Boyce Technologies developed the ventilator based on work by Scott Cohen, who runs a technology centre for researchers and start-ups known as New Labs, and Marcel Botha, who runs a product design and development company known as 10XBeta.
The project gained national attention in the US when it was featured in a long article in the The New York Times in April.
Of the project, Boyce says on its website: "At the end of March, we partnered with NewLab and 10XBeta to support hospitals in critical need in New York City.

"The New York City Economic Development Corporation has ordered the first 3000 units on behalf of NYC, and plans are in progress to expand distribution of Spiro Waves to areas of the country and the world where the COVID-19 pandemic is most severe."
The gang behind the attack has, as usual, leaked some data stolen from the company's site on its website on the dark Web.
