Unser Labor ist mit einer breiten Palette von Instrumenten für theoretische und experimentelle Untersuchungen von Bioflüssigkeiten und Hilfsgeräten für menschliche Organe ausgestattet.
This fully instrumented mock circulation was developed for assessment of the performance of an axial flow, pneumatically operated left ventricular assist device (LVAD). Due to a high degree of flexibility and a wide range of hemodynamic states that can be simulated, the mock circulation is suitable for in-vitro experiments with various assistive devices being developed for support of the cardiovascular system.
Mock circulation
Main functions of the fully instrumented test loops are
- assessment of mass transfer and pressure drop in membrane contactors
- determination of characteristic flow-pressure curves of blood pumps
- assessment of hemolysis caused by assist devices

We use a TSI Micron Resolution Particle Image Velocimeter for measuring flows in microchannels based on an inverted microscope with flow field in a size range from <100 micron to 2mm, and 80nm-1micron imaging resolution per pixel in combination with a powerful compact Dual Cavity Laser.

Currently we use a Kudo 3D printer for parts with high resolution and biocompatible resin materials and a Markforged Mark Two printer for composite parts with high strength, stiffness and durability out of carbon fiber reinforced material, fiberglass and kevlar.
A two component Laser Doppler Velocimetry (LDV) system (TSI Inc.) enables the accurate, pointwise measurement of fluid velocities and turbulence quantities.
