Early models were based on assumptions and parameters from initial research by the team. Each iteration was refined with input from medical professionals and design changes to the box itself. The later simulations also discovered that heavier virus particles, similar in weight to water droplets, stick to the top and side surfaces of the box, while the suction tube effectively removes smaller particles. Our insights have resulted in improvements to the shield’s effectiveness for both clinical teams and patients alike.
One shield, many uses
As with everything else in the response to the pandemic, work has been determined and rapid. The MTC has been receiving requests for a number of the shields, and dozens have already been trialed within hospitals.
In addition to protecting hospital staff, the shield box has the potential to decrease cleaning times between patients, a vital factor to alleviate the consistent pressure on resources within hospitals and intensive care units during this pandemic. Treatments and surgeries not associated with COVID-19 have also been delayed following the outbreak. Implementation of the shield will help staff navigate this backlog effectively and efficiently post crisis.
Additional potential uses for the AGP shield are also being investigated, including possible applications in dentistry and endoscopy where its use will be vital as these procedures are often carried out without the full benefit of sophisticated air handling capability that is found in operating theatres.
