Talk given at OpenTech 2015 OpenPump is an open-source hardware project to build a syringe pump, a device used to dispense fluids over a set period of time. Syringe pumps are used in hospitals to administer medication, but also in lab environments for activities like microfluidics, bioreactors and bioprinting. This talk will discuss the design and development of OpenPump, as well as the challenges and opportunities for open-source medical devices.

2. Hose clamp

3. Raspberry Pi peristaltic pump

4. Peristaltic pump from Adafruit (£17)

5. CT scanner

8. OpenPump

9. • Anyone can contribute and help improve the design
• Design can be modified for very specific use cases
• Vendor lock-in prevented
• Increases safety, security and robustness by allowing
more people to inspect and improve the designs
• Allows manufacturers to compete on usability,
support and interoperability
Why OSHW?

10. 70-90% of al donated medical devices
never function as intended

15. OpenSCAD

16. Fritzing

19. Number of downloads that result in a manufactured
product
Value of OSHW
Savings of between
$778,000 and $12.4 million
over one year
VD(t) = (Cp - Cf) x P x ND(t)

20. Certification is time-consuming and expensive
Liability
Incompatibility with traditional standards
Challenges for medical OSHW
