Problem being addressed

In remote areas and resource-limited settings, clinics may lack expensive, electric nebulizers to induce sputum samples for tuberculosis diagnosis and respiratory treatments.

Detailed description of the solution

We have developed two versions of the Human Powered Nebulizer. One is hand-cranked; the other is pedaled like a bicycle. The health care provider operates the HPN while the patient induces a sputum sample or receives treatment. This technology is inexpensive and portable, putting respiratory treatment and diagnostics in the hands of even the most remote clinics.

Designed by

  • Designed by: The Human Powered Nebulizer Project at Marquette University. Official website: [1] .
  • Manufacturing: Milwaukee, Wisconsin, USA

When and where it was tested/implemented

The first clinical trial was conducted in South African in 2010, in conjunction with the London School of Hygiene and Tropical Medicine and the Desmond Tutu HIV Centre. Additional clinical and field trials are currently being conducted in Malawi and El Salvador.

Funding Source

Private funding provided by Marquette University. Funding also provided through the National Collegiate Inventors and Innovators Alliance (a philanthropic competition).
