When Dr Iain Crossingham, respiratory consultant at Royal Blackburn Teaching Hospital’s Chest Clinic, identified the need to increase available ventilator capacity by commissioning the design and production of a single-use, consumable exhalation valve, Mackart Additive was ready to respond.

In a matter of hours, Mackart Additive developed a detailed 3D CAD model of the component, which was approved by Dr Crossingham for production to begin the very next day. “When the part arrived it worked perfectly,” says Crossingham. “Over recent days we have used the new exhalation valve to successfully ventilate a test lung, which is amazing.”
