Portable aerosol hood to reduce spread of pathogens during medical procedures
A portable, transparent isolation box that facilitates safe practice of medical procedures on patients with infectious pathogens.
- Protection equipment for care providers while performing aerosol generating medical procedures
- Isolation chamber for patients carrying infectious diseases
Healthcare personnel who perform aerosol generating medical procedures such as endotracheal intubation & extubation are at acute risk of exposure to pathogens such as SARS-CoV-2. In addition, 20-30 minute mandatory waiting period between two patients significantly delays procedures and adds to the cost.
Researchers at the University of Minnesota have designed a portable isolation system for facilitating safe delivery of respiratory treatments to patients with highly infectious diseases. This system includes a transparent isolation box consisting of glove ports, a suction port fitted with HEPA filter to create negative pressure, and a partial open front through which the patient's upper body and medical equipment are introduced. The negative pressure created within the box is shown to ensure air flow can only exit through the HEPA filter, collecting infectious aerosolized particles and droplets, while leaving the air outside free of viral particles.
This isolation system has been demonstrated in hospitals to be suitable for performing aerosol generating procedures. Designed by anesthesiologists and engineers, this isolation system represents a realistic, cost-effective approach to rapidly build protection equipment for healthcare providers in direct contact with patients with infectious respiratory pathogens.
