Suzy MCP Respiratory Hood, adult sized.

Circular in shape, the ventilator hood is founded on a 3D printed, orange base which is lined with a silicone neck seal. The patient's head can be inserted through the seal into a transparent, plastic hood. An inflatable neck cushion on the hood's interior provides patient comfort. This is inflated with a black valve at the rear of the hood which has a clip to adjust the amount of air held within the cushion. At the front of the hood are two orange, sealed access ports suitable for probes or catheters. On the left of the hood is a large, orange free-breathing valve which allows for two-way breathing if the inlet air supply is interrupted. An outlet on the valve allows a standard viral filter to be attached. Next to the large valve is a smaller outlet. On the right of the hood is another small outlet, positioned high to maximise patient comfort and facilitate prone positioning. At the very top of the hood is a vale which connects to an inflatable dead space reducer to adjust the free-air volume. Attached to both sides of the hood is a white, padded merino arm strap. This is attached to the orange base of the hood with velcro.
Brief History
In early 2020, in response to the Covid-19 pandemic and the growing international need for and shortage of ventilators, Dunedin Hospital ICU Clinical Director Dr Craig Carr had a conversation with Trade Minister David Parker about ventilator hoods that had been successfully used with Covid patients in Italy. The hoods assisted patients to breathe before their health deteriorated to the point of needing to be ventilated. Supplies from overseas were not available however.
Chris Hopkins, former Scott Tech Chief Executive, received a call from Minister Parker in March and pulled together a team including commercial and design engineers, product designers and medical experts, forming a new company, SouthMED. Using Otago Polytechnic’s rapid prototyping facilities, a hood was designed and ready for production within weeks. 3-D printers were utilised for the prototype, and subsequent testing indicated the hood was effective at treating patients with respiratory illnesses. The helmet-type hood delivers non-invasive ventilation to patients, assisting with breathing and/or inflating the lung. This example is a hood from the first production run.
