UK life sciences manufacturer Porvair Sciences has provided an important component in the manufacture of Continuous Positive Airway Pressure (CPAP) devices, which can help keep Covid-19 patients out of intensive care.

The CPAP breathing aid has been developed in just five days by mechanical engineers at University College London and clinicians at University College London Hospital working in conjunction with Mercedes-AMG High Performance Powertrains.

An important component in the device is a machined Vyon F Silencer developed and delivered in just five days by Porvair Sciences. The device has been used extensively in hospitals in China and Italy to help Covid-19 patients with serious lung infections to breathe more easily when oxygen alone is insufficient.

Kevin Doolan, general manager of Porvair Sciences, said: " By focusing our manufacturing resource, we were able, within days, to deliver the Vyon high-density polyethylene component that functions as a silencer for the CPAP device. He added that the path of the Vyon porous plastic materials ensures the air flow has to escape into the atmosphere by expanding through the porous structure, thus reducing the noise level.
