Patient IsoBox


This medium sized isolation box is used during respiratory therapy procedures. The IsoBox covers the patient limiting sputum and aersol from spreading to personnel or equipment; making these procedures less dependent on PPE. 

The box design is not novel, but the IHub Fab Lab developed silicone diaphragm, is.  This layered barrier limits the amount of particulate transferred during treatment.

Walk-In IsoBox


The walk-in isolation box limits the burden on PPE supplies during testing procedures. These lightweight, durable boxes protect healthworkers and patients from viral particulate. The plastic and metals used are easily sanitized.

Mobile, PPE Decontamination Containers

Critical PPE like N95 respirators and other medical masks continue to be in short supply. While manufactuers are producing these products quickly as possible, decontamination systems are proving necessary as stop-gap measures extending the life of regularly, single-use masks.

Pathology researchers at OU's Health Sciences Center have tested just such a system using vapor phase hydrogen peroxide and relatively few pieces of equipment to disinfect hundres of masks in under three hours. System is easily set up in mobile containers like conex boxes.
