The Aerospace Respirator (ASR) is a fully adequate low-cost and robust respirator developed by STI during the COVID-19 pandemic situation. Currently, SpaceTech focuses on the simulation of a human lung in hardware and software for medical training purpose.
SpaceTech Aerospace Respirator features
- Spin-Off LESIMA
- Novel non-invasive laser-based spirometry approach to detect O2 & CO2 in exhaled gas
- Breadboard has successfully been tested by DLR (ITP)
- Excellent time resolution
- Not pressure dependent
- Solid & robust
- Ventilation therapy
- Blood transfusion
- Nutritional therapy
- Pilot/astronaut training
- Pilot/astronaut monitoring
Fulfilling all needed medical requirements, the ASR can reduce costs by the invention of a new functional principle that also reduces maintenance, offers high robustness & fast off-the-shelf availability.
STI built the ‘ASR Prototype’ which was successfully tested at the University Hospital Gießen in April 2020. Tests included ventilation dummies, comparison tests with established respirators (e.g. Dräger/ primus), flow meters as well as different test lungs with pressure sensors. Furthermore, the ASR is optimized towards neonatal needs – in close collaboration with senior experts of the University Hospital Ulm.
SpaceTech Aerospace Respirator Mode B
STI uses the same hardware to run a lung simulator (ASR, mode B). While a generic respirator is connected to a test lung, ASR-B manipulates pressure & flow characteristics to mimic specific pulmonary symptoms – e.g., a fibrosis (hardened lung). Main objectives: training of medical staff, test & verification of respirators, reduction of animal testing. Complementary, STI has set up a SW- prototype to establish a link between respiration and the full cardiovascular system. In future work, SW-Simulator and HW-Simulator shall be connected.
