About Badger Box

The Badger Box helps healthcare providers most at risk when placing breathing tubes. This is because placing a breathing tube aerosolizes viral particles in the mouth and nose of the infected patient which can then infect anyone standing nearby. This model of infection is referred to as airborne transmission.

A group of surgeons, anesthesiologists, and engineers led by pediatric surgeon (Dr. Hau Le) at the University of Wisconsin has developed an innovative device (The Badger Box) that can reduce risks of airborne transmission from patients with COVID-19 to doctors, nurses, respiratory therapists, intensivists and others who are directly taking care of them.

The Badger Box was designed, engineered, and tested at University of Wisconsin-Madison in collaboration with Sector 67. The box prevents direct splashing of patients’ droplets onto healthcare providers who perform procedures on these patients.

Patients who are symptomatic or who have tested positive for COVID-19 are placed in the box as pictured. Negative pressure (suction) draws airborne droplets out of the box, preventing them from spreading into the space around the patient.

The Badger Box has been approved by UWHealth to be used in all eight UWHealth facilities.


Our aim is to post on our website:

[1] Open Source Design: We’ve posted the open-source design and parts list below, and will update the design as we receive feedback and complete further testing.  See legal disclaimer at the bottom of this page. If you would like to make these intubation boxes yourself, please see the “Manufacturing Resources” section as it updates.

[2] Supplier Resources: A list of suppliers for plastic, 3D printed parts, gloves, etc. If you are a supplier or looking for suppliers, please see the “Supplier Resources” section as it updates.

[3] Buyer Resources: A list of manufacturers with expected production rates for making Badger Boxes. If you are looking for manufacturers selling face shields, please see the “Buyer Resources” section as it updates. Note: We encourage you to pursue multiple sources since the supply of PPE is still very limited.

[4] E-mail List: An email list with healthcare facilities looking for intubation boxes so we can notify them if we become aware of any developments. If interested, please fill out the intake form here.
