Low-Cost Portable Ventilator For Emergency Relief


For a class project at MIT called Precision Machine Design, which involved creation of devices that could help ease modern hospital problems, a team of students developed a low-cost, portable ventilator for keeping patients breathing in places with no access to mechanical ventilators. This simple and inexpensive device could especially be of help in emergencies.

The $100 ventilator features a pump, which is encased in a plastic box with a battery, motor and controls. Three control knobs are there to adjust the total volume of air delivered in each breath, to calculate the number of breaths per second, and assessing the frequency of inhaling and exhaling. The device relies on a curved plastic cam for compression and release of air.
