Problem being addressed[edit | edit source]

Newborns that are unable to breathe on their own require mechanical assistance to breathe in order to survive long enough to develop their lungs. The cost of mechanical ventilators however, precludes their extensive use in resource-limited settings.

Detailed description of the solution[edit | edit source]

The Hansen Ventilator reduces the price and complexity of ventilators by using columns of water to control the pressure of the air instead of complex mechanical mechanisms. The ventilator can be created from off-the-shelf components and costs a fraction of the price of conventional ventilators.

Designed by[edit | edit source]

  • Designed by: Dr. Tom Hansen and Peter Richardson.
  • Manufacturing: Seattle Children's Hospital

Testing/Implementation[edit | edit source]

Animal trials began in 2010 to determine the device's efficiency. Currently, the device awaits approval for clinical trials and manufacturing in India.

Funding Source[edit | edit source]

This device was initially funded by Seattle's Children Hospital and currently there is a partnership with PATH in Seattle for field testing.
