Scientists at TU Bergakademie Freiberg develop new ways of emergency ventilation

20.04.2020

Scientists at TU Bergakademie Freiberg are currently testing a prototype of a pressure-controlled emergency ventilator. The device, which can be built with simple tools and is easy to maintain, could be used primarily in developing countries for the ventilation of emergency patients suffering from lung diseases.

To this end, the mine rescue team of TU Bergakademie Freiberg and the Institute for Machine Elements, Design and Production have combined their expertise.

"We know how ventilators work and Prof. Matthias Kröger and his design team know how to build such devices", explains Frank Reuter, head of mine operations in the research and training mine "Reiche Zeche" at TU Freiberg.

The first prototype has already been produced and is currently undergoing various tests to check and further improve its functions. No electricity is required to operate the emergency ventilator, only compressed air or oxygen.

It mainly consists of a control piston with which different parameters, such as the ventilation pressures during inhalation and exhalation (PIP, PEEP) or the respiratory rate, can be adjusted.

In addition, the oxygen concentration can be optionally controlled. Those are important factors to be able to ventilate emergency patients who have been infected with a lung disease.

The scientists from Freiberg focus mainly on the supply of lung care in poorer countries with little technical know-how and a high population density.

"Our prototype is designed in such a way that it can be reproduced, maintained and cleaned with simple means and a few tools," explains Dr. Robert Szlosarek from the Chair for Machine Elements at the TU Bergakademie Freiberg.

The scientists would like to communicate their idea to groups engaged in development aid and embassies.

Im Focus: Electron cryo-microscopy: Using inexpensive technology to produce high-resolution images

Biochemists at Martin Luther University Halle-Wittenberg (MLU) have used a standard electron cryo-microscope to achieve surprisingly good images that are on par with those taken by far more sophisticated equipment. They have succeeded in determining the structure of ferritin almost at the atomic level. Their results were published in the journal "PLOS ONE".

Electron cryo-microscopy has become increasingly important in recent years, especially in shedding light on protein structures. The developers of the new...

Im Focus: Electrons in the fast lane

Solar cells based on perovskite compounds could soon make electricity generation from sunlight even more efficient and cheaper. The laboratory efficiency of these perovskite solar cells already exceeds that of the well-known silicon solar cells. An international team led by Stefan Weber from the Max Planck Institute for Polymer Research (MPI-P) in Mainz has found microscopic structures in perovskite crystals that can guide the charge transport in the solar cell. Clever alignment of these "electron highways" could make perovskite solar cells even more powerful.

Solar cells convert sunlight into electricity. During this process, the electrons of the material inside the cell absorb the energy of the light....
