Effectiveness :
- Effectively contained smoke, fluorescein aerosol, and sodium saccharin aerosol within the enclosure during use
- Able to maintain negative pressure during simulated Aerosol Generating Medical Procedures (AGMP)
Design features :
- Four-sided acrylic frame
- Silicone gaskets on the arm ports
- Slanted roof to provide optimal visualization and space for intubation
- Two arm ports for the primary airway operator, and two for an airway assistant
- Connections to the patient including monitor cables, intravenous lines, and oxygen tubing may be either run under the plastic sheet or under the enclosure
- Two wall suction units (connected to standard hospital room’s in-wall vacuum suction source)
- Negative pressure (between -98 and -343 Pa)
- The caudal end of the box was enclosed using high-density polyethylene (HPDE) plastic sheeting
Drawbacks :
- Made out of acrylic, wich will easily shattter after an impact
- Armports are not perfectly sealed
- Square shape and sharp cornerergonomic
