CLEAN : Home appliances firm makes ventilator for coronavirus patients

The video tutorial discusses the design and development of a ventilator using repurposed syringe bodies and valve blocks. It highlights the challenges faced in creating a simple, mass-producible design without special seals. The project was initiated in response to a government request for 30,000 ventilators in two weeks. The team leveraged their expertise in airflow and vacuum cleaner design to adapt to medical requirements. The focus was on simplifying the design to enable high-volume production, ensuring the ventilators deliver consistent oxygen-enriched air to patients.

What was the main challenge in designing the valve block for the syringe body?

• Finding a suitable material

• Creating it without special seals

• Ensuring it was lightweight

• Making it aesthetically pleasing

How can the resuscitation bag be used if there is no nearby oxygen supply?

• It requires manual operation

• It cannot be used without a supply

• It can be used with an oxygen cylinder

• It can be powered by electricity

What prompted the team to start working on ventilators?

• A university research project

• A personal interest in medical devices

• A request from a senior government official

• A new business opportunity

What expertise did the team leverage to understand ventilator requirements?
