  1. Gerrit Niezen! Postdoctoral researcher! Swansea University! Wales, United Kingdom making

    medical devices safer Open Source Hardware (OSHW) 
 Medical Devices Workshop @gendor
  2. What is ! open source hardware?

  3. "Open-source hardware creates products driven by capitalism rather than monopolies,

    an open environment for sharing information, and a powerful opportunity for companies and individuals to learn from each other."! Joshua M. Pearce, Open-Source Lab
  4. 10 commercially successful open source hardware companies in 2013
 http://bit.ly/oshwcomp!

    ! • Arduino! • OpenROV! • DIY Drones! • Little Bits! • Sparkfun • Adafruit! • MakerBot! • UltiMaker! • Raspberry Pi! • beagleboard.org
  5. Robohand

  6. Hose clamp

  7. Spectrometer

  8. Raspberry Pi peristaltic pump

  9. Peristaltic pump from Adafruit ($25)

  10. Syringe pump (0.3ml intradermal)

  11. $200 OpenFuge

  12. PhoneScope

  13. Arduino-based ketosis detector

  14. Open source electrophysiology: FlexDrive

  15. OpenBCI

  16. CT scanner

  17. None
  18. e-Health sensor platform

  19. What can be shared? • Original design files, e.g. 2D

    drawings, CAD files, circuit schematics and layouts! • Bill of materials! • Software and firmware! • Photos! • Instructions and other explanations! http://www.oshwa.org/sharing-best-practices/
  20. Other licences include: 
 TAPR (Tucson Amateur Packet Radio) Open

  21. help others reproduce your work! help others use your product!

    explains design rationale Why document?
  22. Uses oManual standard (IEEE 1874) Documentation

  23. None
  24. Sharing designs Why use web-based design tools?
 Easier to share

    design and collaborate in real-time! Sharing completed CAD models
 Thingiverse, GitHub viewer, Sketchfab
  25. Free for open source: 
 https://upverter.com/pricing/alt/ Can link to GitHub

    Open design reviews
  26. “Given enough eyeballs, all bugs are shallow” (?)
 Eric S.

    Raymond Safety & Security ability to fix the bug yourself! standards are necessary but not sufficient
  27. Standards Medical devices - Application of usability engineering to medical

    devices ISO/IEC 62366:2007 Process standard ANSI/AAMI HE75:2009 Design principles standard Human Factors Engineering - Design of medical devices Other standards for electrical compliance, risk management, alarm systems, graphical symbols and labelling
  28. Source: Withings Media Kit Design-led focus
