• ECMO applications
  Support with extracorporeal membrane oxygenation is used as a rescue procedure when care via the lungs using invasive ventilation can no longer be guaranteed. ECMO therapy ranges from a few hours to several weeks. The key element of ECMO is the oxygenator. This is where oxygen is enriched and carbon dioxide is eliminated from the blood. The functionality of this component in the ECMO system is of crucial importance.
  • Research areas of current oxygenator concepts
    Investigation of current research developments, such as novel concepts or integration of functions into the oxygenator component.

  • Market analysis of existing gas mixing systems for ECMO

• 3D printing for medical technology
  Additive manufacturing of components is a fast and cost-effective process for the production of very small series. This process is also being used more and more frequently in the field of medical technology.
  • Topics on request
• Respiratory technology and respiratory gas analysis
  • Investigation of the current state of research and identification of adverse events in rescue vehicles

04. Kidney

• Investigation of the current state of research in the field of electrical impedance tomography
  Use of impedance tomography in the field of organ perfusion and evaluation of organs

• Current research areas in the field of kidney and liver replacement therapy

• Analysis and processing of hyperspectral images

Individual topic suggestions on current topics of the working group are possible at any time.

Topics for student research projects and diploma theses include:

• Development of device components and control strategies for extracorporeal membrane oxygenation (ECMO)
  • Conceptual design of an evaluation of the oxygenator in ECMO application
• Development of device concepts for ex vivo organ perfusion
  • Further development of the organ storage based on existing concepts
  • Conceptual design and development of an emergency power system
  • Development of components for the controlled oxygenated reperfusion (COR) of donor kidneys for NMP

  • Evaluation of existing data sets (blood data, perfusion data, image data) with regard to existing standards

  • Further development of existing topology concepts with regard to optimized usability

• Research in the field of 3D printing for medical technology
  • Conceptual design of in-process quality assurance methods for 3D printing
  •  Optimization and modularization of an existing silicone 3D printing system
• Investigation of oxygen enrichment in air vehicles during high-flow oxygen therapy

Organ models
In surgical training of minimally invasive procedures, the use of animal organs should be avoided. This requires the provision of technical models to simulate human physiology. The Institute of Biomedical Engineering at the Technical University of Dresden has developed innovative organ phantoms of the gastrointestinal tract, including the liver and gall bladder, in cooperation with the Research Institute for Leather and Plastic Sheeting FILK in Freiberg and the Research Group for Minimally Invasive Interdisciplinary Therapeutic Intervention (MITI) at the Technical University of Munich. These are characterised by a realistic appearance (shape, size, colour, texture) and haptics (weight, viscosity, elasticity) as well as by their suitability for surgical preparation methods such as sharp or electrocautery cutting, clipping, grasping, injecting, suturing, stapling and for display in imaging procedures. The developed collagen-based organ phantoms were integrated into an ELITE surgical phantom to provide a training unit for various applications, e.g. cholecystectomy (removal of the gallbladder).
