of the right and left ventricle Doppler inflows and outflows and physiological variation of extracardiac flows.

A novel roller pump for physiological flow [PDF]
Artificial Organs, 2020 AbstractHaving physiological correct flow waveforms is a key feature for experimental studies of blood flow, especially in the process of developing and testing a new medical device such as stent, mechanical heart valve, or any implantable medical device that involves circulation of blood through the device.

Characteristics of Blood Vessel Wall Deformation with Porous Wall Conditions in an Aortic Arch
Applied Rheology, 2014 Blood vessels have been modeled as non-porous structures that are permeable to solutes mixed in the blood. However, the use of non-physiological boundary conditions in numerical simulations that assume atmospheric pressure at the outlet does not ...
