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: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

Im Focus: Tailored light inspired by nature

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.

Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
