Dyson has provided an update on its plan to build thousands of ventilators to treat coronavirus patients.
The Wiltshire-based company announced last month that it intends to build at least 15,000 ventilators.
James Dyson then unveiled the firm's design for its ventilators.
The Government has said companies bidding to make coronavirus ventilators must pass safety tests.
Dyson says it is now producing units "for final regulatory approval".
If this new ventilator passes MHRA tests, full scale production can begin.
