STUVENT
With the arrival of the first COVID-19 wave and the resulting conversion of universities to distance learning, the conditions for a course at the FH Technikum Wien were redefined. A group project as part of the master’s program in mechatronics and robotics, in which a low-cost ventilator was to be conceptualized, was the result.
The basis and framework for the project was the Agorize Code Life Ventilator Challenge (https://www.agorize.com/de).
The team:
Christoph Auer, Katrin Clauss, Stefan Haberl, Jakob Hörbst, Julian Katzenschwanz, Cajetan Koschat, Stephanie Kump, Manuel Schweiger, Julia Tomasch and Wolfram Walenta.
My tasks in the project:
° role of the team leader
° mechanical design
° CAD design
° design in general
The goal:
A low-cost open source and open hardware ventilator for use in extreme emergencies. The patient should be able to be ventilated invasively, non-invasively, supportively and fully automatically with the device. The following items should be implemented:
Settings:
° Inspiratory and expiratory pressures.
° Tidal volume
° Respiration rate
° FiO2 (oxygen saturation)
Alarms:
° Overpressure or underpressure
° flow rate deviations
° Oxygen level irregularities
Additional:
° filters for inhaled and exhaled air
° ease of use
° readily available materials
Approach:
° requirements research
° functional model
° Research and selection of possible concepts
° impact model
° Detailed research
° Component selection
° CAD design
° Communication via MS teams (weekly jour fixe, defining work packages, organizing and sharing documents)
After comparing the concepts and selecting the hardware, it was possible to create an impact model.
