Rapid development of a portable negative pressure procedural tent

Use of a Novel Negative-Pressure Tent During Bedside Tracheostomy in COVID-19 Patients

“…Initial testing was previously performed with healthy volunteers and a particle generator (TSI Inc, Shoreview, MN, USA) to simulate aerosol generation by a COVID-19 patient [24]. A condensation particle counter (Model 3007, TSI Inc, Shoreview, MN, USA) was used, which detects particles 0.01 μm to > 1 μm (the SARS-CoV-2 virus is 0.06-0.14 μm).…”

Widening the lens: Clinical perspectives on design thinking for public health

“…As an example, in work previously reported in The International Journal of Tuberculosis and Lung Disease, the creation of portable negative pressure helmets and tents were shown to increase the array of medical interventions able to be used with COVID-19-positive patients, while protecting healthcare workers from virus exposure during aerosol-generating procedures when negative pressure treatment spaces were not available. 6,7 Emphasis on just-in-time, interdisciplinary collaboration in design thinking led to a paradigm shift when addressing the challenge of healthcare environments with pervasive personal protective equipment Innovations to contain viral transmission by focusing on patients for novel PPE design provides for tangible improvements to existing design in infection control. These include safety in even non-traditional healthcare environments as well as efficiency and flexibility, compared to the scarce resource of a negative pressure room.…”

Use of a negative pressure procedural tent in the Emergency Department during the COVID-19 pandemic

“…Protective barrier enclosures without negative pressure have appeared ineffective in decreasing healthcare worker exposure, and instead appear to possibly contribute to increased healthcare worker exposure to airborne particles, resulting in the United States Food & Drug Administration revoking an Emergency Use Authorization that had previously supported their use [5].Initial pre-clinical testing and clinical use of a negative pressure procedural tent that mitigates the aforementioned device limitations (Fig. 1) has been previously described, demonstrating the ability to keep particle counts (0.01 μm to >1 μm) at ambient levels during AGPs [6]. The negative pressure procedural tent was developed collaboratively across disciplines (medicine and engineering) at the University of Michigan in collaboration with industry.…”

“…collapsible, and openings can be created at any location to facilitate procedures such as intubation and medication administration. Even with these openings, room air particle counts are not increased during AGPs [6]. The vacuum motor and plastic manifold base can be cleaned and reused, while the clear plastic canopy and ducting are single patient use and disposable.…”
