Open-Source Medical Supplies Battle COVID-19

While health authorities focus on top-down measures to get COVID-19 supplies to hospitals in need, home-grown initiatives are enlisting regular people to create open-source equipment. Rather than wait for the impact of government efforts to persuade manufacturers to move into emergency production of ventilators and protective equipment, the sharing economy is already saving lives with home-made masks and 3D-printed ventilators.

A dearth of adequate medical supplies was implicated in an increase in coronavirus mortality in Italy, compared with Germany and South Korea, where supply was adequate.

Meeting a desperate need for ventilators through open-sourcing

Health authorities say the immediate short-term need is to get more ventilators, which compress and decompress air for patients who are too weak to breathe on their own.

In Ireland, a community called Open Source Ventilator sprang from a Facebook discussion to develop a simplified, low-cost, emergency ventilator that can be produced at scale from mostly 3D-printed components. Developed in collaboration with frontline healthcare workers, the emergency ventilator can be fabricated from locally sourced supplies and materials so its manufacture is not dependent on a global supply chain.

Before you rush out to hack together your personal ventilator, however, health experts warn that ventilators can do more harm than good if they are not properly constructed and operated. It is necessary to have the correct timing and air pressure, filtration, humidity, and temperature. Improper use can damage lung tissue and may even induce pneumonia. Faulty equipment can aerosolize the virus, causing it to infect others. Johns Hopkins has specifications for open-source ventilators.

Home sewing corps fashion DIY masks

There are open-source projects in numerous cities focusing on producing masks for personal uses and to protect healthcare workers. COVID-19 is one micron wide and most medical masks filter particles down to three microns. So while wearing a mask doesn’t stop all virus particles, it significantly reduces the risk of infection. There is a multitude of how-to videos for how to sew your own mask with the fabric you have but health authorities caution that cotton, as shown in this video, is not good at stopping small particles so air filters should be added to protect down to three microns.  The Federal Drug Administration has guidance on producing and wearing DIY and 3D-printed masks during the pandemic.

Home computing power is put to work for drug research

The previous initiatives are aimed at short-term relief but in order to stop the spread of the disease and curb its deadly impact, we need to develop new drugs. The SARS-CoV-2 virus depends on proteins to reproduce, including an important one called the protease. Researchers want to find a molecule that can latch onto this protein and destroy it, paving the way to a therapeutic drug. That research requires a lot of computational power, which is why computer engineers have found a way for average people to donate their computer processors when they’re not using them […]
